Real Estate in a Self-Directed IRA: Prohibited Transactions and UBIT

Holding real estate inside a self-directed IRA is legal, but the IRS rules for self-directed IRA real estate are strict enough that a single misstep can wipe out the account’s tax status. The property must be titled to the IRA and not to you, every dollar in and out has to move through the IRA’s own bank account, you and your close family cannot transact with the property or work on it, any mortgage must be non-recourse with no personal guarantee, and income tied to borrowed money is taxed at trust rates even inside a Roth. Break any of the prohibited transaction rules and the entire account is deemed distributed to you on January 1 of that year, taxable in full.¹

How the Property Must Be Held

A self-directed IRA still has to sit with a qualified trustee or custodian, the same as any other IRA.¹ The difference is that the custodian doesn’t advise you; it holds the assets, processes transactions, and files reports while you make the calls.

The deed matters. Title has to read in the custodian’s name for the benefit of your IRA, not in your personal name. That titling is what keeps the property inside the account’s tax-advantaged wrapper. If the deed shows you personally, the IRS treats the house as yours.

Some investors use a checkbook-control structure, where the IRA forms an LLC, funds it, and the LLC buys the property. You serve as the LLC’s uncompensated manager and can write checks for property expenses directly. The convenience is real, and so is the scrutiny: the Tax Court has treated IRA owners who exercised too much personal control over IRA assets — or took physical possession of them — as having received a taxable distribution. If you go this route, the operational rules below get more important, not less.

Prohibited Transactions and Who Counts as a Disqualified Person

The core compliance rule is Section 4975 of the tax code, which bans six categories of dealings between an IRA and any “disqualified person.”² Fair market value is not a defense. If the counterparty is disqualified, the transaction is prohibited regardless of terms.

The six prohibited categories:

Buying, selling, or leasing property between the IRA and a disqualified person. You cannot sell your own rental to your IRA, buy IRA property for yourself, or rent IRA-owned property to yourself or a family member.
Lending money or extending credit between the IRA and a disqualified person. This includes personally guaranteeing an IRA loan, even if the guarantee is never called on.
Furnishing goods, services, or facilities. You cannot repair the property, manage it for pay, or provide any service to it.
Transferring IRA assets to, or letting them be used by, a disqualified person. Staying in the property overnight, using it as an office, or letting a family member stay there is disqualifying.
A fiduciary using IRA income or assets for personal gain.
A fiduciary receiving personal consideration from anyone doing business with the IRA.

The disqualified-person list starts with you and the IRA’s fiduciary and extends to your spouse, parents, grandparents, children, grandchildren, and the spouses of your children and grandchildren.³ Siblings, aunts, uncles, and cousins are not on the family list, though they can still be disqualified through entity ownership.

Entities are disqualified when disqualified persons together own 50% or more of the value or voting power.² The ownership is aggregated. If you hold 30% of an LLC and your adult child holds 25%, the combined 55% makes the LLC a disqualified person even though neither of you individually crosses the threshold. Officers, directors, 10% shareholders, and 10% partners or joint venturers in an already-disqualified entity are themselves disqualified.

What a Violation Actually Costs

The penalty is not a fine. When an IRA owner or beneficiary engages in a prohibited transaction, the account ceases to be an IRA as of January 1 of that tax year, and the full fair market value of everything in it is treated as distributed to you on that date.¹ Ordinary income tax applies to the whole account, not just the piece of it tied to the violation.

If you are under 59½ when the account is disqualified, add the 10% early withdrawal penalty on top. For an IRA holding a $400,000 property and $50,000 in cash, a single misstep can drive the combined federal tax and penalty bill well into six figures.

Non-Recourse Loans and the Personal Guarantee Trap

An IRA is allowed to borrow to buy property, but only on a non-recourse basis. That means the lender’s only remedy on default is the property itself; your personal assets are off limits. Signing a personal guarantee turns the loan into a prohibited extension of credit from a disqualified person to the IRA. The Tax Court held in Peek v. Commissioner that two taxpayers lost the tax-exempt status of their Roth IRAs because they personally guaranteed and collateralized loans to their IRA-owned businesses.²

Non-recourse lenders exist, but they underwrite the property harder and typically want larger down payments than a conventional mortgage lender would.

UBIT on Debt-Financed Income

Borrowing changes the tax picture even when the loan is properly non-recourse. Rental income attributable to the borrowed portion of the property is Unrelated Debt-Financed Income and is taxed to the IRA under Unrelated Business Income Tax rules. Roth status does not shield you from this.

