When loans are made between family members or within closely held businesses, certain tax rules must be followed to avoid unintended tax consequences. One of the most important considerations is ensuring that these loans meet the IRS's minimum interest rate requirements through the Applicable Federal Rate (AFR). This guide explains what the AFR is, when it must be used, and how to ensure your family or business loans are compliant with IRS rules.
The Applicable Federal Rate (AFR) is the minimum interest rate the IRS allows for private loans, including those between family members or within closely held businesses. The AFR changes monthly and is published by the IRS for three categories of loans based on their term:
Charging less than the AFR on a loan may result in the IRS treating the loan as a gift or as taxable compensation, which could lead to significant tax consequences for both the lender and borrower.
The AFR should be applied in a variety of scenarios, particularly when loans occur between family members or closely held businesses. Below are common situations where AFR is required:
When a family member loans money to another family member, whether to purchase a home, start a business, or cover personal expenses, the AFR must be charged to ensure the loan is legitimate. If the loan charges less than the AFR, the IRS may consider the difference as a gift, potentially triggering gift tax obligations.
Charging the AFR ensures the loan is recognized as a valid transaction, allowing the borrower to deduct mortgage interest (if applicable) and requiring the lender to report interest income.
In transactions where one family member or shareholder finances the sale of property to another, such as in intra-family real estate transfers, charging the AFR prevents the IRS from reclassifying the transaction as a gift. This also allows the buyer to deduct mortgage interest if the loan is secured by the property and meets IRS guidelines for home loans.
When a seller finances the sale of property through an installment sale, whether to a family member or closely held business, the AFR must be charged to avoid adverse tax treatment. Charging at least the AFR ensures the seller reports interest income correctly and the buyer can treat the payments as part of a legitimate loan agreement.
In closely held businesses, loans between the business and its shareholders must also adhere to the AFR. If the loan is made at below-market rates, the IRS may reclassify the loan as a dividend or compensation, leading to additional tax burdens. Charging at least the AFR protects both the lender and borrower from these reclassifications.
To comply with IRS rules, the lender must charge at least the AFR applicable to the loan’s term at the time the loan is made. Here’s how to ensure the loan is properly documented and compliant:
If a family or business loan is made without charging the AFR, the IRS may treat the loan as something other than a legitimate loan. This could lead to:
Charging at least the AFR is essential for ensuring that loans between family members and closely held businesses are treated as legitimate by the IRS. Whether you are lending to a family member, financing a property sale, or engaging in a loan with a closely held business, using the AFR protects both parties from potential tax complications and preserves important tax benefits.
