Purbaya's SPT Filing Story: Underpaid Tax by Rp 50 Million

Finance Minister Purbaya Yudhi Sadewa recounted his experience filing his Annual Income Tax Return (SPT PPh) through the new tax system, Coretax.

He admitted that upon filing his SPT for the 2025 tax year, he discovered an underpayment amounting to Rp 50 million.

“Underpayment, around Rp 50 million,” Purbaya stated at the Ministry of Finance in Jakarta on Wednesday (25/3/2026).

Purbaya explained that this situation differs from previous years when he only served as Chairman of LPS, with his income sourced from a single workplace.

“If you work in multiple places, you’re almost certainly going to underpay, unless it’s just one place. When I was at LPS, I never underpaid; it was always exact because my salary was only from LPS. Now, I still have some from LPS and some from here (Ministry of Finance),” he clarified.

He acknowledged that the SPT filing process was assisted by staff from the Directorate General of Taxes (DJP). However, there were initial difficulties in accessing Coretax.

According to him, the development of Coretax is ongoing to make it more accessible to taxpayers.

Improvements will be made both in terms of design and the system itself.

“First, it’s a design flaw. Then there’s the software service or application that connects Coretax with users, to make it faster when using it. So I suspect Coretax here was made complicated, perhaps intentionally to create business opportunities. We’ll fix it later,” Purbaya concluded.
