The fair market value (FMV) of closely held business stock refers to the price at which shares of a private company would change hands between a hypothetical willing buyer and a hypothetical willing seller, both having reasonable knowledge of all relevant facts and neither being under compulsion to buy or sell. Because closely held business stock has no public market price, the IRS has established detailed guidance through Revenue Ruling 59-60 and related rulings to govern how FMV must be determined for estate and gift tax purposes. Sofer Advisors, led by David Hern CPA ABV ASA, provides IRS-qualified valuations of closely held business interests for estate tax, gift tax, buy-sell agreements, and ESOP purposes.

Closely held business stock is one of the most valuable and most frequently transferred assets in estate and gift planning. For family-owned businesses, the FMV of the ownership interest determines the estate tax liability, the gift tax basis for transferred shares, the buyout price under a buy-sell agreement, and the ESOP contribution deduction for employee stock ownership plans. An unsupported or inaccurate FMV exposes the estate, the donor, or the plan trustee to IRS penalties, back taxes, and interest. Getting the FMV right requires applying Revenue Ruling 59-60 rigorously, not relying on rules of thumb or internally prepared spreadsheets.

Key Takeaways

  • Revenue Ruling 59-60, issued by the IRS in 1959 and still the foundational authority for closely held stock valuation, identifies eight factors that must be considered in every FMV determination.
  • The three primary valuation approaches for closely held stock are the income approach (capitalized earnings or DCF), the market approach (comparable companies and transactions), and the asset approach (adjusted net asset value).
  • No single formula governs the FMV of closely held stock; the weight given to each approach depends on the nature of the business, its earnings history, and the purpose of the valuation.
  • Discounts for lack of control (DLOC) and lack of marketability (DLOM) often apply when valuing minority interests in closely held companies, significantly reducing the taxable per-share value.
  • A qualified appraisal performed by a qualified appraiser is required by the IRS for estate and gift tax returns claiming business interest deductions or exclusions above certain thresholds.

What Are the Eight Factors in Revenue Ruling 59-60?

Revenue Ruling 59-60, which remains the primary IRS authority for valuing closely held business interests in estate and gift tax contexts, requires appraisers to consider the following eight factors in determining FMV:

  1. Nature of the business and history of the enterprise from its inception. The business’s industry, founding story, operational history, and any cyclicality or volatility in its performance all inform the risk of future cash flows.
  2. The economic outlook in general and the condition and outlook of the specific industry. Macroeconomic conditions and industry-specific trends affect the risk and return expectations of a hypothetical willing buyer. 
  3. The book value of the stock and the financial condition of the business. Book value provides a floor for asset-rich businesses and a context for understanding leverage, liquidity, and working capital adequacy. 
  4. The earning capacity of the company. Historical and normalized earnings are the primary driver of value for most operating businesses, weighted more heavily than book value when earnings are the primary source of return. 
  5. The dividend-paying capacity of the company. Whether the business pays dividends, could pay dividends if it chose to, and the amount of dividends historically paid reflect the income that a hypothetical investor would receive from a minority interest.

How Do the Three Valuation Approaches Apply to Closely Held Stock?

The income approach for closely held stock uses either the capitalized cash flow method or the discounted cash flow (DCF) method. The capitalized cash flow method divides a single normalized earnings figure (typically EBITDA or free cash flow) by a capitalization rate, which is the discount rate minus the long-term growth rate. The DCF method projects multi-year cash flows and discounts them at the WACC, adding a terminal value for cash flows beyond the projection period. The income approach is most appropriate for operating businesses with stable earnings history and predictable cash flows. The market approach for closely held stock applies earnings multiples derived from comparable publicly traded companies (the guideline public company method) or from comparable private company transactions (the guideline transaction method). Guideline public company multiples (EV/EBITDA, EV/Revenue, P/E) reflect minority, marketable values and must be adjusted for size and control differences before applying to a closely held company. Guideline transaction multiples reflect controlling, marketable values.

IRS Valuation Approach Method Used Best Applied To
Income Approach Discounted cash flow, capitalization Operating companies with stable earnings
Market Approach Guideline public companies, transactions Companies with comparable peers
Asset Approach Adjusted net asset value Holding companies, real estate entities
Combined Weighted blend of two or more Most closely held businesses

What Discounts Apply to Closely Held Minority Interests?

When the interest being valued represents less than a 50% controlling position, the appraiser must consider two types of discounts:

The discount for lack of control (DLOC), also called the minority interest discount, reflects the inability of a minority shareholder to direct management, declare dividends, compel a sale, or set compensation. DLOC for closely held businesses typically ranges from 15% to 35%, depending on the specific rights attached to the minority interest, the size of the interest, and the degree of control held by other shareholders. The discount for lack of marketability (DLOM) reflects the illiquidity of private company interests relative to publicly traded stocks. A minority interest in a closely held company cannot be sold quickly; there may be restrictions on transfer, a limited buyer pool, and no ready market.

What Is a Qualified Appraisal and Why Does the IRS Require It?

A qualified appraisal is an appraisal that meets specific IRS requirements set forth in Treas. Reg. Section 1.170A-17 and IRC Section 6662. The IRS requires a qualified appraisal for any estate or gift tax return claiming a deduction or exclusion related to closely held stock above threshold amounts, as well as for charitable contribution deductions of business interests. The appraisal must be conducted by a qualified appraiser, defined as an individual who holds an appraisal designation from a recognized professional appraisal organization or who has met minimum education and experience requirements in valuing the type of property. Recognized designations include ABV (Accredited in Business Valuation, issued by the AICPA) and ASA (Accredited Senior Appraiser, from the American Society of Appraisers).

