In Europe, payroll taxes are dominated by social security contributions rather than income tax. Switzerland charges roughly 6.4% AHV/IV/EO and 1.1% ALV on the employee, plus pension fund (BVG) and accident insurance — total employee share around 12–14%. Employers pay roughly the same on top, plus family allowances.
Germany's social wedge is much larger: about 20% from the employee and 20% from the employer, covering pension, health, unemployment and long-term care. France adds 22% on the employee plus 42% employer-side — among the highest in Europe. Italy lands around 9.5% employee and 30% employer.
Payroll taxes finance social insurance and are usually capped at an annual ceiling. Above the ceiling the marginal cost of employment drops sharply — a key consideration in executive compensation and self-employment decisions.
On a EUR 5,000 gross monthly salary in Germany, the employee pays about EUR 1,000 in payroll taxes and the employer about EUR 1,000 more — total labour cost EUR 6,000, employee net before income tax EUR 4,000.
