Lending money to a family member is one of the most generous things you can do — and one of the easiest ways to accidentally create a tax problem. If you charge too little interest (or none at all), the IRS may treat the missing interest as a taxable gift. The key benchmark is the applicable federal rate for a family loan, published monthly by the IRS. Understanding how these rates work in 2026 can save you thousands in unexpected gift taxes and keep your intra-family lending clean from a compliance standpoint.
Whether you’re lending $15,000 to help a sibling cover medical bills or $250,000 to fund your child’s home purchase, the AFR is the floor interest rate the IRS expects to see. Ignore it, and the consequences range from imputed interest income on your tax return to eating into your lifetime gift tax exclusion — currently $13.61 million per individual in 2026, according to the Internal Revenue Service.
Key Takeaways
- The IRS publishes applicable federal rates monthly in three term categories: short-term (≤3 years), mid-term (3–9 years), and long-term (>9 years).
- Charging below the AFR on a family loan can trigger imputed interest and gift tax consequences for the lender.
- For July 2026, AFRs remain historically moderate — typically between roughly 3% and 5% depending on the loan term and compounding method.
- A written loan agreement specifying at least the AFR protects both parties from IRS reclassification of the loan as a gift.
- Loans under $10,000 are generally exempt from the AFR imputed interest rules, and loans between $10,000 and $100,000 receive a limited exception tied to the borrower’s net investment income.
What is the applicable federal rate, and why does the IRS require it?
The applicable federal rate (AFR) is the minimum interest rate the IRS requires on private loans to prevent families from disguising gifts as zero-interest or below-market loans. Published monthly in an IRS Revenue Ruling, AFRs are broken into short-term (up to 3 years), mid-term (over 3 to 9 years), and long-term (over 9 years), each with annual, semiannual, quarterly, and monthly compounding options.
The legal authority comes from Internal Revenue Code Section 7872, which governs below-market loans. Under Section 7872, if a lender charges less than the AFR, the IRS “imputes” interest — meaning it treats the lender as having received the AFR interest income regardless of what was actually collected. The difference between what the lender charged and the AFR is then treated as a gift from the lender to the borrower.
Here’s why that matters in concrete terms:
- Imputed income: The lender must report the imputed interest as taxable income, even though they never received the money.
- Gift tax filing: If the imputed interest exceeds the annual gift tax exclusion ($19,000 per recipient in 2026), the lender must file IRS Form 709.
- Lifetime exclusion erosion: Large below-market loans can chip away at the lender’s $13.61 million lifetime gift and estate tax exemption.
How do you find the correct AFR for your family loan in 2026?
You find the correct AFR by checking the IRS Revenue Ruling for the month in which the loan is made. Visit the IRS website and search “applicable federal rates” — they’re published as a table in each month’s Revenue Ruling. Choose the rate that matches your loan’s term length and your preferred compounding frequency.
Here’s a simplified breakdown of how to match the right rate:
| Loan Duration | AFR Category | Typical 2026 Range |
|---|---|---|
| 3 years or fewer | Short-term | ~3.50%–4.25% |
| Over 3 to 9 years | Mid-term | ~3.75%–4.50% |
| Over 9 years | Long-term | ~4.25%–5.00% |
Note: These ranges are illustrative based on recent trends. Always verify the exact rate for your loan month on the IRS website.
A few practical tips that most guides miss:
- Lock your rate at origination. You can use either the AFR from the month you fund the loan or the AFR from either of the two preceding months — whichever is lowest. This gives you a small window to shop for the best rate.
- Choose your compounding wisely. Annual compounding produces the lowest stated rate. Monthly compounding results in a slightly higher rate. For most family loans, annual compounding keeps things simple and keeps the rate as low as possible.
- Demand notes use the short-term rate — even if the borrower takes 10 years to repay. If you want to use the lower short-term rate, structure the loan as a term loan of 3 years or less, not a demand note that could stretch indefinitely.
What happens if you charge zero interest or skip the AFR?
If you charge zero interest or a rate below the applicable federal rate, the IRS treats the forgone interest as a deemed gift from lender to borrower. The lender owes income tax on interest they never collected, and may also owe gift tax or need to file Form 709 — even on a loan both parties consider entirely legitimate.
Let’s walk through a real-world example. Suppose in 2026 you lend your daughter $200,000 at 0% interest for 15 years to help with a home purchase. The long-term AFR (let’s say 4.50% annually compounded) would generate roughly $9,000 in imputed interest in year one alone. That $9,000 is treated as:
- Taxable interest income to you, reportable on your Form 1040.
