Self-Cancelling Installment Note (SCIN): How It Works and Risks
A self-cancelling installment note (SCIN) is a promissory note that cancels any unpaid balance if the seller dies before it is paid off. You sell an asset, usually to a child or other family member, for payments over a term, and if you die early, the buyer owes nothing more. The cancelled balance is generally kept out of your estate, but the buyer must pay a premium for that feature, and the deferred income tax on your gain does not disappear. Your estate pays it.
This page covers how a SCIN is built, what happens at death for estate and income tax, a labeled simple example, and the IRS positions to know. For the ordinary rules at death, see installment notes at death.
How a SCIN works
A SCIN is an ordinary installment sale with one extra clause:
- You sell property to a buyer, typically a family member, at fair market value.
- The buyer signs a note payable over a fixed term, not longer than your life expectancy.
- The note states that if you die before the final payment, the remaining balance is cancelled.
- Because the buyer may pay less than the full price, the note carries a risk premium: either a higher principal amount or a higher interest rate than a plain note.
While you are alive, the payments are reported like any other installment sale. Each principal payment carries gain at your gross profit percentage, and interest is ordinary income. The special treatment kicks in only at death.
Estate tax: why the balance can stay out of your estate
In Estate of Moss v. Commissioner, 74 T.C. 1239 (1980), the Tax Court held that a note which by its own terms cancels at the holder's death has no value to include in the holder's gross estate. The cancellation is part of the bargain the seller made while alive, not a transfer at death.
That result depends on the sale being a bona fide sale for full value. If the price or interest does not reflect the cancellation risk, the shortfall looks like a gift, and the arrangement can be attacked as a disguised transfer.
Income tax: the deferred gain comes due at death
The estate tax benefit does not carry over to income tax. Congress addressed cancellation directly:
- §453B(f) treats a cancelled installment obligation as disposed of, and if the parties are related, its value is treated as not less than face.
- §691(a)(5)(A)(iii) says a cancellation "occurring at the death of the decedent shall be treated as a transfer by the estate of the decedent," and §691(a)(5)(B) sets the value at not less than face when the parties are related.
In practice, the unreported gain on the cancelled balance becomes income in respect of a decedent, reported by the estate. The Eighth Circuit applied this in Frane v. Commissioner, 998 F.2d 567 (8th Cir. 1993), treating the gain from cancelled SCINs as income of the estate rather than something that vanished.
The buyer keeps the property with a cost basis equal to the full stated price, even though part of it was never paid.
Simple example: a SCIN cancelled after four years
Simple example. Assumptions: you sell land worth $2,000,000 with a $500,000 basis to your son for a 10-year SCIN at an assumed 7% rate that includes a risk premium. No depreciation, no other liabilities. Annual payments of $284,755. You die right after the fourth payment.
| Year | Payment | Interest | Principal | Balance after |
|---|---|---|---|---|
| 1 | $284,755 | $140,000 | $144,755 | $1,855,245 |
| 2 | $284,755 | $129,867 | $154,888 | $1,700,357 |
| 3 | $284,755 | $119,025 | $165,730 | $1,534,627 |
| 4 | $284,755 | $107,424 | $177,331 | $1,357,296 |
- Gross profit percentage: ($2,000,000 minus $500,000) divided by $2,000,000 = 75%.
- Principal received during life: $642,704, of which $482,028 was reported as gain.
- Balance cancelled at death: $1,357,296. Deferred gain on it: $1,017,972, reported by your estate under §691(a)(5).
- Estate tax: under Moss, the cancelled $1,357,296 is not in your gross estate. The payments you already received (and did not spend) are.
The estate tax saving is 40% of whatever would otherwise have been included, but only if the estate is above the $15,000,000 exclusion for 2026 (§2010(c)(3)). The income tax on the $1,017,972 is owed either way.
Now reverse it. If you outlive the note term, the buyer pays the full price plus the premium. That premium moves extra money into your estate, the opposite of what you wanted. A SCIN is a bet on dying before the note is paid.
Pricing the premium: the valuation fight
The premium must reflect the real chance you die during the term. Advisors often use the IRS mortality tables under §7520 to size it. Those tables are generally required only when the seller is not "terminally ill" as defined in the regulations, and even then the IRS has pushed back.
In CCA 201330033 (released 2013), IRS Chief Counsel concluded: "We do not believe that the § 7520 tables apply to value the notes in this situation," and said the valuation "should also account for the decedent's medical history on the date of the gift." The memo also concluded there was a deemed gift if the notes were worth less than the stock sold. Chief Counsel memos are not precedent, but they show where an audit will go.
| Factor | Why it matters |
|---|---|
| Your actual health | A seller who is seriously ill at signing invites a gift or sham argument |
| Term vs life expectancy | A term longer than life expectancy looks like a disguised annuity |
| Size of premium | Too small and part of the sale is a gift |
| Buyer's ability to pay | A buyer who cannot pay suggests the note is not real debt |
| Security | Collateral and a payment history support bona fide debt |
SCIN vs other family transfer tools
| Tool | Income tax on sale | Estate result if you die early | Main risk |
|---|---|---|---|
| Plain installment sale to family | Gain as paid | Unpaid note is in your estate | §453(e) resale rule |
| SCIN | Gain as paid; remainder taxed to estate at death | Cancelled balance out of estate | Premium sizing, gift challenge |
| Private annuity | Proposed regs tax gain up front | Payments stop, nothing left | 2006 proposed regs |
| IDGT sale | None while grantor trust | Unpaid note in estate; growth out | Lost step-up |
Interest on a SCIN should be at least the applicable federal rate for the term. See seller financing interest rates and the AFR. For the basic mechanics of reporting payments, see the installment sale guide, or model the payment stream in the calculator.
Bottom line
A SCIN can keep an unpaid balance out of your estate if you die early, but the buyer pays for that with a premium, the IRS may challenge the pricing if your health was poor, and your estate still owes income tax on the deferred gain. It fits a seller with a real estate tax exposure, shorter-than-average life expectancy without a terminal diagnosis, and a family buyer who can make the payments.
Questions to ask your CPA
- Is my estate large enough that removing the unpaid balance saves estate tax?
- How should the premium be set, and will it hold up given my health today?
- Should the premium go into the price or the interest rate?
- How much income tax will my estate owe on the deferred gain if the note cancels?
- What happens to the premium I collect if I outlive the note?
- Would a plain installment sale, an IDGT or a gift plan do the job with less risk?
