Why Estate Attorneys Should Require Certified Appraisals for Form 706

When an estate includes a privately held business interest, the Form 706 file should not rely on guesswork, book value, a stale buy-sell formula, or a quick “multiple of EBITDA” estimate. The estate tax return is built around supportable asset values, and a private company interest is usually one of the hardest assets in the estate to price. For estate attorneys, the practical answer is straightforward: when Form 706 involves a closely held corporation, LLC, partnership, family operating company, professional practice, holding company, or other private business interest, require a credentialed and well-documented business appraisal unless the facts clearly support a simpler route.

This article uses “certified appraisal” in the practical professional-services sense: a business valuation report prepared by a qualified valuation professional under recognized appraisal or valuation standards, with a clear valuation date, standard of value, purpose, subject interest, methods, assumptions, procedures, schedules, and conclusion. It does not mean that the IRS “certifies” the report, that the IRS has approved a particular appraiser, or that every Form 706 legally requires the same type of report in every situation. The point is risk control. Form 706 reporting, fair market value, estate administration, beneficiary communication, and possible IRS review all become easier to defend when the file contains a coherent, independent business appraisal rather than an unsupported number.

The federal estate tax framework starts with the gross estate under Internal Revenue Code section 2031, and Treasury Regulation section 20.2031-1 frames fair market value in terms of a hypothetical willing buyer and willing seller, neither under compulsion and both having reasonable knowledge of relevant facts (26 U.S.C. § 2031, n.d.; 26 C.F.R. § 20.2031-1, n.d.). Form 706 and its instructions provide the official reporting context for the United States Estate (and Generation-Skipping Transfer) Tax Return (Internal Revenue Service [IRS], n.d.-a, n.d.-b, n.d.-c). Those sources do not turn every private company value into a mechanical formula. They require careful valuation judgment. That is why estate counsel should build a process that gets the business valuation right before the return is filed.

For attorneys who need support on the valuation side, Simply Business Valuation provides professional business valuation and business appraisal reports for privately held company interests used in estate planning and estate administration support. Estate counsel and the estate’s CPA remain responsible for legal conclusions, filing positions, elections, attachments, beneficiary reporting, and tax advice. The appraiser’s role is to deliver a supportable value conclusion and the analysis behind it.

Quick Trigger Table: When Estate Counsel Should Require a Business Appraisal Before Filing Form 706

Estate fact pattern	Why the attorney should pause	Core valuation issue	Recommended action
Closely held corporation, LLC, partnership, or professional practice	No public market quotation usually exists	Fair market value must be developed from company facts, rights, restrictions, assets, and earnings	Engage a credentialed business valuation professional early
No recent arm’s-length sale of the exact interest	Management or family estimates may be biased or incomplete	Lack of market evidence increases judgment	Obtain a documented business appraisal rather than a verbal estimate
Buy-sell agreement price exists	Formula may be stale, incomplete, or designed for owner planning rather than estate tax reporting	Agreement terms may be relevant but may not answer the estate tax value question	Provide the agreement to the appraiser and have it analyzed
Minority or noncontrolling interest	The rights of the specific block affect value	Control, transferability, distributions, voting rights, and restrictions matter	Value the actual interest held by the decedent, not merely the whole company
Entity owns real estate, equipment, securities, or nonoperating assets	Enterprise value may not equal operating business value	Underlying assets may need separate appraisal or adjustment	Coordinate business appraisal with real estate/equipment specialists if material
Uneven earnings, owner compensation, related-party transactions, debt, or customer concentration	Tax returns and book income may not reflect normalized economics	Normalization and risk analysis are central	Require a full report explaining adjustments and assumptions
Alternate valuation election is being considered	Date discipline can affect values	Estate-tax election analysis must align with valuation evidence	Coordinate estate counsel, CPA, and appraiser before filing
Beneficiary basis reporting may be implicated	Reported estate values may affect later beneficiary reporting	Basis consistency issues may arise for certain estates	Coordinate valuation support with Form 8971 and Schedule A analysis if applicable

What Form 706 Does and Why Private Business Interests Deserve Special Treatment

Form 706 is the federal estate tax return used to report the estate of a decedent where filing is required and, when applicable, generation-skipping transfer tax matters (IRS, n.d.-a, n.d.-b). The form and instructions organize estate assets, deductions, tax computations, elections, and supporting schedules. The current instructions should always be checked because thresholds, procedural details, schedules, and IRS administrative guidance can change. The attorney’s job is not only to complete a form; it is to build a defensible estate administration file.

A bank account, brokerage statement, publicly traded stock, or quoted bond may have direct account documentation or market quotations. Even those assets must be reported correctly, but the valuation evidence is often readily observable. A private business interest is different. There may be no public price, no recent transaction, no independent buyer, and no single data point that captures the rights attached to the decedent’s interest. A 40% nonvoting interest in a family LLC is not the same asset as 100% of a company’s operating assets. A minority limited partnership interest is not the same as a controlling general partner position. A professional practice dependent on one owner’s labor is not the same as a diversified manufacturing business with recurring management depth.

