What Happens to an Installment Note When the Seller Dies

By Hans Goldstein · Updated 2026-09-27

When the seller of an installment note dies, the note passes to the estate or heirs and the payments keep coming, but the tax does not disappear. The unpaid gain is income in respect of a decedent (IRD): there is no step-up in basis on the note, and whoever receives it reports the gain as each payment arrives, exactly as the seller would have (§§691(a)(4), 1014(c)). Property held until death, by contrast, gets a new basis equal to its value at death, and its built-in gain is never taxed.

That difference is one of the most important estate questions for any seller over 60 thinking about a note.

The note passes to heirs; the tax does not disappear

Four rules do the work:

So the same gross profit percentage, the same character (unrecaptured §1250 gain first, then long-term capital gain), and ordinary interest income all carry over to the heirs.

Two exceptions that do trigger tax. If the note is canceled, becomes unenforceable, or is transferred to the buyer because of the holder's death, that is a disposition, and the estate must figure its gain. If the holder and buyer were related, the note's value is treated as no less than its full face amount (Pub. 537; §691(a)(5)). That is the self-canceling note problem, covered below.

Heirs keep reporting the gain as payments arrive

Each year a payment comes in, the heir (or the estate, until the note is distributed) reports:

Worked example: seller dies after year three

Simple example. A seller sells a rental for $1,500,000. Her installment sale basis is $500,000, so gross profit is $1,000,000 and the gross profit percentage is 66.67%. She takes $300,000 down and carries a $1,200,000 note, $120,000 of principal a year for ten years, plus interest. No recapture, for simplicity.

She receives the down payment and three annual payments, then dies.

Amount
Principal she received (down payment + 3 x $120,000) $660,000
Gain she reported during life ($660,000 x 66.67%) $440,000
Principal still owed at death $840,000
Gain still inside the note (IRD) ($840,000 x 66.67%) $560,000
Step-up on the note at death None
Gain her children report over the next seven years $560,000, about $80,000 a year

Now compare two ways her family could have ended up:

Same seller, simple example Heirs receive Built-in gain the heirs will pay tax on
Sold on the note, died after year 3 $840,000 of remaining note payments $560,000
Kept the rental, died holding it (worth $1,500,000 at death) A building with a $1,500,000 basis $0 (erased by the §1014 step-up)

The note also cannot be undone. Once the sale closes, the family is on the IRD path.

The §691(c) deduction for estate tax paid

If the note was included in a taxable estate and federal estate tax was paid on it, the heir who reports the IRD gets an itemized deduction for the estate tax attributable to it (§691(c)). That softens the double hit of estate tax and income tax on the same dollars.

In practice, most families will not use it. The 2026 basic exclusion is $15,000,000 per person (§2010(c)(3)), so most estates owe no federal estate tax, and with no estate tax there is no §691(c) deduction. The IRD income tax still applies.

Cancelling the note at death (SCIN)

A self-canceling installment note is written to cancel automatically when the seller dies. It is a family estate-planning tool: the unpaid balance is meant to leave the estate. Three cautions:

A SCIN belongs with an estate attorney who drafts them regularly, not in an ordinary sale.

Structured sale payments after death (beneficiary)

In a structured installment sale, the buyer pays in full at closing and an assignment company takes on the obligation to pay the seller, usually funded by a fixed annuity it owns (some programs use a funding agreement instead). The seller is an unsecured creditor of the assignment company, the schedule is locked, and a commission is built into the pricing. No IRS ruling specifically approves the assignment structure; it relies on the general installment rules. See the structured installment sale guide.

At death:

A seller-financed note has the same tax result at death, plus one more variable: whether the buyer keeps paying your heirs.

Compare: holding the property until death (step-up)

For some older owners, the better estate result is to not sell at all:

The book's chapter on the "swap till you drop" plan runs this comparison with numbers: 1031, borrow and hold vs an installment sale. The short version: the step-up does the heavy lifting, and the older and less healthy the owner, the more it is worth.

Run a note in the installment sale calculator to see how much gain would still be inside it at each year, then read the complete installment sale guide.

Bottom line

An installment note outlives its seller, but so does the tax. The heirs get the payments and the IRD, with no step-up. A self-canceling note does not escape the income tax, and a structured sale's payments go to the beneficiary on schedule but cannot be cashed out. If holding the property until death is a realistic plan, compare it against the sale before you sign, because the step-up is the one benefit a note can never get back.
