Below-Market Loans and Imputed Interest (§ 7872)

IRC § 7872 is the rule that says you can't make an interest-free loan to a family member, employee, or shareholder without tax consequences. Enacted as part of the Deficit Reduction Act of 1984, it requires that any loan below the IRS's applicable federal rate (AFR) — published monthly — be treated as if the forgone interest was paid and then re-transferred to the borrower as a gift, wages, or dividend. The borrower doesn't actually pay a dollar of interest, but the tax system behaves as if they did.

Before § 7872, a wealthy parent could lend a child $1 million interest-free indefinitely, effectively gifting the investment return the parent could have earned on that money with no gift tax. A corporation could extend an "interest-free loan" to a shareholder that was economically a dividend without the corporate-level tax. Congress closed both gaps in 1984. The statute has two important safe harbors: loans of $10,000 or less are entirely exempt, and gift loans between individuals of $100,000 or less are only imputed to the extent of the borrower's net investment income (zero if that income is $1,000 or less). For most families, those thresholds cover routine intra-family help. For larger transfers, charging at least the AFR is the clean solution — and in estate planning, AFR loans to trusts are a deliberate strategy to move appreciation out of a taxable estate without using gift tax exemption.

Current Law (2026)

Legal Authority

• 26 U.S.C. § 7872(a) — Below-market loans treated as if made at the AFR; foregone interest treated as a transfer from lender to borrower, then retransferred as interest back to lender
• 26 U.S.C. § 7872(b) — Term loans: the foregone interest (the excess of amount loaned over the present value of required payments discounted at the AFR) is a deemed transfer on the date of the loan
• 26 U.S.C. § 7872(c) — Categories: gift loans; compensation-related loans; corporation-shareholder loans; tax avoidance loans
• 26 U.S.C. § 7872(d) — Exceptions: $10,000 de minimis exemption; $100,000 gift loan cap on imputed interest (limited to borrower's net investment income)
• 26 U.S.C. § 7872(f) — Applicable federal rate: the rate published under § 1274(d); the AFR varies by loan term and is updated monthly
• 26 U.S.C. § 7872 (DB) — Treatment of loans with below-market interest rates: loans to continuing care facilities get special age-based exceptions when the lender (or spouse) reaches age 65 (or age 62 in other cases), up to $90,000 (adjusted for cost-of-living for loans after 1986); the Treasury can make rules to fix odd cases, ensure consistent treatment for borrower and lender, and exempt transactions that don't affect federal taxes; "amount loaned" means what the borrower received; "net investment income" uses the definition in § 163(d)(4)

Key Mechanics

The core rule: If you make a loan below the applicable federal rate (AFR), the IRS treats the foregone interest — the difference between what you charged and what the AFR would require — as if it were actually paid, then re-transferred to the borrower as an appropriate deemed payment. Two things happen simultaneously: the lender is treated as having received the AFR interest (taxable income), and the lender is treated as having transferred that same amount to the borrower (a gift, compensation, or dividend depending on the relationship).

Demand loans vs. term loans work differently. A demand loan (repayable any time) accrues imputed interest annually — you recalculate each year based on the current short-term AFR and the outstanding balance. A term loan (fixed repayment schedule) is handled entirely upfront: on the date of origination, the IRS computes the present value of all required payments discounted at the AFR, and the difference between the loan amount and that present value is a deemed transfer on day one. Term loans can therefore produce a large, immediate imputed transfer even if the loan is later forgiven or repaid.

The AFR tiers: The IRS publishes three AFR rates monthly under § 1274(d). Short-term AFR applies to loans of three years or less; mid-term to loans of three to nine years; long-term to loans over nine years. Using the wrong tier (e.g., applying the short-term rate to a 10-year family loan) doesn't automatically trigger § 7872 — but only if the correct tier rate is used will there be zero imputed interest.

The two safe harbors: The $10,000 de minimis exception is unconditional — any loan of $10,000 or less between any parties is completely outside § 7872. The $100,000 gift-loan exception applies to loans between individuals of $10,001–$100,000: imputed interest is capped at the borrower's net investment income for the year, and drops to zero if that net investment income is $1,000 or less. These thresholds have not been adjusted for inflation since 1984, when $10,000 had roughly four times the purchasing power it does today.

