How Bonus Depreciation Changed for Real Estate Owners in 2026
The bonus depreciation risks for real estate owners have shifted under the One Big Beautiful Bill Act, which restored 100% first-year depreciation for qualifying property placed in service after January 19, 2025. This guide from Information Services Unlimited breaks down what that means for your cost recovery strategy and where the traps are hiding.
What the One Big Beautiful Bill Act Means for Your Cost Recovery
The OBBBA permanently restored 100% bonus depreciation for qualifying assets, reversing the scheduled phase-down (Treasury, IRS issue guidance on the additional first year depreciation deduction amended...). Qualified improvement property, certain land improvements, and specific building components can again be fully deducted in year one when they meet the criteria.
The 100% First-Year Deduction and Its Phase-Down
The phase-down that reduced bonus depreciation by 20% annually has been eliminated for assets placed in service after January 19, 2025, a significant win for investors who acquire or improve properties in 2026.
Bonus Depreciation Recapture Rules Every Investor Should Understand
Bonus depreciation recapture rules determine how much of your accelerated deduction gets clawed back when you sell. Claiming bonus depreciation reduces the asset's adjusted basis, so the sale produces a larger gain, and the character of that gain, not just the rate, is where the real risk lives.
Section 1245 vs. Section 1250: The Character Split
Most investors hear "25% recapture" and stop there, that is only half the story.
- Section 1245 property, the personal-property components a cost segregation study reclassifies (5-, 7-, and 15-year assets like flooring, cabinetry, specialized mechanical systems, and certain land improvements). Gain attributable to depreciation on these assets is recaptured as ordinary income, taxed at your marginal rate, which can be 37% at the top bracket, not 25%.
- Section 1250 property, the building shell and its structural components (27.5- and 39-year assets). Gain attributable to depreciation here is "unrecaptured Section 1250 gain," taxed at a maximum of 25% (Topic no. 409, Capital gains and losses).
A Concrete Walk-Through
Suppose you claim $80,000 in bonus depreciation on a commercial property, $50,000 in 1245 property and $30,000 in 1250 property, and sell five years later at a gain.
- The $50,000 of 1245 recapture is taxed at your ordinary rate. At a 32% marginal rate, that is roughly $16,000 of tax.
- The $30,000 of 1250 recapture is taxed at up to 25%, roughly $7,500.
Why the Holding Period Matters So Much
Recapture does not disappear with time, but the step-up in basis at death eliminates it. Heirs receive a step-up to fair market value at the date of death, wiping out the deferred recapture. That is why the most powerful mitigation is a hold-until-death strategy, often paired with a 1031 exchange to keep deferring along the way.
- Installment sales can spread the recapture across multiple years, keeping more of it in lower brackets.
- Charitable remainder trusts can convert appreciated, recapture-heavy property into an income stream while deferring or eliminating the recapture.
- Opportunity Zone deferral, where available, can push the recognition event out, though the rules are complex and the program's status should be verified for the year of sale.
- Structuring the exit as a 1031 exchange defers the recapture into the replacement property's basis, but does not eliminate it, it compounds it.
The 1031 Interaction
A 1031 exchange does not erase recapture; it carries it forward. Depreciation claimed on the relinquished property reduces the replacement property's basis, and the deferred recapture rides along. Investors who exchange repeatedly and hold until death defer recapture indefinitely; those who exchange once and sell shortly after may find the compounded recapture erases the bonus depreciation benefit entirely.
The Bottom Line on Recapture
Recapture is not a reason to avoid bonus depreciation, it is a reason to plan the exit before claiming the deduction. The investors who benefit most know what share of their deduction is 1245 versus 1250 property, have a documented exit strategy accounting for recapture character, and have modeled the after-tax result across the full holding period.
Cost Segregation Study Benefits and the Risks They Carry
Cost segregation study benefits include accelerated depreciation on building components otherwise depreciated over 27.5 or 39 years. A study identifies assets like flooring, cabinetry, landscaping, and certain mechanical systems that qualify for 5, 7, or 15-year recovery periods.
| Strategy | First-Year Deduction | Recapture Risk | Best For |
|---|---|---|---|
| Standard depreciation | Lower | Minimal | Long-hold, low-income years |
| Cost segregation + bonus | Highest | Moderate to high | High-income years, short-hold |
| Cost segregation without bonus | Moderate | Lower | Investors avoiding recapture |
IRS Audit Triggers for Real Estate Investors Claiming Large Deductions
IRS audit triggers for real estate investors include disproportionate deductions relative to income, repeated losses, and aggressive cost segregation claims. The IRS uses data analytics to flag returns where deductions deviate significantly from industry norms.