Treasury Regulation section 20.2031-2 addresses valuation of stocks and bonds and is especially useful for understanding why quotations, unavailable market data, and closely held stock require careful analysis (26 C.F.R. § 20.2031-2, n.d.). The regulation is stock-focused, so attorneys should be careful not to force every LLC or partnership issue into language designed for corporate shares. Still, the principle is practical: when an asset does not have a reliable public quote, the estate needs a reasoned valuation process.

That is why a business appraisal should be part of the Form 706 workflow whenever a private company interest is material, complex, disputed, restricted, or hard to value. The report gives the attorney and preparer a documented basis for the value placed on the return. It also helps the executor explain the value to beneficiaries, coordinate basis matters with tax advisers, and respond if the IRS asks for support.

The Fair Market Value Foundation for Estate Business Valuation

The estate tax valuation foundation begins with the property included in the gross estate under section 2031 (26 U.S.C. § 2031, n.d.). For valuation purposes, Treasury Regulation section 20.2031-1 provides the familiar fair market value concept: the price at which property would change hands between a willing buyer and a willing seller when neither is under compulsion and both have reasonable knowledge of relevant facts (26 C.F.R. § 20.2031-1, n.d.). In a business valuation report for Form 706 support, that standard should be stated clearly and applied consistently.

Fair market value is not sentimental value to the family, liquidation panic value, book value, tax basis, or the executor’s preferred planning result. It is a market-based standard applied to the subject interest as of the correct valuation date. Attorneys should make sure the appraisal identifies the decedent, the estate, the subject company, the specific ownership interest, the purpose of the appraisal, the standard of value, and the valuation date.

The valuation date is especially important. The date-of-death value is generally the starting point, while section 2032 provides an alternate valuation framework when statutory requirements are met (26 U.S.C. § 2032, n.d.). This article does not provide election advice. The key point for estate attorneys is that the appraisal must match the estate’s filing position. If the estate is evaluating alternate valuation, counsel, the CPA, and the appraiser should coordinate before finalizing the report so the appraiser does not analyze the wrong date or omit relevant post-death facts that must be treated consistently with the election rules.

A good appraisal also distinguishes known facts as of the valuation date from hindsight. For example, if the company lost a major customer after death, the appraiser must determine whether the risk was known or reasonably knowable at the valuation date, whether it relates to an alternate valuation analysis, or whether it is post-valuation information that should not drive a date-of-death conclusion. Attorneys do not need to perform the appraisal, but they do need to verify that date discipline is visible in the report.

Why a Private Business Interest Is Not Just Another Estate Asset

No daily quote and limited comparable evidence

Private companies do not trade every day on a public exchange. Their shares or membership interests are often held by a small group of family members, employees, founders, or investors. Transfers may be restricted. Financial statements may be prepared for tax compliance rather than investor reporting. Management may be closely tied to the decedent or surviving family members. Comparable transaction data may exist, but it must be tested for relevance.

This is the first reason estate attorneys should require a business appraisal. Without an appraisal, the file may contain only a value typed into a schedule with little explanation. A professional report should explain what data was available, which valuation methods were considered, which were used, and why the conclusion is reasonable under the fair market value standard.

The actual interest matters

A valuation must address the exact interest owned by the decedent. A controlling voting interest may carry decision-making power, while a minority nonvoting interest may lack the ability to compel distributions, sell assets, change compensation, or direct company strategy. Partnership and LLC agreements may include transfer restrictions, rights of first refusal, buy-sell provisions, capital call obligations, distribution provisions, or special voting rules. Corporate shares may be voting or nonvoting, common or preferred, restricted or freely transferable.

The appraisal should not merely value “the company” and apply the decedent’s percentage mechanically unless that method is appropriate and fully explained. Often the report begins with an enterprise or equity value for the company, then bridges to the estate-owned interest by considering debt, nonoperating assets, ownership percentage, and interest-specific adjustments. Discounts for lack of control or lack of marketability are not automatic. They must be fact-specific, supported, and consistent with the rights and restrictions of the actual interest.

Entity documents may affect value but rarely replace a full appraisal

Operating agreements, shareholder agreements, partnership agreements, buy-sell agreements, amendments, option agreements, and prior transfer documents can be highly relevant. They may define transfer rights, identify formulas, restrict buyers, or create redemption rights. But those documents are not automatically a substitute for a full business appraisal. A formula created years ago for internal planning may not reflect current fair market value. A buy-sell price may have been designed for life insurance funding, owner disputes, or succession planning rather than estate tax reporting.

Estate attorneys should send all governing documents to the appraiser and ask the report to address them. If a buy-sell formula is used, the appraisal file should explain why it is relevant, how current it is, whether it was followed in practice, and whether it reflects the economics of the subject interest. If the formula is rejected or treated only as one data point, the report should explain that as well.

Company-specific adjustments can change the value conclusion

Business valuation is not just spreadsheet arithmetic. Private company financial statements often require normalization. The appraiser may examine owner compensation, related-party rent, discretionary expenses, nonrecurring income or expense, unusual legal costs, pandemic or disaster effects, debt, working capital, tax status, customer concentration, supplier risk, management depth, and nonoperating assets. Each adjustment must be supported by documents and explained in the report.

