Depreciation Life for Each Asset Class: A Simple Guide

Asset depreciation life, set by the IRS under MACRS, determines how quickly you can write off business equipment. Standard periods include 5 years for tech/cars, 7 years for office furniture, and 27.5 years for residential rentals. For 2025, the "One Big Beautiful Bill Act" has permanently restored 100% bonus depreciation for assets placed in service after January 19. Additionally, the Section 179 limit has increased to $2.5 million, allowing massive immediate write-offs.
