US Expat Taxes: Guide to Filing in 2025

Are you an American living abroad or considering a move to another country? If so, you’ll need to know how the US taxes expats. 

Tax requirements are complex for Americans and even more so for US citizens living overseas. To help you understand the rules, we put together a simple, straightforward list of the facts. Think of this post as your cheat sheet—the bare bones of what you must know about taxes for expats. 

Let’s get started!

Expat Tax Filing Requirements 

Expats Are Required to File a US Tax Return 

We’ll start with a question our CPAs and tax specialists get asked all the time: 

Do expats have to file US taxes? 

The short answer is yes. Every US citizen must file a US Federal Tax Return as long their income exceeds the minimum filing threshold. 

Your filing status determines your filing threshold, and even if your income doesn’t meet this threshold, you may still want to file—for example, to claim certain tax credits, to receive a refund, or even to have peace of mind. 

Most Expats Do NOT Have to Pay US Taxes 

Now, for some better news: Though the vast majority of expats must file a US tax return, most don’t end up owing US expat taxes. 

Several deductions, exclusions, and credits ensure that Americans living abroad don’t pay tax twice on the same income. However, to qualify for these tax benefits, you must meet certain standards. Keep reading for more details on that. 

You May Need to File a State Tax Return While Living Abroad 

Things can get trickier for expats at the state level. Depending on where you used to live in the US and whether you’re still considered a resident, you may be required to file a State Tax Return, even after moving abroad. 

Some states make it difficult to remove yourself from their tax jurisdiction. Others make it easy. The rules for determining residency vary from one state to the next, and they may impose taxes if any of the following are true:

• You maintain a mailing address there (or use a friend’s or relative’s address) 
• They issued your current driver’s license or ID card  
• You have a spouse or child living there  
• You have a bank account open there  
• Your vehicle is registered there  
• You registered to vote there  
• You own property there  

That said, many states consider you a non-resident once you move away. To learn more about its residency standards, visit your state’s official website. 

One last thing: We’ve talked to numerous expats who didn’t understand the ramifications of owning rental properties or a business. If you earn income from within the state, you must file a state return. 

How to Save on Your Expat Taxes 

Reduce or Eliminate US Taxes with the Foreign Earned Income Exclusion 

Expats can take advantage of a number of tax benefits. One of the most common is the Foreign Earned Income Exclusion (FEIE), which lets you exclude a certain amount of foreign income from US taxation. 

The amount you can exclude increases each year as inflation rises. 

For the 2024 tax year, the maximum exclusion is $126,500 per qualifying individual. If both spouses qualify, they can each claim the full exclusion for a combined maximum of $253,000.

You must pass either the physical presence or bona fide residence test to qualify: 

•  Physical presence test - You were physically present inside a foreign country for 330 days out of any 365-day period. 
•  Bona fide residence test – You lived overseas for at least one calendar year and don’t intend to move back to the US anytime soon. 

You can claim the FEIE by including Form 2555 in your expat tax return and each year thereafter. However, should you decide that you no longer want the exclusion, you cannot claim it for the next five tax years unless you get approval from the IRS. 

The Foreign Tax Credit Is Another Way to Lower Your US Expat Taxes 

Expats can also use the Foreign Tax Credit to reduce or eliminate their US expat taxes. 

It’s a dollar-for-dollar credit based on foreign income taxes you have paid or accrued.  

For example, let’s say you pay $15,000 in foreign income taxes. Later, when you prepare your US tax return, you find that you owe $20,000. The $15,000 Foreign Tax Credit would lower your US tax bill to $5,000. 

And if your foreign income tax bill is higher than what you would have paid in US taxes, you may owe nothing! 

To claim the Foreign Tax Credit, you must file Form 1116. 

Keep in mind the IRS won’t let you “double dip” by using both the FEIE and Foreign Tax Credit for the same income. However, some expats can use one expat tax exemption, exclusion, or credit for some income (say, the FEIE for the first $126,500) and use a different one for their remaining income.  

Not sure if you should use the FEIE or Foreign Tax Credit? Schedule a tax consultation, and one of our tax specialists will help you find the right strategy for your situation. 

