JAKARTA, KOMPAS.com - For those accessing the Department of Taxation’s digital tax reporting system (DJP) for the first time, the Coretax DJP interface can be confusing. From logging in, to filling in your profile, to selecting the SPT type, many taxpayers are unsure where to begin. In fact, understanding the initial workflow of Coretax DJP is a crucial step to ensure that the Annual Tax Return (SPT Tahunan) is submitted smoothly and free from technical errors.
