Key Insights & Analysis

Important considerations beyond the headline tax rates

Tax Trends to Watch

Global tax policy is shifting. Key developments:

  • OECD Global Minimum Tax: 15% minimum corporate tax affecting multinationals and potentially high earners
  • Digital Nomad Visas: 40+ countries now offer specific visas, but tax treatment varies widely
  • Exit Taxes: More countries implementing departure taxes (France, Netherlands, USA)
  • Remote Work Rules: Many countries tightening rules around remote workers establishing tax residency

Hidden Costs to Consider

The full picture includes more than income tax:

  • Social Security: Can add 7-20% on top of income tax (Germany: ~20%, France: ~17%)
  • VAT/Sales Tax: Europe averages 20% VAT; USA has no federal sales tax
  • Property Taxes: USA property taxes can exceed $10,000/year; UK council tax is much lower
  • Healthcare: "Free" healthcare isn't free - it's funded through taxes or social contributions
  • Cost of Living: A 0% tax rate in UAE means little if rent is $40,000/year

Tax Treaty Considerations

International moves involve complex treaty rules:

  • Double Taxation: Most countries have treaties to prevent being taxed twice
  • Tie-Breaker Rules: When you're resident in two places, treaties determine which country taxes you
  • US Citizens: USA taxes citizens worldwide regardless of residence (unique globally)
  • 183-Day Rule: Common trigger for tax residency, but not the only factor

Quality of Life Tradeoff

Low taxes don't always mean better life:

  • High-tax Nordics: Consistently rank highest for quality of life, happiness, and healthcare
  • Zero-tax UAE: No income tax, but limited worker rights, extreme heat, and cultural restrictions
  • Swiss Balance: Moderate taxes with exceptional infrastructure, safety, and services
  • True Cost: Factor in what you'd spend privately for services covered by taxes elsewhere
