What Is a P11D Form and Who Needs to Submit It?

Kausik MukherjeeKausik MukherjeeJuly 29, 2025P11D Form

In the UK, employers need to report certain employee benefits and expenses using a form called P11D. But many employers don’t know how to use it and who should fill it out. They even don’t know what it includes. Let’s discuss everything about P11D in detail.

What Is a P11D Form?

A P11D form is a document used by UK employers to report expenses and benefits provided to employees and directors in addition to their salary. These are often known as “benefits in kind”. Some of such benefits are as follows:

  • Company cars
  • Private health insurance
  • Interest-free or low-interest loans
  • Living accommodation
  • Relocation expenses over £8,000
  • Gym memberships or club subscriptions

The P11D is submitted to HMRC (HM Revenue & Customs) annually to ensure that the right amount of tax and National Insurance is paid on these additional benefits.

Who Needs to Submit a P11D?

Every employer needs to submit P11D form for their employee. Employer need to submit this form if they provide extra benefits like a company car or private health insurance to their employee and if the respective employee earns £8,500 or more a year (including the value of those benefits). They also need to send the form if any expenses or benefits they provide are not tax-free or don’t fall under HMRC’s approved list of exemptions covered by HMRC’s exemptions.

What Is a P11D(b) Form?

In addition to the P11D form, employers may also need to submit a P11D(b) form. This form is used to show how much Class 1A National Insurance is owed on the benefits given to employees and to confirm that P11D forms have been completed for everyone who received taxable benefits.

What Expenses Are Exempt?

You don’t have to report all benefits or expenses. Some are tax-free and covered by HMRC’s exemptions, like:

  • Travel costs for work
  • Fees or subscriptions needed for the job
  • One mobile phone per employee
  • Parking at the workplace
  • Uniforms or safety clothing

If something is exempt, you don’t need to include it on the P11D form, but it’s important to keep clear records.

When Is the P11D Deadline?

The P11D form is due after the end of the tax year. Here are the key dates to remember:

5 April – End of the tax year

6 July – Deadline for submitting P11D and P11D(b) forms to HMRC

6 July – Deadline for giving copies to employees

22 July – Deadline for paying Class 1A National Insurance (or 19 July if paying by post)

Missing the deadline can result in penalties, so it’s important for employers to stay on top of their obligations.

How to File a P11D

There are several ways employers can submit the P11D forms:

  • Online via HMRC’s PAYE Online Service
  • Payroll software that supports P11D submissions
  • Third-party accountants or payroll providers

Using accounting professionals can reduce errors and help ensure compliance.

Penalties for Late or Incorrect Submissions

If you don’t file the P11D or P11D(b) on time, or if you file them incorrectly, HMRC may charge penalties. Here’s the details how penalties will be charged for late submission of P11D.

  • £100 per 50 employees per month for late submission of P11D(b)
  • Interest and penalties on unpaid Class 1A National Insurance
  • Penalties for providing incorrect information

Conclusion

The P11D might look like just another tax form, but it’s important. It helps make sure both employers and employees pay the right amount of tax on extra benefits, not just salary. For employers, it’s a legal requirement and helps avoid fines. For employees, it makes sure all benefits are reported correctly.
