International R&D Tax Schemes 2025: A CFO’s Guide to Rates, Risks and Cross-Border Strategy
What are the leading international R&D tax schemes?
The leading 2025 international R&D tax schemes mix tax credits, super-deductions, reduced social contributions and IP/patent boxes. Headlines include the UK’s merged 20% credit, Germany’s 35% SME credit, Spain’s 25% volume plus 42% incremental, Singapore’s 68% after-tax benefit on the first S$400k, and US credits up to 13%, each with specific eligibility and interaction rules.
What are the main international R&D tax schemes in 2025?
Most countries run volume-based R&D tax credits or super-deductions, supported by IP regimes and, in some markets, reduced R&D payroll costs. The biggest differences are rates, refundability, where work can be done, subcontractor treatment and how grants interact. See more about FI Group’s Global R&D Strategy consultancy.
