IRS Requirements for Gift and Estate Tax Business Valuations
A gift or estate tax business valuation is not just a price estimate. It is a documented opinion of fair market value for a specific ownership interest, on a specific valuation date, prepared for federal transfer-tax reporting and potential IRS review. That distinction matters for owners of family companies, executors, trustees, CPAs, estate-planning attorneys, and heirs because a weak valuation can create gift tax exposure, estate tax disputes, penalty risk, family conflict, and costly audit defense.
For gift tax purposes, the Internal Revenue Code generally values property at the date of the gift; for estate tax purposes, the gross estate generally includes the value of property owned at death, subject to special rules and elections that should be handled by qualified tax advisors (26 U.S.C. §§ 2031, 2032, 2512). Treasury regulations define fair market value using the familiar hypothetical willing-buyer and willing-seller standard: the price at which property would change hands between parties who are not compelled to act and who have reasonable knowledge of relevant facts (Treas. Reg. §§ 20.2031-1, 25.2512-1). In a closely held business, applying that standard requires far more than selecting a round-number EBITDA multiple or using book value.
An IRS-ready business appraisal should identify the legal interest being valued, explain the rights and restrictions attached to that interest, analyze the company’s financial performance and risk, select appropriate valuation methods, support any discounts, and reconcile the conclusion in a way that a knowledgeable reviewer can follow. Revenue Ruling 59-60 remains a foundational framework for valuing closely held stock for estate and gift tax purposes because it emphasizes company history, financial condition, earning capacity, dividends, goodwill, prior transactions, block size, and comparable companies rather than a single formula (Internal Revenue Service [IRS], 1959). Professional valuation standards, including AICPA SSVS No. 1 and USPAP, reinforce the same basic theme: credible valuation work requires defined scope, relevant evidence, competent analysis, and clear reporting (American Institute of Certified Public Accountants [AICPA], 2007; The Appraisal Foundation, 2024).
This article explains what the IRS expects in practical terms. It is educational and is not legal, tax, or investment advice. Gift and estate tax reporting, elections, adequate disclosure, and penalty defenses are fact-specific. Coordinate with a qualified CPA, tax attorney, and valuation professional before filing a transfer-tax return or relying on a business valuation for a major planning transaction.
Why Gift and Estate Tax Valuations Are Different From Ordinary Sale Pricing
Transfer-tax value is a tax-law fair market value opinion
A business owner may have several numbers in mind: an asking price, a buy-sell agreement formula, book value, a lender’s underwriting value, an internal planning estimate, or a broker’s opinion of what the company might sell for. None of those is automatically the value required for federal gift or estate tax reporting. Transfer-tax valuation is anchored in fair market value under the Code and Treasury regulations, not merely the owner’s expectations or a negotiated family price (26 U.S.C. §§ 2031, 2512; Treas. Reg. §§ 20.2031-1, 25.2512-1).
A professional business valuation for gift or estate tax purposes asks a narrower and more disciplined question: what would a hypothetical willing buyer pay, and what would a hypothetical willing seller accept, for the exact ownership interest at the relevant valuation date, when both parties are reasonably informed and neither is forced to act? That question often differs from what a strategic buyer might pay for 100% control, what family members might agree to privately, or what a bank might accept as collateral support.
For example, a 100% sale of an operating company may include synergies, buyer-specific integration plans, employment agreements, and post-closing adjustments. A gift of a 20% noncontrolling LLC interest to a trust may involve no control over management, limited transferability, uncertain distributions, and a long expected holding period. Those are different economic interests, even if they relate to the same company.
The business interest matters as much as the business
One of the most common valuation mistakes is confusing enterprise value with the value of a specific ownership block. A company may have a total business enterprise value, but the transferred or inherited interest may be a minority voting interest, a nonvoting interest, a limited partnership interest, a profits interest, or an LLC membership interest subject to transfer restrictions. The rights attached to the interest affect fair market value.
The appraiser should review shareholder agreements, operating agreements, partnership agreements, voting provisions, distribution provisions, redemption rights, transfer restrictions, buy-sell terms, and any relevant state-law rights. Revenue Ruling 59-60 instructs valuers to consider the size of the block being valued and the nature of the security (IRS, 1959). Revenue Ruling 93-12 adds that, in the gift-tax context addressed by the ruling, family attribution should not automatically eliminate minority-interest analysis merely because other family members own shares (IRS, 1993). At the same time, IRC § 2703 and its regulations can cause certain options, agreements, rights, or restrictions to be disregarded if they do not meet statutory and regulatory requirements (26 U.S.C. § 2703; Treas. Reg. § 25.2703-1).
The result is a careful, interest-level analysis. The value of 100% of the company is not simply multiplied by the ownership percentage without asking whether control, marketability, restrictions, or other rights change the economics of that ownership block.
Practical stakes: reporting, audits, penalties, and planning
Gift and estate tax valuations affect more than the tax shown on a return. They can influence use of lifetime exemption, estate liquidity planning, basis considerations, family equalization, trust funding, charitable planning interactions, buy-sell implementation, and future IRS audit risk. For gift tax returns, adequate disclosure can be important because the limitations period for gift valuation issues generally depends on proper disclosure of the gift and supporting information (Treas. Reg. § 301.6501(c)-1). For estate tax returns, a closely held business appraisal may become one of the most important attachments supporting the value reported on Form 706 (IRS, 2025a, 2025b).
