Taxpayers Urged to Avoid Filing SPT Near Deadline as Coretax System May Become Congested

The Directorate General of Taxes (DJP) is still awaiting taxpayers who have not yet filed their Annual Income Tax Return for PPh 21 via Coretax. The filing deadline is 31 March 2026 for individual taxpayers (OP) and 30 April 2026 for corporate taxpayers. For individuals, there are fewer than a week of days left for filing. The issue is that many file close to the deadline, which actually disadvantages the taxpayers themselves. This is because the Coretax system may become congested near the end of March 2026, making online filing slow even with high bandwidth. “So that Eid truly returns to its purity, just report your taxes promptly,” explained Bimo, as quoted from Kompas.com on Monday (16/3/2026). In addition, there are fines looming for taxpayers who file late, in accordance with the General Provisions and Tax Procedures Law (UU KUP) Article 7(1). From this, it is hoped that taxpayers will report their SPT as soon as possible. The steps are summarised below, quoted from pajak.go.id. The filing steps for SPT are not complete yet. Next is to create an authorisation code or electronic certificate. There you have it, the steps to file SPT on Coretax. Hopefully useful.
