A third-party valuation is an independent expert’s opinion of what a business, ownership interest, or asset is worth on a specific date. Companies and individuals commission one when a tax authority, a court, an auditor, or a counterparty needs assurance that the number is honest and defensible. The valuer has no financial stake in the outcome, which is what gives the conclusion credibility with the people who will scrutinize it. Expect a professional engagement to run seven to fourteen weeks and cost anywhere from $2,000 for a small business to well above $10,000 for complex structures, with penalties on the back end that can reach 40% of a tax underpayment if the number turns out to be badly wrong.
When You Actually Need One
Most people don’t commission a valuation because they’re curious. They do it because a specific rule, filing, deal, or dispute requires one. The common thread across every trigger is that someone other than the owner needs to believe the number.
Tax Filings
The IRS requires a third-party valuation whenever it needs to confirm the fair market value of property that doesn’t trade on a public exchange. Two situations drive most of this work.
The first is stock option pricing at private companies. Section 409A requires that the exercise price of a stock option equal or exceed the stock’s fair market value on the grant date. A discounted option triggers immediate income inclusion on vesting, a 20% additional tax on top of ordinary income tax, and interest on the underpayment.1Office of the Law Revision Counsel. 26 USC 409A – Inclusion in Gross Income of Deferred Compensation Under Nonqualified Deferred Compensation Plans Treasury Regulations create a safe harbor: an independent appraisal obtained within twelve months before the grant date is presumed reasonable unless the IRS shows the method or its application was grossly unreasonable.2eCFR. 26 CFR 1.409A-1 – Definitions and Covered Plans That is why virtually every venture-backed startup commissions what the industry calls a 409A valuation before each option grant.
The second is estate and gift tax planning. When someone transfers a closely held business interest to heirs or a trust, the return needs a defensible fair market value. The foundational guidance for valuing stock in a closely held company is IRS Revenue Ruling 59-60, which lays out factors like earning capacity, dividend history, book value, and the economic outlook for the industry. A report that follows these principles is far harder for the IRS to challenge years later.
Financial Reporting
Public and many private companies need valuations to comply with GAAP. After a merger or acquisition, FASB’s Accounting Standards Codification Topic 805 requires the buyer to allocate the purchase price across the assets acquired and liabilities assumed, measured at fair value. This purchase price allocation determines how much of the deal price shows up as goodwill versus identifiable assets like customer relationships, technology, or brand names.
Goodwill then has to be tested. Topic 350 requires at least an annual impairment test comparing the fair value of each reporting unit to its carrying amount, with a write-down if fair value has dropped below book value.3FASB. Goodwill Impairment Testing Auditors expect this analysis to come from an independent valuation professional.
Transactions and Board Decisions
When a board approves a sale, merger, or major asset disposition, directors owe a duty of care to shareholders. A fairness opinion is a specific type of third-party valuation that assesses whether the financial terms are fair to non-controlling shareholders. It doesn’t guarantee the board got the best possible deal, but it documents that directors took reasonable steps to evaluate the price. Without one, directors facing a shareholder lawsuit have a much harder time defending the decision.
Litigation and Disputes
Courts and arbitration panels rely on valuations to attach a dollar figure to contested interests. Shareholder oppression cases, where a minority owner seeks a fair buyout, almost always involve competing valuation experts. Divorce proceedings where one or both spouses own a business are the other common setting. The expert may need to testify, so the report has to withstand cross-examination.
Who Is Qualified to Perform One
No federal license exists for business valuation professionals. Credibility comes from recognized credentials, each requiring substantial education, exams, and continuing education. For tax work there is also a specific regulatory definition you should check against.
The Main Credentials
Three designations dominate the field:
- The Accredited Senior Appraiser (ASA), granted by the American Society of Appraisers, requires five years of full-time appraisal experience at 2,000 hours per year, a four-course curriculum in business valuation principles, and a comprehensive exam.4American Society of Appraisers.

- The Accredited in Business Valuation (ABV) is available only to licensed CPAs who are AICPA members in good standing. The CPA background makes ABV holders well-suited for tax-driven valuations.5AICPA & CIMA. Gain Credibility in Valuation
- The Certified Valuation Analyst (CVA), conferred by the National Association of Certified Valuators and Analysts, is the only valuation credential accredited by both the National Commission for Certifying Agencies and the ANSI National Accreditation Board.6National Association of Certified Valuators and Analysts (NACVA).

The IRS “Qualified Appraiser” Rule
For tax filings, the regulations separately define a “qualified appraiser” as someone with verifiable education and experience in valuing the specific type of property, who has either completed professional-level coursework plus two years of experience or earned a recognized appraiser designation.7eCFR. 26 CFR 1.170A-17 – Qualified Appraisal and Qualified Appraiser For estate, gift, or charitable contribution purposes, hiring someone who meets this regulatory definition matters because the IRS can disregard a report prepared by someone who doesn’t.