How It Works

Section 7872 works by treating a below-market loan as if the lender made the loan at the AFR and then simultaneously made a deemed transfer to the borrower equal to the foregone interest. The tax consequence of that deemed transfer depends on the relationship between lender and borrower:

Gift loans (between family members or other situations where the foregone interest is intended as a gift): the foregone interest is a deemed gift from the lender to the borrower. Each year, the lender is treated as giving the borrower the AFR interest that was not charged — this amount reduces the lender's annual gift tax exclusion ($19,000 per recipient in 2026) and may require a gift tax return if the imputed interest plus other gifts to that recipient exceeds the exclusion. The borrower has no interest deduction (since no interest was actually paid), but also no income from the forgiven interest.

Compensation loans (employer to employee): if a business lends money to an employee at below-market rates, the foregone interest is compensation — ordinary income to the employee subject to income tax and payroll taxes, and a deductible compensation expense for the employer. This is commonly seen in relocation loans or housing assistance programs where employers provide below-market financing to key employees.

Shareholder loans (corporation to shareholder): foregone interest from a corporation to a majority shareholder is treated as a dividend to the shareholder and is not deductible by the corporation. The double-tax cost (corporate tax on earnings, then dividend tax on the forgiven interest) makes below-market shareholder loans expensive in comparison to simply charging market-rate interest.

The $10,000 de minimis exception is absolute: loans of $10,000 or less between any parties are completely exempt from § 7872, with no imputed interest regardless of relationship. A parent can lend a child $10,000 interest-free with no tax consequences whatsoever.

The $100,000 gift loan exception is more nuanced: for gift loans between individuals of $100,000 or less (but more than $10,000), the imputed interest is limited to the borrower's net investment income for the year — and is zero if net investment income doesn't exceed $1,000. Net investment income includes dividends, interest, and capital gains from the borrower's portfolio. A child borrowing $80,000 interest-free from a parent who has minimal investment income owes no imputed interest under § 7872 — the practical effect is that small intra-family loans for home purchases, education, or business needs are largely immune from § 7872 when the borrower is a young adult with a modest investment portfolio.

AFR-based planning: The AFR is the critical pricing benchmark. Loans at or above the AFR have no § 7872 implications — the interest charged is real income to the lender and potential interest expense for the borrower. Intra-family loans at the AFR are therefore a legitimate wealth transfer tool when used strategically: by lending to a trust or family member at the current AFR (which can be quite low in low-rate environments), the lender allows the borrower to invest in assets expected to appreciate faster than the AFR — the spread between the investment return and the AFR rate accrues to the borrower without gift tax. A $500,000 loan to a Spousal Lifetime Access Trust (SLAT) at a 3% AFR, where the trust invests in assets returning 7% annually, transfers approximately 4% per year of the trust's assets ($20,000 in year one, growing with the trust) to the next generation gift-tax free.

How It Affects You

If you want to lend money to a family member: Keep the loan at or below $10,000 for a completely tax-free interest-free arrangement. For loans between $10,001 and $100,000, charge zero interest but ensure the family member's net investment income is low (under $1,000) to avoid any imputed gift — if they have significant investment portfolios, you'll need to impute at least some interest. For loans above $100,000, charge the applicable AFR to avoid the imputed gift entirely. Document the loan with a written promissory note, establish a repayment schedule, and keep records of actual payments — this also protects against the IRS reclassifying the "loan" as a gift (which would use your gift tax exclusion) if the family member never repays.

If you want to use an intra-family loan for estate planning: An AFR loan to a trust or family member is one of the most efficient wealth transfer techniques in periods when the AFR is lower than expected investment returns. Lend at the current mid-term or long-term AFR; the trust or family member invests in assets expected to appreciate faster. The interest you receive back is income to you (taxable at ordinary income rates), but all appreciation above the AFR stays in the trust or with the family member without gift tax. The loan itself does not use your gift tax lifetime exemption. When rates are low (as they were in 2020-2022, when the long-term AFR fell below 2%), this technique can transfer substantial wealth with minimal gift tax cost.

