Tax Bill Americans Worked Abroad Texarkana Explained

Every few years, someone comes back. A Texarkana native who spent three years on an oil platform off the coast of Nigeria. A former teacher who did a stint with an international school in South Korea. A military contractor who worked a two-year rotation in Germany and thought the tax part was handled by the government. A missionary who spent nearly a decade in Central America and never once thought about the IRS while they were there.

They come home, settle back into life on the Texas or Arkansas side of the line, and somewhere in the process of getting reestablished — buying a truck, enrolling the kids in school, picking up where things left off — a question surfaces that nobody prepared them for.

Did I file my US taxes while I was gone?

For a lot of people, the honest answer is no.

Why It Happens More Than You’d Think

Texarkana sits at the intersection of two states and a regional economy that sends people abroad more than most mid-size American cities. The oil and gas industry has deep roots here, and energy work takes people to West Africa, the Middle East, Southeast Asia, and offshore platforms in some of the most remote corners of the planet. Military families at nearby bases rotate through assignments across Europe, the Pacific, and the Gulf region. Missionaries and humanitarian workers head out for years at a time with organizations spread across Latin America, Africa, and Asia. Healthcare workers take international contracts. Teachers sign on with overseas school programs.

What most of them have in common when they leave is a reasonable but completely incorrect assumption: that once you’re living and paying taxes somewhere else, America has finished with you for the time being.

It hasn’t. Not even close.

The Rule Nobody Explains at the Airport

The United States is one of only two countries in the world that taxes its citizens on worldwide income regardless of where they live. The other is Eritrea. Every American citizen and Green Card holder is required to file a federal tax return every single year — covering all income from all sources, from anywhere on earth — for as long as they hold their citizenship.

This is called citizenship-based taxation, and it catches people off guard not because they’re trying to avoid anything but because nobody told them. The company that sent them overseas didn’t mention it. The local accountant in whatever country they were living in had no reason to bring it up. And the IRS doesn’t send reminders to foreign addresses.

According to the IRS, Americans abroad must file annual returns and report all worldwide income, applying the same thresholds as someone living in Texarkana and never leaving. The distance doesn’t change the obligation. Neither does the length of time abroad.

The Bill That Built Up While They Were Gone

Here’s where the math gets uncomfortable. Every year that passes without a filing is another year of potential penalties, interest, and unreported foreign account disclosures stacking up quietly.

If an American working abroad has a bank account in the country where they’re posted — and almost everyone does, for the simple practical reason that you need to buy groceries and pay rent — and that account holds more than $10,000 at any point during the year, they’re required to file an FBAR: a Foreign Bank Account Report, submitted separately from the tax return, with its own April 15 deadline.

Missing an FBAR is the part that tends to alarm people most when they discover it. The penalty for a non-willful violation — meaning you genuinely didn’t know you had to file it, not that you were trying to hide something — can be $10,000 per occurrence. Per year. For an account that might have had $12,000 in it just to cover living expenses.

Three years abroad, a single overseas bank account, and a complete lack of awareness that any of this was required: that’s a situation with real dollar consequences sitting behind it, waiting to be discovered.

The Part That Surprises People Most: They Probably Don’t Owe Much

Here’s the piece that tends to shift the conversation considerably. Most Americans who worked abroad — especially in higher-tax countries or on oil and gas contracts with structured compensation packages — don’t actually owe significant US tax once the filing is done correctly. The tools exist specifically to prevent double taxation.

The Foreign Earned Income Exclusion allows qualifying Americans who lived and worked abroad to exclude a substantial chunk of their foreign-earned income from US federal taxation. For the 2025 tax year, that exclusion covers up to $130,000. For someone on a three-year energy contract with a reasonable salary, this exclusion alone can bring the US tax liability for those years to zero or close to it.

The Foreign Tax Credit handles the cases where income tax was already paid to another country, offsetting the US bill with what was already paid abroad.

The actual tax owed, in most returning expat situations, is far smaller than the fear suggests. The problem isn’t the tax. It’s the accumulated unfiled returns and unreported accounts sitting behind those years — and the process of addressing them correctly.

There’s a Way Back That Actually Works

The IRS didn’t design a system that leaves good-faith non-filers permanently trapped. The Streamlined Foreign Offshore Procedures exist specifically for Americans who lived abroad and fell behind on their US filings without willful intent — meaning they didn’t know, rather than didn’t care.

The program covers three years of delinquent federal returns and six years of FBAR filings, typically with penalties significantly reduced or eliminated entirely. For most returning expats in the situation described here — people who simply didn’t know the obligation existed — the non-willful certification is straightforward to document. You were in another country, your life was organized around another financial system, and the IRS requirement for Americans abroad wasn’t something your employer, your local bank, or anyone around you ever mentioned.

The process isn’t instant, and it requires accurate documentation of physical presence, income, and account balances for the relevant years. But it’s a defined, finite process. People complete it every year and come out the other side with a clean compliance record and the weight of the unknown lifted.

The starting point is almost always understanding what the actual numbers look like — which filings are needed, which years are in scope, what the accounts trigger in terms of disclosure, and what the realistic liability is once the exclusions are properly applied. Expat Tax Online works with Americans in exactly this situation, helping returning expats map what they owe, what they don’t, and how to get compliant without the process becoming more complicated than it needs to be.

For Anyone Who Came Home Wondering

If you worked abroad — for any length of time, in any industry, for any organization — and you’re not certain your US taxes were properly filed during that time, the answer to the question is almost always worth finding out sooner rather than later. The situation doesn’t improve with time. The years don’t fall off the record. And the further back it goes, the more documentation needs to be located and organized.

But it’s also almost never as catastrophic as the fear makes it feel in the first moment of realization. Most people who came home from years abroad without filing are dealing with a compliance problem, not a financial crisis. The tools to fix it exist. The process to follow them is documented. And the actual tax liability, once everything is applied correctly, is usually a fraction of what people brace themselves to hear.

The first step is just asking the question.
