Can You Take Bonus Depreciation on Rental Property?

Yes, you can take bonus depreciation on qualifying rental-property components, but not on the entire building or the land. Eligible 5-, 7-, and 15-year assets can receive the Section 168(k) special depreciation allowance when the acquisition, placed-in-service, used-property, MACRS, and election requirements are met. The residential or commercial building remains 27.5- or 39-year property, and a valid deduction may still be suspended by loss-limitation rules.

This guide explains exactly what qualifies, what does not, how cost segregation supports the classification, where the deduction appears on the return, and whether the resulting loss is actually usable.

Rental Property Bonus Depreciation: The Seven-Gate Test

A cost-segregation report can identify shorter-life components, but it does not automatically make every reported dollar deductible. Work through these seven gates in order.

1. Ownership and income-producing use. The taxpayer claiming depreciation must own the asset and use it in a taxable rental or business activity. Personal-use portions do not qualify.
2. Eligible asset class. Tangible MACRS property with a recovery period of 20 years or less can qualify. The 27.5-year residential building, 39-year nonresidential building, and raw land do not.
3. Acquisition timing. Current 100% treatment generally applies to eligible property acquired and placed in service after January 19, 2025. Earlier acquisitions can fall under transition rules even when placed in service later.
4. New or eligible used property. New assets can qualify, and certain used assets can qualify. Prior use by the taxpayer, related-party purchases, carryover-basis transactions, and other acquisition facts can block used-property eligibility.
5. Placed-in-service status. The property must be ready and available for its assigned rental function. A closing date, invoice date, or furniture delivery date is not conclusive when substantial work remains.
6. Method and election review. Property required to use ADS does not receive the special allowance. A timely election out applies by class of property, not asset by asset.
7. Loss usability. Basis, at-risk, passive-activity, and excess-business-loss limits are applied after the depreciation is computed. They can defer the tax benefit without changing the underlying depreciation schedule.

Which Rental Property Costs Can Receive Bonus Depreciation?

The classification must be supported. Separately purchased furniture and appliances may be obvious from invoices, while shorter-life components embedded in an acquired building generally require engineering, plans, measurements, cost data, and tax authority. A cost-segregation study should reconcile every reclassified dollar to the property's total depreciable basis.

A Deduction Is Not the Same as a Currently Usable Loss

Form 4562 may correctly produce a large depreciation deduction while the individual return receives little or no immediate tax reduction. The return applies limitation rules after computing depreciation:

• Tax basis. A pass-through owner generally cannot deduct losses beyond adjusted basis.
• At-risk limitation. Nonrecourse financing and protected amounts can restrict the deductible loss.
• Passive-activity rules. Long-term rental losses are generally passive unless an exception and the required participation tests are met. Passive losses can be suspended on Form 8582.
• Excess business loss limitation. Even a nonpassive loss may be limited under Section 461(l), with the disallowed amount carried under the applicable rules.
• State conformity. A state can require an addition modification and a separate future depreciation schedule even when the federal deduction is allowed.

Three Worked Rental Scenarios

Scenario 1: Long-term rental with no passive income

A cost-segregation study identifies $180,000 of eligible short-life assets and the federal return claims the special allowance. The owner does not qualify for real estate professional treatment and has no other passive income. The deduction is still recorded in the asset schedule, but the resulting passive loss may be suspended on Form 8582 instead of reducing salary income currently. The study can still have value, but it is not an immediate dollar-for-dollar W-2 offset.

Scenario 2: Short-term rental that is nonrental for Section 469

The average customer-use period and services facts place the activity outside the rental-activity definition under the temporary Section 469 regulations. The owner also satisfies a material-participation test with contemporaneous records. The bonus-driven loss may therefore be nonpassive, subject to basis, at-risk, excess-business-loss, and other rules. The short average stay alone is not enough; material participation is a separate requirement.

Scenario 3: Partnership-owned multifamily property

The partnership owns the building, commissions the study, records the reclassified assets, and completes Form 4562 and Form 8825. The entity-level result flows to the partners on Schedule K-1. Each partner then applies personal basis, at-risk, and passive-loss limits. Partners should not recreate the partnership's appliances, carpeting, or site improvements on their individual depreciation schedules.

How to Report the Deduction

For property placed in service during the current year, the fixed-asset schedule records each qualifying asset, basis, recovery class, method, convention, and placed-in-service date. Form 4562 reports the special depreciation allowance in Part II and the remaining MACRS depreciation in Part III. The total then flows to Schedule E, Form 8825, Schedule C, or the owning entity return, depending on who owns and uses the property.

For a study completed after filed returns, determine whether the prior treatment is a one-year error or an established accounting method. A one-year error may require an amended return. An eligible change from an impermissible depreciation method generally uses Form 3115 and a Section 481(a) adjustment. The current automatic-change guidance, scope limits, timing, and duplicate-copy procedure must be checked for the year of change.

