Membership and personal conviction are different questions.
A religious community needs a legal basis to levy tax. Article 140 of the Basic Law incorporates provisions of the Weimar Constitution. Religious communities with public-law corporation status may levy taxes under the relevant state rules. That power does not mean every religious community uses it.
The membership information helps establish whether such tax obligations apply. It does not ask how strongly someone believes or how frequently they attend worship. The connection to learn is legally relevant membership and possible church tax.
The other three answers
The tax connection matters, rather than a general statement about religion.
it is important for statistics in Germany.
Church tax is the reason sought here. Statistics required by law can also justify collecting information, but that is not the specific tax-return answer.
you have to pay more taxes if you don't belong to a church.
This reverses the connection. Church tax generally depends on membership of a tax-levying community; not belonging to a church is not subject to a general penalty tax.
the church is responsible for the tax return.
A religious community’s taxing power does not make it responsible for an individual’s entire income-tax return. The question asks why membership matters.
The general rule does not determine an individual tax case.
The actual calculation depends on applicable rules and personal circumstances. A church-tax rate usually applies to the relevant tax, not simply the entire gross salary. No amount or individual payment obligation is determined here.
Article 136 of the Weimar Constitution, also incorporated into the Basic Law, generally protects against being required to disclose religious conviction. Authorities may ask about affiliation where rights or obligations depend on it or a legally mandated statistical survey requires it.

Remember the link to income and wage tax without inferring an obligation for everyone with religious beliefs.
