9013 / What are self-cancelling installment notes (SCINs)? How can SCINs be used in family business succession planning?

Under a self-cancelling installment note (SCIN), the selling business owner agrees to sell property to a buyer (often, the owner’s children or other beneficiaries) in exchange for an installment note that expires either when the seller receives the maximum price for the property or upon the occurrence of a cancellation event, such as the seller’s death. This is a form of installment sale transaction (see Q 9007). It allows the seller to secure the purchase for the business interest, while still retaining the ability to defer part of the gain.¹ In turn, the buyer can claim an interest deduction with respect to the payments made.² See Q 8027 for a discussion of the new rules governing the deduction for business interest under the 2017 tax reform legislation.

Under a SCIN, if the cancelling event is the selling business owner’s death, all remaining payments under the note are canceled upon the seller’s death, similar to a private annuity. Typically, the purchaser pays a premium for this cancellation feature in the form of either a higher interest rate or a larger purchase price. Gain under a SCIN is recognized by the selling business owner as payments are received. However, when the seller dies, any unrecognized (i.e., cancelled) gain at the seller’s death under the SCIN is reportable either on the seller’s final IRS Form 1040 or on the seller’s estate’s IRS Form 1041.

In order for the IRS to recognize the SCIN, the term of the note must be shorter than the seller’s life expectancy at the time of the sale, based on IRS mortality tables.³ The advantage of using a SCIN, as opposed to other installment sale methods or an intentionally defective grantor trust (see Q 9012), is that the unpaid balance is not included in the seller’s estate.⁴
