When a family member comes to you asking for help—whether it’s your child needing money for a first home, a grandchild starting a business, or a sibling going through a rough patch—it’s only natural to want to lend a hand. Sometimes, that “hand” is financial support. But how do you do it in a way that’s generous, fair, and smart?
That’s where intrafamily loans come in. These are financial arrangements between relatives—where one family member lends money to another. While they might seem informal at first glance, these loans can be powerful financial tools when done right, offering benefits to both the lender and the borrower.
In this guide, we’ll explore what intrafamily loans are, how they work, and what you need to know to make sure they’re structured properly—legally, financially, and personally.
What Is an Intrafamily Loan?
An intrafamily loan is exactly what it sounds like—a loan made from one family member to another. But it’s more than just handing over cash and saying “pay me back when you can.” Done properly, it’s a legal agreement that includes a promissory note (a formal IOU), a repayment plan, and a stated interest rate.
These loans are often used to help family members:
- Buy a home or pay for a down payment
- Start or invest in a business
- Pay off high-interest credit card debt
- Cover college or grad school tuition
- Invest in stocks or real estate
- Refinance existing personal loans
For the lender, it’s an opportunity to support a loved one while earning interest, often at a better rate than a savings account or CD. For the borrower, it can mean more favorable terms and flexibility than they’d get from a bank—especially if they have limited credit or income.
When Does an Intrafamily Loan Make Sense?
Giving money to a loved one outright as a gift might seem easier. But depending on the amount, it could come with gift tax consequencesor create confusion about expectations. By contrast, a loan:
- Preserves your estate while helping your family
- Keeps you in control of the money you’re lending
- Maintains clear boundaries and expectations for repayment
- Can help the borrower build credit and learn financial responsibility
- May be part of a strategic estate plan to transfer wealth tax-efficiently
If you’re looking for a way to support someone financially without permanently giving away your assets, an intrafamily loan might be the perfect middle ground.
A Smart Tool for Estate Planning
One of the biggest reasons people consider intrafamily loans is for estate planning. With the current federal estate and gift tax exemption sitting at $13.61 million per individual (or $27.22 million for married couples in 2024), high-net-worth families are looking for ways to transfer wealth without triggering unnecessary taxes.
Here’s how a properly structured intrafamily loan can help:
- Let’s say you loan $300,000 to your child at a low but IRS-approved interest rate.
- They invest that money and earn a 10% return over several years.
- As long as the return exceeds the interest you’re charging, the excess growth stays with them, not in your estate.
- Meanwhile, your loan remains a recoverable asset, and the interest you receive can even generate investment income for you.
You can also loan money to a trust instead of an individual. This adds a layer of control and protection and can be ideal for minor children or heirs with special needs.
The Importance of Charging Interest (and How the IRS Comes In)
It might feel strange to charge interest to your child or grandchild—but here’s why it’s important.
The IRS has rules in place to prevent people from avoiding gift taxes by disguising gifts as loans. So, if you lend money and don’t charge enough interest, the IRS may “impute” interest income—that means they’ll pretend you received interest and tax you on it, even if you didn’t collect a dime.
To avoid this, your loan needs to charge at least the Applicable Federal Rate (AFR), which is published monthly by the IRS. There are three categories:
- Short-term: Loans under 3 years
- Mid-term: 3 to 9 years
- Long-term: Over 9 years
These rates are typically lower than what commercial lenders charge, which is part of what makes intrafamily loans appealing. You can even fix the interest rate for the entire life of the loan based on the AFR when you issue it—potentially locking in a lower cost even if rates rise later.
How to Structure the Loan Properly
To protect yourself and your loved one—and avoid headaches later—you’ll want to formalize the loan. This means:
1. Write a Promissory Note
This is the heart of the loan agreement. It should clearly state:
- The amount being borrowed
- The interest rate
- The repayment schedule (monthly, annually, balloon payment, etc.)
- The loan term (how long the borrower has to repay)
- Any provisions for default (missed payments)
- Whether the loan will be forgiven or called due at your death
You may also want to outline whether the borrower can prepay the loan early, and if so, whether there are any penalties.
2. Keep Good Records
Even if it’s family, you need to keep accurate records. Document all payments received, and consider having a third party—like an accountant or bookkeeper—track the loan over time. This is especially helpful if you pass away before the loan is paid back.
3. Consider Collateral (When Appropriate)
In most cases, intrafamily loans are unsecured, meaning there’s no collateral (like a house or car) backing them. But in larger loans—especially for real estate—you may want to secure the loan with a lien, just like a bank would. This adds a layer of protection for the lender and can make the agreement feel more official.
Key Questions to Ask Before You Lend to Family
Every family is unique, and every loan comes with both financial and emotional dynamics. Before moving forward, it’s worth asking:
- Will helping one child cause resentment among others?
If you’re only lending to one family member, consider how that decision may be perceived by others. Should you make similar arrangements for your other children? - What happens if they can’t repay the loan?
Will you forgive it? Call it due? Take legal action? These are hard questions, but they’re better addressed now than in a crisis. - Should the loan be deducted from their inheritance later?
Some parents choose to offset loans against future inheritances. For example, if a child borrowed $50,000 and your estate is being divided equally, their share might be reduced accordingly. - Will this loan affect my retirement or estate goals?
Make sure you’re not putting your own financial security at risk—especially if the borrower can’t repay on time.
When to Consider Gifting Instead
Sometimes, it might make more sense to simply give the money rather than lend it. Under current laws, you can give up to $18,000 per person (or $36,000 for couples) in 2024 without using your lifetime gift tax exemption or filing a gift tax return.
If the amount is modest and you don’t expect repayment—or if charging interest would create a burden—it might be better to treat the money as a gift. Just be sure to document it as such and consult a tax advisor if needed.
Don’t Forget to Include It in Your Estate Plan
If you have an active intrafamily loan, it should be included in your estate planning documents. This ensures your executor or trustee knows how to handle it if you pass away before it’s repaid.
Some things to consider:
- Should the loan be forgiven upon your death?
- Or should it remain an asset of the estate, to be repaid to your heirs or trust?
- Will interest still accrue after your passing?
Your estate attorney can help you craft language that fits your wishes and avoids confusion or conflict among family members.
Final Thoughts: Lending with Love—and Wisdom
At the end of the day, intrafamily loans are more than financial transactions—they’re about trust, care, and family support. When approached thoughtfully and documented properly, they can be a beautiful way to empower loved ones while still protecting your financial legacy.
But like any financial decision, it’s important to look at the big picture. Consider the tax implications, the legal responsibilities, and—just as important—the emotional impact on your family relationships.
Before moving forward, talk with an estate planning attorney, tax professional, or financial advisor. With the right guidance, an intrafamily loan can be one of the most rewarding tools in your wealth planning toolkit.
