Installment Sales (IRC §453): Spreading Gain Over Time, Form 6252 and the Rules That Limit Deferral
In Short
An Installment Sale under IRC §453 is a sale of property where at least one payment is received after the tax year of the sale, so the seller reports the gain as payments come in. It is commonly used by people selling a business, real estate or other property with seller financing.
TL;DR
- Gain is reported each year in proportion to the payments received, using a gross profit percentage, on Form 6252 [1][2].
- Depreciation recapture is taxed in the year of sale, even if no payment is received that year [1][2].
- Sales of inventory, dealer sales and publicly traded stock or securities cannot use the installment method [1][2].
- Special rules apply to sales to related persons, and interest is charged on deferred tax for large sales [2][3].
- From tax years beginning after July 4, 2025, sellers of qualified farmland to qualified farmers can elect to pay the tax in four annual installments [4][5].
Quick Facts
| Legal Reference | IRC §453, §453A |
|---|---|
| Complexity | Medium |
| Audit Risk | Low |
| Setup Cost | Moderate — a written note, security agreement and legal review |
| Time to Implement | Negotiated as part of the sale contract |
| Illustrative Example | Illustrative example, not a projection. An owner sells a parcel of investment land with a $400,000 basis for $1 million: $200,000 down and the rest in payments over eight years with interest. The gross profit percentage is 60%, so $120,000 of the down payment is reported as gain in the year of sale and 60% of each later principal payment as it arrives. Land is not depreciated, so there is no recapture in this example. Actual results depend on the facts and tax rates. |

What Is an Installment Sale?
An installment sale is a sale of property where the seller receives at least one payment after the close of the tax year in which the sale occurs [1][2]. Under the installment method, the seller reports the gain over time: the income recognized each year is the share of that year's payments that the gross profit bears to the total contract price [2]. Losses cannot be reported on the installment method.
The method applies automatically to qualifying sales unless the seller elects out by the due date of the return for the year of sale, in which case the entire gain is reported in that year [1][2]. Each payment usually has three parts: interest income, a tax-free return of basis and gain [1]. If the contract does not state adequate interest, part of the principal may be recharacterized as interest [1].
Several rules limit deferral. The installment method does not apply to dealers, to regular sales of inventory, or to sales of stock or securities traded on an established market [1][2]. Depreciation recapture under §1245 or §1250 is taxed in the year of sale [1][2]. Sales of depreciable property to certain related persons generally cannot use the method, and a related buyer's resale within two years can accelerate the seller's gain [1][2]. For larger sales, §453A adds an interest charge on the deferred tax and treats loans secured by the installment note as payments [3].
How Does an Installment Sale Work?
- The buyer and seller agree on a down payment, a promissory note with a stated interest rate and a payment schedule, often secured by the property [1].
- In the year of sale, the seller figures the gross profit percentage and reports any depreciation recapture in full on Form 4797 and Form 6252 [1][6].
- Each year a payment is received, the seller reports interest as ordinary income and the gain portion of principal on Form 6252 [1].
- If the face amount of installment obligations from sales over $150,000 that are outstanding at year end exceeds $5,000,000, the seller pays an interest charge on the deferred tax [3].
- If the seller pledges the note as security for a loan on a sale over $150,000, the net loan proceeds are treated as a payment on the note [1][3].
The Good: What Are the Benefits of an Installment Sale?
The Bad: What Are the Drawbacks of an Installment Sale?
- Depreciation recapture is taxed in the year of sale, even if little cash is received that year [1][2].
- Not available for inventory, dealer sales or publicly traded stock and securities [1][2].
- Large sellers may owe an interest charge on the deferred tax under §453A [3].
- Tax rates can change during the payment period, for better or worse.
The Ugly: What Are the Serious Risks of an Installment Sale?
- If the buyer defaults, the seller may have to repossess the property and deal with the tax consequences, after already paying tax on part of the gain [1].
- Sales of depreciable property to related persons generally lose the installment method, and all payments are treated as received in the year of sale [1][2].
- Promoters market “monetized installment sales,” in which an intermediary buys the property and the seller receives loan proceeds equal to the price; the IRS has proposed regulations to identify these as listed transactions, requiring disclosure and carrying penalties [7].

Frequently Asked Questions
How Is an Installment Sale Taxed?
Each payment is split into interest, return of basis and gain. The gain portion equals the principal received times the gross profit percentage — gross profit divided by the contract price — and is reported on Form 6252 [1][2]. Interest is ordinary income [1].
Is Depreciation Recapture Deferred in an Installment Sale?
No. Depreciation recapture income is reported in the year of sale, whether or not a payment is received that year [1][2]. Only gain above the recapture amount is eligible for installment reporting.
Can I Use an Installment Sale to Sell to a Family Member?
Yes, with limits. If a related buyer resells the property within two years, the seller may have to report gain as if the payments were received [1][2]. Sales of depreciable property to certain related persons generally cannot use the installment method at all [1][2].
What Is Interest on Deferred Tax Under Section 453A?
For obligations from sales over $150,000, if the face amount of those obligations outstanding at year end exceeds $5,000,000, the seller pays interest on part of the deferred tax at the IRS underpayment rate [3]. Personal-use property and farm property are excepted [3].