Accuracy-related penalty rules also make documentation important. IRC § 6662 addresses penalties for valuation misstatements and other understatements, while IRC § 6664 provides reasonable-cause and good-faith concepts that may be relevant in appropriate circumstances (26 U.S.C. §§ 6662, 6664). A credible appraisal does not guarantee acceptance by the IRS, but a poorly supported number can make the taxpayer’s position much harder to defend.

The IRS Fair Market Value Standard
Estate tax valuation under IRC § 2031
IRC § 2031 provides that the value of the gross estate includes the value at the time of death of all property, real or personal, tangible or intangible, wherever situated (26 U.S.C. § 2031). For a business owner, that can include shares of a closely held corporation, LLC units, partnership interests, notes, options, or other business-related property. Treasury Regulation § 20.2031-1 states that fair market value is the price at which the property would change hands between a willing buyer and willing seller, neither being under compulsion and both having reasonable knowledge of relevant facts (Treas. Reg. § 20.2031-1).
That definition is deceptively simple. In a private company, there may be no active market quotation. The estate must report a value for an ownership interest that may not have traded for years. The appraiser must therefore reconstruct fair market value from company documents, financial statements, industry data, market evidence, assets, liabilities, cash flows, rights, restrictions, and risks known or reasonably knowable at the valuation date.
Gift tax valuation under IRC § 2512
For gift tax purposes, IRC § 2512 states that if a gift is made in property, the value of the property at the date of the gift is considered the amount of the gift. It also provides that where property is transferred for less than adequate and full consideration in money or money’s worth, the excess value can be deemed a gift (26 U.S.C. § 2512). Treasury Regulation § 25.2512-1 uses the same willing-buyer/willing-seller concept and states that value depends on all relevant facts where market quotations are not available (Treas. Reg. § 25.2512-1).
This is why valuation planning is essential before transferring closely held business interests to family members, trusts, or other related parties. A parent who transfers LLC units based on an unsupported internal estimate may later face an IRS challenge if the company was worth more than reported or if the transferred interest was inadequately described. The valuation should be contemporaneous with the completed gift and should match the legal documents, entity records, ownership ledger, and tax return disclosure.
Reasonable knowledge of relevant facts for private companies
The fair market value standard assumes both hypothetical parties have reasonable knowledge of relevant facts. For a private company, that knowledge usually includes financial history, current operating trends, customer concentration, supplier risk, debt, working capital needs, capital expenditures, management depth, owner compensation, legal restrictions, pending transactions, industry conditions, and economic conditions. Revenue Ruling 59-60’s eight-factor framework remains useful because it directs attention to these facts rather than to a single shortcut (IRS, 1959).
Professional standards also matter. AICPA SSVS No. 1 discusses valuation engagements for a business, business ownership interest, security, or intangible asset and requires valuation analysts to consider relevant approaches and methods, assumptions, restrictions, and reporting needs (AICPA, 2007). USPAP emphasizes ethics, competency, scope of work, and credible reporting (The Appraisal Foundation, 2024). NACVA’s professional standards similarly reinforce structured analysis for credentialed valuation analysts (National Association of Certified Valuators and Analysts [NACVA], n.d.).
Avoiding hindsight and forced-sale assumptions
Fair market value is generally determined as of the valuation date. A valuation should not use later events as if they were certain on the gift date or date of death. Later information may sometimes illuminate conditions that were known or knowable at the valuation date, but hindsight should not replace the required valuation-date analysis.
The regulations also caution against forced-sale assumptions. Treasury Regulation § 20.2031-1 states that fair market value is not determined by a forced sale price (Treas. Reg. § 20.2031-1). Liquidation value may be relevant if liquidation is the appropriate premise of value for the facts, such as an asset-holding entity where sale or liquidation is economically likely, but it should not be assumed simply because assets exceed earnings value. Estate of Giustina illustrates that courts scrutinize method weighting and liquidation assumptions when they are not aligned with economic evidence (Estate of Giustina v. Commissioner, 2014).
| Fair market value element | Evidence to retain |
|---|---|
| Willing buyer and willing seller | Valuation report describing hypothetical market participants |
| No compulsion | Facts showing ordinary valuation premise, not forced sale |
| Reasonable knowledge | Financials, agreements, industry data, management information |
| Relevant market | Comparable company or transaction data, if used, with adjustments |
| Specific interest | Ownership percentage, voting rights, transfer restrictions, agreements |
| Correct date | Gift documents, date-of-death records, interim financial statements |
Valuation Dates: Gift Date, Date of Death, and Alternate Valuation
Gift date for completed transfers
For gifts, the valuation date is generally the date of the completed gift (26 U.S.C. § 2512; Treas. Reg. § 25.2512-1). The valuation analyst needs the documents that prove what was transferred and when. These may include an assignment of membership interest, trust agreement, board or manager consents, amended ownership schedules, stock ledger entries, partnership capital-account records, and any required approvals under the entity’s governing documents.
A mismatch between the appraisal and the legal documents can create problems. If the valuation says a 20% nonvoting LLC interest was gifted on December 31, but the assignment was signed January 5 and the operating agreement did not authorize the transfer until later, the valuation date and interest description may need correction. The appraiser is not the tax attorney, but the appraiser must know what property is being valued.
Estate date of death
For estate tax purposes, the default valuation date is generally the decedent’s date of death (26 U.S.C. § 2031; Treas. Reg. § 20.2031-1). The appraisal should analyze the decedent’s ownership interest as it existed at that time, not after later family negotiations, redemptions, distributions, or management changes unless those later events reflect facts known or knowable at death.
