If you pay your employees monthly and your provider is Nest, you don't need to change your Tax Monthly groups.
You can continue to send pension data as normal in the new tax year.
Send pension data for the final 25/26 pay date
Send your pension data as normal for your last period of the 2025/2026 tax year. Complete this on or before 5 April 2026.
Check your groups in your pension provider portal
Next, log in to your portal and check the date ranges on your groups align to tax periods in the new tax year. If you need help with doing this, contact your pension provider.
NOTE:
If you need to check dates with a tax calendar, visit the tax week and tax month calendar article.
Dates already align
You don't need to take any further action if the dates already align to tax periods in the new tax year.
Dates don't align
If the dates don't align to tax periods, create new groups that do align and transfer your employees to them.
When you set up your new weekly, fortnightly or four weekly groups, use the following dates for the first period of the tax year:
- Weekly - 06/04/2026 to 12/04/2026
- Fortnightly - 06/04/2026 to 19/04/2026
- Four weekly - 06/04/2026 to 03/05/2026
We're unable to offer any support on using your pension provider's online portal. If you need any help with these steps, contact your provider directly.
