What it does
Exact every time
Bracket lookup from a versioned dataset, exact decimal arithmetic, and a locked figure the written answer may only restate.
Every figure is worked out exactly from official rates, never estimated.
Answers with the right year's law
Answers use the law and rates in force for the date in question, so a question about a past year gets that year's rates.
A 2023 question is answered with 2023 law.
Sub-national where the data exists
States, provinces, cantons and territories are modelled where a parameter pack actually carries them — and reported as unmodelled where it does not.
Onboarding a country means publishing assets, not editing code — and a country can only claim what its assets support.
Every figure arrives with its bracket breakdown.
A total on its own is a number to be trusted. A total with the bands, the rates and the amount taxed in each is a number that can be checked — by you, by a reviewer, or by an inspector two years from now.
Every answer records the sources it used, so it can be checked and reproduced later.
- Each band shows the income falling in it, the rate and the tax
- The allowance and its taper are shown, not folded into a total
- Every answer records the rates and sources it used

A calculator that quietly approximates is worse than no calculator. Each engine publishes what it models and what it does not, and the assistant abstains rather than guessing outside that.
