Lending to Family or Friends? Know the Tax Rules
Helping a family member or close friend financially can be a generous way to provide support when they need it most. Maybe they need money for a home down payment, want to start a business, or simply need temporary financial assistance.
But when you lend money to someone you know, especially at little or no interest, the IRS may have tax rules that apply to the transaction.
A casual agreement such as “pay me back whenever you can” may seem harmless, but failing to properly structure a personal loan can create unexpected tax consequences. Understanding the rules before you transfer the money can help protect both your relationship and your finances.
What Is a Below-Market Loan?
The IRS has specific rules for below-market loans, which generally apply when a loan is made with little or no interest.
If you lend money to a family member or friend without charging an appropriate amount of interest, the IRS may treat the transaction differently than you expect.
In certain circumstances, the tax rules can result in imputed interest, meaning the IRS calculates interest that is treated as though it had been charged—even if you never actually received that interest.
Depending on the circumstances, the transaction can also have gift tax implications.
That’s why an informal, interest-free loan can become much more complicated from a tax perspective.
Why You Should Treat a Personal Loan Like a Real Loan
If you want to lend a significant amount of money to someone close to you, it’s important to establish that the transaction is actually a loan and not simply a gift.
A properly structured loan should generally include:
- A written promissory note
- A clearly stated interest rate
- A specific repayment schedule
- Payment due dates
- Principal and interest amounts
- Terms for late or missed payments
- Appropriate security or collateral when applicable
Putting everything in writing protects both parties and provides documentation if the IRS ever questions the transaction.
A handshake may be fine for many personal arrangements, but it isn’t a substitute for proper documentation when significant money is involved.
What Is the Applicable Federal Rate?
One of the most important concepts to understand when lending money to family or friends is the Applicable Federal Rate (AFR).
The IRS publishes AFRs each month. These rates are used for a variety of tax purposes, including determining whether certain loans are considered below-market loans.
The appropriate AFR depends on factors such as:
- The term of the loan
- The repayment structure
- The month the loan is made
For that reason, you shouldn’t simply choose an interest rate because it “sounds reasonable.”
The appropriate AFR should be determined when the loan is established.
Example Scenario
Imagine you lend a family member $100,000 to help with a home purchase.
You agree that they will pay you back over several years but decide not to charge interest because you want to help them.
From your perspective, you’re simply helping a loved one.
However, depending on the circumstances, the IRS may apply the below-market loan rules and calculate interest that should have been charged.
That could create unexpected tax consequences even though you never received interest payments.
Instead, you could establish a written promissory note with an appropriate interest rate that meets the applicable IRS requirements.
The family member gets access to the financing they need, while you have a documented repayment arrangement and a clearer tax position.
Is Lending Money the Same as Giving a Gift?
Not necessarily.
A loan is generally expected to be repaid, while a gift is a transfer made without the expectation of repayment.
This distinction matters.
If you tell someone they never have to repay the money, the transaction may be treated as a gift rather than a loan. If you call something a loan but there is no realistic expectation of repayment, that can also create problems.
If the amount is substantial, you should carefully document the arrangement and understand the potential gift tax implications.
What If the Borrower Stops Making Payments?
This is another reason to establish clear terms before lending the money.
Your promissory note should explain what happens if the borrower:
- Misses a payment
- Stops making payments
- Defaults on the loan
- Sells the collateral
- Files for bankruptcy
It can be uncomfortable to discuss these situations with a family member or friend, but having clear expectations from the beginning can prevent significant financial and personal problems later.
A properly documented loan also helps demonstrate that the arrangement was intended to be a genuine loan.
Don’t Forget About Your Own Tax Reporting
Receiving interest from a personal loan generally creates taxable interest income for the lender.
If you charge interest, you’ll need to properly account for that income on your tax return.
On the other hand, simply avoiding interest doesn’t necessarily eliminate tax considerations. The below-market loan rules may cause the IRS to impute interest in certain circumstances.
That’s why the tax treatment should be considered before the money changes hands—not after the first payment is missed.
Why Planning Matters
Lending money to family or friends can be rewarding, but it also combines personal relationships with financial and tax responsibilities.
Before making a significant personal loan, consider:
- Whether the transaction is truly a loan or a gift
- The appropriate Applicable Federal Rate
- Creating a written promissory note
- Establishing a realistic repayment schedule
- Documenting all payments
- Understanding potential gift tax consequences
- Considering collateral when appropriate
- Understanding the tax treatment of interest income
Taking these steps doesn’t mean you don’t trust your family member or friend. It simply means you’re protecting everyone involved.
Conclusion
Helping someone you care about financially doesn’t have to create an unnecessary tax headache.
If you’re lending money to a family member or friend, especially a substantial amount, don’t rely on a handshake agreement or assume that an interest-free loan is automatically tax-free.
By properly documenting the loan, using the appropriate Applicable Federal Rate, and understanding the IRS rules for below-market loans, you can provide financial assistance while protecting your own wealth and tax position.
