Business Valuation Expert: When to Hire One, What They Cost, and What You Get

A business valuation expert is a credentialed professional who produces a defensible written opinion of value on a privately held company, an ownership interest, or an intangible asset, and who is willing to sign their name to that opinion and defend it under cross-examination, before the IRS, before a bankruptcy judge, before an SBA loan committee, or across the table from a buyer’s quality of earnings team. The credential is what separates an opinion of value from a guess, and the willingness to defend the report is what separates a report worth paying for from a report that will collapse the first time someone with skin in the game pushes back.

Most owners hire one of these professionals exactly once, usually under stress, and usually without a clear picture of what they are buying. This guide walks through what a valuation expert actually does, the five trigger events that demand one, the four credentials that matter, realistic 2026 fee ranges, the difference between an SBA-compliant report and a tax-court-defensible report, and the questions to ask before you sign an engagement letter. Sources include the Uniform Standards of Professional Appraisal Practice (USPAP), IRS Revenue Ruling 59-60, the SBA SOP 50 10 7.1, the American Society of Appraisers, NACVA, the AICPA ABV credential, the CFA Institute, and active practitioners including Trugman Valuation, Pluris Valuation Advisors, and Mercer Capital.

What a Business Valuation Expert Actually Does

A credentialed valuation professional produces three deliverables: a written report of value, a defense of the methodology used, and a sworn willingness to testify or attest to the conclusion if challenged. Everything else is supporting work. The report itself follows a defined structure under USPAP Standard 9 and Standard 10, which are the rules governing the development and reporting of a business or intangible asset appraisal as published by the Appraisal Foundation. The full standards text is hosted at the USPAP standards page.

The work typically begins with a kickoff call, a signed engagement letter that defines the standard of value (fair market value, fair value, investment value, or intrinsic value), the premise of value (going concern or liquidation), the effective date of value, the intended user, and the intended use. These five definitions control everything that follows. A report written for an estate tax filing under IRS Form 706 is not the same report as one written for a divorce in Texas or a buy-sell trigger in Delaware, even if the subject company is identical.

After the engagement letter, the expert collects financial statements (typically five years), tax returns, the corporate ledger, the cap table, customer concentration data, the lease, any material contracts, and a management questionnaire. They interview the owners. They normalize the financials by adding back owner compensation in excess of market, personal expenses run through the business, one-time legal or settlement costs, and any non-operating assets or liabilities. The normalized number is what the valuation runs against, not the tax return as filed.

The expert then applies one or more of the three accepted valuation approaches: the income approach (discounted cash flow or capitalized cash flow), the market approach (guideline public company method or guideline transaction method), and the asset approach (adjusted net asset method). Most credible reports use at least two approaches and reconcile them. The reconciliation, not the math, is where the expert earns the fee. Aswath Damodaran at NYU Stern publishes the industry betas and equity risk premium data that most income approach models depend on, accessible at the Damodaran online data archive. Practitioners also rely on the Kroll Cost of Capital data service for size premia and industry risk premium inputs.

The output is a signed report, typically 60 to 150 pages, with exhibits showing the comparable transactions, the discount rate buildup, the discounts for lack of marketability and lack of control, the sensitivity analysis, and the certification page where the expert attests under USPAP that the work was performed without contingent compensation and without a predetermined conclusion.

When You Need a Business Valuation Expert vs a Calculator

Free online business valuation calculators answer a different question than a business valuation expert does. The calculator gives you a directional number based on a revenue multiple or an EBITDA multiple pulled from a generic database. That number is fine for a back-of-envelope estimate, a curiosity check, or a conversation with a spouse about whether the business is worth selling.

The calculator is useless the moment someone with authority over your money or your taxes asks “who signed that and what is their credential.” The IRS does not accept calculator output. SBA lenders do not accept calculator output. Divorce court does not accept calculator output. Buy-sell triggers among partners do not accept calculator output. A buyer’s quality of earnings advisor at a private equity firm will laugh at calculator output.

