The record

Purpose: Q Tax Agent helps accounting practices agree a client tax plan, keep records reconciled, and monitor actual results against the plan throughout the year.
Audience: The software is for UK accounting firms managing sole-trader clients.
Free features: Bookkeeping, tax calculations and planning are free to use with no monthly subscription.
Inputs: Records can come from read-only Open Banking feeds, PDF or CSV statements, manual entry, and previous submissions.
Categorisation: AI suggests whether transactions are business or personal expenses based on previous categorisation decisions, while the practice reviews and corrects them.
Tax monitoring: The practice portal tracks the client against the agreed plan and monitors CIS through the year.
HMRC filing: Q Tax Agent files quarterly MTD updates and SA100 returns under the practice’s HMRC agent authorisation.
Client portal: Clients can connect a bank, capture receipts, view an estimated tax amount, and answer one-off questions through secure links.
Security: Q Tax Agent says its Open Banking connections are read-only, it does not hold banking credentials, and its primary service-data hosting is in the UK.
Access controls: The company page states that practice access is role-based and uses two-factor authentication.
Regulatory recognition: The site states that Q Tax Agent is HMRC-recognised for Self Assessment and Making Tax Digital for Income Tax.
Support: The company says it provides guided onboarding and stays with practices through their first quarterly cycle.
Usage limit: If two consecutive quarterly updates for a client are unpaid, new bank transactions stop arriving for that client; one payment restarts the feed.
