Reply #7: Is there a step missing?

[ProSense]

The OP states:

So how does it work? Let me give first my personal example. Each month I get about 4200 euros on my bank account from my employer. But my employer
pays 9500 for my salary. The difference, that is 5300, goes almost entirely to la Sécu (that's the social contribution). About half of that serves for Health insurance.

On the 4200 I get, I still have to pay the tax on the revenue (about 450 in my case) and local taxes (about 450 as well - I live in a city where local taxes are very high).

Is the 465 euros, you mentioned equivalent to the 5300 or the 900 in the second graph?

If it's equivalent to the 5300, how much additional is revenue and local taxes?
