How does Section 453 handle deferred gain when the seller of an installment note dies and the note is inherited by their heirs?

A significant benefit of Section 453 installment sales for estate planning is the treatment of deferred gain upon the seller's death. When the seller of an installment note dies, the deferred gain does *not* accelerate and become immediately taxable at the time of death. Instead, the installment note, including the right to receive future payments, is transferred to the seller's estate or heirs. The income in respect of a decedent (IRD) rules apply to the inherited installment obligation.

This means that the deferred gain maintains its character (e.g., long-term capital gain) and is recognized by the estate or heirs gradually as they receive the remaining installment payments. The person who inherits the note simply steps into the shoes of the original seller for tax purposes. There is no step-up in basis for the income portion of the inherited installment note, unlike most other inherited assets. The portion of each payment representing the original seller's basis is received tax-free, while the portion representing profit (gain) remains taxable to the recipient.

This aspect makes installment sales an attractive estate planning tool, as it avoids a large tax bill at death and can provide a continued stream of income to beneficiaries while deferring the tax liability over time. However, the estate or heirs will need to carefully track the basis and gain components of each payment received. Proper legal and accounting guidance is necessary to ensure correct reporting and compliance for the decedent's final return and the subsequent treatment by the estate or beneficiaries.
