(fictional, simplified) Example for a Software Engineer based in Germany [1]:
Gross income: 100.000 EUR / year [2]
-------------------------
TAXES
- Income tax (28.600 EUR)
- "solidarity premium" (2.300 EUR)
- church tax (1.600 € - cumpolsory until you leave the curch)
SOCIAL SECURITY (compulsory)
- unemployed insurance (1.200 EUR)
- pension insurance (7.300 EUR)
- health insurance (4.500 EUR)
- long term care (800 EUR)
-------------------------
Net income: 53.700 EUR
Add to that what is often called gross-gross-income: Hidden from your paycheck is that social security has to be paid by your employer as well (so in this case amounts to 113.080 EUR which makes for a combined rate of 53%) [3]
[1] Hypothetical young graduate from Italy/Spain/France: Unmarried, no children and catholic
[2] 100k is not the typical pay for freshly graduated-from-school devs in Germany, but an attainable income goal after some working years nonetheless
[3] some exemptions in that employer-part, its a bit less than the employee-part
