Moving to the U.S. from Abroad on a Visa? What “Being an Inpat” Means for Your Taxes

Most of the conversation around cross-border taxes focuses on Americans moving abroad. But there’s an equally complicated — and often more urgent — situation on the other side of that equation: foreign nationals moving to the United States for work. If you’re relocating here on a visa, either on your own or bringing your family along, you’ve likely already discovered that the U.S. tax system has its own learning curve, and it starts almost the moment you land.

This is often referred to as being an inpat (short for inbound expatriate) — someone leaving their home country to work in the U.S. And while the terminology may be new to you, the tax implications are very real, and they start well before your first U.S. paycheck.

The First Question: Are You a U.S. Tax Resident?

Before anything else can be figured out, you need to know whether the IRS considers you a U.S. tax resident for the year — because residents and nonresidents are taxed very differently. This isn’t determined by your visa type alone; it comes down to two tests:

The Green Card Test. If you’ve been issued a green card, you’re generally treated as a U.S. tax resident, regardless of how much time you’ve actually spent in the country.

The Substantial Presence Test. Even without a green card, you can be considered a U.S. tax resident based on the number of days you’re physically present in the U.S., calculated using a formula that weighs the current year more heavily than the prior two years combined. Cross a certain threshold, and you’re a resident for tax purposes — which means the IRS taxes your worldwide income, not just what you earn in the U.S.

This distinction matters enormously. A nonresident is generally taxed only on U.S.-source income. A resident is taxed on everything, everywhere — foreign investment income, foreign rental property, foreign business interests, all of it.

The Year You Arrive Is Often the Most Complicated One

Here’s something that catches a lot of inpats off guard: the year you move to the U.S. is frequently a dual-status year — part of the year as a nonresident, part as a resident — depending on exactly when you arrive and what your prior visa history looks like. Dual-status returns are among the more complex individual filings in the entire U.S. tax system, with their own rules about which income gets reported under which status, and specific restrictions on deductions and credits that don’t apply to a standard return.

Timing your move, when you have any flexibility to do so, can genuinely affect your tax outcome for that first year. This is exactly the kind of detail worth discussing before your move date is finalized, not after.

Avoiding Double Taxation

If you’re still earning income in your home country during the transition — a final paycheck, deferred compensation, investment income, or a business interest you haven’t fully wound down — the risk of being taxed on the same income by both your home country and the U.S. is real. Two tools generally help address this:

• Tax treaties. The U.S. has income tax treaties with many countries, and these treaties often include specific provisions for individuals in transition — sometimes reducing withholding, sometimes providing relief for certain types of income during a moving year.
• The Foreign Tax Credit. If income ends up taxed in both places, a credit for foreign taxes already paid can offset your U.S. liability on that same income, dollar for dollar in many cases, rather than paying twice.

Neither of these applies automatically. They require an accurate understanding of your specific facts, correctly claimed on your return — and missing them means paying more than you legally owe.

Bringing Your Family Adds Another Layer

If you’re relocating with a spouse and children, a few additional questions come up regularly:

Filing status. Depending on your residency status and your spouse’s, you may have a choice between filing separately or jointly — including, in some cases, a special election to treat a nonresident spouse as a resident for tax purposes. This decision can meaningfully affect your overall tax outcome and is worth running the numbers on rather than defaulting to whatever feels simplest.

Dependents and credits. Children moving with you may qualify for certain U.S. tax benefits, but eligibility often depends on Social Security numbers, residency status, and timing within the year — details that aren’t always intuitive for a family experiencing the U.S. system for the first time.

A spouse who isn’t working (yet). Visa restrictions sometimes limit a spouse’s ability to work in the U.S. immediately, which can affect household income planning and filing decisions in that first year.

State taxes. Federal tax rules get most of the attention, but the state you relocate to has its own tax system entirely, and the rules for establishing state residency — and what that means for your state tax bill — are separate from the federal residency tests above.

Social Security and Totalization Agreements

If you’re continuing to contribute to a home-country pension or social security-equivalent system, or if your U.S. employer is required to withhold U.S. Social Security tax on your wages, it’s worth checking whether your home country has a totalization agreement with the United States. These agreements are designed specifically to prevent inpats (and expats) from paying into two countries’ social security systems simultaneously for the same work, and from losing credit toward benefits in either system.

Why This Deserves Specialized Guidance

The U.S. tax code wasn’t written with a single, simple story in mind — it has entire sections dedicated to exactly this kind of cross-border transition, and getting the details right requires more than a general understanding of “how U.S. taxes work.” Between residency testing, dual-status filing rules, treaty benefits, foreign tax credits, and family-specific decisions, there are multiple points where a well-intentioned DIY approach can leave money on the table or create complications that follow you into future years.

Working with a CPA who specializes in this exact transition — rather than general U.S. tax preparation — means someone is actively looking for the treaty provisions, credits, and timing decisions that apply specifically to your situation, rather than you discovering them after the fact.

A Few Questions Inpats Ask Often

“Do I need to file U.S. taxes even in the year I arrive, if I only worked a few months?” Generally, yes — even a partial year of U.S.-source income or residency typically creates a filing requirement, though the specifics depend on your dual-status situation for that year.

“I’m still being paid partly from my home country. Does that get taxed here too?” It depends on the source and type of income, your residency status, and any applicable treaty — worth answering with your specific facts rather than a general rule.

“My employer’s tax equalization program says they’ll handle this — do I still need my own accountant?” Employer equalization programs are often designed to simplify payroll withholding and protect the company’s interests, not necessarily to optimize your personal outcome. An independent review is frequently worthwhile even with equalization support in place.

“What happens to my taxes in my home country once I’m a U.S. resident?” That depends on your home country’s own rules, separate from the U.S. side — worth confirming rather than assuming obligations simply stop.

“How early should I start thinking about this?” As early as possible — ideally before your move date is finalized, since some of the most valuable planning opportunities depend on timing decisions made before you arrive, not after.

The Bottom Line

Moving to the U.S. on a visa — whether solo or with your family — comes with real, sometimes urgent tax questions from the moment you arrive. Understanding your residency status, avoiding double taxation on income still connected to your home country, and making the right decisions for your family’s specific situation all matter far more than most people realize until they’re already in the middle of it. Getting ahead of these questions before your move, or as early as possible after, tends to make the entire process smoother and less costly.
