Portugal Tax Residence and Foreign Income

Presence or a habitual home

Residence can arise after more than 183 days in a relevant 12-month period beginning or ending in the income year. A shorter stay can qualify where an available dwelling indicates an intention to maintain and occupy it as a habitual home.

Overnight presence and part-year rules

A counted day includes an overnight stay. Arrival and departure can create part-year residence, but statutory exceptions can extend it; residence is assessed separately for each household member.

Resident income scope

The ordinary rule taxes residents on income from Portugal and abroad. Article 15 applies the resident and non-resident scopes separately in qualifying part-year cases; special relief is not established by this baseline.

Non-resident income scope

For non-residents, IRS applies to Portuguese-source income. Leaving Portugal therefore does not automatically end every Portuguese income-tax obligation.

A nationality-linked departure exception

Portuguese nationals moving tax residence to a jurisdiction on the official favourable-tax list can remain resident for the departure year and four following years, unless an accepted justification is proved. The rule stops when residence moves outside that list.
