R&D Tax Credit Revival:
Section 174 Amortization Ends with New Congressional Fix
Congress has permanently reversed the forced amortization of domestic R&D expenses under Section 174. Starting in 2025, businesses can immediately deduct their domestic qualified research expenses, just as they could before 2022. Even more important: the fix allows for possible retroactive amendments to recover credits from tax years 2022–2024 for certain businesses.
This change offers businesses a substantial opportunity to reduce tax liabilities and unlock cash flow, but deadlines are approaching fast.
