    The Tax AI problem

    Generic copilots fail tax.

    Tax is the highest-stakes domain in legal AI. One wrong rate, one missed treaty, one halucinated authority — and the engagement is over. Here's where standard tools collapse.

    Hallucinated WHT rates

    Generic AI invents withholding tax rates that don't exist. One bad treaty interpretation can cost millions.

    Treaty maze

    3,000+ bilateral DTTs, MLI overlays, BEPS Pillar II. No human reads them all in time for an M&A signing.

    Audit exposure

    Tax authorities now demand source-grounded reasoning. Black-box AI outputs fail KAS / IRS / HMRC scrutiny.

    Verifiable corpus

    Every answer cites primary law.

    Tax Scout grounds every output in the raw text of the controlling treaty, regulation or authority manual. No paraphrase, no “based on general knowledge” — just citation to source.

    The DTT-First Protocol

    Deterministic, not generative.

    Tax Scout follows a fixed 4-step lookup hierarchy. No probabilistic guessing. If the treaty doesn't say it, the engine doesn't claim it.

    Fact intake

    Counterparties, residency, payment type, treaty basis.

    02

    DTT-first lookup

    Bilateral treaty controls before domestic law.

    03

    MLI / BEPS overlay

    Anti-avoidance modifiers automatically applied.

    04

    Source-cited output

    Every rate, every rule grounded in primary law.
