We're building this tool with the same region-aware approach as the rest of our toolkit. The UK version will run on HMRC's actual rules; the US version will use IRS publications and state-level adjustments where relevant — not a generic average.

Separate logic engines per country — no shared "averaged" math.
Plain-English breakdown of every calculation step.
