Bonus Depreciation for Real Estate Investors: 2026 Guide
Bonus depreciation lets real estate investors deduct the eligible percentage of qualifying short-life property in the first year it's placed in service. Instead of depreciating those assets over their normal recovery periods, qualifying investors may accelerate the deduction.
As of 2026, the bonus depreciation rate is 100% for qualified property acquired after January 19, 2025, and placed in service on or after that date, subject to the acquisition-date and written binding contract rules. For investors who can use the loss currently, the change can move years of depreciation deductions into the acquisition year
- The rate is 100% and permanent for qualified property acquired and placed in service after January 19, 2025.
- Property placed in service Jan 1–19, 2025, or acquired before Jan 20, 2025 and placed in service later, may remain subject to prior-law phase-down rules.
- Bonus depreciation generally applies to qualified property with a recovery period of 20 years or less.
- Cost segregation commonly identifies 5-, 7-, and 15-year property that may meet the 20-year-or-less rule.
- In R.E. Cost Seg project experience, many studies identify 20%–35% of purchase price as shorter-life property. Actual results vary.
- Bonus depreciation creates deductions; passive activity, basis, and at-risk rules determine whether those deductions are usable now.
What is bonus depreciation?
To understand the "bonus," start with ordinary depreciation. Depreciation lets taxpayers recover an asset's cost through deductions over its useful life. For residential rental property, the IRS sets that life at 27.5 years. For nonresidential real property, the recovery period is 39 years.
Bonus depreciation accelerates the deduction for qualifying property. Rather than recover the cost of a qualifying 5-, 7-, or 15-year asset over its regular MACRS life, you deduct the eligible percentage — currently 100% — in Year One.
The limitation: the building itself doesn't qualify. Bonus depreciation applies to qualified property with a recovery period of 20 years or less. It does not apply to a 27.5-year residential building or 39-year nonresidential building structure. A cost segregation study identifies components that can be properly moved into shorter MACRS recovery periods.
The 2017 Tax Cuts and Jobs Act generally allowed 100% bonus depreciation for property acquired and placed in service after September 27, 2017, then scheduled the rate to phase down. The One Big Beautiful Bill Act — signed into law July 4, 2025 — reversed the phase-down, making 100% bonus depreciation permanent for qualified property acquired and placed in service after January 19, 2025.
Under the old schedule, bonus depreciation would have dropped to 20% in 2026 and 0% in 2027 for many categories. That schedule no longer applies to qualifying new acquisitions after the OBBBA effective date. On $900,000 of qualifying short-life property, the difference between 20% and 100% bonus depreciation is $720,000 of first-year deductions.
The January 19, 2025 dividing line
Properties under a written binding contract before January 20, 2025 may remain subject to the old phase-down rates. Properties acquired and placed in service after January 19, 2025 generally qualify for the full 100% on eligible components. The closing date alone does not control the analysis — a pre-January 20, 2025 binding contract can preserve prior-law rates even if closing happens later.
A professional, engineering-based cost segregation study examines a property and may reclassify components out of the 39-year or 27.5-year bucket into shorter MACRS recovery periods — when the component use, construction details, and cost documentation justify the classification.
Asset classification is fact-specific. Structural building components generally remain long-life real property, even if they are physically distinct or expensive. In R.E. Cost Seg project experience, many studies identify 20%–35% of purchase price as shorter-life property.
Rental property can qualify for bonus depreciation, but not in the way many investors first assume. The residential or commercial building itself does not qualify because it is depreciated over 27.5 or 39 years. The opportunity comes from components inside and around the building that can be properly classified as 5-, 7-, or 15-year property.
For residential rental property, that may include certain appliances, carpeting, removable floor coverings, window treatments, decorative lighting, and site improvements. For commercial rental property, it may also include qualified improvement property, plus specialized electrical, plumbing, and interior buildout components.
The result: the property stays on the proper long-life schedule, while qualifying short-life components move into bonus-eligible categories.
Land value is not depreciable
Bonus depreciation applies to depreciable property, not land. Before modeling any cost segregation benefit, allocate purchase price between land and depreciable improvements. A higher land allocation reduces the depreciable basis available for both regular and bonus depreciation.
Commercial real estate can create significant bonus depreciation opportunities. The benefit is strongest when a study identifies QIP, land improvements, or other short-life components — specialty lighting, dedicated electrical, millwork, floor coverings, parking areas, sidewalks, landscaping, and qualifying interior improvements. Common qualifying lives include 5, 7, and 15 years.
