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.

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. The served holiday calendar covers 2026-01-01 to 2026-12-31. Dates outside it are weekend-checked only and may still fall on a public holiday.
Not covered here
We hold no verified rule for these taxes in TR. Each reason is given; where a deadline exists but its source could not be verified, we hold none rather than guess.
- VAT / GST: KDV Kanunu md. 41 on mevzuat.gov.tr still says the 24th of the following month, but GİB circular VUK-149/2022-12 extended VAT filing and payment to the 28th. The only GİB copies found (cdn.gib.gov.tr PDFs) have no text layer the anchor checker can read, and gib.gov.tr itself renders client-side. Seeding the statutory 24th would give the wrong date, so no rule.
