1 / 4

What Changed in 2022

  • Before 2022: businesses could immediately deduct R&D expenses (engineer salaries, contractor R&D, cloud-compute for development) under IRC §174.
  • Starting tax year 2022 (per 2017's Tax Cuts and Jobs Act): R&D expenses MUST be capitalized and amortized over 5 years (US R&D) or 15 years (foreign R&D).
  • The change converted what was a clean P&L deduction into a multi-year amortization schedule — dramatically increasing taxable income for unprofitable software startups.
  • Congress has repeatedly tried (TCJA Reauthorization Act, Tax Relief for American Families Act) but as of 2026 has not restored immediate expensing.
