H1

AFR Rates (Applicable Federal Rates)

---

ANSWER SECTION

Applicable Federal Rates (AFR) are minimum interest rates set monthly by the IRS for federal income tax purposes. These rates apply to loans between related parties (like family members), installment sales, certain deferred compensation arrangements, and private annuities. If you lend money to a family member and charge less than the AFR, the IRS may impute interest income to you—meaning you'll owe taxes on interest you never actually received.

H2: Current AFR Rates (March 2026)

The IRS publishes three tiers of rates based on loan term:

Short-Term AFR (0-3 years):

Period	Annual	Semiannual	Quarterly	Monthly
March 2026	4.25%	4.20%	4.18%	4.17%

Mid-Term AFR (3-9 years):

Period	Annual	Semiannual	Quarterly	Monthly
March 2026	4.15%	4.11%	4.09%	4.08%

Long-Term AFR (Over 9 years):

Period	Annual	Semiannual	Quarterly	Monthly
March 2026	4.50%	4.45%	4.43%	4.42%

Section 7520 Rate (for annuities, life estates): 4.80%

Rates are published monthly in IRS Revenue Rulings. These are representative rates for March 2026.

H2: How AFR Rates Work

The Imputed Interest Rule: When you make a below-market loan (charging less than AFR), the IRS treats the transaction as if:

1. You received interest income at the AFR rate
2. You made a gift of the forgone interest to the borrower

Example:

• You lend your child $100,000 for 5 years at 1% interest
• Mid-term AFR is 4.15%
• Imputed interest: $100,000 × (4.15% - 1%) = $3,150 per year
• You report $3,150 as interest income (even though you didn't receive it)
• The $3,150 may also count against your lifetime gift tax exclusion

Exceptions to Imputed Interest:

• Loans of $10,000 or less (gift loans)
• Loans of $100,000 or less where borrower's investment income is $1,000 or less
• Loans for acquiring a home (certain family loans)
• Compensation-related and corporation-shareholder loans with de minimis exceptions

H2: Common Uses of AFR Rates

1. Family Loans:

• Parent-to-child home down payment loans
• Loans between siblings
• Business startup funding from family

2. Installment Sales:

• Seller-financed real estate transactions
• Business sales with deferred payments
• Must use AFR or higher to avoid recharacterization

3. Grantor Retained Annuity Trusts (GRATs):

• Estate planning tool using the Section 7520 rate
• If investments outperform the AFR, excess passes to heirs gift-tax-free

4. Charitable Gift Annuities:

• Payments calculated using Section 7520 rate
• Affects charitable deduction amount

5. Intrafamily Sales to Intentionally Defective Grantor Trusts (IDGTs):

• Advanced estate planning strategy
• Freeze asset values using low AFR rates

H2: AFR Rate Planning Strategies

When Rates Are Low (like 2020-2021):

• Lock in long-term family loans at low rates
• Create GRATs for estate planning
• Execute intrafamily sales to IDGTs

When Rates Are Rising:

• Existing fixed-rate loans remain at original AFR
• Consider refinancing older high-rate loans
• Evaluate installment sale strategies carefully

Documentation Requirements: Always document family loans with:

• Promissory note with fixed repayment terms
• Appropriate interest rate (at or above AFR)
• Security/collateral if applicable
• Actual repayment schedule followed

H2: Tax Forms and Reporting

Form 709 — Gift Tax Return: Required when forgone interest on a below-market loan exceeds the annual gift tax exclusion ($18,000 for 2025). File by April 15 following the year of the gift.

Schedule B — Interest and Ordinary Dividends: Report imputed interest income here if the IRS imputes interest on a below-market loan.

Form 1040 — Other Income: Some below-market loan situations require reporting on Line 8z.

Documentation to Retain:

• Copy of promissory note
• Proof of AFR rate in effect when loan was made
• Records of all payments received
• Gift tax returns filed (if applicable)

State Tax Note: Some states follow federal AFR rules; others have their own minimum rates. California generally conforms to federal AFR but check with a CPA for state-specific requirements.
