Depreciation and Deductions for Leveraged IRA Property

The combination of leverage and retirement account investing is powerful — but it triggers one of the most misunderstood provisions in the U.S. tax code. Under IRC §514, when a tax-exempt organization (including an IRA) acquires property using debt, a proportionate share of the income from that property loses its tax-exempt status. That share is called Unrelated Debt-Financed Income (UDFI), and it is taxed as Unrelated Business Taxable Income (UBTI) under IRC §511.

What many investors miss is the other side of that equation: the IRS also allows a proportionate share of deductions — including depreciation, mortgage interest, property taxes, insurance, and repairs — to offset UDFI before tax is calculated. Understanding how those deductions work is where sophisticated investors gain a real analytical edge.

This guide covers the complete mechanics, with worked examples, IRS citations, and the exact calculations a CPA would run.

Quick Answer: Key Rules at a Glance

UDFI is triggered by debt. Under IRC §514, any income from property acquired or improved with borrowed funds is potentially debt-financed income. For IRAs, the only permissible debt is non-recourse financing — the lender can only claim the property, not other IRA assets.
The debt-financed percentage determines taxable income. The fraction equals average acquisition indebtedness divided by average adjusted basis. Only that percentage of gross income is UDFI.
Deductions are allocated by the same fraction. Under IRC §514(a)(2), the same debt-financed percentage applies to allocable deductions. If 60% of income is UDFI, then 60% of depreciation, interest, and other allocable expenses offset that UDFI.
Depreciation is calculated on the full basis, then the UDFI fraction is applied. The IRA does not get to depreciate only the financed portion — it depreciates the whole property and applies the ratio.
A $1,000 specific deduction applies. Under IRC §512(b)(12), tax-exempt organizations including IRAs get a $1,000 deduction against UBTI before the tax rate applies.
The tax rate is the trust rate. IRAs are taxed as trusts. For 2025 tax year, the top trust rate of 37% kicks in at just $15,200 of UBTI. This makes expense tracking extremely valuable.

The Statutory Framework: What the IRS Actually Says

The UDFI rules live in IRC §§511–514. Here is how the relevant provisions fit together:

IRC §511 imposes a tax on the unrelated business taxable income of tax-exempt organizations, including IRAs.
IRC §512 defines UBTI and provides certain modifications, including the $1,000 specific deduction under §512(b)(12).
IRC §514(a)(1) defines “unrelated debt-financed income” as the amount of gross income derived from debt-financed property, multiplied by the debt-financed percentage.
IRC §514(a)(2) allows deductions directly connected to debt-financed property, also multiplied by the debt-financed percentage.
IRC §514(b) defines “debt-financed property” as any property held to produce income for which there is acquisition indebtedness at any time during the taxable year (or the preceding 12 months if the property is disposed of).
IRC §514(c) defines “acquisition indebtedness” as debt incurred in acquiring or improving the property, or debt that would not have been incurred but for the acquisition.

For IRA investors, the most important practical point is that only non-recourse loans qualify. A recourse loan — where the borrower is personally liable — would constitute a prohibited transaction under IRC §4975 because it involves extension of credit between a disqualified person (you) and the IRA. The IRA itself must be the borrower, with no personal guarantee from the account holder.

How the Debt-Financed Percentage Is Calculated

The debt-financed percentage is the core calculation driving all UDFI math. Under IRC §514(a)(1), it is defined as:

Debt-Financed Percentage = Average Acquisition Indebtedness ÷ Average Adjusted Basis

Both figures are calculated as averages over the tax year (or the period the property was held, if less than a full year).

Average Acquisition Indebtedness is the average of the outstanding principal balance of all acquisition debt on the property at the beginning of each month during the year. Under Treas. Reg. §1.514(a)-1(a)(2), if the property was held for fewer than 12 months, the average uses only the months it was held.

Average Adjusted Basis is the average of the property’s adjusted tax basis at the beginning and end of the year (or holding period). The adjusted basis starts at the purchase price allocated to depreciable improvements (not land), then is reduced each year by accumulated depreciation.

