Don’t Miss the P11D Deadline – Here’s What Employers Need to Know

P11D submission deadline: 6th July 2025.

What is a P11D?

A P11D form is used by employers to report benefits in kind provided to employees and directors—things like:

• Company cars

• Private medical insurance

• Interest-free loans

• Living accommodation

  
  

These benefits aren’t processed through payroll but are still taxable, so HMRC requires them to be reported separately via a P11D.

What Do Employers Need to Do?

By 6th July 2025, employers must:

• Submit P11D forms to HMRC for each employee who received benefits.

• Submit the P11D(b) form to declare any Class 1A National Insurance due.

• Provide employees with a copy of their individual P11D so they are aware of what’s been reported.

  
  

Additionally, Class 1A NIC on these benefits must be paid to HMRC by 22nd July (or 19th July if paying by post).

Why It Matters

Missing the deadline or submitting incorrect information can lead to penalties and interest charges. Making sure everything is filed accurately and on time helps avoid complications and keeps your business compliant.
