Self-Directed IRA Loans to Family: What the IRS Actually Allows

TL;DR

Your SDIRA can lend money to family members, but the IRS keeps a very specific list of relatives who are off-limits. Spouses, parents, children, grandchildren, and their spouses are all ‘disqualified persons’ under IRC Section 4975. Lending to any of them triggers a prohibited transaction that can wipe out your entire IRA tax status in a single year. Siblings, cousins, aunts, uncles, and nieces are not disqualified, so loans to those relatives are legal if you structure them correctly with a promissory note and a rate at or above the IRS Applicable Federal Rate. The penalties for getting this wrong are severe and irreversible, which makes understanding the exact line matter.

Self-directed IRA loans to family members are legal in some cases and flatly prohibited in others. The line is sharper than most investors expect. The IRS does not ban all family lending from your SDIRA. It bans lending to specific relatives it calls disqualified persons. If the family member you want to help falls into that category, there is no workaround inside the IRA. The transaction itself becomes illegal the moment it happens, and the consequences apply to your entire account, not just the loan amount.

The good news is that several family relationships are completely fine for SDIRA lending. If you want to help a sibling through a real estate deal, or lend to a cousin who’s starting a business, the IRS has no objection, provided the loan is structured at arm’s length with proper documentation. This guide walks through every distinction, the exact penalty math, and what you can do instead when the person you want to help is on the prohibited list.

Why the IRS Restricts SDIRA Loans to Certain Family Members

The logic behind the restriction is straightforward, even if the rules themselves get complicated. An IRA exists to build retirement savings, not to serve as a personal bank that benefits you and the people closest to you right now. Congress built the prohibited transaction rules into the tax code precisely to prevent IRA holders from routing money to themselves or their immediate families and calling it an ‘investment.’

The legal foundation is Internal Revenue Code Section 4975. That section defines which people and entities your IRA cannot transact with, and it sets the penalty structure for violations. The IRS reinforces this through its retirement plan guidance, which states clearly that self-dealing is one of the most common ways IRA holders unintentionally destroy their tax-advantaged status.

The core concept is arm’s-length dealing. Every transaction involving your SDIRA must be structured as if you had no personal relationship with the other party. When the other party is your spouse, child, or parent, genuine arm’s-length dealing is essentially impossible to prove, so the IRS does not allow it at all.

What Is a ‘Disqualified Person’ Under IRC Section 4975?

Section 4975 defines a disqualified person as any individual or entity that has a specific relationship to your IRA or to you as the IRA holder. The term covers a broader group than most people assume. It is not just your immediate household.

Disqualified persons for self-directed IRA lending purposes include:

• You, the IRA holder
• Your spouse
• Your parents and stepparents
• Your spouse’s parents and stepparents
• Your lineal ancestors (grandparents, great-grandparents)
• Your descendants: children, grandchildren, and great-grandchildren
• Adopted children and their spouses
• The spouses of your children and grandchildren
• Any fiduciary of the IRA plan
• Any entity in which you or a disqualified person owns 50% or more

The full statutory definition appears in IRS Publication 560 and the prohibited transactions guidance. The 50% ownership threshold for entities is one of the most frequently misunderstood parts of the rule. If your daughter owns 60% of an LLC, your SDIRA cannot lend money to that LLC either, even though you are lending to a business and not directly to her.

Which Family Members Can and Cannot Receive SDIRA Loans?

Here is the definitive breakdown. Keep this reference handy when evaluating any potential SDIRA lending arrangement with a family member.

PROHIBITED: Disqualified Family Members	ALLOWED: Family Members Who Can Receive SDIRA Loans
Spouse	Siblings (brothers, sisters)
Parents and stepparents	Siblings-in-law (spouse’s siblings)
Spouse’s parents and stepparents	Nieces and nephews
Children (biological, adopted, step)	Spouse’s nieces and nephews
Grandchildren and great-grandchildren	Aunts and uncles
Spouses of children and grandchildren	Spouse’s aunts and uncles
Lineal ancestors (grandparents, etc.)	Cousins of any degree
Entities owned 50%+ by the above	Friends, business partners, third parties

What About Stepchildren, In-Laws, and Other Gray Areas?

