Goal and impact

Fees are actually fees for municipal services. Fees are set by the municipal council and are listed in the Fees Ordinance. To levy fees, municipalities must specify base types and fee types. Fees are calculated on a basis. The base type determines where the base for the fee calculation must be found. The fee type determines the calculation to arrive at the fee amount.

Considerations

Because there are many different bases and types of fees, which can also vary from year to year, it is convenient to fill this in once yourself and then use the calculation rules to calculate the correct fees. When employees have to do this manually, the risk of errors is higher and it takes longer to arrive at the correct amount of fees.

Human intervention

Responsible and authorised staff manually approve all calculated fees before they can be invoiced. This is a human interaction that cannot be skipped. This action is also permanently recorded in the application. Initiators (citizens and organisations) have the right to object to the dues imposed or appeal a rejected objection.

Risk management

The risks are minimal, as a staff member is always still assessing the result.

Legal basis

Every municipality adopts the so-called fees ordinance every year. These fee regulations state how the fees are to be calculated and what they are levied on.

Technical design

Fixed rate: In this calculation method, nothing is calculated. Therefore, a base type is also not applicable.

Percentage: In this calculation method, a percentage of the base is calculated. This percentage can be positive (surcharge) or negative (discount).

Scales: This calculation method involves one calculation depending on the scale within which the base falls. This calculation method is applied when there are several calculation rules, of which only one can always be applicable. If the base is between the minimum and maximum, this scale is used. For the calculation, the base is rounded. The factor and base amount can be either positive or negative.

Slices: Under this calculation method, a calculation is performed for each bracket, for that part of the base that falls within the bracket. This calculation method is applied when a graduated calculation is needed. If part of the base is between the minimum and maximum, then that part of the base is used to calculate this tranche. For the calculation, the base is rounded. The factor and base amount can be either positive or negative. After the calculation, the amount is rounded. After rounding, it is checked whether the amount is between the minimum and maximum amount. If the amount is higher than the maximum, then the maximum is used. If the amount is between the minimum and maximum, then the amount is used. If the amount is lower than the minimum, then the minimum is used.
