Coretax Survey Open Until Dec 2, Cash Prizes Up to IDR 2 Million

DDTCNews invites individual taxpayers in Jakarta to complete a short survey about the Coretax system, the Directorate General of Taxation’s online filing platform. The questionnaire is available at and must be submitted by 23:59 WIB on 2 December 2025. Ten selected respondents will share cash prizes totaling IDR 2 million, with tax on the winnings covered by the government.

The survey is relevant because, from 2026, annual income tax returns (Surat Pemberitahuan, SPT) for individuals will be filed exclusively through Coretax. Taxpayers need to activate a Coretax account and obtain an electronic certificate (sertel) that serves as a digital key and signature. These steps unlock all portal features, including the SPT submission.

Responses will be compiled in the December 2025 edition of DDTCNews Focus and may inform the tax authority’s further development of Coretax. Winners will be announced on 3 December 2025, and the editorial decision is final. Participation aids taxpayers in preparing for the upcoming technical requirements.
