If you're an American living abroad, June 15 is an important date on your tax calendar. It marks the end of the IRS's automatic two-month extension to file your U.S. tax return. In 2025, however, June 15 falls on a Sunday, meaning the deadline shifts to Monday, June 16.
While the automatic extension is helpful鈥攅specially for gathering foreign tax documents or waiting on returns from countries with different filing schedules鈥攊t doesn't delay your responsibility to pay any U.S. tax owed. If you owe U.S. tax, interest has been accruing since April 15鈥攃urrently at a rate of 7% per year. Filing now can minimize interest and the penalties you could face if you miss the June 16 extension deadline.
What happens if you miss the June 16 deadline?
Understanding the consequences of missing the deadline is crucial, especially for those who owe taxes. Here's what to expect:
- Interest will continue to accumulate on any unpaid tax balance from April 15 onward.
- The Failure-to-Pay Penalty is 0.5% of the unpaid tax for each month (or part of a month) your payment is overdue, up to a maximum of 25%.
- The Failure-to-File Penalty is 5% of the unpaid tax for each month (or part of a month) your return is late, up to a maximum of 25%. This penalty is in addition to any late payment penalties and will be adjusted to 4.5% per month when both penalties are applied together.听
Still gathering documents?
If you're still waiting on foreign documents or tax returns and can't finalize your U.S. tax return yet, you can still reduce potential penalties and interest. Filing an extension (Form 4868) by June 16 extends your filing deadline until October 15.
Important: This is an extension to file, not to pay. If you expect to owe U.S. tax, making an estimated payment now can help limit interest and late payment penalties. Need help? 听
Beyond the filing deadline: What expats often overlook
Filing a U.S. tax return on time is just the initial step for Americans living abroad. 色花堂s often encounter significant issues by overlooking other reporting requirements or operating under incorrect assumptions about their obligations. Here are some of the most frequent 鈥 and financially damaging 鈥 errors we observe.
鈥淚 don't make enough to file鈥 鈥 A costly misconception
Many expats mistakenly believe their income level exempts them from filing a U.S. tax return. However, filing requirements are nuanced; the income threshold varies by filing status, and U.S. citizens must report their global income regardless of where they live.
色花堂s also often confuse U.S. tax filing thresholds with the Foreign Earned Income Exclusion (FEIE). While the FEIE allows the exclusion of $126,500 of foreign earned income from U.S. taxation, meeting specific qualifications and filing a return to elect the exclusion are mandatory. Your income potentially falling below the filing threshold does not automatically exempt you from the filing requirement.
鈥淚t's just a side gig鈥︹
Even seemingly small amounts of self-employment income can trigger a U.S. filing obligation. If you earned $400 or more from freelancing, consulting, tutoring, or similar work, you are generally required to file a return 鈥 and may owe self-employment tax for Social Security and Medicare. This often surprises digital nomads and part-time freelancers.
Another aspect that can surprise U.S. expats is the potential for ongoing state tax obligations.
Don't forget about state income taxes
Simply leaving the United States doesn't guarantee you're free from state income tax responsibilities. Some states have strict residency rules and may continue to tax individuals who haven't completely cut their residential ties. For instance, if you still hold a driver's license from a particular state, vote in their elections, or maintain financial accounts linked to your previous U.S. address, you might still be considered a resident of that state with continued filing requirements.
FBAR reporting: It's not just about bank accounts!
The Report of Foreign Bank and Financial Accounts (FBAR) is an important compliance obligation separate from your tax return filing. It's required if you have foreign financial accounts and the combined value of all these accounts exceeds $10,000 at any point during the calendar year.
Common FBAR mistakes people make:
-
Thinking each account needs to exceed $10,000: Many people mistakenly believe that if each individual account is under $10,000, there's no need to report. However, it's the combined total of all your foreign accounts that counts toward the $10,000 threshold, even if individual accounts are under $10,000.
-
Thinking it's just for bank accounts: People also assume that FBAR reporting is only for foreign bank accounts, but that's not true. The reporting requirement extends to all foreign financial accounts, including:
-
Foreign bank accounts
-
Brokerage accounts abroad
-
Foreign insurance or annuity plans with cash values
-
Foreign retirement accounts (with some exceptions)
-
Penalties for non-compliance
Failure to file the FBAR can result in severe penalties, starting at $10,000 per violation. This can add up quickly, especially if you miss multiple accounts or years.
Never filed? You're not alone鈥攁nd it's fixable
If you've missed a tax deadline鈥攐r never filed at all鈥攜ou're not alone. Many Americans living abroad are in the same situation, and the good news is, there are options.
Our team has helped thousands of Americans in the same situation. If your failure to file was non-willful, the IRS offers a way to catch up without penalties through the听.听
Even if you don't qualify for that specific program, other solutions may be available. But timing is critical鈥攐nce the IRS contacts you, you may no longer be eligible for certain forms of relief. Acting now increases your chances of resolving things smoothly and avoiding penalties.
This process can be complex and isn't something you want to tackle on your own. We can guide you through every step, including preparing the required disclosure statements to support your case. Catching up could unlock valuable tax benefits.

Filing is the key to accessing those benefits.
Filing tax returns is important - but it's not the only piece of the puzzle. It's just as important to understand the ongoing complexities that can come with living abroad. Cross-border financial situations鈥攍ike being married to a non-U.S. citizen or receiving money from overseas鈥攃an introduce entirely new tax obligations. If you're not aware of them, they can create problems down the line, even if you file your annual tax returns.听
Married to a non-U.S. citizen?
If you're married to a non-U.S. citizen, your tax filing status and obligations can become more complex. If you're married to a non-resident alien, you cannot file as "single." Additionally, you can't file a joint U.S. tax return with a non-U.S. spouse without making an election to file jointly. This is an area where it's important to seek advice from a tax expert. Although filing separately might seem simpler and avoid the complications of a joint filing, it could result in higher tax liability.听
The decision on your filing status is not just about marital status, but about strategically managing your tax situation and anticipating future financial scenarios, as when you're married to a non-U.S. citizen, your financial world becomes globally interconnected, and that can lead to tax consequences in places you might not expect.听
One common area of confusion is gifts and inheritances received from鈥攐r by鈥攁 foreign spouse. These seemingly personal financial events can trigger serious U.S. tax reporting requirements, especially if large sums or foreign assets are involved.
Foreign inheritances and gifts may trigger reporting
If you or your spouse has received a large gift or inheritance (typically over $100,000) from a non-U.S. individual (e.g., a parent), you may have unexpected tax consequences, as well as additional reporting requirements and penalties for noncompliance that can be significant.听There are also differing tax laws that govern when an American receives significant gifts or inherits assets from a nonresident alien spouse.听In the case of two U.S. spouses, gifting of property is unlimited. That is not the case where the other spouse is a non-U.S. spouse. This is something that often gets overlooked, but it's worth consulting a tax expert about, so you're not caught off guard.听