For investors acquiring office, retail, industrial, hospitality, medical, or mixed-use assets, the key question is not whether "the building" qualifies. It does not. The question is how much of the depreciable basis can be properly carved into qualifying components.
Short-term rentals deserve special attention because they can pair cost segregation with an income-offset strategy that long-term rentals often cannot access. Some STRs fall outside the passive-loss definition of "rental activity" — one common trigger is average customer use of seven days or less. If the taxpayer materially participates, the activity may be treated as non-passive.
Material participation can be established through several tests. One commonly used test is more than 100 hours and more than anyone else — but it is not the only test. This strategy is often called the "short-term rental loophole." The tax result depends on average customer use and material participation.
Consider a $3M apartment complex acquired and placed in service in 2026. Assume $600,000 is allocated to land, leaving $2.4M of depreciable basis. If a study identifies 30% of depreciable basis as qualifying short-life property, the first-year bonus deduction is $720,000.
Under the old 20% rate, the same property would have produced $144,000 in first-year bonus deductions — a $576,000 swing in deductions. The key difference in real estate is that depreciation is based on depreciable basis, not cash invested. With 25% down on a $3M property, cash invested may be about $750,000 before closing costs; a large first-year deduction can approach that amount.
That does not mean every investor gets an immediate refund. Loss usability depends on passive activity rules, basis, at-risk limitations, tax bracket, state conformity, and other facts.
Investors often confuse the two, and they can work together. Section 179 lets you immediately expense certain qualifying property, but it comes with annual dollar caps and a taxable-income limitation, and generally cannot create a loss. Bonus depreciation has no dollar cap and can generate a loss, subject to the taxpayer's other limitations.
In practice, a taxpayer may apply Section 179 first to specific assets where it makes sense, then use bonus depreciation for other qualifying property. For many real estate investors, bonus depreciation often produces the larger deduction.
Elections and planning flexibility
Bonus depreciation is generally automatic for qualified property unless the taxpayer elects out for a class of property, on a timely filed return. An investor might consider electing out when:
- Current-year losses are unusable or less valuable;
- Future tax rates are expected to be higher;
- State conformity creates unfavorable add-backs;
- Financing covenants or financial reporting considerations matter;
- Recapture planning favors slower depreciation.
Model the election before filing — the choice can materially change the timing of deductions.
By default, rental real estate is passive, so losses can generally only offset passive income; the excess carries forward. Three common paths may unlock those deductions against wages or business income.
Real Estate Professional Status (REPS)
REPS can turn rental losses from passive into non-passive. To qualify, a taxpayer generally must meet two tests: at least 750 hours in real property trades or businesses, and more than half of their personal services in those activities. One spouse generally must satisfy the REPS tests independently. When REPS applies and the taxpayer materially participates, bonus depreciation from rental real estate may offset ordinary income.
The short-term rental exception
Certain STRs can produce non-passive losses without REPS if average customer use and material participation requirements are met.
Passive income offsets
Even without REPS or STR treatment, bonus depreciation can shelter income from other passive activities. For larger portfolios, this can offset passive income from other properties.
Basis and at-risk limitations
Passive activity rules are not the only limitation. A taxpayer also needs sufficient basis and at-risk amount to deduct losses. Debt structure, ownership structure, guarantees, refinancing, and entity-level allocations can all affect deductibility. Example: if an investor has a $300,000 loss but only $200,000 at risk, the extra $100,000 may be limited.
Bonus depreciation is acceleration, not elimination, so plan the sale or exchange. When you sell, the IRS may recapture depreciation you claimed. Gain attributable to depreciation on §1245 personal property is generally recaptured as ordinary income. Real property depreciation may produce unrecaptured §1250 gain, taxed at a federal maximum rate of 25%, before state tax and other surtaxes.
A properly structured §1031 exchange can defer gain on qualifying real property. Post-TCJA §1031 generally does not apply to personal property — so a study that identifies §1245 components needs separate recapture planning. In some cases, the time value of money still makes acceleration worthwhile. Model the sale or exchange before the acquisition.
Federal rules are only half the picture. State treatment varies — some states conform to federal bonus depreciation, while others decouple or require add-backs. California, New York, and New Jersey commonly require separate state treatment. State rules can change after federal tax legislation, so verify current-year rules before filing.