Worked Example: Calculating the Debt-Financed Percentage

An IRA purchases a small commercial building on January 1, 2025, for $400,000. Of that, $80,000 is allocated to land (non-depreciable) and $320,000 to the building. The IRA finances the acquisition with a $200,000 non-recourse loan. The loan balance on January 1, 2025 is $200,000, and after principal payments through the year, it stands at $194,000 on December 31, 2025.

Average Acquisition Indebtedness: ($200,000 + $194,000) ÷ 2 = $197,000

Using straight-line depreciation over 39 years (commercial real estate), annual depreciation on $320,000 = $320,000 ÷ 39 = $8,205.

Adjusted basis, beginning of year: $320,000 (building) + $80,000 (land) = $400,000

Adjusted basis, end of year: $400,000 − $8,205 depreciation = $391,795

Average Adjusted Basis: ($400,000 + $391,795) ÷ 2 = $395,898

Debt-Financed Percentage: $197,000 ÷ $395,898 = 49.76%

This means roughly 49.76% of the property’s gross income is UDFI — and 49.76% of allocable deductions can offset it.

What Expenses Are Deductible Against UDFI?

Under IRC §514(a)(2), deductions “directly connected with” the debt-financed property are allowable against UDFI — but only in the same proportion as the debt-financed percentage. The IRS interprets “directly connected” to mean expenses that have a proximate and primary relationship to carrying on the activity that produces the income.

Expense Category	IRS Treatment	Notes for IRA Investors
Depreciation	Allocable deduction under IRC §514(a)(2)	Calculated on full building basis; residential = 27.5 yr, commercial = 39 yr straight-line
Mortgage Interest	Allocable deduction — directly connected to acquisition indebtedness	Only interest on the non-recourse note; no personal guarantee allowed
Property Taxes	Allocable deduction as a carrying cost of the property	Real property taxes assessed against the IRA-owned property
Insurance Premiums	Allocable deduction	Property and liability insurance on the IRA-owned asset
Repairs & Maintenance	Allocable deduction if directly connected to income production	Must be ordinary repairs; capital improvements are added to basis instead
Property Management Fees	Allocable deduction	Paid to a third-party manager — not to a disqualified person
Utilities Paid by IRA	Allocable deduction if part of rental arrangement	Common in triple-net leases where tenant pays; rare in gross leases
Capital Improvements	Not immediately deductible — added to depreciable basis	Depreciated over the remaining useful life of the improvement
Custodian / Admin Fees	Generally not allocable to specific property income	May be deductible at the account level; consult a CPA

The critical point: you do not deduct 100% of these expenses against UDFI. You deduct only the debt-financed percentage. In the example above (49.76%), if the property generated $14,000 in mortgage interest expense for the year, only $14,000 × 49.76% = $6,966 would be deductible against UDFI. The remaining 50.24% of income — and the corresponding expenses — remain fully tax-sheltered inside the IRA.

Depreciation on Leveraged IRA Property: The Full Mechanics

Depreciation is the largest non-cash deduction available on real estate, and it is one of the most powerful tools for reducing net UDFI even on a leveraged IRA property. Here is how it works in practice:

Depreciation Method: Under IRS rules, real property held by tax-exempt organizations uses the Alternative Depreciation System (ADS) under IRC §168(g), not the regular MACRS depreciation used by taxable owners. Under ADS:

Residential rental property: 30-year straight-line (compared to 27.5 years under regular MACRS)
Commercial real property: 40-year straight-line (compared to 39 years under regular MACRS)
Land improvements: 20-year straight-line under ADS

This is a meaningful distinction. A taxable investor can depreciate a $300,000 residential building over 27.5 years ($10,909/year). An IRA under ADS depreciates the same building over 30 years ($10,000/year). The difference compounds over time and affects net UDFI calculations each year.

