How to Upload PPh 21 Withholding Evidence in Coretax: Taxpayers Urged to File SPT Promptly

The Directorate General of Taxes (DJP) has mandated that the 2026 Annual Tax Notification (SPT) filing must be conducted through Coretax. If taxpayers prefer not to file online, they may visit the nearest Tax Office (KPP). The online filing is designed to simplify and accelerate the process, thereby achieving tax revenue targets promptly. The Coretax system facilitates this by allowing operators to monitor in real-time the number of taxpayers who have submitted their Annual SPT. “It’s fixed to be extended until the end of April, a one-month extension,” said Finance Minister Purbaya Yudhi Sadewa, quoted from Kompas.com on Wednesday (25/3/2026). So, how to file the Annual SPT in Coretax? Before that, after activating a Coretax account, taxpayers need to check the BPA1 withholding evidence. Here’s how, quoted from pajak.go.id. - Log in to coretaxdjp.pajak.go.id - After logging in, select the My Portal module then click on the My Documents menu - Then search for the document titled Withholding Evidence for Income Tax Article 21 A1 (BPA1) - Scroll the table to the right and click the Download button to download the withholding evidence - If the document does not appear, click the refresh button. After downloading, taxpayers can fill in and upload the BPA1 withholding evidence. Here’s how. - Open the Tax Notification (SPT) menu then click on the Annual SPT concept - Then go to the SPT Attachments section, select List of Withholding or Collection Evidence for Income Tax - In that section, taxpayers can add data by selecting the Add Data option or Upload Document, then fill in the information according to the withholding evidence they have - After the data is entered and the document uploaded, users can save the data before proceeding with the SPT filing process. However, if the withholding evidence has already been reported by the employer and recorded in the DJP system, the data will usually appear automatically during SPT filling. Thus, taxpayers do not need to upload the document again. - Visit the page https://coretaxdjp.pajak.go.id/ - In Coretax DJP, access the Tax Notification (SPT) menu > Tax Notification (SPT) > Create SPT Concept - Select Personal Income Tax (PPh) then click the Continue button - Select Annual SPT and enter the period and tax year (for example, January - December 2025).
