Can somebody advise what this as I have been getting multiple letter to submit my Corporation Tax *BY* 31/10/25, but your website gives the following:

Please correct the following errors:
The accounting period end date cannot be in the future. Please wait until after 31 October 2025 to file these accounts.

It sounds like you might be being asked to submit a corporation tax return for the year ending 31 October 2024. The due date for that return would be 12 months after i.e. 31 October 2025.

If that is the case you would want to submit CT600 only on TinyTax and edit the dates to be 1/11/2023 to 31/10/2024 and enter your financial accounting data for that year.

If unsure best to ring HMRC to check.
