A buyer's default on an installment note in a Section 453 sale can have significant tax and financial implications for the seller. When a buyer defaults, the seller typically repossesses the property or assets sold. For tax purposes, the repossession itself is a taxable event. The seller must calculate gain or loss on the repossession, which generally equals the difference between the fair market value of the repossessed property at the time of repossession and the seller's basis in the installment obligation (which is the unpaid principal balance minus the unrecognized gain component).

If the repossessed property is the same property originally sold, specific rules under Section 1038 for real property or general tax principles for personal property apply. For real property, any gain recognized on repossession is generally limited to the amount of money and other property received (excluding the installment note itself) before the repossession, less the gain previously reported. Any loss on repossession is also deductible. Importantly, the character of the gain or loss on repossession usually matches the character of the gain from the original sale. The seller's basis in the reacquired property becomes its fair market value at the time of repossession. It is crucial for sellers to include robust security agreements and legal protections in the original sale agreement to facilitate repossession and mitigate financial losses, while also understanding the immediate tax consequences of such an event.
