Escrow and Holdback After a Startup Sale: When Is It Taxed?

Is escrow or holdback money taxed in the sale year or when it is released?

When you sell private startup shares at a gain and part of the price is paid in a later year, the sale is an installment sale. Gain on the deferred part is reported in the year you receive it, unless you elect out (26 U.S.C. 453; Publication 537). Each dollar you receive carries the same share of gain, so basis is recovered across the closing payment and the release.

Whether held-back money counts as paid at closing depends on how it is held:

The installment method is not available for stock traded on an established securities market (section 453(k)). A buyer obligation secured by cash or a cash equivalent is treated as a payment (26 CFR 15a.453-1(b)(3)). Publication 537 says an escrow still allows installment reporting when it imposes a substantial restriction serving a real purpose of the buyer.

What makes a case not simple. Escrow treatment turns on the merger agreement's terms: who controls the money, who is taxed on its earnings, and how likely claims are. The Code says escrow accounts are subject to current income tax and leaves the method to regulations (section 468B(g)). Rules for escrows that cover contingencies at closing were proposed but left out of the 2006 final regulations and reserved, so no final rule says who reports those earnings. Follow the agreement's tax clause and the paying agent's reporting, and report consistently with the buyer.

What to gather: the merger agreement and its tax clause, the escrow agreement, the funds flow statement, release and claim notices, every Form 1099-B or other statement you received, and your basis records for the shares sold.

Can I elect out of the installment method?

Yes. To elect out, report the full sale on Form 8949 instead of Form 6252 by the sale-year return due date, including extensions (Publication 537). If you filed on time without electing, you can still elect on an amended return filed within six months of the original due date, excluding extensions, marked "Filed pursuant to section 301.9100-2". Revoking the election needs IRS consent, which is refused when a purpose is avoiding tax or when the year of any payment has closed (26 CFR 15a.453-1(d)).

Electing out puts all the gain in the closing year. For a cash-method individual, the escrowed amount is then valued at no less than the value of the shares sold minus the other consideration, even if claims may reduce it. The election is effectively hard to undo, so compare both years' rates, capital losses, state residence and QSBS before choosing.

How do I report the sale in the closing year on Form 6252?

File a separate Form 6252 for the sale in the closing year and in every later year of the agreement, including the year of the final release. The gain from Form 6252 goes to Schedule D, not Form 8949 (Schedule D instructions).

A sale whose total price cannot be determined by the end of the sale year is a contingent payment sale under 26 CFR 15a.453-1(c). Whether an indemnity escrow makes the price contingent depends on the claim terms; follow the Form 6252 instructions for line 4 and line 5.

Why doesn't my Form 1099-B match the deal price?

The paying agent or broker reports proceeds under its own information-reporting rules, so the form may show the full deal price in the closing year, only the cash paid at closing, or a separate form when the escrow is released. None of these changes the year the gain is taxed. The IRS compares information returns with your return, and a mismatch can produce a CP2000 notice.

For a sale reported on Form 8949, its instructions give codes for a wrong basis (B), a wrong short- or long-term box (T) and unreported selling expenses (E). They give no code for proceeds held in escrow, and no IRS instruction spells out how to tie a full-price Form 1099-B to Form 6252. Ask the issuer whether the amount is right and request a corrected form if it is not. Keep a written reconciliation from the funds flow that ties the form to Form 6252 lines 5 and 21. Getting this wrong can report the escrow twice, or in the wrong year.

What if part of the escrow goes to the buyer for a claim?

Money the buyer keeps for a claim is never received, so it is not gain. Under the installment method, when the maximum price is reduced, the gross profit percentage is recomputed for payments received in and after the year of the reduction (26 CFR 15a.453-1(c)(2)). Earlier years are not changed. If what remains is less than your unrecovered basis, the regulation's examples allow the shortfall as a loss, taken when the rules for worthless debts allow it.

If you elected out and reported the full price at closing, a later claim reduces what you actually receive. How and when that shortfall is claimed depends on the facts, so have it reviewed before filing the release-year return.

Is part of a late release treated as interest?

Possibly. When a sale contract has a payment due more than one year after the sale and not enough stated interest, section 483 treats part of each payment due more than six months after the sale as interest. When the deferred part is the buyer's own debt, such as a fixed holdback, and total payments exceed $250,000, the original issue discount rules of section 1274 generally apply instead. Interest is ordinary income, and it is left out of the selling price and payments on Form 6252 (Publication 537).

