Do You Pay US Taxes If You Live Abroad?

You still pay US tax on worldwide income while you live abroad, and you still file when that income reaches the line for your status. For a single person under 65, Publication 501 puts that 2025 line at $15,750 of gross income. Wages you later exclude do not drop out of the test.

That is the expensive mix-up. Say you earned $90,000 abroad in 2025. That amount is over $15,750, so the return is required, and it is also under the $130,000 foreign earned income exclusion for that year, so the income tax on those wages can be zero if you qualify. Skipping the form because the exclusion wiped out the tax is how a clean year becomes a late return. Count the salary first, then use the other federal filings in Expat Tax & Finance, including the choice between excluding wages and claiming a foreign tax credit.

Do you still file if you owe nothing?

Yes, once worldwide gross income hits your row on the chart. The Internal Revenue Service says citizens and residents outside the country generally file income, estate, and gift returns, and pay estimated tax, the same way people living in the United States do. Owing nothing at the end is not the test. Crossing the gross-income line is.

The IRS filing page for citizens abroad is explicit about excluded pay. When you decide whether a return is required, you count income you exclude as foreign earned income or as a foreign housing amount. A salary that Form 2555, Foreign Earned Income, later removes from taxable income is still gross income for this first question. Self-employed gross income is the Gross Income line on Schedule C, not the profit left after every expense.

Report every figure in US dollars. If the salary landed in euros or pesos, translate it before you compare it with the dollar line. The filing page does not let you leave the return in foreign currency.

Which gross-income line applies?

Use the 2025 chart in Publication 501 for the return that covers 2025. Age is measured at the end of that year. As of October 2026, this is the filing table the IRS is publishing. The 2026 standard deduction is a different number, and it is not a substitute for this chart.

Filing status	Age at the end of 2025	File if gross income is at least
Single	Under 65	$15,750
Single	65 or older	$17,750
Head of household	Under 65	$23,625
Head of household	65 or older	$25,625
Married filing jointly	Both under 65	$31,500
Married filing jointly	One spouse 65 or older	$33,100
Married filing jointly	Both 65 or older	$34,700
Married filing separately	Any age	$5
Qualifying surviving spouse	Under 65	$31,500
Qualifying surviving spouse	65 or older	$33,100

Data note: dollar lines are from Publication 501 for tax year 2025, checked in October 2026. They move with the standard deduction.

Social Security and the filing line

Publication 501 tells you to leave Social Security benefits out of gross income for this test unless one of two things is true. The first is that you are married filing a separate return and you lived with your spouse at any time during 2025. The second is that half of your benefits, plus your other gross income and any tax-exempt interest, is more than $25,000, or more than $32,000 if you file jointly. If either condition applies, you include the taxable part figured under the Form 1040 instructions, not the whole check.

A retiree whose only cash is a modest benefit can be under the filing line. A retiree with a pension, rent, or a large benefit often is not, because the half-plus-other-income test pulls benefits back in. How much of the benefit is taxed after you do file is a different worksheet, walked through in whether Social Security is taxable while you live abroad.

Married filing separately is a $5 test

The joint rows are the household numbers. Married filing separately is $5 of gross income at any age. Expats use that status when one spouse is a nonresident and they do not want a joint return. Five dollars of interest is enough to require a separate return. Do not borrow the $31,500 joint line for a separate filing.

Add wages, interest, dividends, rent, and business gross income from anywhere. Include the gain on a sale, not the loss. If you are close to the line, translate the foreign amounts and then compare. A penalty can apply when a required return is never filed. Publication 501 says that in plain words and does not give you a foreign-address exception.

Does the exclusion cancel the return?

No. The IRS calls it a common misconception that excluded income does not have to be reported. On the page that explains the foreign earned income exclusion, the exclusion applies only if you qualify and you file a return that reports the income. The form that claims it is Form 2555.

For tax year 2025 the ceiling is the lesser of your foreign earned income or $130,000 per qualifying person. For tax year 2026 it is $132,900 per person. If you and your spouse both work abroad and each meets the bona fide residence test or the physical presence test, each may claim the exclusion. Together, the 2025 cap the IRS states is $260,000. Earned income is the pay for work. The exclusion is not a blanket over every deposit.

You still have to meet a test. Bona fide residence and the physical presence test are the two doors, and a partial year is prorated. The IRS walks through someone who established a tax home and bona fide residence on 14 August 2025 and kept it into 2027. That person has 140 qualifying days in 2025, and the maximum exclusion for that year is $49,863, which is 140 divided by 365, times $130,000. A move in August does not give you the full $130,000.

Exclusion or credit, after you know you must file

Once the return is required, the next cash question is which relief you claim. The exclusion removes qualifying earned income. The foreign tax credit reduces US tax by income tax paid to the other country. They do not do the same job, and using the exclusion can change later credits. Compare them in the foreign earned income exclusion versus the foreign tax credit before you lock Form 2555 for a high-tax country.

