In an effort to maximise taxpayer compliance, the Directorate General of Taxes is transforming and reforming the tax system, one of which is the e-filing program for individual taxpayer reporting. Electronic reporting in the e-filing system is also carried out by taxpayers registered at KPP Pratama Surabaya Wonocolo. This study aims to analyse the effectiveness of the E-filing Program in order to increase compliance with the reporting of Annual Individual Income Tax Return with a discussion regarding the fulfilment of effectiveness measurement indicators based on the effectiveness theory proposed by Budiani (2007). This research method is descriptive research with a qualitative approach, and data collection is done by interview, observation, and documentation techniques. The results obtained were then collected, reduced, presented, and conclusions were drawn. The results of this study indicate that the effectiveness of the e-filing programme at KPP Pratama Surabaya Wonocolo has generally met the criteria for measuring effectiveness according to Budiani, but there are still things that have not been optimally done. Apart from that, there are several supporting and inhibiting factors in the implementation of the e-filing programme at KPP Pratama Surabaya Wonocolo.
