Two different definitions of “resident”
European Golden Visa statutes typically grant a right to enter, remain, and renew legal residence subject to investment maintenance and minimum-stay rules. U.S. federal income tax, by contrast, hinges on citizenship, the substantial presence test (IRC §7701(b)), and, for non-citizens, treaty tie-breaker elections where available. A client can hold a Portuguese, Spanish, or Greek residence card while remaining fully taxable in the United States on worldwide income if they retain U.S. citizenship or meet substantial presence without a treaty position.
Substantial presence: what triggers questions
Advisors should flag any client who spends meaningful time in both the United States and the host EU country within the same tax year. Days of physical presence in the United States count toward the substantial presence formula unless an exception (e.g., certain student or medical days) applies. Days in the EU country may also matter for that country’s domestic tax-residence tests, which are independent of the Golden Visa marketing label “residency.”
Treaty tie-breakers and Form 8833
Where the United States has an income tax treaty with the host country, Article 4 often contains tie-breaker tests (permanent home, center of vital interests, habitual abode, nationality). Claiming treaty residence is a filing position, not a casual statement in a client meeting. Your client’s CPA or tax attorney should document facts supporting the position and file Form 8833 where required. Promoters who imply that a Golden Visa “moves tax residence” without this analysis create regulatory and litigation tail risk for the advisory stack.
State domicile
Even if federal treaty planning is available, California, New York, and other high-tax states may assert domicile based on voter registration, homestead exemption, family location, and business headquarters. Wealth advisors should pair Golden Visa conversations with state-tax counsel before clients assume they have severed former-state liability.
What to hand to tax counsel
- Calendar of days by country for the prior three years
- Copy of the host-country residence card category and statutory citation
- Summary of investment vehicle (real asset, fund, donation) and lockup
- List of U.S. situs assets, entities, and trust roles
