Americans moving to Portugal in 2026: what changes for your taxes, bank, car and healthcare

For US citizens moving or retiring to Portugal: the tax treaty says US Social Security paid to a Portuguese resident "may be taxed" in the US, not "only" there, so see a cross-border tax adviser before counting on a number. You keep filing a US return, plus an FBAR above $10,000 in foreign accounts. Portuguese banks report US clients' accounts under FATCA. Your US license stays valid for residents under 60 if issued or renewed within 15 years. Medicare usually does not pay abroad, so residents register with the national health service (SNS).

Other Urbanis guides cover which visa fits you in D7 vs D8 visa, the purchase process in buying property in Portugal as a foreigner, yearly owner taxes in owning a home in Portugal from abroad, and the long-term path in permanent residence and citizenship.

US Social Security and pensions under the tax treaty

The US-Portugal income tax treaty, in effect since January 1, 1996, says in article 20(1):

(a) pensions and other similar remuneration derived and beneficially owned by a resident of a Contracting State in consideration of past employment shall be taxable only in that State; and

(b) social security benefits and other public pensions paid by a Contracting State to a resident of the other Contracting State or a citizen of the United States may be taxed in the first-mentioned State.

Paragraph (b) gives the US the right to tax US Social Security paid to you in Portugal. It says "may be taxed", not "shall be taxable only", so the text does not by itself remove Portugal's right; Portuguese residents pay income tax on their worldwide income. Article 25 sets out how each country gives relief for tax paid to the other. That gap between "may" and "only" is why online guides contradict each other.

Private pensions from past employment fall under paragraph (a): taxable only where you live. But the Protocol's "saving clause" lets the US tax its citizens "as if the Convention had not come into effect", and its exceptions name article 20(1)(b), not 20(1)(a). US government service pensions follow article 21. Whether a 401(k), IRA or annuity fits paragraph (a), the annuity rule in article 20(2) or another article depends on the plan.

This is general information, not tax advice. Before you move, ask a tax adviser who works in both countries to map each income stream to an article and to both returns. Portugal's IFICI regime does not exempt foreign pensions; see IFICI, the regime that replaced NHR.

You keep filing with the IRS

The IRS states: "If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you are in the United States or abroad." You are taxed on worldwide income, and benefits such as the foreign earned income exclusion and the foreign tax credit only apply if you file.

The calendar-year return is due April 15. If on that date you live outside the US and your main place of business is also outside the US, you get an automatic extension to June 15, as long as you attach a statement saying so to your return. Interest still runs on tax not paid by April 15.

On top of the return:

• FBAR (FinCEN Form 114): required when your foreign accounts together exceed $10,000 at any time in the year. It is filed electronically with FinCEN, not with your tax return, and is due April 15 with an automatic extension to October 15.
• Form 8938: attached to your return. If you live abroad with your tax home outside the US, the threshold is more than $200,000 on the last day of the year or more than $300,000 at any time, filing single; $400,000 or $600,000 on a joint return. "Living abroad" means a bona fide resident abroad for the full tax year, or abroad at least 330 days in 12 consecutive months.

On the Portuguese side, you become tax resident if you stay more than 183 days in any 12-month period, or have a home here you intend to keep as your usual residence.

Opening a Portuguese bank account as a US person

You need a Portuguese tax number (NIF) first; gov.pt names opening a bank account among its uses. While you live outside the EU, you request it through a tax representative.

The US-Portugal FATCA agreement was signed on August 6, 2015, and the US Treasury lists it as in force since August 10, 2016. Under article 2, Portugal collects "the name, address, and U.S. TIN" of each US account holder at a reporting Portuguese bank and sends it to the US every year. Expect questions about your US status and taxpayer number. Each bank sets its own onboarding rules, so ask it before you travel. The account then counts toward your FBAR and Form 8938 totals.

Driving in Portugal with a US license

Since August 1, 2022, Decree-Law 46/2022 lets OECD-country licenses be used in Portugal even after you become a resident, if the license is valid, it was issued or last renewed no more than 15 years ago, and you are under 60. IMT names the United States in its list of covered countries.

To exchange it for a Portuguese license, IMT says these holders take no driving tests for the categories exchanged and, for a car license (category B), need only a medical certificate your doctor submits electronically. You apply on the "A Minha Carta de Condução" portal with, among other documents, a certificate of authenticity of your license, then go to an IMT office for biometrics. The fee is €30, 10% less online, and the exchange is completed only with proof of residence in Portugal.

Healthcare: SNS registration and Medicare

Medicare's own page says it "usually doesn't cover health care while you're traveling outside the U.S." and its drug plans do not cover prescriptions bought abroad.

In Portugal, any foreign national with legal residence can get an SNS user number (número de utente), assigned on your first visit to a public health unit. For the SNS to cover costs, your record needs your ID, Portuguese NIF, full Portuguese address and a valid residence permit. You then register at your local health center (centro de saúde). The SNS 24 line is 808 24 24 24; emergencies are 112.

Your first 90 days checklist

1. Get your NIF, through a tax representative if you still live outside the EU.
2. Open a Portuguese bank account and note it for your FBAR.
3. Follow your residence permit with AIMA (see D7 vs D8 visa).
4. Get your SNS user number and register at your health center once you hold the permit.
5. Check your US license: under 60 and issued or renewed within 15 years, or plan the exchange.
6. Count your days in Portugal: more than 183 in 12 months makes you tax resident.
7. Book a cross-border tax adviser before the April 15 and June 15 US deadlines.
8. Set your budget with Porto vs Lisbon cost of living.