Documents to Gather Before Filing

• Closing statement, purchase contract, appraisal, and support for the land allocation.
• Final cost-segregation report, component detail, photographs, and depreciation schedules.
• Invoices for furniture, appliances, improvements, and other separately purchased assets.
• Placed-in-service evidence, rental listings, readiness records, and personal-use logs.
• Prior federal and state depreciation schedules, Forms 4562 and 8582, and any prior Form 3115.
• Debt documents, entity ownership records, K-1s, participation logs, and state conformity workpapers.

Common Bonus Depreciation Filing Failures

• Claiming bonus depreciation on the 27.5- or 39-year building rather than qualifying components.
• Applying the current rate based on the study date instead of the acquisition and placed-in-service facts.
• Using a rule-of-thumb percentage without reconciling the study to depreciable basis.
• Assuming that creating a tax loss means it can offset W-2 or business income immediately.
• Calling a short-term rental nonpassive without separately testing the activity definition and material participation.
• Taking a second deduction because reclassified basis was not removed from the original building asset.
• Ignoring an ADS requirement, an election out, state decoupling, or prior depreciation.

Before claiming the deduction: confirm what qualifies, who owns the assets, when they were placed in service, whether the loss is usable, and how the state return differs. Book a Return Review Call for a rental depreciation implementation review.

What Is Bonus Depreciation? (IRC Sec. 168(k))

Bonus depreciation is a federal tax provision that allows you to deduct the full cost of qualifying property in the year it is placed in service, rather than spreading that deduction over the asset's normal recovery period. Under IRC Sec. 168(k), this applies to tangible personal property and certain improvements with a Modified Accelerated Cost Recovery System (MACRS) recovery period of 20 years or less.

In practical terms: if a cost segregation study identifies $150,000 worth of 5-year, 7-year, and 15-year components inside your rental property, you can deduct the entire $150,000 in Year 1 instead of spreading it out over those recovery periods.

The History: From TCJA to the OBBBA

The Tax Cuts and Jobs Act (TCJA) of 2017 introduced 100% bonus depreciation for property placed in service after September 27, 2017 and before January 1, 2023. Congress included a scheduled phasedown:

• 2023: 80% bonus depreciation
• 2024: 60% bonus depreciation
• 2025: 40% bonus depreciation
• 2026: 20% bonus depreciation (under the old schedule)
• 2027 and beyond: 0% bonus depreciation (under the old schedule)

That phasedown created uncertainty for investors. Many delayed acquisitions or rushed closings to capture higher percentages. The OBBBA eliminated this problem entirely.

OBBBA: 100% Bonus Depreciation Is Permanent

The One Big Beautiful Bill Act restored 100% first-year bonus depreciation with no scheduled phasedown or sunset. The restored rate generally applies to qualified property acquired and placed in service after January 19, 2025. It does not retroactively increase the bonus percentage for property acquired and placed in service in 2023 or 2024.

For real estate investors, this is the green light to move aggressively on cost segregation studies and bonus depreciation planning.

What Qualifies for Bonus Depreciation

Under IRC Sec. 168(k)(2), property must meet these requirements to qualify:

1. MACRS recovery period of 20 years or less. This includes 5-year property (appliances, carpeting, vinyl flooring, cabinetry), 7-year property (furniture, office equipment, certain fixtures), and 15-year property (land improvements such as driveways, sidewalks, landscaping, fencing, parking lots, and exterior lighting).
2. Original use begins with the taxpayer, OR the property is acquired used and meets the "used property" rules. The TCJA expanded bonus depreciation to cover used property for the first time, as long as the taxpayer had not previously used the property and it was not acquired from a related party.
3. Placed in service during the tax year. The property must actually be in use or ready for its intended purpose, not just purchased.

What Does NOT Qualify

Two major categories of rental property costs are excluded from bonus depreciation:

• The building structure itself. Residential rental buildings carry a 27.5-year recovery period under IRC Sec. 168(c). Nonresidential real property (including short-term rentals classified under IRC Sec. 168(e)(2)(B)) carries a 39-year recovery period. Both exceed the 20-year cutoff.
• Land. Land is not depreciable at all under IRC Sec. 167(a) because it does not have a determinable useful life.

This is exactly why cost segregation matters. Without a study, most acquisition basis may remain in a single 27.5- or 39-year building asset even though separately purchased furniture and appliances can already have shorter lives. A defensible study identifies and values eligible shorter-life components embedded in the acquired real estate; the result depends on the actual property rather than a fixed percentage.

How Bonus Depreciation and Cost Segregation Work Together

Cost segregation and bonus depreciation are two separate tax provisions that create massive value when combined:

1. Cost segregation (IRC Sec. 1245 and 1250) identifies and reclassifies building components from the default 27.5 or 39 year recovery period into shorter asset classes: 5-year, 7-year, and 15-year property.
2. Bonus depreciation (IRC Sec. 168(k)) then deducts 100% of those reclassified components in Year 1.

