Short answer: no, not from a traditional or Roth IRA, if the family member is your spouse, parent, grandparent, child, or grandchild. The IRS treats that as a prohibited transaction, and the penalty is not a fine on the loan. It can disqualify your entire IRA. There is a narrower exception for siblings, nieces, nephews, aunts, and uncles, and a completely different path through a 401(k) that many people confuse with the IRA rule. Both deserve a closer look before you touch retirement money to help a relative.
This matters because family loans and retirement accounts collide more often than people expect: a parent wants to help a child with a down payment, a sibling needs $15,000 for a business, and the biggest pile of cash in the house happens to sit inside an IRA or a 401(k). The rules for touching that money are stricter, and stranger, than most people assume. For the wider tax picture beyond retirement accounts, our family loan tax guide covers what the IRS expects from any intra-family loan.
What Counts as "Family" Under the IRA Rules
The IRS calls certain people "disqualified persons" for IRA purposes, and the definition is narrower than most families expect. Under IRS guidance on prohibited transactions, disqualified persons include the IRA owner, the owner's fiduciary, and family members defined specifically as a spouse, ancestor, lineal descendant, and any spouse of a lineal descendant.
In plain terms, that means:
- Disqualified (loan is prohibited): spouse, parents, grandparents, children, grandchildren, and the spouses of your children or grandchildren.
- Not disqualified (no prohibited-transaction rule against them): siblings, nieces, nephews, aunts, uncles, and cousins.
That second list surprises people. The IRS prohibited-transaction rule is about specific blood and marriage lines going straight up or down your family tree, not about "family" in the everyday sense.
What Happens If You Lend IRA Money to a Disqualified Person
If you lend money directly from your IRA to your spouse or an adult child, you have engaged in a prohibited transaction as the IRA owner. The consequence is not a penalty on the loan itself. Under IRC Section 408(e)(2), your account stops being an IRA as of January 1 of that year. The entire balance, not just the amount you lent, is treated as distributed to you at fair market value and becomes taxable income. If you are under 59 1/2, add the standard 10% early-withdrawal penalty on top.
A separate excise tax applies to the disqualified person who received the benefit, if that person is not the IRA owner. The IRS describes an initial tax of 15% of the amount involved for each year the transaction remains uncorrected, rising to 100% of the amount involved if it is not corrected within the taxable period.
Picture a $50,000 IRA lending $20,000 to an adult daughter for a home down payment. The parent does not just risk 15% of the $20,000. The full $50,000 account loses its tax shelter, becomes a taxable distribution in the year of the loan, and (if the parent is 55) triggers a 10% early-withdrawal penalty on top of ordinary income tax on the whole balance. A well-meant $20,000 favor can produce a five-figure tax bill.
The Sibling Exception Is Real, but Rarely Usable
Because siblings, nieces, nephews, aunts, uncles, and cousins are not disqualified persons, lending IRA money to a brother or sister does not trigger the prohibited-transaction rule described above. That is a genuine gap in the statute, not a myth.
In practice, three things narrow it fast:
- Custodians will not administer it. A standard IRA at a brokerage does not offer a "make a personal loan" feature. You would need a self-directed IRA with a custodian willing to hold a promissory note as an IRA asset, and most mainstream custodians decline private-loan assets entirely.
- The loan still has to look like a real loan. The note needs a market interest rate, a fixed repayment schedule, and genuine collateral or creditworthiness review. An IRA that lends to a struggling sibling at 0% or with no realistic repayment plan can still be challenged as a transaction that does not serve the plan's exclusive purpose of benefiting the account owner's retirement.
- Your retirement money is now credit risk. If your sibling misses payments, you are not chasing a $15,000 favor. You are watching a piece of your retirement account default, with no FDIC or SIPC protection behind it.
The sibling exception is worth knowing so you do not panic over a loan that is not actually prohibited. It is rarely worth using, because the compliance overhead and the risk to your retirement savings usually outweigh what you would gain over simply lending the same amount from a regular savings account.
