Received a U.S. Green Card? What Happens to Your Foreign Income, Companies and Investments?

This anonymized case shows why green card foreign income tax questions require an international review, including whether tax residency actually began before the card was received.

The client's situation: a green card and assets abroad

The client had moved from Mexico and retained a stake in a family corporation, an interest in a foreign partnership, rental property, mutual funds and several bank accounts. Her foreign advisers prepared local returns, but nobody had mapped those assets to U.S. classifications and reporting requirements.

Immigration status is distinct from tax residency. A temporary visa does not by itself determine the tax answer. The green card test and substantial presence test establish domestic-law residency, subject to applicable exceptions and treaty rules. Questions about immigration status itself belong with an immigration attorney.

What went wrong

The client believed foreign income mattered only when transferred to the United States. She also assumed her local company's tax return covered every obligation associated with its profits. U.S. tax residents generally report worldwide income regardless of remittance, and some foreign company rules can require current income inclusions without dividends.

Another concern was timing. Receiving a green card does not erase earlier substantial presence or restart tax residency. We needed to establish the original residency date before deciding whether the current year alone, or earlier returns too, required attention.

The tax or reporting requirement

Under the green card test, residency generally starts on the first day physically present in the United States as a lawful permanent resident. Substantial presence can produce an earlier date: generally at least 31 current-year days and 183 weighted days over three years, counting all current-year days, one-third of prior-year days and one-sixth of second-prior-year days. Starting-date and dual-status rules depend on the facts.

Green card tax residency generally continues until permanent resident status is formally abandoned or revoked, or otherwise ends under applicable law. Moving abroad or allowing the physical card to expire does not by itself end the tax obligation. Long-term residents may face expatriation rules when status ends; that requires a separate review.

Foreign corporations may require Form 5471; ownership, control and attribution determine filing categories and potential CFC, Subpart F and GILTI or successor tested-income consequences for the year. Foreign partnerships may require Form 8865. Foreign mutual funds may be PFICs requiring Form 8621. Local labels do not conclusively establish U.S. entity classification.

FBAR generally applies when foreign financial accounts exceed $10,000 in aggregate at any time. Form 8938 is separate: a single filer living in the United States generally uses thresholds over $50,000 at year-end or $75,000 anytime. Other filing statuses and residence circumstances have different thresholds. Directly owned foreign real estate generally is not itself an FBAR or Form 8938 asset, although related accounts and entity interests may be reportable.

Foreign tax credits may reduce double taxation, subject to source, timing and category limits. A treaty tie-breaker position may be relevant in a genuine dual-residence situation, generally involving Form 8833 and Form 1040-NR. For green card holders, such a position can carry immigration implications and potential long-term-resident expatriation consequences; coordinate with an immigration attorney and international tax adviser before taking it.

Forms potentially involved:

• Form 1040, or applicable dual-status filings, for worldwide income during residency.
• Forms 5471 and 8865 for qualifying foreign corporation and partnership interests.
• Form 8621 for applicable PFIC holdings; Form 1116 for eligible foreign tax credits.
• FinCEN Form 114 (FBAR) and Form 8938 under their separate rules.
• Forms 1040-NR and 8833 only where an applicable, reviewed treaty position supports them.

The potential IRS exposure

Omitted foreign income may create tax, interest and penalties. Some Form 5471 and Form 8938 failures can carry initial $10,000 penalties, with additional consequences depending on the facts. FBAR exposure follows separate rules, and filing an income tax return does not substitute for it. We did not assume any particular penalty applied before reviewing the records.

How Chirino USA analyzed the situation

Chirino USA reviewed travel history, the permanent-residence effective date, prior U.S. returns and foreign returns. We obtained ownership percentages, related-party interests, financial statements, partnership agreements, fund documents and maximum account balances. That let us distinguish ordinary investment income from entity-level information reporting and possible undistributed-income inclusions.

We also reconciled foreign taxes by income category and year. A foreign payment is not automatically a usable U.S. credit. Historical costs and exchange rates were necessary because becoming a resident generally does not reset investment basis to market value.

How we addressed the issue

We prepared an asset-by-asset filing matrix, identified records needed from foreign advisers and reviewed any earlier-year gaps separately before selecting a correction approach. For the current cycle, the recommendations connected worldwide-income reporting, potential company and partnership forms, PFIC review and the independent account reports.

We established a calendar for foreign financial statements, estimated taxes and reporting deadlines. Florida has no individual state income tax, but that does not remove federal international obligations; connections to other states need their own review.

The result

The client received a coordinated compliance plan explaining which assets needed income reporting, which needed information returns and which required more classification work. The strategy replaced the assumption that a green card was only an immigration event with a documented annual review process. It did not depend on moving all foreign assets to the United States.

What other green card holders should know

• Confirm whether tax residency predates the green card.
• Inventory indirect ownership, not just accounts in your own name.
• Keep foreign tax and historical basis records alongside annual statements.
• Review tax consequences before selling funds, restructuring companies or ending permanent residence.
