<![CDATA[This study is intended to determine the level of effectiveness of the implementation of the letter of reprimand, especially Regional Tax Collection Letters (STPD) and the factors that influence it and to find out the efforts that can be made to maximize tax revenues, especially regional taxes through the issuance of warning letters. This research was conducted indirectly at the Regional Revenue Agency (Bapenda) of Mojokerto Regency, East Java. Based on the results of the study, the active billing action by the Mojokerto Regency Bapenda is still minimal. In addition, the level of effectiveness of tax receipts with warning letters during 2018-2021 did not reach the target so it was classified as ineffective. The issuance of a warning letter has not yet had an impact on Mojokerto Regency's local tax revenue.
