Key Takeaway: An earnout file should let both parties reproduce the payment calculation and explain its accounting and tax treatment. Preserve the signed formula, measurement records, permitted adjustments, review deadlines, payment evidence, and tax allocations. Contractual earnings, book income, cash received, and taxable gain are separate amounts.

An earnout makes part of a business-sale payment depend on later performance or another agreed condition. The most useful preparation is to test the formula before signing and establish who will produce the supporting records after closing. A provision referring only to “profits” can leave major questions about revenue timing, overhead, owner compensation, and transaction costs unresolved.
Define the formula and the records needed to test it
Transaction counsel and the accounting advisers should resolve these items together in the agreement and its schedules:
- Metric and period: Define revenue, EBITDA, customer retention, or the specific milestone; identify the covered business, start and end dates, currency, and treatment of partial periods.
- Accounting hierarchy: State which explicit contract rules, agreed historical practices, and accounting framework control, and in what order. Resolve revenue cutoffs, returns, bad debts, reserves, and changes in estimates.
- Permitted adjustments: Specify owner-pay normalization, transaction and integration costs, overhead and intercompany allocations, new acquisitions, discontinued operations, and any earnout-related accounting charges.
- Payment mechanics: Set the threshold, rate or multiple, floor, cap, carryforwards or catch-up features, interest, offsets, and cash, share, or note settlement terms.
- Operating and review provisions: Address post-closing operating covenants, access to information, delivery and objection deadlines, disputed versus undisputed payments, and the dispute-resolution process.
Keep an agreed sample calculation with the executed documents. Test a below-threshold outcome, an ordinary outcome, and a capped outcome. A spreadsheet should implement the signed terms, not silently fill gaps in them.

A worked example: from book earnings to the payment
Assume a hypothetical agreement pays 50% of adjusted EBITDA above $500,000 for one measurement year, with a $200,000 cap and a zero floor. EBITDA means earnings before interest, taxes, depreciation, and amortization, subject to the agreement’s specific definition. Here, the parties expressly permit two additional adjustments: $20,000 of identified transaction costs and $30,000 of owner compensation above an agreed benchmark.
| Step | Amount | Evidence |
|---|---|---|
| EBITDA reconciled from the books | $650,000 | Financial statements and ledger reconciliation |
| Add permitted transaction costs | $20,000 | Contract clause and invoices already included in earnings |
| Add permitted compensation adjustment | $30,000 | Agreed benchmark and payroll support |
| Adjusted EBITDA | $700,000 | $650,000 + $20,000 + $30,000 |
| Amount above the threshold | $200,000 | $700,000 − $500,000 |
| Earnout before the cap | $100,000 | $200,000 × 50% |
| Earnout payable under the formula | $100,000 | Lesser of $100,000 and the $200,000 cap |
At $480,000 adjusted EBITDA the payment is zero. At $950,000 it is capped at $200,000, even though 50% of the $450,000 excess is $225,000. These are invented terms, not market standards. The adjustments are allowed only because this example’s agreement authorizes them; they do not establish tax deductibility or justify deleting expenses from the general ledger.
Revenue is not necessarily cash collected. If accrual revenue is $1,000,000, opening receivables are $100,000, and closing receivables are $150,000, collections are $950,000, assuming no write-offs, credits, advances, or other receivable movements. The agreement must specify whether the metric uses revenue or collections. EBITDA also does not equal spendable cash after debt payments, capital purchases, and working-capital changes.
For a sample review timetable, the agreement might require the buyer’s calculation within 60 days after year-end and a seller objection within 30 days after receipt. Those are contractual examples, not statutory deadlines. Define required supporting information, delivery and receipt rules, notice recipients, and what happens when records are incomplete. Keep proof of delivery and calendar the actual signed deadlines.
Determine what each payment represents for tax purposes
Identify whether the transaction sells assets, corporate shares, or partnership interests, and whether an election or disregarded-entity treatment changes that characterization. Separate purchase price from employment or consulting compensation, interest, rent, restrictive-covenant payments, and other obligations. Internal Revenue Code section 61 separately includes compensation, business income, property gains, and interest in gross income; calling all of them an “earnout” does not make them capital gain.
Keep employment and consulting agreements, service requirements, forfeiture clauses, valuation support, and payment allocations with the sale documents. Where a payment is compensation, analyze worker status and the applicable payroll, withholding, and reporting rules. Do not move employee compensation outside payroll merely because it appears in the purchase agreement. Book classification is relevant evidence but does not itself determine the tax answer.
For an eligible installment sale, purchase-price payments generally include taxable gain and basis recovery, with interest considered separately. Inventory and depreciation recapture have important exceptions to deferral; an asset sale must be analyzed by asset. Private-company shares may qualify, while publicly traded stocks and securities generally do not. See IRS Publication 537 on installment eligibility, recapture, and interest.
When total selling price remains contingent, basis recovery follows special rules. A determinable maximum selling price generally drives the initial gross-profit computation; a fixed payment term without a determinable maximum uses different allocation rules. Later reductions and interest can require recomputation. Do not apply a fixed-price percentage or deduct all remaining basis from the first earnout without analysis. See Treasury Regulation 15a.453-1(c). Preserve the tax calculation for every payment year, including prior payments and basis already recovered.
