1) Send the final Full Payment Submission (FPS) on or before your employees’ last payday of the tax year (which ends on 5 April). Put ‘Yes’ in the ‘Final submission for year’ field in your payroll software.
If you forgot to select 'Yes' in the final FPS, you should send your final report in an EPS instead of an FPS. An EPS has to be sent also if you didn’t pay anyone in the final pay period of the tax year.
If you’re late sending your final report - Send an FPS if it’s 19 April or before. You would be charged a penalty for late filing.
2) Prepare for the new tax year by updating the new tax codes for all employees in the payroll software. If there are lots of tax code notices, it may be faster to use HMRC’s PAYE Desktop Viewer.
3) Follow instructions from your payroll provider and update the payroll software, so that the new rates and thresholds are automatically captured for use in the new tax year
4) Issue P60 to all employees on your payroll who are working for you on the last day of the tax year (5 April). The P60 summarizes their total pay and deductions for the year. P60s must be issued by 31st May.
