Tax Implications of Personal Loans — What Lenders & Borrowers Should Know

When you lend money to a friend or family member, taxes are probably the last thing on your mind. But depending on the amount and whether you charge interest, there can be real tax implications for both the lender and the borrower. Understanding these rules can save you from an unpleasant surprise at tax time.

For Borrowers: The Good News -- In most countries, money you borrow is not considered taxable income. Whether you borrow $100 from a friend or $10,000 from a family member, you do not have to report the loan as income on your tax return. This applies regardless of whether the loan is formal or informal, documented or verbal. The key distinction is that a loan is expected to be repaid, which is what separates it from income or a gift.

For Lenders: Interest Income Is Taxable -- If you charge interest on a personal loan, the interest you receive is generally considered taxable income. In the United States, if you earn more than $600 in interest in a year, you may need to report it. Even for smaller amounts, the interest is technically taxable income, though enforcement on small amounts is minimal. Keep records of all interest payments received.

The Gift Tax Consideration -- Here is where it gets tricky. If you lend a large amount to someone and charge zero interest or below-market interest, the IRS may consider the forgone interest as a gift from the lender to the borrower. For 2026, the annual gift tax exclusion is $18,000 per person. So if you make an interest-free loan of $100,000, the imputed interest (what you would have earned at market rates) could be considered a gift. For most personal loans between friends, the amounts are small enough that this is not a concern.

Forgiven Debt Can Be Taxable -- If you lend someone $5,000 and later decide to forgive the debt, the IRS may consider that forgiven amount as income to the borrower. For amounts over $600, the lender may need to file a Form 1099-C (Cancellation of Debt). The borrower would then need to report the forgiven amount as income on their tax return. This is important to know before casually telling a friend "do not worry about paying me back."

Documenting Your Loans -- Proper documentation is your best protection from tax issues. A written agreement showing that the transaction is a loan, not a gift, protects both parties. It should clearly state the amount, repayment terms, and any interest. NowTo IOU provides timestamped records that can serve as supporting documentation, showing that the transaction was intended as a loan with an expectation of repayment.

When to Consult a Tax Professional -- For small personal loans, say under $1,000, the tax implications are minimal and you generally do not need professional advice. But consider consulting a tax professional if the loan amount exceeds $10,000. If you are charging interest on any personal loan. If you plan to forgive a debt of any significant amount. If you are making international personal loans. If you are lending to someone in a business capacity.

Key Takeaways -- Borrowing money from friends is generally not taxable income. Interest earned on personal loans is taxable income for the lender. Very large interest-free loans may trigger gift tax rules. Forgiven debts over $600 may be taxable income for the borrower. Good documentation protects both parties. When in doubt, consult a tax professional.
