Structuring Family Loans to Transfer Wealth with Interest

Why family loans are used for wealth transfer

Family loans are a practical tool for moving value between generations without making outright gifts. They let a relative give favorable financing—often below market rates—while maintaining legal claim to repayment and earning interest income. When documented and priced correctly, a family loan can reduce the lender’s taxable estate, provide liquidity to the borrower, and avoid gift‑tax reporting pitfalls.

In my practice working with multi‑generational families, the most successful intra‑family loan strategies combine a clear legal agreement, adherence to the IRS’s Applicable Federal Rate (AFR) or a higher market rate, and regular repayments. Those elements preserve tax benefits and reduce family friction.

Key tax rules to know (plain English)

• Applicable Federal Rate (AFR): The IRS publishes monthly AFRs that set minimum interest rates for related‑party loans to avoid deemed gifts or imputed interest. Use the AFR as a floor for long‑term planning.
• Imputed interest (IRC section 7872): If you make a below‑market loan (including a zero‑interest loan), the IRS may treat some of the foregone interest as a gift or taxable income to the lender.
• Gift tax reporting (Form 709): If the loan terms or forgiveness cause the IRS to view part of the transfer as a gift (for example, if payments are not expected or interest is below AFR), the lender or borrower may need to file Form 709.
• Interest income and deductions: Lenders must report received interest as taxable income. Borrowers may have limited deductibility depending on use of funds (e.g., home mortgage interest rules).

Check current AFR figures and gift‑tax thresholds before documenting a loan—these change periodically (IRS AFR page).

Step‑by‑step checklist to structure a compliant family loan

1. Decide the purpose and amount

• Be explicit: home purchase, business seed capital, education, or help with medical bills. Document why the loan is made.

1. Choose a realistic interest rate

• Use at least the AFR for the appropriate term (short, mid, long). Charging at or above the AFR avoids imputed interest and gift treatment.

1. Draft a promissory note

• Include: names, principal, interest rate (APR), payment schedule, amortization method, maturity date, prepayment penalties (if any), remedy for default, and whether the loan is secured.

1. Set a repayment schedule and follow it

• Create an amortization schedule and move payments through bank transfers so there is an audit trail. Irregular or nonexistent payments increase the chance the IRS treats the transfer as a gift.

1. Consider collateral or security

• When appropriate, secure the loan with a mortgage or lien to document bona fide debt and reduce family conflict.

1. Document communications and intent

• Keep emails, meeting notes, and loan applications that show the transaction was intended as a loan, not a gift.

1. Evaluate gift tax implications

• If you plan to forgive payments or reduce principal outright, determine whether the forgiven portion will require Form 709 or use of the annual exclusion/lifetime exemption. See our guide to Gift Tax Basics: Annual Exclusion, Lifetime Exemption, and Reporting.

1. Consult professionals

• Use an estate attorney for legal language and a tax advisor for reporting. In many cases, an accountant will prepare a realistic amortization schedule and explain tax reporting for interest income.

Promissory note essentials (practical language to include)

• Borrower and lender full legal names and addresses
• Principal amount and date of loan
• Interest rate (annual) and how interest is calculated
• Repayment schedule: monthly/quarterly; show number of payments and amount
• Prepayment terms (can borrower prepay without penalty?)
• Security: collateral, deed of trust, or personal guarantee if appropriate
• Default remedies and cure period
• Governing law (state) and signatures with dates

A short, clear promissory note is often enough for small loans. For larger loans that affect estate plans, use an attorney to record deeds or file necessary liens.

Sample amortization examples

These examples show how repayments and interest work in real dollars (rounded):

• $50,000 at 3% for 10 years → monthly payment ≈ $483, total interest ≈ $7,946
• $100,000 at 5% for 15 years → monthly payment ≈ $790, total interest ≈ $35,400
• $20,000 at 2% for 5 years → monthly payment ≈ $440, total interest ≈ $2,388

These numbers illustrate why charging interest matters: the lender reports interest as income, while the borrower benefits from below‑market financing (if the rate is below commercial loan rates). Always calculate using the AFR if minimizing imputed gift risk is the goal.

Common strategies and variations

• AFR‑based loans: Lend at the published AFR (or slightly above) to avoid imputed interest. Useful for estate reduction without taxable gifts.
• Interest‑only with balloon: Borrower pays interest for a period and repays principal at maturity. Works when the borrower expects a liquidity event.
• Secured family mortgage: Parents deed a property to secure loan—formalizes debt and protects both parties.
• Loan plus partial annual forgiveness: Lender can forgive an agreed annual amount using the annual gift tax exclusion (check current limits) to reduce principal without breaching gift‑tax rules. See Lifetime Gifting Strategies to Reduce Estate Taxes for alternatives.
• Convert to sale: In some estate plans, an installment sale instead of a loan shifts assets and may give tax advantages—this requires precise valuation and legal work.

Pitfalls, risks and how to avoid them

1. No written agreement

• Result: high IRS scrutiny and family disputes. Always execute a promissory note.

1. Charging no interest or too low a rate

• Result: imputed interest rules can re‑classify part of the loan as a gift under IRC section 7872. To avoid this, use AFR minimums.

1. Not following repayment terms

• Result: missed payments can be considered constructive gifts.

1. Ignoring borrower tax outcomes

• Result: if debt is forgiven later, cancellation of debt rules may create taxable income for the borrower—plan any forgiveness with tax counsel.

1. Overreliance on informal promises

• Result: seller’s remorse, family conflict, and legal uncertainty. Formalize the arrangement.

When to consider alternate vehicles

• If you want to remove assets from your estate without expecting repayment, outright gifts or trusts (e.g., irrevocable trust) may be better. Compare pros and cons with Using Trusts vs Direct Gifts: Comparing Control, Taxes, and Flexibility.
• For business transfers, valuation discounts and buy‑sell structures often outperform simple loans—see our glossary on Valuation Discounts for Family Business Gifting.

Practical examples from practice

• Home purchase loan: I worked with parents who provided a $75,000 loan to their child at AFR + 0.5% with a 15‑year amortization. Monthly payments were made by bank transfer and the mortgage was recorded as a security interest. The arrangement reduced the parents’ estate while the child avoided higher mortgage insurance costs.
• Sibling business loan: A $100,000 loan at AFR for a sibling’s startup included a simple security agreement and scheduled annual reviews. When business cash flow tightened, the parties restructured—documented as an amendment—to avoid accidental forgiveness.

These deal structures preserved family relationships because terms were clear, payments were recorded, and both parties used legal counsel.

Action plan before you lend or borrow

1. Confirm current AFR and annual gift‑tax exclusion amounts (IRS website).
2. Decide whether the loan will be secured and what collateral is acceptable.
3. Draft a promissory note and amortization schedule; have both parties sign and retain copies.
4. Make and document payments through traceable channels (checks, bank transfers).
5. Consult a tax advisor about Form 709 reporting, interest reporting, and any possible estate‑tax impact.
