Minority interest discounts—technically termed Discounts for Lack of Control (DLOC)—represent critical adjustments in valuing non-controlling ownership interests in privately held companies. This guide provides authoritative analysis based on current US empirical data, recent court decisions, and IRS enforcement patterns.
Key findings include: (1) typical minority discounts range from 15% to 45%, with courts increasingly skeptical of discounts exceeding 35% without extraordinary justification; (2) the median US control premium of approximately 31% implies minority discounts around 24%; (3) proper documentation and company-specific analysis have become essential for defending discount positions; and (4) technological advances may begin influencing minority shareholder rights, though courts remain focused on current economic realities.
Simply Business Valuation provides valuation services addressing these complexities across estate planning, transaction structuring. The firm's commitment to rigorous analysis ensures defensible valuations that withstand regulatory scrutiny.
The concept of minority interest discounts emerges from a fundamental principle in Business Valuation: a non-controlling ownership interest in a privately held company typically trades at a discount relative to its pro-rata share of the company's total value. This discount reflects the economic reality that minority shareholders lack the ability to control corporate policy, direct management decisions, or compel distributions—limitations that reduce the value of their investment compared to a controlling position.
In the context of US small-to-middle market companies, minority interest discounts play a critical role in various valuation scenarios including estate and gift tax planning, buy-sell agreement implementations, shareholder disputes, and divorce proceedings. The appropriate application of these discounts can significantly impact tax liabilities, transaction values, and wealth transfer strategies, making their proper determination essential for business owners and their advisors.
This guide follows ASA Business Valuation Standards and complies with USPAP 2024-25 Edition requirements for valuation reporting.
IRS Revenue Ruling 59-60 remains the foundational guidance for valuing closely held stock despite being issued over six decades ago. This landmark ruling established the fair market value standard as "the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell, and both having reasonable knowledge of relevant facts." Critically, the ruling explicitly recognized that "control of a corporation, either actual or in effect, representing as it does an added element of value, may justify a higher value for a specific block of stock."¹
The ruling's acknowledgment that "a minority interest in an unlisted corporation's stock is more difficult to sell than a similar block of listed stock" established the conceptual basis for minority discounts that continues to govern valuation practice today. Revenue Ruling 59-60 identified eight specific factors to consider in valuation, including the size of the block of stock to be valued—directly addressing the minority interest issue.
The IRS formalized its acceptance of minority discounts between family members through Revenue Ruling 93-12, which rejected the "family attribution" doctrine. This ruling held that a sole stockholder transferring 20% interests to five children could claim minority discounts for each transfer of non-marketable minority blocks, even though the family collectively maintained control.² This position fundamentally shaped estate planning strategies and established that minority discounts cannot be denied solely based on family relationships.
Current IRS enforcement focuses on challenging excessive discounts rather than the concept itself. Estate tax returns exceeding $10 million face approximately 22% audit coverage according to practitioner surveys and IRS enforcement data.³ The IRS Strategic Operating Plan, bolstered by Inflation Reduction Act funding, targets increasing estate and gift tax audit coverage to 25% by FY 2026.⁵ Gift tax returns experience audit rates near 1%. Key audit triggers include:
The IRS Job Aid for Discount for Lack of Marketability, released publicly in 2011, provides a 107-page window into IRS examination perspectives. This comprehensive guide demonstrates the Service's sophisticated approach to analyzing discounts, emphasizing company-specific factors over generic benchmarks. Similarly, the S Corporation Valuation Job Aid addresses unique considerations for pass-through entities, recognizing that tax attributes can affect both control and marketability characteristics.
The 2016 proposed Section 2704 regulations represented the most significant potential change to minority discount practice in decades. These regulations would have dramatically expanded the restrictions disregarded under Section 2704, effectively eliminating most minority and marketability discounts for family-controlled entities. The proposals introduced a "disregarded restrictions" concept requiring valuation as if no restrictions existed in governing documents or state law.
The withdrawal of these regulations in October 2017 following Executive Order 13789 review maintained the status quo, finding the proposals imposed "undue financial burden" and "undue complexity." As of the Treasury's Fall 2023 Priority Guidance Plan, no revival of the 2016 proposals appears imminent, though practitioners should monitor future administration priorities.⁴ The current Section 2704 framework remains limited to addressing lapsing voting rights and liquidation restrictions more restrictive than state law defaults.
Recent Tax Court decisions reveal an evolution from mechanical discount applications toward case-specific analysis emphasizing economic substance. The Estate of Warne v. Commissioner (T.C. Memo. 2021-17) broke new ground by allowing a 5% lack of control discount for majority interests in real estate LLCs—the first such recognition that even controlling positions may face marketability constraints.⁶
The Holman (T.C. Memo. 2008-83) and Kelly (T.C. Memo. 2012-73) cases demonstrate the Tax Court's middle-ground approach, accepting minority discounts in the 12-15% range for family limited partnerships while rejecting more aggressive positions.⁷ Estate of Newberry (T.C. Memo. 2024-189) reinforced this trend, rejecting a 40% combined discount as excessive for an operating business with consistent profitability.⁸
Delaware's approach to minority discounts reflects crucial distinctions between valuation contexts. In statutory appraisal proceedings under 8 Del. C. § 262, Delaware courts apply a "fair value" standard that excludes minority and marketability discounts. However, in contractual valuation contexts using "fair market value" language, Delaware courts may accept such discounts.⁷
Blaustein v. Lord Baltimore Capital Corp. (2013 WL 1810956) exemplifies Delaware's rejection of implied fiduciary duties to provide minority buyout rights in the contractual context, holding that courts cannot rewrite shareholder agreements to create protections not explicitly negotiated.⁸ This strict contractual approach creates planning opportunities through careful agreement drafting.
State courts exhibit significant variation in minority discount treatment. New York's Congel v. Malfitano (31 N.Y.3d 272 (2018)) applied a 66% minority discount to a wrongfully dissolving partner, demonstrating courts' willingness to use discounts punitively.⁹ California's Cheng v. Coastal L.B. LLC (44 Cal. App. 5th 908 (2020)) upheld 27% discounts for LLC interests under the Revised Uniform Limited Liability Act, distinguishing between "fair market value" (allowing discounts) and "fair value" (prohibiting them).¹⁰
The FactSet/BVR Control Premium Study, encompassing 17,400 screened transactions through March 31, 2025, provides comprehensive empirical support for minority discount analysis.¹³ The Q2 2025 median US control premium of 30.8% implies minority discounts of 23.6% using the formula: Minority Discount = 1 - [1/(1 + Control Premium)].
Additional support from recent studies:
Industry variation proves substantial, with the following ranges based on FactSet/BVR data:

