State Tax Issues for Self-Directed IRA Investments: 2026 Complete Guide to State UBTI Filing Rules

When a Self-Directed IRA generates Unrelated Business Taxable Income (UBTI), the federal tax obligation under IRC §511 is just the beginning. The IRA files Form 990-T with the IRS and pays federal tax at the trust rate — but in most states where the IRA holds income-producing assets, a parallel state-level obligation exists. That state obligation has its own form, its own due date, its own rate, and in many cases its own definition of what qualifies as UBTI.

This catches Self-Directed IRA investors off guard constantly. A California IRA owner who buys a leveraged rental property in Texas, a Florida IRA that holds a partnership interest doing business in New York, or a Colorado IRA investing in a multi-state LLC — each scenario creates a state filing question that is entirely separate from the federal Form 990-T analysis.

This guide covers the full framework: which states tax IRA UBTI, how rates and forms differ, how multi-state investments are apportioned, and what happens when an IRA holds assets across multiple jurisdictions. If you need the federal baseline first, review our guides on UBIT explained for Self-Directed IRAs, Form 990-T filing for Self-Directed IRAs, and the mechanics of UBIT vs. UDFI for IRA investors.

Quick Answer: State UBTI Tax Rules at a Glance

• Most states that have an income tax also tax UBTI earned by IRAs. Because IRAs are treated as trusts under federal law, states that tax trust income generally extend that tax to UBTI earned by IRAs — even though the IRA is otherwise tax-exempt for retirement purposes.
• The filing obligation follows the source of income, not the IRA owner’s residence. If a California IRA owner holds a leveraged rental property in North Carolina, the UBTI from that property is subject to North Carolina state tax — not California state tax — because the income is sourced to North Carolina.
• State rates vary dramatically. California’s top rate on UBTI is 13.3% (matching its individual top rate applied through the franchise tax system). States like Texas, Florida, Nevada, and Wyoming have no individual income tax and generally do not tax IRA UBTI. Most states with income taxes fall in the 4–9% range.
• State filing forms are not Form 990-T. Each state has its own form. California uses Form 109. New York uses Form CT-13 (for exempt organizations). Illinois uses Form IL-990-T. Failure to file the correct state form — even if the federal 990-T is filed correctly — constitutes a separate state violation.
• Multi-state investments require apportionment. When an IRA holds an interest in a business or partnership operating in multiple states, the UBTI must be apportioned among those states using each state’s apportionment formula.
• The $1,000 federal specific deduction under IRC §512(b)(12) does not automatically apply at the state level. Some states conform to it; others do not. Always verify the state’s starting point for the UBTI calculation.

Why States Tax IRA UBTI: The Legal Framework

Under federal law, IRAs are tax-exempt trusts under IRC §408. That exemption covers ordinary investment income — interest, dividends, capital gains from passive investments. But when UBTI is generated, that income loses its exempt character under IRC §§511–514 and becomes taxable at the trust rate.

States follow a parallel logic. Most states have their own version of the federal exemption for retirement accounts, but they also have their own version of the UBTI tax. The key principle: the state taxes the income at its source. If the income-producing activity — a rental property, a partnership, a leveraged investment — is located in or connected to a particular state, that state has taxing jurisdiction over the UBTI generated by that activity, regardless of where the IRA owner lives.

This is the same nexus principle that applies to out-of-state businesses generally. An IRA holding real property in a state, or an interest in a partnership with operations in a state, creates sufficient nexus for that state to impose its income tax on the UBTI portion of earnings from that activity.

State-by-State Overview: Major States and Their UBTI Rules

The following covers the states most commonly encountered by Self-Directed IRA investors. Always consult a tax professional for current rates, forms, and thresholds, as state tax laws change frequently.

This table is illustrative, not exhaustive. There are 41 states plus the District of Columbia that impose some form of income tax, and the majority of them have provisions that reach UBTI earned by tax-exempt entities including IRAs. The only states with no state income tax exposure at all are Alaska, Florida, Nevada, New Hampshire (on earned income; investment income tax eliminated), South Dakota, Tennessee (income tax eliminated), Texas, Washington, and Wyoming.

The Source-of-Income Rule: Where Your IRA Pays State Tax

The most important concept for state UBTI is that tax follows the income to its source — not to the IRA owner’s home state. Here is how that plays out in practice:

Multi-State Investments: Apportionment and Allocation

When a Self-Directed IRA holds an interest in a partnership, LLC, or other pass-through entity that operates in multiple states, the UBTI must be apportioned among those states. This is one of the most complex areas of state UBTI compliance.

Each state uses its own apportionment formula. Traditionally, states used a three-factor formula (property, payroll, and sales weighted equally). Most states have now moved to a single-sales-factor or heavily sales-weighted formula. The result is that the same UBTI can be apportioned differently in each state where the entity operates.