Stepchildren are a common source of confusion. The IRS treats stepchildren the same as biological children when it comes to prohibited transaction rules. If your stepchild is legally your dependent or you have adopted them, they are definitively disqualified. A stepchild you have not adopted formally still falls under most custodians’ interpretation of the rules as a disqualified person, because the spirit of the law covers relationships where you have a natural financial or personal interest.

Stepsiblings, on the other hand, are not specifically listed as disqualified persons in Section 4975. Loans to stepsiblings are likely permitted, but the structuring still needs to pass arm’s-length scrutiny. Consult a self-directed IRA attorney before executing any transaction involving step-relationships.

In-laws from your children’s marriages are disqualified. Your own siblings’ spouses (your brothers- or sisters-in-law) are not. That is a counterintuitive distinction that trips up a lot of investors.

What If a Family Member Owns Part of a Business Your SDIRA Wants to Lend To?

This is where the rules get expensive to misread. The 50% entity ownership threshold applies to the combined ownership of all disqualified persons, not each one individually. So if your spouse owns 30% of a company and your adult child owns 25%, that entity is disqualified from your SDIRA even though neither individual owner hits the 50% mark alone. The combined disqualified-person ownership is 55%, and that makes the entity off-limits.

The IRS FAQ on retirement plan prohibited transactions addresses entity ownership in detail. If you are structuring any loan through an LLC or partnership that involves family members, get a full ownership analysis done before directing your custodian.

What Actually Happens If You Loan SDIRA Funds to a Disqualified Family Member?

The penalties are not proportional to the size of the mistake. They are disproportionately severe, and that severity is intentional. The IRS designed the punishment structure to function as a total deterrent.

The Two-Level Penalty Structure Under IRC Section 4975

A prohibited transaction between your SDIRA and a disqualified person triggers two separate consequences:

First, your IRA loses its tax-exempt status as of January 1st of the year in which the prohibited transaction occurred. The entire account balance is treated as distributed to you on that date. You owe ordinary income tax on every dollar, regardless of whether you actually withdrew anything.

Second, if you are under age 59.5, you owe an additional 10% early withdrawal penalty on the entire account balance. This penalty applies to the whole IRA, not just the loan amount.

Third, the IRS can impose a 15% additional excise tax on the amount directly involved in the prohibited transaction under Section 4975(a). If the violation is not corrected, a 100% excise tax can apply. This is separate from the IRA disqualification.

You can review the full penalty structure in IRS Publication 590-B, which governs distributions from IRAs. The consequences apply to traditional and Roth SDIRAs alike, though the specific tax exposure differs based on account type.

What a Prohibited Transaction Costs in Real Dollars: A Concrete Example

A client came to us after realizing she had directed her SDIRA custodian to fund a short-term loan to her son’s real estate LLC. She was 54 at the time. Her SDIRA balance at the time of the transaction was $285,000. The loan itself was $40,000. Here is what the prohibited transaction cost her:

• Entire $285,000 treated as a taxable distribution
• Income tax at her marginal rate of 32%: approximately $91,200
• 10% early withdrawal penalty on $285,000: $28,500
• 15% excise tax on the $40,000 loan amount: $6,000
• Total tax damage: approximately $125,700, from one $40,000 loan

She did not lose the money in the loan itself. She lost the tax-protected status of her entire retirement account because of a transaction involving her son’s company. This outcome is not rare. It is exactly what the statutory language produces.

“Most prohibited transaction mistakes happen because investors don’t realize the entire IRA is at risk, not just the amount involved in the bad transaction. A $50,000 loan to a disqualified person can detonate a $400,000 IRA overnight. The asymmetry between the error and the consequence is what makes due diligence non-negotiable.”

How to Legally Structure SDIRA Loans to Allowed Family Members

If the family member you want to help is a sibling, cousin, aunt, uncle, niece, or nephew, your SDIRA can legally lend them money. The fact that it’s legal does not mean it’s automatic. You still need to structure the loan correctly, or you risk creating a different type of compliance problem.

