Key filing dates
Introduction
If you are self-employed, or a partner or director of a company, you need to be aware of key dates by which you must file annual accounts and returns with Companies House and HM Revenue & Customs (HMRC) and make payments to HMRC.
This guide tells you about key dates for:
- tax self assessment (including corporation tax)
- PAYE and National Insurance (employers)
- VAT (VAT-registered sole traders and businesses)
- Companies House annual accounts and returns - form 363 (for limited companies and limited liability partnerships use form LLP363)
There are penalties for sending accounts late to Companies House or payments and returns late to HMRC, so it is important that you make a note of key dates relevant to you or your business. There are also time extensions available with some HMRC services if you file and pay online.