Worked Example: Full UDFI Calculation with Depreciation

Using the commercial property from the prior example (purchased January 1, 2025, for $400,000 — $320,000 building, $80,000 land — $200,000 non-recourse loan). Assume the following 2025 annual figures:

Gross Rental Income: $36,000

Allocable Expenses (100%):

• Depreciation (ADS, 40 yr): $320,000 ÷ 40 = $8,000
• Mortgage Interest: $14,200
• Property Taxes: $4,800
• Insurance: $1,400
• Repairs & Maintenance: $2,200
• Property Management (8%): $2,880
Total Allocable Expenses: $33,480

Debt-Financed Percentage: 49.76% (from prior calculation)

Step 1 — UDFI (Gross): $36,000 × 49.76% = $17,914

Step 2 — Allocable Deductions: $33,480 × 49.76% = $16,659

Step 3 — Net UDFI before specific deduction: $17,914 − $16,659 = $1,255

Step 4 — IRC §512(b)(12) specific deduction: − $1,000

Net UDFI / UBTI: $255

Estimated Tax (37% trust rate): $255 × 37% = $94.35

On a $400,000 property generating $36,000 in gross rent, the IRA owes approximately $94 in tax for 2025. Without tracking depreciation and other allocable deductions properly, an unsophisticated investor might have assumed a far larger tax bill — or been caught off guard entirely.

Mortgage Interest and Financed Property: What Counts

Mortgage interest on the non-recourse loan is deductible in proportion to the debt-financed percentage, but there are rules about what qualifies as deductible acquisition indebtedness interest:

Only the non-recourse loan on the specific property creates acquisition indebtedness. Debt secured by other IRA assets, or personal debt guaranteed by the account holder, does not qualify and would constitute a prohibited transaction.
Points paid to originate the loan are generally treated as prepaid interest and must be amortized over the life of the loan rather than deducted in the year paid.
Refinancing can affect acquisition indebtedness calculations. Under IRC §514(c)(1), debt incurred to refinance acquisition indebtedness retains its character as acquisition indebtedness, but only to the extent of the remaining principal on the original debt. Cash-out refinancing above the original balance creates a more complex analysis.
Balloon payments and interest-only loans keep the principal balance — and therefore the debt-financed percentage — higher for longer, increasing UDFI exposure each year compared to a fully amortizing loan.

Interest-Only vs. Amortizing: The UDFI Difference

Consider the same $400,000 property with a $200,000 loan. Under an interest-only structure, the principal never declines, so the average acquisition indebtedness stays near $200,000 all year. Under a 25-year amortizing non-recourse loan at 7%, the balance declines each month. By year 5, the outstanding balance may be around $184,000 — meaningfully reducing the debt-financed percentage and therefore the UDFI exposure. Over a 10-year hold, the difference in cumulative UBTI tax paid can be substantial. Amortizing loans reduce UDFI exposure over time; interest-only loans keep it flat.

The 11-Month Rule and Disposition Year Calculations

Under IRC §514(b)(1)(D) and related Treasury regulations, if debt-financed property is disposed of during the year, the debt-financed percentage for that year uses the average indebtedness and average basis over the period the property was held, not the full calendar year. Additionally, gain on the sale of debt-financed property may itself be UDFI — not just the rental income earned prior to sale.

Under IRC §514(a)(1), gain on disposition of debt-financed property is included in UDFI to the extent of the applicable debt-financed percentage. Specifically, if the property was debt-financed during any of the 12 months before the disposition, a portion of the gain is treated as UDFI. This catches investors who pay off the loan right before selling — the 12-month look-back prevents a simple pre-sale payoff from eliminating UDFI on the gain.

