Sage Payroll can send your pension data directly to Nest. You don't need to create and manually upload any files.
Make sure the pension information in Payroll matches the details you’ve set up on your Nest account.
When you process a pay run, you’re taken to the Completed Pay Run screen. If not there, select Pay runs and choose the period you wish to submit for.
NOTE: If you're submitting for the first time, enter you Nest credentials when prompted. ‘The NEST pension values were successfully submitted’
If you receive an error message, you must correct it. Once corrected, attempt the submission again.
