In this digital era, the process of reporting the Annual Tax Return (SPT) for Individuals can be done online. However, there are still many Taxpayers who experience difficulties related to the procedure for reporting Annual SPT online. Community service activities in the form of assistance in reporting Individual SPT through e-Filing carried out by students of Nahdlatul Ulama University Sidoarjo as part of the Tax Volunteers held by the Directorate General of Taxes (DJP) located at the West Sidoarjo Pratama Tax Service Office. This activity aims to help reduce the spike in taxpayers who will report annual SPTs and optimize the role of Tax Volunteers in assisting Taxpayers. The method used is assistance and service to Taxpayers. As a result, a number of annual SPTs were successfully reported online. It is hoped that this Tax Volunteer activity will be routine every year with a wider coverage area.

Nowadays, the demands in education to publish scientific papers are increasing. However, some students still do not understand how to publish scientific papers in accredited national journals. This community service activity was carried out to equip final-year students to compile scientific papers that meet national standards.

The presenter first explained the technique of writing scientific papers to the participants, then continued with the practice of submitting articles through the OJS facility. The community service results showed that most participants understood how to compile good and correct scientific papers. In addition, the participants who attended also seemed to understand the steps to submit articles through the OJS facility. Through this training, it is hoped that all final-year students can publish parts of their theses in accredited national journals.
