Tax reform legislation includes changes that affect a business’ bottom line. One of these changes allows businesses to write off most depreciable business assets in the year they place them in service.

Here are some facts about this deduction:

  • The 100-percent depreciation deduction generally applies to depreciable business assets and certain other property.
  • Machinery, equipment, computers, appliances and furniture generally qualify.
  • The deduction is retroactive for qualifying property acquired and placed in service after September 27, 2017.
  • Taxpayers who elect out of the 100-percent depreciation deduction must do so on a timely filed return.
