Buying property in Portugal: a guide for American buyers

The United States taxes its citizens and green card holders on worldwide income regardless of where they live. Among developed countries, the US is one of the few nations that do this. Every other conversation in this article follows from that one fact.

The practical consequence is that a Portuguese tax advantage is only worth something to an American after US tax has been applied on top. Several strategies that make obvious sense for a British, French, or Gulf buyer produce worse outcomes for an American than doing nothing at all. Portuguese advisors, quite reasonably, do not model US tax. American advisors rarely know Portuguese law. The gap between them is where the money is lost.

What Portugal charges you

Portugal places no restrictions on foreign ownership of property. No residency permit is required, no nationality test applies, and Americans buy on the same terms as anyone else. You will need a Portuguese tax number, and non-residents generally appoint a fiscal representative.

On acquisition, IMT transfer tax applies. From September 1, 2026, under Decree-Law No. 97/2026, buyers who are not Portuguese tax residents pay a flat 7.5% on residential property with no exemptions or reductions, subject to a partial refund mechanism if you become tax resident within two years or let the property under moderate-rent conditions. Stamp duty adds 0.8%. Notary, registration, and legal fees follow.

On rental income, non-residents pay a flat 25% on residential lettings, or 28% on non-residential contracts, applied to net income after allowable deductions.

On sale, non-residents have been taxed on 50% of the gain at progressive rates since 2023, the same basis residents use. This was a meaningful improvement over the previous treatment of the full gain.

On dividends and interest from Portuguese sources, the domestic rate is 28%, reduced under the US-Portugal income tax treaty, which has been in force since the 1990s.

All of the above is generally creditable against your US liability through the foreign tax credit. Creditable does not mean cancelled. The credit only offsets US tax on income in the same category, and where the Portuguese rate is lower than the US rate, you pay the difference to the IRS.

The Golden Visa fund problem

The property route to the Golden Visa closed in October 2023 under Law 56/2023. Anyone still marketing Portuguese real estate as a Golden Visa qualifying investment is either misinformed or dishonest. The fund route is now the default path, and for Americans it carries a specific problem.

A Portuguese investment fund is almost certainly a Passive Foreign Investment Company under Internal Revenue Code section 1297. The test is met if 75% or more of gross income is passive, or if at least half of assets produce passive income. Portuguese Golden Visa funds meet this comfortably.

Under the default PFIC treatment, the excess distribution regime, gain on eventual disposal is allocated back across every year you held the investment. Each year’s slice is taxed at the top ordinary income rate that applied in that year, and an interest charge is added for the deferral. On a five to seven year hold, this converts what looks like a capital gain into ordinary income at the highest rate, with interest. The result can materially exceed what a naive calculation would suggest.

Two elections improve this. A Qualified Electing Fund election produces something closer to normal treatment, taxing you annually on your share of the fund’s earnings whether or not cash is distributed. A mark-to-market election is an alternative, but it requires marketable stock and is generally unavailable for closed-end private funds.

The QEF election is the usual answer, and it depends entirely on the fund. To make it, you need a PFIC Annual Information Statement from the fund manager, issued annually and properly certified. Many Portuguese funds are not set up to produce one.

Two questions therefore decide the outcome before any discussion of target returns:

Does the fund support QEF elections for US investors, and will it commit in writing to issuing a PFIC Annual Information Statement every year?

Will the fund and its depositary bank onboard a US person at all? FATCA compliance obligations lead some Portuguese institutions to decline US accounts outright. This is an access problem, not just a tax problem.

Form 8621 must be filed annually for each PFIC position. The QEF election is materially easier to make in the first year than retroactively.

The cultural heritage donation route carries no PFIC exposure, which is a genuine consideration for an American weighing routes rather than an afterthought.

One further mechanical point: non-resident investors are generally required to provide their Portuguese bank with a US tax residency certificate annually. Without it, distributions can face 28% withholding rather than the treaty rate.

Why IFICI is worth less to an American

Portugal’s NHR regime closed to new applicants at the end of 2024. Its replacement, IFICI, offers a flat 20% rate on qualifying Portuguese employment and self-employment income and an exemption on most foreign-source income, for ten consecutive years. Eligibility is narrow: you must not have been Portuguese tax resident in the previous five years, you must hold a qualifying degree at EQF level 6 or above, and you must perform a qualifying high-skilled activity in Portugal, maintained each year. Pension income, which the old NHR covered, is excluded entirely.

American relocation content routinely presents IFICI as the reason to move to Portugal. For a US person, most of its value evaporates.

The foreign-source income exemption is the headline benefit and the one that does least for an American. If Portugal exempts your US dividends, your US rental income, or your US business income, you have not saved anything — the United States taxes that income regardless. All the exemption does is remove a Portuguese tax that you could otherwise have credited against your US liability. For a European relocating from a country that stops taxing them on departure, the exemption is transformative. For an American, it converts a creditable foreign tax into no tax at all, which changes your total bill very little.

