The only MTD ITSA platform built exclusively for UK tax agents. Manage quarterly submissions for all your clients from one premium command centre.
Give your clients a practice code. They file in their own app. You stay in control of everything.
Your client downloads DoneTax or DoneSE and enters your practice code. From that moment, you are connected. They log their income and expenses throughout the quarter in their own app. You see everything in DoneTax+ and submit directly to HMRC when they are ready. No chasing. No manual data entry. No confusion about MTD.
Every review, approval, and submission is logged. Know exactly what happened, when, and who acted. Nothing is ever lost.
No endless onboarding. Just enter your client's National Insurance Number and you're connected.
OAuth 2.0 authenticated. Bank-grade encryption. Instant confirmation. Never leave the platform.
Authenticate your HMRC Agent Services Account via secure OAuth 2.0. One-time setup. Takes 60 seconds.
