income_tax_by_place

Income tax on one yearly income in Patrician.ch's 100 places to live, lowest first, with the effective rate and the patrician.ch page. Covers zero income tax countries, Swiss cantons, US states such as Florida, New York and California, and European capitals. A US state or town that is not one of the 100 (Texas, California, Los Angeles, Houston, Boerne, Tampa, Nashville) is answered through the board place that carries the same income tax, and the result says which. Optionally only named places, a US citizen (taxed by the US wherever they live), or married filing jointly. Use it for "how much tax would I pay in X", "which country taxes $1M least" and "countries with no income tax".