Estate appraisals often require interim financial statements near the date of death. If a business owner dies in August, the latest annual tax return may not be enough. The analyst may need year-to-date income statements, balance sheets, backlog, accounts receivable aging, debt schedules, customer data, and management interviews to understand conditions on the valuation date.
Alternate valuation election caveat
IRC § 2032 provides a possible alternate valuation date election for estates that satisfy statutory requirements (26 U.S.C. § 2032). This article does not provide election advice. Whether an estate can or should use alternate valuation is a legal and tax decision requiring analysis by estate tax counsel and the CPA preparing Form 706. From a valuation perspective, if alternate valuation is elected, the appraiser must clearly identify the relevant date and facts used.
Practical timeline for ordering the appraisal
Do not wait until the return deadline is days away. A credible business valuation requires document collection, management questions, normalization analysis, method selection, review of agreements, discount support, report writing, and advisor review. Forms 706 and 709 and their instructions change over time, and filing deadlines or extensions should be managed by tax professionals (IRS, 2025a, 2025b, 2025c, 2025d).
| Issue | Gift valuation | Estate valuation |
|---|---|---|
| Typical valuation date | Date of completed gift | Date of death, unless alternate valuation is validly elected |
| Return | Form 709 may be required depending on facts | Form 706 may be required depending on estate facts |
| Key documents | Transfer assignment, trust records, entity agreement | Date-of-death ownership records, estate inventory, entity agreement |
| Appraisal focus | Transferred interest and adequate disclosure support | Interest included in gross estate and return support |
| Advisor coordination | Estate planner, CPA, valuation analyst | Executor, estate attorney, CPA, valuation analyst |
When a Business Valuation Is Commonly Needed
Gifts of LLC, partnership, S corporation, or C corporation interests
A valuation is commonly needed when an owner gifts interests in a closely held company to children, trusts, family limited partnerships, grantor trusts, or other related parties. Gift tax reporting may be required even if no current out-of-pocket gift tax is due because the transfer may use lifetime exemption or require adequate disclosure (IRS, n.d.-b; IRS, 2025c, 2025d). The valuation should match the transferred property: common stock, preferred stock, voting units, nonvoting units, general or limited partnership interests, or another class.
Estate owns closely held company interests
If a decedent owned private company interests, the executor may need a business appraisal for estate tax reporting, fiduciary administration, and family allocation. Closely held business interests may appear on Form 706 schedules and should be supported by enough information to demonstrate fair market value (IRS, 2025a, 2025b). The estate’s value may depend on control rights, restrictions, company prospects, debt, liquidity, and whether the interest can compel distributions or sale.
Intra-family sales, bargain sales, recapitalizations, and freezes
Valuation is also important for sales to grantor trusts, installment sales, preferred-equity freezes, recapitalizations, redemptions, and other planning transactions. If property is transferred for less than adequate and full consideration, the excess may be treated as a gift (26 U.S.C. § 2512). The valuation report helps advisors determine whether the transfer price is supportable and how the transaction should be disclosed.
Buy-sell agreements and formula prices
A buy-sell agreement may be highly relevant, but it does not automatically control gift or estate tax value. IRC § 2703 provides that certain options, agreements, rights, or restrictions may be disregarded unless requirements are met, and the regulations provide additional detail (26 U.S.C. § 2703; Treas. Reg. § 25.2703-1). A formula price based on book value, stale earnings, or an outdated certificate can be problematic if it does not reflect fair market value or if the agreement fails legal scrutiny.
Asset-heavy holding companies and family limited partnerships
Family limited partnerships, real estate holding companies, investment entities, and asset-heavy operating companies often require a strong asset approach. The appraiser may analyze net asset value, real estate appraisals, marketable securities, liabilities, built-in gains, control rights, restrictions, expected holding period, and marketability. Estate of Richmond illustrates how built-in gains and investment-company valuation issues can become central in a Tax Court dispute (Estate of Richmond v. Commissioner, 2014).
What the IRS Expects to See in a Defensible Business Appraisal
Clear identification of property, interest, owner, and valuation date
A defensible report begins with the basics: entity name, legal form, owner, percentage interest, class of equity, voting rights, distribution rights, transfer restrictions, valuation date, purpose, standard of value, premise of value, and intended use. The valuation should not say merely “value of ABC Company.” It should say, for example, “fair market value of a 20% noncontrolling, nonmarketable Class B nonvoting membership interest in ABC Holdings, LLC as of December 31, 2026, for federal gift tax reporting support.”
This level of specificity also helps with adequate disclosure for gift tax purposes. Treasury Regulation § 301.6501(c)-1 identifies categories of information relevant to adequate disclosure, including descriptions of transferred property, relationships of the parties, valuation methods, and certain appraisal information (Treas. Reg. § 301.6501(c)-1). The exact filing package should be determined by tax advisors.
Appraiser qualifications and independence
The IRS does not accept a valuation just because it has a professional-looking cover page. The analyst should have relevant training, experience, credentials, and independence for the assignment. A valuation of a manufacturing company with complex owner compensation issues differs from a valuation of a family limited partnership holding marketable securities. AICPA SSVS No. 1, USPAP, and NACVA standards all emphasize competency, scope, documentation, and reporting discipline (AICPA, 2007; NACVA, n.d.; The Appraisal Foundation, 2024).
Independence and objectivity matter. A report prepared to justify a preselected value is vulnerable. The analyst should be able to explain the data reviewed, assumptions made, limitations encountered, methods considered, and reasons for the conclusion.
