Children from the age of one have a legal right to a childcare place. In order to prevent the claiming of a childcare place from failing for financial reasons, the State of Bavaria subsidizes all three kindergarten years. No application is required for this, the subsidy is paid directly to the relevant institutions. In addition, the Bavarian nursery allowance has been available since 1 January 2020. This relieves parents of up to €100 per month from their child's first birthday onwards in the form of parental contributions for attendance at an institution that is subsidized under the Bavarian Child Education and Care Act (BayKiBiG). The nursery allowance is only paid to parents whose income does not exceed a certain limit. An application is required for the grant.

You can apply for the Bavarian nursery allowance at the Bavarian Center for Families and Social Affairs.
For families with very low income there is also the possibility that the local youth welfare office completely covers the parents' contributions for attending day care facilities.
