What this value means

RULES, NOT DATES. Each rule carries its own citation, anchor phrase and last_confirmed; the series last_confirmed is the oldest of them. effective_from is null on purpose: the rules rest on different instruments with different commencement dates, and no single date would be true of all of them. The paid response adds due_dates, computed from the rules over a window (default the next 365 days; from/to/year_end/tax query parameters). scripts/deadline-verify.mjs re-fetches every cited source and re-finds every anchor.

The rules

Business days exclude this country's weekly rest days (Saturday, Sunday) and the NATIONAL public holidays in its public-holidays series. Regional holidays are not applied. Each due date is computed from the cited rule; the rule is the citable fact, the date is our arithmetic on it. Thresholds, elections, extensions and sector regimes that move a taxpayer between rules are described in each rule's applies_to and notes, not decided here.