Governing Standards
Two frameworks govern how valuations are performed. The Uniform Standards of Professional Appraisal Practice (USPAP) sets ethical and performance rules across appraisal disciplines and has become the broadly accepted ethical standard for business valuation.8Appraisal Subcommittee. USPAP Compliance and Appraisal Independence For CPAs performing valuation work, the AICPA’s Statement on Standards for Valuation Services (VS Section 100) provides binding guidance on how to perform and report engagements.9AICPA & CIMA. Statement on Standards for Valuation Services (VS Section 100)
How the Valuer Arrives at a Number
A qualified valuer considers three fundamental approaches. Usually one or two end up driving the final answer, and the report explains which were used, which were rejected, and how the different indications were reconciled into a single conclusion.
The Income Approach
The income approach treats a business as a stream of future cash flows and asks what that stream is worth today. It is the workhorse for operating companies with predictable earnings. In the discounted cash flow method, the valuer projects cash flows year by year over a forecast period (often five to ten years), adds a terminal value for everything beyond that horizon, and discounts the whole stream to present value at a rate that reflects the risk of the projections. Higher risk means a higher discount rate and a lower present value. The capitalization of earnings method is a shortcut for mature businesses with stable cash flows: a single representative earnings figure is divided by a capitalization rate (the discount rate minus the expected long-term growth rate).
The math is simpler than it looks. The judgment lives in the inputs: growth rates, margins, capital spending, and the discount rate itself.
The Market Approach
The market approach looks at what similar businesses have actually sold for or are currently trading at. The guideline public company method derives valuation multiples (like enterprise value-to-EBITDA or price-to-earnings) from publicly traded peers and applies them to the subject company’s financials. The guideline transaction method does the same thing using data from actual sales of entire private companies; those multiples tend to run higher because they include the premium a buyer pays for outright control.
The hard part is finding genuinely comparable companies. Pick poor comparables (wrong industry, wrong growth stage, wrong risk profile) and the number is misleading. This is where experienced judgment separates good valuations from bad ones.
The Asset Approach
The asset approach adds up the fair market value of everything the company owns and subtracts everything it owes. It fits holding companies, real estate-heavy businesses, and companies facing liquidation. For an operating company it typically sets a floor: the minimum someone would pay before considering the company’s earning power. The adjusted net asset method restates each balance sheet item from book value to current fair market value, which means real estate gets appraised, equipment gets repriced, and intangibles that never appeared on the books (customer lists, proprietary technology, trade names) get identified and valued separately.
Discounts, Premiums, and the Standard of Value
The raw indication from any approach is rarely the final answer. Two adjustments appear in nearly every valuation of a privately held company.
A discount for lack of marketability reflects the fact that selling a private interest is harder, slower, and less certain than selling publicly traded shares. Empirical studies suggest these discounts commonly range from 20% to 40%, depending on factors like company size, transferability restrictions, dividend history, and the likelihood of a future liquidity event. A discount for lack of control applies when valuing a minority interest that can’t set strategy, force distributions, or sell the business. A 30% interest is worth less per share than a 100% interest because the minority holder can’t control how the money gets spent. A control premium may run the other direction when the interest carries majority voting power.
The standard of value defines the hypothetical transaction being modeled, and it has to be set at the start of the engagement because it changes the final number. Two standards dominate practice:
- Fair market value is the price at which property would change hands between a willing buyer and a willing seller, neither under pressure, both reasonably informed. This is the standard for nearly all federal tax purposes. Discounts for lack of marketability and lack of control typically apply.
- Fair value is used for financial reporting under GAAP and in certain litigation contexts such as shareholder buyout disputes in many states. Under GAAP, fair value is the exit price in an orderly transaction between market participants. In litigation, fair value often protects minority shareholders by excluding discounts for lack of marketability or lack of control, on the view that a squeezed-out minority holder is not a willing seller.
Separately, the premise of value specifies whether the business is assumed to keep operating indefinitely (going concern) or is shutting down and selling off assets (liquidation). Going-concern value is almost always higher because it captures the earning power of the assembled enterprise.
Valuation Engagement vs. Calculation Engagement
Not every situation calls for a full valuation. Under VS Section 100, there are two engagement types. In a valuation engagement, the analyst applies whatever approaches and methods they deem appropriate and issues a fully supported conclusion of value. In a calculation engagement, the analyst and client agree in advance on which specific approaches and methods will be used, and the result is a “calculated value” rather than a formal conclusion.10AICPA & CIMA. VS Section 100 – Calculation Engagement and Report FAQs
A calculation engagement costs less and takes less time, but the report explicitly states that the analyst did not perform a full valuation and that the calculated value might differ from a conclusion of value. Calculation engagements work for internal planning, preliminary deal negotiations, or early-stage dispute resolution. They generally will not satisfy IRS filing requirements, court proceedings, or any situation where the number has to withstand adversarial scrutiny.
