What are the ramifications of an installment sale if the buyer defaults on payments?

Question

Tyler Smith · Accepted Answer

A buyer's default in an **installment sale** can lead to significant tax consequences for the seller, even if only a small amount of cash was initially received. The tax treatment upon default heavily depends on the type of property involved.

## Repossession of Real Property

If the seller repossesses **real property** due to a buyer's default, generally:

*   **No gain or loss is recognized on the repossession itself.** This rule aims to return the seller to a position similar to their original ownership.
*   **Exceptions apply for prior income.** Any cash or other property received before the repossession that was already recognized as income will retain its tax treatment.
*   **Basis Adjustment.** The seller essentially reacquires their original **basis** in the installment obligation, adjusted for any gain previously recognized and any costs incurred during the repossession process.

This approach acknowledges that the seller hasn't truly realized a profit from the repossessed property. For more on the specifics of these sales, see [comparing Section 453 to 1031 Exchange for real estate capital gains](/qa/comparing-section-453-to-1031-exchange-for-real-estate-capital-gains).

## Repossession of Personal Property

When **personal property** is repossessed, the situation differs:

*   **Taxable event.** Repossession of personal property is generally treated as a taxable event.
*   **Gain or loss calculation.** The seller recognizes a gain or loss calculated as the difference between the **fair market value** of the repossessed property and the **basis of the installment obligation** at the time of repossession.
*   **Basis of obligation definition.** The basis of the installment obligation is typically the face value of the note minus any **deferred gross profit** not yet reported.
*   **Cash received after default.** If the seller receives additional cash or other consideration *after* the default but *before* the actual repossession, that amount generally triggers taxable income.
