Most tax reference guides on the internet cover a handful of major economies in depth, or every country shallowly. Global Tax Guide aims for full coverage - every UN member state, plus territories, dependencies, and disputed or partially recognized jurisdictions - with a consistent, concise format: corporate rate, personal rate, and VAT/GST rate on every page, and progressively deeper detail (residency rules, CFC rules, thin capitalization, treaty network) as each jurisdiction is built out.
Global Tax Guide is produced by tk.cpa AI Lab, the same team behind cpavalidated.com, a free US federal and state tax reference library. Where cpavalidated.com focuses on US domestic tax law in depth, Global Tax Guide takes the opposite approach: breadth across every jurisdiction on Earth, positioned as a practitioner-quality quick-reference rather than a substitute for jurisdiction-specific advice.
Every rate on this site is sourced and dated. The majority of jurisdictions are sourced from PwC's Worldwide Tax Summaries, cross-referenced against each jurisdiction's own "last reviewed" date. Where PwC does not cover a jurisdiction, rates are drawn from other named, linked sources - national tax authorities where available, and reputable secondary compilations otherwise - with every source disclosed at the bottom of the page it supports. Pages never assert a rate without a linked source and a "last verified" date, and where a rate could not be independently confirmed this project says so explicitly rather than guessing.
Global Tax Guide is a reference tool, not tax advice. Tax law changes, rates move, and every jurisdiction has exceptions, thresholds, and special regimes that a single summary page cannot fully capture. Always confirm a position with a licensed advisor in the relevant jurisdiction before relying on it - and if you need that advisor, tk.cpa's boutique international tax practice may be able to help; see cpavalidated.com for contact details.
