All Transactions Recorded by Coretax, Purbaya: You Can't Cheat on Tax

Jakarta, CNBC Indonesia — Finance Minister Purbaya Yudhi Sadewa has assured that the core tax administration system, known as Coretax, has become increasingly sophisticated.

According to him, all taxpayer transactions will be fully recorded by Coretax, meaning any accompanying tax obligations will automatically be detected.

“Coretax can already capture where a transaction goes, where the payment is made, everything. So when you fill in your annual tax return, all of that will automatically be visible,” Purbaya said at a press conference at his office in Jakarta on Tuesday (21/7/2026).

Purbaya said the Coretax system was indeed designed in part to prevent tax evasion. He therefore stressed that taxpayers can no longer deceive the government in meeting their tax obligations.

“To me, that is even more frightening — you can no longer fib, you’ll be caught by the tax office, by Coretax, whenever you transact,” he said.

As is widely known, the Coretax system has connected all financial transaction activities of taxpayers, whether at financial institutions or in crypto.

The Director General of Taxes, Bimo Wijayanto, has even officially issued a circular enabling the tax authority to obtain access to financial information from crypto asset service providers, no longer solely from financial institutions such as banks.

This provision is set out in Circular Letter Number SE-9/PJ/2026 concerning the Procedures for Requesting Information and/or Evidence in the Framework of Implementing Access to Financial Information for Tax Purposes.

“The Director General of Taxes is authorised to obtain access to financial information for tax purposes from financial institutions and/or crypto asset service providers reporting under the Crypto Assets Reporting Framework (CARF Reporting Obligated Crypto Asset Service Providers),” the circular, dated Monday (20/7/2026), states.
