Self-employed workers face a unique tax burden: unlike employees who split social contributions with their employer, the self-employed often pay both halves of the social contribution — effectively doubling the visible rate. In the USA, this is the self-employment (SE) tax of 15.3%. In Germany, freelancers pay pension, health, unemployment, and care contributions entirely themselves. Understanding the combined income tax + social contribution rate is essential for self-employed workers comparing countries.
This guide covers the total effective tax rate for self-employed individuals at $50,000, $100,000, and $150,000 income levels across major economies, including both income tax and mandatory social contributions.

| Romania (micro-co) | 1–3% on revenue | ~15–17% | ~16–20% |
| Bulgaria | 10% flat | ~30% (pension + health) | ~40% |
| Hungary | 15% flat | 18.5% employee social | ~33% |
| Singapore (EP holder) | 0–22% progressive | 0% (no CPF) | 7–15% effective |
| Portugal (IFICI) | 20% flat | ~15% | ~35% |
| UK | 20–45% | 6–8% NIC | 26–53% |
| Germany | 14–45% | ~35–40% (if paying all) | 49–85% |
