AATAX connects directly to HMRC, tracks every quarterly deadline, and gives your clients a portal they’ll actually use. Built for accounting agencies that want compliance to feel considered, not frantic.
Quarterly periods and submission dates per HMRC’s published MTD schedule.
MTD compliance is not one problem — it’s four. Authorising with HMRC, keeping a client book tidy, never missing a quarter, and handling everything as though a regulator might ask tomorrow. AATAX is four things, each done thoughtfully.
Still something unresolved? The help centre has longer treatments of each topic.
Making Tax Digital for Income Tax is being phased in for sole traders and landlords registered for Self Assessment. It becomes mandatory from 6 April 2026 for qualifying income over £50,000, 6 April 2027 for income over £30,000, and 6 April 2028 for income over £20,000. It requires digital record-keeping and quarterly submissions to HMRC.
AATAX integrates with HMRC APIs through your Agent Services Account. That lets you submit quarterly updates and the final declaration on behalf of your clients, securely and compliantly, with every call traceable in an audit log.
Yes. Your clients get a portal where they can upload documents and see their submission status. You keep full control over what is submitted and when — the portal is for visibility, not unilateral filing.
