What is a P11D form?
P11D is the annual return employers use to report taxable expenses and benefits in kind provided to employees and directors (e.g., private medical insurance, beneficial loans, company cars), unless the benefits are pay rolled. Abolition of the old £8,500 “higher-paid” threshold means the earnings test no longer applies (changed from April 2016).
Who files a P11D?
The employer files P11D for each employee/director who received a reportable benefit during the tax year, except where the employer has registered to payroll the benefit (in which case no P11D is required for those pay rolled items, but a P11D(b) is still needed for Class 1A NIC).
When is it due?
- 6 July after the tax year: submit forms P11D and P11D(b).
- 22 July (electronic) / 19 July (cheque): pay Class 1A NIC shown on P11D(b).
How to file
From 6 April 2023, HMRC no longer accepts paper P11D/P11D(b) (including amendments) — use HMRC’s online services or compatible software.
What to include on a P11D?
Report taxable benefits such as company cars/fuel, private medical/dental insurance, beneficial loans, assets made available to employees, certain relocation/credit-card expenses, and other non-exempt items. (If you payroll a benefit, you don’t report it on the individual’s P11D, but you still complete the P11D(b).)
Penalties
- Late P11D(b): automatic penalty of £100 per 50 employees (or part thereof) for each month/part-month late.
- Late Class 1A NIC payment: interest and further penalties can apply.
- Inaccuracies: HMRC may charge penalties depending on behaviour (careless/deliberate/concealed).
Payrolling benefits (now & what’s coming)
Voluntary payrolling is available now — register before the tax year starts, then include the cash-equivalent of benefits in the employee’s pay so tax is collected in real time (you’ll still submit the P11D(b)). From 6 April 2027 payrolling becomes mandatory for most benefits.
