Yearly tax return

Your first IRS return in Portugal

Every tax resident files an IRS return each spring for the year before. The first one after a move is the hardest, because it mixes Portuguese and foreign income.

The year you arrive

Portugal splits the year you move. You are taxed as a resident from the day you become resident, and as a non-resident before that. In practice:

  • From your arrival date, you declare worldwide income: salary, freelance income, rents, dividends, interest and gains, wherever they come from.
  • Before that date, only Portuguese-source income is taxed in Portugal.
  • Your arrival date should match the date of your tax address change. Keep proof of when you moved.

Which parts of the form you will use

AnnexFor
RostoPersonal details, household and residence
Annex AEmployment income from Portuguese employers
Annex BFreelance income (recibos verdes) in the simplified regime
Annex JIncome from abroad, and foreign tax already paid
Annex LIFICI, if you were accepted

Avoiding double tax

If another country already taxed part of your income, you declare the foreign tax in Annex J. Portugal gives a credit under the tax treaty with that country, so you do not pay twice. Keep the foreign payslips, tax certificates and bank statements.

Regimes that lower the bill

  • IFICI: 20% on qualifying work income if you applied by 15 January. See the IFICI guide.
  • IRS Jovem: up to age 35, part of your work income is exempt for your first ten years of earning: 100% in year one, 75% in years two to four, 50% in years five to seven, and 25% in years eight to ten, up to 55 times the IAS (about €29,500). It cannot be combined with IFICI or the old NHR.
  • Joint filing: married couples and civil partners can choose joint or separate filing each year. The portal shows both results before you submit.
Automatic IRS does not cover foreign income or most freelancers, so a first return after a move is almost always filed by hand. Mistakes here are the main reason we see tax letters in a client's second year.

Frequently asked questions

When do I file my IRS return in Portugal?

Between 1 April and 30 June of the year after the income was earned. Any tax due is paid by 31 August.

Do I have to declare foreign income?

Yes, from the date you become resident. Residents declare worldwide income, and foreign tax already paid is credited under the relevant tax treaty.

Can I use Automatic IRS in my first year?

Usually not. Automatic IRS does not cover foreign income or most freelancers, so a first return after a move is normally filed by hand.
