Reporting employee benefits and expenses must be done online. What forms need to be completed? What is form P11D? What is form P11D(b)? 

This is a freeview 'At a glance' guide to forms P11D and P11D(b). 

Employers have an annual obligation to complete forms P11D in respect of each employee in receipt of taxable employment benefits or expenses. 

P11D and P11D(b) forms are used by employers to report benefits in kind to HMRC. Examples of expenses and benefits that employers need to report include:

  • company cars
  • health insurance
  • travel and entertainment expenses
  • childcare

Forms P11D must be accompanied by form P11D(b), which shows the Class 1A NIC due, and both must be filed with HMRC by 6 July.

  • Employer Class 1A NIC on taxable benefits is payable by 19 July or 22 July if paid electronically.
  • A P11D must be accompanied by an employer’s declaration to confirm the forms have been completed and filed correctly and the Class 1A NICs has been paid.
  • Penalties apply for late filing or incorrect submissions.

Since 6 April 2023, HMRC has mandated electronic filing for forms P11D and P11D(b). Filing must be completed via the PAYE online services for Employers or Agents or through recognised third party software.

  • A temporary concession was in place for the tax year 2023-24 for insolvency practitioners unable to file online. Paper forms may be submitted if accompanied by an explanatory letter.

Where are the forms for 2024/25
