Your US worldwide-income filing and your Portuguese resident position, set out together so nothing falls between the two.
US-Portugal Tax
US-Portugal tax for Americans: one position across two systems.
Yes, Americans living in Portugal deal with US and Portuguese tax at the same time: US citizens and green-card holders keep filing US returns on worldwide income, Portuguese tax residents file in Portugal too, and the foreign tax credit, the 1994 US-Portugal treaty and the $10,000 FBAR rule decide what is reported and owed. US-Portugal tax planning is the work of lining up both returns so each item of income is reported correctly in each country and relief is claimed once.
Movingto is a Portugal-first immigration firm that puts a named, Bar-registered lawyer from its in-house legal team on your case and publishes its fees.

What you get
What you get across both tax systems.
Cross-border tax goes wrong when the two systems are handled in isolation. Movingto's in-house tax counsel builds one picture, advises on the Portuguese and cross-border decisions, and briefs your US CPA.
Exclusion vs credit questions
The foreign-earned-income exclusion versus the foreign tax credit, framed for your facts, including how NHR or IFICI low Portuguese tax can leave US tax due.
Reporting inventory
An FBAR and FATCA account inventory and the PFIC exposure on any Portuguese or EU funds, so the reporting is not missed.
Brief for your US CPA
A written brief for your US CPA, who files your US return, PFIC/Form 8621 and FBAR.
You file in both countries
US citizens and green-card holders file US federal returns on worldwide income regardless of residence, and Portuguese residents file in Portugal too. The two have to be planned together, not run separately.
Credit usually beats exclusion
For most Portugal residents taxed at normal rates, the foreign tax credit offsets US tax better than the exclusion. Under NHR or IFICI, low Portuguese tax means little credit, so US tax can still be due.
FBAR and FATCA are the trap
US persons must report foreign accounts: an FBAR when accounts exceed $10,000 in aggregate, and FATCA Form 8938 above separate, higher thresholds for those living abroad. Missing them is costly.
Watch out for EU funds (PFIC)
Portuguese and EU mutual funds and ETFs are typically PFICs, which trigger punitive US treatment and extra forms. Americans should usually check investments before buying them.
Who this fits
Why use Movingto for US-Portugal tax?
The valuable work is making the two systems talk to each other: the dual-filing position, the exclusion-versus-credit decision, the reporting inventory, and the PFIC and self-employment traps. Movingto's in-house tax counsel advises on the Portuguese and cross-border side and briefs your US CPA.
Good fit for

Choose the relief
FEIE vs Foreign Tax Credit for Americans in Portugal
| Aspect | Foreign Earned Income Exclusion (Form 2555) | Foreign Tax Credit (Form 1116) |
|---|---|---|
| What it does | Excludes earned income up to an annual cap ($132,900 for 2026) | Credits Portuguese income tax paid against US tax |
| Income covered | Earned income only (wages, self-employment) | Most income types with foreign tax paid |
| Best when | Low or no foreign tax on earned income | Portugal taxes at normal progressive rates |
| NHR / IFICI angle | May leave investment and pension income exposed | Low Portuguese tax means little credit, so US tax may still be due |

Common questions
Questions before you engage.
Do I still file US taxes if I live in Portugal?
Yes. US citizens and green-card holders file US federal returns on worldwide income regardless of where they live, so Portuguese residence does not remove the US obligation. Those abroad get an automatic extension to 15 June, though any tax owed is still due in April.
Does the US-Portugal tax treaty stop double taxation?
It relieves it rather than removing US filing. The treaty (signed in 1994, generally effective from 1996) allocates taxing rights and provides relief, but a saving clause lets the US keep taxing its own citizens. In practice the treaty mainly prevents double taxation on the Portuguese side, with the US foreign tax credit doing much of the work for US citizens.
Should I use the FEIE or the Foreign Tax Credit?
It depends on your facts. Movingto's in-house tax counsel sets out the cross-border position and your US CPA makes the election on your US return. For Portugal residents taxed at normal progressive rates, the foreign tax credit usually offsets US tax better and can build carry-forward credits. Under NHR or IFICI, low Portuguese tax means little credit, so the exclusion or residual US tax matters more. The exclusion also covers earned income only.
What are FBAR and FATCA reporting?
FBAR (FinCEN Form 114) is required when your foreign financial accounts exceed $10,000 in aggregate at any time in the year. FATCA Form 8938 is filed with your return above separate, higher thresholds, which are larger for taxpayers living abroad. Many Americans in Portugal must file both.
Are my Portuguese or EU funds a tax problem?
Often, yes. Non-US mutual funds and ETFs, including Portuguese and EU ones, are typically PFICs for US tax, which triggers punitive default treatment and Form 8621. US persons usually check investments, often favouring US-domiciled funds, before buying (IRS Form 8621 page, checked 16 October 2026).
Does NHR or IFICI lower my US taxes?
No. NHR and IFICI lower Portuguese tax, not US tax. Because they reduce the Portuguese tax you pay, they can also reduce your US foreign tax credit, which can leave US tax due. The two sides need to be planned together.
Who handles US and Portuguese tax filings?
Movingto's in-house tax counsel advises on Portuguese and cross-border tax; your US CPA files PFIC/Form 8621 and FBAR, and we brief them. Your Portuguese annual return is covered by the Portugal tax-return filing service.
