Making Tax Digital and CIS: what subcontractors must do from 2026
Making Tax Digital for Income Tax (MTD ITSA) became live for sole traders earning over £50,000 from 6 April 2026.

This guide explains who is in scope now, who joins in April 2027, what quarterly updates require, and how to keep your CIS records in a way that feeds straight into MTD-compatible software.
