Filing the Company’s Annual Financial Statements

At the end of the company’s financial year, the company must prepare the annual statutory accounts. The accounts are filed at Companies House while the accounts and corporation tax return are also filed electronically at HMRC.

When it comes to deadlines, you will file:

  • First accounts with Companies House 21 months after the company’s incorporation date
  • Annual accounts with Companies House nine months after your company’s financial year ends
  • The company’s Corporation Tax Return 12 months after your accounting period for corporation tax ends.

Corporation tax

Your company must pay corporation tax on any taxable profits. The deadline for this will depend on your company’s year-end and is due nine months plus one day after the company’s year-end

VAT return

If you are VAT-registered, you will be required to file a VAT return usually every three months. This deadline is usually one calendar month and seven days after the end of the VAT period, and you have to allow time for the payment to reach HMRC’s account.  Some businesses also opt to use the annual VAT scheme.
