How we use sources

A state's own revenue department outranks its statute for published figures; the statute outranks the department when the department has not yet republished after a law change. Research organisations are used to cross-check and are never the source of record — our build fails if one is recorded as a primary source for any jurisdiction. Full detail in the methodology.

If a link here has rotted or points at the wrong year, let us know.
