New to America? How U.S. taxes actually work for immigrants
Moving to the United States is an exciting new chapter — and a major financial transition. The tax system here works differently than in most of the world, and the rules you assume from home usually don’t apply. This guide, written by an Enrolled Agent who made this exact journey herself, walks you through tax residency, worldwide income, foreign bank accounts, your first tax return, and the mistakes that cost new immigrants real money.
The short answer: whether you owe U.S. taxes depends on your tax residency status — not your citizenship, your visa alone, or where you were born. Green card holders and anyone who meets the “substantial presence test” (roughly 183 days counted over three years) are generally taxed as U.S. residents on their worldwide income. Nonresidents are generally taxed only on U.S.-source income. And separately from tax, you may have reporting obligations for foreign bank accounts even when no tax is owed.
Your journey into the U.S. tax system
The biggest difference between America and most other countries
Most countries tax primarily the income earned inside their borders. The United States takes a broader approach: once you are a U.S. tax resident, the IRS generally expects you to report your worldwide income — salary from an overseas employer, rent from an apartment you kept in your home country, dividends from a foreign brokerage, profits from a foreign business.
This surprises almost every newcomer. A very common assumption is: “I earned this money outside America, so America doesn’t need to know about it.” For a U.S. tax resident, that assumption is wrong — and acting on it can create penalties that dwarf any tax that was actually due. The good news: reporting income is not the same as being double-taxed on it. Foreign tax credits and treaty provisions usually prevent paying twice on the same income — but only when the return is filed correctly.
Do immigrants have to pay U.S. taxes?
Being an immigrant does not automatically mean you owe U.S. tax. What matters is which category you fall into:
Understanding U.S. tax residency (it’s not the same as immigration status)
Immigration law and tax law use the word “resident” differently. For tax purposes, you are generally a U.S. resident if either of these is true:
- The green card test — you hold lawful permanent resident status at any point in the year.
- The substantial presence test — you were physically present at least 31 days this year, and your weighted three-year total reaches 183 days (all of this year’s days + 1/3 of last year’s + 1/6 of the year before).
Special elections, treaty tie-breakers, and “dual-status” first-year returns can change the picture — which is why two people who land in America on the same day can have completely different filing obligations. IRS Publication 519, the U.S. Tax Guide for Aliens, is the official reference — and its complexity is exactly why professional guidance for the first year is worth it.
Your first tax return in America: what you’ll need
Do I have to report money from my home country?
This is the question we hear most, and the answer depends on what kind of money it is. Money you earned before becoming a U.S. tax resident is generally not taxed by the U.S. — timing matters, which is why the date you become a resident is so important. Transferring your own savings into a U.S. bank account is not a taxable event: moving money is not income. But income that keeps flowing after you become a resident — foreign salary, rental income from property back home, interest and dividends from foreign accounts — generally must go on your U.S. return, even if it never leaves your home country.
Large gifts from family abroad deserve special care: a gift itself is usually not taxable income, but gifts from foreign persons above $100,000 in a year must be disclosed on Form 3520 — a form with penalties measured in percentages of the gift for late filing, not dollars.
Foreign bank accounts: reporting is not taxation
Most immigrants keep financial ties to home — a savings account, an investment account, a retirement fund, a property. U.S. tax residents whose foreign accounts combined exceeded $10,000 at any moment of the year must file an FBAR (FinCEN Form 114), and higher thresholds can trigger Form 8938. Here is the concept that brings our clients the most relief:
Reporting an account does not mean you owe tax on it. Disclosure and taxation are two different systems. Most people who file an FBAR owe nothing on the balances — but the penalty for not disclosing starts around $10,000 per violation even when the mistake was innocent. Report everything; pay only what the law actually requires.
The five most expensive mistakes new immigrants make
Starting a business in America as an immigrant
Many immigrants become entrepreneurs — it is one of the fastest paths to building a life here. You don’t need a green card to own an LLC or corporation. But the structure you choose — sole proprietorship, LLC, S-Corporation — drives your tax bill, your payroll obligations, and even your immigration paperwork. We handle business registration, EIN applications, bookkeeping, and payroll so the foundation is right from day one.
Taxes are the foundation of your American financial life
Your tax returns are not just paperwork — they are the documents that mortgage lenders, immigration officers, and business partners will ask for. Clean, correct filings from year one make it easier to buy a home, sponsor family, apply for citizenship, get business credit, and invest. Your first Form 1040 is your introduction to the American financial system. It’s worth getting right.
Frequently asked questions
Do immigrants have to file U.S. taxes?
If you are a U.S. tax resident (green card or substantial presence) with income above the filing threshold — or with foreign accounts to disclose — yes. Nonresidents file only when they have U.S.-source income.
Do green card holders pay U.S. taxes on foreign income?
Generally yes — green card holders are U.S. tax residents with worldwide reporting obligations, though foreign tax credits usually prevent double taxation.
Is money I transfer from my home country taxable?
The transfer itself is not taxable — it’s your own money moving between your own accounts. What matters is whether the money represents income earned while you were a U.S. resident, and whether the foreign accounts holding it were disclosed.
Do I need to report a foreign bank account if it earns nothing?
If your combined foreign balances topped $10,000 at any point in the year — yes, on the FBAR, even if the account earned zero interest. Disclosure is required regardless of income.
What if I haven’t filed since I moved here?
Don’t panic, and don’t stay silent. The IRS has streamlined procedures for people who genuinely didn’t know their obligations, and catching up voluntarily is dramatically cheaper than being found first. This is exactly what an Enrolled Agent handles.
Can I get help in Russian or Ukrainian?
Yes — Omega Tax Group provides full service in English, Russian, and Ukrainian. See our Russian-speaking accountant page.