Common Mistakes That Cost IRA Investors Real Money

Assuming all IRA income is tax-free. This is the most expensive mistake. Leveraged IRA real estate with meaningful net income after expenses can generate thousands of dollars in UBTI tax annually.
Not filing Form 990-T. If an IRA has $1,000 or more of gross UBTI in a year, it must file Form 990-T. The IRA custodian is the filer, but the account holder is responsible for ensuring it is done. Failure to file can result in penalties.
Using the wrong depreciation method. Taxable investors use regular MACRS; IRAs use ADS. Using the wrong useful life overstates deductions and creates a filing error.
Not keeping contemporaneous expense records. The IRS requires that deductions be substantiated. Receipts, invoices, and bank records for every allocable expense should be maintained and organized by tax year.
Treating capital improvements as repairs. Under the IRS “Repair Regulations” (Treas. Reg. §1.263(a)-3), expenditures that materially add to the value, substantially prolong the useful life, or adapt property to a new use must be capitalized and depreciated — not expensed. Misclassifying a roof replacement as a repair is a common and auditable error.
Ignoring the 12-month look-back on dispositions. Paying off the non-recourse loan one month before sale does not eliminate UDFI on the gain. The prior 12 months of debt are still considered.
Using recourse debt. A personally-guaranteed loan inside an IRA is a prohibited transaction under IRC §4975, subject to excise taxes and potentially causing the entire IRA to be treated as distributed.
Failing to reserve cash for the tax bill. The IRA itself must pay the Form 990-T tax from its own assets. The account holder cannot contribute additional funds to cover it without it counting as a contribution subject to annual limits.

How Sophisticated Investors Underwrite Leveraged IRA Deals

Before closing on any leveraged IRA property, serious investors build a full pro forma that models not just cash flow but after-tax return. Here is the framework:

Establish purchase price allocation. Get an appraisal or use a cost segregation study to allocate between land, building, and land improvements. This drives the depreciable basis and ADS useful life for each component.
Model the debt-financed percentage for each year of the hold. On an amortizing loan, this fraction declines over time. Plot it for years 1 through 10 (or whatever the projected hold period is) to understand how UDFI exposure changes.
Project gross rental income conservatively. Use current market rents with 0–2% annual growth. Run a stress test at flat rents.
List every allocable expense with realistic amounts. Depreciation (ADS), mortgage interest (amortized schedule), property taxes (use county assessor’s current bill), insurance, management fees (typically 8–10% of gross rents), maintenance reserve (1–2% of property value annually), and vacancy reserve (5–8% of gross rents).
Calculate net UDFI for each year. Apply the debt-financed percentage to both income and expenses. Subtract the $1,000 specific deduction.
Apply the trust tax rate to net UDFI. For 2025, the 37% bracket starts at $15,200 of UBTI. Most well-structured deals with good expense tracking will produce net UDFI well below this threshold, but high-income properties with low expense ratios (triple-net commercial, for example) can hit the top rate quickly.
Model the disposition year separately. Calculate the expected gain, apply the debt-financed percentage, and estimate the UBTI tax on the sale. This often surprises investors who assumed all appreciation would be tax-deferred.
Compare to an all-cash IRA scenario. Sometimes leverage does not improve risk-adjusted returns after accounting for UBTI, loan costs, and administrative complexity. The model should make that comparison explicit.

10-Year Hold Scenario: Leveraged vs. All-Cash IRA

Property: $500,000 residential duplex, $100,000 land / $400,000 building. Gross rents $42,000/year, growing 2% annually. Expenses: 35% of gross (before debt service). Non-recourse loan: $250,000 at 7%, 25-year amortization.

Leveraged scenario — Year 1: Debt-financed % ≈ 51%. Net UDFI after allocable deductions ≈ $1,100 before specific deduction; $100 after. Tax ≈ $37. By Year 10, as the loan amortizes, the debt-financed % falls to approximately 34%, and if rents have grown, net UDFI rises modestly — but the overall IRA equity has grown substantially through leverage.

All-cash scenario — Year 1: No UDFI. All $42,000 in rent (less expenses) accumulates fully tax-deferred. But the IRA deployed $500,000 instead of $250,000, and had no exposure to rising interest rates or debt service risk.

The right answer depends on the investor’s risk tolerance, opportunity cost of capital, and projected hold period. The point is to model it explicitly — not assume leverage is always better or always worse.

State Tax Considerations

Federal UBTI under Form 990-T does not end the analysis. Many states independently impose taxes on UBTI earned by IRAs, and some states have their own filing requirements separate from the federal Form 990-T. California, for example, imposes an 8.84% franchise tax on UBTI earned by tax-exempt organizations including IRAs, with its own state filing. New York, Massachusetts, and other high-tax states have similar rules. For more detail, see our guide to state tax issues for self-directed IRA investments.