The taxable share is the average outstanding loan balance for the year divided by the property’s average adjusted basis for the year.⁴ An IRA that bought a $300,000 property with a $180,000 mortgage, and carried an average loan balance of $170,000 against an average adjusted basis of $290,000, would treat roughly 59% of net rental income as taxable. As the mortgage is paid down, that percentage shrinks.

The rate schedule is where this stings. UBIT on IRA income uses trust and estate brackets. For 2026, trust income reaches the 37% top bracket at roughly $16,000 of taxable income, so even a small amount of debt-financed rental income can be taxed at the top marginal rate.

The code allows a $1,000 specific deduction against unrelated business taxable income.⁵ Once UDFI clears $1,000 in a year, the IRA (or the checkbook LLC that holds the property) must file Form 990-T and pay the tax from IRA funds.⁶ Paying that bill personally would itself be a prohibited transaction.

UDFI also applies to capital gains on sale. The taxable share on sale is based on the average outstanding loan balance during the 12 months before closing. Investors who want to avoid UBIT on the gain sometimes pay the mortgage off at least a full year before selling; once the debt is retired and 12 months have passed, the debt-financed percentage drops to zero. That only works if the IRA has enough liquidity to retire the loan, which is a constraint when most of the account’s value sits in the building.

Day-to-Day Operating Rules

Treat the property as belonging to someone else, because legally it does. All rent goes into the IRA’s own account. Property taxes, insurance, repairs, and management fees all come out of that same account. Covering an emergency expense from your personal checking account, even a small plumbing bill, is commingling and can be treated as a prohibited transaction. Build a cash reserve into the IRA at acquisition so operating shortfalls never force the issue.

The ban on sweat equity is the rule investors resist most. You cannot mow, paint, patch a wall, or fix a faucet on IRA-owned property. Neither can your spouse, children, or any other disqualified person. Every task goes to unrelated third parties, paid from IRA funds. The IRS treats your labor as furnishing services to the IRA, which is prohibited.²

Recordkeeping is what keeps you out of trouble in an audit. Keep the purchase and sale documents, loan paperwork, every third-party invoice, and bank statements that show clean separation between IRA and personal funds. The burden of proving the IRA operated independently is yours.

Annual Valuation Reporting

Your custodian has to report the fair market value of the account’s assets each year on Form 5498, and real estate is flagged as a category requiring FMV reporting.⁷ Real estate has no daily market price, so an independent appraisal is required. Most custodians want one every year, and the fee (typically $500 to $800 for a single-family residential property) comes out of the IRA.

The FMV also drives the taxable amount whenever you take a distribution, do a Roth conversion, or satisfy an RMD. Understate the number and you underreport income; overstate it and you overpay. Either way the appraisal is your evidence if the IRS challenges the figure.

RMDs When Your IRA Owns a Building

Traditional SDIRA owners must begin required minimum distributions at age 73 under SECURE 2.0, with that age moving to 75 starting in 2033.⁸ Meeting an RMD from a stock IRA is trivial. Meeting one from an IRA whose main asset is a house is not.

There are three routes. You can take the RMD from cash inside the IRA, assuming you’ve built up rent proceeds or other liquid holdings. You can sell the property and distribute the proceeds, though the sale timeline rarely lines up with the RMD deadline. Or you can take an in-kind distribution of a fractional ownership interest in the property; the fraction distributed counts toward the RMD at its appraised value, but you end up co-owning the property with your IRA, which demands careful bookkeeping and ongoing valuations to avoid crossing into a prohibited transaction.

Missing an RMD triggers a 25% excise tax on the shortfall, reduced to 10% if corrected within two years. Plan for the RMD years ahead of age 73, not after. Roth IRAs have no lifetime RMD requirement, which is one of the strongest practical reasons to hold real estate in a Roth SDIRA rather than a traditional one.

Flipping and Dealer Status

Ordinary rental income inside an IRA is passive investment income, which is what IRAs exist to hold. Flip too often and the character changes. If the IRS or a court concludes the IRA is running a real estate business rather than investing passively, the profits become income from a trade or business subject to UBIT — no debt required.

There’s no bright-line count. The IRS and courts weigh why the property was acquired, how often the IRA buys and sells, and the scale of activity. One rental held for a decade looks nothing like three renovate-and-resell deals a year. The closer the pattern gets to a commercial operation, the greater the chance that sale proceeds get taxed as ordinary business income rather than passing through as excluded capital gains. If your strategy involves frequent sales, get a tax opinion before running it through an IRA.