For a payment that depends on claims, the interest part is figured when the payment is made, by discounting it back to the sale date at a test rate based on the applicable federal rate (26 CFR 1.483-4). An escrow released within one year, with no later payments, generally has no section 483 interest. Whether earnings paid out of the escrow count as stated interest under the contract is not settled; see the earnings point above.

How does QSBS apply to amounts released later?

If the shares are qualified small business stock, the exclusion follows the gain into each year. The Schedule D instructions say the year's exclusion is the total exclusion times the share of eligible gain recognized that year. Report it on Form 8949 Part II with code Q.

The per-company cap is applied each tax year: the greater of the dollar cap ($10,000,000 or $15,000,000, depending on when the stock was issued) less eligible gain taken into account in earlier years, or 10 times the basis of the stock sold that year (26 U.S.C. 1202(b)). How the basis test works when the gain arrives in a year with no new sale is not spelled out. Whether the shares qualify is covered in QSBS for founders and early employees.

Which state taxes the release if I moved after closing?

It depends on the state you left. California generally sources installment gain on stock and other intangible property to your state of residence when you sold. California still taxes release-year gain from a sale made while you lived there, even after you move away (FTB Publication 1100). The interest part follows your residence when you receive it. California also taxes releases received after you move there, even for a sale made while you lived elsewhere.

Other states set their own sourcing rules, so check the state you left and the state you live in at release. For planning a move around the sale, see moving to another state before selling startup shares.

Is there an extra interest charge on large deferred sales?

Yes, for large deferrals. Section 453A adds interest on the deferred tax when a sale's price is over $150,000 and the face amount of installment obligations that arose during the year and are still outstanding at year-end exceeds $5,000,000. Only the part over that threshold is charged. The charge continues each year the obligation stays outstanding.

The interest equals the unrecognized gain times your top tax rate for that kind of gain (ordinary or long-term capital gain), times the share of obligations over the threshold, times the IRS underpayment rate. It is not figured on Form 6252; Publication 537 shows the steps, and it is reported on Schedule 2 (Form 1040).

Which year's estimated tax covers the release?

Under the installment method, the release is income of the year you receive it, so it is covered by that year's estimated tax or withholding (Publication 505). The closing year has its own payments for the closing gain.

To avoid the underpayment penalty, pay at least 90% of the current year's tax or 100% of the prior year's tax. The prior-year figure rises to 110% when prior-year adjusted gross income was over $150,000 ($75,000 if married filing separately). After a large closing year, the prior-year route for the release year can be costly, because it is based on the closing year's tax. The annualized income installment method in Publication 505 can match payments to a release late in the year. For when the closing tax is due, see taxes when your startup is acquired.

Example

All figures are illustrative, in US dollars, and ignore interest and state tax.

Ten percent in escrow

A founder sells shares with a basis of $200,000 for $3,000,000. The buyer pays $2,700,000 at closing and puts $300,000 in an indemnity escrow for 18 months. Gross profit is $2,800,000, so each dollar received carries 93.33% gain.

• Closing year: $2,700,000 received; gain of about $2,520,000.
• Release year: $300,000 received; gain of about $280,000.
• Total: $2,800,000. Because the release comes more than a year after closing, part of it may be interest instead of gain.

A claim against the escrow

Same sale, but the buyer keeps $50,000 for a claim and releases $250,000. The closing year stays at $2,520,000. In the release year the price drops to $2,950,000 and gross profit to $2,750,000. The remaining $230,000 of gain is reported on the $250,000 received, so total gain is $2,750,000.

A Form 1099-B that doesn't match

The paying agent's Form 1099-B shows $3,000,000 of proceeds in the closing year. The founder's Form 6252 shows $3,000,000 on line 5, $2,700,000 on line 21 and $2,520,000 of gain on line 24. A reconciliation from the funds flow explains the $300,000 still in escrow. In the release year, a new Form 6252 reports the $300,000 received.

Different for you?

• Part of the price depends on future results or on you staying on: see earnout payments after a startup sale.
• You received buyer stock or want the tax on the closing cash: see taxes when your startup is acquired.
• You moved, or plan to move, between closing and release: see moving to another state before selling startup shares and get individual tax help.
• Part of the escrow is for cashed-out stock options: that part is generally pay, not sale price; see taxes when your startup is acquired.
• You are counting on QSBS: check qualification in QSBS for founders and early employees.
• You sold a small owner-run business paid over time: see selling your business.
• Your Form 1099-B doesn't match, a claim was paid from escrow, or you are deciding whether to elect out: these choose the year and amount of gain and are hard to undo; get individual tax help.
