Dear Admin,

Successfully files executed CT600 for 1 April 2023 – 31 March 2024.

Trying to file CT600 for 1 April 2024 – 31 March 2025 but I cannot find an option for a new filing. I click on file account but it keep showing error if I try to upload 1 April 2024 – 31 March 2025 excel accounts. Kindly support.

The quick solution would be to log in and then search for your company again from tinytax.co.uk home page, select accounts, and manually enter the data into the form.

If you could email us your excel then we could take a look at why that does not import too. Just respond to one of the emails we sent you when signing up.

I do not want to do manually data input. I might as well go to HMRC. The excel is in .csv and .xlsl but none of them is working. Thanks.

The CT600 is the submission for corporation tax to HMRC, which has been completed. The accounts is a separate filing to Companies House which has not yet been filed. To file your accounts to Companies House please search for your company on tinytax.co.uk and select "Accounts", complete the form and then "Submit Accounts"
