A business appraisal is a formal analysis, performed by a credentialed professional, that determines the economic value of an ownership interest in a privately held company. Because private companies have no stock ticker to set a daily price, an appraisal is the only defensible way to arrive at a number that will hold up with the IRS, in court, or across the table from a buyer. Reports for small and mid-sized companies typically run from $5,000 to $20,000, and the figure they produce drives real dollars: the tax owed on a gifted stake, the price in a sale, the buyout owed to a departing partner.
When You Actually Need One
Valuations come up more often than most owners expect, and the trigger is rarely optional. Four situations account for most engagements.
Transactions are the obvious one. Selling a company, buying a competitor, admitting a new partner, or structuring a merger all require an independent opinion of value. Deal financing frequently hinges on a credible appraisal, and without one neither side has a reliable basis for negotiation.
Tax compliance is the second. Estate tax returns (Form 706) and gift tax returns (Form 709) frequently require a valuation when the estate or gift includes privately held stock. Charitable contributions of closely held stock valued above $5,000 also require a qualified appraisal attached to the return.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts Missing in either direction creates real exposure to IRS penalties.
Litigation is the third. Shareholder disputes, partner buyouts, and divorce proceedings all demand a formal determination of value, and the appraiser’s methodology will face cross-examination. A sloppy report gets torn apart.
The fourth is financial reporting. Companies following Generally Accepted Accounting Principles may need appraisals for purchase price allocation after an acquisition or for annual goodwill impairment testing. These are accounting requirements, not optional exercises.
The Standard of Value Comes First
Before any calculations begin, the appraiser has to identify which standard of value applies. The standard defines the hypothetical conditions of the transaction being modeled, and the wrong choice produces a number that may be useless for its intended purpose.
Fair Market Value
Fair market value is the default for tax and most transactional work. The IRS defines it as the price property would sell for on the open market, agreed between a willing buyer and willing seller, with neither required to act and both having reasonable knowledge of the facts.2Internal Revenue Service. Publication 561 – Determining the Value of Donated Property The key word is hypothetical. Fair market value doesn’t ask what a specific buyer would pay; it asks what the market in general would pay.
Fair Value
Fair value is the same term used two different ways. Under ASC 820, the accounting standard, it is the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date.3U.S. Securities and Exchange Commission. Note 10 Fair Value Measurements In state-level litigation, such as shareholder oppression cases, fair value is defined by state corporate statute and frequently excludes discounts for lack of marketability or minority status. That exclusion can produce a substantially higher number than fair market value for the same interest.
Investment Value
Investment value is what the business is worth to one particular buyer, incorporating synergies, cost savings, or strategic advantages unique to that buyer. Because it captures value that only exists for that purchaser, investment value is almost always higher than fair market value. It shows up most often in acquisition planning, where the buyer needs to understand the ceiling they can pay without destroying value.
The Three Approaches Appraisers Use
Credible appraisals apply more than one approach and then reconcile the results, weighting whichever method best fits the company’s industry and financial profile. There are three.
Income Approach
The income approach values a business based on what its future cash flows are worth today. A buyer is really purchasing a stream of future economic benefits, and those benefits get translated into a present-day figure that accounts for risk and the time value of money.
The most common technique is the discounted cash flow (DCF) method. The appraiser projects cash flows over a defined period, typically five years, then discounts each year back to the present using a discount rate that reflects the risk of those cash flows materializing. Company size, industry volatility, and capital structure all feed into the rate. A riskier business gets a higher discount rate, which pushes the value down. Beyond the projection period, the appraiser adds a terminal value representing the company’s worth from that point forward under an assumed stable growth rate. That terminal figure often accounts for the majority of the total result, so the growth assumption deserves scrutiny.
For mature companies with steady, predictable earnings, appraisers sometimes use the capitalization of earnings method instead. This divides a single measure of normalized income by a capitalization rate (essentially the discount rate minus the expected long-term growth rate). Simpler than a full DCF, but it only works when earnings aren’t expected to fluctuate significantly.
Market Approach
The market approach values a business by comparing it to similar companies that have recently been sold or are publicly traded. The underlying principle is substitution: an informed buyer won’t pay more for a company than the price of a comparable alternative.
