State Conformity to Federal Bonus Depreciation

November 28, 2023
State Conformity to Federal Bonus Depreciation

Keeping up with changing state tax laws has always been a challenging part of state tax planning for corporations, especially because states don’t consistently conform to the federal Internal Revenue Code (I.R.C.). To help simplify your corporate tax planning strategy and reduce risk, our state tax experts have compiled each state’s specific bonus depreciation rules and how they conform to federal bonus depreciation laws.

[Download the full state I.R.C. conformity chart for each state’s conformity status, key differences between state and federal bonus depreciation rules, state resources, and expert analysis.]

Bonus depreciation qualified property

Bonus depreciation allows taxpayers to deduct a specified percentage of depreciation in the year the qualifying property is placed in service.

Bonus depreciation percentage by year

Qualified property is defined as property that meets three requirements:

  1. It is MACRS property with a recovery period of 20 years or less (including qualified improvement property), depreciable (off-the-shelf) computer software, water utility property (other than rate-regulated public water utility property), qualified film production, qualified television production, qualified live theatrical production, an I.R.C. §743(b) basis adjustment in qualified property, a specified plant (defined in I.R.C. §165(k)(5)), or qualified reuse and recycling property (defined in I.R.C. §165(m)(2)).
  2. Either its original use begins with the taxpayer, or it was not used by the taxpayer or a predecessor in the five years before the taxpayer’s current placed-in-service year and it meets certain other used property acquisition requirements.
  3. It is placed in service before 2027 (or before 2028 for certain longer production period property and qualified aircraft that are acquired before 2027 or acquired pursuant to a written binding contract that became binding before 2027).
