What happens to a Section 453 installment note upon the death of the seller?

Upon the death of a seller holding a Section 453 installment note, the remaining deferred gain generally does not trigger immediate recognition for income tax purposes. Instead, the installment note becomes an item of "income in respect of a decedent" (IRD). This means that the inheritors of the note, such as the seller's estate or beneficiaries, continue to report the deferred gain as they receive future payments, just as the original seller would have.

The key characteristic of IRD is that it does not receive a step-up in basis to fair market value at the date of death, unlike most other inherited assets. This means the inheritors recognize the same proportion of gain on each payment as the original seller would have. However, to partially mitigate the double taxation that might occur (estate tax on the value of the note and income tax on the deferred gain), the inheritors may be allowed an income tax deduction for the federal estate tax attributable to the inclusion of the installment note in the decedent's gross estate.

Proper estate planning is crucial to ensure the smooth transfer and continued deferral of the installment note. The seller's will or trust should clearly specify how the installment note is to be distributed. While the income tax liability continues for the inheritors, the deferral mechanism of Section 453 remains intact, allowing for continued spreading of the capital gains tax burden over the life of the note, even after the original seller's passing.
