HMRC's older free joint filing service for Company Tax Returns has closed, so every UK company now needs HMRC-recognised commercial software to file a CT600. This is a live, dated requirement, not a future one, which is why it's our first product.
What our Corporation Tax product does
It covers the CT600 return itself, the iXBRL-formatted statutory accounts and tax computations that go with it, and HMRC validation and acknowledgement handling, so you get a clear pass or fail before anything is actually submitted. It's built to later fold into CompanySimple, our broader Companies House product, rather than stay a permanently separate tool.
Status
In active development. See our full explainer on what CT600 covers and the real filing deadlines if you want the detailed breakdown, including the difference between the payment deadline and the return deadline.