For money you are earning now, the IRS inflation release sets the 2026 exclusion at $132,900 and the 2026 standard deduction at $16,100 for single filers, $32,200 for a joint return, and $24,150 for head of household. Those deduction figures are for the return filed in 2027. Keep the $15,750 chart for the 2025 return. Do not swap in $16,100 and call it the filing line until the IRS publishes that year's chart.

When does $400 of profit force a return?

When net earnings from self-employment are at least $400. The IRS page on self-employment tax abroad says the rules are the same whether you live in the United States or outside it. The foreign earned income exclusion does not shrink that base. You count the self-employment income even if you excluded the gross receipts.

The IRS example is a consultant abroad who qualifies for the exclusion. Foreign earned income is $95,000, business deductions are $27,000, and net profit is $68,000. Self-employment tax is due on all $68,000 of that profit, even if the exclusion removed the income tax. That profit is also far above $400, and the Schedule C gross income is far above $15,750, so both the income-tax filing line and the self-employment line are met.

A smaller freelance year

Say your Schedule C gross income for 2025 is $8,000 and your net profit is $2,000, with no other income. The $8,000 gross-income figure is under the $15,750 single line, so that row alone would not require a return. The $2,000 net is over $400, so self-employment tax still requires the return and Schedule SE. People who invoice a few clients from a laptop abroad trip over this one more often than they trip over $15,750.

If you expect to owe $1,000 or more when you file, estimated tax is the way the IRS collects income tax and self-employment tax during the year. Most people avoid the underpayment penalty if they owe less than $1,000 after withholding and credits, or if they paid at least 90 percent of the current-year tax or 100 percent of the prior-year tax, whichever is smaller. You can skip estimates for the current year if you had no tax liability last year, you were a citizen or resident alien all year, and that prior year was a full 12 months. Higher-income taxpayers use extra rules in Publication 505.

When do you pay, and when do you file?

The automatic extra two months move the filing date. They do not freeze interest. If on the regular due date you live outside the United States and Puerto Rico and your main place of business or post of duty is also outside the United States and Puerto Rico, the IRS automatic-extension page gives you until 15 June for a calendar-year return. The regular due date is still 15 April. Interest runs on tax unpaid at that April date. Attach a statement that says which condition you met.

On a joint return, either spouse can qualify for those two months. On separate returns, only the spouse who qualifies gets them. If 15 June falls on a weekend or a legal holiday, the date moves to the next business day. Need longer to file? Form 4868, filed before the June date, asks for another four months. That extra time is for the paperwork. It is not more time to pay.

Close the year in this order

1. Translate worldwide income into US dollars, and keep wages you plan to exclude inside the total.
2. Pick the Publication 501 row for your status and your age at year-end. Married filing separately stops at $5.
3. If you have a business, read Schedule C gross income and test net earnings against $400.
4. If you will owe $1,000 or more, pay estimates. Do not wait for 15 June to send tax that was due 15 April.
5. If you use the two-month extension, attach the statement. If foreign accounts together exceeded $10,000 on any day, file FinCEN Report 114 as well. That report is not part of Form 1040.

The $10,000 figure is an aggregate of foreign accounts, at any point in the year, and it includes signature authority, not only accounts you own outright. FinCEN's FBAR page is the rule. A balance that never crossed $10,000 does not need the report. Crossing it for a day does.

Living abroad changes the address on the envelope. It does not switch off the US return. File when the chart or the $400 test says so, claim the exclusion only on a return that reports the wages, and pay anything still due on the April date so June is a filing extension rather than a surprise interest bill.

Data notes

Rules and dollar amounts were checked in October 2026 against primary pages:

• IRS, US citizens and residents abroad, filing requirements, including the rule that excluded foreign earned income still counts toward the filing line.
• Publication 501 (2025), the gross-income filing chart, the Social Security footnote, and the $5 separate-return line.
• IRS, figuring the foreign earned income exclusion, the $130,000 and $132,900 caps, the $260,000 figure for two working spouses in 2025, and the 140-day example.
• IRS newsroom, tax year 2026 inflation adjustments, the 2026 standard deduction and the $132,900 exclusion.
• IRS, self-employment tax for businesses abroad, the $400 test and the $95,000 consultant example.

• IRS, estimated taxes, the $1,000 rule.
• FinCEN, Report of Foreign Bank and Financial Accounts, the $10,000 aggregate test.

The 2026 filing-threshold chart was not published on the Publication 501 page used here. State returns follow state rules and are not in these federal lines. Thresholds, interest, and the exclusion amount change. This is not tax or legal advice. Confirm the chart for the year you are filing and talk with a qualified tax professional before you rely on the exclusion, a totalization certificate, or a decision not to file.
