A P11D is a form submitted to HMRC reporting the value of any benefits in kind provided to employees or directors. If your company provides anything of value beyond salary, HMRC wants to know — and will tax it.
What counts as a benefit in kind?
- Company car
- Private medical or dental insurance
- Gym memberships
- Interest-free loans over £10,000
- Accommodation provided by the employer
Who must submit a P11D?
Employers must submit a P11D for each employee or director who received taxable benefits during the tax year. Deadline: 6 July each year.
P11D(b) — the employer summary
Employers must also submit a P11D(b) and pay any Class 1A National Insurance on the benefits by 22 July.
Payrolling benefits
Since April 2016, employers can payroll their benefits — collecting tax through payroll in real time. From April 2026 this becomes mandatory for most benefits.
