A P11D(b) form shows the value of company benefits provided to your employees, as well as the Class 1A national insurance (NI) liability on those benefits. It includes benefits that have been payrolled and/or included on P11D forms.
The information from the P11D(b) form is submitted to HMRC by 6 July following the end of the tax year. E.g., for the tax year ending 5 April 2024, the deadline is 6 July 2024. At the same time, you'll also distribute any P11Ds to your employees, and submit them to HMRC. You'll need to pay Class 1A NI due to HMRC by 22 July.
If you've submitted a P11D(b) in the past and no longer offer company benefits to your employees, then you'll need to submit a nil return.
Note: Benefits reported in a PAYE Settlement Agreement are liable to Class 1B NIC and Tax. These benefits aren't included on the P11D forms or the P11D(b) form.
P11D(b) submissions on PayFit
If you're using PayFit to calculate and process your company benefits, you can generate and submit your P11D(b) through PayFit. You'll need to confirm your preferences in your PayFit account:
From the left, choose Company settings, then Benefit settings.
Under the General settings section, click Set benefits preferences.
Answer each of the questions, then click Save.
Your submission is sent to HMRC between mid-June to 5 July 2024. The main admin on your PayFit account will receive an email confirmation and the submission status in your account will show the submission time stamp. You'll find this under the Report benefits in kind option on the left, then the Submission status tab.
Submitting a P11D(b) correction
From the tax year ending 5 April 2023, corrections to a P11D(b) must be made through HMRC's online gateway. Corrections can't be submitted through commercial payroll software.
For further information, please refer to HMRC's guidance.