Under the guideline public company method, the appraiser identifies publicly traded peers and extracts valuation multiples from their stock prices, such as enterprise value to EBITDA. Those multiples get applied to the subject company’s own metrics, with adjustments for differences in size, growth, and risk. A small private manufacturer trades at lower multiples than a large publicly traded competitor, so raw comparisons without adjustment produce inflated numbers.
The guideline transaction method looks instead at prices paid in actual acquisitions of private companies. Those multiples are often more directly relevant because they reflect what buyers actually paid for control of a whole business. The catch is finding enough comparable transactions with reliable, publicly available financial data.
Asset Approach
The asset approach adds up the fair market value of everything the company owns and subtracts its liabilities. The appraiser starts with the balance sheet and adjusts each line item from book value to current market value: real estate at current prices, equipment at replacement or liquidation value, intangible assets like patents or customer lists at their estimated economic worth.
This approach fits holding companies, real estate-heavy businesses, and companies facing liquidation. For operating businesses whose value comes from earnings rather than physical assets, the asset approach usually produces the lowest figure and serves more as a floor than a primary indicator. Appraisers still calculate it as a reasonableness check.
Why the Reported Financials Aren’t the Starting Point
Before any of the models get numbers, the appraiser adjusts the company’s reported financials to reflect its true economic performance. These normalization adjustments strip out items that would distort the picture for a hypothetical buyer.
Owner-related items are the most common target. Many private owners pay themselves above- or below-market compensation, run personal expenses through the company, or employ family members at inflated salaries. The appraiser restates compensation to market rates so earnings reflect what a new owner would actually realize.
Non-recurring items also come out. A one-time lawsuit settlement, a gain from selling surplus real estate, or a casualty loss doesn’t represent ongoing earning power. If the company’s accounting choices (such as accelerated depreciation) differ from industry norms, the appraiser may adjust to make the financials comparable to peers. Related-party transactions, like renting space from the owner’s separate real estate entity at below-market rates, are restated to arm’s-length terms.
A lot of the real analytical work happens here, and it is one of the easiest places for disputes to arise. An appraiser who doesn’t dig into the details will produce a number that reflects the owner’s personal financial decisions rather than the company’s actual value.
Discounts and Premiums for the Specific Interest
The raw value produced by the three approaches represents the entire enterprise or a controlling interest. When the appraisal is for something else, the value has to be adjusted through discounts or premiums that reflect the specific ownership interest being valued.
Discount for Lack of Control
A minority owner can’t set strategy, declare dividends, hire or fire management, or force a sale. Those limitations reduce what a buyer would pay. The discount typically runs 15% to 35% of the pro rata enterprise value, depending on the size of the stake and whatever governance rights the operating agreement or bylaws provide. A 20% owner with a board seat and veto rights over major decisions takes a smaller discount than a 5% owner with no protective provisions.
Discount for Lack of Marketability
Private company stock can’t be sold on an exchange with a click. Finding a buyer takes time, involves transaction costs, and carries uncertainty about the price. Studies of restricted stock, where publicly traded shares are temporarily barred from resale, consistently show discounts of 20% to 35%. Pre-IPO studies suggest even larger markdowns. Both discounts can stack, so a minority interest in a private company might carry a combined discount of 40% or more off the full enterprise value.
Control Premium
When the interest being appraised carries the power to direct the company, a control premium may apply. Control brings the ability to set dividends, restructure operations, sell assets, and determine strategy. The premium is derived from observable premiums paid in actual mergers and acquisitions above the pre-deal trading price of the target’s stock.
The IRS scrutinizes all of these adjustments closely. Discounts that fall outside established study ranges or that lack company-specific justification invite audit challenges.
IRS Rules When the Appraisal Supports a Tax Filing
When a valuation supports a tax return, both the taxpayer and the appraiser are held to specific standards. Missing them can mean losing a deduction entirely or facing significant penalties.
Qualified Appraisal Requirements
For charitable contributions of property valued above $5,000, the tax code requires a qualified appraisal by a qualified appraiser. A qualified appraiser must hold a designation from a recognized professional organization or meet minimum education and experience requirements, regularly perform appraisals for compensation, and demonstrate verifiable experience valuing the type of property at issue.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts Anyone barred from practicing before the IRS within the prior three years is disqualified.
