This AIM Financial tax-form guide covers IRS Form 6252: Installment Sale Income. This form is generally used when you sell qualifying property and receive at least one payment after the end of the tax year in which the sale occurs. Instead of recognizing all eligible gain at once, you may be able to report the taxable gain over the years you receive payments. Special rules apply, including for depreciation recapture and certain related-party transactions.

Selling a business, investment property, or other qualifying asset can create a significant tax bill. But what happens when the buyer does not pay the entire purchase price upfront? If you receive payments over several years, you may be eligible to use the installment method to report the taxable gain over time.

IRS Form 6252, Installment Sale Income, helps taxpayers calculate and report qualifying installment-sale income. Understanding how this form works is important for individuals, business owners, investors, and property sellers who want to report their transactions accurately.

AIM Financial helps taxpayers in Grand Rapids, Kentwood, Wyoming, and throughout West Michigan understand tax reporting requirements and prepare their federal income tax returns.

What Is IRS Form 6252?

IRS Form 6252 is used to report income from a qualifying installment sale. Generally, an installment sale occurs when you sell property and receive at least one payment after the end of the tax year in which the sale takes place.

Under the installment method, you generally report the eligible gain as payments are received rather than reporting the entire gain in the year of sale. This can spread taxable gain over multiple tax years when the transaction qualifies. <Cite refs={[“turn385116search0″,”turn385116search1”]}/>

Common examples include:

• Selling qualifying real estate with the buyer making payments over several years.
• Selling certain investment property under a seller-financed agreement.
• Selling a business or qualifying business assets through a payment plan.
• Receiving installment payments under a contract rather than receiving the full purchase price at closing.

Not every sale qualifies. The property type, payment terms, and other circumstances determine whether the installment method is available.

How Does an Installment Sale Work?

Imagine you sell qualifying investment property for $100,000. Your adjusted tax basis is $60,000, and you have no selling expenses or other adjustments for this simplified example.

Your total gain is $40,000.

If the transaction qualifies for installment reporting and the gross profit percentage is 40%, then 40% of each qualifying principal payment generally represents gain, while the remaining portion represents recovery of your tax basis. Interest is reported separately.

For example, if you receive a $20,000 principal payment, the gain portion would generally be $8,000 under these simplified assumptions.

The remaining $12,000 would generally represent a return of your adjusted basis. This example assumes no special rules, depreciation recapture, debt-related adjustments, or other complications.

The actual calculation can be more complex when the buyer assumes a mortgage, the property was depreciated, or the agreement includes interest or other forms of payment. <Cite refs={[“turn385116search1″,”turn385116search3”]}/>

What Is the Gross Profit Percentage?

The gross profit percentage is a key part of Form 6252. It generally measures the portion of the contract price that represents gain rather than recovery of your investment.

To calculate it, taxpayers generally need to determine:

• The selling price of the property.
• The property’s adjusted tax basis.
• Qualifying selling expenses.
• Any applicable depreciation recapture.
• The contract price and any relevant liabilities or other payment adjustments.

The gross profit percentage is then used to determine how much of eligible installment payments is reported as gain.

Because mortgages, assumed liabilities, and depreciation can affect the calculation, sellers should not simply divide their expected profit by the original selling price without reviewing the IRS rules.

How Do You Complete Form 6252?

Form 6252 contains sections for calculating gross profit and reporting installment-sale income.

Part I: Gross Profit and Contract Price

This section generally establishes the property’s selling price, adjusted basis, gross profit, and contract price. It helps determine how much of the sale represents gain and how payments will be treated.

Part II: Installment Sale Income

This section calculates the gain reported for the tax year. It considers the gross profit percentage, payments received during the year, and payments reported in previous years. The gain may need to be reported on Schedule D or Form 4797, depending on the type of property and the character of the gain.

Part III: Related-Party Sales

Special reporting may apply when property is sold to a related person. Additional rules can accelerate recognition of deferred gain if the related buyer disposes of the property before completing payments.

The applicable lines and calculations depend on the transaction. Taxpayers should follow the instructions for the relevant tax year and retain a copy of the installment-sale calculations for future returns. <Cite refs={[“turn385116search27″,”turn385116search1”]}/>

Is Interest Taxable on an Installment Sale?

Yes. Interest received from an installment sale is generally taxable as ordinary income and is reported separately from the gain calculated on Form 6252.

A seller-financed agreement should clearly address interest. If the contract charges little or no interest, federal tax rules may treat part of the payments as unstated interest or original issue discount.

This can affect the amount treated as interest rather than principal, even when the parties did not specifically label that portion of the payment as interest. <Cite refs={[“turn385116search1″,”turn385116search3”]}/>

For this reason, it is important to review the sales contract and payment schedule before preparing the tax return.

When Can You Not Use the Installment Method?

The installment method has important limitations.

• Sales that produce a loss: You cannot use the installment method to report a loss. The loss generally must be reported in the year of sale under the applicable rules.
• Inventory and certain dealer sales: Sales of inventory and many sales of property held for sale to customers in the ordinary course of business generally do not qualify.
• Market-traded stocks and securities: Special rules generally prevent installment reporting for sales of stock or securities traded on an established securities market.
• Depreciation recapture: Certain depreciation recapture must be recognized in the year of sale, even if the buyer pays over time.
• Related-party transactions: Additional restrictions may apply, particularly when depreciable property is sold to a related person.

Eligible sellers can also choose to elect out of the installment method and report the sale under the applicable rules for the year of sale. That decision should be considered carefully because it can affect when the gain is taxable. <Cite refs={[“turn385116search1″,”turn385116search27”]}/>

Do You File Form 6252 Every Year?

Generally, Form 6252 must be filed for the year of the sale and each subsequent year of the installment agreement through the year the final payment is received or the installment obligation is otherwise disposed of.

The form may be required even in a year when you receive no payment. Additional reporting applies to certain related-party transactions. <Cite refs={[“turn385116search27″,”turn385116search4”]}/>

Keep copies of the original sales agreement, payment records, interest calculations, closing documents, adjusted-basis records, and prior-year tax returns. These documents help ensure that the correct amount of gain is reported each year.
