How the comparison is calculated

Your income is placed on each country’s own tax scale (converted to local currency with an indicative FX snapshot dated 2026-08-20), run through its full progressive brackets or flat rate, and reported as an effective rate — total income tax divided by gross income. Countries are ranked lowest effective tax first.

This is income tax only. It deliberately excludes social security/national insurance, deductions and reliefs beyond a country’s statutory scale, capital and wealth taxes, and sub-national taxes — US states, Spanish autonomous communities and Scotland all add their own on top. Where a country has a flat expat or small-business regime a mover would genuinely use (Spain’s Beckham, Georgia’s 1% small-business, Thailand’s LTR), you can toggle it; the default is the standard resident scale.

Every rate is a verified fact with a source and date. FX rates are an indicative snapshot, not a live feed, so cross-currency figures are approximate. It is a starting point for comparison, not a filing.

Frequently asked questions

Why is the effective rate lower than a country's headline tax rate?

The headline rate is the top marginal rate — it only applies to income above the highest threshold. Your effective rate is the total tax divided by your whole income, so it is almost always lower. This tool runs your income through each country's full progressive scale to get the real effective figure.

Does this include social security or show take-home pay?

No — it is income tax only. Social security contributions, deductions and reliefs beyond a country's statutory scale, and sub-national taxes (US states, Spanish regions, Scotland) are excluded. Real take-home is lower; treat this as an income-tax comparison, not a payslip.

How does it handle special regimes like Spain's Beckham Law or Georgia's 1%?

Where a country offers a flat expat or small-business regime a mover would actually use — Spain's Beckham (24%), Georgia's small-business (1% turnover), Thailand's LTR highly-skilled track (17%) — you can toggle it per country. Comparing standard rates alone would misrepresent those countries, which is exactly the mistake most comparisons make.

Why isn't Portugal shown?

Portugal is included only once its full progressive bracket table is verified in our database. Showing a headline top rate as if it were an effective rate would be dishonest, so we leave a country out rather than guess.

How current and accurate are the numbers?

Every rate comes from the facts table, each with a source and verification date (see the country guides). Cross-currency amounts use an indicative FX snapshot dated 2026-08-20, so figures move with exchange rates. This is educational, not tax advice.

When to talk to an advisor

Effective-rate comparisons are for orientation. Before you move for tax, a qualified advisor should model your actual position — social security, the regime you qualify for, treaty relief and sub-national rates all move the real number. This tool shows the shape of the decision, not the answer.