What to Prepare
The single biggest factor in how long a valuation takes and what it costs is how prepared the client is. Document delays are the most common reason engagements run past deadline.
Scope and Date
Pin down exactly what is being valued (the whole company, a 25% membership interest, a specific asset class) and the valuation date. The valuation date is the specific point in time to which the conclusion applies, and the valuer will use only information and economic conditions known or reasonably knowable as of that date. A major contract signed two weeks after the valuation date generally doesn’t factor in.
Documentation
Expect the valuer to request a substantial package covering three to five years of history:
- Income statements, balance sheets, and cash flow statements, preferably audited or reviewed by a CPA.
- Complete federal and state tax returns for the business.
- Organizational documents, including articles, operating agreements, shareholder agreements, and any buy-sell provisions, which tell the valuer what rights and restrictions attach to each ownership class.
- A list of non-operating assets not used in the core business (excess real estate, investment portfolios, personal vehicles on the books).
- Material contracts: key customer and supplier agreements, leases, debt agreements, and pending or threatened litigation.
- Management’s financial projections for revenue, expenses, and capital spending. The quality of these forecasts directly affects any income-approach analysis.
Management Interviews
Financial statements tell only part of the story. The valuer will interview key personnel to understand competitive dynamics, customer concentration, management depth, and the assumptions behind the projections. A team that can clearly articulate the company’s strategy and risks produces a stronger report. Vague or inconsistent answers create problems that surface later.
How the Engagement Runs
Once the documents are in and the interviews are done, the analytical work follows a defined sequence.
The valuer first normalizes the historical financials to reflect what the business would look like under typical market conditions with arm’s-length transactions. Owner compensation gets adjusted to market rates if the owner pays themselves well above or below what a replacement executive would cost. Related-party transactions (rent to a building the owner also owns, supplies from a family member’s company) get restated to what an unrelated party would charge. Non-recurring items like lawsuit settlements, restructuring costs, and one-time insurance recoveries come out. Personal expenses run through the business get added back to earnings. These adjustments feed every subsequent calculation, so an error here flows through to the final number.
With normalized financials, the valuer applies the selected approaches, produces preliminary value indications, and reconciles them based on how reliable the underlying data is and how well each approach fits the subject company. Any applicable discounts or premiums are then applied to reach the final conclusion.
The client gets a draft report for a narrow review limited to factual accuracy. You verify things like the company’s history, customer descriptions, and how the business model is characterized. This is not a negotiation over the value. The conclusion has to remain the valuer’s independent determination, and pressuring the valuer to change the number undermines the entire purpose of the engagement. The final report typically includes an executive summary, the defined scope and standard of value, an industry and economic analysis, a detailed explanation of each methodology, the key inputs and assumptions, and the reconciliation into a single conclusion. In litigation or regulatory settings, this is the document that goes in front of a judge, an IRS examiner, or an audit committee.
Cost and Timeline
For small businesses with less than $10 million in annual revenue, a professional valuation typically runs between $2,000 and $10,000. A less formal estimate for internal planning might come in at $1,500 to $4,000. A certified valuation suitable for IRS filings, litigation, or a divorce proceeding typically costs $7,000 to $8,000. Multi-entity structures, complex capital arrangements, or international operations push engagements above $10,000 and often considerably higher. When the valuer provides expert testimony, hourly rates for court preparation and testimony commonly run $350 to $500 per hour on top of the base engagement fee.
A typical engagement takes seven to fourteen weeks. The timeline depends heavily on how quickly complete documentation arrives. Complex businesses and litigation valuations tend toward the longer end, the latter because the report has to anticipate cross-examination and opposing experts.
Penalties for Getting It Wrong
The IRS treats inaccurate valuations as serious, and the penalties reach both the taxpayer and, in some cases, the appraiser.
Taxpayer Penalties
If you claim a property value on a tax return that turns out to be 150% or more of the correct value, the IRS treats it as a substantial valuation misstatement and imposes a 20% accuracy-related penalty on the resulting tax underpayment. At 200% or more, the misstatement becomes “gross” and the penalty doubles to 40%.11Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments These penalties apply to estate and gift tax valuations, charitable contribution deductions, and other filings where property value matters.
Appraiser Penalties
Appraisers face their own consequences. If an appraiser prepares a valuation they know or should know will be used on a tax return, and that valuation results in a substantial or gross misstatement, the appraiser pays a penalty equal to the greater of 10% of the tax underpayment caused by the misstatement or $1,000, capped at 125% of the gross income the appraiser received for the appraisal.12Office of the Law Revision Counsel. 26 USC 6695A – Substantial and Gross Valuation Misstatements Attributable to Incorrect Appraisals The appraiser can avoid the penalty by showing the appraised value was more likely than not correct, but that’s a defense they have to prove.
These provisions are the strongest practical reason to hire a well-credentialed, independent valuer rather than cutting corners. A defensible report from a qualified professional is the best protection against both penalties and the cost of relitigating the value years later.
