Escrows and basis at closing: when held-back proceeds become income

A 5–15% indemnity escrow is standard closing furniture, and its tax treatment follows a default most sellers would choose anyway: escrowed amounts genuinely at risk are not income at closing, and each release is taxed as an installment payment in the year received, part gain and part imputed interest. The exceptions — constructive receipt, elections out of Section 453, and the yearly tax on escrow earnings — are where returns get filed wrong.

Year of sale or year of release?

The controlling question is constructive receipt: an amount is income when the seller's right to it is not subject to substantial limitations. An escrow securing indemnity obligations, held by an independent agent, with the buyer's bona fide right to claim against it, is substantially limited — so under Section 453 the seller includes escrow amounts in the installment computation as payments only when released. Contrast an escrow that exists solely to bridge a timing formality, where no claims can realistically reach it: the IRS treats that as received at closing. The gross profit ratio is computed treating the escrow as part of the total contract price; if claims later reduce what is released, the contingent-price rules of Treas. Reg. §15A.453-1(c) (see eCFR Title 26) recompute so the seller is not taxed on money never received.

A seller who elects out of installment treatment reports the full price — escrow included, at fair value — in the sale year. Sellers do this to absorb expiring losses, to fix the Section 1202 exclusion in one year, or to escape the Section 453A interest charge on large deferrals; the tradeoffs mirror those in installment sales in business exits. Electing out and also deferring the escrow is not on the menu.

Illustrative treatment of a $1.5 million escrow released 18 months after closing (no claims, 4% AFR, 80% gross profit ratio):

Interest, actual and imputed

Two interest streams run in parallel. The escrow account's actual earnings are taxed annually to whichever party owns them under the escrow agreement — customarily the seller, even though the cash sits with the agent. And because the release is a deferred payment on a sale, Sections 483/1274 impute interest at the applicable federal rate from closing to release unless the agreement states adequate interest; that slice is ordinary income ineligible for capital rates or the QSBS exclusion — a drafting point flagged in QSBS exit planning. Escrow agreements should say explicitly who reports the account earnings and whether releases carry stated interest; silence produces 1099s that match nobody's return.

Claims, basis, and the paper trail

When the buyer collects an indemnity claim from escrow, the payment is in substance a reduction of purchase price: the seller's total contract price drops (with installment-method recomputation or, if gain was already fully reported, a capital loss under the Arrowsmith doctrine keyed to the original sale's character), and the buyer reduces basis in the acquired stock or assets rather than recognizing income. In asset deals both parties file supplemental Form 8594 reflecting the adjusted price — typically against Class VII goodwill, consistent with the original allocation schedule. Indemnity payments for items the buyer deducted, or that compensate for lost profits rather than impaired value, can instead be income — the agreement should characterize payments and the parties should report accordingly.