Company and industry analysis
Revenue Ruling 59-60 directs attention to the nature and history of the business and the economic outlook for the company and its industry (IRS, 1959). A report should explain what the company does, how it makes money, its customers, suppliers, competition, management team, geographic market, regulatory environment, and growth prospects. For a professional-services firm, key-person and referral-source risk may dominate. For a construction company, backlog and work-in-process may be critical. For a holding company, asset values and liquidity may matter more than operating EBITDA.
Financial statement analysis and normalization
A credible business valuation usually analyzes several years of financial statements, tax returns, interim results, and balance sheets. The analyst may normalize revenue, margins, owner compensation, related-party rent, nonrecurring expenses, discretionary expenses, unusual litigation, PPP-style nonrecurring items if relevant to the period, and other items that distort economic earnings. EBITDA can be useful for operating companies, but EBITDA is not a valuation conclusion. It is one possible earnings measure that must be interpreted in context.
The IRS reasonable compensation job aid is not binding authority, but it illustrates the importance of analyzing owner compensation with evidence rather than arbitrary add-backs (IRS Large Business and International Division [IRS LB&I], 2014b). For transfer-tax valuation, compensation normalization can materially affect income approach calculations, market approach comparability, and the perceived risk of the business.
Valuation approaches and method selection
The report should discuss the valuation methods considered and explain why each was used or rejected. The three broad valuation approaches are the income approach, market approach, and asset approach. A discounted cash flow analysis may be appropriate for a company with forecastable future cash flows; a capitalization of earnings method may fit stable normalized earnings; a market approach may help when comparable public companies or transactions are sufficiently similar; and an asset approach may be central for holding companies or asset-heavy entities (AICPA, 2007; IRS, 1959).
No single approach is required for every company. The IRS and courts scrutinize unsupported method choices, mechanical weighting, and conclusions that ignore contrary evidence. Estate of Giustina is a useful reminder that method weighting should reflect likely economic reality and the specific facts (Estate of Giustina v. Commissioner, 2014).
Discount analysis and empirical support
Discounts are often the most contested part of gift and estate tax business valuations. A lack of control discount may be relevant when the owner cannot direct distributions, management, sale, liquidation, or financing. A discount for lack of marketability may be relevant when there is no ready market and transfer is restricted. Built-in gains, key-person risk, customer concentration, and company-specific risk may also affect value, but they must be handled without double-counting.
Do not assume a generic discount percentage. The IRS DLOM job aid, while non-authoritative, describes the types of evidence valuation professionals consider, including restrictions, expected holding period, dividends, volatility, empirical studies, and option models (IRS LB&I, 2009). Mandelbaum is frequently cited for marketability-discount factors, but it should not be treated as a formula or a safe harbor (Mandelbaum v. Commissioner, 1995). Revenue Ruling 93-12 supports the idea that family ownership alone does not automatically eliminate minority-interest analysis in the gift context addressed, but it does not guarantee discounts (IRS, 1993).
Reconciliation and sensitivity
The valuation conclusion should reconcile all methods used. If the income approach indicates one value and the market approach another, the analyst should explain the difference. If the asset approach is rejected, the report should say why. If projections are used, sensitivity analysis may help explain how changes in growth, margin, discount rate, terminal value, or working capital affect the conclusion. A defensible report reads like analysis, not advocacy.
| Component | Why it matters | Common weakness |
|---|---|---|
| Interest identification | Determines rights and discounts | Valuing company instead of ownership block |
| Valuation date | Controls facts and financial data | Using stale or post-date information improperly |
| Financial normalization | Converts accounting results to economic earnings | Arbitrary add-backs or ignored owner compensation |
| Method selection | Links facts to value conclusion | Blind use of EBITDA multiples |
| Discount support | Often challenged by IRS | Round-number discounts without evidence |
| Appraiser qualifications | Supports credibility and reasonable reliance | Inexperienced or conflicted analyst |
| Reconciliation | Shows judgment and reasonableness | Unsupported averaging or preselected value |
Applying the Main Valuation Methods
Income approach and discounted cash flow
The income approach values a business based on expected economic benefits. A discounted cash flow model estimates future cash flows and discounts them to present value using a rate that reflects risk. For gift and estate tax valuations, a DCF may be appropriate when management projections are available and can be evaluated. The analyst must test whether projections reflect valuation-date facts, not later optimism or hindsight.
DCF assumptions include revenue growth, margins, taxes, working capital, capital expenditures, debt-free or equity cash flow, terminal value, and discount rate. For an S corporation or partnership, the treatment of taxes and pass-through attributes can be complex. The IRS S corporation valuation job aid discusses the tax-affecting debate as a practice issue, and Estate of Jones shows that courts may consider tax-affecting and expert support based on the facts rather than applying a universal rule (Estate of Jones v. Commissioner, 2019; IRS LB&I, 2014a).
Example: suppose an estate owns 35% of a closely held S corporation with recurring revenue but heavy customer concentration. A DCF might be useful, but the analyst should evaluate whether projected growth is realistic, whether margins depend on the decedent’s personal relationships, whether customer concentration affects risk, and whether the 35% block can influence distributions or sale. The conclusion should not be a spreadsheet answer alone; it should be a reasoned fair market value opinion.
Capitalization of earnings
A capitalization of earnings method may be appropriate when normalized earnings are stable and expected to continue. The analyst estimates a representative earnings or cash-flow measure and capitalizes it at a rate reflecting risk and expected growth. This method can be simpler than a DCF, but it is not a shortcut. The normalized earnings base and capitalization rate must be supported.
For a mature professional-services company, normalized EBITDA or seller-level cash flow may require adjustment for owner compensation, nonrecurring expenses, and working capital. For a cyclical company, a single-year capitalization may be misleading. Revenue Ruling 59-60’s emphasis on earning capacity and financial condition helps frame the inquiry (IRS, 1959).
