About error of system processing about use charges such as nursery schools

Usage fees for daycare centers are calculated based on the municipal tax income percent, and for those who have moved in from outside the city, tax information is provided from other municipalities through information cooperation using the My Number system. Calculated.
This time, in the usage fee of nursery schools from FY2018 to FY2021, there was an error in the system processing of tax information, and for 11 people, the usage fee of nursery schools etc. was calculated less than the original amount It turned out that the claim was made. In the future, we will ask you to pay the difference from the usage fee, etc. that should be paid. We apologize for any inconvenience this may cause.
