The deadline for submitting the 2023-24 forms P11D, P11D(b) and P9D is 6 July 2024. These forms can be submitted using commercial software or via HMRC’s PAYE online service. HMRC no longer accepts paper P11D and P11D(b) forms. Employees must also be provided with a copy of the information relating to them on these forms by the same date. P11D forms are used to provide information to HMRC on all Benefits in Kind (BiKs), including those under the Optional Remuneration Arrangements (OpRAs) unless the employer has registered to payroll benefits.

Payrolling benefits removes the requirement to complete a P11D for the selected benefits. However, a P11D(b) is still required for Class 1A National Insurance payments regardless of whether the benefits are being reported via P11D or payrolled. The deadline for paying Class 1A NICs is 22 July 2024 (or 19 July if paying by cheque).

Where no benefits were provided from 6 April 2023 to 5 April 2024 and a form P11D(b) or P11D(b) reminder is received, employers can either submit a 'nil' return or notify HMRC online that no return is required. Employers should ensure that they complete their P11Ds accurately, including all the details of cars and loans provided.

There are penalties of £100 per 50 employees for each month or part month a P11D(b) is late. There are also penalties and interest if for late payments of Class 1A NIC.

Any tax or National Insurance due for 2023-24 under a PAYE Settlement Agreement (PSA) needs to be paid electronically to clear into HMRC’s bank account by 22 October 2024 (19 October 2024 for payments by cheque). This does not need to be reported on a P11D form.
