Indonesia Bolsters Taxpayer Data Security Amidst Expanded Reporting Requirements

Jakarta – Indonesia’s Directorate General of Taxes (DGT) is reinforcing data security measures as new regulations require broader financial data reporting, including credit card transactions. Director General of Taxes Bimo Wijayanto affirmed that the DGT’s data management systems have undergone rigorous testing by multiple state institutions to ensure robust protection of taxpayer information.

Enhanced Security Protocols

“We have undergone a review of personal data protection with Komdigi, as well as with BSSN to review the sovereignty and security of our data and systems,” stated Wijayanto during a media briefing on Thursday, March 5, 2026. Director General of Taxes Bimo Wijayanto emphasized that data protection is a fundamental principle of tax administration.

The DGT’s systems, including the Coretax platform, have been subjected to comprehensive security and data protection reviews. Taxpayer confidentiality is legally protected under Article 34 of Indonesian tax provisions, mandating officials to safeguard data.

Wijayanto highlighted that this principle is integral to the development of DGT technology. The systems also undergo regular security and penetration testing conducted by independent institutions, including the National Cyber and Crypto Agency, the State Intelligence Agency, and the Strategic Intelligence Agency.

Expanded Data Reporting Requirements

These assurances reach following the implementation of Minister of Finance Regulation Number 8 of 2026, signed by Finance Minister Purbaya Yudhi Sadewa. The regulation mandates that government agencies, institutions, associations, and other parties submit relevant tax data to the DGT. Jakarta Globe reported on the appointment of Bimo Wijayanto as Director General of Taxes, replacing Suryo Utomo.

Specifically, banks are now required to report credit card payment transactions made by customers at merchants. This data includes the issuing and acquiring bank identities, merchant details (number and address), transaction values, settlement transaction counts, and canceled transaction totals.

A total of 23 banks are currently obligated to submit these reports, including major institutions such as PT Bank Central Asia Tbk, PT Bank Negara Indonesia Persero Tbk, PT Bank Mandiri Persero Tbk, PT Bank OCBC NISP Tbk, PT Bank Syariah Indonesia Tbk, and PT Bank Rakyat Indonesia Persero Tbk.

Leadership Transition and Focus on Revenue

Bimo Wijayanto was officially appointed as Director General of Taxes on May 20, 2025, by President Prabowo Subianto, succeeding Suryo Utomo. Invest Indonesia notes that this appointment is part of a broader effort to strengthen Indonesia’s fiscal institutions and improve state revenue collection.

Wijayanto’s appointment comes with the task of increasing the tax ratio to gross domestic product and improving the overall accountability of the tax system. Kompas.id highlights the government’s focus on improving the tax system and increasing accountability.
