Foreign National Moved to the U.S. and Didn't Know Worldwide Income Became Reportable

He had moved to Florida mid-year, but his investments and business interests had stayed in Spain. Those records were essential to the answer.

The client's situation

The client had relocated his household to Florida while keeping Spanish bank accounts, investment income and an ownership interest in a Spanish company. He continued receiving income abroad after the move. Because the money remained in Spain and was reported there, he assumed it belonged outside the U.S. tax system.

His travel history included visits before the relocation. We therefore could not simply use the day he signed a Florida lease as his tax residency starting date. This anonymized case illustrates why immigration plans, physical presence and income records must be reviewed together before preparing a new resident's first return.

What went wrong

The misunderstanding was that foreign income becomes reportable only when transferred to an American bank. For a U.S. tax resident, keeping investment proceeds overseas generally does not keep them outside U.S. income tax. Paying Spanish tax also does not replace the U.S. reporting obligation; it may instead support a credit.

The tax or reporting requirement

The substantial presence test generally requires at least 31 days in the current year and 183 weighted days over three years: all current-year days, one-third of the preceding year's days and one-sixth of the second preceding year's days. Exceptions and excluded days must be checked separately.

When residency arises under that test, it generally begins on the first day present in the United States that year, not the day the weighted total reaches 183. Up to 10 days of presence may be disregarded for the starting-date determination if the foreign tax home and closer-connection conditions and required statement are satisfied. Those days still count toward the substantial presence test.

For a taxpayer resident at year-end, a dual-status return generally uses Form 1040 marked as a dual-status return, with a Form 1040-NR statement for the nonresident period. Worldwide income is generally reportable from the residency starting date; nonresident-period income follows the narrower nonresident rules. A first-year election, or an eligible election involving spouses to be treated as full-year residents, may change the result and must be evaluated rather than assumed.

Forms potentially involved:

• Form 1040 — resident-period return
• Form 1040-NR — nonresident-period statement
• Form 1116 — foreign tax credit
• FinCEN Form 114 — FBAR
• Form 8938 — specified foreign financial assets
• Form 5471 — qualifying foreign corporation ownership

The potential IRS exposure

Omitted income can produce additional tax, interest and applicable penalties. Separate information-reporting penalties may apply even when foreign tax credits reduce income tax. An FBAR is generally required when aggregate foreign financial accounts exceed $10,000 at any time during the year, subject to the applicable U.S.-person rules. Form 8938 has separate value thresholds based on filing status and residence; one filing does not replace the other.

How Chirino USA analyzed the situation

Chirino USA reconstructed his arrival and travel dates using passport records and a day-by-day calendar. We checked the current and preceding two years, potential exceptions, and whether any early visit could qualify for the limited 10-day starting-date rule. We then separated income into the resident and nonresident periods using the applicable timing rules.

We reviewed Spanish tax records by income category, rather than treating every Spanish tax payment as a dollar-for-dollar U.S. credit. Form 1116 limitations, sourcing and payment timing matter. We also requested company ownership records to determine whether his interest raised Form 5471 or other international reporting issues.

How we addressed the issue

We prepared the move-year dual-status return using the supported residency date and the appropriate nonresident statement. We calculated available foreign tax credits and reviewed account balances and asset values for FBAR and Form 8938 reporting. Election alternatives were considered with their added worldwide-income consequences, not presented as automatic savings.

The result

The filing approach replaced an incomplete U.S.-income-only return with a documented residency analysis and the related reporting package. The client now has a starting date for worldwide reporting and a list of Spanish records to gather annually. No assumption was made that the IRS had approved the residency position or any credit.

What other taxpayers in similar situations should know

• Review earlier U.S. visits before choosing your move-year residency date.
• Report taxable foreign income even when it stays overseas.
• Check foreign company ownership separately from personal income.
