Does a self-directed IRA only make sense unleveraged, or does UBIT still leave room for debt-financed deals

The depreciation point took me three reads before it clicked. If the account already doesn't pay tax on the income, a deduction against that income is worth nothing. So the leveraged deal inside an IRA is carrying the cost of debt without the tax benefit of debt. That seems like a big deal and I never see it mentioned first.

The split is the more durable answer. The pure version of any policy tends to die the first time a good opportunity shows up that doesn't fit it. Better to decide in advance what percentage of the account can go into something that generates a 990-T, write the number down, and stop relitigating it every time a sponsor sends a deck. A reasonable starting allocation is 20 percent, with room to use about half of it before revisiting the number.

The strictly clean structure holds up as the stronger default for most self-directed accounts. Unrelated debt-financed income filing carries an annual deadline and typically needs a preparer every year, and that recurring cost is easy to underweight against the extra basis points leverage might add. An account worth checking only twice a year is usually worth more than the incremental return.

The framing in the poll skips a variable that matters more than the tax rate, which is who computes the number. On a leveraged syndication, the UBIT calculation depends on the sponsor's debt-financed percentage, how it changes across the hold, and whether the K-1 arrives with the unrelated business taxable income figures actually filled in. Plenty of PPMs state plainly that the fund may generate UBTI for tax-exempt investors and then say nothing about whether the K-1 will report it in a usable form. If it doesn't, a preparer is reconstructing it, and that's billable hours every year, not just in one bad year. So before pricing the tax, ask the sponsor in writing whether the K-1 will include the UBTI reporting on the relevant lines and by what date it typically goes out. A sponsor who has worked with tax-exempt investors before answers that in one sentence. One who hasn't will say they need to check with their accountant. The compliance-focused view in this thread is more defensible than it's getting credit for. The annual compliance obligation is a real recurring cost and a real recurring failure point. The tax rate is only half of what's being bought.

A few definitions for anyone reading this cold, since the thread moves fast.

UBIT is unrelated business income tax. A retirement account is tax-exempt, and the rules stop that exemption from covering income that looks like an operating business or income earned on borrowed money. Interest from lending, rent from property the account owns outright, and gains on passive positions generally sit outside it. Income tied to borrowed money and profits from active businesses such as a flipping operation generally sit inside it. When it applies, the account files Form 990-T, the threshold where filing starts is low, and the rates follow the trust schedule and rise quickly. Confirm the current thresholds and rates with a tax professional, since these figures change.

On ember's point about depreciation, the reason it lands is that deductions reduce taxable income. An account that already owes no tax on rental income gets nothing from a deduction against it. That is a real structural difference between holding a leveraged property personally and holding one inside an IRA, and it is separate from the UBIT question.

One thing the poll options can't capture: the answer depends on how much of your total retirement balance you are moving and what the rest of it is doing. An account that holds nothing else has different tolerance for an annual filing obligation than one where the self-directed piece is a slice of something larger.

What warrant said about the K-1 is the practical test. If the sponsor cannot tell you how UBTI will be reported and when, you cannot price the decision either way.
