What are the implications of a seller passing away during an active Section 453 installment sale?

Question

Tyler Smith · Accepted Answer

The passing of a seller during an active **Section 453 installment sale** has specific tax implications, primarily centered on how the deferred gain is treated.

## Income in Respect of a Decedent (IRD)

The installment obligation generally becomes an "**item of income in respect of a decedent**" (**IRD**) for the estate or the beneficiaries who inherit the right to receive the remaining payments. This means:

*   The deferred capital gains tax liability continues to be deferred.
*   The estate or heirs will recognize the remaining gain as payments are received.
*   The character of the gain (e.g., capital gain) remains the same as it would have been for the original seller.

This anti-acceleration provision prevents a "**step-up in basis**" for the installment note itself upon the seller's death, which would otherwise eliminate the built-in gain. The portion of the note's value attributable to the unrecognized gain will generate taxable income for the recipients as payments are collected.

## Estate Tax Deduction

A significant benefit for the recipients of an installment note that is IRD is a **deduction for the estate tax** attributable to the inclusion of the net value of the installment obligation in the decedent's gross estate. This deduction helps to mitigate the impact of double taxation, where the asset is subject to estate tax and subsequently income tax on the IRD.
