Answer

Eligibility for accelerated depreciation treatment during renovations under current U.S. tax law depends on several factors, including the type of property, the nature of the renovation, and the taxpayer’s specific circumstances. Below is a comprehensive analysis of the relevant rules and eligibility criteria as of 2025.

1. Types of Accelerated Depreciation Available During Renovations

A. Section 179 Expensing- Taxpayers may elect to expense the cost of certain qualifying property, including some improvements to nonresidential real property, up to an annual limit ($2,500,000 for 2025, phased out dollar-for-dollar above $4,000,000 in qualifying purchases).- Eligible improvements include:  - Qualified improvement property (QIP) (interior improvements to nonresidential real property, excluding enlargements, elevators/escalators, or internal structural framework)  - Roofs, HVAC, fire protection and alarm systems, and security systems placed in service after the building was first placed in service- Section 179 is not available for improvements to residential rental property or for land improvements (e.g., parking lots, landscaping).

B. Bonus Depreciation (Section 168(k))- For property acquired and placed in service after January 19, 2025, 100% bonus depreciation is available for most tangible property with a recovery period of 20 years or less, including QIP.- For property acquired before January 20, 2025, the phase-down schedule applies: 40% in 2025, 20% in 2026, and 0% in 2027 and later, unless the property qualifies under the new law for 100% expensing.- Bonus depreciation is available for both new and used property (if not previously used by the taxpayer), but not for property required to be depreciated under the Alternative Depreciation System (ADS), such as property used predominantly outside the U.S., tax-exempt use property, or certain listed property used 50% or less for business.

C. MACRS Accelerated Methods- For property not fully expensed under Section 179 or bonus depreciation, the Modified Accelerated Cost Recovery System (MACRS) allows for accelerated depreciation using the 200% or 150% declining balance method for most tangible personal property and certain land improvements.- Real property (nonresidential and residential rental) must be depreciated using the straight-line method over 39 or 27.5 years, respectively, unless it qualifies as QIP or another category eligible for accelerated treatment.

2. Who Is Eligible?

A. Taxpayers- Most taxpayers, including individuals, corporations, partnerships, and LLCs, are eligible to claim accelerated depreciation for qualifying property used in a trade or business or for the production of income.- Estates and trusts are not eligible for Section 179 expensing.

B. Property Requirements- The property must be depreciable, have a determinable useful life of more than one year, and be used in the taxpayer’s business or income-producing activity.- For Section 179 and bonus depreciation, the property must be acquired by purchase (not by gift or inheritance) and placed in service during the tax year.

C. Renovation-Specific Eligibility- Qualified Improvement Property (QIP): Interior improvements to nonresidential real property (excluding enlargements, elevators/escalators, or internal structural framework) are eligible for Section 179, bonus depreciation, and 15-year MACRS (straight-line).- Other Improvements: Roofs, HVAC, fire protection, and security systems added to nonresidential real property after the building was first placed in service are eligible for Section 179 and bonus depreciation.- Land Improvements: Items such as parking lots, sidewalks, and landscaping are generally 15-year property under MACRS and eligible for bonus depreciation, but not for Section 179.- Residential Rental Property: Improvements to residential rental property are not eligible for Section 179, but may be eligible for bonus depreciation if they are tangible property with a recovery period of 20 years or less.

D. Exclusions- Property used predominantly outside the United States, used by tax-exempt organizations (unless in a taxable unrelated trade or business), or used by governmental units (unless leased for less than six months) is not eligible for Section 179 or bonus depreciation.- Property acquired from related parties or by inheritance/gift is not eligible for Section 179 or bonus depreciation.

3. Special Considerations for Renovations

A. Cost Segregation- Taxpayers may use cost segregation studies to identify and separate components of a renovation project that qualify for shorter recovery periods and accelerated depreciation (e.g., lighting, electrical, specialty plumbing, finishes).- The IRS recognizes cost segregation as a valid method for maximizing accelerated depreciation, provided the study is well-documented and follows established legal standards.

B. Repairs vs. Capital Improvements- Expenditures that are repairs (not capital improvements) are immediately deductible as ordinary business expenses. Expenditures that are capital improvements (betterment, adaptation, or restoration) must be capitalized and depreciated.- The distinction is critical as bonus depreciation and Section 179 only apply to capitalized improvements, not to repairs.

C. De Minimis Safe Harbor- Taxpayers with an applicable financial statement may elect to expense items up to $5,000 per invoice/item; those without may expense up to $2,500 per invoice/item, provided a written capitalization policy is in place at the start of the year.

D. Materials and Supplies- Items with a cost of $200 or less, or with a useful life of 12 months or less, may be deducted as materials and supplies rather than capitalized.

E. Remodel-Refresh Safe Harbor (Retail/Restaurant)- Retail and restaurant businesses may elect the remodel-refresh safe harbor (Rev. Proc. 2015-56), allowing 75% of qualified costs to be deducted in the year incurred, with the remainder capitalized.

4. Procedural Requirements

  • Annual Elections: Section 179 and de minimis safe harbor elections must be made annually with a timely filed tax return (including extensions).
  • Method Changes: Changes in depreciation method, recovery period, or convention generally require filing Form 3115, Application for Change in Accounting Method, under the automatic change procedures in Rev. Proc. 2024-23.

5. Summary Table: Who Is Eligible for Accelerated Depreciation During Renovations?

Taxpayer Type Property Type Section 179 Bonus Depreciation MACRS Accelerated Notes
Individual, Corp, Partnership, LLC QIP (nonresidential) Yes Yes 15-year SL Must be interior, not enlargement/elevator/structural
Individual, Corp, Partnership, LLC Roofs, HVAC, fire/security (nonresidential) Yes Yes 39-year SL Only if placed in service after building first placed in service
Individual, Corp, Partnership, LLC Land Improvements No Yes 15-year 150% DB E.g., parking lots, landscaping
Individual, Corp, Partnership, LLC Residential Rental Property No Yes (if 20 years or less) 27.5-year SL
Individual, Corp, Partnership, LLC Tangible Personal Property Yes Yes 5/7-year 200% DB E.g., equipment, furniture
Estates, Trusts Any No Yes (if eligible) As above
Tax-Exempt, Government, Foreign Use Any No No ADS required

6. Conclusion

Eligibility for accelerated depreciation during renovations is broad for most U.S. taxpayers, provided the property is used in a trade or business, is not excluded by special rules (e.g., tax-exempt use, foreign use), and the improvements meet the definitions for QIP or other qualifying property. Section 179 and bonus depreciation provide significant opportunities for immediate expensing of renovation costs, especially for nonresidential real property. Cost segregation studies and careful review of capitalization policies can further maximize deductions. Method changes to correct or optimize depreciation require compliance with the automatic change procedures, typically via Form 3115.
