Filing US Taxes Living Abroad: What You Need to Know

There are many things you can outrun, but paying taxes to the US government isn't one of them. Living abroad doesn't exempt you from US tax obligations, even if you haven't set foot on American soil for years. This may come as a shock, especially if you're already paying taxes where you live. However, American citizens and permanent residents must report worldwide income, regardless of where they live. 

Understanding how to handle taxes when living abroad is the key to avoiding IRS penalties. This guide will teach you everything you need to know about filing US taxes abroad, including deadlines, forms to file, and how to reduce double taxation.

Filing Requirement for US Citizens and Residents Abroad

Worldwide Income Reporting

If you're a US citizen or resident alien, your worldwide income is subject to income tax regardless of where you're living. You're also subject to the exact income tax filing requirements that apply to resident aliens or US citizens living in the United States. 

Filing Thresholds for 2024/2025

The IRS requires you to file your income tax returns if your gross income meets or exceeds the standard deduction. Here are the 2024/2025 filing thresholds:

Filing status	2024 tax year	2025 tax year
Single	$14,600	$15,750
Married, filing jointly	$29,200	$31,500
Married, filing separately	$5	$5
Head of household	$21,900	$23,625

These thresholds apply to all your income, regardless of where you earn it. It includes business income, dividends, rental income, wages, etc. If you're self-employed and you earn $400 or more (net income), you're required to file an income tax return, even if it's all foreign income. There are also other special situations where you may need to file a return, even if your income is below the standard deduction – check out the IRS filing requirements for individuals.

Deadlines and Extensions

If you're a US citizen living abroad, the tax you owe is due April 15th, following the year you earned the income. However, you automatically receive a two-month extension to file your federal tax return, so you have until June 15 to submit Form 1040. This extension doesn't require you to submit any paperwork, and it's completely free. 

Note that the deadlines move to the next business day if they fall on a weekend or holiday. For example, taxpayers who live abroad have a deadline of June 16th, 2025, to file their 2024 income tax returns.

FATCA forms ( like Form 8938) are due the same day as your tax return, including any extensions you've requested. The deadline to file your FBAR ( FinCEN Form 114) is April 15, but you get an automatic extension until October 15.

If you still can't file your returns even with the automatic extensions, you can request an additional extension by filing Form 4868 by June 15. This could be because you need to reconcile your foreign income with US returns, or you're waiting for foreign tax documents from your host country. Keep in mind that an extension to file your returns doesn't mean an extension to pay your taxes. 

Key Tax Benefits and Exclusions

Leveraging the tax exclusions, deductions, and credits you qualify for can help reduce your US tax bill. Here are some tax benefits and exclusions to consider:

Foreign Earned Income Exclusion (FEIE)

If you qualify for FEIE, you can deduct up to $130,000 of foreign income for the 2025 tax year. However, only earned income qualifies for the FEIE. Earned income includes salary, wages, bonuses, self-employment income, etc. Capital gains, annuities, alimony, lottery winnings, rental income, and dividends are considered passive/unearned income, and they're ineligible for FEIE. 

Also, before you claim foreign earned income, ensure you meet one of these tests:

• The physical test: To meet this test, you must be physically present in a foreign country or countries for at least 330 days out of 365 days. These days don't have to be consecutive, but only days that are spent a whole 24 hours outside the US count as a full day. 

• The bona fide residence test: To pass this test, you must be physically present in a foreign country for a full tax year. 

You can claim for FEIE by filling out Form 2555.

Foreign Housing Exclusion/Deduction

If you qualify for FEIE, you may also be eligible for Foreign Housing Deduction (FHD – for self-employed), or Foreign House Exclusion (FHE – for employees). You may only claim this deduction if your employer paid for your housing with taxable income or you paid for it with self-employment income. To determine how much you calculate for housing, the IRS subtracts the base rate from your total eligible housing amount before allowing any exclusions. 

This base in 2025 is 16% of the $130,000 FEIE, which is $20,800. The IRS has a maximum cap of 30% of the FEIE per year ($39,000 in 2025).

For example, let's say you spend $40,000 on eligible housing expenses. To determine your deduction, you subtract the base amount from your eligible expenses: $40,000 – $20,800. Then, the difference $19,200 is your deduction. If the calculation exceeds the max cap, you should claim that amount. These calculations can get more complex if you spend time away from your foreign home – in that case, you'll need to break down the deduction by daily expenses. 