If your employer provides below-market or interest-free loans: Understand that the foregone interest is income to you — it will appear on your W-2 as compensation in the amount of the AFR interest on the outstanding loan balance. You'll owe income tax and payroll tax on that amount even though you didn't receive any cash. If your employer is offering a relocation loan or housing assistance loan at below-market rates, the imputed compensation cost is a real cost to you that should be factored into your total compensation analysis.

If you're running a closely held corporation and have outstanding loans to shareholders: Review whether those loans are at or above the AFR. If they are interest-free or below-AFR, the corporation has a phantom dividend equal to the foregone interest — taxable to the shareholder, not deductible by the corporation. Charging the AFR on shareholder loans is a simple compliance step that eliminates this issue and provides the corporation with legitimate interest income.

State Variations

Most states follow federal § 7872 imputed interest treatment for state income tax purposes. California, New York, and other high-income-tax states treat imputed interest income (to the lender) and the corresponding deemed transfers (gifts, compensation, dividends) consistently with federal treatment. There is no state-level version of the § 7872 de minimis exceptions — the $10,000 and $100,000 federal thresholds apply for federal purposes, and state conformity is generally automatic.

What to Watch

Three variables drive § 7872 planning and risk for most households:

1. Monthly AFR movement: The IRS releases new AFR tables around the 20th of each month for the following month. If you're structuring an intra-family loan or trust loan, the rate you lock in at origination for a term loan is fixed — so timing matters. In rising-rate environments, locking in a low long-term AFR before the next increase can be worth thousands of dollars in annual interest savings.

2. Estate tax lifetime exemption changes: The TCJA doubled the lifetime gift and estate tax exemption, which is scheduled to revert to roughly $7 million (inflation-adjusted) after December 31, 2025 unless Congress acts. If exemptions shrink, AFR-based trust loans become more attractive relative to outright gifts, because the loan strategy doesn't consume exemption. Watch for estate tax legislation in late 2025 and 2026.

3. IRS enforcement on family loan reclassification: The IRS sometimes reclassifies purported "loans" as gifts when the family member never repays and there was no real intent to collect. A written promissory note, evidence of some repayments, and a realistic repayment schedule are the practical defenses. IRS audit activity in this area tends to rise when estate tax rates are higher or exemptions are lower.

Pending Legislation

No significant § 7872 reform legislation is pending as of 2026. Proposals to raise or lower the de minimis thresholds (unadjusted for inflation since 1984) appear occasionally in tax simplification discussions. The OBBBA did not include changes to § 7872. Broader estate tax reform proposals that would limit intra-family loan strategies have not advanced.

Recent Developments

• AFR volatility and estate planning: The AFR rose significantly in 2022–2023 as the Federal Reserve raised interest rates, making AFR-based intra-family loans more expensive (lenders must charge higher rates to avoid imputation) but also reducing the spread between AFR and portfolio returns for planning purposes. In 2020–2021, when the long-term AFR was below 2%, intra-family trust loans were particularly attractive. Tax advisors monitor the monthly AFR closely when structuring trust loans and grantor retained annuity trusts (GRATs).
• Cryptocurrency loans and § 7872: The rise of cryptocurrency lending platforms has raised questions about whether crypto-denominated loans are subject to § 7872. The IRS has indicated that cryptocurrency is property, not currency — so AFR rules applicable to dollar-denominated loans may not directly apply to crypto-denominated loans, though the tax avoidance purpose provision of § 7872(c)(1)(D) could capture below-market crypto loans with a tax avoidance purpose.
• COVID-era employer loans: Several employers during 2020–2021 provided forgivable loans to employees as an alternative to direct grants, leveraging the ability to forgive loans at a later date. Employer forgivable loans at below-market rates raised § 7872 and forgiveness income questions. IRS guidance confirmed that forgiven loan amounts are compensation income in the year of forgiveness, and below-market interest components generate imputed compensation annually.