Expats Can Reduce Their Taxes Further Through the Foreign Housing Exclusion 

The Foreign Housing Exclusion allows expats to deduct foreign housing-related expenses from their US tax bill. 

You may have the following expenses that qualify: 

• Rent 
• Utilities (but not phone or TV-related expenses) 
• Homeowners Insurance 
• Repairs 
• Parking fees near your home 

However, you can only claim the Foreign Housing Exclusion if you also claim the FEIE and will use Form 2555 for both. 

Expat Parents Can Claim the Child Tax Credit 

Some expats with dependent children who are US citizens or permanent residents have eligibility for the Child Tax Credit.

For the 2024 tax year (returns filed in 2025), the Child Tax Credit (CTC) provides up to $2,000 per qualifying child under age 17. Of this amount, up to $1,700 is refundable through the Additional Child Tax Credit (ACTC), meaning eligible taxpayers can receive this portion as a refund even if they owe no federal income tax.

Eligibility for the full credit depends on your modified adjusted gross income (MAGI). The credit begins to phase out at incomes above $200,000 for single filers and $400,000 for joint filers. Specifically, the credit is reduced by $50 for each $1,000 of income over these thresholds.

To qualify, a child must meet certain criteria, including being under age 17 at the end of the tax year, being your dependent, and having lived with you for more than half the year

You may also be able to deduct childcare costs, using the Child and Dependent Care Credit. To use this credit, you must have earned income—e.g., salaries or wages—and if you excluded all your income with the FEIE, you can’t use this credit.

Tax Treaties Help Prevent Double Taxation for US Expats 

Currently, the US has tax treaties with 69 countries. These treaties reduce double taxation by clarifying which country has the right to tax an expat.  

It’s worth noting that most US tax treaties contain a “saving clause” that protects each country’s right to tax its own citizens—almost as if the treaty didn’t exist. 

US expats in countries with those treaties usually cannot use tax treaty benefits to completely eliminate their US tax bills. However, many tax treaties still provide options for reducing taxes for expats. Consult a tax professional/CPA to figure out what your options are.

Renouncing Citizenship May NOT Help You Avoid US Taxes 

Frustrated with filing requirements or what they pay in taxes, some US citizens consider renouncing citizenship. 

There are a couple of catches to be aware of. Before you can give up US citizenship, you must prove that you have met US tax requirements for at least the last five tax years. Depending on your income and net worth, you may also be subject to an exit tax when you renounce. It usually applies when your net worth exceeds $2 million. 

Some people, especially those who earn income in the US, must continue filing US tax returns after expatriation. They typically pay a flat 30% tax rate on that income.

Filing Taxes as an Expat 

Expats Receive an Automatic Tax Filing Extension Until June 15 

Though expats have the same tax deadline as taxpayers living in the US—typically April 15—that deadline automatically extends to June if you miss it. 

However, to avoid penalties and interest, you still must pay any tax owed by the original deadline.  

Expats can request an additional extension by filing either Form 4868 or Form 2350. The right form depends on your specific situation and needs.

Failing to File Can Result in Severe Penalties 

The vast majority of expats must file a return every year, the same as Americans living in the US. There are no surprises there. 

If you end up owing tax yet fail to file an expat tax return, you’ll most likely incur late fees and penalties for each month your tax return and/or tax payment are late. The longer you wait to fail and the more you owe—that is, the more delinquent you become—the more severe the repercussions.

The IRS has been known to revoke the passports of US citizens who owe taxes and even press criminal charges that can result in jail time. 

The easiest way to avoid getting into trouble? 

Work with an expat tax specialist to file your taxes on time and pay what you owe.

Use the Streamlined Filing Compliance Procedure to Catch up on Taxes 

Years after moving abroad, many expats discover that they do, in fact, have a US filing requirement. Fortunately, the IRS created the Streamlined Filing Compliance Procedures, an amnesty program that lets delinquent expats catch up without facing any penalties. 