For a qualifying taxable acquisition of a business’s assets, both buyer and seller generally report allocation on Form 8594. Later consideration changes may require a supplemental statement for the affected year. Do not automatically allocate an additional payment entirely to goodwill or assume every equity sale requires this form. See the Form 8594 instructions on filing and allocation changes.
Keep financial-statement accounting separate
For a buyer applying the acquisition method to a U.S. GAAP business combination, qualifying contingent consideration is initially recognized at acquisition-date fair value. Liability or asset classifications generally require remeasurement at each reporting date, with changes in earnings, subject to the applicable hedge exception. Equity-classified consideration is not subsequently remeasured and is settled within equity. Qualifying measurement-period adjustments for acquisition-date facts are treated separately from later performance changes. These rules appear in ASC 805-30-25-5 and 35-1, reproduced in DART.
For example, assume an ordinary cash earnout liability previously measured at $80,000 increases to $100,000 because of post-acquisition performance. With no measurement-period or hedge exception, the buyer debits remeasurement loss $20,000 and credits the liability $20,000. When the $100,000 is paid, debit the liability $100,000 and credit cash $100,000. Do not expense the full payment again. This simplified example excludes the initial acquisition entry and tax effects.
Automatic forfeiture upon employment termination is a significant distinction: ASC 805-10-55-25(a) treats that arrangement as compensation for postcombination services. See the reproduced ASC guidance on payments to selling shareholders who become employees. Review the actual terms and their substance.
First establish whether the accounting is for a business combination, an asset acquisition, a seller’s disposal, or another arrangement. The buyer’s ASC 805 example is not a universal entry for the seller or for tax-basis books. Preserve a separate accounting memorandum, valuation inputs, revisions, and reconciliations between book and tax amounts.
Confirm entity status without letting it replace transaction analysis
An LLC is a state-law form. For federal income tax, a domestic single-member LLC generally is disregarded and a domestic LLC with two or more members generally is a partnership, unless an election changes classification. Corporate taxation, including an eligible S election, is a separate question. A disregarded LLC’s activity belongs on its owner’s appropriate return; that owner need not be an individual. A partnership generally files Form 1065 and provides partner information, while owners report under the rules applicable to them. See IRS LLC classification guidance.
An S corporation generally files Form 1120-S and provides shareholder K-1s; certain built-in gains and passive income can produce entity-level tax. Review shareholder eligibility, the one-class-of-stock requirement, and any proposed ownership change. A sale to an ineligible shareholder can terminate S status, and a last-minute election does not erase prior C-corporation built-in gain exposure. See IRS S-corporation requirements and the Form 2553 timing and eligibility instructions.
Maintain one indexed transaction file
| File section | Core records | Responsible party |
|---|---|---|
| Executed deal | Agreement, schedules, amendments, closing statement, formula examples, employment and other side agreements | Each party and its counsel retain executed copies |
| Measurement support | Ledger, statements, customer contracts, invoices, payroll summaries, allocation policies, bank and receivable reconciliations | Buyer’s finance team prepares; seller reviews within agreed access rights |
| Calculation and review | Versioned workbook, adjustment evidence, delivery records, objections, responses, resolution | Each side retains what it prepares and receives |
| Accounting and tax | Valuations, classification memoranda, entries, asset or equity basis, installment schedules, allocations and filed forms | Each party and its advisers maintain their own reporting support |
| Settlement | Approved calculation, interest computation, payment instructions and confirmations, releases or outstanding claims | Buyer and seller reconcile payment against the obligation |
Retention is governed by applicable tax, payroll, contractual, and other legal obligations. Generally preserve property records through disposition and the related tax limitations period; employment-tax records require at least four years after tax is due or paid, whichever is later. See IRS record-retention guidance. Counsel should also address litigation-preservation duties and any hold that prevents routine disposal.
Have counsel define confidentiality, privilege, redaction, and permitted disclosure before exchanging drafts, legal advice, customer data, or employee information. Review rights do not automatically permit unrestricted access to every record. Retain required originals and a log of the material actually shared.
For a planning discussion with CPA Firm South Florida’s client team, bring the proposed deal structure, draft earnout terms, financial records, and basis schedules. Confirm the accepted scope and fees for tax modeling, accounting, valuation, calculation review, and dispute assistance. Ordinary return preparation does not establish that those transaction services are included.
Frequently asked questions
Is every earnout payment capital gain?
No. Determine what each amount pays for. Purchase-price gain, recovery of basis, interest, employment compensation, and other arrangements can receive different treatment. The earnout label does not decide the result.
Does a share sale use the same allocation as an asset sale?
Not automatically. Identify the legal sale and its tax treatment, including any applicable deemed-asset-sale election. A partnership-interest sale or disregarded-entity transfer also requires its own analysis.
Related reading: “Asset Purchase vs. Equity Purchase: Accounting Questions for Buyers” covers Asset Versus Equity Purchase in more detail.
Can the buyer’s reported earnings be used directly in the formula?
Only if they match the agreement’s metric and accounting definitions. Reconcile approved adjustments to the ledger and keep the original financial statements intact.
Should the business make an S election immediately before sale?
Do not assume that an election improves the sale. Review eligibility, effective dates, purchaser ownership, prior C-corporation history, and the complete transaction before signing.
How long should the earnout file be kept?
Keep it through all payment and dispute periods and the applicable tax and other legal retention periods. Property-basis support may be needed until disposition and expiration of the related limitations period.
