Americans move to these five countries by the tens of thousands, and our founder wouldn't base his own family in any of them. That isn't a contradiction: every country on this list is somebody's right answer, and each one continues to fit a specific profile well. But the case against each has grown sharply in the last two years, and most of the coverage aimed at American movers skips it entirely. Here are the downsides of five of the most popular expat destinations in 2026, and who each one is truly for.
Or watch the full breakdown here:
5. Mexico: the biometric state arrives
More American citizens live in Mexico than in any other country on Earth, around 1.6 million, most of them dual citizens. But as of this month, every phone line in the country must be tied to a biometric identity or the line goes dead: roughly 127 million numbers across prepaid, postpaid, physical SIMs, and eSIMs, with no carve-out for foreign residents.
The mechanism is the CURP Biométrica, the biometric upgrade to Mexico's decades-old national population registry code, adding a photograph, electronic signature, fingerprints, and biometric records to a central government database. It is becoming the credential for banking, healthcare, and government business, and your phone number is now downstream of it. The phone mandate is the visible edge of a larger buildout: a 2025 fast-tracked package amended the telecommunications and intelligence laws and created a central intelligence platform with live access to banks, hospitals, and property registries, while private contractors have built 188+ command centers across 26 states wiring together camera grids, license plate readers, and drone feeds. In Chihuahua, an AI-driven system called Plataforma Centinela merges thousands of public cameras with helicopters and drones. Civil groups call it an uncontrolled system of mass social control, in a country that already deployed Pegasus spyware against its own journalists. If your reason for leaving the US is privacy and a smaller state, Mexico is moving the other way. We don't underwrite a jurisdiction on where it is today; we underwrite it on where it's heading.
Who Mexico fits anyway: the economic solvency route grants temporary residency on about $4,400 a month of income or roughly $73,000 in savings, converting to permanent residency in four years, and marriage to a Mexican citizen or a child born in Mexico opens naturalization at 2 years. As a residency flag or a citizenship play for your children, Mexico is among the easiest anywhere.
4. Canada: 50%+ rates and a tax on leaving
Top combined marginal rates in Canada pass 50%, up to 55% in some provinces. Most of the country delivers 4 to 6 months of winter. And relative to its size, Canadians may be the nationality you meet most outside their own borders, leaving in droves for jurisdictions like Panama and Paraguay that want their capital. When the locals with options are heading for the exits, that's not the direction to swim.
The detail most people underestimate: Canada doesn't let you leave cheaply. A departure tax treats your worldwide portfolio as sold at market value on the day you cease tax residency and bills you on the unrealized gains (with different treatment for Americans whose tax residency spans both countries). High rates while you're in, a toll when you leave, and six months of winter in between. The usual draw is cultural similarity for Americans exhausted by US politics; the math argues for thinking hardest of all before choosing it.
3. Brazil: new dividend taxes and the Pix reporting rails
Brazil has overhauled its tax code in the last few years: nearly 30 years of tax-free dividends ended, with distributions above $10,000 a month from one company to one person now facing 10% withholding, dividends sent abroad taxed at 10% regardless of amount, and a new 10% personal income tax on total income above $250,000. With an estimated 433,000 millionaires, the largest concentration of private wealth in Latin America, this was a direct hit on them.
The bigger shift is the reporting layer underneath. Almost every payment in Brazil now moves through Pix, the government-built instant payment system, and since 2025, banks, fintechs, and payment platforms report transactions to the tax authority. A cash economy gives you positive friction in both directions, a kind of soft freedom; Brazil removed the friction and the reporting rails came with it. Spend 183 days there and you're a tax resident inside probably the most sophisticated tax surveillance net in the Americas.
Who Brazil fits anyway: entry is among the most accessible anywhere. The VIPER investor visa takes about $200,000 in property (roughly 30% less in the North and Northeast), the retirement visa about $2,500 a month in pension income, and the digital nomad visa about $2,000 a month. And any child born on Brazilian soil is Brazilian at birth, with permanent residency for the parents and naturalization open after just one year of residency: one of the most generous family provisions in the world.
2. The United Kingdom: nothing left to offer
In 2025, Britain ended its non-dom regime, a tax feature more than 200 years old that made London the default city for global wealth, and replaced it with four years of relief before worldwide taxation. The Tier 1 investor visa closed in 2022 and never reopened, so there is no investment residency route into the UK today. No tax advantage, no investor visa, and the gray weather included at no charge.
The money noticed. The UK is projected to have lost about 16,500 millionaires in 2025 after nearly 11,000 the year before, with something like $92 billion in investable assets attached, leaving Britain with its fewest millionaire residents since the Great Recession. In the same stretch, net migration peaked above 900,000 in a single year, overwhelmingly economic migrants rather than investors. Add a seventh prime minister in a decade, and this is not a base to plan a 20-year structure around. It is the only country on this list with no remaining incentive to offer.
1. Spain: world-class living, worst-in-Europe structuring
The surprise entry. Spain ranks fourth in the world in our Expat Almanac, and on food, climate, healthcare, and the day-to-day experience of being alive it has almost no rival. It is also, for an American, one of the worst places in Europe to structure your affairs. Both things are correct at the same time.
Spain ended its golden visa in 2025, and the legislature has floated a 100% tax on property purchases by non-EU buyers. Whether or not that ever becomes law, a country proposing to double the price of your house purchase is telling you how it feels about your capital. The remaining routes in, the non-lucrative visa and the digital nomad visa, both expect more than 183 days a year of presence, and crossing that line (or creating substantial ties short of it) makes you a Spanish tax resident on worldwide income. The only routes into Spain are now the routes that make you a Spanish taxpayer.
What that means in numbers: marginal income rates past 50% in regions including Barcelona and Valencia; regional wealth taxes on assets you may have already paid tax on; a national solidarity tax of up to 3.5% on net worth above €3 million (Madrid and Andalucía credit the wealth tax in full); and Modelo 720, the declaration of everything you own outside Spain, with a penalty regime so aggressive the European Court of Justice struck part of it down. Behind it all stands Hacienda, one of the most aggressive tax authorities on Earth.
Who Spain fits anyway: the Beckham Law taxes Spanish-source employment income at a flat 24% up to €600,000, generally exempts foreign income and assets, and waives Modelo 720, for the year you arrive plus five more. Our guide to Europe's 15 special tax regimes covers where it ranks. And citizens born in Latin America or the Philippines naturalize after just 2 years of residency, versus 10 for everyone else. Under 90 Schengen days a year on a US passport, Spain costs you nothing at all: no tax residency, no Modelo 720, all of the lifestyle.
The verdict, by profile
- Second citizenship for your children, no long-term base: Mexico and Brazil are both excellent, and worth using tomorrow
- Canada and the UK: no, for really any reason
- Born a Latin American or Filipino citizen, or indifferent to taxes: Spain is an incredible option
- Tax-minimizing American: Spain is workable only short term, six years under the Beckham Law, no más
