The 2025 Expat Tax Guide: Don’t File Until You Read This

Tax Time

Moving abroad changes a lot—your morning routine, your grocery list, your ability to find a decent bagel.

What doesn’t change?

Your tax obligations to the US. The IRS still expects a tax return, whether you’re filing from a Parisian apartment or a beachside cabana in Belize.

I’ve spent years helping Americans abroad navigate the complexities of filing from overseas.

Small missteps—like missing a deadline or failing to report a foreign account—can turn into expensive headaches.

There’s a proposed residence-based taxation (RBT) bill that could offer tax relief for expats in the future.

But if you’re filing for 2025, here’s what you need to know before you start.

The April 15 Tax Deadline Still Applies—Even If You’re Abroad

Many expats assume that living overseas means more time to pay your tax bill.

While US taxpayers abroad get an automatic two-month extension to file until June 16, 2025 (since June 15 falls on a Sunday), any taxes owed are still due by April 15. If you miss that payment, interest starts accruing immediately.

Before filing, it’s essential to review what’s required based on where you live, how much you earn, and what assets you hold abroad. Bright!Tax’s 2025 Expat Tax Season Checklist breaks down the key steps, from reporting foreign income to checking FBAR (Foreign Bank Account Report) requirements.

Have a Foreign Bank Account? The IRS Wants to Know

If you had more than $10,000 total across foreign bank accounts at any point during the year, you must file an FBAR (Foreign Bank Account Report) by October 15, 2025.

Additionally, under FATCA (Foreign Account Tax Compliance Act), if your foreign financial assets exceed $200,000 (for single filers), you may also need to file Form 8938. Failing to report these accounts can lead to steep penalties—even if no taxes are owed.

The IRS Is Getting More Aggressive About Expat Compliance

Gone are the days when expats could assume the IRS wouldn’t track them down.

With increasing international banking transparency and FATCA agreements, more countries are sharing financial data with the US government.

If you’re living abroad, the best approach is simple: know your obligations, take advantage of the exclusions available to you, and file on time. A little preparation now can save you a lot of trouble later.
