The Applicable Federal Rate (AFR) is a rate published monthly by the IRS for federal income tax purposes.
The IRS will treat any “loan” with a below market interest rate (below the AFR) as a gift of the foregone interest from the lender to the borrower. The amount of the foregone interest will be treated as though it was transferred from the lender to the borrower as a gift and retransferred from the borrower to lender as income on the last day of the calendar year.