To take advantage of this program, here’s what you do: 

• Self-certify that your failure to file was an accident, not a willful refusal  
• File your last three delinquent income tax returns.
• Pay delinquent taxes owed with interest
• File Foreign Bank Account Reports (FBARs) for the last six years 

In most cases, these steps bring you into compliance with IRS regulations, which is a huge relief for expats unaware of their US tax filing obligations.  

You Can Amend a Previous US Tax Return if You Made a Mistake 

Mistakes happen. The IRS gets that, and if you or your tax specialist finds a mistake, you can file an amended return for that tax year using Form 1040-X. 

This form applies to income you failed to report and deductions you didn’t take. 

Additional Reporting Requirements for Expats 

If Your Foreign Account Balances Exceed $10,000, You Must File an FBAR

If the combined balance(s) of all your foreign bank accounts exceed $10,000, you must file FinCEN Form 114, better known as the Foreign Bank Account Report (FBAR). 

This requirement applies even if your account(s) pass that $10,000 threshold for a single day (or minute!) during the year.  

When calculating your FBAR liability, you need to include all foreign bank accounts, including pensions, investments, and accounts that you don’t own but have signature authority over, such as those belonging to a parent or relative. 

The initial deadline for the FBAR is the same as the one for filing tax returns (typically April 15), but you get an automatic extension to October 15 with the FBAR. 

You May Also Need to File a FATCA Report 

Under the Foreign Account Tax Compliance Act (FATCA), US citizens who own foreign assets valued above certain thresholds must file Form 8938, better known as a FATCA report.  

Your filing and residency status determine your value threshold. 

FATCA and FBAR filing requirements are similar but separate. Depending on your situation, you may need to file one or both.

Social Security and Retirement 

You Can Still Receive Social Security Benefits When You Retire Abroad 

If you’re an American expat who is considering retiring abroad, you can still collect your Social Security benefits in most countries. 

Only a small number don’t allow Americans to collect benefits:  

• Cuba 
• North Korea 
• Azerbaijan 
• Belarus 
• Kazakhstan 
• Kyrgyzstan 
• Moldova 
• Tajikistan 
• Turkmenistan 
• Uzbekistan 

However, you can collect back payments once you move to a different country. 

For example, while living in Havana, you can’t receive US Social Security payments. A few years later, after you move to Liberia, Costa Rica, you can collect the payments you missed out on in Cuba. 

Totalization Agreements Determine Which Country You Pay Social Security Taxes To 

The US has totalization agreements with 28 countries. These agreements stipulate which party receives your Social Security tax payments. 

Most of these agreements allow you to use the credits you earn in one country to calculate the benefits you receive in another. This works in your favor. Without such an agreement, you might pay for social security (or its equivalent) in two countries while receiving only one benefit!  

Special Circumstances and Tax Situations 

Buying and Selling Foreign Real Estate Creates Tax Implications 

The tax rules for buying and selling foreign property are similar to the ones for buying and selling property in the US:

• You don’t have to report the purchase of foreign real estate. 
• If you sell your personal residence at a loss, you don’t have to report the sale. 
• If you sell for a profit, you must report it, and you may be subject to a capital gains tax. 

As for the sale of a rental property, you must report it whether it results in a gain or loss. (You must also report any rental income on annual tax returns.) 

Expat Entrepreneurs Are Required to Pay a Self-Employment Tax 

In addition to income taxes, self-employed expats must also pay the self-employment tax while living abroad. This 15.3% tax replaces the Social Security and Medicare taxes in an employer-employee relationship, and the FEIE or the Foreign Tax Credit doesn’t offset it.

 However, other expat tax benefits can still help you lower your US tax bill.

Digital Nomads Must Follow the Same Rules as Other Expats

Digital nomads travel from place to place and work remotely. Many are self-employed, and digital nomad taxes are similar to those of other expats: 

• All digital nomads must file a US Federal Tax Return. 
• Some may need to file a State Tax Return. 
• Self-employed digital nomads must pay self-employment tax. 
• Digital nomads can claim other expat tax benefits if they’re eligible. 

Meanwhile, traveling from place to place without establishing a domicile ​​has unique tax implications that can complicate the expat tax process. A specialized tax professional or CPA at Greenback Expat Tax Services can help you understand and meet your tax obligations.
