Intrafamily Loans: How to Act as the “Bank” for Your Heirs

By Team BMT Jan 10, 2026

💡 Executive Summary

  • Problem: Gifting money directly to children (e.g., for a house or business) consumes your Lifetime Estate Tax Exemption ($13M+).
  • Solution: Lend the money instead, charging the minimum IRS-mandated interest rate (AFR).
  • Result: Any investment growth above the interest rate (Hurdle Rate) passes to your heirs 100% Gift Tax-Free.
⚠️ THE “FORGIVENESS” TRAP
If you lend the money but never collect interest or eventually “forgive” the loan without a reason, the IRS reclassifies the entire amount as a Taxable Gift. You must act like a real bank (Promissory Note + Annual 1099-INT).

In the UHNW ecosystem (Tier L3+), “The Bank of Mom & Dad” is not a casual favor; it is a structured wealth transfer vehicle. By leveraging historically low AFRs, families can shift millions of dollars of upside to the next generation without touching their exemption.

🧐 Core Mechanic: The AFR Spread
If the IRS AFR is 4.0% and your child invests the loan proceeds in a business or real estate earning 10.0%, the 6.0% spread is wealth transferred completely free of gift/estate tax.

“Intrafamily loans teach financial responsibility. Heirs are not receiving a handout; they are receiving ‘access to capital’ on favorable terms. It changes the mindset from entitlement to stewardship.”
