As an employer providing a pension scheme to your staff, you will be responsible for uploading contributions to Smart Pension month to month and you must ensure these figures are up to date and correct as of your payroll run. 

Smart Pension requires you to provide them with a payroll file before the 1st of the following month. You can either do that via a PAPDIS file exported from your payroll software, or via a direct API link if your payroll supports it (recommended).
