What Patrician.ch tracks.

For each of the 100 places on the board, Patrician.ch holds the figures a family of real means weighs before a move, each with its source, and every tax figure with the date of its last check.

Patrician.ch is an independent publisher of research. Not tax, legal, or immigration advice.

Income tax on the published 2026 rules. Social contributions, most deductions and treaties are not modeled. Figures are for a non-US single filer. Wealth tax, an exit and your passports are added when you run the engine on your own numbers. Not advice. Residence rules change often. Verify before acting.
