Most expat cases start with residency timing, Modelo 3 and Anexo J reporting, foreign income classification, treaty relief, IFICI or NHR status, social security, and coordination with an accountant in the home country.
Portugal taxes its residents on their worldwide income. Where another country also taxes the same income, the tax treaty between the two countries, if there is one, decides which country may tax it, and Portugal gives a credit for the foreign tax, limited to the Portuguese tax on that income. We advise on the Portuguese side; your adviser abroad covers that country's return.
New arrivals may qualify for IFICI, the tax incentive for scientific research and innovation, if their activity is eligible. NHR is closed to new entrants. Existing NHR holders keep their status for the rest of the original ten-year period and claim the treatment in their annual returns. Which regime applies depends on when you became resident and what you do.
Taxbordr provides Portuguese and cross-border tax advice: written advice, IRS returns, IFICI, foreign income, social security and coordination with accountants abroad. A certified accountant keeps a company's accounts: yours, or our partner accountant.
