'The period to which this Return's Computation applies does not coincide with the effective from/to dates of the referenced Computation Taxonomy ' error message

The period to which this Return's Computation applies does not coincide with the effective from/to dates of the referenced Computation Taxonomy error message can come up when submitting accounts to HMRC.

This can be resolved by re-generating the accounts IXBRL using the latest taxonomy (accessed via drop-down menu shown below) and making sure you are on the latest ePack for both the accounts and corporation tax.

Please see the following article on how to check your ePack levels here.