The appraisal itself must comply with generally accepted appraisal standards, which IRS regulations define as the substance and principles of the Uniform Standards of Professional Appraisal Practice (USPAP).4eCFR. 26 CFR 1.170A-17 – Qualified Appraisal and Qualified Appraiser The report must include a sufficiently detailed property description, the valuation effective date, the concluded fair market value, and the terms of any agreement about the property’s future disposition. For contributions exceeding $500,000, the full appraisal must be attached to the return.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
Valuation Misstatement Penalties
When a valuation claimed on a return misses by a wide enough margin, the IRS imposes accuracy-related penalties on the tax underpayment. There are two tiers. If the claimed value of property is 150% or more of the correct value, the penalty is 20% of the underpayment attributable to that misstatement. If the claimed value hits 200% or more of the correct value, the penalty doubles to 40% of the underpayment.5Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
These apply to overvaluations that inflate a charitable deduction and to undervaluations that understate estate or gift values. A qualified appraisal that follows USPAP and uses reasonable assumptions is the taxpayer’s primary defense.
Timeline, Documents, and Cost
A typical engagement takes roughly two to four weeks from the date the appraiser receives all requested documents. The word “all” carries weight. Delays almost always trace back to the owner taking weeks to assemble records, not the appraiser taking weeks to analyze them.
Expect requests in four categories:
- Organizational documents: articles of incorporation, bylaws, operating agreements, buy-sell agreements, and records of any prior ownership transfers or valuations.
- Historical financials: typically five years of financial statements and tax returns, plus interim statements through the valuation date, depreciation schedules, capital expenditure records, and details on non-operating assets like excess cash or loans to owners.
- Compensation data: salary, bonus, and benefit information for owners and key employees, plus documentation of related-party transactions such as family members on payroll or below-market rent from an owner-controlled entity.
- Projections: three-to-five-year forecasts, including projected capital spending and working capital needs. If the company doesn’t prepare formal projections, the appraiser builds them from management interviews and industry data.
After document review, the appraiser typically conducts a management interview covering competitive position, customer concentration, key-person dependencies, and growth outlook, then performs the analysis, drafts the report, and presents findings.
Fees generally run from $5,000 to $20,000 for a small to mid-sized company. Complex engagements involving multiple entities, international operations, or unusual asset structures push costs considerably higher. Drivers of higher fees include the number of valuation approaches required, the need for outside specialists such as real estate appraisers or intellectual property experts, and the complexity of the capital structure. Most appraisers charge either a flat fee or an hourly rate set before the engagement begins.
How to Pick a Qualified Appraiser
Not all credentials carry the same weight, and for tax work the IRS specifically requires a qualified appraiser. Three designations dominate the field.
The Accredited Senior Appraiser (ASA) is granted by the American Society of Appraisers and requires passing a comprehensive exam plus a minimum of five years of full-time valuation experience.6American Society of Appraisers. Information About ASA, NACVA, AICPA, CBV Institute, and RICS
The Certified Valuation Analyst (CVA), issued by the National Association of Certified Valuators and Analysts, is the only business valuation credential accredited by both the National Commission for Certifying Agencies and the ANSI National Accreditation Board.7National Association of Certified Valuators and Analysts. Holding an ASA Is a Fast Track to the CVA Credential
The Accredited in Business Valuation (ABV) is granted by the American Institute of CPAs exclusively to licensed CPAs who demonstrate specialized valuation expertise.8American Institute of CPAs. ABV Credential Handbook
Beyond the credential, look for direct experience in your industry and with your specific type of engagement. An appraiser who routinely values manufacturing companies for estate tax purposes isn’t necessarily the right choice for a technology startup being valued in a divorce. Ask how many similar engagements they’ve completed and whether their valuations have been challenged in court or by the IRS.
All credentialed appraisers are expected to follow USPAP, which Congress recognized in 1989 as the national standard governing professional appraisals.9American Society of Appraisers. American Society of Appraisers Standards USPAP compliance is what gives the report its defensibility in tax filings, courtroom testimony, and deal negotiations. That defensibility is what you are actually buying.
