Why Your First Year as an Expat Sets the Tone for Your Tax Life

The first year abroad rarely feels permanent. Boxes are still unpacked. The job might be a trial run. Even the lease has an exit clause. Taxes, understandably, slide down the priority list. You tell yourself you’ll sort them out once things feel settled.

The trouble is, tax habits don’t wait for certainty. They form anyway.

And whatever you do or don’t do in that first year tends to echo forward in ways most expats don’t see coming.

The first-year mindset: temporary life, temporary decisions

Talk to enough Americans abroad, and you hear the same story. Year one is about survival. New systems. New payroll. New currency. New everything. Compared to that, U.S. taxes feel abstract, almost optional.

So decisions get postponed. Filing gets skipped. Records get shoved into a folder labeled “later.”

None of that feels reckless at the time. It feels human.

What’s easy to miss is how quickly “just this year” turns into a pattern. Year two follows the template of year one. Year three builds on year two. Eventually, the original assumption—I’ll deal with it later—becomes the foundation everything else rests on.

Why the U.S. tax system surprises expats early on

Part of the problem is structural. The U.S. taxes based on citizenship, not residence. Most countries don’t. So when you move abroad and start paying tax locally, the instinctive conclusion is that the U.S. fades into the background.

Local accountants often reinforce that idea, unintentionally. They’re focused on local compliance, which makes sense. U.S. filing obligations simply aren’t part of their lane.

The first year is where that misunderstanding usually takes root. Not because someone is avoiding anything, but because nothing feels urgent enough to question the assumption.

Early filing choices quietly shape everything that follows

Here’s the part most people don’t hear early enough: your first expat tax return tends to become a reference point.

How income is reported. Whether foreign accounts are disclosed. Which elections are made, or not made. These choices don’t disappear the following year. They carry forward. Software rolls them over. Preparers rely on prior filings. Banks look for consistency.

Fixing a mistake once is manageable. Fixing it after several years of repetition feels heavier, even if the original issue was small.

That’s why first-year clarity matters more than optimization. Clean habits compound. Messy ones do too.

The quiet role of recordkeeping in year one

Year one is also when records are easiest to manage and easiest to lose.

Foreign payslips. Local tax assessments. Exchange rates. Bank statements. At the start, everything is current and accessible. Later, documents scatter. Employers change. Systems update. What was once a quick download turns into a scavenger hunt.

Many expats who fall behind don’t struggle with the rules as much as the reconstruction. The IRS doesn’t ask for perfection, but it does expect consistency. The further you get from year one, the harder that becomes.

When “good enough” advice isn’t actually good enough

Another first-year trap is relying on advice that’s technically correct, just incomplete.

Being “fully compliant” locally doesn’t automatically mean compliant with the IRS. The systems run side by side, not in sequence. One doesn’t cancel out the other.

This isn’t a knock on local advisors. It’s a jurisdiction issue. But if U.S.-specific questions aren’t asked in year one, they usually don’t get asked in year two either. By the time someone realizes the gap, the foundation is already set.

Thinking beyond this year’s return

It helps to zoom out.

Taxes aren’t just about this year’s filing. They affect future moves, banking relationships, mortgage applications, even how simple it feels to move money across borders. A clean tax history rarely announces itself. You only notice it when it’s missing.

The first year is when you decide whether taxes become a background system—or a recurring source of stress.

That choice isn’t about doing everything perfectly. It’s about asking the right questions early, before assumptions harden into habits.

Getting support in your first year living abroad

For many expats, the hardest part of the first year isn’t filing. It’s knowing what actually matters and what can wait.

Expat Tax Online works with Americans living abroad, including those navigating their first year overseas. If you’re unsure how your early decisions might affect your long-term tax picture, speaking with an expat tax specialist can help you build a solid foundation from the start—one that keeps future years quieter, simpler, and far less reactive.

Sometimes the smartest move in year one is making sure year five doesn’t feel harder than it needs to.
