Fair Market Value
The price at which a business would change hands between a willing buyer and a willing seller, both having reasonable knowledge of the relevant facts and neither being under compulsion to act -- the standard of value used for tax and legal purposes.
What is Fair Market Value?
Fair Market Value (FMV) is a legal and financial standard that defines the price a business would command in a hypothetical open-market transaction between informed, willing parties acting without pressure. It is the most commonly referenced standard of value in tax law, estate planning, litigation, and regulatory compliance.
The IRS defines fair market value as:
"The price at which the 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."
Fair Market Value vs. Strategic Value
FMV and strategic value are fundamentally different concepts, and confusing them is a common and costly mistake.
Fair market value assumes a hypothetical buyer -- a generic, rational investor. It does not account for synergies, competitive advantages, or strategic motivations specific to a particular acquirer.
Strategic value reflects what a specific buyer is willing to pay based on the unique benefits they expect to capture. A competitor may pay a premium to eliminate a rival. A company seeking vertical integration may pay above FMV to secure a critical supplier. A private equity firm may pay more because the acquisition completes a platform strategy.
In most arm's-length M&A transactions, the actual sale price exceeds fair market value because real buyers bring strategic motivations that the FMV framework intentionally excludes.
When Fair Market Value Applies
FMV is the required standard of value in several important contexts:
- Estate and gift tax -- Business interests transferred at death or by gift must be valued at FMV for tax purposes.
- ESOP transactions -- Employee Stock Ownership Plans must purchase shares at FMV as determined by an independent appraiser.
- Charitable contributions -- Donated business interests require FMV appraisals.
- Shareholder disputes -- Courts often use FMV to resolve disagreements over the value of minority interests.
- Divorce proceedings -- Business interests are typically valued at FMV for equitable distribution.
How FMV is Determined
A qualified business appraiser determines FMV using the same three approaches applied in any valuation -- income, market, and asset-based -- but applies them under the specific assumptions required by the FMV standard. Discounts for lack of marketability and lack of control are commonly applied to minority interests.
Advice for Sellers
Understand the difference between fair market value and what a strategic buyer might actually pay. If you need a formal FMV appraisal for tax or legal purposes, engage a credentialed appraiser (ASA, ABV, or CVA designation). For sale purposes, focus on strategic value -- the premium a motivated buyer will pay above the FMV baseline.
