Bonus Depreciation
Businesses also can claim a 100% bonus first year depreciation deduction for machinery and equipment bought used (with some exceptions) or new if purchased and placed in service this year, and for qualified improvement property, described above as related to the expensing deduction. The 100% write-off is permitted without any proration based on the length of time that an asset is in service during the tax year. As a result, the 100% bonus first-year write-off is available even if qualifying assets are in service for only a few days in 2020.
