On 6 March HMRC and Companies House announced that their online filing services for corporation tax (CT) returns and accounts will be withdrawn with effect midnight on 31 March 2026. This will be a blow mainly for micro and small companies which are the chief users of the services. If you already use software to submit CT  returns to HMRC and accounts to Companies House the withdrawal of the services won’t affect you. 

Companies that are affected by the withdrawal of services will be allowed to submit accounts to CH on paper but will need to purchase software to file their CT returns. Both the government authorities have help pages on their websites to help companies find suitable software – you can view the GOV.UK version here.

After 31 March 2026 companies will only be able to view accounts and tax returns previously submitted using the free filing services if they take the following steps:

1.    Go to the ‘track your submissions’ page and select the period you want to save a copy of your return for.

2.    Select either the ‘HMRC’ or ‘Companies House’ submission link .

3.    On the filing summary page, select ‘save your return in HTML’.

4.    When prompted select where you want to save the file.
