Amendment activity

Sections amended in parts administered by Department of Treasury 13 amendments, Oct 2023 – Sep 2026
Oct 2023 Sep 2026

11 further amendments in these titles carry no part identifier and cannot be attributed to a specific scope, so they are excluded from the chart rather than assigned to one.

Attribution is exact, not estimated: each scope is expanded to the set of parts inside it in the current structure, and only amendments to those parts are counted. Dated by issue date, not amendment date — the two differ in about half of all rows.