Market approach
The market approach uses evidence from guideline public companies or transactions involving comparable businesses. In transfer-tax valuation, market evidence can be persuasive when the comparables are truly comparable and the analyst adjusts for size, growth, margins, risk, capital structure, customer concentration, and control. It can be weak when the selected companies operate in different markets or when transaction data lacks detail.
EBITDA multiples are common in market approach analysis, but unsupported multiples are a red flag. A report should not say “private companies in this industry sell for X times EBITDA” without explaining the data source, comparability, adjustments, and relevance to the subject interest. Revenue Ruling 59-60 allows consideration of comparable public company market prices when meaningful, but it does not endorse blind multiple selection (IRS, 1959).
Asset approach
The asset approach values a company based on the value of its assets less liabilities, often adjusted to fair market value. It may be central for investment holding companies, family limited partnerships, real estate entities, asset-heavy businesses, or companies whose earnings do not adequately capture asset value. Asset approach work may require separate real estate appraisals, machinery and equipment appraisals, marketable securities schedules, debt analysis, and built-in gains analysis.
Estate of Richmond highlights that built-in capital gains tax and investment-company valuation can be contentious (Estate of Richmond v. Commissioner, 2014). The analyst should not mechanically subtract every potential tax liability or ignore it entirely. The treatment depends on the facts, applicable law, and market-participant assumptions.
Why weighting matters
Some valuations use multiple approaches and weight them. Weighting should not be arbitrary. A 50/50 average of income and asset values may be inappropriate if one method is far more reliable. Estate of Giustina demonstrates that courts can reject method weighting when it implies an economic outcome not supported by evidence, such as overemphasizing liquidation when liquidation is unlikely (Estate of Giustina v. Commissioner, 2014).
| Method | Best-fit fact pattern | Data needed | IRS/court scrutiny point | Avoid |
|---|---|---|---|---|
| Discounted cash flow | Forecastable operating business | Projections, margins, capex, working capital, risk data | Hindsight and unsupported projections | Spreadsheet with no narrative support |
| Capitalization of earnings | Stable earnings business | Normalized cash flow and capitalization rate | Whether earnings are truly representative | One-year earnings without adjustment |
| Market approach | Comparable companies or deals exist | Reliable guideline data and adjustments | Comparability and multiple support | Unsupported EBITDA multiples |
| Asset approach | Holding or asset-heavy entity | Fair values of assets and liabilities | Built-in gains, control, liquidation premise | Book value as automatic FMV |
Discounts and Special Transfer-Tax Valuation Issues
Lack of control or minority interest discounts
A noncontrolling interest may be worth less than its pro rata share of the total company because it cannot force dividends, hire or fire management, sell assets, amend agreements, redeem units, or control financing. Whether a lack of control discount applies depends on the legal rights and facts. Revenue Ruling 93-12 is often cited because it rejected automatic family aggregation in the gift-tax situation addressed, but it does not mean every family transfer receives a discount (IRS, 1993).
The appraiser should examine voting rights, board or manager control, distribution history, veto rights, transfer provisions, drag-along or tag-along rights, and state-law rights. The report should distinguish lack of control from lack of marketability and avoid double-counting.
Discount for lack of marketability
DLOM reflects the economic difference between an interest that can be sold quickly in an active market and an interest that may be difficult, costly, or restricted to sell. Private company interests often lack marketability, but the amount must be supported. Relevant evidence may include transfer restrictions, expected holding period, distribution policy, redemption rights, company risk, volatility, size, leverage, financial transparency, and empirical marketability studies or models.
The IRS DLOM job aid is explicitly not authority for legal positions, but it is useful in understanding the analytical issues IRS valuation professionals may consider (IRS, n.d.-c; IRS LB&I, 2009). Mandelbaum is often cited for DLOM factors, including financial statement analysis, dividend policy, company outlook, management, control, restrictions, holding period, redemption policy, and costs associated with public offering (Mandelbaum v. Commissioner, 1995). The practical lesson is simple: support the discount; do not guess it.
Built-in capital gains and tax liabilities
Asset-holding companies may own appreciated assets. A hypothetical buyer may consider embedded tax liabilities, but the treatment is fact-sensitive. Estate of Richmond involved a closely held investment company and built-in gains issues, illustrating that the tax effect can become central in litigation (Estate of Richmond v. Commissioner, 2014). The valuation should explain whether built-in gains are reflected in asset values, discounts, cash flows, or a separate adjustment, and why that treatment matches market-participant economics.
S corporation and pass-through tax-affecting
S corporation and partnership valuations raise questions about tax-affecting cash flows and pass-through attributes. There is no universal answer suitable for every valuation. Some analyses tax-affect earnings to improve comparability with C corporation data or to model owner-level economics; others do not. The IRS S corporation valuation job aid and Estate of Jones support a fact-sensitive approach focused on economic reality and expert support (Estate of Jones v. Commissioner, 2019; IRS LB&I, 2014a). The report should explain the chosen treatment and avoid pretending the issue is settled by a slogan.
Key-person, customer concentration, and company-specific risk
A family business may depend heavily on one owner, one customer, one supplier, one license, or one location. These risks can affect projected cash flows, discount rates, market multiples, or specific adjustments. The analyst must avoid double-counting. For example, if a DCF already reduces projected revenue for likely customer attrition after the owner’s death, adding a separate key-person discount for the same risk may overstate the adjustment.
