Questions and Answers
Answers to questions about salary structures, work and employment, and social systems across Europe.
Why are income taxes progressive?
Income taxes are progressive because higher portions of income are taxed at higher rates. Instead of applying one rate to all earnings, the system divides income into ranges where each part is treated differently.
In practice, this means that only the higher part of your income is taxed more heavily, not your entire salary.

How progressive taxation works
Income is divided into brackets, and each bracket has its own rate.
- lower income is taxed at lower rates
- higher income is taxed at higher rates
To understand how taxes differ from contributions, see Income taxes vs social contributions (detailed explanation).
What happens to additional income
Each additional amount you earn is partly taxed and partly added to your net income.
This explains why each salary increase may feel smaller than expected.
Effective vs nominal tax rates
Even in a progressive system, the total share you pay is spread across all income brackets.
To understand the difference, see Statutory vs effective tax rate (detailed explanation).
How taxes fit into total deductions
Income tax is only one part of total deductions. Social contributions are also applied.
To see how everything is calculated together, see From salary to net income (detailed explanation).
Differences between systems
Progressive tax structures vary between countries, leading to different outcomes for similar salaries.
