Family Loan Promissory Note
A family loan promissory note documents a loan between family members — parents, siblings, or other relatives — with the terms needed for IRS compliance and to protect the lender's ability to recover the funds if repayment is not made.
When to Use a Family Loan Note
Use when lending money to a family member to document the loan, establish repayment terms, and comply with IRS requirements (particularly the Applicable Federal Rate for loans over $10,000).
What Makes This Type Different
How a Family Loan Note differs from the standard Promissory Note.
- IRS Applicable Federal Rate compliance to avoid gift tax treatment
- Flexible repayment terms appropriate for family situations
- Simple default provisions that acknowledge the family relationship
- Can include forgiveness provisions for estate planning purposes
Complete Guide: Family Loan Promissory Note
A family loan promissory note is a formal written agreement between relatives—parents and children, siblings, grandparents and grandchildren, aunts and uncles and their nieces and nephews—documenting the terms of a monetary loan within the family. Family loans are common vehicles for helping relatives purchase their first home, start a business, pay for education, bridge a financial gap, or recover from a financial setback. While the desire to help family members is genuine and admirable, undocumented family loans are a leading cause of post-mortem estate disputes, sibling conflict, and family estrangement. A formally documented promissory note transforms a well-meaning gesture into a clear, legally enforceable agreement that protects everyone involved.
The distinction between a loan and a gift becomes legally and financially significant in multiple contexts. If a parent lends money to one child without documentation, other children may claim at the parent's death that the loan was actually a gift—or, conversely, that the loan should be repaid to the estate and treated as an advance on the borrowing child's inheritance. The IRS treats undocumented loans between family members with suspicion—if the transfer looks more like a gift than a loan (no repayment has occurred, no promissory note was signed, no interest was charged), the IRS may recharacterize it as a gift and assess gift tax if the cumulative gift amount exceeds the annual exclusion. A signed promissory note with a reasonable repayment schedule and interest rate is the primary evidence that a transfer was a genuine loan.
Family loan promissory notes serve a protective function for both the lender and the borrower. For the lender, the note creates a legally enforceable claim that can be pursued if the relationship sours, if the borrower becomes financially irresponsible, or if the lender needs to document the loan as an asset in their own estate. For the borrower, the note creates clarity about their obligation—they know exactly how much they owe, when payments are due, and what happens if they miss a payment—reducing anxiety about an undefined or open-ended family obligation. Clear documentation often preserves relationships better than informal arrangements that breed resentment and misunderstanding.
The interest rate on a family loan must meet IRS minimum requirements to avoid imputed interest treatment. The IRS publishes monthly Applicable Federal Rates (AFRs) at short-term, mid-term, and long-term maturities. Loans with terms of three years or less use the short-term AFR; loans of three to nine years use the mid-term AFR; loans of more than nine years use the long-term AFR. If the family loan charges interest at or above the applicable AFR, the IRS will not impute additional interest or treat the forgone interest as a gift. AFRs are relatively low compared to commercial lending rates, making them accessible while satisfying IRS requirements. For loans of $10,000 or less between family members, the imputed interest rules do not apply.
How to Create a Family Loan Note: Step-by-Step
- 1
Agree on Loan Amount, Term, and Interest Rate
Decide the principal amount, the loan term (how long the borrower has to repay), and the interest rate. Check the current IRS Applicable Federal Rate for the appropriate term (short, mid, or long-term) to ensure the rate meets minimum IRS requirements. The rate can be higher than the AFR if the lender wishes to charge a fair market rate, but cannot be zero or below the AFR for larger loans without triggering imputed interest consequences.
- 2
Calculate and Document the Repayment Schedule
Calculate the regular payment amount using the principal, interest rate, and term. For installment loans, prepare an amortization schedule showing each payment date, payment amount, interest component, principal component, and remaining balance. Attach the amortization schedule to the note as an exhibit. For lump-sum loans, state the single due date and the total amount due (principal plus any accrued interest). Both parties should understand and agree to the schedule before signing.
- 3
Address the Treatment of Loan Balance in the Lender's Estate
Consider how the outstanding loan balance will be treated in the lender's estate plan. Options include: the borrower repays the full balance before the lender's death; the lender's will forgives any outstanding balance as a specific bequest; the outstanding balance is counted as part of the borrower's inheritance share (an advancement); or the loan continues as an estate asset that the executor must collect. State the lender's intent in the note or in their estate planning documents to prevent ambiguity.
- 4
Include Default Provisions Appropriate for the Family Context
Default provisions in a family loan context are sensitive—the goal is clarity, not weaponization. Include a reasonable grace period for missed payments. For modest amounts, a demand for full repayment upon default may be disproportionate; consider a modified payment plan as the first remedy. State that the lender may pursue legal collection as a last resort, but also indicate a preference for communication and resolution before enforcement. The note should be firm enough to be enforceable but drafted with the family relationship in mind.
