US expat taxes: Americans abroad still file
The United States taxes its citizens wherever they live. Moving to a low tax country changes the bill, but you keep filing. The United States is one of very few countries that tax citizens on their worldwide income wherever they live, so an American executive compares countries differently from everyone else. Moving to a zero tax country does not take the bill to zero: earned income above the 2026 exclusion of $132,900 stays taxable in the US, and investment income stays outside the exclusion. In a high tax country, the foreign tax credit usually removes the US bill on salary but gives you no saving against the local tax. So the real gain from moving tends to sit in the gap between the US rate and the local rate, and only when the local rate is the lower one.

| Salary excluded, 2026 cap | $132,900 / $132,900 |

| Salary left taxable | $67,100 |
| Tax with the exclusion | $12,240 |
| Tax with the credit | $36,734 |
Single filer, salary only, 2026 federal scale and standard deduction. With the exclusion, the rest is taxed at the rate it would have had without it. The credit is shown without its limits by income category, which can reduce it. Dividends, interest and capital gains stay outside the exclusion.

| A country with no income tax | Exclusion | US tax above $132,900 and on investment income |
| A country taxing less than the US | Compare both | A US top-up on the difference |
| A country taxing more than the US | Foreign tax credit | The local tax, which is the higher one |
The exclusion
For 2026 you can exclude up to $132,900 of foreign earned income, against $130,000 for 2025. To qualify you must be a genuine resident abroad for a period that includes a whole tax year, or be physically in foreign countries for at least 330 full days in any 12 consecutive months.
It covers earned income, such as a salary. Dividends, interest and capital gains stay outside it.
The credit
The foreign tax credit reduces your US tax by the foreign income tax you paid on the same income. Where the local tax is higher than the US bill, as in much of Western Europe, the credit often does more than the exclusion. In a country with no income tax there is nothing to credit, so the exclusion does the work and income above the limit is taxed by the US.
Dates that catch people out
Returns are due on 15 April. If your tax home and your abode are both outside the United States on that date, you get an automatic extension to 15 June to file, but interest on any tax due still runs from 15 April. Paying late therefore costs money even with a valid extension.
The first year needs planning, because the residence test requires a whole tax year and you may not meet it by June. Form 2350 asks for more time, generally until 30 days after you can reasonably expect to qualify, and must be filed by the due date of the return.
The small print of the exclusion
You also need a tax home in a foreign country, and the 330 days need not be consecutive. War or civil unrest can waive the minimum period. Once chosen, the exclusion stays in force for later years until you revoke it, and if you revoke it you need IRS approval to choose it again within five years. So a switch to the credit in one good year is not a free move, and the choice should be worked out over several years.
Income you exclude cannot also carry a credit: no credit or deduction is allowed for foreign tax on excluded income, and if only part of your pay is excluded the tax is divided by a fraction. You can also treat some housing costs as excluded or deductible. The base amount is 16% of the maximum exclusion, $21,264 for 2026, and the usual limit on expenses is 30% of it, $39,870, prorated by days. Costly cities may have a higher limit, which we did not check city by city.
Self-employed, and social security
The exclusion does not reduce self-employment tax, and net earnings of $400 or more already require a return. Totalization agreements with some countries are there to stop you paying social security twice on the same work, so that you generally pay in one country only. Check whether your country has one before you assume either charge disappears. Only wages paid after the agreement took effect can be exempt.
A worked case: $180,000 in a country with no income tax
With no foreign tax to credit, the exclusion is the only tool. If you pass a test for all of 2026, $132,900 comes off and $47,100 stays taxable, at the rate it would have had without the exclusion rather than from the bottom of the scale. A bank account above $10,000 in total adds a separate FBAR filing. Enter your own salary in the simulator above to see the tax on each route.
Reading any country comparison
A ranking of countries, ours included, treats each country’s tax as final. For a US citizen it is not: on top of the local tax, a US bill can remain. Use a ranking to compare countries, then run your own US return before deciding.

Questions
How much can I exclude as a US expat in 2026?
Up to $132,900 of foreign earned income, if you pass the bona fide residence test or the physical presence test of 330 full days in any 12 consecutive months. It applies to earned income such as salary. Dividends, interest and capital gains stay outside it, so they remain taxable in the United States.
Do I still file a US return if I owe nothing?
Generally yes if your income is above the filing threshold, because the exclusion and the credit are both claimed on a return. Moving abroad does not end the obligation. Form 2555 claims the exclusion and Form 1116 claims the credit. Filing late can cost you the choice you wanted, so plan the first year abroad carefully.
Exclusion or foreign tax credit?
In a high tax country the credit is often better, because local tax already exceeds the US bill on your salary. In a zero tax country only the exclusion helps, since there is no foreign tax to credit, and income above the limit is taxed by the US. In between, run both on your actual figures before you choose.
