This is the latest date you plan to upload the final pension data file for a specific payroll. You’ll need to enter this date when setting up a payroll.
You can change the data in your file as many times as you need to before this date. You can’t make any changes to the pension data file (generic input file) after this date. You need to make sure all the data in your pension data file is correct and uploaded accurately, so please check your payroll and correct any errors well in advance of the processing date.
