To appraise a business, you hire a credentialed valuation professional who gathers several years of financial records, chooses a standard of value appropriate to your purpose, applies one or more of three recognized valuation approaches, normalizes earnings to reflect what a new owner would actually take home, and issues a written report. For a small company with straightforward operations, expect fees of roughly $2,000 to $10,000 and a turnaround of three to six weeks once the appraiser has the documents in hand. Complex ownership structures, multiple entities, or unusual assets push both numbers higher. Getting the process right matters because an unsupported figure can trigger IRS penalties, sink a sale, or shortchange a departing owner.
Start With the Standard of Value
Before any numbers are calculated, decide which standard of value governs the engagement. The same business can be worth meaningfully different amounts depending on the standard, and this is where many owners first go wrong by assuming value is value.
Fair market value is what the IRS requires for estate tax, gift tax, and charitable contribution purposes. It represents the price a hypothetical willing buyer and willing seller would agree on, with neither under pressure and both reasonably informed.1eCFR. 26 CFR Section 20.2031-1 Most buy-sell agreements also use this standard.
Fair value is the standard used in shareholder oppression cases, certain state-law dissenting shareholder actions, and financial reporting. The critical practical difference is that fair value often does not permit the discounts for minority interest or lack of marketability that can substantially reduce a fair market value conclusion.
Investment value reflects what the business is worth to a specific buyer, including synergies or strategic advantages a generic purchaser would not enjoy. A business worth $2 million at fair market value might be worth $3 million as investment value to a competitor who can eliminate redundant overhead.
The purpose of the appraisal drives the standard, and the standard drives the number. Confirm this in writing with your appraiser before work begins.
Gather the Financial Records
Clean documentation is the first real work. Most appraisers want three to five years of federal income tax returns: Form 1120 for a C-corporation, Form 1120-S for an S-corporation, or Form 1065 for a partnership. If you have lost copies, request transcripts from the IRS using Form 4506-T.2Internal Revenue Service. About Form 4506-T, Request for Transcript of Tax Return
Tax returns alone are not enough. Add internally prepared balance sheets, profit and loss statements, and cash flow reports covering the same period, ideally broken out monthly so seasonal patterns show. Then compile a register of tangible assets with depreciation schedules: equipment, vehicles, furniture, and any real estate the business owns. Intangibles need their own documentation, including patents, trademarks, customer lists, software licenses, and non-compete agreements currently in force. Outstanding liabilities round out the package: term loans, lines of credit, equipment leases, and unpaid vendor balances. The more organized this material is when you hand it over, the faster and cheaper the engagement.
The Three Valuation Approaches
IRS Revenue Ruling 59-60 is the foundational guidance for valuing closely held businesses, and it makes clear that no single formula produces a reliable answer. In practice, appraisers channel their analysis through three broad approaches and often use more than one, then reconcile the results by weighting each method against how well it fits the company.
Asset-Based Approach
The asset-based approach adds the fair market value of everything the company owns and subtracts all liabilities. It fits asset-heavy businesses like real estate holding companies, equipment rental operations, or manufacturers with valuable plant and machinery. The logic is that a rational buyer would not pay more than the cost of assembling the same assets from scratch. For a profitable consulting firm or software company, though, the balance sheet captures a fraction of the real value. This approach tends to produce the floor rather than the ceiling.
Market Approach
The market approach looks at what similar businesses have actually sold for and derives valuation multiples from those transactions. An appraiser might find that comparable companies in your industry recently sold for four times annual earnings, then apply that multiple to your normalized earnings. Finding truly comparable transactions is the hard part. The appraiser uses standardized industry classification codes to narrow the search, then adjusts for differences in size, geography, growth rate, and deal structure. This method carries significant weight with buyers because it reflects what the market is actually paying.
Income Approach
For profitable operating businesses, the income approach is usually the most detailed and often the most influential. It comes in two main forms.
The capitalization of earnings method takes a single representative year of income and divides it by a capitalization rate. That rate starts with a risk-free rate of return, adds premiums for equity risk, company size, and company-specific factors like customer concentration or thin management, then subtracts the expected long-term growth rate. A higher cap rate means more risk and a lower value.
The discounted cash flow method is more granular. It projects expected cash flows over a defined period, usually five to ten years, and discounts each year back to present value using a rate that reflects the return an investor would demand. A terminal value captures what the business is worth beyond the projection period. This method suits companies with uneven earnings or those in a rapid growth phase where a single-year snapshot would mislead.
A capital-intensive manufacturer might see the asset-based and income approaches weighted most heavily, while a professional services firm leans on the income and market approaches.
Normalize the Earnings
Raw financial statements rarely reflect the economic benefit actually available to a new owner. Normalization strips out expenses that are personal to the current owner, one-time events, and accounting choices that distort profitability. The result is called seller’s discretionary earnings for small businesses or adjusted EBITDA for larger ones.
Common adjustments include adding back above-market owner compensation. If the owner pays herself $300,000 but a replacement manager would cost $150,000, that $150,000 difference gets added back to earnings. Personal expenses run through the business, like vehicles or travel, come back too. So do one-time legal settlements and unusual repair costs from events like a flood or fire. If the business owns the real estate it occupies, rent is adjusted to reflect current market rates rather than whatever internal transfer price the books show. These adjustments can change the picture dramatically. A business that looks marginally profitable on tax returns may show strong discretionary earnings once the owner’s lifestyle is backed out.
How Goodwill Fits In
For many service businesses and professional practices, goodwill is the single largest component of value. It represents earning power that cannot be traced to a specific tangible asset, coming from reputation, customer relationships, brand recognition, a trained workforce, and favorable location.