The 20% rate on qualifying Portuguese-source income does help, but only up to a point. Where your US marginal rate on that income exceeds 20%, the foreign tax credit leaves you topping up the difference to the IRS. You end up at approximately the US rate either way.

This is not an argument against moving to Portugal. It is an argument against building the decision on a tax benefit that will not materialize. The genuine financial upside of relocation for many Americans lies elsewhere: cost of living, healthcare costs, and, for those leaving high-tax states, the elimination of state income tax — which is covered below and is often worth considerably more than IFICI.

The mortgage currency trap

This is the item that catches the most Americans by surprise, and almost no Portuguese-market content mentions it.

Your functional currency for US tax purposes is the dollar. A euro-denominated mortgage is a liability in a foreign currency, and under Internal Revenue Code section 988, movements in that currency between drawdown and repayment can produce taxable gain.

The mechanism is counterintuitive. If the dollar strengthens against the euro over the life of the loan, the dollar cost of extinguishing your euro debt is less than the dollar value of what you borrowed. The IRS position treats that difference as income. You have received no cash, sold nothing, and made no profit in euro terms, and you may still owe ordinary income tax.

Three features make this worse than it first appears. The gain is ordinary income, not capital gain, so it is taxed at your marginal rate rather than at preferential rates. The section 121 principal residence exclusion does not shelter it. And the treatment is asymmetric: where the currency moves the other way, a loss on a personal residence mortgage is generally not deductible.

The trigger is any disposition of the debt, which includes selling the property, paying the mortgage off, and refinancing. A refinance undertaken purely to secure a better rate can crystallize a tax liability.

The application of section 988 to a purely personal residence, as distinct from a rental or investment property, is a genuinely contested area rather than settled law. That is a reason to obtain specialist advice before borrowing, not a reason to assume it will not apply.

Three practical responses exist. Purchasing and settling up the payment at once avoids the issue entirely. Borrowing in dollars against US assets and transferring the proceeds avoids it. Taking a euro mortgage requires modeling the exposure and tracking the exchange rate at drawdown, which is not something you can reconstruct years later.

Anyone financing in Portugal should also be aware that Banco de Portugal changed its lending framework in August 2026, tightening the maximum debt-service ratio to 45% of net income.

Holding structure: where American advice diverges hardest

European and Gulf buyers frequently acquire Portuguese property through a corporate vehicle — a Portuguese company, or a holding structure in another jurisdiction. There are sound reasons for this in the right circumstances.

For a US person, the same structure can be actively harmful.

Ownership of a foreign corporation brings Form 5471 into your annual filing, with penalties for non-filing that start at $10,000 per form per year. If the company is a controlled foreign corporation, subpart F and GILTI rules can attribute income to you currently, whether or not anything is distributed. Property held in a corporation is generally outside the principal residence exclusion, and the shares may not receive the same treatment on death as directly held property would.

Foreign trusts are worse. Forms 3520 and 3520-A apply, the throwback rules on accumulated income are punitive, and structures that function well under civil law can be treated as grantor trusts producing current US income.

The counterintuitive conclusion is that direct personal ownership is frequently the correct answer for an American, precisely because it is the simplest — the opposite of the default advice a European buyer receives.

This does not mean structure is never appropriate. Madeira’s International Business Centre offers genuinely favorable Portuguese corporate rates and can make sense within a broader commercial position. It means no structure should be adopted on Portuguese advice alone. Any proposal from a Portuguese advisor should be reviewed by a US cross-border specialist before it is implemented, and the review should happen before signing, not after.

Estate planning and succession

US citizens are subject to federal estate tax on their worldwide estate, including Portuguese property.

Portugal is comparatively benign here. There is no inheritance tax. Gratuitous transfers attract stamp duty at 10%, plus 0.8% on real estate, and transfers to a spouse, descendants, and ascendants are exempt.

The complication is that the United States has estate and gift tax treaties with only a limited number of countries, and Portugal is understood not to be among them. Without a treaty, the coordination mechanisms that exist for income tax have no equivalent on the estate side.

Portuguese succession law applies forced heirship — the legítima, a reserved portion that must pass to protected heirs — and it applies by default to Portuguese-situs property regardless of what your will says. The EU Succession Regulation permits an election for the law of your nationality to govern your estate, which allows an American to escape forced heirship. For a US citizen, “the law of your nationality” raises the immediate question of which state’s law, and the election must be made expressly and correctly in a valid will. This is not something to leave to a standard Portuguese notarial will.

Married couples should also confirm how their marital property characterization under their home state’s law interacts with the Portuguese matrimonial property regime recorded at the deed. This affects both Portuguese succession and the US basis step-up at the first death, and it varies by state — the position for each is set out below.

