United Kingdom: Other News in Brief: R&D, Payrolling, ISA Changes Sept 2026

The ‘Other News in Brief’ section of the 24 September 2026 Tax Matters Digest highlights three significant developments. First, the First-tier Tribunal in Environmental Services Ltd reaffirmed that R&D tax relief claims must demonstrate an advance in science or technology, not merely commercial innovation. Second, HMRC updated its mandatory payrolling guidance for benefits in kind, clarifying the treatment of globally mobile employees and Class 1A NIC obligations when payrolling is used. Third, regulations amending the Individual Savings Account (ISA) rules will introduce reduced cash ISA subscription limits and new anti-avoidance measures effective 6 April 2027, targeting structured products and temporary high-balance arrangements.

Key Takeaways

  • R&D Relief Strictness: The Tribunal’s emphasis on’scientific or technological advancement’ raises the bar for software and process improvement claims.
  • Payrolling for Mobile Employees: Employers must ensure payrolling systems correctly capture cross-border benefit valuations and NIC liabilities for internationally mobile staff.
  • ISA Anti-Avoidance Measures: The new rules target ‘bed and breakfasting’ and structured cash deposit products designed to exploit ISA limits, with penalties for non-compliant schemes.