Common triggers include:
The Quick Componentizer Report & Quick →
- Claiming bonus depreciation on assets that do not meet the qualified property definition
- Failing to attach the required election statement to your return
- Reporting rental losses that exceed passive activity limits without proper documentation
- Inconsistent treatment of the same asset class across multiple years
State Conformity Traps That Quietly Raise Your Tax Bill
State tax conformity is one of the most overlooked bonus depreciation risks, and where the federal deduction most often gets quietly clawed back. Some states fully conform, some decouple entirely, and some conform only to a frozen version of the Internal Revenue Code, never adopting the OBBBA restoration.
The Three Conformity Buckets
Most practitioners sort states into three practical buckets:
- Full conformity. The state follows federal depreciation as it changes, so the bonus deduction flows through to the state return with no add-back. Your federal and state basis stay aligned.
- Static or "frozen date" conformity. The state conforms to the IRC as of a fixed date (commonly a pre-2017 or pre-OBBBA date). Because the state code never picked up the 100% restoration, the bonus deduction is disallowed at the state level even though the state nominally "conforms." This is the bucket that trips up the most preparers.
- Full decoupling. The state explicitly requires an add-back of the federal bonus deduction and a recomputation of depreciation over the asset's regular recovery period (typically 27.5 or 39 years for real property components).
California and New York are the most commonly cited decoupled states, but several others impose add-back requirements or use a frozen conformity date. Check current-year instructions for each state where the property generates income, because conformity status changes with legislation.
The Dual-Basis Tracking Problem
When a state decouples, you are effectively running two depreciation schedules on the same asset:
- Federal basis, reduced by the full bonus deduction in year one.
- State basis, reduced only by the regular recovery-period depreciation.
What This Means for Multi-State Portfolios
A property in a fully conforming state delivers the full federal benefit with no state offset. The identical property in a decoupled state adds a state liability that can consume a meaningful share of it. A portfolio spread across several states may require three or four depreciation schedules simultaneously.
The Practical Takeaway
Model the state impact before electing bonus depreciation. For each property, identify the state's conformity bucket, compute the add-back, and compare the after-tax federal benefit against the state cost. In a decoupled, high-tax state, the net benefit may be materially smaller than the federal deduction implies, and for a short-hold investor, the state cost can erase the advantage.
When to Claim Bonus Depreciation and When to Skip It
Claiming bonus depreciation makes sense with high current income, a long-term hold, and thorough documentation of qualifying assets. Skipping it makes sense when you expect lower future income, plan a near-term sale, or own property in a non-conforming state where the state tax cost outweighs the federal benefit.
Pairing Bonus Depreciation With a 1031 Exchange
A 1031 exchange defers capital gains when you reinvest proceeds into a like-kind property. Pairing it with bonus depreciation can amplify the benefit but also compounds recapture risk: depreciation claimed on the relinquished property carries over to the replacement property's basis, and when you eventually sell without another exchange, recapture applies to the full amount.
Frequently Asked Questions
What are the downsides of bonus depreciation for real estate investors?
The main downside is recapture. When you sell a property, the IRS taxes the depreciation you claimed at ordinary income rates, up to 25% for unrecaptured Section 1250 gain. A large first-year deduction can also push you into a higher bracket or trigger the Section 461(l) excess business loss limitation, which caps how much you can write off in a single year. State-level non-conformity adds another layer of risk for investors who assume their federal deduction carries over.
Can bonus depreciation trigger an IRS audit for real estate investors?
A large bonus depreciation claim does not automatically trigger an audit, but it raises scrutiny. The IRS pays close attention to cost segregation studies that reclassify building components without proper documentation. Common red flags include claiming 100% bonus depreciation on assets that do not qualify, missing Form 3115 for a change in accounting method, and componentizing a property without a qualified engineer's report. Keeping detailed records and working with a CPA familiar with real estate reduces your exposure.
Is it ever disadvantageous to claim 100% bonus depreciation?
Yes. If your income is low or you have suspended passive activity losses, a large first-year deduction may be wasted because you cannot use it. Bonus depreciation also reduces your basis in the property, which increases the taxable gain when you sell. Investors planning a 1031 exchange should model the long-term effect before claiming. In some cases, spreading depreciation over the asset's life or using Section 179 for eligible property produces a better after-tax result.
How does the phase-down of bonus depreciation affect long-term tax liability?
The phase-down reduces the percentage you can deduct in the first year, which means more depreciation is spread across later years. That lowers your immediate write-off but also reduces the recapture hit when you sell. For investors in high-tax states, the smaller federal deduction may not offset the state tax they still owe on the full amount. Run a multi-year projection that accounts for your exit strategy before deciding whether to accelerate or defer.