For example, EBITDA may be useful for understanding normalized operating performance, but EBITDA is not value by itself. A company with stable recurring revenue, low capital expenditure needs, strong management, and low customer concentration may be very different from a company with the same EBITDA but fragile revenue, owner dependence, high debt, and obsolete equipment. Attorneys should therefore reject unsupported “X times EBITDA” shortcuts and require a report that explains the company’s actual risk and cash flow.

Information asymmetry and fiduciary communication

Estate administration often involves parties who do not share the same information. The executor may rely on management. Beneficiaries may distrust management. A surviving owner may have incentives that differ from the estate. A CPA may see tax returns but not governance documents. The attorney must coordinate all of this while maintaining a defensible file. IRS Publication 559 provides general executor and administrator context, but it does not solve the private business valuation problem for a specific estate (IRS, n.d.-h). A professional appraisal helps create a common reference point: what was valued, what information was reviewed, what assumptions were made, and how the conclusion was reached.

What “Certified Appraisal” Should Mean in an Estate Attorney’s Workflow

A “certified appraisal” for this purpose should mean a written business appraisal prepared by a qualified valuation professional with appropriate credentials, experience, standards compliance, and independence for the assignment. The appraiser may hold credentials through organizations or professional bodies, and the report may reference standards such as NACVA Professional Standards, AICPA valuation services standards resources, or USPAP depending on the appraiser, credential, assignment scope, and professional obligations (AICPA-CIMA, n.d.; Appraisal Foundation, n.d.; National Association of Certified Valuators and Analysts [NACVA], n.d.). The exact standard framework should be identified in the report.

Attorneys should avoid loose language. The appraisal is not “IRS certified.” The IRS does not bless the number in advance simply because a credentialed professional prepared the report. A report can be challenged. A credential is evidence of training and professional accountability, not a guarantee. The value of the appraisal lies in the quality of the analysis, the sufficiency of the evidence, the fit between the methods and facts, and the appraiser’s ability to explain the conclusion.

A strong Form 706 support appraisal should usually include:

• Identity of the client and intended users, as appropriate for the engagement.
• Purpose of the appraisal and intended use in estate administration or Form 706 support.
• Subject company and specific ownership interest.
• Valuation date and report date.
• Standard of value, usually fair market value for estate tax reporting context.
• Premise of value if applicable.
• Company background, ownership, governance, and operating profile.
• Financial statement and tax return analysis.
• Normalization adjustments and support.
• Discussion of nonoperating assets, debt, working capital, and entity tax status.
• Analysis of ownership rights, restrictions, transferability, and control.
• Consideration of income, market, and asset approaches.
• Method selection and rejection rationale.
• Reconciliation of indications of value.
• Assumptions, limiting conditions, and appraiser certification.
• Exhibits and schedules sufficient for review.

For the estate attorney, the report is not just a number; it is a litigation-risk management, audit-readiness, fiduciary communication, and tax-compliance support document.

Method-Selection Matrix for Form 706 Private Company Appraisals

Valuation method	Best fit	Key inputs	Attorney review questions	Common risk controls
Income approach: discounted cash flow	Companies with forecastable future cash flows, meaningful projections, or changing performance	Revenue, margins, taxes, working capital, capital expenditures, terminal value assumptions, discount rate	Are projections consistent with facts known as of the valuation date? Are assumptions supported? Is customer concentration addressed?	Require clear forecast support, sensitivity discussion, and explanation of discount-rate risk factors
Income approach: capitalized earnings or EBITDA-based analysis	Stable companies where normalized current earnings reasonably indicate future performance	Normalized EBITDA or earnings, capitalization rate, growth, tax and reinvestment assumptions	Are owner compensation, related-party expenses, nonrecurring items, and debt handled correctly?	Reject unsupported rule-of-thumb multiples; require normalization schedules
Market approach	Companies with relevant guideline transaction or public-company evidence	Comparable company or transaction data, adjustments for size, growth, margin, risk, control, and marketability	Are comparables genuinely comparable? Are data sources identified? Are differences adjusted or explained?	Do not accept unexplained market multiples; require source transparency and reconciliation
Asset approach: adjusted net asset method	Holding companies, asset-intensive businesses, real-estate-heavy entities, or companies where assets drive value more than earnings	Adjusted assets and liabilities, real estate or equipment appraisals, debt, contingent liabilities	Are underlying assets separately appraised where needed? Are operating and nonoperating assets separated?	Coordinate specialists for real estate/equipment; avoid assuming book value equals fair market value
Reconciliation	Any assignment using multiple indications	Method indications, weights or qualitative emphasis, final checks	Does the conclusion explain why one method is more reliable than another?	Avoid mechanical averaging; require a reasoned final conclusion

Valuation Methods Attorneys Should Understand Without Becoming Appraisers

Income approach and discounted cash flow

The income approach values a business based on economic benefits expected from ownership. A discounted cash flow method converts expected future cash flows into present value using a supportable discount rate. It can be useful when the company has documented forecasts, predictable operations, or changing expected performance. In a Form 706 setting, the DCF must be tied to information known or reasonably knowable as of the valuation date, unless the assignment specifically addresses an alternate valuation date or other permitted analysis.

