Just a heads up – if you’re not already aware - not to file CT600 returns for periods ending after 31st March 2020. HMRC need to update their systems due to the CT rate going back to 19% following the budget instead of the previously announced 17%. They hope to have this done by 2nd week of July. More info on the HMRC CT service availability page. Seeing the budget was 12th March you would think they would have resolved this by now. Thanks to Taxfiler support for great service.
