Source: the Patrician.ch board, an original ranking of 100 residence addresses across 47 countries and territories. Tax rates, thresholds and routes are sourced. Cost, safety, schools, sun and beauty are Patrician.ch editorial indices. Figures current to October 2026. Updated . Cite as: Patrician.ch, Kept: the tax that follows a US passport, 2026, patrician.ch/visuals/kept-us-citizen-abroad-2026/, October 2026.

The United States taxes its citizens on worldwide income wherever they live. The picture puts the same $1,000,000 through 12 financial centers on the board, once for any other passport and once for a US citizen, from the Keep Index 2026.
Where a place taxes less than the US would, the American pays the difference to the US. Dubai takes 0% from anyone else and 32% from a US citizen. Across the board, a US citizen pays more in 28 of the 100 places.
Foreign tax credits and the exclusion for earned income soften the floor at lower incomes, and renouncing has its own rules. The page on how a US citizen is taxed abroad gives them.
