Methodology & data sources
Transparency is the core of our E-E-A-T: this page documents where every tax figure comes from, what kind of rate it is, the derived numbers we calculate, and the important limits of all of it. GlobalTaxBook covers 96 countries and territories across 8 regions. This snapshot was compiled in June 2026 and reflects roughly the 2025 tax year.
Important: the rates here are statutory headline rates — not effective rates, and this site is general information, not tax advice. Tax law is complex and changes often; your actual liability depends on residency, income level, deductions, treaties and personal circumstances. Always verify with the relevant country's official tax authority and a qualified tax professional before making any decision.
The five figures we publish per country
- Top personal income tax rate. The highest statutory marginal rate on personal income (the rate on the top income band). It is not the rate an average earner pays. Where a country charges no personal income tax on salaries, we show 0%.
- Corporate income tax rate. The main headline (national) corporate income tax rate. Effective rates differ with incentives, surcharges, local/sub-national taxes and the OECD 15% global minimum tax on large multinationals.
- Standard VAT/GST rate. The standard value-added or goods-and-services tax rate. Most countries also apply reduced rates to food, medicine and other essentials, which we do not list. Some countries have no VAT at all.
- Capital gains treatment. A short description of how an individual's capital gains are taxed — a rate, "taxed as income", or an exemption note. Holding periods, asset type and residency frequently change this.
- Employee social security. A brief note on mandatory employee social-security or payroll contributions, where they are a well-established headline figure. Employer contributions, which are often larger, are not the focus here.
Every figure is a published statutory rate captured as a static snapshot in our dataset. We do not invent numbers; where a reliable figure for a field was not available we omit it (shown as "—") rather than guess.
Derived figures we calculate (and why they're rough)
A few numbers on the site are our own transparent calculations over the real rates above:
- Rankings simply sort countries by one published rate (e.g. corporate tax ascending). Countries with no figure for that rate are excluded from that ranking.
- Headline tax level / "band" adds the three comparable headline rates (top personal income + corporate + standard VAT, treating a missing rate as 0) into a single crude signal, then labels it low / moderate / high. This is only a rough indicator of how heavy a tax system looks on paper — it is not an effective tax rate.
- The comparison calculator applies each country's top income-tax rate to your whole income and adds standard VAT on an assumed ~50% of net spending:
headline tax ≈ income × (top income-tax rate) + net income × 50% × (standard VAT rate)
Because it uses the top marginal rate against all income, it overstates income tax for most people. It exists to make headline rates tangible, not to estimate a real tax bill.

Limitations
- Statutory, not effective. Top marginal and standard rates rarely equal what a given person or company actually pays.
- National headline only. Sub-national taxes (US states, Swiss cantons, Canadian provinces) and surcharges are summarised in notes, not fully modelled.
- Rates change. Budgets and reforms move rates every year; a snapshot can lag the present.
- Residency matters. Where you are tax resident, where income arises, and citizenship-based taxation (US) can override headline rates entirely.
