The death of a seller during an active Section 453 installment sale has specific and important tax implications for the seller's estate and beneficiaries. Generally, the deferred gain from the installment obligation does not accelerate upon the seller's death. Instead, the installment obligation becomes an asset of the decedent's estate. The remaining installment payments received by the estate or beneficiaries are considered income in respect of a decedent, or IRD.

This means that the deferred gain continues to be recognized as payments are received, similar to how the seller would have recognized it. The estate or beneficiaries will report the income on their tax returns when received, using the same gross profit percentage that applied to the original seller. A key benefit for the estate is that the installment obligation receives a step-up in basis for estate tax purposes, but only for the principal amount of the note, not for the built-in gain component. However, the IRD aspect means that while the value of the installment obligation is included in the decedent's gross estate for estate tax purposes, the income tax liability on the deferred gain is not eliminated. Beneficiaries receiving IRD may be entitled to an income tax deduction for the portion of the federal estate tax paid attributable to the IRD, preventing double taxation. Careful estate planning is critical when entering into a Section 453 sale, particularly for elderly sellers or those with health concerns, to ensure smooth transition and optimal tax outcomes for heirs.
