Do I need MTD under £50,000?

Not yet, but you will soon. If your qualifying income is between £30,000 and £50,000, MTD becomes mandatory from April 2027. If it's between £20,000 and £30,000, you'll need to comply from April 2028. Income below £20,000 is not currently in scope, though HMRC may lower the threshold further. Even if you're not required yet, setting up digital records now with August means you're ready when your phase arrives, with no last-minute scramble.
