💡 The Foreign Earned Income Exclusion (FEIE) is often the go-to move for U.S. expats—but is it always the smartest one?

FEIE: A Tax Tool with a Catch 🪝

If you’re a U.S. citizen living and working abroad, you’ve probably heard of the Foreign Earned Income Exclusion (FEIE). On the surface, it sounds like a tax win: you can exclude up to $132,900 of your foreign salary or self-employment income in 2026 from U.S. tax. Add in the housing exclusion or deduction, and the number gets even bigger.

But here’s the thing: while the FEIE can wipe out your U.S. tax bill, it can also quietly block you from claiming other valuable benefits — credits, deductions, even retirement contributions.

Let’s walk through what many expats don’t realize they’re giving up.

IRA and Roth IRA Contributions? 🚫 Not If You Exclude Everything

To contribute to a Traditional or Roth IRA, you must have taxable earned income. If you exclude all of your foreign-earned income under the FEIE, guess what? You have no U.S. taxable compensation. That means no IRA contributions are allowed, even if you earned $ 100,000+ overseas. For expats trying to save for retirement, that’s a big deal. This can be especially frustrating for expats who feel limited in their foreign investment options due to the punitive PFIC tax regime for investors in foreign mutual funds and ETFs.

👶 Bye-Bye to the Child Tax Credit

Have kids? The Child Tax Credit, even the refundable part that can result in an actual check from the IRS, isn’t available if you claim the Foreign Earned Income Exclusion. Even if your income is modest and your kids meet all the criteria, the IRS sees that FEIE checkbox and says, “Sorry, no refund for you.” 

I have begun working with many expats who have lived abroad and claimed the FEIE for many years, and then they start a family, and realize that they won’t be able to receive the Child Tax Credit like many of their American friends, if they continue with the exclusion. It’s a relatively easy fix to revoke the FEIE and begin using the Foreign Tax Credit… along with the Child Tax Credit (if it suits their unique circumstances, of course)!

👨‍👩‍👧‍👦 Dependent Care Credits? Also Tied to Earned Income

The Child and Dependent Care Credit gives you a tax credit for a percentage of what you pay for childcare or care for disabled dependents while you (and your spouse, if married) work or look for work. Similar to the Child Tax Credit, the Child and Dependent Care Credit requires earned income. If your income is fully excluded under the FEIE, you may not qualify… even if you paid for daycare or summer camp.

---

💸 No Earned Income Credit

The Earned Income Tax Credit (EITC) is also off the table if you use the FEIE, even if your remaining taxable income is low. It’s an automatic disqualifier.  (Side note: most expats don’t qualify for this anyway because the EITC requires that you’ve lived in the U.S. for at least 6 months of the year).

🌍 Paying Foreign Taxes Without U.S. Relief

Here’s a big one: if you’re paying high taxes abroad (say, in the U.K. or much of Europe), you can’t claim a U.S. foreign tax credit on income you’ve excluded. So you might pay 30–45% in foreign tax and get no U.S. tax relief or carryover credit for that. That may not feel like a big deal if you’re using the FEIE and paying no U.S. taxes with your filing each year.  But, if you expect to pay U.S. tax in future years (after moving, selling property, or losing the FEIE), you’re missing the chance to build FTC carryovers now that could offset future tax bills.

🇮🇹 Example from Italy

Let’s say you’re a U.S. citizen living and working in Milan, earning the equivalent of $100,000 USD, and paying roughly 45% in Italian income taxes. You also have two young children, both U.S. citizens with Social Security numbers, which would typically qualify you for the Child Tax Credit.

If you fully exclude your earned income using the FEIE, you may owe nothing to the IRS…but you’ll also lose out on two major benefits:

1. You cannot claim a U.S. foreign tax credit for the $45,000+ you paid to the Italian tax authorities. That’s a huge tax cost with no U.S. offset or carryover.
   
2. You also lose eligibility for the refundable portion of the Child Tax Credit, even though your children otherwise qualify. In some cases, that could mean missing out on up to $3,400 or more in credits the IRS would otherwise refund to you.

So even though it might feel like a win to avoid U.S. tax entirely, you’ve just given up valuable credits and received no U.S. benefit for the high foreign taxes you’ve paid.

P.S. Those lost foreign tax credits could have helped you down the road. For example, you may take a distribution from your Italian pension that’s only partially taxed (or tax-free) in Italy. Well, for U.S. tax purposes, it’s considered fully taxable. Without carried-forward foreign tax credits, you may owe a large U.S. tax bill later with no relief in sight.

🧠 Planning Smarter: FEIE vs. FTC

Sometimes, not claiming the FEIE is the better move — especially if you live in a high-tax country and can claim the foreign tax credit (FTC) instead. The FTC allows you to use the taxes you already paid abroad to offset your U.S. tax. It can also help preserve eligibility for IRA contributions and other helpful tax credits.

✨ Final Thoughts: Don’t Let Simplicity Fool You

The FEIE is a great tool, but it’s not one-size-fits-all. Choosing it without understanding the trade-offs can mean missing out on money you’re entitled to, now or in the future.

Before filing, take a beat. Look at the whole picture – where you live, how much you earn, what your foreign taxes look like, and what credits or deductions you’re eligible for. And if you’re not sure what’s best? That’s what we’re here for. 😉
