Individuals become Portuguese tax residents if they live in the country for 183 days or more per year. Residency change does not happen automatically; one must apply to the local tax authority and provide their registration address in Portugal.
Foreigners must also pay taxes when renting or purchasing property, even if they live in Portugal less than 183 days a year.
Renting or purchasing property in Portugal is one of the conditions for obtaining a residence permit with a D7 visa. The cost and location of the property are not specified. The applicant can choose any villa or apartment they like as long as it has adequate space for all the family members included in the application.
Candidates for the D7 visa prove a passive income of €11,040 per year to obtain residence permits. If relatives are included in the application, the minimum income amount is increased by 50% for a spouse or parent and 30% for each child.
