How to Calculate Your Tax Burden When Moving Abroad

Why Taxes Matter More Than Cost of Living

When comparing destinations, most people focus on rent and groceries. But taxes can make a bigger difference than any other factor. The difference between Portugal's NHR at 20% flat and France's progressive system topping at 45% on a €60,000 salary is over €15,000/year.

Key Concepts

1. Tax Residency

You become a tax resident — usually after spending 183+ days in a country. This triggers worldwide income taxation in most cases.

2. Tax Treaties

Bilateral agreements prevent double taxation. Italy has treaties with 90+ countries. Always check if your origin and destination countries have one.

3. Special Tax Regimes

Many countries offer favorable regimes to attract talent:

Portugal NHR: 20% flat rate (new version post-2024)

Spain Beckham Law: 24% flat rate for 6 years

Italy Impatriati: 70-90% income exemption for 5 years

UAE/Dubai: 0% income tax

Georgia: 0% on foreign-source income

4. Social Contributions

Don't forget social security — these can add 20-40% on top of income tax in countries like France, Germany, and Italy.

Common Mistakes

Ignoring exit taxes — some countries tax unrealized capital gains when you leave

Forgetting municipal taxes — additional 0.5-3% in many European cities

Not planning the transition year — you might pay taxes in both countries

Assuming treaties cover everything — they often have specific exceptions
