How it works

Built different from a generic AI tool

1

Grounded in HMRC manuals

Every answer is anchored in actual HMRC internal manuals — Employment Income (EIM), Self Assessment (SAM), Capital Gains (CG), Inheritance Tax (IHTM), Business Income (BIM), VAT, Capital Allowances, National Insurance — plus the underlying tax legislation (ITA 2007, VATA 1994, CTA 2009/10, ITEPA 2003, ITTOIA 2005, and more).

2

Current-year rates baked in

Personal allowance, NI thresholds, VAT registration threshold, CGT annual exempt amount, dividend allowance, pension annual allowance — every answer uses the live 2026-27 figures. We don't guess and we don't quote out-of-date numbers.

Plain English, not jargon

HMRC's manuals are written for tax inspectors, not people. We translate the language into clear answers you can act on. Sources cited so you can verify everything.
