The core of quantitative impact assessment of federal law is the measurement of compliance costs which has to be indicated by the federal government during the process of legislative drafting . According to § 2 NKRG the compliance costs cover the total measurable expenditure of time as well as the cost arising for citizens, the economy and the public administration due to the compliance of a federal norm. The guideline for the measurement and presentation of the compliance costs comprises detailed specifications of compliance costs. However, some costs which may have significant economic impact on affected enterprises are not yet incorporated in the guideline. Therefore, InGFA was assigned by the non-profit foundation for family businesses with a project to identify costs that are not yet considered sufficiently. The final study was presented on the 30th of November 2018 in Berlin.
