How Much Do You Have to Make to File Taxes in 2026? A Complete Guide for U.S. Expats

”How much do I have to make to file taxes?”

For Americans living abroad, this is one of the most common and most misunderstood questions about U.S. tax filing. Many expats assume that moving abroad changes the rules or eliminates the filing requirement altogether. It doesn’t. Americans abroad are subject to the same filing rules as taxpayers living in the United States.

The filing requirement depends on a few specific factors, including your filing status, age, and the type of income you receive. What it does NOT depend on is where you live.

This guide explains how those rules apply when filing a 2025 tax return in 2026, clears up common expat misconceptions, and shows when filing is required even if no U.S. tax is ultimately owed.

Worldwide Income Rules for Expats

Living abroad does not change your U.S. tax filing obligation. As a U.S. citizen or resident alien, you remain subject to U.S. tax law, including annual filing requirements.

In general, the IRS requires you to file a federal tax return once your gross income reaches a certain level based on your filing status and age. Gross income means your total income from worldwide sources, calculated before deductions, exclusions, or credits.

This point matters because many expats conflate owing tax with having to file. They are not the same.

Foreign income, foreign taxes paid, and expat tax benefits do not remove the filing requirement. Exclusions and credits apply after you file. If your income meets the filing threshold, filing is mandatory even if your final U.S. tax bill ends up at zero.

What Counts as Income for IRS Filing Purposes?

To determine whether you must file, the IRS looks at gross income, not taxable income.

Earned Income

Earned income includes compensation for work you perform, such as:

• Wages or salary from a U.S. or foreign employer
• Self-employment income
• Freelance or contract work
• Professional services performed overseas

If you worked while living abroad, that income counts toward your filing requirement, regardless of where the employer is based or where the money was paid.

Unearned Income

Unearned income does not come from work. Common examples include:

• Interest and dividends
• Rental income
• Capital gains
• Pension or retirement distributions
• Investment income earned overseas

Unearned income often triggers filing requirements earlier than earned income, particularly for retirees and dependents.

How Much Do You Have to Make to File Taxes If You Live Abroad?

The IRS sets income thresholds to determine who must file a tax return and updates them annually to reflect inflation.

If your gross income meets or exceeds the amount tied to your filing status and age, you must file a tax return.

For the 2025 tax year (returns filed in 2026), the thresholds are:

Single Filers

• Under age 65: $15,750
• Age 65 or older: $17,750

Married Filing Jointly

• Both spouses under 65: $31,500
• One spouse 65 or older: $33,100
• Both spouses 65 or older: $34,700

Married Filing Separately

• Any age: $5

This low threshold often affects expats with nonresident alien spouses or spouses living in different countries.

Head of Household

• Under age 65: $23,625
• Age 65 or older: $25,625

Qualifying Surviving Spouse

• Under age 65: $31,500
• Age 65 or older: $33,100

These thresholds apply to your total worldwide income, not just U.S.-source income.

Do You Have to File If You’re Self-Employed Abroad?

Self-employment income is subject to different filing rules, which often surprises expats.

If you earn $400 or more in net self-employment income, the IRS requires you to file a U.S. tax return. This rule applies regardless of where you live, your age, or your filing status.

Net self-employment income means your profit after business expenses, not your total revenue.

For example, if you earn $5,000 from freelance work abroad and deduct $4,700 in expenses, the remaining $300 does not trigger a filing requirement. But once your net profit reaches $400, filing becomes mandatory.

Self-employed expats may also owe self-employment tax, even when income tax is reduced or eliminated through exclusions or credits.

Those tax funds U.S. Social Security and Medicare and follows different rules than income tax.

Do Dependents Living Overseas Have to File U.S. Taxes?

Possibly. Dependents follow different filing rules than independent taxpayers, and those rules depend on how much they earned and the type of income they received.

For dependents, the IRS looks at earned income, unearned income, and a combination of both. Living overseas does not change these thresholds.

For the 2025 tax year (returns filed in 2026), a dependent generally must file a U.S. tax return if any of the following apply:

1. Earned Income Exceeds the Dependent Standard Deduction

If a dependent’s earned income, such as wages, salary, or self-employment income, exceeds $15,750, filing is required.

