UBIT and UBTI in an IRA: When Alternative Assets Create a Tax Bill

An IRA is a tax exempt account, but not completely. If it earns business income or uses debt, the retirement account itself can owe unrelated business income tax (UBIT). The IRA pays the tax, not you, and it applies to traditional and Roth IRAs alike.

Investments in publicly traded stocks and bonds generally don’t trigger it. Self directed IRA investments in real estate, partnerships, and private businesses can. This guide explains what triggers it, how it’s calculated, and when the IRA must file Form 990-T.

What does UBIT stand for?

UBIT stands for unrelated business income tax (UBIT). UBTI stands for unrelated business taxable income (UBTI), the amount the tax is imposed on.

Section 408(e)(1) of the internal revenue code says an IRA is tax exempt but is still subject to the tax imposed by section 511 on the unrelated business income of charitable and other exempt organizations. Publication 598 confirms that IRAs, including traditional, Roth, SEP, and SIMPLE IRAs, are subject to it.

What is UBIT in an IRA?

Unrelated business income tax is a tax the IRA itself owes on certain income, reported on Form 990-T.

How a UBIT IRA situation arises

It arises when an IRA earns income from a business that is unrelated to its exempt purpose, or income from property bought with borrowed funds.

The rules come from those for exempt organizations. An IRA is treated like any other tax exempt entity for this purpose, and its tax deferred or tax free status doesn’t shield certain income.

Unrelated business taxable income (UBTI) defined

Under section 512(a)(1), unrelated business taxable income (UBTI) is gross income from any unrelated trade or business regularly carried on, less directly connected deductions.

Section 513(a) defines an unrelated trade or business as one not substantially related to the organization’s exempt purpose. For an IRA, an active business activity it runs is generally unrelated.

What qualifies as UBIT?

Two kinds of income earned by an IRA usually create UBTI in self directed IRA investments and other alternative investments.

Business income from partnerships and LLCs: how IRAs incur UBIT

If the IRA owns part of operating businesses taxed as partnerships, or owns limited liability companies taxed as partnerships or disregarded entities, the IRA’s share of income from the business activity can be considered UBTI. Section 512(c) says a partner’s share counts whether or not it’s distributed.

That’s why master limited partnerships and other limited partnerships can create unrelated business income for an IRA, even in a regular brokerage account.

Unrelated debt-financed income (UDFI)

Section 514 adds unrelated debt financed income, or UDFI. When an IRA buys property with debt financing, the portion of income generated by the debt-financed share is treated as unrelated business taxable income (UBTI), even if the income would otherwise be excluded, such as rent.

Income generated by IRA investments that is usually not UBTI

Section 512(b) excludes most passive investment income:

  • Dividends, interest, and annuities.
  • Royalties.
  • Rents from real property, with exceptions.
  • Gains from selling property, except inventory or property held for sale to customers.

So capital gains on stocks, interest on a bond, and dividends from a C corporation are generally not unrelated business income, unless the investments were bought with debt. Publication 598 lists corporate stock among sources of debt-financed income.

The rent exclusion has limits. It doesn’t cover rent if personal property makes up more than 50% of the total, or if rent depends on the tenant’s income or profits.

Debt-financed income (UDFI) and acquisition indebtedness

Debt-financed income is a common way self directed IRA investors in real estate incur UBIT.

What counts as acquisition indebtedness

Under section 514(c), acquisition indebtedness is debt incurred to buy or improve property. It also includes debt incurred before or after the purchase if it wouldn’t have been incurred otherwise, or was reasonably foreseeable. Property acquired subject to a mortgage counts too.

Under section 514(b), property is debt-financed if it produces income and has acquisition indebtedness during the year, or within 12 months before the IRA sells it.

Borrowing to buy property can make part of the income taxable.

The UDFI percentage

The taxable share is the average acquisition indebtedness for the year divided by the property’s average adjusted basis, capped at 100%. Deductions are allowed in the same proportion, and depreciation must use the straight-line method.

