Inp.polri.go.id - Jakarta. The Indonesian government is finalizing plans to implement export duties and a windfall tax on coal and nickel commodities to alleviate the burden of rising subsidies in the state budget and tighten oversight on mineral exports.

"We are discussing this with the Ministry of Energy and Mineral Resources. The goal is to ensure sufficient revenue to cover our increased state subsidies," Minister of Finance Purbaya Yudhi Sadewa said during a media briefing in Jakarta on Monday (4/5/2026), as reported by antaranews.com.

A windfall tax is an additional levy imposed on industries that experience sudden, massive profits due to external market conditions. 

Minister Purbaya highlighted that, currently, coal and nickel are not subject to export duties, which creates significant loopholes for under-invoicing and smuggling. By implementing these duties, the Directorate General of Customs and Excise (DJBC) will gain the authority to inspect shipments before they depart, effectively controlling potential revenue leaks.

While specific tax rates remain under discussion, the Ministry reaffirmed its commitment to the downstream industry, particularly nickel-based battery production. To balance the new taxes, the Ministry is considering incentives for industries that utilize high levels of domestic components in their production processes.