Note that the base housing amount can differ from one location to another. If you're in a high-cost city such as Hong Kong, you might be eligible for a higher exclusion than expats living in lower-cost regions. 

Foreign Tax Credit (FTC)

The FTC allows you to claim dollar-for-dollar US tax credits on any foreign income taxes you've paid, as long as that country has a tax treaty with the United States (which most countries do). To qualify, taxes must be paid or accrued, payable by you, and based on income. For example, if you pay $10,000 in income tax to France, you can claim a $10,000 credit against your US-income tax owed.

Unfortunately, you can't claim the FTC on taxes you've paid on income excluded under the FEIE. On the bright side, you can claim the FTC on different types of income. For example, even though you can't claim taxes paid on unearned income like dividends or rental income on FEIE, you can claim that tax under FTC. 

If claiming the FTC lowers your tax bill than FEIE, it's beneficial to forego FEIE and claim the FTC. Here are some cases where claiming the FTC is better: 

• You have a high passive income. 
• Your foreign-earned income exceeds the FEIE threshold.
• Your foreign housing expenses are so low, and the benefit from FHE/FHD doesn't make a difference. 
• You live in a country with a higher tax rate than the US. In this case, the FTC eliminates your US tax bill and leaves you with tax credits you can redeem in the future. 
• The FEIE reduces your Adjusted Gross Income (AGI) to an extent where you don't qualify for other beneficial tax credits. 

A tax professional can help you create the best strategy for your tax situation. 

Tax Credits and Deductions Not Available to Expats

Unfortunately, living abroad prevents you from claiming some federal tax credits, including the following.

Earned Income Tax Credit (EITC)

As an expat, if you qualify for FEIE, it automatically disqualifies you from claiming EITC. To be eligible for EITC, you must have lived in the US for more than 183 days of the filing year. It becomes unavailable when using FEIE to reduce your taxable income. 

Education Credits

Technically, as an expat, you can claim education tax credits. The two common ones are the American Opportunity Tax Credit( AOTC) and the Lifetime Learning Credit ( LLC). There's only one major setback: the IRS only allows tax credits for education expenses if you're studying in an eligible foreign institution. Unfortunately, most foreign schools are not listed, so the credits are available in theory but unusable in reality. 

Child and Dependent Care Credit

The eligibility criteria for claiming the child and dependent care credit abroad are the same as those in the US, which is part of the problem. Whether you live abroad or in the US, you'll require a Taxpayer Identification Number (TIN) for both you and your care provider. If a care provider is from a foreign entity, then they don't have a TIN, meaning you don't have the necessary documentation and can't claim the credit. 

Reporting Foreign Financial Assets

Filing returns is just one of the obligations the US government requires from you as an expat; you still need to provide further financial information. Here is more reporting you should know about: 

FinCEN Form 114 (FBAR)

If you have one or more foreign financial accounts and at any point during the reporting year and the amounts in your accounts exceed $10 000, you must file an FBAR (a report of Foreign Bank and Financial Accounts). 

Financial accounts include deposits, brokerage accounts, savings accounts, mutual funds, checking accounts, and insurance policies with a cash value. 

FBAR forms are filed separately from your tax return, and should be submitted to the Financial Crimes Enforcement Network (FinCEN). You can submit it electronically using FinCEN's BSA E-Filing System. The official filing date is April 15, but again, you get an automatic extension until October 15. 

Form 8938 (FATCA)

You need to report on your foreign assets if their value exceeds a certain threshold. If you're a single filer living abroad, the threshold is $300,000 in foreign assets held at any point during the year or $200,000 at the end of the year. If you're filing jointly with your spouse, the threshold is $400,000 at the end of the year or $600,000 at any point during the year. 

FATCA is submitted on Form 8938, along with your annual tax return. 

Penalties for Non-Compliance

It's essential to file the required forms to avoid penalties. For example, FBAR was introduced in the 1970s to prevent criminal activities, tax evasion, and money laundering. Enforcement is very strict now, and not complying can attract a fine of up to $10,000 or higher, as this number is indexed to inflation – read more about FBAR penalties here.