Banking, reporting, and access

Open the Portuguese bank account early. US persons take longer to onboard, and some institutions decline them. You will complete a W-9 and the bank will report your account under FATCA.

Reporting obligations that follow from a Portuguese purchase include the FBAR, FinCEN Form 114, triggered when aggregate foreign account balances exceed $10,000 at any point in the year, and Form 8938 under FATCA at higher thresholds. Both are informational. Both carry substantial penalties for non-filing. Neither creates additional tax.

None of this is a reason to avoid Portugal. It is a reason to have a US cross-border accountant engaged before you transact rather than the following April.

Residency, and the citizenship timeline

For Americans intending to live in Portugal, the D7 visa suits those with stable passive income and the D8 suits remote workers, both of which grant residency without an investment requirement. The Golden Visa routes suit those who want residency without relocating.

One correction worth making, because outdated content on this is widespread. Portugal’s naturalization timeline changed under Organic Law No. 1/2026, in force since May 19, 2026. The qualifying period is now ten years of legal residence, not five. Any article, agency, or advisor still quoting five years is working from a superseded position, and residency plans built on the old timeline need revisiting.

Portugal permits dual nationality and so does the United States. Acquiring Portuguese citizenship does not end US tax obligations. Renouncing US citizenship is a separate decision with its own exit tax consequences and should never be treated as a tax planning step undertaken casually.

Where in Portugal: connectivity from your city

For a second home used several times a year, flight access matters more than almost any property feature. It varies sharply by where you are flying from.

Nonstop to Lisbon is available from New York (JFK and Newark, around 6 hours 45 minutes), Boston (about 6 hours 25 minutes), Philadelphia (about 6 hours 40 minutes), Washington Dulles (about 7 hours 15 minutes), Chicago, Miami (about 8 hours 20 minutes), San Francisco, and Los Angeles (about 11 hours). TAP Air Portugal operates most of these, with United, Delta, and American on selected routes.

Porto has direct US service on a seasonal basis, principally from the New York area, and TAP has been building Porto into a genuine second hub with intercontinental aircraft. Outside the season, a connection through Lisbon or a European hub is required.

Texas and Colorado have no nonstop service to Portugal. Dallas, Houston, Austin, and Denver all require one connection, typically through Newark, Miami, Chicago, or a European hub. Airline route pages listing “Dallas to Lisbon” or “Denver to Lisbon” are showing connecting itineraries, not nonstops.

This has a real consequence for property selection. An East Coast buyer can plausibly use a Lisbon or Cascais apartment for long weekends. A Denver or Dallas buyer is making a connecting journey regardless, which points toward fewer and longer stays, and toward locations where the final leg is straightforward. For a Texas or Colorado buyer, Lisbon and its coastal belt or Porto are easier propositions than the Algarve or Madeira, where a further domestic connection or a long drive is added to an already broken journey.

Routes and frequencies change seasonally and year to year. Confirm current schedules rather than relying on this or any other published list.

What changes depending on your state

Federal tax treatment is identical whether you live in Manhattan or Amarillo. State treatment is not, and for high earners the state question is frequently worth more than every Portuguese tax consideration combined. Two issues matter: whether your state will keep taxing you after you leave, and whether it characterizes marital property in a way that affects how you should take title in Portugal.

California. The most consequential state to leave. California taxes residents on worldwide income at the highest rates in the country, applies a domicile test based on facts and circumstances rather than day counting, and pursues former residents years after departure. Its safe harbor for extended absences is narrower than most people assume. Retaining a home, a driver’s license, voter registration, professional licenses, physicians, or close family ties can all be cited as evidence that domicile never changed. California is also a community property state, which affects how jointly held Portuguese property should be characterized and how basis is treated at the first spouse’s death. For a Californian, the exit is a project in its own right and should be planned and documented before the Portuguese purchase rather than alongside it.

New York. The other aggressive state, and it catches people differently. Alongside the domicile test, New York applies a statutory residence test: spend more than 183 days in the state while maintaining a permanent place of abode there, and you are taxed as a resident regardless of where you consider your home to be. Keeping a Manhattan apartment while living in Lisbon can therefore sustain New York tax exposure on its own. New York City levies a separate resident tax on top. New York is a common law property state, so the community property considerations do not apply.

Texas. The inverse case. No state income tax means there is nothing to exit from on the income side, and the entire analysis reduces to federal and Portuguese treatment. Texas is a community property state, so the title and succession points that apply to Californians apply equally to Texans, even though the tax exit does not.

Colorado. A flat state income tax and materially less aggressive departure enforcement than California or New York, but a documented change of domicile is still required rather than assumed. Colorado is a common law property state.

