Support to companies affected by CATO closure and ECCTA changes affecting tax and accounts filing.
We understand how frustrating it is to hear that the joint Company Accounts and Tax Online (CATO) filing service is shutting down on 31st March 2026, and its closure leaves many small businesses unsure of what’s next. As a UK-based company operating in the online tax filing space since 2018, we offer a highly affordable alternative to CATO on our secure, cloud-based platform.
Why is Cato Closing?
The closure of CATO reflects a wider shift to modernise how UK companies report financial data. New rules under the Economic Crime and Corporate Transparency Act (ECCTA) require updated digital standards, enhanced tax reporting, and identity verification. From 1 April 2026, CATO will no longer meet these needs—which is why companies will need modern software solutions like ours to stay compliant.
We understand the importance of simplicity and support for small businesses. That’s why, unlike other providers, our service lets you file your CT600 and iXBRL Accounts to HMRC and Companies House simultaneously — with no platform switching and no extra steps.
Type your company name into Quick Start then select dates, company size, and tick the box for HMRC and Companies House.
Review your automatically generated CT600 return, Companies House accounts, and iXBRL filings. Edit and save whenever you need.
Complete all 3 filing templates by providing your company’s information via our simple guided steps and built-in validation.
Click to chat with us if you have any questions during the filing process and our in-house team of experts will respond straight away.

Can't praise them enough! Their online chat meant that queries were dealt with immediately and to a high standard. The best software I have used and I've been in the profession for nearly 25 years!
~ Dipa Patel
Excellent support from this provided. Only downside is that their software does not cover all areas e.g. tax returns for LLPs or amendments. However what they do, they do well with humans on hand...