- 5
Execute and Maintain Records
Both parties should sign the note; the lender keeps the original and the borrower keeps a copy. Maintain records of every payment: amounts, dates, method, and running balance. Issue a receipt for each payment or maintain a shared spreadsheet. At year-end, calculate any interest paid (for the borrower's potential deduction if the loan is for a business or investment purpose) and any interest received by the lender (which is taxable income). This recordkeeping discipline demonstrates to the IRS that the loan is genuine.
Key Legal Considerations
Annual Gift Tax Exclusion and Forgiveness of Loan Balances
Each year, a lender may forgive up to the annual gift tax exclusion amount ($18,000 per recipient in 2024) of the outstanding loan principal without gift tax consequences. This allows a parent, for example, to forgive $18,000 of a $100,000 family loan each year, effectively reducing the obligation over time as a planned giving strategy. If the forgiveness exceeds the annual exclusion in any year, the excess reduces the lender's lifetime unified gift and estate tax exemption. Document each annual forgiveness in a written letter to maintain a clear record of the loan balance and the forgiveness history.
Medicaid Look-Back Period and Family Loans
When an elderly family member makes a loan to a younger relative—particularly if the lender might need nursing home care within five years—Medicaid's five-year look-back period is a critical consideration. Medicaid eligibility reviewers examine all financial transfers within the five years preceding the application for long-term care benefits. An undocumented transfer will be treated as a gift, creating a disqualification period. A properly documented promissory note with commercial terms (reasonable interest rate, fixed repayment schedule) may be treated as a legitimate loan rather than a gift transfer, preserving the lender's Medicaid eligibility. This area of law is complex and state-specific; consult an elder law attorney.
Estate Advancement and Equalization Among Heirs
When one child receives a family loan that another child does not, estate equalization issues arise at the lender's death. If the loan is outstanding at death and the estate plan does not address it, the estate must decide whether to call the loan (collect from the borrowing child) or forgive it—while other children receive full shares of the estate without the benefit the borrowing child received. A well-planned promissory note should coordinate with the lender's will: either requiring repayment to the estate (reducing the borrowing child's inheritance by the loan balance) or forgiving the balance through a specific will bequest that is charged against the borrowing child's share.
Bankruptcy Preference Period for Family Loan Repayments
If a family member borrower files for bankruptcy within one year of making repayments to a family lender, those repayments may be subject to recovery as "preferential transfers." A bankruptcy trustee can "claw back" payments made to family members (insider creditors) within the one-year period before bankruptcy, while the look-back period for non-insiders is only 90 days. This means that repayments made in good faith to a family lender may be demanded back by the bankruptcy trustee. Family lenders receiving repayments should be aware of this risk, particularly if the borrower is in financial distress.
Common Mistakes to Avoid
Setting a Below-AFR Interest Rate Without Understanding the Tax Consequences
Charging below the Applicable Federal Rate (or no interest at all) on a family loan above $10,000 triggers IRS imputed interest rules that treat the forgone interest as a gift from the lender to the borrower each year. This creates income for the lender (who must report the imputed interest even though they did not receive it) and a gift from the lender that counts against the annual exclusion. Check the current AFR and charge at least that rate to avoid these consequences.
Making Loan Payments Informally Without Records
Family loan payments made in cash without receipts, or as parts of larger transactions (mixed with birthday gifts or holiday transfers), are impossible to document accurately. The IRS may question whether payments were made at all, and estate beneficiaries may dispute the loan balance at the lender's death. Use bank transfers with memo lines identifying the payment, or write checks, and maintain a running payment log. Issue annual statements of the outstanding balance to the borrower.
Not Distinguishing the Loan from Other Financial Support
When parents provide both loans and gifts to a child simultaneously—paying for a wedding while also making a business loan—the lines blur. Keep the promissory note transactions strictly separate from gift-giving: different accounts, clear payment references, and distinct paperwork. Commingled records make it impossible to distinguish loan repayments from gift receipts, which creates both tax and estate administration problems.
Failing to Review the Note After Major Life Changes
A family loan promissory note signed when a borrower was financially stable may become unworkable if the borrower loses their job, divorces, or faces a medical crisis. Rather than allowing the note to default, proactively review and modify the terms: extend the repayment period, reduce payments temporarily, or restructure the balance. Document modifications in a written amendment signed by both parties.
Not Coordinating the Note with the Lender's Estate Plan
A promissory note that survives the lender's death becomes an estate asset that the executor must pursue—even within the family. If the lender intended to forgive the balance, that intent must be expressed in the will. If the lender intended the balance to reduce the borrower's inheritance share, the will must state this. Without coordination, the executor may be legally obligated to collect the loan against the lender's implicit forgiveness intentions.