Buy-sell agreements, options, restrictions, and IRC § 2703
Buy-sell agreements can reduce disputes among owners, but transfer-tax value may require additional analysis. IRC § 2703 and Treas. Reg. § 25.2703-1 address when certain options, agreements, rights, or restrictions may be disregarded for estate and gift tax valuation (26 U.S.C. § 2703; Treas. Reg. § 25.2703-1). A formula that has not been updated in years, or an agreement created primarily for intra-family transfer-tax reduction, may be challenged. Legal counsel should evaluate whether the agreement is relevant, binding, comparable to arm’s-length arrangements, and respected for tax purposes.
| Issue | What it means | Evidence needed | Weak support/red flag |
|---|---|---|---|
| Lack of control | Interest cannot direct company actions | Voting rights, agreements, distribution history | Applying discount without reading agreement |
| DLOM | Interest cannot be readily sold | Restrictions, holding period, dividends, risk, studies | Generic percentage with no support |
| Built-in gains | Assets carry embedded tax | Asset schedules, tax basis, sale assumptions | Automatic full deduction or total disregard |
| S corporation tax-affecting | Treatment of pass-through earnings | Case law, market data, cash-flow model | Universal rule with no facts |
| Key-person risk | Dependence on owner/manager | Management depth, client relationships | Double-counting in cash flow and discount rate |
| Buy-sell restrictions | Agreement may influence value | Agreement terms and § 2703 review | Blindly using book value formula |
Adequate Disclosure for Gift Tax Returns and Valuation Attachments
Why adequate disclosure matters
For gifts, adequate disclosure can be important because it may start the statute of limitations on gift valuation issues. Treasury Regulation § 301.6501(c)-1 describes disclosure requirements and valuation-related information that may be necessary (Treas. Reg. § 301.6501(c)-1). If a gift is not adequately disclosed, the IRS may have a longer period to challenge the valuation. This is a tax-return issue, so the CPA or attorney preparing Form 709 should decide the final disclosure package.
Information a robust Form 709 valuation package often includes
A strong gift tax package often includes a detailed description of the transferred business interest, the identity and relationship of transferor and transferee, entity governing documents, financial statements, appraiser report, valuation date, valuation methods, assumptions, restrictions, discounts, and supporting schedules. Form 709 and its instructions provide reporting structure, while the regulation supplies the adequate-disclosure framework (IRS, 2025c, 2025d; Treas. Reg. § 301.6501(c)-1).
The business appraisal should be written so the return preparer can extract the relevant facts. A one-page letter that states a value without explaining methods, documents, and assumptions may not be enough for robust disclosure.
What not to do
Do not attach a bare spreadsheet, a family-agreed number, a stale book-value certificate, or an unexplained discount schedule and assume the gift is protected. Do not omit related-party relationships. Do not hide restrictions, pending transactions, or prior offers. Do not use a valuation date that does not match the actual transfer. And do not treat a professional report as a substitute for proper return preparation.
| Item | Thin disclosure | Stronger disclosure |
|---|---|---|
| Property description | ”LLC units” | Percentage, class, voting rights, restrictions, entity name |
| Valuation date | Missing or vague | Exact gift date tied to transfer documents |
| Method support | ”Appraised value” | Income, market, and/or asset approach explanation |
| Discounts | Round-number deduction | Evidence-based lack of control and DLOM analysis |
| Appraiser | Name only | Qualifications, independence, report date, scope |
| Documents | None | Operating agreement, financials, cap table, transfer instrument |
Estate Tax Reporting and Form 706 Valuation Support
Business interests on an estate tax return
Form 706 is used for federal estate and generation-skipping transfer tax reporting where required. Closely held business interests, partnership interests, LLC units, and corporate stock may need detailed support and attachments (IRS, 2025a, 2025b). The valuation report should help the executor demonstrate how the reported fair market value was determined.
Executor and advisor workflow
Executors should gather the decedent’s ownership records, stock ledgers, operating agreements, buy-sell agreements, tax returns, financial statements, interim financials, debt schedules, appraisals of underlying assets, prior offers, prior transactions, life insurance or redemption arrangements, and any pending sale discussions. The appraiser should know whether the decedent had control, whether restrictions existed, whether there were related-party arrangements, and whether any post-death events are relevant to valuation-date facts.
Estate audit concerns
In estate audits, valuation issues may include discounts, control rights, method weighting, comparable-company selection, tax-affecting, related-party agreements, built-in gains, customer concentration, and reasonableness of appraiser reliance. Revenue Ruling 59-60, professional standards, IRS job aids, and case law all point toward the same defense strategy: a careful report that explains what was known, what was analyzed, what methods were used, and why the conclusion is reasonable (AICPA, 2007; IRS, 1959; IRS LB&I, 2009).
Common IRS Challenge Areas and How to Reduce Risk
Unsupported discounts
The fastest way to invite scrutiny is to apply a large discount without support. Discounts should be tied to rights, restrictions, empirical data, market behavior, expected holding period, distributions, risk, and the specific interest. The IRS DLOM job aid and Mandelbaum factors are useful reminders that marketability analysis is multifactorial, not a single percentage (IRS LB&I, 2009; Mandelbaum v. Commissioner, 1995).
Stale financials and missing normalization
A valuation based only on last year’s tax return may miss current performance, unusual expenses, owner compensation issues, debt changes, or major customer losses. Interim financial statements and normalization schedules are often necessary. The IRS reasonable compensation job aid underscores that compensation analysis should be fact-based (IRS LB&I, 2014b).