Estate attorneys should not try to build the DCF model themselves. Instead, they should review whether the report explains the forecast period, revenue assumptions, margin assumptions, working capital needs, capital expenditures, tax treatment, terminal value, and discount rate. If the report simply states a discount rate without explaining company risk, industry risk, size, leverage, dependence on owners, and cash-flow volatility, the attorney should ask questions. If management’s projections appear optimistic because surviving owners want a higher value or pessimistic because buyers want a lower value, the appraiser should address that bias.

EBITDA and capitalized earnings methods

EBITDA is often discussed in private company valuation because it approximates earnings before interest, taxes, depreciation, and amortization. It can help compare operating performance before financing structure and certain accounting charges. But EBITDA is not the same as cash flow, and it is not a substitute for professional judgment. A capitalized earnings method or EBITDA-based analysis must consider normalization, growth, risk, capital expenditure needs, working capital needs, taxes, debt, and the specific ownership interest.

Attorneys should focus on the adjustments. Did the appraiser normalize owner compensation? Did the report adjust related-party rent to market terms if supported? Did it remove nonrecurring income or expense? Did it account for discretionary personal expenses that ran through the business? Did it address whether the decedent’s services were essential to revenue? A company that loses key relationships when the decedent dies may have different risk than a company with a deep management team.

The report should avoid unsupported “rule-of-thumb” multiples. If a market multiple is used, it should be sourced, explained, adjusted, and reconciled. For this reason, estate counsel should not accept a one-page calculation that says “business equals five times EBITDA” without source support and method analysis.

Market approach

The market approach uses pricing evidence from transactions or companies that are sufficiently comparable to the subject company. In theory, this is attractive because fair market value is a market concept. In practice, private company data can be thin, inconsistent, or not comparable. The subject company may be smaller, riskier, more owner-dependent, more leveraged, less diversified, or less profitable than the companies in a database. A transaction may represent a controlling interest, while the estate owns a minority interest. A public-company multiple may reflect liquidity and scale that the subject company does not have.

A professional appraisal should identify the source of market data, explain selection criteria, discuss differences, and reconcile market indications with other valuation methods. The attorney’s review should focus on comparability, not just the final number. If the appraiser cannot explain why selected transactions are relevant, the market approach may be weak.

Asset approach

The asset approach values a business by reference to the fair value of its assets and liabilities. It can be especially relevant for holding companies, real-estate-heavy entities, investment entities, asset-intensive operating businesses, or companies whose earnings do not adequately capture asset value. For an operating company, the asset approach may be less relevant if value is driven primarily by going-concern earnings, but it should still be considered where material assets exist.

Attorneys should watch for a common mistake: assuming book value equals fair market value. Book value may reflect historical cost, depreciation, tax accounting, or accounting policies rather than current fair market value. Real estate, specialized equipment, securities, intangible assets, contingent liabilities, and debt may need separate analysis. A business appraiser may rely on real estate or equipment appraisals prepared by other specialists; the scope should be clear. A business valuation report does not automatically appraise every underlying asset unless the engagement includes that work or appropriate specialist reports are obtained.

Reconciliation

A credible business appraisal reconciles indications of value rather than averaging them mechanically. One method may be more reliable than another. An income approach may dominate for a stable operating company. An asset approach may dominate for a holding company. A market approach may be supportive but limited if comparables are weak. The final conclusion should explain the appraiser’s reasoning in plain enough language that the attorney, CPA, executor, and possibly an IRS reviewer can follow it.

Enterprise-to-Estate-Interest Value Bridge

The following placeholder bridge illustrates the logic attorneys should expect to see when a report moves from company-level value to the value of the estate-owned interest. It is not a formula for every case, and it does not supply valuation multiples or discount percentages.

Indicated enterprise value from selected valuation methods        $[A]
Less: interest-bearing debt                                      ([B])
Plus: excess cash / nonoperating assets                           [C]
Equals: indicated equity value                                    [D]
Estate-owned ownership percentage                                 [E%]
Preliminary pro rata value                                        [D x E%]
Adjustments for characteristics of the specific interest,
  if supported by rights, restrictions, control, and marketability [F]
Indicated value of estate-owned business interest                 [G]

The key phrase is “if supported.” Discounts and adjustments are not automatic decorations added at the end of a report. They must reflect the subject interest, governing documents, market evidence, cash-flow rights, control rights, transfer restrictions, and facts as of the valuation date. Attorneys should ask the appraiser to explain the evidence, not merely the arithmetic.

Attorney Risk Management: Why Requiring a Professional Appraisal Helps the File

Audit readiness

A professional appraisal does not guarantee IRS acceptance, but it gives the estate a structured explanation of the value reported. The report can show what documents were reviewed, how the company was analyzed, which methods were considered, why certain methods were rejected, how adjustments were made, and why the final conclusion is reasonable. That is far stronger than an unsupported figure in a workpaper.

