Promissory Note
Formally document a loan between two parties with clear repayment terms.
A promissory note is a powerful financial instrument that transforms an informal loan into a legally enforceable debt obligation. Whether you're lending money to a family member, financing a business transaction, or structuring a seller-financed real estate deal, a properly drafted promissory note protects both the lender and borrower by creating clear expectations, defined repayment terms, and legal remedies if the borrower defaults.
Unlike casual IOUs or handshake agreements, promissory notes are formal legal contracts that can be enforced in court, sold to third parties, and used as evidence of debt in bankruptcy proceedings. They're essential for tax purposes, particularly when the IRS requires documentation of loans versus gifts between family members. For lenders, promissory notes provide a legal path to recover funds if borrowers don't pay. For borrowers, they prevent misunderstandings about repayment terms and protect against lenders changing the deal after funds are transferred.
What Is a Promissory Note?
A promissory note is a written, legally binding promise from one party (the borrower or maker) to pay a specific sum of money to another party (the lender or payee). It functions as both a contract and a negotiable instrument, documenting the principal amount borrowed, interest rate (if any), repayment schedule, maturity date, late payment penalties, and consequences of default. Promissory notes are more formal than IOUs but simpler than comprehensive loan agreements. They create enforceable debt obligations that can be used as evidence in court if the borrower fails to repay.
Types of Promissory Notes
Secured Promissory Note
The borrower pledges specific collateral—such as a vehicle, real estate, equipment, or securities—that the lender can seize and sell if the borrower defaults. Secured notes offer significantly more protection for lenders, often allowing for lower interest rates since the risk is reduced. The note must specify the collateral clearly and reference the corresponding security agreement. In real estate transactions, secured promissory notes are accompanied by mortgages or deeds of trust.
Unsecured Promissory Note
Not backed by any collateral—the lender relies solely on the borrower's creditworthiness and promise to repay. If the borrower defaults, the lender must sue and obtain a judgment before attempting to collect, which can be time-consuming and expensive. Unsecured notes are common for personal loans between family members and friends, small business loans, and educational loans. They typically carry higher interest rates to compensate for increased risk.
Demand Promissory Note
Repayment can be demanded by the lender at any time, with reasonable notice (typically 30 days). These notes don't have fixed maturity dates, making them flexible for short-term lending situations. However, borrowers face uncertainty about when they'll need to repay the full amount, and lenders must provide proper demand notice before claiming default.
Installment Promissory Note
The loan is repaid through regular periodic payments (monthly, quarterly, annually) until the balance is fully paid. Each payment typically includes both principal and interest. These are the most common type for personal loans, business financing, and seller-financed property sales. An amortization schedule can be attached showing how each payment is allocated between principal and interest.
What's the Difference Between a Promissory Note and a Loan Agreement?
A promissory note is a one-way promise from the borrower to repay the lender. It's signed only by the borrower and contains essential loan terms. A loan agreement is a two-way contract signed by both parties that includes detailed terms like representations and warranties, borrower covenants, lender obligations, and conditions precedent. Loan agreements are typically longer and more comprehensive. For simple personal loans, a promissory note alone is often sufficient. For business loans, real estate financing, or large amounts, both documents are recommended—the loan agreement governs the overall relationship while the promissory note is the negotiable debt instrument that can be sold or transferred.
Essential Terms to Include
A legally enforceable promissory note must contain specific elements. Missing key provisions can make the note unenforceable or create ambiguity that leads to disputes:
Principal Amount
The exact amount being borrowed, written in both numbers and words (e.g., "$10,000.00 (ten thousand dollars)"). If written amounts differ, the written words typically control.
Interest Rate
Specify whether interest is fixed or variable, the annual percentage rate (APR), and how often interest compounds (daily, monthly, annually). Be aware of state usury laws that cap maximum interest rates—exceeding them can void the entire note or subject you to penalties.
Payment Schedule
Detail when payments are due (e.g., "first day of each month"), the amount of each payment, where payments should be sent, and what payment methods are acceptable (check, wire transfer, ACH). Include whether there's a grace period before late fees apply.
Maturity Date
The date when the final payment is due and the loan must be fully repaid. For balloon payment notes, most payments may be interest-only with the entire principal due at maturity.
