An American moving to Portugal: taxes on both sides, explained

Zero Tax · Updated July 2026 · 9 min read

A software consultant from Austin moved to Lisbon expecting European taxes to crush her. Two years in, her effective rate is lower than it was in Texas once state-free living, the FEIE and Portugal's IFICI regime are netted out. Her neighbor, another American, moved the same month, bought European index funds with his savings, and created a PFIC reporting nightmare that cost him five figures in accounting fees. Same city, same passport, opposite outcomes. The difference was sequencing.

The rule that changes everything: the IRS moves with you

The United States taxes its citizens on worldwide income no matter where they live. Moving to Portugal does not end your US filing obligations: Form 1040 every year, FBAR if your foreign accounts exceed $10,000 in aggregate, and potentially Form 8938, 5471 or 8621 depending on what you own. Every planning decision has to work in two systems at once.

Three tools coordinate the two systems:

The Portuguese side: IFICI, the regime that replaced NHR

The old NHR closed to new applicants in 2024. Its successor, IFICI (widely called NHR 2.0), is narrower but still powerful for the right profile:

FeatureIFICI treatment
Portuguese employment / self-employment in qualifying activities20% flat rate (vs progressive rates up to 48%)
Foreign dividends, interest, capital gains, rents, royaltiesGenerally exempt in Portugal (non-blacklisted jurisdictions)
Pensions (US or other)Taxed at standard progressive rates; the old NHR pension deal is gone
DurationUp to 10 consecutive years
Who qualifiesNew residents (not Portuguese-resident in the prior 5 years) working in eligible high-value activities: tech, science, education, certified startups and similar categories

If you do not qualify for IFICI, standard Portuguese rules apply: progressive rates up to 48% plus solidarity surcharges, with a 28% flat option on most investment income. Portugal still has no wealth tax on financial assets, and no inheritance tax between spouses and direct descendants.

The two-system logic in one line: Portugal's IFICI exemption on foreign income mostly neutralizes Portuguese tax, and the US then taxes that income anyway. So for an American, IFICI's real value is avoiding double taxation and sheltering Portuguese-source professional income at 20%, not reaching 0%. Anyone selling you "0% in Portugal" as a US citizen is skipping the savings clause.

The right sequence for an American moving to Lisbon

  1. Before the move: break state residency cleanly (domicile, driver's license, voter registration), review your portfolio for future PFIC exposure, and time the move against the FEIE physical presence test.
  2. Arrival year: secure the visa (D7, D8 digital nomad or other route), register as tax resident, and apply for IFICI within the deadline for new residents.
  3. Ongoing: file both returns in coordination (the Portuguese and US filing calendars differ), track days, and keep foreign accounts FBAR-documented.
  4. Exit or citizenship horizon: after 5 years you may qualify for Portuguese citizenship; some Americans then weigh renouncing US citizenship, a separate analysis with its own exit tax rules.

Frequently asked questions

Do Americans in Portugal pay tax in both countries?

They file in both. The FEIE ($132,900 for 2026), foreign tax credits and the treaty mean most income is taxed once, at the higher of the two rates.

Does IFICI work for Americans?

Yes: 20% on qualifying Portuguese professional income and Portuguese exemption on most foreign income. The IRS still taxes worldwide income, so the benefit is coordination, not 0%.

What is the FEIE amount for 2026?

$132,900 per person, plus a housing amount limitation of $39,870. Earned income only.

What is the biggest mistake Americans make in Portugal?

Buying European funds and creating PFIC problems. Keep investments US-domiciled unless advised otherwise.
