In the first case, membership in the religious community is stored in a database at the Federal Tax Office which employers receive excerpts of for the purpose of withholding tax on paid income. If an employee's data indicate membership in a tax-collecting religious community, the employer must withhold church tax prepayments from their income in addition to other tax prepayments. In connection with the final annual income tax assessment, the state revenue authorities also finally assess the church tax owed. In the case of self-employed persons or of unemployed taxpayers, state revenue authorities collect prepayments on the church tax together with prepayments on the income tax.
