The FI Group by EPSA guide to International R&D Tax schemes in 2026
International R&D tax schemes in 2026 remain highly valuable, but the headline rate is only the starting point. CFOs need to compare the after-tax, after-grant and after-risk outcome across jurisdictions, then align project location, IP ownership, subcontracting, grant funding and evidence before major R&D spend is committed.
For UK groups operating internationally, the key question to ask is: where can our business generate a defensible, compliant and forecastable cash outcome without creating audit, transfer pricing or grant clawback issues later?
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.
Most regimes share the same commercial aim: to encourage businesses to invest more in innovation. The practical rules vary widely. CFOs should compare:
- Eligible activities: what qualifies as R&D in that country
- Eligible costs: staff, subcontractors, consumables, cloud, software, assets and overheads
- Location rules: where the work, people and costs must sit
- Refundability: whether the incentive creates cash, offsets tax, or carries forward
- Grant interaction: whether public funding reduces the claim base
- IP and beneficiary rules: who owns, controls and benefits from the resulting technology
