ASIATODAY.ID, JAKARTA — Indonesia’s Corruption Eradication Commission (KPK) has uncovered what investigators describe as a structured tax mafia scheme involving a Chinese-linked nickel mining company, PT Wanatiara Persada, following a high-profile sting operation targeting senior tax officials.
The case emerged after the KPK conducted an undercover operation against officials accused of engineering a drastic reduction in the company’s land and building tax obligations, causing an estimated state loss of IDR 59 billion (approximately USD 3.8 million).
Raids Target Tax Offices and Corporate Headquarters
The investigation has ensnared a network of officials at the North Jakarta Medium Tax Office and raised suspicions of broader involvement within Indonesia’s Directorate General of Taxes (DGT) under the Ministry of Finance.
In follow-up raids, KPK investigators searched three strategic locations:
– North Jakarta Medium Tax Office
– The Directorate General of Taxes headquarters on Gatot Subroto Street, South Jakarta
– PT Wanatiara Persada’s head office in North Jakarta
From these locations, investigators seized tax documents, electronic evidence, cash, and precious metals, all believed to be directly linked to bribery and manipulation of the company’s tax liabilities.
KPK spokesperson Budi Prasetyo said the evidence is being analyzed to map the structure of the alleged tax mafia, trace money flows, and identify the roles of each party.
“Investigators are examining all seized evidence to uncover the full construction of the case and the involvement of other parties,” Budi said on Wednesday, January 14, 2026.
Tax Cut by 80 Percent, State Losses Reach IDR 59 Billion
According to Asep Guntur Rahayu, Acting Deputy for Enforcement and Execution at the KPK, PT Wanatiara Persada should have paid approximately IDR 75 billion in land and building tax for the 2023 fiscal year.
However, through alleged manipulation of tax assessments, the payable amount was reduced to just IDR 15.7 billion.
“That represents a reduction of around Rp59.3 billion — nearly 80 percent of the original value. The impact on state revenue was extremely significant,” Asep said.
The KPK stated that the manipulation was carried out through illegal coordination between tax officials, consultants, and company representatives, a pattern investigators describe as a systematic and organized tax mafia practice.
Chinese-Affiliated Nickel Mining Company
PT Wanatiara Persada is a foreign investment company operating in nickel mining, processing, and refining. It is one of Indonesia’s ferronickel producers and has operated a nickel smelter on Obi Island, South Halmahera, North Maluku, since 2019.
Approximately 60 percent of the company’s shares are owned by Jinchuan International, a Chinese mining firm and subsidiary of Jinchuan Group, a state-owned Chinese mining giant with global operations across Asia, Africa, and Latin America.
The company’s smelter uses Rotary Kiln–Electric Furnace (RKEF) technology with four furnaces totaling 4 x 33 MVA, supported by a captive coal-fired power plant (3 x 50 MW), as well as dedicated port facilities, mining roads, and logistics infrastructure.
Past Controversy and the KPK Sting
PT Wanatiara Persada had previously drawn public attention in 2016 during the groundbreaking of its Obi Island smelter project, when it was alleged to have raised the Chinese national flag at the site. The flag was later taken down following intervention by security authorities, as the act was deemed to violate Indonesia’s regulations on state symbols.
In the current tax case, the KPK has named five suspects:
– Dwi Budi, Head of KPP Madya North Jakarta
– Agus Syaifudin, Head of Supervision and Consultation Section
– Askob Bahtiar, Tax Appraisal Team Member
– Abdul Kadim Sahbudin, Tax Consultant
– Edy Yulianto, Staff member of PT Wanatiara Persada
Investigators allege the suspects received IDR 4 billion in bribes to orchestrate the reduction of the company’s tax obligations.
During the January 9–10, 2026 sting operation, the KPK seized assets worth IDR 6.38 billion, including cash in rupiah and Singapore dollars, as well as 1.3 kilograms of precious metals.
KPK Signals Further Arrests Possible
The KPK emphasized that the investigation remains ongoing. Authorities are tracing financial flows and examining the possibility of involvement by higher-ranking tax officials and other actors behind the manipulation of taxes owed by foreign-owned mining companies.
The PT Wanatiara Persada case adds to a growing list of resource-sector tax scandals in Indonesia and underscores long-standing concerns over weak fiscal oversight of foreign mining firms controlling strategic natural resources. (AT Network)