Overreliance on EBITDA multiples
EBITDA is useful but limited. It ignores capital expenditures, working capital, taxes, debt structure, and company-specific risk. A market approach using EBITDA multiples must explain comparability. An income approach using EBITDA as a starting point must convert earnings into appropriate cash flow. Unsupported multiples violate the discipline of both Rev. Rul. 59-60 and professional valuation practice (AICPA, 2007; IRS, 1959).
Ignoring agreements and restrictions—or blindly following them
Entity agreements can materially affect value, but they must be analyzed. Ignoring transfer restrictions is risky; blindly accepting a book-value formula is also risky. IRC § 2703 and Treas. Reg. § 25.2703-1 require legal review of certain agreements and restrictions in the transfer-tax context (26 U.S.C. § 2703; Treas. Reg. § 25.2703-1).
Inadequate appraiser qualifications or conflicts
A report prepared by someone without relevant business valuation experience may be vulnerable. So is a report prepared by an advocate who simply confirms the client’s desired number. Competency, independence, scope, and documentation are central under AICPA, USPAP, and NACVA standards (AICPA, 2007; NACVA, n.d.; The Appraisal Foundation, 2024).
Penalties and reasonable cause
IRC § 6662 can impose accuracy-related penalties, including valuation-related penalties, while IRC § 6664 provides reasonable-cause and good-faith concepts (26 U.S.C. §§ 6662, 6664). Estate of Richmond illustrates that reliance and valuation support can be scrutinized in penalty contexts (Estate of Richmond v. Commissioner, 2014). A credible appraisal may help, but it is not automatic protection.
| Red flag | Why risky | Better practice |
|---|---|---|
| Book value used as FMV | Book value may not reflect earnings, assets, or rights | Obtain fair market value business appraisal |
| Round-number discount | Looks unsupported | Document lack of control and DLOM evidence |
| Stale financials | Misses valuation-date facts | Use interim and trailing data where relevant |
| Blind EBITDA multiple | Ignores comparability | Explain market data and adjustments |
| Ignored buy-sell agreement | May omit relevant rights | Analyze agreement and § 2703 issues with counsel |
| Conflicted appraiser | Weakens credibility | Use qualified, independent valuation professional |
Practical Examples and Mini Case Studies
Example 1: Gift of a 20% minority LLC interest to a trust
A parent owns 100% of an operating LLC and gifts a 20% nonvoting membership interest to an irrevocable trust. The appraisal should not start and stop with 20% of total company value. It should examine the operating agreement, voting provisions, transfer restrictions, distribution history, financial performance, owner compensation, customer concentration, and marketability. The analyst may use an income approach, market approach, or both, depending on the data. Any lack of control or marketability discount should be supported by the facts and empirical analysis, not a generic percentage.
For Form 709 support, the return preparer may need the appraisal, transfer documents, description of the interest, relationship of the parties, valuation methods, restrictions, and discount explanation. Adequate disclosure is a filing issue under Treas. Reg. § 301.6501(c)-1, so the valuation team should coordinate with tax counsel and the CPA.
Example 2: Estate owns 35% of a closely held S corporation
A decedent owned 35% of a family S corporation. The valuation date is the date of death unless an alternate valuation election is properly made. The appraiser reviews historical financials, interim results, customer concentration, management continuity after the decedent’s death, shareholder agreement terms, distribution history, and whether the 35% block can influence major decisions. A discounted cash flow analysis may be useful if projections are reliable, but the analyst must avoid hindsight. Tax-affecting should be addressed carefully if it is relevant to the chosen methodology, with clear support rather than a universal assumption.
Example 3: Family limited partnership holding real estate and securities
An estate includes a limited partnership interest in a family entity that owns real estate and marketable securities. The asset approach may be central because asset values drive economics. The appraiser may rely on real estate appraisals, brokerage statements, debt schedules, and tax-basis information. Discounts may be considered for lack of control and lack of marketability, but they must reflect the partnership agreement, distribution policy, expected holding period, asset liquidity, and market evidence. Built-in gains may require careful analysis.
Example 4: Outdated buy-sell agreement value
A shareholder agreement says shares are valued at book value, but the value was last updated five years ago. The company has since grown substantially and accumulated valuable intangible assets. For gift or estate tax purposes, the formula price may not be enough. Counsel should evaluate IRC § 2703 and the agreement’s enforceability and tax relevance. The appraiser should still perform a fair market value analysis based on the specific interest, current company facts, and valuation date.
Owner and Advisor Checklist Before Ordering a Valuation
Documents to gather
A smooth valuation engagement starts with document readiness. Owners, executors, trustees, and advisors should gather tax returns, financial statements, interim statements, general ledger detail, ownership records, stock ledgers, operating agreements, shareholder agreements, partnership agreements, buy-sell agreements, prior appraisals, prior transactions, offers, debt schedules, lease documents, customer concentration reports, budgets, projections, compensation data, and descriptions of nonrecurring events. The analyst may ask for more after reviewing the initial package.
Questions to answer before engagement
Before hiring a valuation professional, answer these questions:
- What exact interest is being valued?
- What is the valuation date?
- Is the assignment for a gift, estate, planning transaction, audit, or litigation support?
- What return deadline or extension applies?
- Are there related-party transfers or agreements?
- Are there transfer restrictions or buy-sell provisions?
- Have there been prior offers, sales, redemptions, or appraisals?
- Are projections available, and were they prepared before the valuation date?
- Who will use the report?
- What level of report is needed for tax support?