If the IRS requests support, estate counsel wants the file to show that the executor used a professional process. The report should be complete enough that the reviewer can understand the path from documents to conclusion. It should not depend on unwritten assumptions, undocumented conversations, or missing schedules.

Penalty-risk context

The Internal Revenue Code includes accuracy-related penalty provisions, including rules that address valuation misstatements, and section 6695A addresses penalties for certain valuation misstatements attributable to incorrect appraisals (26 U.S.C. §§ 6662, 6695A, n.d.). This article does not provide penalty advice or compute penalty exposure. The practical point is that valuation quality matters. A thin or advocacy-driven valuation can create risk for the estate and, in some circumstances, for the appraiser. A robust appraisal can support the reasonableness of the estate’s process, but it is not a shield against all challenges.

Estate attorneys should therefore avoid pressuring appraisers for a predetermined number. A report that appears outcome-driven can undermine the very protection the estate hoped to create. The attorney’s role is to provide complete facts, ask review questions, and make sure the report matches the legal and filing context.

Beneficiary and basis consistency context

Valuation can affect more than estate tax. Section 1014 addresses basis of property acquired from a decedent, and section 6035 creates basis information reporting requirements for certain estates (26 U.S.C. §§ 1014, 6035, n.d.). IRS Form 8971 and its instructions provide official IRS materials for beneficiary basis information reporting where applicable (IRS, n.d.-d, n.d.-e, n.d.-f). Not every estate has the same reporting obligations, and this article does not decide whether Form 8971 applies to a particular estate. But when it does apply, the value analysis used in the estate tax file may affect later communications with beneficiaries and advisers.

A professional business appraisal helps the attorney and CPA maintain consistency. If the estate reports one value on Form 706 and later communicates another value for beneficiary purposes without explanation, questions can arise. Early coordination can reduce rework and confusion.

Fiduciary and beneficiary communication

Executors and trustees often need to explain estate asset values to beneficiaries who did not participate in the business. A professional report can reduce suspicion by showing that value was determined through a recognized process. It can also help beneficiaries understand why book value, tax basis, or the decedent’s informal estimate was not used. The report may not eliminate disputes, but it gives counsel a disciplined basis for discussion.

Risk Matrix: Shortcuts Estate Attorneys Should Not Accept

Shortcut	Why it is tempting	Why it can fail	Better evidence
Book value	Easy to find on balance sheet	May reflect historical cost, depreciation, or accounting policy rather than fair market value	Adjusted asset analysis and income/market methods where relevant
Tax basis	Available from tax records	Designed for tax accounting, not necessarily fair market value	Appraisal using fair market value standard
Owner’s estimate	Fast and inexpensive	May be biased, outdated, or unsupported	Independent business appraisal
Life insurance value	Often tied to buy-sell funding	May reflect funding needs, not current business value	Review buy-sell documents and perform valuation analysis
Loan collateral value	May come from lender underwriting	May be asset-specific, debt-focused, or outdated	Purpose-specific Form 706 support appraisal
Stale buy-sell price	Appears contractually convenient	Formula may not reflect current company facts or estate tax value	Analyze agreement as one input, not automatic answer
Prior financing valuation	May be recent and professional-looking	May value a different security, date, purpose, or investor rights	New appraisal for the estate-owned interest and valuation date
Unsupported rule-of-thumb multiple	Simple and familiar	Ignores company-specific risk, rights, and adjustments	Documented valuation methods and source-supported market evidence
CPA compilation or tax return alone	Already in the file	Financial reporting is not the same as valuation	Use financials as inputs to professional valuation

Practical Workflow: From Intake to Final Form 706 Support

Step 1: Identify business interests during estate intake

At the first estate administration meeting, ask specifically about corporations, LLCs, partnerships, professional practices, farms, family limited partnerships, investment entities, holding companies, franchises, side businesses, and any business in which the decedent had voting, nonvoting, profits, capital, debt, option, or contractual rights. Do not rely only on tax returns. Entity interests may appear in personal records, K-1s, shareholder agreements, operating agreements, minute books, buy-sell agreements, or family office schedules.

Step 2: Confirm entity type, ownership, rights, and valuation date

The appraiser needs to know exactly what is being valued. A 25% voting common stock interest is different from a 25% nonvoting interest. A limited partnership interest is different from a general partner interest. An LLC profits interest may be different from a capital interest. The valuation date must be identified, and any alternate valuation analysis must be coordinated with counsel and the CPA.

Step 3: Decide whether a professional business appraisal is needed

For private company interests, the default answer should usually be yes. Exceptions may exist for immaterial interests, interests with a clearly documented arm’s-length sale at or near the valuation date, or other facts where counsel and the CPA conclude that a full report is unnecessary. But because private interests are hard to value and can affect tax, basis, and beneficiary communications, requiring a professional appraisal is usually the safer practice.

