Tax Law Changes Bring Permanent Bonus Depreciation for Real Estate Investors

Rental property owners have received a significant update to the United States tax code under the One Big Beautiful Bill Act, Public Law 119-21, which was signed into law on July 4, 2025. The legislation implements a permanent 100% first-year write-off for qualifying property placed in service, eliminating the previous phase-down schedule that gradually reduced the bonus depreciation allowance annually.

Under Section 168(k) of the tax code, taxpayers can deduct the full adjusted basis cost of eligible property immediately rather than spreading the deductions over multiple years. However, the legislation includes a direct trade-off: the property's basis decreases by the amount deducted, which creates potential tax liabilities during a future sale through depreciation recapture rules.

Property classification rules dictate that entire building structures do not qualify for the bonus depreciation because their recovery periods exceed the 20-year limit set by the statute. Walls and roofs remain excluded from immediate write-offs, meaning landlords typically rely on cost segregation studies to separate shorter-lived components like appliances, furniture, fixtures, and land improvements to maximize the deduction.

For investors who prefer a smaller immediate deduction, the law provides alternative options. Section 168(k)(10)(A)(i) permits taxpayers to elect a 40% deduction rate instead of the full 100% for qualifying property placed in service during the first taxable year ending after January 19, 2025. This approach allows investors to preserve deductions for future years when their marginal tax brackets might be higher.

Additionally, investors retain the option to completely opt out of bonus depreciation for specific property classes under Section 168(k)(7), subjecting those assets to standard depreciation schedules instead. Tax professionals emphasize that opting out or utilizing the 40% election requires careful planning, as reversing these choices generally demands formal consent from the Internal Revenue Service.

The financial impact of these deductions is further shaped by existing passive activity loss rules. Rental activities are classified as passive by default, meaning losses generally can only offset passive income unless the property owner meets specific real estate professional criteria by logging more than 750 hours of material participation during the year.

Tax experts advise landlords and real estate investors to consult certified public accountants before filing to navigate complex recapture regulations, installment sales rules, and passive loss limitations associated with the updated depreciation framework.
