This paper attempts to provide an answer to the following research question: how did the budgetary transparency develop in the city of Bjelovar during the term of office of the current local authorities in the period between 2017 and 2020?

The collected data has been coded in accordance with the rules of qualitative data analysis. In its conclusion, this paper states that the development of budgetary transparency in the city of Bjelovar can be labeled, despite some defects, as an example of an aspect of good governance.
