When a taxpayer sells property at a gain, the tax is generally due in the year of sale. But what if the buyer pays over several years? Requiring the seller to pay tax on the full gain immediately – before receiving all the cash – could be a hardship. Section 453 provides the solution: the installment method, which allows the seller to recognize gain proportionally as payments are received.
The Basic Formula
Under Section 453(c), the gain recognized in any year is:
Gain = (Gross Profit ÷ Contract Price) × Payments received in that year
The ratio (Gross Profit ÷ Contract Price) is the “gross profit percentage.” It remains constant throughout the installment period.
Definitions under Reg. Section 15A.453-1(b):
- Gross profit = Selling price – Adjusted basis (plus certain recapture amounts under Sections 1245 and 1250, which are recognized immediately).
- Contract price = Selling price – (“Qualified indebtedness” assumed by the buyer, but not exceeding the seller’s basis in the property). If the debt assumed exceeds the seller’s basis, the excess is treated as a payment in the year of sale.
Example – Basic Installment Sale
Seller owns land with an adjusted basis of $100,000. He sells it for $300,000, payable $50,000 down and $50,000 per year for five years (total $300,000). The selling price is $300,000, the gross profit is $200,000, and the contract price is $300,000 (no debt assumption). The gross profit percentage is 200,000/300,000 = 66⅔%.
In year one, seller receives $50,000 down. Gain recognized = $50,000 × 66⅔% = $33,333. In each of the next five years, seller receives $50,000 and recognizes $33,333 gain. After five years, all $200,000 gain is recognized.
When Debt Assumption Changes the Calculation
If the buyer assumes a mortgage on the property, the calculation changes. Suppose seller’s adjusted basis is $100,000, but the property is subject to a $80,000 mortgage that the buyer assumes. Selling price is $300,000, payable $50,000 down and $170,000 over time. The “qualified indebtedness” ($80,000) does not exceed the seller’s basis ($100,000), so the contract price is $300,000 – $80,000 = $220,000. Gross profit is still $200,000. Gross profit percentage = 200,000/220,000 = 90.9%. In year one, $50,000 down × 90.9% = $45,450 gain. The mortgage assumption isn’t treated as a payment because it doesn’t exceed basis.
If the mortgage assumed exceeds the seller’s basis – say $120,000 mortgage, basis $100,000 – the excess ($20,000) is treated as a payment in the year of sale. Contract price = Selling price – seller’s basis (not the full mortgage). So contract price = $300,000 – $100,000 = $200,000. Gross profit is still $200,000. Gross profit percentage = 100%. The seller recognizes the entire $200,000 gain over time: the $20,000 excess mortgage is a payment in year one, and each subsequent payment is 100% gain until all $200,000 is recognized. This is the “debt exceeds basis” rule in Reg. Section 15A.453-1(b)(3)(i).
What Qualifies for Installment Treatment?
Section 453(b) defines an “installment sale” as a disposition of property where at least one payment is to be received after the close of the taxable year of disposition. However, the installment method does not apply to:
- Dealer dispositions – regular sales of inventory or property held for sale to customers. Section 453(b)(2)(A). Dealers must use accrual accounting and cannot defer gain.
- Sales of publicly traded stock or securities – Section 453(k)(2)(A). These are too liquid; the seller can sell the securities or borrow against them to pay the tax.
- Sales of property under a revolving credit plan – Section 453(k)(1).
The Election Out
A taxpayer may elect out of the installment method and recognize the full gain in the year of sale. Section 453(d)(1). This may be beneficial if the taxpayer has capital loss carryforwards that would offset the gain, or if the taxpayer expects higher tax rates in future years. The election is made by reporting the full gain on the return for the year of sale.
Second Dispositions by Related Persons
Section 453(e) prevents abuse when a taxpayer sells property to a related person on the installment method, and the related person then sells the property to a third party for cash. Without the rule, the original seller could defer gain while the related person holds the cash.
Example: Father sells land to Son on installment sale, with $100,000 gain. Son immediately sells the land to a third party for cash. Under Section 453(e), the second disposition is treated as a payment to Father, causing immediate recognition of the deferred gain (subject to limits). The “related person” definition incorporates Sections 267(b) and 318(a), including family members.
The rule applies only to dispositions within two years of the first sale. Section 453(e)(2). It does not apply if the second disposition is involuntary (condemnation) or if the taxpayer can show that tax avoidance was not a principal purpose.
Contingent Payment Sales
In Burnet v. Logan, 283 U.S. 404 (1931), the Supreme Court allowed a taxpayer to treat a sale as “open” – recovering basis before recognizing gain – because the selling price was contingent on future production of ore and had no ascertainable fair market value. The Court held that “as annual payments on account of extracted ore come in, they can be readily apportioned first as return of capital and later as profit.”
Regulations under Section 453 now provide specific rules for contingent payments, generally requiring the taxpayer to use one of three methods:
- Stated maximum selling price – treat that maximum as the selling price and compute gross profit percentage.
- Fixed term of payment – allocate basis equally over the payment term.
- Neither maximum nor fixed term – allocate basis over 15 years as a default.
Depreciation Recapture
Sections 1245 and 1250 recapture (ordinary income from prior depreciation) must be recognized in the year of sale, not deferred under the installment method. Section 453(i). The recapture amount reduces the gross profit for purposes of the installment method.
In *Rev. Rul. 2009-13*, the IRS clarified that depreciation recapture is recognized first, and only the remaining gain can be deferred.
Planning Considerations
The installment method is a powerful deferral tool. Sellers can reduce their effective tax rate by spreading gain over multiple years, potentially keeping them in lower brackets. However, the deferral does not affect the character of the gain (e.g., capital gain remains capital gain; it’s just recognized later).
Sellers should also consider the risk of buyer default. The installment method does not accelerate gain if the buyer stops paying; the seller simply recognizes loss (if any) in the year the debt becomes worthless (subject to the rules of Section 166, which may treat the loss as a non-business bad debt – a short-term capital loss – severely limiting its value).
For most taxpayers, the installment method is a valuable option when selling real estate or other non-inventory property. It allows the seller to “pay as they receive” – matching the tax liability with the cash flow from the sale.
