# Portugal Tax Residence and Foreign Income

Portugal's ordinary IRS rules distinguish residence, Portuguese-source income and foreign income, with important departure exceptions.

Scope: Selected individual IRS rules under Articles 15 and 16; not an eligibility assessment for NHR, IFICI, treaty relief or a personal tax calculation.

Jurisdiction: Portugal: individual income tax (IRS). Sources reviewed 2026-09-17; review due 2026-12-16.

General information, not personal tax advice. Nationality, tax residence and source of income are different questions. Consult the tax authority or a qualified adviser for your circumstances.

## 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.

Evidence: conditional. [Autoridade Tributária e Aduaneira: Código do IRS: Article 16, residence](https://info.portaldasfinancas.gov.pt/pt/informacao_fiscal/codigos_tributarios/cirs_rep/Pages/irs16.aspx). Source location: Article 16(6)–(7).
