Professional verification

The Sri Lanka calculator has not yet been reviewed by an independent tax professional. Until it is, results rely on the official sources, worked examples and automated checks below. How our verification works.

Worked examples, recalculated live

Each example was worked by hand from the official rules before publication. The live calculator must reproduce it exactly, to the cent, or the rule set cannot be published.
