In a Section 453 installment sale, both the seller and the buyer have distinct, yet interconnected, reporting responsibilities to the IRS. For the seller, the primary reporting mechanism is Form 6252, Installment Sale Income. This form is used to report the gross profit from the sale, the contract price, and to calculate the gross profit percentage. Each year that installment payments are received, the seller must report the portion of that payment that constitutes taxable gain using this form. This ensures that the capital gains tax is deferred and recognized proportionally over the payment period. If the sale involves depreciable property, additional rules under Section 453(g) might apply, particularly if the buyer is a related party, which could limit installment reporting. Furthermore, if interest is charged on the installment note, the seller must report this as ordinary income.

For the buyer, the reporting requirements are generally less complex from a capital gains perspective, as they are not recognizing gain on the sale. However, if the sale involves real property or a business, the buyer may have obligations to report interest paid to the seller (e.g., on Form 1098, Mortgage Interest Statement, if applicable). More critically, the buyer's basis in the acquired asset is its cost, typically the sum of all installment payments. The buyer will use this basis for future depreciation deductions, if applicable, or when they eventually sell the asset. Both parties must also be mindful of Section 483 and 1274, which may impute interest if the stated interest rate is too low or nonexistent, impacting both parties' taxable income and deductions. Accurate record-keeping and annual reporting are crucial for both parties to remain compliant and avoid penalties.
