How is an earnout taxed when I sell my business?
Timing depends on the installment rules; character depends on substance
An earnout paid in a year after the sale is generally reported under the installment method of IRC §453, which applies automatically unless you elect out. Temporary Treas. Reg. §15a.453-1(c) sets how basis is recovered when the price is contingent. Part of each deferred payment may be treated as interest under §483 or §1274. If the earnout is really pay for your future services, it is compensation, taxed as ordinary income.

Key takeaways
- The installment method applies automatically to a sale with payments after the year of sale unless you elect out (§453(d)).
- With a stated maximum price, gain is computed as if the maximum will be paid; if less is paid, the difference is generally recovered later.
- Depreciation recapture in an asset sale is taxed in the year of sale, even if the cash comes later (§453(i)).
- Part of each deferred payment can be recharacterized as interest, which is ordinary income.
- Payments tied to your continued employment are likely compensation, not sale price.
What it is
An earnout is a promise to pay additional purchase price if the business reaches agreed targets after closing, usually revenue or earnings over one to three years. Earnouts bridge valuation gaps between buyers and sellers.
Two tax questions arise. The first is timing: when is the earnout taxed? The second is character: is it part of the sale price (usually capital gain) or payment for services (ordinary income)?
What the law says
IRC §453(c) defines the installment method as a method under which income recognized each year is the proportion of the payments received that year that the gross profit bears to the total contract price. Under §453(d), the method applies unless the seller elects out on a timely filed return. Section 453(b)(2) excludes dealer dispositions and inventory, and §453(k)(2) excludes sales of stock or securities traded on an established securities market.
Temporary Treas. Reg. §15a.453-1(c) covers contingent payment sales. If the agreement has a stated maximum selling price, the gross profit ratio is computed by assuming the maximum will be paid. If there is no maximum but payments are limited to a fixed period, basis is recovered in equal annual amounts over that period. If neither limit exists, basis is generally recovered over 15 years, subject to the question of whether a sale has really occurred.
Sections 483 and 1274 treat part of a deferred payment as interest if the contract does not provide adequate stated interest. Section 453(i) requires recapture income to be reported in the year of sale, and §453A imposes an interest charge on the deferred tax for certain installment obligations when the face amount of such obligations arising in the year and outstanding at year-end exceeds $5,000,000.
Requirements and tests
Check each of these:
- At least one payment is received after the year of sale.
- The property sold is not inventory or dealer property, and is not publicly traded stock or securities.
- Whether the earnout has a stated maximum, a fixed payment period, or neither.
- Whether the contract states adequate interest on deferred payments.
- How much of the gain is depreciation recapture that must be reported in the year of sale.
- Whether the earnout depends on the seller's continued employment or services.
- Whether total installment obligations could exceed the $5,000,000 threshold in §453A.
How it works
With a stated maximum, you compute the gross profit percentage using the maximum possible price. Each payment you receive, including the closing payment, is multiplied by that percentage to find the gain for the year. If the earnout ends up smaller than the maximum, the gross profit percentage is recomputed going forward, and any gain reported in excess of the gain actually realized is generally recovered as a loss when the contingency is finally resolved.
Electing out of the installment method does not mean paying tax on the face amount of the earnout. It generally means valuing the contingent right and reporting that value in the year of sale, with later adjustments. That can accelerate tax on money you may never receive, which is why most sellers keep the installment method.
Character is a separate question. If payments stop when you leave the company, scale with your hours, or look like market compensation, the IRS can treat them as wages or other compensation. Compensation is ordinary income, is subject to employment taxes if you are an employee, and is deductible by the buyer. The purchase agreement and any employment agreement should be consistent with the economic reality.
Report installment sales on Form 6252 for each year you receive payments.
Assumptions: Tax year of sale 2026; the seller is married filing jointly, lives in Texas, and sells C corporation stock (no recapture) with a $2,000,000 basis; selling expenses are ignored.; The agreement states a maximum price of $12,000,000; the earnout is paid in a later year.; Gain is taxed at 20% plus the 3.8% net investment income tax (23.8%), because the seller's other income already exceeds the $613,700 top of the 2026 joint 15% band and the $250,000 NIIT threshold; future-year rates are assumed to be the same.; Imputed interest under §483 or §1274 is not computed here; in practice part of the earnout payment would be ordinary interest income.
| Gross profit using the maximum price ($12,000,000 − $2,000,000) | $10,000,000 |
|---|---|
| Gross profit percentage ($10,000,000 ÷ $12,000,000) | 83.33% |
| Year of sale: gain on $8,000,000 received | $6,666,667 |
| Year of sale: tax at 23.8% | $1,586,667 |
| If the full earnout is paid: gain on $4,000,000 | $3,333,333 |
| If the full earnout is paid: tax at 23.8% | $793,333 |
| If no earnout is paid: total gain actually realized ($8,000,000 − $2,000,000) | $6,000,000 |
| If no earnout is paid: excess gain reported in the year of sale | $666,667 |
The installment method taxes each payment as it arrives, but with a stated maximum the seller reports gain early at the maximum-price ratio and generally recovers any excess as a loss if the earnout falls short.

Risks and IRS scrutiny
Common problems include reporting all recapture as installment income, ignoring imputed interest, missing the §453A interest charge, pledging the installment obligation as collateral (which is treated as a payment), and labeling compensation as purchase price. Earnout disputes with the buyer also create tax timing questions that should be documented as they arise.
Who it is not for
The installment method is not available to dealers, to sellers of inventory, or for publicly traded stock or securities. An earnout structure is not for a seller whose 'earnout' is really a retention bonus; substance controls. And it is not a way to change ordinary income into capital gain.

Frequently asked questions
Is an earnout taxed at closing?
Not usually. The installment method under IRC §453 applies automatically, so the earnout is taxed when received. You can elect out, but then the value of the earnout is generally reported in the year of sale.
What if the earnout is never paid?
With a stated maximum price, you reported gain at the maximum-price ratio. If the earnout is not paid, the excess gain reported is generally recovered as a loss when the contingency is finally resolved.
Is any of the earnout interest income?
Possibly. If the agreement does not state adequate interest, §483 or §1274 treats part of each deferred payment as interest, which is ordinary income.
When is an earnout treated as compensation?
When the payments are really for your future services, for example when they depend on your continued employment. Compensation is ordinary income and may be subject to employment taxes.