California: The State with the Highest Exposure

California deserves special attention because it has the highest state income tax rates in the country and aggressive enforcement of its tax on exempt organization income. Key California-specific rules for Self-Directed IRA investors:

• California imposes an 8.84% minimum franchise tax on the net income of exempt organizations, including IRAs, that are doing business in California or have California-source income. For income above certain thresholds, higher individual rates may apply through the trust tax system.
• California’s definition of UBTI does not always conform to federal law. California has its own modifications, and certain items that are excluded at the federal level may not be excluded in California. For example, California does not always conform to federal changes made by the Tax Cuts and Jobs Act of 2017 regarding UBTI siloing rules under IRC §512(a)(6).
• California real property always creates California filing obligations. Any IRA holding leveraged real property located in California will have a California Form 109 filing requirement regardless of where the IRA owner lives.
• California’s franchise tax minimum is $800 per year for many entity types, which can apply even if the net UBTI is minimal. This minimum tax can make low-income California properties economically unattractive for leveraged IRA investments.
• The California Franchise Tax Board (FTB) actively audits exempt organization returns including Form 109 filings. Incomplete or inaccurate filings attract scrutiny.

New York: High Rates and City-Level Complications

New York imposes a 9% flat tax on UBTI earned by exempt organizations, including IRAs with New York-source income. For IRA investors with properties or business interests in New York City specifically, an additional New York City unincorporated business tax (UBT) at 4% may apply, creating a combined state-plus-city effective rate of approximately 13% on New York City-source UBTI.

New York generally conforms to the federal UBTI definitions but has its own modifications. New York filing is made on Form CT-13 for most exempt organization situations. Due dates generally align with the federal Form 990-T due date (the 15th day of the 5th month after the close of the tax year, with extensions available).

The UBTI Siloing Rule and Its State Implications

Starting with tax years beginning after December 31, 2017, the Tax Cuts and Jobs Act added IRC §512(a)(6), which requires that UBTI from each separate unrelated trade or business be computed separately — losses from one activity cannot offset income from another. This “siloing” rule applies at the federal level.

States vary significantly in their conformity to this rule. As of 2026:

• Most states that have updated their conformity dates (typically updated to the current IRC) follow the siloing rule.
• States with older “fixed date” conformity (states that conform to the IRC as of a specific prior date) may not apply §512(a)(6), meaning losses from one UBTI activity could still offset gains from another at the state level even though they cannot federally.
• California specifically does not conform to §512(a)(6) as of recent tax years, which can create planning opportunities for IRAs with multiple California-source UBTI activities.

This conformity patchwork means the net UBTI calculation at the state level can be materially different from the federal calculation — and in some states, it can be lower due to non-conformity with restrictive federal rules.

Filing Deadlines and Extensions by State

Federal Form 990-T is due on the 15th day of the 5th month after the close of the organization’s tax year. For calendar-year IRAs, that is May 15. An automatic extension to November 15 is available by filing Form 8868.

State deadlines vary. Most states align with or are close to the federal due date, but there are exceptions:

• California Form 109: Due the 15th day of the 5th month after year-end (May 15 for calendar-year filers), with automatic extension to the 15th day of the 11th month (November 15).
• New York Form CT-13: Generally due 30 days after the federal Form 990-T due date.
• Illinois Form IL-990-T: Due the same date as the federal return, with extension available.
• Massachusetts Form M-990-T: Due the 15th day of the 5th month, aligned with federal.

Missing a state filing deadline results in state-level penalties and interest, which accrue independently of any federal penalties. An IRA that files its federal Form 990-T on time but misses a state deadline can still face significant state penalties.

Common Mistakes That Cost IRA Investors Real Money

• Assuming federal filing satisfies state obligations. Filing Form 990-T with the IRS does not file anything with any state. Every state filing is entirely separate, on a separate form, with a separate check sent to the state revenue department.
• Filing in the IRA owner’s home state instead of the source state. The obligation follows the income source. A Texas IRA owner with an Illinois rental property files in Illinois — not Texas (which has no income tax) and not in any other state.
• Ignoring the California $800 minimum franchise tax. Even if the IRA’s California-source UBTI is small or zero, the $800 minimum tax may still apply if the IRA is “doing business” in California through property ownership or investment activity.
• Not accounting for city-level taxes. New York City, Philadelphia, and a handful of other municipalities impose local business income taxes that can reach IRA UBTI. These are separate from state filings.
• Using the wrong apportionment formula. States update their apportionment rules, and using an outdated formula (three-factor when the state now uses single-sales-factor, for example) produces an incorrect tax calculation.
• Assuming state and federal UBTI are always the same number. State conformity issues, different starting points, and different modifications mean the state UBTI figure often differs from the federal figure. Always compute state UBTI separately.
• Not reserving enough cash inside the IRA. State taxes are paid by the IRA from its own assets, just like federal UBTI tax. If the IRA is a leveraged real estate IRA with limited liquidity, state tax bills — especially in high-rate states like California and New York — can create cash flow pressure.

