Article 59: Installment Sale Structures — Deferring Capital Gains Through Seller Financing

SECTION: Seller Operator Playbook JURISDICTION: New York State / New York City AUDIENCE: Seller, Listing Agent, Brokerage Operator

Executive Thesis

An installment sale under IRC §453 allows a seller to recognize capital gain proportionally as payments are received, rather than recognizing the entire gain in the year of sale. For sellers facing large capital gains on appreciated New York property — particularly those who do not qualify for the IRC §121 exclusion and are not executing a 1031 exchange — installment sales can reduce the effective tax rate by spreading income recognition across multiple years, potentially keeping income below higher bracket thresholds.

Operational Framework: Installment Sale Mechanics

In an installment sale, the seller receives the purchase price over time — typically a down payment at closing followed by periodic payments over a term of years, secured by a purchase money mortgage on the property. Each payment is divided into three components: return of basis (non-taxable), capital gain (taxed at applicable rates), and interest income (taxed as ordinary income).

Gross profit ratio: The percentage of each principal payment that constitutes taxable gain. Calculated as: total gain ÷ contract price. If a seller has a $400,000 gain on a $1,000,000 sale, the gross profit ratio is 40%. For every $100,000 in principal received, $40,000 is taxable gain.

Interest requirement: The seller must charge at least the Applicable Federal Rate (AFR) on the installment note. Below-market interest triggers imputed interest rules under IRC §7872, which recharacterize a portion of principal as interest.

Risk Factor: Counterparty and Structural Risks

Default risk: The seller is extending credit to the buyer, secured by the property. If the buyer defaults, the seller must foreclose — a costly and time-consuming process in New York (judicial foreclosure state, average 12–18 months). The seller's recourse is limited to the property's value at the time of foreclosure.

Depreciation recapture: Under IRC §453(i), depreciation recapture (IRC §1250 gain) must be recognized in full in the year of sale, regardless of whether payments are received. This means investment property sellers cannot use installment reporting to defer the recapture portion of the gain.

Related party rules: Installment sales between related parties are subject to additional restrictions under IRC §453(e) and (f). If the related buyer resells the property within two years, the original seller's deferred gain is accelerated.

Installment sale interest charge: For large installment obligations (face amount exceeding $5 million), an interest charge applies to the deferred tax under IRC §453A. This partially offsets the benefit of deferral for very large transactions.

Decision Framework

Installment sales are most effective for sellers who: (1) are selling investment property with large gains, (2) do not qualify for §121, (3) are not executing a 1031 exchange, (4) have confidence in the buyer's creditworthiness, (5) are willing to accept the risk of holding a purchase money mortgage, and (6) have gains below the $5 million threshold where the installment interest charge applies.
