Bonus depreciation on rental property in 2026: the restored 100% deduction and what qualifies

The 2026 federal bonus-depreciation rate is 100%for eligible property acquired and placed in service after January 19, 2025. That is a material change from the prior phase-down schedule. It does not mean an investor can deduct the full purchase price of a rental building.

This is educational content, not tax advice — every strategy here has real eligibility tests and audit risk. Run anything you're considering past a CPA who works with real estate investors before you act on it.

What changed: 100% was restored

The earlier law was phasing bonus depreciation down. New legislation changed that rule, and the IRS now says the additional first-year deduction is permanently 100% for eligible property acquired and placed in service after January 19, 2025. See the IRS implementation guidance.

The date boundary is essential:

Acquisition can involve binding-contract and related rules, and “placed in service” generally means ready and available for its assigned use—not simply purchased. Have a qualified tax adviser resolve borderline dates.

How depreciation works (and why bonus matters)

Residential rental buildings depreciate straight-line over 27.5 years. A full straight-line year on a $400K residential-building basis is about $14,545 before placed-in-service conventions; the first-year amount and the amount left in the building class can differ. Bonus depreciation does not apply to the 27.5-year building shell itself.

What it changes is the treatment of shorter-life property embedded in the building. If the entire $400K basis is reported in the residential-rental-building class, it stays on the 27.5-year schedule. A supportable component classification—often documented through a cost segregation study—might instead break it down as:

• $280K — 27.5-year structure (shell, framing, roof, plumbing).
• $60K — 15-year land improvements (driveway, landscaping, fencing).
• $60K — 5-year personal property (appliances, carpet, decorative lighting, blinds).

If the $120K classification is supportable and every eligibility rule is met, the restored 100% rate could produce up to a $120K additional first-year deduction. The $280K building shell remains on its applicable recovery schedule. This is an illustration, not a default allocation or tax result.

What generally qualifies

IRS Publication 946 describes qualified property as including depreciable tangible property under MACRS with a recovery period of 20 years or less, certain computer software, and several other statutory categories. Eligible used property can qualify, subject to acquisition rules. Land is not depreciable, and a residential rental building's 27.5-year recovery period generally puts the building itself outside the 20-year test.

Strategy 1: Cost segregation

A cost segregation study analyzes whether parts of a property should be classified separately from the building. A sound study documents the facts, legal classification, and allocation method; it does not make an otherwise ineligible asset qualify.

Evaluate the economics with these inputs:

• Supported allocation: how much basis can actually be classified into eligible shorter-life property.
• Timing: whether acquisition and placed-in-service dates satisfy the restored rule.
• Ability to use the deduction: basis, at-risk, passive-activity, and excess-business-loss rules can limit the current benefit.
• Exit cost: accelerated deductions reduce basis and can increase taxable gain or recapture later.
• Professional cost: study, return preparation, and possible Form 3115 work for property already in service.

There is no reliable universal price threshold. Compare the present value of tax timing after all limitations and exit effects with the cost of obtaining and defending the classification.

Strategy 2: Short-term-rental activity rules

Most rental real estate is “passive activity” under IRC §469. Passive losses can only offset passive income unless an exception and the other applicable rules are satisfied. An unused loss may be suspended rather than produce a current cash benefit.

Short stays can be treated differently for the passive-activity rules. IRS Publication 925 lists circumstances in which an activity is not treated as a rental activity, including when the average period of customer use is seven days or less. That is only the first step. The taxpayer must also satisfy a material-participation test for non-passive treatment.

• One test is more than 500 hours of participation.
• Another is more than 100 hours and at least as much participation as any other individual.
• Other tests and aggregation rules may apply to the facts.

Keep records that identify the work and time involved. Do not assume a booking platform's stay length or a large deduction alone proves non-passive treatment, and do not market the rule as an automatic way to erase salary income.

Strategy 3: Real estate professional status (REPS)

Real-estate-professional status changes how rental activities are analyzed under the passive-activity rules. It does not automatically turn every rental loss into a currently deductible non-passive loss.

Eligibility — you must meet both:

• 50% test: more than half your total personal services in trades or businesses during the year are performed in real property trades or businesses you materially participate in.
• 750-hour test: more than 750 hours/year in those real property trades or businesses.

The taxpayer must also materially participate in the rental activity or activities under the applicable grouping rules. Basis, at-risk, and other deduction limitations remain separate tests.

Common audit failures:

• Records that do not credibly substantiate the work performed and time spent.
• A job title or license alone does not establish the hours or material participation required.
• Married filing jointly — only ONE spouse needs to meet the test, but that spouse must individually meet both 50% and 750-hour real-estate-professional tests. Spousal participation can be treated differently when applying the separate material-participation rules.

Depreciation recapture — the back end

Accelerated depreciation is not evaluated in isolation. It reduces adjusted basis, which can increase gain when the asset is sold. The building and reclassified shorter-life assets can be subject to different gain-character and recapture rules.

IRS Publication 544 explains dispositions and recapture. In a cost-segregated property, some personal-property gain may be ordinary income under section 1245, while unrecaptured section 1250 gain can apply to depreciable real property. A single “25% recapture rate” does not accurately model every component.

Plan the exit before claiming the deduction:

• 1031 exchange. Roll the gain into a qualifying like-kind replacement property. Eligibility, timing, boot, and reclassified assets require transaction-specific review. Read the 1031 overview.
• Taxable sale. Model adjusted basis and the character of gain for each asset class, not just the headline sale price.
• Estate planning. Basis rules depend on how property is owned and transferred; get individualized advice rather than assuming a particular result.

Bottom-line decision tree

For property placed in service in 2026:

1. Confirm the acquisition and placed-in-service dates.
2. Separate nondepreciable land and the 27.5-year building from any shorter-life assets using supportable allocations.
3. Confirm each asset meets the qualified-property and used-property rules in Publication 946.
4. Estimate the deduction, then apply basis, at-risk, passive-activity, and other limitations.
5. Model later disposition and recapture before deciding whether acceleration improves the full investment outcome.
6. Have a real-estate tax professional review the classifications, dates, elections, and return reporting.