What Documents Do You Need for a Legal SDIRA Family Loan?

Every SDIRA loan, whether to family or not, must be formalized with a promissory note. This is a legally binding agreement signed by the borrower that specifies:

1. The exact loan amount
2. The interest rate
3. The repayment schedule: monthly, quarterly, balloon, or other structure
4. The maturity date
5. Collateral, if any, and the lien or security agreement
6. Default provisions and remedies
7. Payment instructions directing funds to the SDIRA, not to you personally

The promissory note must be in the name of the IRA, not your personal name. Payments go back to the IRA. Interest income flows back to the IRA. Every dollar stays inside the tax-advantaged wrapper, which is the entire point of lending through an SDIRA rather than personal funds.

What Interest Rate Does Your SDIRA Have to Charge? (AFR Rules)

This is a detail almost nobody covers, and it’s one of the most important compliance requirements for private lending. When your SDIRA loans money to any borrower, the interest rate must reflect genuine market terms. For family members in particular, the IRS will scrutinize below-market rates as potential evidence of self-dealing, even if the borrower is technically not disqualified.

The safe harbor is lending at or above the IRS Applicable Federal Rate (AFR), which is the minimum interest rate the IRS considers arm’s-length for private loans. The AFR is published monthly by the Treasury and varies by loan term: short-term (3 years or less), mid-term (3 to 9 years), and long-term (over 9 years). Lending below the AFR to any borrower risks reclassification of the below-market portion as a gift or distribution from the IRA, which creates its own tax exposure.

Charging a rate above the AFR and in line with what a commercial lender would charge for similar collateral is the cleanest approach. For a real estate-backed loan to a sibling, that typically means a rate somewhere between the current AFR and hard money lending rates, depending on the borrower’s creditworthiness and the collateral quality.

“When we review SDIRA private loans to family members, the interest rate is the first thing we examine. A below-market rate to a cousin might look benign on the surface, but it signals that the loan may not have been structured truly at arm’s length. The IRS can use that as a foothold to question the entire transaction.”

What Are Your Options If You Want to Help a Disqualified Family Member?

The prohibited transaction rules close the SDIRA door for your spouse, children, and parents. But there are legitimate alternatives that don’t put your retirement account at risk.

The 60-Day Rollover Rule: A Short-Term Option With Serious Limitations

The IRS allows you to withdraw funds from your IRA and redeposit them within 60 days without triggering a distribution or tax. During those 60 days, you technically have the money in hand. Some investors use this to provide a very short-term bridge to a family member who will repay them before the 60 days expire.

Before you attempt this, read the full rules in IRS guidance on rollovers and IRA distributions. The critical limitations: you can only use the 60-day rollover once per 12-month period across all your IRAs. If the family member does not repay you in full within 60 days, the entire withdrawn amount becomes a taxable distribution. That’s not a risk you want to take with someone whose finances are already under pressure.

Name Them as a Beneficiary of Your SDIRA

If your goal is building generational wealth for a child or grandchild, naming them as a beneficiary to your SDIRA achieves that without any prohibited transaction risk. They inherit the account at your death and receive the tax-advantaged assets directly. For precious metals and alternative assets held inside a self-directed IRA, this can transfer substantial wealth with significant tax efficiency depending on account type.

Open a Custodial Roth SDIRA for a Minor Child

If your child has earned income, you can open a custodial self-directed Roth IRA in their name and contribute up to their earned income annually (subject to the annual IRA contribution limit). You fund the contributions from personal funds, not from your own IRA. The child gets decades of tax-free compounding. For 2026, the contribution limit is $7,000 for those under 50, or up to the child’s total earned income for the year if that amount is lower.

Use Personal Funds, Not IRA Funds

The cleanest alternative for helping a disqualified family member is simply using money from outside the IRA. Personal funds used for a family loan or gift do not put your SDIRA at any risk. Gifts up to the annual exclusion amount per recipient do not trigger gift tax reporting. Larger gifts require a gift tax return but typically do not result in actual tax until lifetime exemption limits are exceeded. A CPA can walk you through the gift tax implications specific to your situation.

