Will I become a tax resident in Portugal on a D8 visa?

Updated · Taxes guide · Not legal advice

The visa itself doesn't make you a tax resident; Portugal's tax-residency test does. Under the Personal Income Tax Code (CIRS, article 16) you're resident if you spend more than 183 days in Portugal in any 12-month period, or if you have a home there in conditions suggesting you intend to keep it as your habitual residence. Most people living in Portugal on a D8 residence permit meet that test and are taxed on worldwide income.

Americans: two tax systems

US citizens keep filing US returns wherever they live. The US–Portugal tax treaty, the foreign earned income exclusion and foreign tax credits are how double tax is usually avoided; see US treaty and social security.

Incentives

The old NHR regime closed to most newcomers; its successor is the IFICI regime for specific activities. See IFICI.