- A gift from you to your daughter, potentially requiring a Form 709 filing if combined with other gifts it exceeds $19,000 for the year.
Over 15 years, the total imputed interest could exceed $100,000 — all of it phantom income you never actually received but must report. This is the most common and most costly mistake we see among families who lend without a proper agreement.
There are, however, two important safe harbors:
- De minimis exception: Loans of $10,000 or less are generally exempt from the imputed interest rules, provided the loan isn’t used to purchase income-producing assets.
- $100,000 exception: For loans between $10,001 and $100,000, imputed interest is limited to the borrower’s net investment income for the year. If the borrower’s net investment income is $1,000 or less, it’s treated as zero — meaning no imputed interest applies.
Understanding these thresholds can save a family significant tax exposure. For a deeper look at how the IRS distinguishes loans from gifts, see our guide on how the IRS treats family money transfers.
How do you structure a family loan to stay IRS-compliant in 2026?
To stay IRS-compliant, create a written promissory note that specifies the principal amount, a stated interest rate at or above the AFR, a fixed repayment schedule, and consequences for default. Both parties should sign it before funds are transferred, and payments should flow through traceable bank transfers — never cash.
Here’s a step-by-step checklist:
- Look up the AFR for your loan month on the IRS website. Choose the correct term category and compounding period.
- Draft a written agreement that includes: loan amount, interest rate (at or above the AFR), repayment schedule (monthly, quarterly, or annual), maturity date, and what happens if the borrower can’t pay.
- Fund the loan via bank transfer — wire, ACH, or check. Create a clear paper trail.
- Report the interest. The lender reports received interest as income on Schedule B of Form 1040. The borrower may be able to deduct interest if the loan is secured by their home (consult a tax professional).
- Keep records for at least 7 years — the agreement, proof of transfers, and evidence of repayment.
One nuance many families overlook: if you want to forgive portions of the loan over time — say, $19,000 per year as a gift — document the forgiveness in writing each year. The Consumer Financial Protection Bureau emphasizes the importance of clear documentation in any lending arrangement, and the IRS applies even greater scrutiny to intra-family transactions.

Frequently Asked Questions
Can you charge more than the applicable federal rate on a family loan?
Yes. The AFR is a minimum, not a cap. You can charge any rate above the AFR. Some families set the rate at the AFR to minimize the borrower’s cost while satisfying IRS requirements. Others set it slightly higher to earn modest income. There is no federal maximum interest rate, though state usury laws may apply.
Does the AFR apply to loans between friends, or only family members?
Section 7872 applies to any below-market loan between related parties, including family members, employers and employees, and certain trust arrangements. Loans between friends can also trigger imputed interest rules if the IRS determines there is a gift element. A written agreement at or above the AFR protects any private loan.
What if the borrower defaults on a family loan made at the AFR?
If the borrower defaults, the lender may be able to claim a nonbusiness bad debt deduction, reported as a short-term capital loss on Schedule D. To qualify, the lender must prove the loan was a bona fide debt — a written agreement at the AFR is essential evidence. Without documentation, the IRS will likely treat the amount as a non-deductible gift.
Do you need to charge interest on a family loan under $10,000?
Generally no. IRC Section 7872(c)(3) exempts loans of $10,000 or less from imputed interest rules, as long as the loan proceeds aren’t used to buy income-producing investments. However, putting even a small loan in writing protects the relationship and establishes that it’s a loan, not a gift.
Where can you find a template for an AFR-compliant family loan agreement?
You can find templates from legal document services or use a purpose-built platform designed for family and friend lending. The critical elements are: loan amount, AFR-compliant interest rate, repayment terms, signatures, and the date. A properly structured agreement makes tax reporting straightforward and protects both parties. See our guide on why you should put a family loan in writing.
What’s the bottom line on AFR and family lending?
The applicable federal rate for a family loan isn’t just a technicality — it’s the line between a tax-compliant transaction and an accidental gift with real financial consequences. In 2026, with AFRs still moderate by historical standards, it’s relatively inexpensive for borrowers to pay compliant interest. The hard part isn’t the rate — it’s making sure everything is documented properly.
A written agreement protects the lender’s tax position, preserves the borrower’s ability to claim deductions where applicable, and — perhaps most importantly — keeps the family relationship intact when money is involved.