Late Fees and Default Terms
Specify late payment penalties (typically $25-$50 or 5% of the payment), grace periods, and what constitutes default (usually missing 2-3 payments or breaching other terms). Include acceleration clauses allowing the lender to demand full immediate repayment upon default.
Prepayment Rights
State whether the borrower can repay early without penalty. Some commercial promissory notes include prepayment penalties to compensate lenders for lost interest income.
Do I Need to Charge Interest on a Promissory Note?
You're not legally required to charge interest, but there are important tax implications. The IRS imputes interest on below-market loans between family members above $10,000, treating the forgone interest as a taxable gift. For loans above $100,000, you must use the Applicable Federal Rate (AFR) or face tax consequences. Zero-interest notes are allowed for small loans under $10,000, but documenting the loan with a promissory note distinguishes it from a gift. For business loans or loans to non-family members, charging interest is standard practice. Most states have usury laws capping maximum interest rates—typically 6-10% for consumer loans and higher for commercial loans.
IRS Requirements and Tax Implications
The IRS closely scrutinizes loans between family members to ensure they're genuine loans and not disguised gifts. Without proper documentation, the IRS can reclassify your loan as a gift, triggering gift tax consequences.
To Prove Your Loan Is Legitimate:
- Execute a formal promissory note signed by the borrower
- Charge interest at or above the Applicable Federal Rate (updated monthly by the IRS)
- Set a definite repayment schedule with specific due dates
- Require the borrower to make regular payments (and actually enforce this)
- Keep detailed records of all payments received
- For secured loans, file a UCC-1 financing statement or mortgage to perfect your security interest
- If the borrower misses payments, send demand letters and take enforcement action
Tax Reporting: Lenders must report interest income on Schedule B of Form 1040. Borrowers cannot deduct interest on personal loans but may deduct interest on business or investment loans. If a loan becomes uncollectible, lenders may claim a non-business bad debt deduction on Schedule D as a short-term capital loss.
Is a Promissory Note Legally Binding?
Yes, a promissory note is a legally binding contract that can be enforced in court. To be enforceable, it must: (1) Be in writing (oral promises to repay are generally not enforceable under the Statute of Frauds), (2) Identify the borrower and lender, (3) State the principal amount, (4) Include an unconditional promise to pay, (5) Be signed by the borrower. While witnesses and notarization aren't required in most states, they add extra proof of authenticity and help prevent fraud claims. A properly executed promissory note gives lenders the right to sue for repayment, obtain judgments, garnish wages, place liens on property, and pursue other collection remedies if the borrower defaults.
What Happens If the Borrower Defaults?
When a borrower misses payments or otherwise defaults on a promissory note, lenders have several options depending on whether the note is secured or unsecured:
For Secured Notes
Lenders can seize and sell the collateral through repossession (for vehicles/equipment) or foreclosure (for real estate). The proceeds are applied to the outstanding debt. If the collateral sale doesn't cover the full amount owed, lenders can pursue a deficiency judgment for the remainder. Secured creditors have priority over unsecured creditors in bankruptcy proceedings.
For Unsecured Notes
Lenders must file a lawsuit, prove the debt is valid, and obtain a court judgment. Once a judgment is obtained, creditors can garnish wages (up to 25% in most states), place liens on property, levy bank accounts, and seize non-exempt assets. The collection process can take months or years and may cost thousands in legal fees.
Before pursuing litigation, most lenders send formal demand letters, attempt to negotiate payment plans, report missed payments to credit bureaus, or hire collection agencies. For family loans, consider whether preserving the relationship is worth more than recovering the debt.
Can a Promissory Note Be Transferred or Sold?
Yes, promissory notes are negotiable instruments that can be sold, transferred, or assigned to third parties—this is called "negotiation" or "assignment." The lender (payee) can endorse the note by signing it and transferring ownership to another person or entity. The new holder then has the right to collect payments and enforce the note. This is how mortgage lenders sell loans on the secondary market. For a note to be freely transferable, it should include the words "or order" after the payee's name (e.g., "pay to John Smith or order"). Notes can also be used as collateral for other loans. However, borrowers must be notified when their note is transferred so they know where to send payments.
