The Corruption Eradication Commission (KPK) has launched a significant crackdown on alleged tax fraud, naming Mulyono, the Head of the Medium Tax Service Office (KPP Madya) in Banjarmasin, as a suspect in a high-profile bribery case. The illicit funds he purportedly received were allegedly channeled, in part, towards a down payment for a personal residence, underscoring the severity of the corruption charges.
This intricate case involves three primary suspects. Alongside Mulyono, the KPK has also implicated:
- Dian Jaya Demega, a Tax Official and member of the KPP Madya Banjarmasin’s Examining Team; and
- Venasius Jenarus Genggor alias Venzo, the Finance Manager of PT Buana Karya Bhakti (BKB).
Asep Guntur Rahayu, the Acting Deputy for Enforcement and Execution at the KPK, elaborated on the case, which centers on the fraudulent processing of Value Added Tax (VAT) restitution for PT BKB for the 2024 tax year. Investigations suggest an alleged scheme of complicity and illicit dealings that ultimately led to the approval of a substantial tax refund totaling IDR 48.3 billion.
In exchange for facilitating this restitution, Mulyono and Dian Jaya allegedly received bribes, euphemistically referred to as ‘appreciation money.’ Mulyono is accused of taking IDR 800 million, while Dian Jaya received IDR 200 million. Furthermore, Venasius reportedly demanded a share of IDR 500 million, with an additional IDR 20 million from Dian Jaya.
“Of the IDR 800 million received, Mulyono subsequently utilized IDR 300 million for a house down payment, with the remaining IDR 500 million still held by his trusted associate,” Asep revealed during a press conference at the KPK’s Red and White Building in South Jakarta on Thursday (February 5th).
The chronology of events detailed by Asep began in 2024 when PT BKB submitted an application for VAT restitution to KPP Madya Banjarmasin, citing an overpayment status. A subsequent audit by the KPP team identified an overpayment of IDR 49.47 billion, subject to a fiscal correction of IDR 1.14 billion, bringing the approved restitution amount to IDR 48.3 billion.
By November 2025, Mulyono met with representatives from PT BKB, specifically Finance Manager Venzo and President Director Imam Satoto Yudiono. In a follow-up meeting, Mulyono explicitly informed Venzo that the restitution application could be approved, subtly hinting at the requirement for “appreciation money.”
This illicit demand was allegedly agreed upon by PT BKB, with a total value of IDR 1.5 billion, which included a “sharing money” component for Venzo. Consequently, KPP Madya Banjarmasin issued the Overpayment Tax Assessment Letter (SKPLB) and the Tax Overpayment Refund Decree (SKPKPP) in December 2025, leading to the disbursement of the IDR 48.3 billion restitution funds into PT BKB’s account on January 22, 2026.
Following the successful disbursement, Dian Jaya reportedly demanded his share of the “appreciation money.” To facilitate these payments, PT BKB allegedly issued fictitious invoices. Asep further disclosed that the IDR 800 million intended for Mulyono was handed over by Venzo in a cardboard box within the parking area of a Banjarmasin hotel.
“MLY then took the money and entrusted it to his confidant, at one of his franchise establishments,” Asep clarified. During the sting operation, the KPK also uncovered information suggesting that Mulyono purportedly held positions as a commissioner in several companies, indicating a broader network of financial interests.
For their actions, Mulyono and Dian Jaya have been charged under Article 12 a and Article 12 b of Law Number 31 of 1999, as well as Article 606 paragraph (2) of Law Number 1 of 2026. Meanwhile, Venzo faces charges under Article 605 and Article 606 paragraph (1) of Law Number 1 of 2026. As of now, none of the three suspects have issued a statement regarding the allegations.

The DJP further stated its commitment to full cooperation throughout the KPK’s legal process. “The Directorate General of Taxes will be highly cooperative and will follow up in accordance with applicable regulations,” Rosmauli asserted. She added, “For the specific details of the incident and further explanations, we defer entirely to the KPK.”
