If a seller passes away while still holding an installment note, the deferred gain from the original sale does not typically accelerate and become immediately taxable on the decedent's final income tax return. Instead, under Section 453B(c) and related provisions, the installment note is considered an "income in respect of a decedent" (IRD) asset. This means that the deferred gain maintains its character and is passed to the decedent's estate or beneficiaries who inherit the note. The estate or beneficiaries then recognize the remaining deferred capital gain as they receive the installment payments, in the same manner and proportion as the original seller would have. There is no step-up in basis for the installment note itself *for income tax purposes* at death; rather, the heirs receive the same income tax basis the decedent had for the note. This prevents the untaxed gain from escaping taxation entirely. However, the fair market value of the installment note at the time of death *is* included in the decedent's gross estate for estate tax purposes. If estate taxes are paid on the fair market value of the note, the heirs may be eligible for an income tax deduction for the estate tax attributable to the IRD (known as the Section 691(c) deduction), which can help mitigate the double taxation of the value. Proper estate planning and communication with beneficiaries are crucial to ensure they understand their tax obligations related to receiving and collecting on an inherited installment note.
