US citizens and permanent residents
As we know, if you https://www.wealthbadge.com/4-ways-to-live-in-the-usa-and-pay-no-taxes/ are born in the United States, you are automatically a US citizen. That means that you will pay taxes on your worldwide income regardless of where you live, subject to the exemptions that we often discuss here.
However, it is possible to live in the United States part-time (or via one method, possibly even full-time). Otherwise, you could always renounce US citizenship (as many folks are doing) and return as a non-citizen.
Non-US citizens, including former US citizens
Non-US citizens have a leg up on native-born citizens when it comes to tax-free treatment. The United States is not only the world’s largest tax haven, but also a haven for many seeking higher education and other services. That means that there are certain exceptions that allow non-citizens to live full-time in the United States without paying US taxes.
In general, a former US citizen who has given up his or her passport is treated the same as any other non-citizen. The US does not discriminate so long as the Substantial Presence Test is not met and income earned by the non-citizen is not of a US source.