The 401(k) Alternative: Borrow From Yourself, Then Lend the Cash
A 401(k) works differently from an IRA, and this is where people get the two rules mixed up. Under IRS plan-loan rules, a participant can generally borrow up to 50% of their vested balance, capped at $50,000 (with a $10,000 minimum-balance exception), repayable over five years with at least quarterly payments.
Nothing in the IRS rules restricts what you do with that cash once it lands in your bank account. A 401(k) loan is a loan to you, the participant, not to your IRA. Once it is disbursed, it is ordinary money. You could use it for a kitchen remodel, and you can just as legally hand it to your daughter to help with a car or turn around and lend it to your brother for a business.
That is not a loophole in the sense of exploiting a gap. It is simply a different, permitted transaction: the plan lends to you, and separately, you lend to your relative. The two loans are legally independent, which is exactly why the risk below matters.
The Risk Nobody Mentions: You Can Lose the Money Twice
Consider an $80,000 vested 401(k) balance. The plan allows a loan up to 50%, or $40,000. You borrow the full $40,000 and lend it to your son for a down payment, structured as a real family loan with a signed promissory note and interest at the Applicable Federal Rate.
Eighteen months later, you are laid off. Under the rule that followed the 2017 Tax Cuts and Jobs Act, you now have until your federal tax return due date, including extensions, for that year to roll the outstanding loan offset into an IRA using outside cash. If you cannot come up with $40,000 in that window because it is tied up in your son's repayment schedule, the unpaid balance becomes a taxable distribution, plus the 10% early-withdrawal penalty if you are under 59 1/2.
You are now exposed twice on the same $40,000: once as the borrower who owes the plan, and once as the lender waiting on your son. If both go wrong at the same time, which is exactly when job loss and family financial stress tend to cluster, you can lose the retirement tax shelter and still be short the money your son owes you.
A Cleaner Way to Use Retirement Savings to Help Family
If you are over 59 1/2 and simply want to use retirement savings to fund a family loan, a standard distribution avoids both traps above. You pay ordinary income tax on the amount withdrawn (no early-withdrawal penalty at that age), the cash is unambiguously yours, and you can lend it to any relative, including a spouse or child, without touching the prohibited-transaction rule at all. The tradeoff is that you accelerate tax on money that would otherwise keep growing tax-deferred, so it is worth comparing that cost against the interest you would collect.
| Path | Who you can lend to | Main risk | Best fit |
|---|---|---|---|
| Direct IRA loan to family | Legally, only non-disqualified relatives (siblings, nieces, nephews, etc.) | Prohibited-transaction rule if you get the relationship wrong; custodians rarely allow it | Almost nobody; too much compliance risk for the benefit |
| 401(k) participant loan, then personal loan to family | Anyone, since it is your money once disbursed | You owe the plan on its schedule regardless of whether your relative repays you; job loss shortens your window | Only if you can independently cover the 401(k) repayment even if the family loan fails |
| Standard withdrawal after 59 1/2, then personal loan | Anyone | Income tax due immediately on the withdrawal; opportunity cost of leaving tax-deferred growth | Retirees or near-retirees who want a clean, simple structure |
Whichever path funds the loan, treat what happens next like any other family loan: put it in writing, and set a real interest rate at or above the current Applicable Federal Rate to avoid imputed-interest problems. Keep a payment record too. If the loan later goes unpaid, claiming it as a bad-debt tax deduction has its own strict paper-trail requirements, and a clean record is what makes that possible. Our loan agreement generator builds that paperwork in a few minutes, and Family Loan Tracker keeps the payment history so you are not reconstructing it from memory two years later.
This is not tax or legal advice. Retirement-account rules carry real penalties for getting the details wrong, so confirm your specific situation with a tax professional or an ERISA attorney before you move money out of an IRA or 401(k) to fund a loan to a relative.
