If you don't pay your employees monthly, you may need to process a Week 53 at the end of the tax year. For the 2024/2025 tax year, this occurs if your regular weekly, fortnightly or four weekly pay date falls on 5 April 2025.

You mustn't avoid processing a week 53 pay run by setting a different process date to your regular pay date. If you've already done this, you must correct it using the steps below.

 NOTE: To find out more about week 53, visit our how to identify and process week 53 guide.

To resolve this, you need to reprocess your payroll from the week 53 payment back up to date.

Reprocess

1. Back up your data.
2. Restore a backup from the last period before the week 53 was due.
3. Check the Last Updated date. Ensure it's set to the last period before week 53 was due.
4. Click Payroll then Change Process Date.
5. Set the process date to your 05/04/2025.
6. Process the payments as normal and update records.
7. Submit an FPS as normal to provide the week 53 values to HMRC.

If you'd already processed any periods in the new tax year, you must reprocess these now using the correct regular pay date. If any employee's tax codes change for the new tax year, remember to update these.

Once complete, compare the net pay on the new payslips to what you've actually paid the employee.

You need to account for any under or overpayments you've made following the changes above. For help with this, visit our can I correct a mistake in the next pay period guide.
