Retiring abroad early: cheaper tacos, same IRS

By Tom, CPA · Updated October 25, 2026

TL;DR: U.S. citizens owe U.S. tax on worldwide income even after retiring abroad. The foreign earned income exclusion only covers work income, so a portfolio-funded retiree gets little help from it; the foreign tax credit and treaties matter more. Foreign accounts above $10,000 in aggregate require an FBAR. Cut state ties cleanly, and plan health care, since Medicare usually doesn't cover care abroad.

Retiring early in a country where a nice apartment costs less than a U.S. car payment is one of the oldest geographic arbitrage tricks in the FIRE book. Lower costs can shrink a FIRE number dramatically.

The catch: the U.S. is one of very few countries that taxes citizens based on citizenship rather than residence. You can leave the country, but your Form 1040 comes with you. Here's what early retirees should know, as of Oct 2026. See also geographic arbitrage.

CPA Warning Label: Moving abroad may lower your rent, raise your paperwork and cause sudden fluency in the phrase 'certified copy.'

Citizenship-based taxation

U.S. citizens and green card holders are taxed on worldwide income regardless of where they live, per IRS Publication 54. Retirees abroad still file Form 1040 if their income meets the filing threshold, and report dividends, capital gains, interest, IRA and 401(k) withdrawals, Roth conversions, pensions and Social Security.

Your new country may also tax you as a resident. Many countries tax residents on worldwide income too, and some offer special regimes for foreign retirees. The foreign tax credit and tax treaties are the main tools to avoid paying twice. Treaties vary a lot, including how they treat pensions, Social Security and Roth accounts, so the host country's treaty is worth reading before choosing a destination.

Filing deadline note: Publication 54 explains that U.S. taxpayers living abroad on the regular due date get an automatic two-month extension to file, though interest still runs on unpaid tax.

FEIE doesn't cover investment income

The foreign earned income exclusion ($132,900 for 2026, per Rev. Proc. 2025-32) gets a lot of attention, but it only applies to earned income for work done abroad. A retiree living on a portfolio has little or none.

That means a FIRE retiree's U.S. tax picture abroad often looks a lot like it did at home: the same brackets, the same 0% long-term capital gains bracket and the same Roth conversion planning. The difference is the host country's tax layered on top. Barista-FIRE retirees who work part-time abroad can use the FEIE for that work income; see digital nomad taxes.

FBAR and FATCA

Once you open a local bank account for rent and groceries, two reporting regimes may apply:

• FBAR (FinCEN Form 114): required if the aggregate value of your foreign financial accounts exceeds $10,000 at any time during the year. It's filed electronically with FinCEN, separate from your tax return.
• FATCA Form 8938: filed with your return if specified foreign financial assets exceed thresholds that are higher for people living abroad and for joint filers.

These are reporting forms, not taxes, but penalties for missing them can be steep. A related practical issue: some foreign banks are reluctant to open accounts for Americans because of the reporting burden, and some U.S. brokerages restrict accounts for customers with foreign addresses. Ask before you move.

One more trap: foreign mutual funds and ETFs are often treated as PFICs under U.S. rules, with harsh tax treatment and complicated filing. Many American expats keep investing through U.S.-domiciled funds for this reason.

State residency exit

Moving abroad doesn't automatically end state residency. If your state still considers you domiciled there, it may tax your worldwide income too. States differ, and some are known for careful scrutiny of people who leave.

Steps people commonly take to show a clean break:

• Sell or rent out the home, or establish domicile in another state first
• Surrender the driver's license or move it to the new domicile state
• Update voter registration, car registration and mailing address
• Close local memberships and move professional relationships
• Keep a dated file of these changes

Some retirees establish domicile in a state without an income tax before leaving the U.S. See the no-income-tax states comparison and the state tax move calculator.

Health care

Health care is often the best and scariest part of retiring abroad. Many countries offer high-quality care at a fraction of U.S. prices, through public systems open to legal residents, private insurance or both.

Things to know:

• Medicare usually doesn't cover care outside the U.S., per Medicare.gov, with limited exceptions. Retirees who expect to return to the U.S. someday weigh whether to enroll in Part B at 65 anyway, because late enrollment penalties can apply.
• ACA marketplace plans are for U.S. residents. Moving back to the U.S. can open a Special Enrollment Period.
• International health insurance varies widely in age limits, exclusions and pre-existing conditions. Read the policy, not the brochure, and ask how premiums change after age 65 or 70.
• Public systems in some countries require residency registration and contributions before you can enroll.

Social Security abroad

U.S. citizens can generally receive Social Security payments in most foreign countries, but there are exceptions and restrictions for some countries. SSA's payments abroad screening tool lets you check a specific country. Totalization agreements may also help if you worked in a foreign country. Your host country may tax U.S. Social Security depending on its laws and the treaty.

Running the cost-of-living math honestly

A lower rent is the headline, but a fair comparison includes the costs that show up later:

• Visas and residency permits, which may require proof of income or savings and renewal fees
• Flights home for holidays, weddings and family emergencies
• Health insurance that rises with age
• Currency swings: if your portfolio is in dollars and your rent is in another currency, a weaker dollar raises your costs
• Tax prep for two countries, which is usually pricier than one

Many people do a trial run first, renting for a few months before selling anything. See the early retirement trial run guide.

Before-you-go checklist

1. Research the host country's residency tax rules and the U.S. treaty.
2. Decide your state domicile and document the change.
3. Confirm your brokerage will keep serving you with a foreign address.
4. Open a bank account plan and set an FBAR reminder.
5. Choose health coverage and decide on Medicare enrollment timing.
6. Check Social Security payment rules for the country.
7. Keep copies of key documents in secure cloud storage.

Illustration: Fran's move abroad

Illustration. Hypothetical: Frugal Fran, 45, retires to a country with lower living costs. She spends $36,000 a year funded by a taxable brokerage account and Roth conversions.

Her FIRE number fell because her expenses fell, not because her taxes vanished. Lavish Larry moved abroad too, then kept a U.S. apartment, a U.S. car and a U.S. gym membership, and his former state still considered him a resident. Larry is very consistent.

Renouncing citizenship is a big step

Some people ask whether giving up U.S. citizenship ends the tax issue. It's a serious, permanent decision with fees, an exit tax regime for some individuals, and immigration consequences. It's mentioned here only so you know it exists and is far beyond a budgeting decision. For nearly every early retiree abroad, the realistic plan is simpler: keep filing, keep records, use credits and treaties, and enjoy the cheaper tacos with a clear conscience and a well-organized folder.
