What’s Changing and Why
From 6 April 2026, the UK is implementing major compliance reforms for employers involving:
- the real‐time payroll reporting of most BiKs (Benefits in Kind) for Income Tax and Class 1A NICs, via payroll software. (gov.uk)
- Umbrella company supply chains being made accountable: agencies and end clients may become responsible if an umbrella company fails to operate PAYE correctly. (gov.uk)
These reforms stem from Budget 2025 initiatives aimed at closing compliance gaps and simplifying payroll tax administration. Employers and agencies need to plan ahead to manage risk.
Key Impacts for Employers and Agencies
- Payroll software must be updated to support real-time BiK reporting. If BiKs include accommodation, loans or third-party invoiced services, delays or estimates may require adjustment at end of year. (gov.uk)
- Umbrella company clients and agencies will need to perform due diligence to ensure umbrella companies in their supply chains are properly accounting for tax and NICs. Liability can shift up. (gov.uk)
Actionable Steps for Compliance
- Audit current BiKs setup: By early 2026, list all BiKs you provide (e.g. company car, health insurance, accommodation). Assess which are already payroll enumerated and which aren’t.
- Upgrade software or workflows: Ensure your payroll software is compliant with new reporting requirements. If needed, work with vendors to test Full Payment Submission channels.
- Review contract terms with umbrella companies: Insert clauses that ensure umbrella companies comply and indemnify if they fail. Document evidence.
- Training: HR, finance, operations teams should be trained by end of 2025 on new BiK reporting, student loan plan types (see Agent Update), and new thresholds.
- Communicate to employees: When their BiKs change tax treatment, employees should understand what will be reported and when, and how it affects their net pay.
Practical Example
Example-Employer Ltd. provides accommodation and health insurance and currently reports these via P11D forms. From 6 April 2026, the accommodation will need real-time payroll reporting; if third-party invoices are resolved late, an estimate process, followed by reconciliation at year-end, will be required. If one of their contractors works via an umbrella company which fails to operate PAYE on their pay, Example-Employer Ltd. might be liable for the tax and NICs shortfall.
Employee Student Loan Plan Changes (Complementary)
Also effective 6 April 2026: Student Loan Plan 5 is introduced for new borrowers; thresholds for all plan types also updated. Employers must use new plan type codes when calculating loan repayments through payroll. (gov.uk)
Risk Management
- Software integrity: untested systems may misreport or delay BiK values; errors carry financial and reputational risk.
- Supply-chain oversight: Umbrella liabilities can arise unexpectedly—ensure clarity in contracts and maintain documentation.
- Monitoring legislation updates: Some secondary legislation for BiKs exceptions (e.g. loans, accommodation) will have phased implementation. Stay current.
Summary
These compliance changes mark a shift to more real-time, higher accountability payroll tax administration. Employers and umbrella companies must adapt systems, contracts, and reporting practices before 6 April 2026 to meet requirements and avoid potential liabilities. Proper early planning will reduce risk and smooth transition.