How Sophisticated Investors Plan Around State UBTI

Experienced Self-Directed IRA investors factor state UBTI into their deal underwriting before they acquire assets. Here is the framework:

• Map the state exposure before closing. Identify every state where the investment will produce income. Research whether each state taxes IRA UBTI, the applicable rate, the filing form, and whether state conformity to federal UBTI rules creates any differences in the taxable base.
• Model state taxes as a line item in the pro forma. For a California commercial property, budget the 8.84% franchise tax (or applicable rate) on projected net UBTI in addition to federal tax. For a New York property, budget federal + 9% state + potential 4% NYC UBT. These are real costs that affect cash-on-cash return.
• Consider state tax rates when comparing investment locations. All else being equal, a leveraged rental property in Texas or Florida generates no state UBTI tax. The same property in California generates federal + state tax at combined effective rates that can exceed 50% on net UBTI at high income levels. This is a legitimate factor in investment location decisions.
• Hire a CPA with multi-state exempt organization experience. Most general practitioners cannot competently prepare multi-state Form 990-T plus state equivalent filings. This requires someone with specific experience in exempt organization taxation across multiple state jurisdictions. See our companion article on how to work with a CPA on SDIRA tax reporting for exactly what to look for.
• Maintain a state filing calendar. Each state has its own due date. A master calendar with every state filing obligation, due date, and extension deadline prevents missed filings and the penalties that come with them.
• Keep state tax payments inside the IRA. Do not pay state taxes on IRA UBTI from personal funds. The tax is an obligation of the IRA, paid from IRA assets. Paying it personally could constitute an indirect contribution or prohibited transaction analysis.

FAQ

Does my IRA have to file a state tax return if I live in a state with no income tax?

Your state of residence is largely irrelevant. The filing obligation is determined by where the income is sourced. If your Florida-based IRA owns a leveraged rental property in Illinois, the IRA must file an Illinois Form IL-990-T for Illinois-source UBTI, even though you live in Florida and Florida has no income tax. You would owe nothing to Florida, but you owe Illinois state tax on Illinois-source UBTI.

What if my IRA holds a partnership interest in a business operating in 10 states?

You may have filing obligations in each of those 10 states, depending on whether each state taxes exempt organization UBTI and whether the apportioned income exceeds each state’s filing threshold. The partnership’s K-1 should provide state-level income information, but you or your CPA will need to apply each state’s apportionment formula and filing rules independently. This is exactly the scenario where a CPA with multi-state exempt organization experience is not optional — it is essential.

Does California’s $800 minimum tax apply to my IRA even if it earns no UBTI?

Potentially yes, if the IRA is considered to be “doing business” in California. Owning California real property through an LLC taxed as a partnership, for example, can trigger the $800 minimum franchise tax on the LLC itself regardless of income level. The specific application depends on the entity structure and how the investment is held. This is a common surprise for IRA investors who acquire California properties without understanding the state’s minimum tax rules.

Are state UBTI taxes deductible on the federal Form 990-T?

State and local taxes that are directly connected to the unrelated business activity may be deductible as an allocable expense on the federal Form 990-T, subject to the same debt-financed percentage allocation rules if the income is UDFI. State income taxes on UBTI are generally considered an allocable deduction. Consult a CPA to ensure proper treatment.

Do all states start with the same UBTI number as the federal return?

No. Each state has its own conformity rules. States with “rolling conformity” automatically adopt federal IRC changes. States with “fixed date conformity” conform to the IRC as of a specific historical date and may not reflect recent federal changes — including the UBTI siloing rule under IRC §512(a)(6) added by the Tax Cuts and Jobs Act. This means the state UBTI starting point can differ from the federal UBTI, sometimes favorably for the taxpayer.

Can I deduct state UBTI taxes I paid from IRA assets as a cost basis or expense?

State taxes paid from IRA assets reduce the IRA’s cash balance but do not create a deductible expense at the individual level — the IRA owner does not get a personal deduction for taxes paid by the IRA. The taxes are paid from the IRA’s pre-tax assets and effectively reduce the IRA’s net asset value. There is no personal tax deduction for the IRA owner.

What happens if I miss a state filing deadline?

Each state imposes its own penalty and interest regime for late filings and late payments. Penalties typically range from 5% to 25% of the unpaid tax per month, subject to state caps. Interest accrues from the original due date. Some states also impose minimum penalties for failure to file. These accumulate independently of any federal penalties and can exceed the original tax liability if unaddressed for multiple years.
