What is a P11D form?

Full answer

A P11D (Expenses and Benefits) is an annual return submitted by employers to HMRC by **6 July** after the end of the tax year (so by 6 July 2026 for the 2025/26 tax year). It reports the value of non-cash benefits provided to employees and directors. **Common benefits reported on a P11D:** - Company car (taxable value based on CO₂ emissions and list price) - Private medical insurance / dental plans - Living accommodation provided by the employer - Interest-free or low-interest loans (above £10,000) - Gym membership or other personal benefits - School fees paid by the employer - Season ticket loans **How you are taxed:** The P11D value is added to your income for the year. HMRC adjusts your PAYE tax code to collect the additional income tax owed over the following year. If you complete a Self Assessment return, declare BIK income there. **Employer Class 1A NI:** Your employer pays **Class 1A NI at 15%** on the total taxable BIK value — due by 22 July (electronic payment) after the P11D submission. This is the employer's cost, not yours. **Trivial benefits exemption:** Small benefits costing the employer **£50 or less per item** (e.g. birthday gifts, vouchers not exchangeable for cash) are exempt from P11D reporting provided they are genuinely trivial and not cash or cash vouchers. **Payrolling benefits:** As an alternative to annual P11D filing, employers can register to **payroll benefits in kind** — the BIK value is added to your salary monthly and taxed in real time through PAYE. This avoids the end-of-year P11D process. From **April 2026**, payrolling of most BIKs became mandatory for new BIKs. **P11D(b):** The form used by the employer to declare the total Class 1A NI liability across all P11Ds — separate from the individual P11D forms.
