Tax, modeled place by place.

Income tax at any income, social contributions where modeled, capital gains, wealth tax, inheritance and gift tax, the special regimes for new arrivals, and the exit rule of 35 home countries. Read from the tax law of each place, checked every day.

What is measured

For each of the 100 places on the board: income tax on 2026 rules at any income, social contributions where they are modeled, capital gains, wealth tax, inheritance and gift tax. Where a place runs a special regime for new arrivals, the regime is modeled as a published rule. The exit rule of 35 home countries is held as well.

Where it comes from

The tax law of each place, read from the official text or the tax authority's own tables. Every tax figure on the site names its official source and the date it was last checked.

How it is checked

AI research agents check every country and territory on the board every day for a change in the rules. The model's income tax is also set beside the tax authority's own calculator or official table, on the checked table on the About page.
