CT Filing Dates

TaxCalc Tax Return Production can be used to file Corporation Tax (CT) returns for accounts periods ending up to a given date. This date is dependent on the version of the software installed. The most recent version is limited by the ability of the HMRC online filing service to correctly process CT returns.

The table below shows the return period end date up to which TaxCalc Tax Return Production can file CT returns depending on the software version installed.

Note that whilst the rates in the software are correct, you may not be able to file online if HMRC have not updated the rates on their system.

The table will not include the most recent dates until this has been done.
