Sending your 'Final Submission' if you did not send it with the last FPS of the year
Article ID: 2025183 Last updated: 15 March 2021
The tax year ends 5 April 2021, and for most employers their 'Final Submission' declaration should be sent via their last Full Payment Submission (FPS) of the 2020/21 year (so the month 12, or week 52, or perhaps week 53 FPS, depending on circumstances).
If you realise that you sent your last Full Payment Submission of the year without marking it as the 'Final Submission', you can instead send your Final Submission declaration via an Employer Payment Summary.
See Section 2.2 of the End of Year Payroll Guide for for details.
