Tax
UBIT and debt-financed property in an IRA
Why leverage inside a retirement account can create a tax bill in a tax-exempt account.
This page defines one term. If you have arrived here from a listing or a broker's summary, the useful order is: read what it is, then read what it does not tell you, and only then look at the number you were quoted. What would mislead: any single measure on a property is a summary of one year, one assumption or one document. None of them describes a whole investment, and the misreading section below is there because each of these terms has one that is extremely common.
What it is
A tax-exempt account such as an IRA is still taxable on unrelated business taxable income. Rent from real property is generally excluded from UBTI — but that exclusion does not extend to income from debt-financed property. Where an IRA owns property with acquisition indebtedness, a proportion of the income, based on the debt relative to the property's basis, becomes unrelated debt-financed income and is taxable.
The same treatment reaches gain on sale of debt-financed property, and income from an operating business held through a pass-through entity in an IRA is generally UBTI in full. Income from a REIT, by contrast, is a dividend to the account and is not normally UBTI, which is one structural reason listed vehicles behave differently inside retirement accounts.
When UBTI applies, the account itself files a return and pays tax at trust rates, which reach the top bracket at a very low level of income. There is a small specific deduction; the IRS publication on unrelated business income is the authority on the mechanics.
What it tells you
That a leveraged property inside an IRA is not fully tax-sheltered, and that the account can owe tax and have a filing obligation of its own.
What it does not tell you
How much. The calculation depends on the average acquisition indebtedness over the year relative to the average adjusted basis, and on the account's own deductions.
The common misreading
Assuming that anything inside an IRA is tax-free. Leverage is the trigger, trust tax rates compress quickly, and the prohibited-transaction rules on dealings with disqualified persons are a separate and severe constraint on self-directed real estate.
Where it sits in the sequence
Every commercial deal runs the same arithmetic in the same order. This measure is one line in it.
The list below is how a whole deal is worked out, from the rent on the schedule to the cash an owner keeps. Find the step this term belongs to and you can see what it has already counted and what it has not. What would mislead: quoting one line of this sequence as though it were the answer. Each step subtracts something real, and the ones after it subtract more.
-
Rent roll
Contract rent, tenant by tenantStart from the leases, not from a summary. Each line has a start date, an expiry, an escalation schedule, options, and any free rent or unamortised concession still running. The rent roll is a legal document set, and the estoppel certificates are how a buyer confirms the tenants agree with it. -
Potential gross income
Contract rent + market rent on vacant space + other income + expense recoveriesWhat the property would produce fully leased, including parking, signage, storage, late fees and the reimbursements tenants owe for taxes, insurance and common-area costs. Recoveries are income and the matching expense is an expense — netting them hides the recovery ratio. -
Effective gross income
Potential gross income − vacancy − credit loss − concessionsDeduct what will not actually be collected: physical vacancy, tenants who do not pay, and concessions granted. Using an assumed market vacancy rather than the property's own history is one of the most common places a model becomes optimistic. -
Operating expenses
Taxes + insurance + utilities + repairs + management + admin + payrollThe cost of running the building for a year. Two lines deserve independent verification rather than acceptance: property taxes, which are frequently reassessed on a sale, and insurance, which is quoted to the buyer and not inherited from the seller. A market management fee belongs here even if the current owner charges none. -
Net operating income
Effective gross income − Operating expenses = NOIThe property's own income, before financing and before tax. This is the number that value, cap rate and every lender covenant are calculated from, which is exactly why it is the number most often presented flatteringly. -
Value and cap rate
Value = NOI ÷ Cap rate · Cap rate = NOI ÷ PriceOne equation used in both directions. Divide NOI by a cap rate to estimate value; divide NOI by a price to see what a deal is being priced at. Because value is derived from NOI, every dollar added to or removed from NOI moves the value by a multiple of itself. -
Capital items below the line
NOI − capital expenditure − tenant improvements − leasing commissionsExcluded from NOI by convention, but paid in cash. Roofs, parking lots, HVAC replacement, fitting out space for a new tenant and the commission that won the lease all come out of the same account. A reserve for them is the difference between an honest analysis and a brochure. -
Debt service
Cash flow before tax = NOI − annual debt service (− capital items)Interest and principal on the loan. This is where DSCR is tested, where the loan constant decides whether leverage is adding to or subtracting from cash flow, and where a covenant breach can divert income into a lender-controlled account before the owner sees it. -
After tax
Taxable income = NOI − interest − depreciation ± other adjustmentsCash flow and taxable income are different numbers. Depreciation is deducted though no cash left, principal repayment is cash out though it is not deductible, and the resulting loss may be suspended under the passive activity rules rather than used. At sale, recapture and gain settle the difference.

Where do these numbers come from in a real deal?
This section is a structural reference, not investment, tax or legal advice, and nothing in it recommends buying, selling or financing any property. It contains no market quotes: no current cap rates, rents or prices, because those are negotiated privately and are not publicly quotable. Tax rules described here are general US federal mechanisms that change with legislation, and state and local rules differ. Verify anything that matters with an attorney, an accountant and an appraiser who know the specific property and jurisdiction.
