You can shorten an employee's pay frequency if the last tax period you processed doesn't overlap the first one on the new frequency.
This ensures the employee doesn't receive more tax-free pay for the year than they're entitled to.
Use the tables and information below to find out when and how to shorten a pay frequency.
To help you find out when you can change frequencies, use the tables below:

You can change any pay frequency before you process any payments in the new tax year.
With this option, you can start paying the employee with the new pay frequency despite any overlap.
To do this, you need to roll back the overlapping payments, and reprocess them on the new frequency.
If you already included the employee in an FPS with a later process date in this pay period, you can't submit an FPS adjustment.
However, the next FPS you submit contains the correct year to date values, including the figures for the previous periods.

Once you've changed pay frequency, check if you need to change the employee's pension scheme. For example, if you have a separate pension scheme for each frequency.
Your software calculates pension contributions using the employee's pensionable pay on their new pay frequency.
If you're unsure, contact your pension provider for advice.
