How the calculator works and is tested

Every rate, threshold and date on this page comes from 21 dated records covering 2021 to 2027. Each record names the page it was read from and the day it was retrieved. The calculator applies the record in force on the day of each sale and stops with an error when none is, instead of estimating.

Sales are matched to purchases by the country's own rule: first in, first out by default, the UK's same-day, 30-day and Section 104 rules, and Canada's average cost. A sale not fully valued in the country's currency is flagged and left out of the result, never guessed.

Every country has a calculation engine with its own test file of worked cases. Where a calculator ships sample exports, tests run them through the import adapters and check that each file is detected and read correctly. Type checks, linting, unit tests and backend tests run on every change, and English page renders are compared with stored snapshots.