How Does the Buy-Sell Agreement Affect FMV Determinations?

A buy-sell agreement is a legally binding contract that governs the sale of a business interest when a triggering event occurs, such as the death, disability, or retirement of a shareholder. Buy-sell agreements often specify a valuation mechanism for determining the price at which interests must be bought or sold. The IRS (under Revenue Ruling 59-60 and Treasury regulations) will respect a buy-sell agreement price as FMV for estate tax purposes only if the agreement meets specific tests: the price must be a bona fide business arrangement, it must not be a device to transfer value to family members for less than adequate consideration, and it must be comparable to arm’s-length terms between unrelated parties. Many buy-sell agreements specify that the price is to be determined by an independent appraiser using a specific standard of value.

Frequently Asked Questions

What does “fair market value” mean for closely held business stock?

Fair market value of closely held business stock is the price at which the stock would change hands between a hypothetical willing buyer and a hypothetical willing seller, both having reasonable knowledge of all relevant facts and neither being under compulsion to buy or sell. This definition, from Revenue Ruling 59-60, assumes a hypothetical market participant rather than a specific known buyer, which is why the FMV of closely held stock can differ substantially from the price a strategic buyer with combined benefits might pay.

What is Revenue Ruling 59-60 and why is it important?

Revenue Ruling 59-60 is the IRS’s foundational guidance document for valuing closely held business interests for estate and gift tax purposes. It identifies eight factors that appraisers must consider, describes the three valuation approaches, and explains how weight should be assigned to each factor based on the nature of the business. Issued in 1959, it remains the primary IRS authority on this topic, cited in thousands of Tax Court cases and IRS audit proceedings.

How does the IRS audit a closely held stock valuation?

The IRS audits closely held stock valuations submitted with estate and gift tax returns by assigning the examination to IRS engineers or economists who review the methodology, comparable selection, discount rates, and discount amounts. In complex cases, the IRS retains its own valuation experts. The IRS looks for unsupported discount rates, comparables that are not truly comparable, failure to normalize earnings, and discounts that are outside the typical range without adequate justification.

Do all three valuation approaches need to be used for closely held stock?

No. Revenue Ruling 59-60 requires the appraiser to consider all relevant factors and applicable approaches, but the weight assigned to each approach depends on the specific business. For an operating business with stable earnings, the income approach and market approach typically dominate, and the asset approach is used only as a sanity check or floor. For a holding company whose value is driven by the fair value of its investment portfolio, the asset approach dominates.

What is a minority interest discount in estate planning?

A minority interest discount (DLOC) is a percentage reduction applied to the pro-rata value of a closely held business interest when the interest being valued is less than a controlling position. Because minority shareholders cannot control distributions, management, or the timing of a sale, their interests are worth less per share than a controlling position. In estate planning, family members who receive minority interests as gifts or bequests benefit from DLOC and DLOM, which reduce the FMV reported for tax purposes.

How does an ESOP valuation differ from an estate tax valuation?

An ESOP valuation establishes the fair market value of shares held in or contributed to an Employee Stock Ownership Plan. The Department of Labor and IRS both require that ESOP valuations be performed by an independent qualified appraiser and updated annually. Like estate tax valuations, ESOP valuations use Revenue Ruling 59-60 as the foundational guidance, but they have additional requirements under ERISA and Department of Labor regulations.

Can I use a formula or rule of thumb instead of a qualified appraisal?

No, for IRS purposes. The IRS does not accept formula-based valuations or industry rule-of-thumb multiples as substitutes for a qualified appraisal when an estate or gift tax return is at issue. Formula approaches fail to account for the specific facts and circumstances of the subject company, do not apply the eight Revenue Ruling 59-60 factors, and lack the methodological documentation required for a qualified appraisal.

What is the difference between fair market value and fair value for closely held stock?

Fair market value (FMV) uses the hypothetical willing buyer/willing seller standard from Revenue Ruling 59-60, applicable in estate and gift tax, 409A, and most business appraisal contexts. Fair value (as defined by state law in shareholder dissent and dissolution proceedings) may differ from FMV in that some states require the exclusion of minority and marketability discounts in determining the fair value owed to a dissenting shareholder.

How often does closely held stock need to be valued?

The frequency of closely held stock valuations depends on the purpose. Estate tax valuations are required at the date of death. Gift tax valuations are required at the time of each gift. Buy-sell agreement valuations may be required annually, or upon triggering events as defined by the agreement. ESOP valuations are required annually. 409A valuations are required at least annually and after material events.

What credentials should the appraiser have for a closely held stock valuation?

The IRS requires a qualified appraiser with relevant education and experience. The most widely recognized credentials are ABV (Accredited in Business Valuation) from the AICPA and ASA (Accredited Senior Appraiser) from the American Society of Appraisers. These designations require passing a rigorous examination, completing a minimum number of hours of business valuation work, and adhering to ethical standards. Sofer Advisors’ David Hern holds both ABV and ASA credentials, providing the dual-certified standard that the IRS, Tax Court, and estate attorneys expect for closely held stock valuations.

Executive Summary

The FMV of closely held business stock for IRS purposes is governed by Revenue Ruling 59-60, which requires appraisers to consider eight factors, apply the income, market, and asset approaches as appropriate, and document methodology thoroughly. Minority interests are further reduced by DLOC (15%-35%) and DLOM (20%-35%), applied sequentially. A qualified appraisal from a qualified appraiser is required for estate and gift tax returns claiming business interest valuations above threshold amounts.
