We want to structure our exit as a Section 453 installment sale to defer capital gains tax, but we are worried about how interest rates on the unpaid balance will affect our net proceeds. How do we structure the interest rate and payment schedule on the seller note to optimize our tax benefits?

A Section 453 installment sale is an excellent tool for deferring your tax liability, but the structure of the interest rate on your seller note is highly sensitive. The IRS requires you to charge an adequate rate of interest, known as the Applicable Federal Rate. If you set the interest rate too low, the IRS will recharacterize a portion of your principal payments as imputed interest, which is taxed at higher ordinary income rates rather than lower capital gains rates. To optimize your net proceeds, you want to negotiate a market-rate interest payment schedule that pays down the note efficiently. Structure the note with a floating interest rate pegged to a reliable benchmark, such as the prime rate plus a spread, with a floor to protect you if rates drop. To manage the risk of buyer default, make sure the installment note payment dates are hardcoded and align with your post-close cash flow planning. You should also demand a cash-flow sweep covenant. This means if the business exceeds certain financial metrics on its quarterly EOS Scorecard, a percentage of that excess cash flow is automatically swept to prepay your note. This reduces your exposure quickly while deferring your capital gains taxes over multiple tax years as the cash is actually received.
