Bonus Depreciation After OBBBA: What Real Estate Investors Can Still Write Off in 2026
Bonus depreciation remains one of the most important tax strategies available to real estate investors in 2026.
The One Big Beautiful Bill Act dramatically reshaped depreciation planning by permanently restoring 100% bonus depreciation for qualifying property placed in service after January 19, 2025.
That change was massive for investors.
Prior law had already begun phasing bonus depreciation downward, reducing the immediate tax benefits available from property acquisitions and renovations.
OBBBA reversed that trajectory.
Now, investors may once again fully expense qualifying short-life assets in the first year.
For real estate investors, this creates significant opportunities involving:
- Cost segregation studies
- Short-term rentals
- Commercial renovations
- Multifamily acquisitions
- Qualified improvement property
- Equipment and furnishings
However, many investors misunderstand what actually qualifies for bonus depreciation.
Not every real estate asset is immediately deductible.
Understanding the post-OBBBA rules is critical for maximizing tax savings while avoiding costly mistakes.
What Is Bonus Depreciation?
Bonus depreciation allows taxpayers to immediately deduct qualifying property costs instead of depreciating them gradually over multiple years.
Under OBBBA, qualifying assets may now receive:
- 100% first-year depreciation
This means eligible assets may potentially be written off entirely in the year they are placed in service.
What Real Estate Assets Qualify?
Real estate buildings themselves usually do not qualify for bonus depreciation.
For example:
- Residential rental buildings are generally depreciated over 27.5 years
- Commercial buildings are generally depreciated over 39 years
However, certain components associated with real estate may qualify.
Examples include:
- Appliances
- Carpeting
- Flooring
- Cabinets
- Decorative lighting
- Furniture
- Landscaping
- Parking lots
- Sidewalks
- Fencing
- Security systems
- Certain electrical systems
Most qualifying assets fall into:
- 5-year property
- 7-year property
- 15-year property
This is why cost segregation studies became so important.
Why Cost Segregation Matters
Cost segregation identifies portions of a property eligible for accelerated depreciation.
Without cost segregation, many qualifying assets remain buried inside the building’s 27.5-year or 39-year depreciation schedule.
A properly prepared study may separate shorter-life components and allow immediate expensing under bonus depreciation rules.
For example:
A $1.5 million apartment building may produce:
- $300,000–$500,000 of bonus-eligible property
That can generate substantial first-year deductions.
Qualified Improvement Property (QIP)
Qualified Improvement Property remains one of the most valuable bonus depreciation categories for commercial real estate owners.
QIP generally includes certain interior improvements made to nonresidential property after the building is placed in service.
Examples may include:
- Interior renovations
- Drywall work
- Ceiling improvements
- Interior lighting
- Flooring
- Certain plumbing and electrical improvements
However, QIP generally excludes:
- Building enlargements
- Elevators
- Escalators
- Structural framework modifications
QIP is typically depreciated over 15 years and may qualify for bonus depreciation.
Used Property Rules
Bonus depreciation is not limited to new property.
Used property may qualify if:
- The taxpayer did not previously use the property
- The acquisition meets IRS requirements
This is extremely important for real estate investors because many acquisitions involve existing assets.
Placed-in-Service Requirement
One of the most misunderstood rules involves timing.
Assets must generally be:
- Placed in service during the tax year
Merely purchasing an asset is not enough.
For real estate, placed in service usually means:
- Ready and available for intended use
Construction delays, renovation timelines, and permitting issues may affect deductibility timing.
Section 179 vs Bonus Depreciation
Investors often confuse Section 179 and bonus depreciation.
Although both accelerate deductions, they operate differently.
Bonus Depreciation
- Generally automatic unless elected out
- May create losses
- Applies broadly to qualifying assets
- No taxable income limitation
Section 179
- Elective deduction
- Subject to taxable income limitations
- Phaseouts apply at higher asset purchase levels
- More limited for certain rental activities
For many real estate investors, bonus depreciation provides greater flexibility.
State Tax Conformity Issues
Not all states conform to federal bonus depreciation rules.
This creates important planning complications.
Some states:
- Disallow bonus depreciation entirely
- Require add-backs
- Use separate depreciation schedules
As a result:
- Federal deductions may differ dramatically from state deductions
- Additional compliance complexity may arise
State planning became even more important after OBBBA restored permanent 100% bonus depreciation.
Bonus Depreciation and Short-Term Rentals
Short-term rental investors became major beneficiaries of bonus depreciation planning.
When investors combine:
- The 7-day rule
- Material participation
- Cost segregation
- Bonus depreciation
They may potentially offset ordinary income with large depreciation deductions.
This strategy became especially popular among high-income taxpayers.
Depreciation Recapture
Bonus depreciation accelerates deductions.
It does not permanently eliminate taxes automatically.
When property is sold, investors may face:
- Depreciation recapture
- Section 1250 gain exposure
- Reduced capital gain treatment on portions of gain
This does not necessarily make bonus depreciation a bad strategy.
However, investors should understand the long-term implications.
Common Bonus Depreciation Mistakes
Mistake #1: Assuming Entire Buildings Qualify
Only certain components generally qualify.
Mistake #2: Skipping Cost Segregation
Without segregation analysis, many assets remain locked into long depreciation schedules.
Mistake #3: Ignoring Passive Activity Rules
Large deductions may be limited if the taxpayer cannot use passive losses.
Mistake #4: Poor Documentation
The IRS expects:
- Proper invoices
- Asset classifications
- Depreciation schedules
- Engineering support for cost segregation
Mistake #5: Failing to Coordinate Entity Structure
Entity structure may affect tax planning opportunities and liability protection.
Example Scenario
Assume:
- Investor purchases $2 million multifamily property
- Cost segregation study identifies $450,000 of bonus-eligible assets
- Investor qualifies as a real estate professional
Result:
The taxpayer may potentially deduct the $450,000 in year one under current OBBBA rules.
Depending on tax bracket, this may generate substantial federal tax savings.
Why Proactive Tax Planning Matters
Bonus depreciation is most effective when coordinated with:
- Cost segregation
- Entity structuring
- Passive activity planning
- REPS qualification
- Short-term rental rules
- Long-term exit strategies
Reactive tax preparation after year-end often misses major opportunities.
Final Thoughts
OBBBA permanently restored 100% bonus depreciation, creating major opportunities for real estate investors in 2026.
For investors using cost segregation, short-term rentals, REPS strategies, and commercial renovations, the tax savings can be substantial.
However, successful implementation requires careful planning.
The interaction between:
- Passive activity rules
- Cost segregation
- State conformity laws
- Material participation
- Future recapture
Can dramatically affect results.
The most effective investors treat tax planning as part of their investment strategy — not just year-end compliance.