Step 4: Collect documents before the appraiser starts

A delayed appraisal is often caused by incomplete documents. Estate counsel can improve the process by building a document request immediately. Common documents include tax returns, financial statements, interim financials, general ledger detail for key adjustments, entity agreements, buy-sell agreements, cap tables, debt schedules, leases, fixed asset lists, customer and vendor concentration data, management organization charts, prior appraisals, offers, transactions, and real estate or equipment appraisals.

Step 5: Coordinate attorney, CPA, executor, company management, and appraiser

The appraiser needs facts. The CPA may understand tax accounting and entity history. Management may understand operations and forecasts. The executor may control records. The attorney must coordinate the process and protect legal strategy. Establish who can answer questions, who approves document release, and how draft factual questions will be handled.

Step 6: Review the draft for factual consistency

The attorney should not tell the appraiser what value to reach. But counsel should review the draft to make sure the subject interest, ownership percentage, valuation date, governing documents, purpose, assumptions, and known facts are correct. If a shareholder agreement is missing, if the report uses the wrong date, or if the report values 100% of the company when the estate owns a minority nonvoting interest, the issue should be fixed before finalization.

Step 7: Retain support for the return and audit file

The estate’s filing team should decide how to summarize, attach, or retain the appraisal based on current Form 706 instructions, preparer practice, and legal advice. Regardless of attachment decisions, the file should retain the final report, source documents, correspondence, and review notes. If the IRS asks questions later, the estate should not have to reconstruct the valuation process from memory.

Step 8: Coordinate basis and beneficiary reporting issues

If basis consistency or Form 8971 reporting is implicated, coordinate the appraisal conclusion with the CPA and estate counsel responsible for those filings and communications. The goal is not merely to file Form 706; it is to maintain consistent estate administration records.

How Estate Attorneys Should Review an Appraisal Before Relying on It

A business appraisal can be long, technical, and dense. Estate attorneys do not need to audit every calculation, but they should perform a structured review before allowing the report to support a Form 706 filing.

First, confirm identity and purpose. Does the report name the estate or appropriate client? Does it identify the decedent, the subject company, the exact ownership interest, the valuation date, and the intended use? Does it state the standard of value? If any of those elements are missing or inconsistent, the report may not fit the filing.

Second, review information considered. Does the report list tax returns, financial statements, entity documents, interviews, market data, and other materials? If important documents were unavailable, does the report disclose that limitation? If the report relies heavily on management representations, does it explain them?

Third, evaluate method selection. Does the report consider the income approach, market approach, and asset approach, or explain why a method is not applicable? Does it use discounted cash flow only when projections are supportable? Does it use EBITDA or capitalized earnings with documented normalization? Does it avoid unsupported market multiples? Does it address asset values where the company owns material real estate, equipment, or investments?

Fourth, review normalization adjustments. Owner compensation, related-party rent, personal expenses, one-time litigation, unusual gains or losses, nonrecurring revenue, and extraordinary expenses can materially affect value. The report should show the adjustment, source, and rationale.

Fifth, check ownership-interest analysis. Does the report value the specific interest held by the decedent? If discounts or other adjustments are applied, are they supported and explained? If no discounts are applied, does the report explain why? Does the ownership percentage reconcile to estate records?

Sixth, check date discipline. Does the report distinguish date-of-death facts from later developments? If alternate valuation is considered, does the report clearly identify the relevant date and assumptions? If subsequent events are discussed, are they used appropriately?

Seventh, evaluate assumptions and limiting conditions. Are they standard and reasonable, or do they undermine the conclusion? For example, if the report assumes all financial statements are accurate but the attorney knows major accounting issues exist, the assumption should be revisited.

Eighth, make sure the report conclusion can be used by the filing team. The final value should be clear, the subject interest should be clear, and the schedules should allow the CPA or return preparer to connect the report to the Form 706 workpapers.

Common Form 706 Business Valuation Fact Patterns and Mini Case Studies

Case study 1: Family operating company with owner-dependent earnings

Assume the decedent owned a noncontrolling interest in a family operating company. The company has steady revenue, but the decedent historically generated key customer relationships. Tax returns show owner compensation, related-party rent, and several expenses that may or may not be discretionary. A family member suggests using last year’s book value because it is easy to document.

This is exactly the kind of file where estate counsel should require a professional business valuation. Book value may ignore goodwill, risk, normalized earnings, customer concentration, and the economic impact of the decedent’s role. The appraiser may analyze normalized EBITDA, consider an income approach, review market evidence if reliable, and address whether the decedent’s death affected future cash flows. The report should also address the rights of the noncontrolling interest and any transfer restrictions.

Case study 2: Real-estate-heavy operating entity

Assume the decedent owned an interest in an LLC that operates a business and owns the building used by the business. The financial statements show real estate at depreciated historical cost. The company also has debt and related-party lease arrangements. Management suggests that the estate simply report the LLC’s tax basis capital account.

That shortcut may be unreliable. The real estate may have a fair market value far above or below book value. The operating business may have goodwill or may depend mainly on the real property. A business appraiser may need a separate real estate appraisal to adjust the balance sheet or to separate operating and nonoperating assets. Estate counsel should coordinate the business appraisal, real estate appraisal, CPA workpapers, and Form 706 reporting position.

