This is the first in a 3 part series on Residency status in Portugal.
Increasingly, countries challenge former residents who attempt to move to another. Although the rules vary, most states define a “resident" as an individual who is in the state for other than a temporary or transitory purpose. Countries consider a person’s “residence" or home to be the place of his or her permanent home to which he or she intends to return to whenever absent from the state for a period of time.
Most claim the right to tax an individual’s income if they are believed to be a resident. Usually, they also impose tax on 100% of a resident’s income from all sources, including investment portfolio income.