The threshold question is simple. If the number will be used inside your own head, a calculator is fine. If the number will be used by anyone else, including a lender, a court, a tax authority, a partner, a spouse, an heir, or a buyer, you need a credentialed expert with a signed report. Our companion guide on business valuation services cost walks through the price spread between the two tiers in detail, and the how to price a business for sale guide shows where calculator output fits in the early discovery stage of a transaction.

The Five Trigger Events That Require an Expert Opinion

Five trigger events account for the majority of paid valuation engagements in 2026. Each has its own evidentiary standard, its own intended user, and its own preferred credential. The order below is rough frequency for engagements under $5 million in enterprise value.

• Sale or purchase of a privately held business
• Divorce, estate settlement, or litigation
• SBA 7(a) loan compliance for a business acquisition
• Tax filings including charitable gifts, estate returns, and gift tax returns
• Buy-sell agreement activation among owners

The trigger determines the standard of value, which determines the credential, which determines the price. Mixing these up is the single most common mistake owners make. Hiring a tax-credentialed expert to defend a divorce valuation in a community property state, or hiring a litigation-track expert to file a Form 706 attachment, produces a report that costs more than it should and persuades less than it should.

Trigger 1: Sale of a Business (Sell-Side Valuation)

A sell-side valuation is the most common reason an owner hires this type of professional. The intended use is to set an asking price, to brief an investment banker or business broker, to defend the price during negotiation, and to anchor the seller’s expectations before a letter of intent arrives. The standard of value is usually fair market value, sometimes investment value when a strategic buyer is in play.

Sell-side valuations differ from tax or litigation work in one important way: the audience is commercial, not legal. The report needs to survive a quality of earnings review and a buyer’s confirmatory due diligence, but it does not need to survive cross-examination in tax court. That means the discount rate buildup can be shorter, the comparable transaction set can be broader, and the report itself can run 40 to 80 pages instead of 120 plus.

Mercer Capital, Trugman, and Pluris all publish material on the methodology used for owner-occupied small business sell-side work. The typical model triangulates an income approach DCF with a market approach using SDE multiples for businesses under $2 million in EBITDA and EBITDA multiples for businesses above $2 million. The expert produces a value range, not a point estimate, because the market itself produces a range. The football field valuation chart guide shows how that range gets presented to a board or owner group.

The work also includes a quality of earnings preview. Buyers run their own quality of earnings analysis, but the seller’s expert flags the items that are likely to come up: customer concentration, owner add-backs that may not survive scrutiny, deferred maintenance on equipment, working capital normalization, and any related party transactions. Catching these on the sell side before the buyer does saves the seller real dollars at closing. The relationship between EBITDA and the working capital adjustment is detailed in the EBITDA meaning explained guide and the amortization in EBITDA walkthrough.

Investment bankers run a different but parallel process. The how investment bankers value a business guide compares the two, and the enterprise value equation piece covers the bridge from equity value to enterprise value that any sell-side report has to walk through.

Trigger 2: Divorce, Estate, and Litigation

Divorce, estate, and shareholder litigation produce the second-largest category of paid engagements. The intended user is a court. The intended use is to support a finding of fact about value. The standard of value depends on the jurisdiction. Most divorce cases use fair market value, but several states (Connecticut, New Jersey, New York) use fair value, which excludes the discount for lack of marketability. Reading the wrong standard into a divorce report is malpractice and a frequent source of expert disqualification.

The expert in a litigation engagement is hired by counsel, not by the party. The work product is privileged. The report goes through a Daubert challenge in federal court or a Frye challenge in some state courts. The expert sits for deposition. The expert testifies at trial. A litigation-track valuation expert charges a multiple of what a transactional expert charges because the work itself is multiplied: the report has to be written twice (once for production, once for testimony), the methodology has to survive opposing expert critique, and the schedule is set by the court, not by the client.

Practitioners with deep litigation track records include Trugman Valuation, Mercer Capital’s litigation group, and several boutiques organized through Business Valuation Resources (BVR). The BVR conference circuit and the BVR DLOM Toolkit for discount for lack of marketability work are the de facto standards in litigation valuation.

