US tax for Americans in Portugal
There is a US–Portugal income tax treaty and a totalization agreement. The non-habitual resident regime closed to new entrants and was replaced by a narrower incentive aimed at scientific research and innovation — so recent arrivals generally pay more Portuguese tax than earlier ones, which usually means a larger credit and a smaller US bill.
NHR closed, and what replaced it is much narrower
The non-habitual resident regime closed to new entrants. The incentive that replaced it, with effect from 1 January 2024, is aimed at scientific research and innovation: broadly a 20% rate on eligible employment and self-employment income for ten years, limited to people in qualifying activities who have not been Portuguese tax resident in the preceding five years, with registration deadlines that are short and unforgiving.
It is not a general-purpose expat regime, and anyone planning on the strength of what NHR used to offer is planning around a regime that is closed. Confirm which set of rules applies to you before doing anything else — including whether you hold grandfathered NHR status from an earlier arrival.
More Portuguese tax usually means a smaller US bill
This is the reverse of Spain and Italy. Where an arrival falls outside the new incentive and pays ordinary progressive rates to 48%, the Portuguese tax on a professional salary generally exceeds the US tax on the same income — so the credit removes the US liability and leaves a carryforward.
Where the 20% incentive rate applies, Portuguese tax is lower, the credit is smaller, and at higher incomes part of the saving lands on the American return instead.
Pensions are allocated by the treaty, article by article
Portugal is a common retirement destination, and pensions are where the treaty does real work. Which article applies depends on the type of pension: a government pension and a private one are not treated alike, and a lump sum is not treated like a stream of payments.
There is no general rule that produces the answer. It is settled by reading your own facts against the treaty text, which is worth doing before the first drawdown rather than after.
Portuguese funds and PPR products
Portuguese investment funds and PPR retirement products are tax-favoured locally and are frequently PFICs or reportable assets to the United States. The wrapper that makes a Portuguese return simple can make the American one considerably less so, with Form 8621 and Form 8938 both in play.
The totalization agreement covers the social security half
Portuguese social security sits inside the totalization agreement, so a self-employed American contributing there generally escapes the 15.3% US self-employment charge, on a certificate of coverage — independent of whichever income tax regime applies.

Questions Americans in Portugal ask
Can I still get the NHR regime?
No — it closed to new entrants. The incentive that replaced it from 1 January 2024 is narrower: broadly 20% on eligible employment and self-employment income for ten years, for people in qualifying research and innovation activities who were not Portuguese tax resident in the previous five years.
Does Portugal tax my US pension?
The treaty allocates pension taxing rights, and which article applies depends on the type of pension — a government pension and a private one are not treated alike, and a lump sum is not treated like a stream. It is settled by reading your own facts against the treaty, not by a general rule.
I hold NHR status from an earlier arrival. Does it continue?
Grandfathering depends on when you registered and on your own facts, which is exactly the thing to confirm rather than assume. What is certain is that the regime is closed to new entrants.
Are my Portuguese funds or PPR a problem on the US return?
Frequently, yes. They are tax-favoured locally and are often PFICs or reportable assets to the US, which brings Form 8621 and Form 8938 into a return that the Portuguese side made look simple.
I have not filed for several years while in Portugal. What now?
If the failure was non-willful — which describes most people in this position — the Streamlined Foreign Offshore Procedures waive the failure-to-file, failure-to-pay and FBAR penalties: three years of returns, six years of FBARs, and Form 14653.
Moving to Portugal, or already there?
