Why am I getting the error The period to which this return applies does not coincide with the effective from/ to dates for period ending after 31 March 2024

Some users may be experiencing the error The period to which this return applies does not coincide with the effective from/ to dates on any file that has an accounting period ending after 31 March 2024.

This is due to the 2023 taxonomy not yet been implimented into the corporation tax software. 

We are working to get this implimented as soon as possible. Files with these dates will currently be unable to be filled.