Shareholder dissent and oppression cases are a third subcategory. Delaware Chancery Court uses fair value under the Delaware General Corporation Law Section 262. The fair value standard excludes both the marketability discount and the minority discount, which can move the final number 30 to 50 percent above what fair market value would produce on the same facts.

Trigger 3: SBA 7(a) Loan Compliance

The SBA requires an independent third-party business valuation for any 7(a) acquisition loan over $250,000 when there is a change of ownership, and for any loan involving a goodwill component. The current rule lives in SOP 50 10 7.1, effective in 2025 and carried forward into 2026, which replaced the prior SOP 50 10 6 framework.

SBA valuation work has a specific intended user (the lender), a specific intended use (loan underwriting), and a specific compliance checklist. The expert must be a “qualified source” under the SOP, which means one of four credentials: ASA from the American Society of Appraisers, CBA or ABAR from the Institute of Business Appraisers, CVA or AVA from NACVA, or ABV from the AICPA. A CFA is not on the SBA list and cannot sign an SBA-compliant report unless paired with one of the four.

The report has to address the SBA-specific elements: a goodwill identification and reasonableness check, a separate allocation of purchase price across tangible and intangible assets, and a debt service coverage feasibility analysis that ties the proposed loan to the projected cash flow. The lender’s credit committee uses the report as one of the inputs into the loan approval decision. The seller does not see the SBA report, the buyer does not direct it, and the expert reports to the lender even though the buyer pays for it.

SBA reports are commoditized. Most run $3,000 to $7,500 for a deal under $5 million, with turnaround times of two to three weeks from receipt of all documents. The lender often has a preferred panel of three to five firms who already understand the bank’s documentation standards. Going outside the panel is allowed but adds friction. The business acquisition guide covers where the SBA report sits in the broader deal timeline.

Trigger 4: Tax Court (IRS Form 706, 8283, Estate Returns)

Tax-driven valuation engagements are the most technically demanding category. The intended user is the IRS. The intended use is to support a number on a federal tax return. The evidentiary standard is set by Revenue Ruling 59-60, the 1959 ruling that remains the foundational standard for fair market value of closely held stock for federal tax purposes. Every tax valuation report cites it. Every tax court opinion turns on it.

Revenue Ruling 59-60 lists eight factors the IRS expects every fair market value analysis to address: the nature and history of the business, the economic outlook of the industry, the book value and financial condition, the earning capacity, the dividend-paying capacity, goodwill or other intangible value, prior sales of stock, and the market price of comparable public companies. A report that does not visibly address all eight gets challenged. A report that addresses them in a checklist style without analysis also gets challenged.

Three IRS forms drive most tax valuation work:

• Form 706, the United States Estate (and Generation-Skipping Transfer) Tax Return, requires a qualified appraisal of any closely held business interest included in the gross estate above the filing threshold. The 2026 estate exclusion remains at the post-TCJA level pending congressional action.
• Form 709, the United States Gift Tax Return, requires a qualified appraisal of any gifted business interest over the annual exclusion amount.
• Form 8283, Noncash Charitable Contributions, requires a qualified appraisal for any donated business interest over $5,000 and a signed appraiser declaration over $500,000.

The IRS defines a “qualified appraiser” in Treasury Regulation 1.170A-17. The definition requires a recognized appraisal designation, regular work in the discipline, and no disqualifying relationship to the donor or property. The penalty for using a non-qualified appraiser on a charitable gift is the disallowance of the deduction. The penalty for a “gross valuation misstatement” under IRC Section 6662 is 40 percent of the underpayment.

Tax court has its own jurisprudence. Cases like Estate of Mitchell, Mandelbaum, and the Bernard Mandelbaum DLOM framework define how marketability discounts get analyzed. A tax-track expert reads these cases the way a litigator reads case law. The AICPA ABV and the ASA BV tracks both spend significant continuing education hours on tax court developments.

