Last updated: 7 October 2026. Source review completed: 7 October 2026 for the materials listed below.

We use official government and tax-authority pages for material country-specific invoice and tax references. Links below lead to the specific source materials checked, not to tracking redirects. A source note explains its scope and any limitation recorded during review.

How to read the country source blocks

Country pages show a compact Sources & Review block with its Last Reviewed date, linked references and review scope. That date refers to the stated source check; it does not mean an individual invoice was validated or every future amendment was anticipated. Where a source itself has an older update date or an amendment note, that limitation is shown.

Rates and calculations

The VAT, GST and sales-tax calculators perform arithmetic using rates supplied by the user. Their initial zero value is a calculation input, not a suggested or verified rate. The central tax-preset registry records country, tax label, rate, effective date, last-reviewed date and source URL; numeric rates and effective dates are currently null. The tools do not look up state, provincial or local rates, decide registration or tax treatment, or guarantee a compliant invoice.