Rental income: no real estate exception for IRAs

Section 514(c)(9) exempts certain real property debt for “qualified organizations,” such as educational organizations and qualified retirement plan trusts under section 401. IRAs are not on that list.

So when an IRA buys investment property or rental property with a non recourse loan, part of the rental income and part of any gain on sale can be UDFI.

How unrelated business income tax (UBIT) is calculated

The $1,000 specific deduction

Section 512(b)(12) allows a specific deduction of $1,000. The amount is set in the statute and isn’t adjusted for inflation. Only one is allowed, however many unrelated businesses the IRA has.

The deduction comes off UBTI. It doesn’t make the first $1,000 of gross income tax-free; the separate $1,000 gross income test below decides whether the IRA must file.

Separate trades or businesses

Under section 512(a)(6), UBTI is figured separately for each unrelated business. A loss from one can’t offset income from another, and each is floored at zero.

2026 trust tax rates

IRAs pay unrelated business income tax at trust tax rates under section 511(b), which for 2026 range from 10% to 37%. Revenue Procedure 2025-32 sets the 2026 brackets for trusts:

  • 10% of taxable income up to $3,300.
  • $330 plus 24% of the excess over $3,300, up to $11,700.
  • $2,346 plus 35% of the excess over $11,700, up to $16,000.
  • $3,851 plus 37% of the excess over $16,000.

Trust brackets are compressed, so UBTI taxed in an IRA reaches the top rate fast.

Illustrative example

This is simplified and hypothetical. An IRA buys an investment property with a $100,000 non-recourse loan. For the year, average acquisition indebtedness is $100,000 and average adjusted basis is $200,000, so the UDFI percentage is 50%. If net rental income is $10,000, the debt-financed share is $5,000. After the $1,000 specific deduction, $4,000 is taxable. At 2026 trust rates, the IRA would pay $330 plus 24% of $700, or $498.

Real returns involve more items and a larger tax liability is possible, so a tax professional should prepare the actual figures.

Filing Form 990-T for an IRA

The Form 990-T instructions say the trustee of an IRA, SEP IRA, SIMPLE IRA, or Roth IRA must file Form 990-T when the account has $1,000 or more of gross income from an unrelated business. A custodian is treated as a trustee.

The $1,000 gross income threshold and other rules

Key rules from the instructions on how to file Form 990-T:

  • Each IRA is a separate trust and needs its own employer identification number when filing for $1,000 or more of gross income.
  • The IRA never uses the owner’s Social Security number or the trustee’s own EIN.
  • The return is due by the 15th day of the 4th month after the IRA’s tax year ends.
  • Form 990-T must be filed electronically.
  • Individual retirement annuities, unlike IRAs, aren’t subject to UBIT.

Publication 590-A also states the $1,000 threshold and the due date.

Who pays tax?

The IRA pays the tax from IRA funds, since the tax liability belongs to the IRA, not the owner. Ask your self directed IRA custodian how it handles Form 990-T, who prepares it, and how the IRA will pay UBTI tax from the retirement account. Plan for that before you invest.

How to avoid UBIT

You can’t always avoid it, but common approaches include:

  • Buying real estate without debt financing, so there’s no acquisition indebtedness.
  • Paying off the loan more than 12 months before a planned sale.
  • Holding business investments through a C corporation, whose dividends are excluded, though the corporation pays its own tax.
  • Choosing IRA investments that produce interest, dividends, or rents rather than income from an active business activity.

Each option has trade-offs. A blocker C corporation adds a layer of corporate tax, and paying cash means less leverage. Weigh the tax considerations with a tax advisor before you invest, and get tax advice specific to your investments.

When do you owe UBIT? A quick check

You may owe UBIT if your self directed IRA owns:

  • A partnership or LLC interest in an operating business.
  • Master limited partnerships.
  • Real estate bought with a mortgage or other debt.
  • Any active trade or business the IRA runs directly.

If gross income generated by these is $1,000 or more in a year, the trustee must file Form 990-T for the retirement account.
