HMRC's New Rules on P11D Payrolling Benefits

HMRC is introducing significant changes to how employers report and pay tax on employee benefits in kind (BiKs). From April 2026, payrolling benefits will become mandatory for most employers, replacing the current reliance on the P11D form.

If your business is based in Kidderminster or the surrounding areas, now is the time to start preparing for these changes. This blog reviews what the current system looks like and how it's changing.

The current process: P11D reporting

Most employers report employee benefits, such as private medical insurance, company cars and gym memberships, via a P11D form at the end of each tax year. These forms provide HMRC with a record of the benefits provided and the associated tax liability, which is then collected through the employee's tax code in future pay periods.

Employers also submit a P11D(b) form to declare and pay Class 1A National Insurance Contributions (NICs) on most benefits.

While this system works, it creates a lag between when a benefit is provided and when the tax is actually collected. It also involves a significant administrative burden at the end of the tax year, especially for employers with a growing workforce.

However, since April 2016, employers have had the option to voluntarily payroll benefits.

Introducing mandatory payrolling benefits

From 6 April 2026, the voluntary payrolling of benefits will become mandatory for most employers. This means that instead of waiting until the tax year end to report and pay tax on benefits, employers will have to include the taxable value of BiKs in their employees' pay each period, whether monthly, weekly, or otherwise.

In practical terms, tax on benefits will be deducted from the employee's pay in real time as part of the PAYE system. The need to file P11D forms for relevant BiKs will be removed, although the P11D(b) for Class 1A NICs will still be required, at least for now.

Which benefits are affected?

The majority of taxable BiKs will need to be payrolled from April 2026. These include, but are not limited to:

  • Company cars and fuel
  • Private medical insurance
  • Gym memberships or wellness packages

BiKs, which include employment related loans or living accommodation, will be introduced voluntarily from April 2026, with HMRC set to make them mandatory at a later date, yet to be confirmed.

What about Class 1A National Insurance Contributions (NICs)?

While the tax on benefits will be collected through payroll, Class 1A NICs will still be due annually, as they are now. Employers must continue to submit a P11D(b) at the end of the tax year to declare these NICs.

However, with benefits being processed through payroll, calculations for Class 1A NICs will become more streamlined, as payroll software will help track the taxable value of benefits throughout the year.

Preparing for the changes

With just over a year to go before the April 2026 deadline, employers need to begin preparing now. Here's what you should be doing:

  1. Audit your current benefits – Identify all benefits you offer and how they are currently reported.
  2. Talk to your accountant or payroll provider – Ensure your payroll system can handle payrolling benefits and comply with the upcoming rules.
  3. Update internal processes – Integrate the payrolling of benefits into your regular payroll cycle and ensure HR and finance teams, where appropriate, are aware of the changes.
  4. Communicate with staff – Explain how their payslips and tax deductions might change to avoid confusion.
  5. Stay informed – Keep an eye on HMRC updates as the transition approaches.
