Purbaya's Candid Revelation on Why Coretax is Often Slow: There's Mischief Involved!

Finance Minister Purbaya Yudhi Sadewa has stated that there are mischievous parties behind the frequent technical issues plaguing the Coretax system. Purbaya mentioned that some of his subordinates dared to use a prohibited vendor to re-engage with the Coretax system.

Previously, Purbaya claimed that the Coretax system was secure with no technical problems. However, he recently discovered that Coretax is again experiencing disruptions in the form of endless processing loops.

“Suddenly, there were reports again that the Coretax was spinning in circles, even though it had disappeared before. It turns out that in our organisation, there are naughty elements; someone contracted with a vendor that we had already stopped because of its slow service, and they sneaked it back in,” said Purbaya, quoted from detikFinance on Friday (27/3/2026).

Purbaya noted that to date, none of his subordinates have admitted to the deed.

“Now they won’t admit who brought it back in; I’ll investigate again who reintroduced that vendor, and we will take action,” Purbaya asserted firmly.

He then highlighted the odd design of Coretax. The former LPS chairman assessed that certain parties had made the Coretax design non-ideal to profit from the resulting problems.

“The Coretax design is a bit strange. It should have been directly interfaced with the public from the start to make it easy. But it turned out to be complicated, with an intermediary interface application in the middle. This is being sold to large companies; I only just found out,” Purbaya explained.

However, he emphasised that a comprehensive overhaul cannot be done in the near term because the system is still operational. In the meantime, Purbaya has directed his team to focus on securing the system and removing existing obstacles, before further improvements are made over the next year or so.

“I’ll sort it out. But not now, because it’s already running; over the next year, we’ll fix it. We’ll secure all of Coretax first, eliminate the bottlenecks, and then I’ll clean up that deliberately created interface space,” Purbaya added.

On another note, Purbaya mentioned that the submission of Notification Letters (SPT) will still be extended until the end of April, as the number of taxpayers reporting has not yet reached the target.
