Timeline for filing with HMRC and Companies House

After the end of its financial year, your private limited company must prepare:

You need your accounts and tax return to meet deadlines for filing with Companies House and HM Revenue and Customs (HMRC).

You can also use them to work out how much Corporation Tax to pay.

The table below provides the details of deadline for different filings:

21 months after the date you registered with Companies House

File annual accounts with Companies House

9 months after your company’s financial year ends

Your accounting period for Corporation Tax is the time covered by your Company Tax Return. It’s normally the same 12 months as the company financial year covered by your annual accounts.