This applies even if the work was performed overseas and the income came from a foreign employer.

2. Unearned Income Exceeds IRS Limits

If a dependent’s unearned income, such as interest, dividends, or investment income, exceeds $1,300, filing is required.

Unearned income often triggers filing at much lower levels than earned income, which is why dependents with savings accounts or investment portfolios frequently need to file even if they did not work during the year.

3. Combination of Earned and Unearned Income Crosses the Applicable Threshold

If a dependent has both earned and unearned income, filing is required when the total income exceeds the greater of:

• $1,300, or
• Earned income plus $450, up to the standard deduction limit of $15,750

As with all other filing rules, these thresholds apply to worldwide income. A dependent living, studying, or working abroad follows the same IRS standards as a dependent living in the United States.

Do You Have to File If Your Only Income Is Social Security?

You generally don’t need to file a tax return if Social Security is your only income. However, filing becomes necessary once Social Security combines with other income, including:

• Foreign wages
• Pension income
• Interest or dividends
• Tax-exempt interest

When combined income crosses IRS limits, a portion of Social Security benefits becomes taxable, and filing is required.

Do You Still Have to File If You Don’t Owe Any U.S. Tax?

In many cases, you still must file even when your final U.S. tax bill is zero.

Many expats reduce or eliminate U.S. income tax by claiming:

• The Foreign Earned Income Exclusion
• The Foreign Tax Credit
• Standard deductions and applicable credits

None of these benefits applies automatically. You must file a tax return to claim them. If your income meets the filing threshold, you must file regardless of how much tax you ultimately owe.

There’s also a long-term reason why filing matters. The IRS statute of limitations does not start until a return is filed. When you don’t file, prior years remain permanently open to review. That exposure exists even if no tax was due.

What Happens If You Should Have Filed but Didn’t?

Not filing doesn’t automatically result in penalties or criminal exposure. Many expats fail to file simply because they misunderstood the rules or believed filing wasn’t required.

When a failure to file is unintentional, the IRS offers voluntary compliance options, such as the Streamlined Filing Compliance Procedures, that allow taxpayers to correct past filing issues before the IRS initiates contact.

Coming forward voluntarily limits penalties, reduces interest, and lowers overall risk. However, waiting to address the issue can lead to a very different outcome.

Once the IRS initiates contact, relief options narrow, and the cost of resolving the issue typically increases.

Frequently Asked Questions

1. Do I still have to file a U.S. income tax return even though I don’t live in the United States and pay income tax in a foreign country?

Yes. U.S. citizens and green card holders are required to file U.S. tax returns based on citizenship, not residence. Paying tax to another country does not eliminate the U.S. filing requirement. Instead, relief usually comes through exclusions, credits, or treaty provisions claimed on a filed return.

2. Do I have to file if my income is under the Foreign Earned Income Exclusion?

Yes. You must file a U.S. tax return to claim the Foreign Earned Income Exclusion. The exclusion can reduce or eliminate U.S. tax, but it does not remove the obligation to file. Without filing, the IRS does not recognize the exclusion at all.

3. How many years back do I have to file if I haven’t filed taxes for years?

There is no automatic cutoff for unfiled tax returns. In many cases, the IRS allows taxpayers to come into compliance by filing a limited number of prior-year returns under approved programs. The number of years required depends on your facts, income, and filing history.

4. Do I have to file if I only earned foreign income?

Yes. The IRS taxes U.S. citizens on worldwide income, regardless of where it was earned. Foreign income still counts toward U.S. filing thresholds. Whether you owe tax is a separate question from whether you must file.

5. Should I file even if I don’t owe U.S. tax?

Often, yes. Filing starts the statute of limitations and protects you from future questions about unfiled years. It also preserves your ability to claim refunds, credits, and exclusions.

6. What if I didn’t know I had to file while living abroad?

Many expats fail to file simply because they misunderstood the rules. The IRS offers voluntary compliance options for taxpayers who unintentionally failed to file. Addressing the issue early keeps options open and limits cost and exposure.
