The process of filing taxes in the US as an expat can seem overwhelming, but don’t worry—we’ve got you covered. Whether you’re navigating double-taxation concerns, figuring out deductions, or trying to meet IRS deadlines, this guide will simplify everything you need to know.
For any American resident or expatriate living abroad, filing a US income tax return is usually mandatory. But the bright side? There are exemptions, deductions, and credits available that can help make your tax bill significantly lighter.
Do I Have to File a US Income Tax Return as an American Living Abroad?
Short answer? Yes. Even if you’re outside of the US, the IRS requires all citizens and green card holders to report their worldwide income annually. This obligation exists regardless of where you live or where your income is earned.
Many expats are surprised to learn this! It’s not uncommon for Americans abroad to miss filing deadlines simply because they weren’t aware of the requirement. That said, failing to file your taxes can lead to penalties down the line.
If you’re unsure whether you need to file, visit the IRS website and consult a tax specialist to understand your obligations.
Who Is Considered a US Resident?
The IRS uses the Substantial Presence Test to determine residency. You qualify as a US resident for tax purposes if you were present in the country for either:
- At least 31 days during the current tax year, and
- A total of 183 days over the last three years (calculated using a formula).
For example, if you visited the US often for business in prior years, you may still meet the substantial presence rule—even if you reside abroad.
Who Is Exempt From Filing Their 2025 US Taxes?
Certain groups are exempt from filing a tax return with the IRS. These include individuals whose annual worldwide income falls below specific thresholds or those who qualify under special exceptions (e.g., qualifying dependents).
For example, for the 2024 tax year (filed in 2025), single taxpayers need not file if their income is below $12,950. Check the latest thresholds on the IRS website to confirm.
Will I Be Double-Taxed on My Worldwide Income?
Here’s the good news: No, most US expats are not double-taxed on their income. Due to international agreements and tax relief policies, the IRS offers credits and exemptions to prevent double taxation.
This means that while you have to report your income, you can often offset foreign taxes paid to your host country.
Tax Relief Options for Expats:
- Foreign Earned Income Exclusion (FEIE): This allows you to exclude $120,000 of foreign-earned income annually (as of 2023).
- Foreign Tax Credit: Claim credits for taxes already paid to another country.
- Foreign Housing Exclusion: Deduct specified housing expenses while living abroad.
By leveraging these options, most expats don’t owe any additional US taxes, though they must still file a return.
How Do I File My US Taxes from Abroad?
Filing taxes while living overseas involves many of the same steps as filing from within the US. Here’s how to get started:
- Complete Form 1040: This is the standard form for reporting income.
- Attach Required Schedules: For instance, if claiming FEIE, include Form 2555.
- Submit Online or by Mail: You can file digitally using IRS-approved software or send your forms to the proper IRS address for international filers.

What Foreign Income Should I Declare on My US Tax Return?
When filing as an expat, you need to declare all worldwide income, including but not limited to:
- Salaries, freelance income, or rental income earned overseas.
- Interest earned on foreign bank accounts totaling over $10,000 USD.
- Dividends or stock sales if foreign holdings gain value against the USD.
Important tip: Convert all figures to USD when filing, using the applicable exchange rates.
US Tax Brackets for 2024
Tax brackets for filing in 2025 are:
- 12% on income up to $11,600, or $23,200 for married couples filing jointly.
- Rising incrementally to a top rate of 37% on annual income above $609,350 for individuals (or $731,200 for joint filers).
Details for marginal tax rates can be found on the IRS’s official page.
When Is My US Tax Return Due If I File as an Expat?
The standard tax return deadline is April 15, 2025, for reporting incomes earned in 2024.
However, Americans abroad receive an automatic extension until June 16, 2025. If you need more time, you can request an additional extension, giving you until October 15, 2025 to file. Keep in mind interest accrues on any unpaid tax amounts after April.
When and How Do I Pay My US Taxes from Abroad?
Taxes are due by April 15, even if you’ve filed for an extension. Payment options for expats include:
- Electronic Federal Tax Payment System (EFTPS) for US account holders.
- Sending a wire transfer directly to the IRS.
- Paying with credit or debit card.
If you’re unable to pay in full, contact the IRS immediately to arrange a payment plan.
Handling Late Returns and Penalties
Missed a deadline? The IRS imposes penalties for late filings or payments:
- 5% penalty for every month a return is late (up to 25%).
- Minimum penalty on delayed filings of $450 USD or 100% of unpaid taxes, whichever is less.
To avoid these penalties, file even if you owe nothing!
Planning for Taxes When Leaving or Returning to the US
Leaving the US
Planning to move abroad? Review how your assets—including property and any retirement accounts—will be taxed. Consulting a tax advisor ensures proper preparation so you can avoid unnecessary financial stress.
Returning to the US
When moving back, your filing requirements revert to those of a US resident. For partial tax years spent abroad, you’ll need to calculate prorated deductions like FEIE.
Renouncing US Citizenship
Some Americans choose to renounce their citizenship or permanent residency to avoid future tax obligations. Be mindful that this comes with Expatriation Tax and requires filing Form 8854.
Stay Ahead of Your Expat Taxes!
Successfully filing taxes as an expat requires diligence, preparation, and guidance. With proper planning and use of tax relief programs like the FEIE, you can meet IRS requirements without undue stress.