Case study 3: Stale buy-sell agreement

Assume a shareholder agreement states that shares will be valued annually by agreement of the shareholders, but the last agreed value was set seven years before death. The company has grown, taken on debt, and changed its product mix. The surviving shareholders want the estate to use the stale value because it is written in the company records.

The agreement is relevant and should be reviewed, but the attorney should not automatically accept the stale number as the estate tax value. A professional appraisal can analyze the agreement, compare it to current company economics, and explain whether it is reliable, partially relevant, or not persuasive for fair market value. The attorney can then coordinate legal conclusions with valuation evidence.

Case study 4: Estate considering alternate valuation

Assume the company’s value declined after the date of death because of market conditions, loss of a contract, or an industry event. The executor asks whether the estate can use a lower value. Section 2032 provides an alternate valuation framework when requirements are met, but the election analysis is legal and tax-specific (26 U.S.C. § 2032, n.d.).

The valuation lesson is that the appraiser must know which date is being analyzed and what facts can be considered. Counsel and the CPA should decide whether alternate valuation is being evaluated, then coordinate the report scope accordingly. A report that mixes date-of-death and post-death facts without explanation can create confusion.

How Simply Business Valuation Can Help Estate Attorneys

Estate attorneys need valuation work that is clear, supportable, and practical for the filing team. Simply Business Valuation provides professional business valuation and business appraisal reports for private company interests used in estate planning and estate administration support. A well-prepared report can help counsel and CPAs document fair market value, evaluate valuation methods, understand normalized EBITDA, consider discounted cash flow when appropriate, review market approach evidence, analyze asset approach issues, and maintain a defensible business appraisal file.

SBV’s role is valuation support. Estate counsel and tax advisers determine whether Form 706 must be filed, which elections apply, how schedules should be completed, what should be attached, and whether Form 8971 or other reporting is required. The best workflow is collaborative: the attorney defines the estate administration and legal context, the CPA coordinates tax reporting, the executor provides authority and records, management answers company questions, and the valuation professional produces a supportable conclusion.

For private business interests, the earlier the appraiser is engaged, the better. Early engagement leaves time to request documents, identify missing entity agreements, coordinate specialist appraisals, resolve factual inconsistencies, and review the draft before filing deadlines become urgent.

Practical Drafting Language Estate Attorneys Can Use Internally

Estate firms can reduce inconsistency by adopting internal intake and review language. For example:

“If the estate includes an interest in a privately held corporation, LLC, partnership, professional practice, holding company, or other nonpublic business, the responsible attorney should evaluate whether a professional business appraisal is needed for Form 706 support. In most material or hard-to-value cases, the firm should request a credentialed appraisal that identifies the subject interest, valuation date, fair market value standard, documents reviewed, methods considered, assumptions, limiting conditions, and conclusion.”

The policy should also say what not to use as a default value: book value, tax basis, owner estimate, insurance amount, stale buy-sell formula, unsupported EBITDA multiple, or lender collateral value. Those data points may be relevant, but they should not control the Form 706 file without analysis.

FAQ: Certified Appraisals, Form 706, and Private Business Interests

1. Does the IRS require a certified appraisal for every Form 706?

No. This article does not claim that every Form 706 requires a “certified appraisal” in all circumstances. The better practice is to require a professional business appraisal when the estate includes a material or hard-to-value private business interest. Form 706 reporting requires supportable values, and private company interests usually lack reliable public market quotations (IRS, n.d.-b, n.d.-c; 26 C.F.R. § 20.2031-1, n.d.).

2. When should an estate attorney require a business appraisal?

Require one when the estate owns a closely held corporation, LLC, partnership, family business, professional practice, holding company, noncontrolling interest, restricted interest, asset-heavy entity, or any business interest with no reliable market price. A professional appraisal is also prudent when beneficiaries may dispute value, when basis reporting may matter, or when the value is material to the return.

3. What standard of value applies for Form 706 business interests?

The estate tax valuation framework uses fair market value. Treasury Regulation section 20.2031-1 describes fair market value by reference to a hypothetical willing buyer and willing seller, neither under compulsion and both reasonably informed about relevant facts (26 C.F.R. § 20.2031-1, n.d.). The appraisal should state and apply the correct standard.

4. What valuation date should the appraisal use?

The appraisal must match the estate’s filing position. Date-of-death value is generally central, while section 2032 provides an alternate valuation framework when requirements are met (26 U.S.C. § 2032, n.d.). Attorneys should coordinate valuation date decisions with the CPA, executor, and appraiser before the report is finalized.

5. Can book value be used instead of a professional valuation?

Book value may be a data point, but it is often not fair market value. It may omit goodwill, reflect depreciated historical cost, ignore market changes, or fail to account for restrictions and earnings power. For private business interests, relying solely on book value can be risky unless the facts strongly support it and advisers document the rationale.

