What Is the Company Accounts Deadline?

The company accounts deadline refers to the latest date by which a company must submit its annual accounts to Companies House. This deadline depends on whether it’s your first year of incorporation or a subsequent financial year.

First Company Accounts Deadline

For newly incorporated companies:

  • You must file your first accounts within 21 months of incorporation.
  • Example: If your company was formed on 1 January 2024, your company accounts deadline would be 1 October 2025.

Annual Company Accounts Deadline (after the first year)

For subsequent years:

  • You must file your annual accounts within 9 months of your financial year-end.
  • Example: If your financial year ends on 31 March 2025, your company accounts deadline is 31 December 2025.
