Federal bonus depreciation in 2025 is a split-year answer: the rate was 40% for qualified property placed in service between January 1 and January 19, 2025, and 100% for property acquired and placed in service on or after January 20, 2025. The increase to 100% resulted from the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025 (Public Law 119-21), which permanently restored full first-year expensing under IRC §168(k). The cut-off date — and the distinction between acquired and placed in service, is the defining planning issue for tax year 2025 returns.
The Tax Cuts and Jobs Act of 2017 (TCJA) temporarily established 100% bonus depreciation for qualified property placed in service after September 27, 2017, through the end of 2022. Beginning in 2023, the TCJA scheduled a 20-percentage-point annual phase-down:
The OBBBA permanently restored 100% bonus depreciation effective for qualified property acquired after January 19, 2025. The acquisition date — not just the placed-in-service date — is critical:
Qualified property eligible for the restored 100% bonus depreciation includes:
Real property with a recovery period greater than 20 years (residential rental at 27.5 years, commercial at 39 years) generally does NOT qualify for standard bonus depreciation, with one significant exception noted below.
The OBBBA introduced a new temporary 100% deduction for qualified production property (QPP) — a category of real estate used in U.S. manufacturing and production activities. To qualify:
QPP expensing is a significant incentive for U.S. manufacturers and producers. Combined with 100% bonus depreciation on equipment, the full investment in a qualifying production facility (other than land) may be immediately deductible in the year placed in service.
The OBBBA also enhanced Section 179 expensing for tax years beginning after December 31, 2024. The Section 179 deduction limit increased to $2,500,000 with a phase-out beginning at $4,000,000 in total property placed in service. Key differences between the two approaches in 2025:
For the first taxable year ending after January 19, 2025 (which for calendar-year taxpayers is the 2025 tax year), the OBBBA and IRS Notice 2026-11 permit taxpayers to elect a reduced bonus rate instead of 100%:
Federal bonus depreciation enhancements do not automatically apply at the state level. Many states decouple from federal §168(k) bonus depreciation entirely or apply different rules. States including California, New York, Illinois, New Jersey, and others require a depreciation addition modification on the state return, effectively eliminating or reducing the bonus depreciation benefit for state income tax purposes. Verify your state's conformity before assuming federal and state depreciation deductions are identical.
