Bonus Depreciation for Commercial Real Estate in 2026: Complete Guide + Examples

Quick Takeaways

• 100% bonus depreciation is law through 2026 — the One Big Beautiful Bill Act (OBBBA) permanently restored full deduction for qualifying property acquired after January 19, 2025
• You can deduct the entire cost in Year 1 — eligible assets placed in service in 2026 qualify for the full deduction, not spread over 5–39 years
• Commercial real estate qualifies — office buildings, retail, industrial, apartment complexes, and certain improvements all eligible
• It stacks with cost segregation — combine bonus depreciation with cost segregation studies to accelerate write-offs on real property improvements
• Timing matters — property must be "placed in service" (ready for business use) in 2026 to qualify
• State rules vary — 13 states don't conform to federal bonus depreciation; verify your state's rules before counting on the deduction

Why 2026 Is Your Last Full-Depreciation Window

The One Big Beautiful Bill Act, signed into law on January 23, 2025, permanently restored 100% bonus depreciation for qualified property. Before this change, bonus depreciation was phasing down:

• 2024: 60% deduction
• 2025–2026: 80% and 60% (under the old schedule)
• 2027+: Phase-down to 0% (if not extended)

The new law eliminates the phase-down entirely, meaning 100% bonus depreciation is now permanent law—not a temporary incentive. For commercial real estate investors, this is a rare opportunity to write off the full cost of qualifying assets in the year they're purchased and placed in service.

Why This Matters for Your Bottom Line

A $2 million commercial office building with $400,000 in qualifying personal property (HVAC, fixtures, equipment) can now be deducted in full in Year 1, rather than spread over 27.5 to 39 years. On a 25% combined federal and state tax rate, that's approximately $100,000 in Year 1 tax savings—cash that stays in your business instead of going to the IRS.

This window will likely close. Congress has extended bonus depreciation 17 times since 2001, and it's never been permanent before. If you're planning capital expenditures, 2026 is the year to accelerate them.

Understanding Bonus Depreciation

Bonus depreciation is a tax deduction that allows you to write off a large portion (or all) of the cost of certain assets in the year they are purchased and placed in service—rather than depreciating them over their useful life.

The Two Types of Depreciation

MACRS Depreciation (regular depreciation): Assets are deducted over their useful life:

• Commercial office/retail/industrial buildings: 39 years
• Apartment buildings (multi-family residential): 27.5 years
• Single-family rental homes: 27.5 years
• Personal property/equipment/fixtures: 5–15 years
• Certain improvements (flooring, walls, doors, parking lot repaving, landscaping): 15 years

Bonus Depreciation (2026): 100% of the cost can be deducted in Year 1, as long as the property qualifies and is placed in service in 2026. This is permanent law as of the One Big Beautiful Bill Act (January 2025).

What Property Qualifies for Bonus Depreciation?

Not all commercial real estate qualifies. The rules are specific.

Eligible Property

Qualified real property placed in service after January 19, 2025:

1. Qualified Improvement Property (QIP)
   • Interior improvements to nonresidential real property (offices, retail, warehouses)
   • Includes: roof coverings, HVAC systems, plumbing upgrades, electrical upgrades, flooring, non-load-bearing walls, doors, lighting fixtures, signage, interior paint/finishes
   • Does NOT include: land, structural components (foundation, load-bearing exterior walls), building expansions
2. Qualified Leasehold Property
   • Improvements to leased commercial property (tenant improvements)
   • Must be nonresidential real property
3. Personal Property Fixtures and Equipment
   • HVAC systems, electrical systems, plumbing, security systems
   • Furniture, fixtures, equipment (FF&E)
   • Machinery and equipment used in the business
4. Land Improvements
   • Sidewalks and pavement, parking lot repaving, landscaping improvements
   • Drainage systems and retention ponds, fencing, gates, exterior lighting

Real-World Example: $2M Commercial Office Building

Item	Amount	Bonus Deduction	Benefit (at 25% tax rate)
HVAC System	$150,000	$150,000	$37,500
Electrical/Plumbing	$120,000	$120,000	$30,000
Interior Improvements (QIP)	$300,000	$300,000	$75,000
Furniture/Equipment	$80,000	$80,000	$20,000
Total Bonus Depreciation	$650,000	$650,000	$162,500

Year 1 tax savings: ~$162,500

Without bonus depreciation, you'd claim only ~$180,769 in Year 1 deductions under regular MACRS (saving ~$45,192). The difference is clear: bonus depreciation saves you $117,308 in Year 1 by accelerating deductions.

Next Steps: Maximize Your 2026 Bonus Depreciation

1. Inventory your 2026 acquisitions — List all commercial real estate purchases planned for 2026, including renovations and equipment.
2. Allocate purchase price — Work with a qualified tax advisor to separate land (non-depreciable), building (39-year or 27.5-year), improvements (5–15 year), and equipment (bonus-eligible).
3. Consider a cost segregation study (CRITICAL) — For properties over $500k, invest in a professional study ($2,500–$5,000) to identify improvements and equipment that qualify for bonus depreciation. Without it, you might claim bonus depreciation only on obvious equipment, missing $100k–$300k+ in building improvements that also qualify.
4. Verify state conformity — If you're in Illinois, Iowa, Kansas, Louisiana, Maine, Mississippi, Missouri, New Hampshire, New Jersey, New York, Ohio, Oregon, or Texas, verify your state's bonus depreciation rules before claiming.
5. Hit the "placed in service" deadline — Acquisitions and renovations must be complete and operational by December 31, 2026 to claim Year 1 bonus depreciation.

FAQ: Bonus Depreciation for Commercial Real Estate

Q: If I buy a property in 2026, can I claim bonus depreciation?

A: Yes, if the property qualifies and is placed in service in 2026. Property must be acquired after January 19, 2025, and actually placed in service (ready for business use) by December 31 of the year claimed.

Q: Does bonus depreciation apply to used/existing buildings?

A: Bonus depreciation generally applies only to newly acquired property. However, if you buy an existing building and make capital improvements (renovation, new HVAC, new roof), those improvements qualify for bonus depreciation.

Q: Can I claim bonus depreciation on a property I bought before 2025?

A: Only on capital improvements made after January 19, 2025. If you bought the building in 2024, improvements you make in 2026 can claim bonus depreciation; the original building cannot.

Q: What if my business operates at a loss? Can I still claim bonus depreciation?

A: Yes. Bonus depreciation can create or increase a business loss. However, for passive real estate investors (not actively involved in management), passive activity loss limitations may limit how much loss you can deduct in any single year.
