No credit card required · Setup in 2 minutes
Every section of the return, actually built
Most software handles the common cases and leaves the rest to a spreadsheet. Maddiq submits directly to HMRC across every category below.
Personal Tax / Making Tax Digital for Income Tax. Coverage current as of your firm's Maddiq version.
A return your client can
actually complete themselves
One guided step at a time, in plain language, not tax jargon. Built-in guidance flags the things people commonly forget — a trading allowance on side income, Marriage Allowance, a Child Benefit charge — before they submit, not after.
Every figure a client enters writes straight into your firm's records. Review, adjust, or take over at any point — nothing is locked to the client-only flow.
