Short answer: Greek, Portuguese, Maltese or UAE residence or PR does not automatically make you a tax resident there, nor cancel home-country tax residence. Countries often test days present, permanent home, and centre of family and economic interests. Under the OECD CRS, financial institutions report account information to jurisdictions where you are tax resident. Migration and tax are separate rule sets—assess both before signing investments.
Common myths
| Myth | Reality |
|---|---|
| Golden visa = local tax residence | Residence facts still matter |
| No local return means no CRS | Account-jurisdiction institutions may still exchange data |
| A second passport changes everything | Tax residence follows residence tests more than the passport alone |
| Immigration counsel equals tax advice | Use a qualified tax adviser for tax conclusions |
Questions to ask before planning
How many days will you spend in each country? Where do family and children mainly live? Where are core companies and income generated? Do you intend to establish a local home? Answers affect both immigration renewals and tax-residence risk.
Global Immigrate note
Before Greek/Portuguese/Maltese/Gulf status, obtain a tax memo on post-change residence and filing duties. Do not assume “low-stay migration = zero tax effect.” Cross-border gifts, trusts and corporate structures need earlier design.
