How is gain calculated when a seller repossesses real property?
Under IRC §1038, taxable gain is generally payments received before repossession minus gain already reported, capped at the original gross profit minus gain already reported minus repossession costs. With $80,000 of gross profit, $20,000 reported and $5,000 of costs, the cap is $55,000.
The tax year after a buyer defaults
Sellers who financed a sale and then had to take the property back are often surprised it has tax consequences. The question comes at filing time, usually from someone who has never dealt with it.

What lands in your inbox
When a client asks your firm to review the result, the request arrives as a contact record with their inputs and results attached, by email and, on paid plans, by webhook to your CRM.
Received
Gross profit, reported gain, payments and costs show the size of the transaction and the client's records. Missing figures suggest a client who needs help reconstructing the installment sale.
The gain and its cap
Gain Before Limit is payments received minus gain reported. Profit Cap (Limit) is gross profit minus gain reported minus repossession costs. Taxable Gain on Repossession is the smaller of the two.
Payments Received confirms the figure used.
Results shown: Taxable Gain on Repossession · Profit Cap (Limit) · Payments Received · Gain Before Limit.
Applying the cap
Gross profit $80,000, gain reported $20,000, repossession costs $5,000: the cap is $80,000 − $20,000 − $5,000 = $55,000. If payments received were $50,000, gain before limit is $30,000, so taxable gain is $30,000.
Why a specialist calculator signals expertise
Few firms handle §1038 repossessions often, so a calculator on the topic positions your firm as the specialist. The clients who need it typically own real estate and have other complex matters.
It's a niche tool best placed on real estate or small-business service pages.

Terms your client sees in the calculator
These definitions appear in the calculator's collapsible Definitions block, so clients don't have to call to ask what a label means.
- Taxable gain on repossession
- The gain a seller reports when taking back real property sold on installment terms. Under IRC §1038, as this calculator applies it, it equals payments received before repossession minus gain already reported, but no more than the profit cap. It is taxed with the same character as the original sale gain.
- Installment sale
- A sale in which at least one payment is received after the tax year of the sale, often with the seller financing the buyer. Instead of reporting the whole gain at once, the seller reports a share of each principal payment as gain. Repossession happens when the buyer defaults and the seller takes the property back.
- IRC §1038
- The section of the Internal Revenue Code that governs repossession of real property the seller had financed. It limits the gain recognized on taking the property back and generally means no loss is deductible and bad-debt deductions are restricted. Repossessions of personal property follow different rules and are not covered by this calculator.
- Gross profit
- The total gain on the original sale: selling price minus the property’s adjusted basis and selling expenses. It is the gain you would have reported over all installment payments if the buyer had paid in full. It is the starting point for the profit cap that limits the taxable gain on repossession.
- Adjusted basis
- Your tax investment in the property: generally the original cost plus capital improvements, minus depreciation claimed and certain other reductions. It is subtracted from the selling price to find the gross profit. A lower adjusted basis, for example after years of depreciation on a rental, means a larger gross profit.
- Gain already reported
- The portion of the installment-sale gain you included in income in earlier tax years, typically from each principal payment received. It is subtracted twice in this calculation: from the payments received, so the same gain is not taxed again, and from the gross profit when setting the cap.
