For qualified new assets (including software) that your business places in service in calendar year 2016, you can claim 50% first-year bonus depreciation. (Used assets don’t qualify.) This break is available for the cost of new computer systems, purchased software, machinery and equipment, and office furniture.
Additionally, 50% bonus depreciation can be claimed for qualified improvement property, which means any qualified improvement to the interior portion of a nonresidential building if the improvement is placed in service after the date the building was first placed in service. However, qualified improvement costs don’t include expenditures for the enlargement of a building, any elevator or escalator, or the internal structural framework of a building.
Important note: Under the current rules, 50% bonus depreciation will also be available for qualified assets that are placed in service in 2017. In 2018 and 2019, bonus depreciation rates will fall to 40% and 30%, respectively. The bonus depreciation program is set to expire in 2020, unless Congress revives it.
