MTD software for sole traders: what do you need?

Last updated: 13 October 2026

In short: For MTD for Income Tax you need software that keeps digital records and can send quarterly updates and a Final Declaration to HMRC through its API. HMRC publishes a list of recognised products. The best choice is one you will actually use every day on the job, not just at year end.

What MTD software must do

  • Store income and expense records digitally
  • Categorise them into HMRC's fixed categories
  • Send quarterly updates to HMRC
  • Submit the annual Final Declaration

Some products do all of this in one place. Others keep the records and pass data to a bridging tool or your accountant.

What to look for as a tradesperson

  • Works from your phone, in the van or on site
  • Creates quotes and invoices, so records build themselves
  • Tracks payments so turnover is accurate
  • Simple enough that you keep it up every week