Trigger 5: Buy-Sell Agreement Activation Among Owners

Buy-sell agreements among partners or shareholders frequently call for a valuation upon a trigger event: death, disability, divorce, departure, or dispute. The agreement either names a specific formula, names a specific firm, or names a process (typically each side picks an appraiser, the two appraisers pick a third, and the average or median controls).

The valuation expert in a buy-sell engagement reads the operating agreement or shareholder agreement first, before touching the financials. The agreement defines the standard of value (often fair market value with explicit instructions on whether discounts apply), the effective date (often the date of the trigger event, not the date of the report), and any formula adjustments. Many older buy-sell agreements use formulas that no longer produce a credible number (book value, three times trailing net income, a fixed amount last updated in 2008). The expert has to either apply the formula as written or flag the disconnect for counsel.

Buy-sell valuation work is contentious by design. The owner being bought out wants a high number. The owners doing the buying want a low number. The expert sits in between. A well-drafted buy-sell calls for a “neutral” or “stipulated” expert chosen jointly. A poorly drafted one produces three competing experts and a fight. Mercer Capital has published extensively on buy-sell agreement design and the Mercer buy-sell process is widely cited.

The Four Valuation Expert Credentials (ASA BV, NACVA CVA, AICPA ABV, CFA)

Four credentials dominate the field. Each has a different parent body, a different curriculum, a different ethics framework, and a different typical practitioner background. A serious business valuation expert holds at least one of these. Many hold two or three.

The American Society of Appraisers ASA designation in Business Valuation is the most rigorous and the longest standing among the four. The five-year experience requirement is enforced. The peer review process screens for quality. ASA members are the most common expert witnesses in tax court and federal litigation.

The NACVA CVA designation is the most operationally focused. NACVA’s training emphasizes the practical mechanics of SBA reports, divorce valuations, and owner-operator sell-side work. CVAs are the largest single population of credentialed valuation experts in the United States.

The AICPA ABV designation requires an active CPA license as a precondition. ABVs come from a tax and audit background and dominate the financial reporting valuation category (ASC 805 purchase price allocations, ASC 350 goodwill impairment, ASC 718 stock compensation).

The CFA Institute charter is the most generalist of the four. CFAs work across public equities, fixed income, derivatives, and private market valuation. A CFA without a paired BV-specific credential is uncommon in pure business valuation work but very common in fund-level NAV and complex security valuation.

Credential Differences and Why They Matter

The credential controls four things: who will accept the report, what discount the expert can defend, how long the work takes, and what the engagement costs. Picking the wrong credential for the trigger event is the most expensive procedural mistake an owner can make.

For SBA work, any of the four named credentials (ASA, CVA, CBA, ABV) is acceptable to the SBA. The CFA alone is not. For tax court, the ABV and ASA are the most frequently accepted. For divorce in a state that follows fair value, the ASA or a CVA with documented divorce experience is the safer choice. For ESOP work under DOL fiduciary standards, an ASA or ABV with documented ESOP experience is effectively required.

The credential also controls what the expert can say about discounts. The discount for lack of marketability (DLOM) on a non-controlling interest in a closely held company typically ranges from 15 percent to 40 percent. The discount for lack of control typically ranges from 10 percent to 25 percent. A credentialed expert defends a specific number within those ranges using documented methodology (Mandelbaum, Quantitative Marketability Discount Model, restricted stock studies, pre-IPO studies). An uncredentialed person picking a number from a range gets shredded in deposition.

The expert’s continuing education record matters as much as the credential itself. Ask for the last 24 months of CPE. A litigation-track expert should have hours in deposition preparation, expert witness testimony, and recent case law. A tax-track expert should have hours in current IRS rulings, tax court opinions, and Treasury Regulation updates. A transactional expert should have hours in current transaction multiples, industry-specific outlook, and quality of earnings methodology.

