Tax Residency, Compared.

Tax residency is determined by where you live and your personal circumstances. Most countries use the 183-day rule (spending more than 183 days in a country in a tax year). However, other factors matter: availability of a permanent home, center of vital interests (family, work, economic ties), and habitual residence. For example, Cyprus uses a 60-day rule while Estonia has different rules for e-residents. Always check your specific country's criteria and consult a tax professional to understand your obligations.

Technically yes, but it's complicated. If you meet residency requirements in multiple countries, double tax treaties (DTTs) are used to determine your primary tax residency. Generally, permanent home takes priority, then center of vital interests, then habitual residence, and finally nationality. Once your primary residency is determined under the DTT, you're taxed there on worldwide income (with some exceptions). You may still have reporting obligations in secondary residency countries. Double taxation relief allows foreign tax credits in your home country.

A non-dom (non-domiciled) tax status means you're tax resident in a country but not domiciled there. Under remittance basis taxation, you only pay tax on income you "remit" (bring into) that country. Foreign income, gains, and investments held abroad face reduced or no tax. Countries offering this include Greece, Malta, and Cyprus. However, remittance basis is conditional—usually requiring you to be non-domiciled for tax purposes (often based on domicile of origin) and formal election. Rules are strict and vary significantly by country. You must consult advisors familiar with your home country's rules.

It depends on your visa and country. Some countries (Croatia, Georgia, Estonia, Portugal with D7) offer digital nomad visas that exempt visa holders from local taxation if income is earned abroad. However, you may still owe taxes in your home country or country of citizenship on worldwide income. Countries like the US and many EU nations tax citizens/residents on worldwide income regardless of visa type. Always maintain tax compliance in your home country while leveraging digital nomad visa benefits in your destination. Consult advisors in both countries.

Crypto taxation varies dramatically by country. Italy taxes crypto gains at a flat 33.33% rate. Spain and Portugal treat it as income (progressive rates). Greece's non-dom regime offers 0% tax on unrealized gains not remitted. The US taxes crypto on a per-transaction basis regardless of where you live. Some countries (Georgia, Malta with non-dom) have favorable regimes. Reporting requirements are increasingly strict via FATCA and CRS. Holding crypto in a business structure can change rates significantly. Never assume favorable treatment—research your specific countries' rules and report properly.

Options range from digital banks (Wise, Revolut, N26) offering remote onboarding, multi-currency accounts, and EU IBANs, to traditional banks in your destination country (Banco Best in Portugal, BBVA in Spain). Each has trade-offs: digital banks are convenient but may have limits on what they offer; traditional banks offer full services but require in-person visits or existing residency. For international transfers, Wise offers superior rates. For business banking, Mercury (US) and Wise Business work well. Your choice depends on nationality, residency status, and banking needs. Some countries require tax residency to open bank accounts.
