If you’ve already submitted your P11Ds in UK Payroll and spot an error, corrections can’t be made in UK Payroll, you’ll need to update them directly with HMRC.
Once a P11D has been submitted through UK Payroll, the submission is final in the system. UK Payroll and HMRC do not support amendments to P11Ds after submission. Any corrections must be completed through HMRC’s online portal.
You can report and correct expenses and benefits directly with HMRC here
Before you submit your P11Ds, it is therefore important to double-check the data to avoid the need for corrections later. As a payroll processor, you can review everything in advance:
- Go to Reports
- Select HMRC documents
- Open P11Ds and P11D(b)
From here, you can review a draft version of your P11D submission before sending it to HMRC. This helps you catch discrepancies early.
In this area, you can:
- Download a CSV file with each employee’s reportable P11D values
- Download individual employee P11D documents for review prior to submission
For Class 1A National Insurance Contributions, the same section provides a clear summary of:
- The total benefits liable to Class 1A National Insurance Contributions
- The total Class 1A NICs payable on those benefits
You can also download a P11D(b) report as a CSV file, which details the Class 1A National Insurance Contributions due for each individual employee and their benefits.
Keep in mind that payment of Class 1A National Insurance Contributions must be made directly to HMRC. If you’re not paying by post, the deadline is 22 July. UK Payroll does not make Class 1A NIC payments on your behalf, so you’ll need to arrange payment with HMRC separately.
Catching issues before submission will save you time and additional work with HMRC, so we strongly recommend reviewing all draft P11D and P11D(b) reports carefully before filing.