Without cost segregation, bonus depreciation has nothing to apply to (because the building itself does not qualify). Without bonus depreciation, cost segregation still accelerates deductions, but over 5, 7, and 15 years rather than all at once.

Real Example: $500,000 Rental Property

Consider a single-family rental purchased for $500,000 (excluding land value of $75,000, leaving a depreciable basis of $425,000):

The investor with cost segregation and bonus depreciation records $158,795 of Year 1 depreciation, compared with $15,454 in this simplified straight-line illustration. At a 37% marginal rate, the incremental deduction has a potential federal value of about $53,000 only if the loss is currently usable. Passive-loss and other limitations can defer some or all of that benefit.

Scaling Up: $1.2 Million Property

For a larger property purchased at $1,200,000 (land: $200,000, depreciable basis: $1,000,000), assume a study supports $350,000 of bonus-eligible components. At a 37% marginal rate, that deduction has a potential federal value of $129,500 if it is currently usable. The actual allocation and cash-tax result require property-specific engineering and a limitation review.

Bonus Depreciation vs. Section 179: Know the Difference

Investors sometimes confuse bonus depreciation with Section 179 expensing. Both allow accelerated deductions, but the differences matter:

For most rental property investors running cost segregation studies, IRC Sec. 168(k) bonus depreciation is the primary tool. Section 179 serves as a complement in specific situations but rarely replaces bonus for large-scale real estate.

Electing Out of Bonus Depreciation: IRC Sec. 168(k)(7)

Not every investor wants to take all their depreciation in Year 1. IRC Sec. 168(k)(7) allows you to elect out of bonus depreciation for any class of property placed in service during the tax year. The election is made on a class-by-class basis (all 5-year property, all 7-year property, or all 15-year property).

You might elect out if:

• You had a low-income year and expect significantly higher income in future years
• You already have enough losses from other sources to offset your current income
• You want to spread depreciation across multiple years for steadier tax planning
• You are concerned about depreciation recapture under IRC Sec. 1245 or 1250 if you plan to sell soon

This election is generally made on a timely filed return, including extensions, for the year the property is placed in service and applies to the selected class of property. Revocation generally requires IRS consent, subject to the current regulations and any applicable relief procedure.

Placed-in-Service Rules

Property must be "placed in service" during the tax year to claim bonus depreciation. Under Treasury Regulation Sec. 1.167(a)-11(e)(1)(i), property is placed in service when it is in a condition or state of readiness and availability for its specifically assigned function. For rental property, this generally means the property is ready to be rented, not merely purchased.

Key timing considerations:

• Closings near year-end: If you close on December 15 and the property is move-in ready, it is placed in service in that tax year. If it needs significant renovation, it may not be placed in service until the following year.
• Renovations and improvements: Each improvement component has its own placed-in-service date. A kitchen renovation completed in March is placed in service in March, even if you bought the property in January.
• Furnished short-term rentals: Furniture, appliances, and fixtures are placed in service when the property is listed and available for guests, not when you purchase the items.

The STR Loophole Connection

Bonus depreciation becomes dramatically more powerful when paired with the short-term rental tax loophole. Here is why:

Under IRC Sec. 469, rental activities are generally passive. Passive losses can only offset passive income, not W-2 wages or business income. However, short-term rentals with an average rental period of 7 days or less are not treated as "rental activities" for purposes of IRC Sec. 469. If the STR owner also materially participates in the activity, the resulting losses are non-passive.

That means a cost-segregation study can identify eligible components and bonus depreciation can create a large Year 1 loss. If the activity falls outside the rental-activity definition and the owner materially participates, the loss may be nonpassive. Basis, at-risk, excess-business-loss, business-use, and other limits still apply, so the result should be modeled on the actual return before treating the projected deduction as cash-tax savings.

Already Own Property? Determine the Correct Catch-Up Procedure

If you purchased a rental property in a prior year and never performed a cost-segregation study, you may still have a correction path. When the filed-return history establishes an impermissible depreciation method and the taxpayer qualifies for the applicable automatic change, Form 3115 can claim a Section 481(a) catch-up adjustment in the year of change. A one-year error may instead require an amended return, and current scope, timing, and filing requirements must be checked.

This catch-up provision can be even more valuable than doing cost segregation at the time of purchase, because you capture multiple years of missed deductions in one lump sum.

Key Takeaways

• 100% bonus depreciation is permanent under the OBBBA. No phasedown, no sunset.
• Only property with a MACRS recovery period of 20 years or less qualifies (5, 7, and 15 year components).
• Cost segregation identifies shorter-life components embedded in an acquired building; separately purchased short-life assets can be classified from their own invoices.
• Bonus depreciation has no dollar cap and can create losses, unlike Section 179.
• An STR loss may be nonpassive only after the activity-definition and material-participation tests are both satisfied; other limits still apply.
• Already own property? Analyze whether Form 3115 or an amended return is the correct correction procedure.
