You need to tell HM Revenue and Customs (HMRC) straight away if you stop employing people.
Closing your PAYE scheme
- deduct and pay any outstanding tax and National Insurance to HMRCwithin 17 days (or 14 if you’re paying by cheque)
- select the ‘Final submission because scheme ceased’ box
- put the date you closed your PAYE scheme in the ‘Date scheme ceased’ box – you can’t put a date in the future
You also need to:
- send your expenses and benefits returns
- enter a leaving date on each employee’s payroll record
- give your employees a P45 on their last day – most payroll software can produce a P45 for you or you can order them from HMRC
If you start employing anyone in the same or next tax year, you should reopen your PAYE scheme by sending an FPS with your PAYEreference.
If you temporarily stop employing staff
Your PAYE scheme continues to run if you stop employing staff for less than a whole tax year (eg if you run a seasonal business). You don’t need to give your employees a P45 if you keep them on your payroll.
