The buyer is offering a higher overall enterprise valuation if we agree to a zero-interest seller note for the financed portion. How does the IRS imputed interest rule under Section 483 affect this structure, and how do we negotiate the minimum interest rate to avoid a surprise tax recharacterization?

While a higher headline enterprise valuation looks great on paper, a zero-interest seller note is a trap. The IRS does not allow interest-free loans in business transactions. Under Section 483 and Section 1274, if a seller note does not state an adequate interest rate, the IRS will impute interest on the payments. This means they will recharacterize a portion of your capital gains, which are taxed at lower rates, as ordinary interest income, which is taxed at higher ordinary income rates.

To avoid this surprise tax recharacterization, you must ensure the seller note carries an interest rate at least equal to the applicable federal rate, or AFR, published monthly by the IRS. Negotiating the AFR as your minimum interest rate ensures the entire principal remains classified as capital gains, preserving your net proceeds.

When structuring this, present a clear amortization schedule to the buyer showing that the minimum required interest rate is built into the payments. This keeps your transaction clean and compliant. In your V/TO planning, you must calculate your actual net post-tax yield rather than focusing solely on the gross enterprise value. Do not let a buyer inflate their paper valuation of your business while shifting your tax burden from capital gains to ordinary income. Work with your CPA to run the numbers before finalizing any terms in the purchase agreement.