Potential Tax Issues and Need for Resolution Assistance

Taxpayers who live abroad face special tax issues. TaxCure makes it easy to find a pro with the right experience – just start your search and then use the filters to narrow down the results.

Double Taxation Concerns

The US is one of the few countries that requires its citizens to pay their taxes regardless of where they decide to live in the world. Since the country you move to will require you to pay taxes too, there's potential for double taxation. 

You can take advantage of FEIE, FTC, and tax treaties to avoid this and reduce your tax bill. 

Complexity of Foreign Tax Systems

While the FTC, FEIE, and tax treaties can help you avoid double taxation, the US tax law is complex, and it's easy to make costly mistakes. For example, you need to know when to file for FEIE instead of FTC and vice versa to take maximum benefit of the tax deductions. Consult with a tax pro to ensure you're getting the most benefit possible and avoiding unnecessary penalties and interest.

Unintentional Non-Compliance

As an expat, it's easy to miss filing some compliance documents unintentionally. There's a lot you need to keep up with, from tax returns, FBARs, to FATCA. Unfortunately, the government deals with non-compliance harshly, and not filing these reports can lead to significant penalties.

Recent Developments and Proposed Changes

The tax code is constantly changing, which is why it's critical to work with a professional.

Legislative Proposals

On December 18, 2024, US Representative Darin LaHood introduced the Residence-based taxation (RBT) for expats. This is different from Citizenship-based taxation (CBT), which requires expats to pay US taxes while paying taxes in the foreign countries where they reside. RBT would provide tax relief to US citizens living abroad by easing the filing process and significantly reducing the US tax liability. This proposal remains under review at the time of writing. 

Political Support

Donald Trump promised to end double taxation for US citizens living abroad if he won the elections. He has to work with Congress to amend the tax code, so it's a lengthy process. This would be a massive step toward bringing the US in line with the global standard of residence-based taxation. At the time of writing, this is still a nascent idea.

Best Practices for US Taxpayers Abroad

Here are a few tips to ensure you stay compliant with US tax laws as an expat:

• Maintain detailed records: Keep comprehensive records of your income, foreign tax payments, expenses, bank account balances, and travel dates. This ensures you don't miss anything when reporting your taxable income, which may attract fines later.

• Stay informed on tax obligations: Tax laws and regulations are bound to change. Stay up-to-date with the latest guidelines on expat taxation to avoid any fines.

• Consult tax professionals: Expat taxes are complex, and you can easily miss something, especially when you're new. Even understanding filing deadlines is a lot; the tax deadline is April 15, and although you get an extension to June 15, the taxes owed are still due on April 15. Consulting with a tax professional ensures you stay compliant and you take the maximum advantage of tax credits available to you.

Frequently Asked Questions (FAQs)

Do I need to file a US tax return if I pay taxes in my country of residence?

Yes, as long as you hold a US citizenship or you're considered a US person, you have to report your worldwide income annually to the IRS. It doesn't matter where you earn it or where you live. 

How can I avoid double taxation on my foreign income?

You can take advantage of the FEIE, FTC, and any tax treaties to reduce or eliminate US tax. There are rules regarding this, so talk to a professional to know which one is suitable for you. 

What happens if I don't report my foreign financial accounts?

Late and missed filings, even when you have zero tax due, can attract severe penalties. This is especially serious with failing to report foreign assets or accounts, which leads to very high penalties. 

Am I eligible for US tax credits while living abroad?

You may be eligible for some credits but not others. For example, you cannot claim the EITC unless you live in the United States for at least half the year. Many other US tax credits follow the same eligibility rules for expats, which can be a disadvantage because these rules often make it harder for expats to claim credits. For example, you can only claim dependent care credit if your caregiver has a TIN, which is impossible with foreign caregivers. Similarly, education credits are only available to eligible foreign institutions, and most foreign institutions are unlisted. 

Where can I find assistance with my US taxes while abroad?

The IRS has an expat section, where you can learn everything you need to comply as a US citizen living abroad. However, it's advisable to seek help from professionals who keep up with US tax laws changes to ensure you stay compliant. 

Filing Taxes Right as a US Citizen Living Abroad

Navigating tax laws as a US citizen living abroad can be confusing, but once you get the fundamentals, it's easy to stay compliant. If you understand what qualifies as taxable income and know the tax credits available for you, you can comfortably manage your expat situation.