Key Takeaways
An IRS-ready gift or estate tax business valuation is a fair market value opinion for a specific ownership interest on a specific date. It should not rely on book value, a family-negotiated price, a stale agreement, or an unsupported EBITDA multiple. The report should identify the exact interest, apply appropriate valuation methods, analyze rights and restrictions, normalize financial information, support discounts, and reconcile the conclusion.
The most important source anchors are the Code and Treasury regulations for fair market value and valuation dates, Form 706 and Form 709 instructions for reporting context, Rev. Rul. 59-60 for closely held business valuation factors, Rev. Rul. 93-12 and § 2703 for family and agreement issues, professional standards for appraisal discipline, and case law for cautionary examples. Strong documentation does not guarantee IRS acceptance, but it materially improves the credibility of the taxpayer’s position.
FAQ
1. What is fair market value for gift and estate tax purposes?
Fair market value is generally the price at which property would change hands between a hypothetical willing buyer and willing seller, neither under compulsion and both having reasonable knowledge of relevant facts. Treasury regulations use this standard for both estate and gift tax valuation (Treas. Reg. §§ 20.2031-1, 25.2512-1).
2. Is book value acceptable for a gift or estate tax business valuation?
Book value alone is usually not enough for a closely held business valuation. It may be one factor, especially for asset-heavy entities, but fair market value also considers earning capacity, cash flows, intangible value, restrictions, control, marketability, and comparable evidence. Revenue Ruling 59-60 specifically discourages formula-only thinking by listing multiple valuation factors (IRS, 1959).
3. When do I need a valuation for Form 709?
A valuation is commonly needed when a taxpayer gifts closely held business interests, LLC units, partnership interests, or corporate shares and must support the value reported on a gift tax return. Whether Form 709 is required depends on the facts and current law, so consult a CPA or tax attorney. The valuation should support the transferred interest as of the gift date (26 U.S.C. § 2512; IRS, 2025c, 2025d).
4. What is adequate disclosure for a gift tax return?
Adequate disclosure refers to the information required to disclose a gift sufficiently for statute-of-limitations purposes. Treasury Regulation § 301.6501(c)-1 describes relevant information, including property description, parties, valuation methods, and appraisal details. A valuation report can support adequate disclosure, but the return preparer must decide the final filing package (Treas. Reg. § 301.6501(c)-1).
5. What valuation date applies for an estate tax appraisal?
The default estate valuation date is generally the date of death under IRC § 2031. An alternate valuation election may be available only if statutory requirements are met under IRC § 2032. Executors should consult estate tax counsel before making election decisions (26 U.S.C. §§ 2031, 2032).
6. Does the IRS require a discounted cash flow analysis?
Not for every business. A discounted cash flow analysis is one income approach method and may be appropriate when future cash flows can be reasonably projected. Other methods, including capitalization of earnings, market approach, and asset approach, may be more relevant depending on the facts. AICPA SSVS No. 1 and Rev. Rul. 59-60 support considering relevant methods rather than applying one mandatory method (AICPA, 2007; IRS, 1959).
7. Can minority and marketability discounts apply to family business interests?
They can apply when supported by the legal rights and economic facts. Revenue Ruling 93-12 indicates that family ownership alone should not automatically eliminate minority-interest analysis in the gift-tax context addressed, but discounts are not automatic. DLOM and lack of control require evidence and careful analysis (IRS, 1993; IRS LB&I, 2009).
8. Are there standard IRS discount percentages?
No. There are no universal safe-harbor discount percentages for private business interests. Discounts depend on control rights, transfer restrictions, expected holding period, distributions, company risk, market evidence, and legal facts. Generic round-number discounts are a common audit red flag.
9. Can a buy-sell agreement set the estate or gift tax value?
A buy-sell agreement may be relevant, but it does not automatically control value for transfer-tax purposes. IRC § 2703 and Treas. Reg. § 25.2703-1 can cause certain agreements or restrictions to be disregarded if requirements are not met. Legal counsel should review the agreement’s tax effect (26 U.S.C. § 2703; Treas. Reg. § 25.2703-1).
10. What happens if the IRS disagrees with the valuation?
The IRS may request support, propose adjustments, challenge discounts, question methods, or assert penalties depending on the facts. The taxpayer may need the appraiser, CPA, and attorney to defend the report. IRC §§ 6662 and 6664 address penalty and reasonable-cause concepts, but defenses are fact-specific (26 U.S.C. §§ 6662, 6664).
11. Should an S corporation valuation be tax-affected?
It depends. Tax-affecting pass-through entity earnings is a fact-sensitive valuation issue. Some analyses and cases support tax-affecting when properly explained; others may not. The report should explain the selected treatment, data, and rationale rather than assuming a universal rule (Estate of Jones v. Commissioner, 2019; IRS LB&I, 2014a).
12. What documents should I provide to a valuation analyst?
Provide tax returns, financial statements, interim financials, ownership records, entity agreements, buy-sell agreements, transfer documents, debt schedules, customer data, projections, prior appraisals, offers, and details about nonrecurring income or expenses. The appraiser may request additional data after reviewing the company and interest.
13. Does an appraisal guarantee the IRS will accept the value?
No. A professional appraisal improves documentation and credibility, but it does not guarantee IRS acceptance. The IRS can challenge assumptions, methods, discounts, or reporting. The goal is a well-supported, good-faith fair market value opinion that can be defended if reviewed.
14. How early should I order a business appraisal for gift or estate tax planning?
Order it early enough to gather documents, resolve entity-description issues, analyze financials, coordinate with advisors, and review the final report before filing deadlines. Last-minute valuations increase the risk of missing documents, weak disclosure, or errors in the valuation date and interest description.