“Investors get so focused on the IRA as a tool that they sometimes forget it’s only one vehicle. If helping a son or daughter with a down payment matters to you, the answer might simply be a personal gift or family loan structured outside the IRA entirely. Protecting the tax-advantaged status of the retirement account often creates more long-term family wealth than the specific transaction people are trying to force through it.”
 Marcus Reid, CFP, Retirement Portfolio Strategist

How SDIRA Private Lending Works When the Borrower Is Not Disqualified

When you’re lending to a non-disqualified person, whether that’s a sibling, a business partner, a real estate investor you know through your network, or a complete stranger, your self-directed IRA functions as a private lender. This is one of the most powerful features of the SDIRA structure, and it’s a major reason why investors use self-directed IRAs for alternative assets like private credit, real estate notes, and bridge lending.

What Types of SDIRA Loans Are Possible?

The asset types your SDIRA can hold as a lender include:

• Real estate-backed promissory notes secured by a first or second deed of trust
• Unsecured promissory notes (higher risk, typically higher rate)
• Hard money loans for fix-and-flip real estate investors
• Bridge loans for short-term project financing
• Business loans to qualifying entities
• Equipment financing secured by UCC filing
• Peer-to-peer loan participations

All loan income, including interest and any fees your IRA charges, flows back into the IRA tax-deferred (traditional) or tax-free (Roth). That compounding on interest income, without annual income tax drag, is the core financial advantage of SDIRA private lending over doing the same loans personally.

For a precise overview of the types of transactions your SDIRA can and cannot engage in, IRS Publication 590-A covers IRA contribution rules and structure, while the prohibited transactions rules from 26 U.S.C. Section 4975 via Cornell Law School provide the statutory text if you want to read the code directly.

How Private Lending Fits Into a Broader Self-Directed IRA Rollover Strategy

Most investors arrive at self-directed IRA private lending the same way: they roll a 401k or traditional IRA into a self-directed account, discover the range of alternative investments available, and begin looking for higher-yield options than publicly traded stocks and bonds can offer.

Private lending inside an SDIRA typically generates 8-14% annual returns on real estate-backed notes, compared to 4-5% on bonds or 1-2% on savings instruments. Over a 15-year horizon, that yield differential compounding inside a tax-advantaged wrapper creates substantial differences in retirement wealth. The family lending rules matter in this context because investors often want to lend to people they know and trust before expanding to outside borrowers.

The strategic move is to start with compliant loans to non-disqualified family members (siblings, cousins) or close associates, build the operational process for managing private notes inside an SDIRA, and then expand to third-party borrowers as you become more comfortable with due diligence and documentation. Rolling your existing 401k or traditional IRA into a self-directed account is the prerequisite for all of it.

If you are considering moving retirement funds into an SDIRA to access private lending, precious metals, real estate, or other alternative assets, the first step is understanding how a rollover works without triggering taxes or penalties. That process is straightforward when done correctly. We cover the full rollover mechanics in our self-directed IRA rollover guide.

KEY TAKEAWAYS

• Spouses, children, parents, grandchildren, and their spouses are disqualified persons. Your SDIRA cannot loan them money under any structure inside the IRA.
• Siblings, cousins, aunts, uncles, and nieces are not disqualified. SDIRA loans to these family members are legal when structured correctly.
• The penalty for a prohibited transaction is not proportional to the loan. Your entire IRA loses its tax status, retroactive to January 1st of that year.
• A 10% early withdrawal penalty applies to the entire account if you are under 59.5. A 15% excise tax applies to the loan amount. These stack on top of income taxes.
• All legal SDIRA loans must be documented with a properly executed promissory note and must use interest rates at or above the IRS Applicable Federal Rate.
• If a disqualified family member owns 50% or more of a business (combined with other disqualified persons), your SDIRA cannot lend to that business either.
• Legal alternatives for helping disqualified family members include naming them as beneficiaries, opening a custodial Roth IRA for a minor child, or using personal funds.
• Rolling an existing 401k or traditional IRA into a self-directed account is the prerequisite for SDIRA private lending. The rollover itself has no tax consequences when done correctly.
