Defence‑ready Self Assessment · before you file.
Taxat is the AI‑driven audit defence layer for UK accountants. Reconcile client‑authorised data across ledgers, bank feeds, receipts, and (when authorised) HMRC APIs · then link every return figure to evidence with a living Defence Graph.
Not affiliated with HMRC. Taxat does not access HMRC internal systems or replicate investigation decisioning. It uses official APIs only where authorised.
HMRC scrutiny is rising.
Defensive work is eating your week.
Accountants are forced into manual cross‑checks because enquiry risk feels like a black box. The result is time pressure, stress, and fragile evidence when a figure is questioned months later.
Defensive reconciliation, spreadsheet checks, and document chasing · repeated client‑by‑client.
Even when you’re diligent, you can’t see what data mismatches might look suspicious across sources.
Ledger, bank feed, receipts, and emails live in different systems · so “prove it” becomes a scramble.
Taxat turns defensive work into a governed system · so enquiry readiness becomes a repeatable sign‑off, not a late‑night checklist.
Manual defensive checks scale linearly with clients · and peak season amplifies everything. Taxat aims to reduce the cognitive load by turning evidence and reconciliation into an automated graph.
Stop guessing.
Build an evidence‑backed return.
Taxat operationalises a defence‑first workflow: it reconciles client‑authorised data across sources, flags mismatches early, and links each return figure to its supporting evidence.
Independent “risk visibility” that surfaces cross‑source discrepancies and missing evidence · before you file.
A living evidence map: every figure is traceable to transactions, receipts, and rules · ready for enquiry.
Quantify readiness (0-100), then generate a prioritised action list so teams fix the biggest gaps first.
Hover nodes to see how a single return box links to evidence groups (transactions, documents, rules). Confirmed links render as solid paths; suggested links render as dashed.
Confirmed links render as solid. AI‑suggested links render as dashed with explicit labelling.
A defence workflow your team can repeat.
Taxat is designed to sit above your practice stack. It turns evidence and reconciliation into a system that scales with clients · without adding headcount.

- Ledger exports/APIs (Xero, QBO, Sage)
- Bank feeds via Open Banking
- Receipts + invoices (capture tools or uploads)
- Optional HMRC endpoints where authorised
A control room for enquiry readiness.
See mismatches early, trace figures to evidence, and standardise sign‑off across the team. Taxat is designed for explainability and governance · so your outputs are defensible, not “black box”.
Watch a 60‑sec walkthrough of the core screens and workflow. Tap play when you’re ready.

Every run can generate a manifest (data completeness, rules version, and explainable paths). This is how the same figure can be defended months later · without relying on memory.
Built for regulated data and firm due diligence.
Taxat is designed for explainability and governance. The outputs are evidence‑linked and reproducible · so your firm can defend filings without over‑claiming how HMRC works.
Security materials are available on request (policy outline, data flows, and controls).
Closed beta for select firms.
We’re onboarding a limited number of UK practices to validate workflow fit, calibrate risk rules, and ship the best possible “defence-first” UX before broad release.
Early adopters typically receive onboarding support and preferential pricing once the beta closes (exact terms depend on cohort and integrations).
Note: Taxat is independent and not affiliated with HMRC. It uses authorised HMRC APIs only where permitted by the user.
Answers to the real objections.
Taxat touches sensitive workflows. We keep expectations clear on HMRC affiliation, explainability, and how it fits alongside your existing tools.