| Industry Sector | Typical Discount Range | Control Premium Range | Key Factors |
|---|---|---|---|
| Manufacturing | 25-40% | 33-67% | Asset intensity, cyclicality |
| Professional Services | 20-35% | 25-54% | Human capital dependency |
| Retail | 25-45% | 33-82% | Inventory risks, competition |
| Real Estate | 15-30% | 18-43% | Asset transparency |

The Stout Restricted Stock Study 2023 Edition analyzes 775+ rigorously screened transactions from 1980 through December 2022, providing widely-used marketability benchmarks.¹⁶ The study's median discount of 25.8% reflects transactions across multiple industries, with quartile ranges from 16.7% (25th percentile) to 35.9% (75th percentile).
Traditional restricted stock studies face criticism for limited current applicability. As Mercer (2023) notes, original studies covered only 764 transactions from 1966-1988, making their relevance questionable for contemporary valuations.¹⁷
The sequential application of minority and marketability discounts can produce combined reductions that courts increasingly view as excessive. Consider this numerical example:
Table: Sequential vs. Integrated Discount Application
| Approach | Calculation | Result | Total Discount |
|---|---|---|---|
| Sequential Application | |||
| Starting value | $1,000,000 | $1,000,000 | - |
| Apply 30% DLOC | × (1 - 0.30) | $700,000 | 30% |
| Apply 25% DLOM | × (1 - 0.25) | $525,000 | 47.5% |
| Integrated Approach | |||
| Starting value | $1,000,000 | $1,000,000 | - |
| Apply 35% combined | × (1 - 0.35) | $650,000 | 35% |
The 12.5 percentage point difference ($125,000 on a $1 million interest) illustrates why courts scrutinize mechanical sequential applications.
Reverse-Engineering Integrated Discounts:
An integrated 35% discount can be decomposed into implicit components:
This transparency helps courts understand the economic rationale behind integrated approaches.
Leading valuation theorist Chris Mercer champions the concept that properly constructed income approaches inherently capture minority interest characteristics. This theory posits that public market pricing already reflects financial control value rather than minority value, making marketable minority and financial control values essentially equivalent.¹⁶

Control discount: $7.5M × 19% = $1.425M
Interim value: $7.5M - $1.425M = $6.075M
Marketability disc: $6.075M × 25% = $1.519M
Final value: $6.075M - $1.519M = $4.556M
Total discount: 39.3% from pro-rata

Based on analysis of empirical studies and court decisions from 2010-2025, minority interest discounts for US small-to-middle market private companies most commonly fall within the inter-quartile range of 15% to 45%. The median US control premium of 30.8% (FactSet/BVR Q2 2025) implies minority discounts of 23.6%. Courts show increasing skepticism toward discounts exceeding 35% without extraordinary justification.
Minority interest discounts (DLOC) reflect a lack of control over corporate decisions, while marketability discounts (DLOM) address the difficulty of converting ownership to cash. Though conceptually distinct, these discounts share overlapping factors. Courts increasingly scrutinize combined discounts exceeding 50% as potentially excessive (see numerical example in Section 5).
Yes, the IRS actively examines excessive or inadequately supported minority discounts. Per IRS Data Book FY 2024, estates exceeding $10 million face approximately 11% audit coverage. The Service focuses on economic substance, requiring legitimate business purposes and proper documentation per Revenue Ruling 59-60 standards.
The landscape of minority interest discounts continues evolving through judicial sophistication and theoretical advancement. Success requires nuanced understanding of company-specific factors, regulatory requirements, and economic substance supported by current empirical data. The median US control premium of 30.8% and implied minority discount of 23.6% provide benchmarks that must be adjusted for specific circumstances.
As courts increasingly scrutinize mechanical applications and the IRS targets 25% audit coverage for high-value estates by 2026, proper documentation and economic substance become paramount. Practitioners must balance established precedent with emerging theory while maintaining defensible positions grounded in empirical evidence.
