Question about taxes and salary

I guess "Taxes on the revenue" is income tax ?

yes itŽs this sorry

I am told it is taken out by your employer and he is liable to pay the tax office.  Your gross salary is before tax is taken out and net is after or your take home income.

If your self employed then you would have to do it yourself and from what I hear it is made difficult.

thanks for the informative answers. a question: so we dont have to register for tax ourselves im employed so that means my company does it for me? and i dont owe any other tax?

Asked an Italian friend and if it's your first job in Italy you have register with the revenue office here in Italy.  Probably something like a tax file number.  You have to do this,  not your employer.
