I'm not sure what the exact translation would be into English, but it is effectively your tax statement from the tax authorities.

It's difficult to understand from your question exactly what you're asking for, as you seem to be confusing a tax statement with the levels of income tax you pay.

From this question, and some of the others you've asked on this site, my only advice is for you to consider going to see an accountant to see if you can get yourself set up correctly. You need to avoid getting into difficulties with the tax and social security authorities.

You will have to pay tax in fonction of your income.
The benefits you get from social security depend on your status.

Might be best to visit your local tax office and ask for information directly from them.
