i don't know where you get ur information. I haven't checked, but last I heard Germany had freedom of religion, and also I know that It is illegal in Germany to produce neo-nazi propaganda and sell it, as well as even making the hail hitler sign in public.
Use of the salute and accompanying phrases has been forbidden by law in Germany and Austria since the end of World War II. Versions of the salute are used by neo-Nazis, who also use the number 88 to stand for "Heil Hitler" (the 8 standing for H, the eighth letter of the alphabet). One version is the so-called KÃ¼hnen salute with extended thumb, index and middle finger, also forbidden in Germany.
so yes thats illegal, and...
Freedom of religion in Germany is guaranteed by article 4 of the Grundgesetz stating that "the freedom of religion, conscience and the freedom of confessing one's religious or philosophical beliefs are inviolable. Uninfringed religious practice is guaranteed."
perhaps you were referring to...
The so-called "church tax" which exists in several European countries is legally not a tax but contributions for the church that are collected by the state at the same time as the state taxes.
In Germany, on the basis of tax regulations passed by the communities and within the limits set by state laws, communities may
* either require the taxation authorities of the state to collect the fees from the members on the basis of the income tax assessment (then, the authorities withhold a collection fee),
* or they may choose to collect the church tax themselves.
In the first case, membership in the community is entered onto a taxation document (Lohnsteuerkarte) which each employer requires from any employee in order to withhold income tax prepayments. If membership in a tax-collecting religious community is entered on the document, the employer has to withhold church tax prepayments from the income of the employee in addition to the prepayments on the annual income tax. In connection with the final annual income tax assessment, the state revenue authorities also finally assess the church tax owed. In case of self-employed persons or other tax payers not employed, state revenue authorities collect prepayments on the church tax together with prepayments on the income tax.
In case of own collection, collecting communities may demand the tax authorities to reveal taxation data of their members in order to be able to calculate the contributions and prepayments owed. In particular, smaller communities (as e.g. the Jewish Community of Berlin) chose to collect taxes by themselves in order to save the collection fee.
Collection of church tax may be used e.g. to found institutions and foundations or to pay ministers.
The church tax is only paid by members of the respective church. People who are not member of a church tax collecting denomination do not have to pay it. Members of a religious community under public law may formally declare to state - not religious - authorities that they wish to leave the community. With such declaration, the obligation to pay church taxes ends. Some communities refuse to administer marriages and burials of (former) members who had declared to leave it.

From what i read it is voluntary to part of the community that is taxed, and isn't decided by the state, it is by the church.