The distinction between enterprise goodwill and personal goodwill matters enormously, especially in sales and divorces. Enterprise goodwill belongs to the business and transfers with it: a recognizable brand name, established operating systems, a trained staff, a loyal customer base that returns regardless of ownership. Personal goodwill is tied to a specific individual and may not transfer. A skilled surgeon’s reputation, a rainmaker attorney’s client relationships, or a charismatic founder’s industry connections all fall on the personal side.
The allocation has real tax consequences. When a C-corporation is sold, proceeds allocated to the seller’s personal goodwill can be taxed at capital gains rates rather than being double-taxed as corporate income. In divorce, many states exclude personal goodwill from the marital estate because it cannot exist apart from the individual.
Discounts for Partial Ownership Interests
If the interest being appraised is less than 100 percent of the company, two discounts frequently apply, and together they can reduce the value by a third or more compared to a pro rata share of enterprise value.
A discount for lack of control, sometimes called a minority interest discount, reflects that a minority owner cannot force a sale, set dividends, hire or fire management, or drive other key decisions. In private company valuations, this discount commonly runs 15 to 45 percent, though courts increasingly scrutinize anything above 35 percent without strong justification.
A discount for lack of marketability accounts for the difficulty of selling a private company interest compared to publicly traded stock. There is no exchange for private interests, so finding a buyer takes time, effort, and transaction costs. The IRS has published a detailed job aid identifying factors that drive this discount, drawn from the Tax Court’s decision in Mandelbaum v. Commissioner.3Internal Revenue Service. Discount for Lack of Marketability Job Aid for IRS Valuation Professionals Studies analyzing restricted stock transactions have found marketability discounts typically range from about 17 percent at the low end to 36 percent at the high end, with a median around 26 percent.
Fair value, the standard used in many shareholder disputes, often does not allow these discounts. That is one reason choosing the correct standard of value at the outset matters so much.
Choose the Level of Report You Need
Not every situation calls for the same depth of analysis, and understanding the three levels of engagement can save real money.
A full detailed report is the most comprehensive option. The appraiser performs extensive research, applies multiple methods, and produces a document that walks the reader through all the data, reasoning, and conclusions. Use this for IRS filings, litigation, and high-stakes transactions.
A summary report covers the same analytical ground but in condensed form. It suits family law matters, internal planning, or situations where the intended users already know the business and need a supportable opinion of value without sixty pages of narrative.
A calculation engagement is the most limited and least expensive. The appraiser and client agree upfront on which methods to use, and the result is expressed as a “calculated value” rather than a formal opinion. It works for preliminary negotiations or benchmarking. It will not hold up in court or satisfy the IRS for tax reporting, so do not use it where a formal opinion is required.
Hire a Qualified Appraiser
Credentials matter here more than in most professional services. Look for a Certified Valuation Analyst designation from the National Association of Certified Valuators and Analysts, which is accredited by both the National Commission for Certifying Agencies and the ANSI National Accreditation Board.4NACVA. Certified Valuation Analyst (CVA) The Accredited Senior Appraiser designation from the American Society of Appraisers is another widely recognized credential.
For tax-related valuations, the IRS has its own definition of a “qualified appraiser” that requires demonstrated education and experience in valuing the specific type of property at issue.5Internal Revenue Service. Transitional Guidance Regarding Appraisal Requirements for Noncash Charitable Contributions An appraiser qualified to value a restaurant chain may not meet the standard for valuing a biotech patent portfolio.
The engagement begins with an engagement letter setting out scope of work, standard of value, purpose, timeline, and fee. For small businesses with under $10 million in revenue and simple ownership, expect $2,000 to $10,000. Certified valuations intended for IRS filings or litigation tend to run $7,000 to $8,000. Comprehensive engagements for multi-entity structures can exceed $10,000. The appraiser will typically conduct a site visit to inspect physical assets, observe operations, and interview management about things financial statements do not capture, like key customer relationships or pending regulatory changes.
For IRS purposes, the report must follow generally accepted appraisal standards, which the IRS defines as the substance and principles of the Uniform Standards of Professional Appraisal Practice.6eCFR. 26 CFR 1.170A-17 – Qualified Appraisal and Qualified Appraiser The finished report serves as a legal record for tax filings, bank financing, court proceedings, or shareholder transactions.
What Happens If the Number Is Wrong
The IRS imposes an accuracy-related penalty of 20 percent of the underpayment when a value claimed on a return is 150 percent or more of the correct amount. If the claimed value hits 200 percent or more, the IRS treats it as a gross valuation misstatement and doubles the penalty to 40 percent.7Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments These penalties do not apply unless the tax underpayment attributable to the misstatement exceeds $5,000, or $10,000 for C-corporations.
Inflating a valuation for a charitable contribution deduction, or deflating one for estate tax purposes, is not aggressive planning. It is a penalty minefield. A well-documented appraisal from a qualified appraiser is the best defense, because the IRS generally will not impose the penalty if the taxpayer had a reasonable basis for the claimed value and acted in good faith.
If You Disagree With the Result
If you receive a valuation and believe the conclusion is wrong, the standard remedy is an appraisal review. A second credentialed appraiser evaluates the quality of the original work, including whether appropriate methods were used, whether the data supports the conclusions, and whether the report complies with professional standards. The review produces its own written report and can be used to challenge the original valuation in court or in negotiations.
An appraisal review is not the same as a second opinion. A second full appraisal produces an independent value conclusion using the reviewer’s own analysis. A review examines the original report’s methodology and credibility without necessarily performing a new valuation from scratch. In litigation, both tools are common, and the reviewing appraiser may be called as an expert witness. If a buy-sell agreement or court order specifies a dispute resolution mechanism for disagreements over value, follow that process first before commissioning outside work.
