Sage loaned their friend $7,000 to buy a used car. They had their friend sign a note with repayment terms and set a reasonable interest rate on the note because they wanted their friend to understand that this was purely a loan and not a gift. Their friend is now on disability and has made it clear that the loan will not be repaid. How should Sage treat the bad loan for tax purposes?