If you missed allowable depreciation, Form 3115 may allow a §481(a) catch-up adjustment. The right correction depends on timing, elections, and current IRS method-change rules. Do not assume Form 3115 is always the answer — some corrections may require amended returns, and some elections cannot be fixed with a method change. Confirm the proper correction method with a qualified tax professional before filing.
A study may be worth evaluating for properties above roughly $500,000. The economics depend on study cost, property type, land allocation, tax rate, loss usability, state rules, and holding period. Based on R.E. Cost Seg project experience, studies often start around $2,800 and run to roughly $5,000 depending on size and complexity. In many cases, first-year tax savings can exceed the cost of the study.
R.E. Cost Seg uses $15,000 of expected usable bonus depreciation as a practical screening heuristic, not a filing threshold. A study is more likely to be useful when:
- The property has meaningful depreciable basis;
- The investor can use losses currently or soon;
- The holding period is long enough to justify recapture;
- State add-backs do not erase the federal benefit;
- Documentation is strong.
- Skipping component analysis. Without it, most building basis stays on the 27.5- or 39-year schedule and generally does not qualify for bonus depreciation.
- Misclassifying components. Unsupported or aggressive classifications create audit risk. Engineering-based documentation helps support the classifications.
- Ignoring loss-limitation rules. Generating deductions you can't use because of passive activity, basis, or at-risk limits. Confirm your position before you buy.
- Forgetting recapture and state add-backs. Model the full lifecycle, not just Year One.
- Assuming 1031 solves all recapture. §1031 generally applies to real property, not personal property, so §1245 components need separate planning.
- Assuming a 1031 carries full bonus eligibility. Only excess basis in a replacement property is eligible; carryover basis retains the original placed-in-service date and is not bonus eligible.
- Confirm the acquisition date, written binding contract date, and placed-in-service date.
- Allocate purchase price between land and depreciable improvements.
- Complete a cost segregation study.
- Review passive loss, basis, and at-risk limits.
- Decide whether to elect out of bonus depreciation.
- File depreciation on Form 4562.
- Coordinate state adjustments.
- Keep the study and workpapers with the tax records.
Bonus depreciation is a tax incentive that lets investors deduct a percentage of the cost of qualified property with a recovery period of 20 years or less in the first year it’s placed in service. The 2026 rate is 100% for qualified property acquired and placed in service after January 19, 2025.
100% for qualified property acquired and placed in service after January 19, 2025, under the One Big Beautiful Bill Act. Property acquired before the effective date or subject to a pre-effective-date binding contract may remain under prior-law phase-down rules.
Yes. The short-life components a cost segregation study identifies, including many 5-, 7-, and 15-year assets, may qualify for 100% bonus depreciation. Whether you can deduct the resulting loss against non-passive income depends on Real Estate Professional Status, short-term rental treatment, passive income position, basis, at-risk rules, and other facts.
Yes, but only on qualifying components, not the 27.5-year building itself. In R.E. Cost Seg project experience, many studies identify 20%–35% of purchase price as shorter-life property. Actual results depend on property type, land allocation, and documentation.
Yes, but only on qualifying short-life components. The 39-year nonresidential real property itself does not qualify. A cost segregation study identifies personal property, land improvements, and qualified improvement property that may be eligible.
Section 179 has annual dollar caps and generally cannot create a loss. Bonus depreciation has no dollar cap and can create a loss, subject to passive activity, basis, at-risk, and other limitations. Investors often use Section 179 on select assets and bonus depreciation for other qualifying property.
Yes. Bonus depreciation generally applies automatically to qualified property unless the taxpayer elects out for a class of property. Electing out may make sense when current-year deductions are less valuable, state add-backs are unfavorable, or slower depreciation better fits the investor’s plan.
Yes. On sale, gain attributable to depreciation on §1245 personal property is generally recaptured as ordinary income. Real property depreciation may produce unrecaptured §1250 gain taxed at a federal maximum rate of 25%, subject to facts, state tax, and other surtaxes.
Not always. A properly structured §1031 exchange can defer gain on qualifying real property, but post-TCJA §1031 generally does not apply to personal property. Cost-segregated §1245 components require separate recapture planning.
If you failed to claim allowable depreciation, you may be able to correct it through Form 3115 and a §481(a) adjustment, but the proper correction method depends on the facts, timing, elections, and current IRS procedures. Some cases may require amended returns.
