What Actually Changes When You Leave the US

The United States taxes people on citizenship, not residence. It is one of only two countries in the world — the other is Eritrea — that does this. That single fact is the biggest difference between an American emigrant and a Canadian or British one: they file a final “departure” return and stop; you keep filing a US return for life, wherever you live. The good news is that filing rarely means paying. The move breaks into four questions, and none of them is about which country has the nicest beaches.

1. You never stop filing US taxes

Moving abroad does not end your obligation to file a US tax return, and it does not end it even in a year when you owe nothing. As long as your income is above the normal filing threshold, the Form 1040 follows you, along with the FBAR and possibly Form 8938. The two most common — and most expensive — mistakes are assuming you do not have to file because you live abroad, or because you already paid tax in your new country. Both are wrong, and skipped returns trigger penalties that compound quickly.

2. But you probably owe little: the FEIE and Foreign Tax Credit

Two mechanisms stop most expats being taxed twice. The Foreign Earned Income Exclusion (FEIE) lets you exclude foreign earned income — salary, self-employment — up to $130,000 for the 2025 tax year, rising to $132,900 for 2026. To claim it (on Form 2555) you must pass either the Physical Presence Test — 330 full days outside the US in a 12-month window — or the Bona Fide Residence test. Separately, the Foreign Tax Credit gives you a dollar-for-dollar US credit for income tax you have paid to your new country, which is what shelters pensions, dividends and other unearned income the FEIE does not cover.

3. Social Security abroad — paid everywhere, and the totalization split

US Social Security is the mirror image of the frozen UK pension story. As a US citizen you can collect it in almost every country — only Cuba and North Korea are blocked — and it keeps its annual cost-of-living increase. What varies by destination is a subtler thing: whether the country has a Social Security totalization agreement with the US. There are 14 among the destinations on this page and 13 without one (see the table). An agreement matters most if you are self-employed: without it you can be forced to pay into both systems — the local one and the 15.3% US self-employment tax — on the same income. With one, you pay into just one country’s system and carry a certificate of coverage to prove it.

4. Your foreign accounts must be reported — FBAR, FATCA and PFICs

Opening a bank account in your new country triggers US reporting. If your non-US financial accounts total more than $10,000 at any point in the year — added together, not per account — you must file an FBAR (FinCEN Form 114) by 15 April (auto-extended to 15 October), separately from your tax return. A higher-value Form 8938 (FATCA) may also apply. The sharper trap is the PFIC rule: most foreign pooled investments — local mutual funds, and pension wrappers like Australian superannuation, KiwiSaver or ISA-style accounts — are taxed punitively by the US unless handled carefully. Each country guide flags its own version.

And a few practical American details

Your police check is an FBI Identity History Summary — not the UK’s ACRO or Canada’s RCMP report, whatever a generic expat blog tells you. Documents for your destination are legalised with an apostille from the Secretary of State (state-issued documents) or the US Department of State (federal ones); a handful of countries outside the Apostille Convention still need full consular legalisation. And unlike Canada, the US has no departure or exit tax for ordinary movers — the expatriation tax only bites if you formally renounce citizenship as a “covered expatriate.” Moving keeps you fully inside the US system, which is exactly why the four questions above matter.

The two right-hand columns are the ones no cost-of-living list will tell you: whether the country has a US Social Security totalization agreement, and whether it has a US income-tax treaty. Income figures are approximate and are carried from each country guide — verify at the official consulate before applying.
