Prepare Pensions Data Exchange for the new tax year

Created on  | Last modified on 


Prepare to send your pension data in the new tax year via Pensions Data Exchange (PDX) in Sage 50 Payroll.


If you pay your employees weekly, fortnightly or four weekly and use PDX, you need to make some changes each new tax year.

The date ranges on your Nest groups must align to tax periods for the new tax year.

 NOTE: If you pay your employees monthly, your Tax Monthly groups in your Nest portal are automatically aligned. You don't need to take any action for Tax Monthly groups.


Send pension data for the final 23/24 pay date

Before you proceed, send your pension data as normal for your last pay date of the 2023/2024 tax year on or before 5 April 2024.

Set up new groups on the Nest portal and transfer your employees

Next, log in to your Nest portal and check the date ranges on your groups are aligned to tax periods from the new tax year. For help with this, visit Nest support.

If the date ranges for each tax period are already aligned to tax periods in the new tax year, you don't need to take further action and can send your pension data.

If they're not aligned, you need to create new groups with the correct dates set. You can find guidance on how to set up a new group on the Nest portal from the Nest Employer help centre.

If you pay your employees weekly, it's important that when you set up your new groups in Nest, you set the pay frequency to tax weekly.

When you set up your new groups for weekly, fortnightly and four weekly, the first period of the tax year must use the following dates:

  • Weekly - 06/04/2024 to 12/04/2024
  • Fortnightly - 06/04/2024 to 19/04/2024
  • Four weekly - 06/04/2024 to 03/05/2024

Once your new group is set up, you need to transfer your employees into it. You can find guidance on how to do this from the Nest Employer help centre >

We're unable to offer any support on using the Nest online portal. If you need any advice, contact Nest directly.

Set up your new Nest group in PDX

Once your new Nest group is set up for the 24/25 tax year, you'll need to set this up in PDX.