Business Valuation Expert Cost: Realistic 2026 Ranges

The fee depends on the report type, the company complexity, the deadline, and the credential of the signing expert. Below are realistic 2026 ranges from a survey of practitioners across NACVA, ASA, and AICPA membership rolls, cross-referenced against published rate cards from Mercer Capital, Trugman, and Pluris.

The single biggest fee driver inside any category is complexity. Multiple entities, multiple classes of equity, international operations, customer concentration above 25 percent, related party transactions, recent acquisitions, deferred maintenance, regulatory exposure, and pending litigation all push the fee toward the top of the range. A clean single-entity service business with audited financials and no related party items will land at the bottom of the range.

Rush work adds 25 to 50 percent. A two-week SBA report compressed into five business days costs more because the analyst has to push everything else aside. Tax filing deadlines (April 15, the extended deadline of October 15, the nine-month estate filing window) produce predictable surge pricing every year.

The fee for testimony is separate from the fee for the report. Most litigation experts bill the report on a fixed fee and the testimony on an hourly rate (typically $400 to $850 per hour for deposition and trial time, plus travel). Daubert challenges, opposing expert rebuttals, and second reports also bill hourly. A litigation budget should assume the report fee plus an equal amount in hourly time for the matter to reach trial.

SBA-Compliant vs USPAP-Compliant vs Tax-Court Defensible Reports

Three compliance frameworks dominate. They overlap but are not interchangeable. An SBA-compliant report may or may not be tax-court defensible. A USPAP-compliant report may or may not satisfy the SBA. A tax-court report almost always satisfies USPAP but may exceed what the SBA actually wants to read.

USPAP, the Uniform Standards of Professional Appraisal Practice, is the baseline ethics and process standard published by the Appraisal Foundation. It applies to all appraisal disciplines including real estate, personal property, and business valuation. Standards 9 and 10 cover business valuation development and reporting. ASA members are required to comply with USPAP. NACVA members may comply with USPAP or with NACVA’s own standards (which are USPAP-aligned). ABVs comply with the AICPA SSVS-1 Statement on Standards for Valuation Services.

The SBA requires the expert to comply with the recognized professional standards of the expert’s organization. In practice that means USPAP or SSVS-1. SOP 50 10 7.1 also adds specific content requirements that go beyond either standard: a separate goodwill allocation, a debt service coverage analysis, and a confirmation that the expert is not related to the buyer, seller, or referral source.

Tax court defensibility is a higher bar. The report has to track Revenue Ruling 59-60 explicitly, address every factor listed in the ruling, document every comparable transaction by name and source, explain every adjustment to financials, and produce a discount rate buildup that a forensic expert from the IRS Engineering and Valuation Program can attack and the report can defend. Tax court reports often run 150 pages with another 50 pages of exhibits. They are written knowing that the IRS will hire its own credentialed expert to write the opposing report.

The practical translation: do not buy an SBA report and reuse it for an estate filing six months later. The standard of value, the intended user, and the documentation depth are different. The IRS will see that the report was written for a lender, will treat it as not credible for estate purposes, and the taxpayer will end up paying for two reports plus penalty exposure.

How to Vet a Business Valuation Expert: The 10 Questions

The vetting conversation should take 45 minutes on the phone before any engagement letter gets signed. The expert should expect these questions and should answer them directly. Hesitation, deflection, or vague answers on any of them is a signal to keep looking.

1. What is your primary credential and how long have you held it? Ask for the credential number and the date of issuance. Both are verifiable on the issuing organization’s public roster.
2. How many reports of this exact type (SBA, sell-side, estate, divorce, litigation) have you signed in the last 24 months? An expert doing one estate report a year is not the right pick for an estate. An expert doing 40 SBA reports a year is the right pick for an SBA loan.
3. Who will actually do the work and who will sign the report? Boutique firms have the credentialed expert doing the work. Larger firms often have associates doing the work and a partner signing. Both can produce good work, but you need to know.
4. What is the engagement letter scope, what is included, and what triggers a change order? Ambiguity on scope produces surprise invoices.
5. What standard of value will you apply and why? The expert should be able to explain the choice in plain language with reference to the intended use.
6. What approaches will you use and how will you reconcile them? A report relying on a single approach is weaker than a report reconciling two or three.
7. Have you been challenged on a similar report? How was it resolved? Experts with no challenge history may simply be early in their careers. Experts with multiple unsuccessful defenses are a problem.
8. What is your turnaround time from receipt of all documents to final report? Hold the expert to a date in writing.
9. What is your fee, what is hourly, what is fixed, and what is the cap? Get the cap in writing.
10. Will you sign the report yourself, will you appear if challenged, and is there any contingency in your compensation? The answer to the contingency question must be “no” under USPAP. A “yes” disqualifies the expert.

