ABSTRACT
This research explain about implication of the change of assume and discharge mechanism into cost recovery mechanism post Government Regulation No. 79 Year 2010 in the imposition of land and building tax for the upstream oil and gas contractor during the exploration phase reviewed by the ease of administration principle which then used as the evaluation ground to the policy. This research used quantitative descriptive approach and qualitative data collection method. This research concludes that the change of assume and discharge mechanism into cost recovery mechanism for the imposition of land and building tax for upstream oil and gas exploration activity is unsuitable with the ease of administration principle and unfulfilled the 6 dimensions of policy evaluation. An advice to resolve this issue is to re apply the assume and discharge mechanism for oil and gas contractor during the exploration phase.