6. Can a buy-sell agreement set the estate tax value?

A buy-sell agreement can be relevant, but it should be reviewed carefully. The attorney and appraiser should examine the agreement’s terms, date, purpose, update history, funding, transfer restrictions, and whether the formula reflects current economics. A stale or formulaic agreement should not be accepted automatically.

7. Which valuation methods are common for private business interests?

Common valuation methods include the income approach, discounted cash flow, capitalized earnings or EBITDA-based analysis, the market approach, and the asset approach. The appropriate method depends on the company’s facts, available data, ownership rights, asset mix, and valuation purpose. A professional report should explain method selection and reconciliation.

8. Are discounts for lack of control or lack of marketability automatic?

No. Discounts and interest-specific adjustments must be supported by the facts. The appraiser should analyze the actual rights, restrictions, control features, transferability, distributions, and market evidence for the subject interest. Generic discount percentages are not a substitute for analysis.

9. Does a professional appraisal prevent an IRS audit or penalties?

No appraisal can guarantee that the IRS will not audit, question, or adjust a value. However, a well-supported appraisal can show a disciplined valuation process and provide evidence for the estate’s reporting position. Penalty provisions exist for valuation misstatements and certain incorrect appraisals, so quality and support matter (26 U.S.C. §§ 6662, 6695A, n.d.).

10. How can valuation affect beneficiary basis?

Section 1014 addresses basis for property acquired from a decedent, and section 6035 and Form 8971 materials may create basis information reporting issues for certain estates (26 U.S.C. §§ 1014, 6035, n.d.; IRS, n.d.-d, n.d.-f). Applicability depends on the estate’s facts. Attorneys should coordinate with the CPA and tax advisers.

11. What documents should attorneys collect for a Form 706 business appraisal?

Collect entity agreements, ownership records, tax returns, financial statements, interim financials, debt schedules, fixed asset lists, leases, buy-sell agreements, prior appraisals, offers, customer/vendor data, management information, real estate or equipment appraisals, and any documents affecting rights or restrictions.

12. How early should the appraiser be engaged?

Engage the appraiser as early as possible after identifying a private business interest. Document collection, management interviews, specialist appraisals, normalization analysis, and draft review can take time. Early engagement also helps counsel coordinate valuation date, alternate valuation, basis, and beneficiary reporting issues.

13. Can the estate’s CPA prepare the business appraisal?

Possibly, depending on qualifications, independence, scope, professional standards, and conflicts. A CPA who prepares tax returns may or may not be the right valuation professional for the assignment. Attorneys should consider credentials, experience, standards compliance, independence, and whether a separate valuation specialist would create a stronger file.

14. What should attorneys look for before relying on a valuation report?

Look for the correct subject interest, valuation date, fair market value standard, purpose, documents reviewed, methods considered, normalization adjustments, ownership-rights analysis, support for discounts or adjustments, reconciliation, assumptions, limiting conditions, and appraiser certification. The conclusion should tie clearly to the Form 706 workpapers.

Conclusion: A Certified Business Appraisal Is a Form 706 Risk-Control Tool

Estate attorneys do not need to become appraisers, but they do need to control valuation risk. A private business interest on Form 706 is not a line item to fill with a guess. It is a hard-to-value asset that may affect estate tax reporting, beneficiary expectations, basis coordination, fiduciary communication, and IRS review. A credentialed, well-documented business appraisal gives the estate a defensible process and a clear explanation of fair market value.

The best practice is simple: identify business interests early, gather documents, engage a qualified valuation professional, coordinate with the CPA and executor, review the report for factual consistency, and retain the appraisal in the estate’s support file. When the estate owns a private company interest, requiring a professional business valuation is usually one of the most practical risk-management steps an estate attorney can take.

For law firms, the operational benefit is just as important as the technical benefit. A repeatable appraisal requirement makes intake cleaner, reduces last-minute document scrambles, and gives associates and paralegals a clear escalation rule. If a private business interest appears in the estate inventory, the file should move immediately into valuation triage: identify the entity, collect governing documents, confirm the decedent’s ownership, determine whether the interest is voting or nonvoting, ask whether restrictions exist, and decide who will speak for the company. That triage process can begin before all tax decisions are final. Waiting until the Form 706 deadline is close often forces the team to accept incomplete documents, rushed management interviews, or inadequate review time.

The appraisal also gives counsel a more disciplined way to discuss value with clients. Executors sometimes expect a low value to reduce estate tax, while beneficiaries may prefer a high value because of perceived basis or fairness considerations. Surviving business owners may have their own incentives. A professional report does not make those tensions disappear, but it changes the conversation from preference to evidence. The attorney can point to the fair market value standard, the valuation date, the documents reviewed, the selected valuation methods, and the appraiser’s reconciliation. That process is easier to defend than a number selected because it was convenient.

Finally, requiring a business appraisal supports the integrity of the estate file. Form 706 workpapers may be revisited months or years later by tax authorities, beneficiaries, successor fiduciaries, or advisers handling a later sale. The people who remember the details may no longer be available. A complete report preserves the reasoning while documents and memories are fresh. For private company interests, that documentation is often the difference between a file that can be explained and a file that must be reconstructed under pressure.
