The rules move. Be told when they do.

Sent when it earns the send, not on a schedule. Never shared, one tap to stop.

Income tax on the published 2026 rules. Social contributions, most deductions and treaties are not modeled. In Portugal employees also pay social security at 11% of salary, with no cap. 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.