Florida, Nevada, Washington, and Tennessee. No state income tax, no exit exposure on income, and all common law property states. For residents of these states, the state layer largely drops out of the analysis.

Whatever your state, the marital property characterization should be settled before the Portuguese deed is signed. The deed records a matrimonial property regime, and that regime should be chosen with your US characterization in mind rather than defaulted into at the notary.

How to sequence an American purchase

Engage a US cross-border tax advisor before you engage anyone in Portugal. This inverts the usual order and is the single highest-value step available to you.

Resolve the state residency question first if you are relocating from California or New York, and document it as you go.

Obtain the Portuguese tax number and open the bank account early, allowing extra time for FATCA onboarding.

Decide the financing question with the currency exposure modeled. If you borrow in euro, record the exchange rate at drawdown and keep it.

Decide the holding structure with US counsel, and treat direct personal ownership as the default that a proposed structure must beat rather than the fallback.

If a Golden Visa fund is under consideration, get the QEF commitment in writing before subscribing, not after.

Put a properly drafted will in place electing the governing law for your estate, coordinated between your US and Portuguese advisors.

Portugal is a straightforward place for an American to own property. The difficulty is not Portuguese; it is the interaction between two tax systems that were not designed to speak to one another. Buyers who sort that out first tend to be pleased with the outcome. Buyers who sort it out afterward tend to pay for the privilege.

FAQ

Can Americans buy property in Portugal?
Yes. Portugal places no restrictions on foreign ownership, and no residency permit or visa is required to purchase. Americans need a Portuguese tax number, and non-residents typically appoint a fiscal representative.

Do I still pay US taxes if I buy property in Portugal?
Yes. The United States taxes citizens and green card holders on worldwide income regardless of where they live or where the property sits. Portuguese rental income and capital gains must be reported on your US return, with the foreign tax credit available to offset Portuguese tax paid.

What is the PFIC problem with Portugal’s Golden Visa funds?
Portuguese investment funds almost always qualify as Passive Foreign Investment Companies under US tax law. Under the default treatment, gains are allocated back across the holding period, taxed at top ordinary rates, and carry an interest charge. A Qualified Electing Fund election normalizes this, but requires the fund to issue an annual PFIC Annual Information Statement, which many Portuguese funds do not provide. Confirm this in writing before subscribing.

Is Portugal’s IFICI tax regime worth it for Americans?
Less than for most nationalities. The foreign-source income exemption, which is IFICI’s headline benefit, does little for a US person because the United States taxes that income regardless — the exemption simply removes a Portuguese tax that could have been credited. The 20% rate on qualifying Portuguese income helps only where it exceeds your US rate on the same income. IFICI is also narrowly limited to specific high-skilled activities and excludes pension income entirely.

Can Americans still get a Golden Visa through real estate?
No. The property route closed in October 2023 under Law 56/2023. Qualifying options now include investment funds, capital transfer, business creation, research investment, and cultural heritage donation. The donation route carries no PFIC exposure, which is relevant for US persons.

What is the currency tax trap on a euro mortgage?
Under Internal Revenue Code section 988, a euro-denominated mortgage held by a US taxpayer can produce taxable gain if the dollar strengthens over the life of the loan. The gain is ordinary income, is not sheltered by the principal residence exclusion, and can be triggered by sale, payoff, or refinancing — even though no cash profit has been made. Losses on a personal residence are generally not deductible, making the treatment asymmetric.

Should I buy Portuguese property through a company?
Usually not, if you are a US person. Ownership of a foreign corporation brings Form 5471 filing, potential controlled foreign corporation and GILTI exposure, and loss of certain individual tax treatments. Direct personal ownership is frequently the better answer for Americans, which is the opposite of the advice European buyers commonly receive. Never adopt a structure on Portuguese advice alone.

How long until I can apply for Portuguese citizenship?
Ten years of legal residence, following Organic Law No. 1/2026, in force since May 19, 2026. The previously applicable five-year period no longer applies, and any source quoting five years is out of date.

Are there direct flights from my city to Portugal?
Nonstop service to Lisbon operates from New York, Boston, Philadelphia, Washington Dulles, Chicago, Miami, San Francisco, and Los Angeles. Porto has seasonal direct service, principally from the New York area. Dallas, Houston, Austin, and Denver have no nonstop service and require one connection. Schedules change seasonally, so confirm current routes.

How is rental income from Portuguese property taxed for Americans?
Portugal taxes non-residents at a flat 25% on net residential rental income, or 28% on non-residential contracts. The same income must be reported on your US return, where the foreign tax credit generally offsets the Portuguese tax against US liability on that income.

Does this article constitute tax advice?
No. It presents general information on Portuguese and US tax treatment as of August 2026. Cross-border tax positions depend entirely on individual circumstances and require advice from qualified professionals in both jurisdictions before any transaction.