Working with a CPA on UDFI Filings

Form 990-T preparation for a leveraged IRA real estate investment is not a standard tax return. Most retail tax preparers have never filed one. When selecting a CPA, look for:

Specific experience with IRC §§511–514 and Form 990-T preparation for IRAs (not just for nonprofits — the form is similar but the context is different)
Familiarity with non-recourse lending requirements and prohibited transaction rules under IRC §4975
Experience with ADS depreciation schedules and the distinction between repairs and capital improvements under the Repair Regulations
Ability to model multi-year UDFI projections, not just prepare a single-year return

For more on this, see our guide to working with a CPA on SDIRA tax reporting.

Should You Use Leverage Inside an IRA?

The honest answer is: it depends, and the math should drive the decision. Here is a framework:

Leverage makes sense when projected after-tax leveraged returns (accounting for UBTI, debt service, and risk) materially exceed all-cash returns, and when the investor has adequate liquidity reserves inside the IRA to service the debt and cover tax filings without needing to contribute additional funds.
Leverage may not make sense when the property is a high net-income asset (commercial triple-net, for example) where UDFI after deductions is large, when the IRA has limited liquidity to absorb vacancies or unexpected capital needs, or when the complexity cost — CPA fees, Form 990-T, lender requirements for non-recourse loans — reduces the net return below the all-cash alternative.
Leverage is particularly powerful in the early years of a hold when depreciation deductions are fresh, the debt-financed percentage is highest (meaning the largest deduction allocation), and appreciation has not yet been realized.

FAQ

Can an IRA claim depreciation on financed real estate?

Yes — but under the Alternative Depreciation System (ADS) per IRC §168(g), not regular MACRS. Residential rental property is depreciated over 30 years and commercial real property over 40 years using straight-line method. The depreciation deduction is then applied in proportion to the debt-financed percentage to reduce net UDFI.

Does every leveraged IRA property owe UBTI tax?

Not necessarily. The tax only applies if net UDFI exceeds $1,000 (after the IRC §512(b)(12) specific deduction). In many well-structured deals with normal operating expenses and meaningful depreciation, allocable deductions can reduce net UDFI to near zero — as shown in the worked example above. High-equity, low-debt properties (where the debt-financed percentage is small) also produce minimal UDFI.

What happens if I pay off the loan before selling?

Under IRC §514(b)(1)(D), the 12-month look-back rule applies. If the property was debt-financed at any point during the 12 months before the sale, a portion of the gain is still treated as UDFI. Paying off the loan right before selling does not eliminate UDFI on the gain.

Can I use a regular bank loan inside my IRA?

No. The loan must be non-recourse — meaning the lender’s only recourse in case of default is the property itself. A personally-guaranteed or recourse loan constitutes a prohibited transaction under IRC §4975 between you (a disqualified person) and the IRA. The consequences can include the entire IRA being treated as distributed and subject to income tax and penalties.

Do I need to file Form 990-T if my net UDFI is less than $1,000?

The filing threshold under IRC §6012(a)(6) is $1,000 of gross UBTI (not net). If gross UBTI exceeds $1,000, the return must be filed even if deductions reduce the net tax to zero. Always consult with a CPA on filing obligations for your specific situation.

Should I keep separate books for a leveraged IRA property?

Yes, absolutely. Maintaining a dedicated set of records for the IRA-owned property — including all income, every expense, loan statements, and depreciation schedules — is essential for accurate Form 990-T preparation and for substantiating deductions if audited. Many investors use property management software or a dedicated accounting file for each IRA-held property.

Is leverage inside a Roth IRA treated differently?

No. UDFI rules apply equally to traditional and Roth IRAs. The tax-exempt status of both account types is what triggers IRC §514. The fact that Roth distributions are tax-free in retirement does not exempt Roth IRA income from UBTI during the accumulation phase when leverage is involved.

Before Buying Leveraged IRA Real Estate

Build a full 10-year pro forma that models depreciation under ADS, the debt-financed percentage in each year, allocable deductions, net UDFI, and estimated Form 990-T tax — before you close, not after. The IRA should also maintain a dedicated cash reserve inside the account to cover debt service, capital needs, and tax filings without requiring new contributions.
