Summary
This guide outlines the updates to the R&D tax rules effective in 2025, specifically detailing the changes brought about by the One Big, Beautiful Bill Act. It explains that U.S. businesses can fully deduct domestic R&D expenses in the year they are incurred, eliminating the previous requirement to amortize these costs over five years. The document specifies that this change applies only to domestic research, while foreign R&D expenses remain subject to existing amortization rules. For businesses with revenues under $31 million, there is an opportunity to amend tax returns for the years 2022 through 2024 to claim full deductions for previously amortized expenses. The guide also discusses strategies for businesses exceeding this revenue threshold, allowing them to deduct any unclaimed R&D balance in 2025 or spread it across two years. It emphasizes the importance of reviewing past R&D expenditures, evaluating amendment strategies, consulting tax advisors, and assessing eligibility for the R&D tax credit to optimize tax savings.
