Expat US Tax on Why Americans Are Renouncing

If you’ve ever glanced at the quarterly renunciation list the IRS publishes, the one showing every person who gave up U.S. citizenship, you might have wondered what drives someone to make such a big, irreversible choice. The numbers aren’t massive in the grand scheme of things, but they’re steady enough, year after year, to suggest something deeper than a passing trend. And talking to clients, or even just following the policy debates, you start to see a pattern that feels less like rebellion and more like exhaustion.

It’s not that Americans abroad suddenly stop caring about their country. Most still keep close ties with their family, memories, and the odd craving for Target or Trader Joe’s. What they’re really trying to escape is a tax system that tries to follow them everywhere.

Citizenship-Based Taxation: The Quiet Source of Frustration

The United States is one of only two countries in the world that taxes based on citizenship, not residency. For anyone who has lived abroad for years or even decades, that rule can feel wildly disconnected from their actual life.

Unlike most nations, where tax obligations end when you move away, the U.S. expects you to file a return every year and report your entire worldwide income, even if all your income is earned abroad, even if you haven’t set foot in the States since college.

And the rules aren’t light. Foreign bank accounts, foreign pensions, locally invested mutual funds, foreign businesses, everything has to be reported. A normal-looking retirement plan in UK or Singapore can trigger half a dozen IRS forms.

It’s no wonder some expats start to ask, quietly at first, “Why am I still doing this?”

FATCA: When Foreign Banks Start Saying “No Thanks”

Then there’s FATCA or the Foreign Account Tax Compliance Act. This has been reshaping the financial lives of Americans abroad since 2014. FATCA requires foreign banks to identify U.S. citizens and report their accounts to the U.S. government. The intention was to catch offshore evasion, but the fallout was… messy.

Some banks simply shut the door on American clients because the compliance burden was too high. Others kept them but demanded U.S. tax forms like the W-9, even for basic accounts.

I remember one woman in Denmark who told me she felt almost embarrassed at the bank counter, like presenting a blue passport made her look suspicious. That’s the emotional undertone you rarely see in policy discussions: expats feeling stigmatized or treated like financial risks.

Even though FATCA doesn’t impose new taxes, the way it reshapes foreign banking relationships pushes some people closer to renunciation.

The Weight of Compliance: Small Burdens That Accumulate

Even for expats who can afford accountants, the annual process wears people down. You gather forms, bank statements, pension statements, and employer details, often from multiple countries. You navigate FEIE rules, FTC calculations, and sometimes PFIC reporting if you’ve bought local investment funds (which almost always count as PFICs under U.S. law).

And if you make even a small mistake?
There’s the fear of penalties attached to FBAR or FATCA filings, numbers that can look terrifying on a screen, even if they’re rarely enforced at the maximum.

People don’t renounce the first year; this becomes annoying. But year after year, the pressure builds. For many, the moment comes when they realize they’re spending more emotional energy complying with a country they don’t live in than the one they call home.

Dual Citizens Who Never Asked for the Complication

A surprisingly large number of renunciants are accidental Americans or people born to a U.S. parent or born in the U.S. but raised elsewhere. Some don’t discover their citizenship until adulthood.

Imagine being a 45-year-old living in Germany and suddenly learning you’re supposed to file U.S. taxes every single year, going back decades, even though you’ve never worked in the U.S. That sort of shock pushes people toward renunciation faster than anything else. It feels less like giving something up and more like closing a strange administrative loophole that never fit their life.

The Exit Tax: A Final Roadblock

Of course, renouncing isn’t as simple as mailing in a form. High-income or high-net-worth individuals can face the Exit Tax, a tax on unrealized gains, if they meet certain thresholds. For 2025, that includes the $2 million net-worth test and the average annual tax liability test of $206,000. The exclusion on deemed gains is $890,000 for 2025.

Not everyone triggers the Exit Tax, but the idea of it, such as being taxed on assets you haven’t even sold, adds another emotional layer to the decision.
