The tools
Do I need Making Tax Digital?
Enter your self-employment and property income before expenses, and see whether MTD for Income Tax applies to you and from when.

How these tools work
Every tool here works in your browser. What you type is not sent to FileThat, and there is no account to make.
The rules behind each one come from gov.uk guidance, checked when the tool was built. They give a guide from the figures you enter: HMRC decides from what you actually send.
When you are ready to keep your records and send your updates to HMRC, FileThat does that too.