References from clients in the same industry and the same engagement type are also fair to request. Reference checks should focus on the expert’s responsiveness, the quality of the final report, and whether the expert’s number held up under negotiation or scrutiny.

Red Flags That Should Make You Walk Away

Several patterns reliably predict a bad outcome. Any one of them is enough reason to keep looking. Multiple together is the closest thing to a guarantee that the report will fail when challenged.

• Contingent compensation tied to the value conclusion. A USPAP violation, full stop.
• Predetermined value conclusion or willingness to “get to” a target number. Another USPAP violation.
• Refusal to disclose the credential number or refusal to send a sample redacted report.
• Unwilling to sign the report personally. Reports signed only by the firm and not by an individual are a sign of liability avoidance.
• Fee quoted without an engagement letter or a written scope.
• Turnaround time that is faster than reasonable for the report type. A two-day estate valuation is not credible.
• No published methodology, no sample exhibits, no continuing education record.
• Discount conclusions outside the defensible range (DLOM above 50 percent or below 10 percent on a typical closely held interest without specific facts to support it).
• Reports built from a template with no customization to the subject company.
• Use of comparable transactions from databases the expert cannot name or document.

One more red flag: the expert who badmouths every other expert by name. The field is small. Credible practitioners disagree on methodology and discount levels in writing, in published articles, and in court testimony. They do not run down competitors in a sales call. That behavior is a signal of insecurity, not expertise.

How CT Acquisitions Works With Business Valuation Experts

CT Acquisitions is a private equity buyer of profitable, owner-operated businesses with EBITDA between $1 million and $25 million. Every transaction includes a valuation step. Sometimes the seller brings their own credentialed report. Sometimes the seller brings a calculator print-out and a number from their CPA. Sometimes there is no number at all and the conversation starts at zero.

The right valuation professional at the right stage of a deal saves the seller money and accelerates the close. The wrong expert at the wrong stage stalls the deal or kills it. The pattern that works most often: a credentialed sell-side opinion early enough to anchor the asking price, an SBA-compliant report if the buyer is using SBA financing, and a separate tax-driven valuation if the transaction structure produces a 706 or 709 filing obligation. Three reports, three intended users, three sets of credentials.

Owners considering a sale should obtain a credentialed sell-side opinion before signing a letter of intent. The cost is 7,500 to 15,000 dollars. The protection is that the seller knows the range and can defend it. Sellers who skip this step and accept the first buyer’s number frequently leave 15 to 30 percent of enterprise value on the table. The math on a 5 million dollar business at a 20 percent leakage is a million dollars, against an avoidable 10,000 dollar fee.

CT Acquisitions does not provide the valuation report itself. We are the buyer. The seller needs an independent expert whose duty runs to the seller. We will, however, accept a credentialed sell-side report into our underwriting process and will pay for our own confirmatory valuation work if the seller’s report is from a recognized firm.

Business Valuation Expert: Frequently Asked Questions

How long does a business valuation report take to produce?

A standard sell-side or SBA report takes 2 to 5 weeks from receipt of all documents to delivery of the signed final report. The variable is document completeness on the front end. Owners who can produce five years of financials, tax returns, customer concentration data, a cap table, and the lease in the first week shorten the timeline by two weeks compared to owners who deliver documents in trickles. Tax and litigation reports run 4 to 16 weeks because the documentation depth, the citation work, and the internal review are all heavier.

Can I use one valuation report for multiple purposes?

Sometimes, but not often. The intended user and intended use define the report. A sell-side report addressed to the owner cannot be used for an estate filing addressed to the IRS without a re-issuance, a new engagement letter, and often new analysis at a new effective date. An SBA report addressed to a lender cannot be used by an opposing party in divorce because the seller is not the intended user. Ask the expert to write the report addressed to multiple intended users if you can predict the secondary use at the time of engagement. Adding a use later usually requires a new report.

What is the difference between a calculation of value and a conclusion of value?

A calculation of value is a limited scope engagement where the expert applies procedures agreed with the client, not a full set of valuation procedures the expert would otherwise apply. The output is a calculated value, not a conclusion. A conclusion of value is the full scope engagement under USPAP or SSVS-1, including the development of all relevant approaches. Calculations cost less, take less time, and are appropriate for internal planning. Conclusions are required for any external user with consequence (IRS, court, lender, buyer).

Do I need a separate valuation for each shareholder class?

If the company has multiple classes of equity (preferred, common, options, warrants) with different economic rights, yes. The expert produces an enterprise value first, then allocates it across the classes using an option pricing method, a probability weighted expected return method, or a current value method. The choice of allocation method depends on the company stage, the rights of each class, and the intended use. Cap table complexity is a primary driver of fee.

What is a quality of earnings analysis and is it the same as a valuation?

A quality of earnings analysis tests whether reported EBITDA is sustainable, recurring, and reliable. It is an accounting and operational diagnostic, not a value opinion. A buyer’s quality of earnings advisor produces a normalized EBITDA number that the buyer then uses in their own valuation. A seller’s valuation expert often produces a preview quality of earnings analysis as part of the sell-side report, but the formal quality of earnings work is typically commissioned separately by the buyer.

Are online valuation calculators ever good enough?

For directional thinking, yes. For any external user, no. Calculators apply a generic multiple to a generic input. They do not normalize earnings, do not adjust for customer concentration, do not address discounts, do not document methodology, and are not signed by a credentialed person. They have no defense if challenged. The right use case is the back-of-envelope estimate that tells an owner whether the conversation is worth starting.

Can my CPA do my business valuation?

Only if your CPA holds the ABV credential, the CVA credential, or another recognized business valuation designation, and only if the work is within the CPA’s specific experience. A general practice CPA without a valuation credential is not a qualified appraiser under IRS standards, cannot sign an SBA-compliant report, and is unlikely to survive litigation cross-examination. CPAs frequently quarterback the relationship between the owner and a separate credentialed valuation expert, which works well.

Does the IRS audit business valuations?

Yes, through the IRS Engineering and Valuation Program. Estate and gift tax returns with closely held business interests draw audit attention, and the audit usually includes a re-valuation by an IRS-employed valuation expert. The taxpayer’s report has to defend itself against that re-valuation. Reports that follow Revenue Ruling 59-60 carefully, cite recent tax court cases, and document every adjustment win these challenges more often than reports that do not.

How often should I update my business valuation?

For ESOP plans, annually, as a fiduciary requirement under ERISA. For buy-sell agreements, the document itself usually specifies a refresh interval (often annually or every two years). For sale planning, a fresh opinion 12 to 18 months before going to market is the right cadence, with an update at the time of marketing. For estate planning, a fresh opinion every three to five years tracks well unless a material event triggers an earlier refresh.

What happens if the buyer disagrees with my valuation report?

Negotiation happens. A credentialed sell-side report sets the seller’s anchor and documents the methodology. The buyer’s own analysis sets a different anchor. The two sides argue through the differences (typically the discount rate, the comparable set, the add-back schedule, and the working capital target) until a price emerges. The sell-side report does not bind the buyer. It does, however, force the buyer to articulate specific reasons for any number below the report, which usually moves the negotiation toward the seller. Sellers without a credentialed report negotiate from no anchor and end up with the buyer’s number.
