DGT Issues 454,377 Letters of Inquiry to September

BOGOR, DDTCNews - The Directorate General of Taxes (DGT) has issued 454,377 letters of inquiry (surat permintaan penjelasan atas data dan/atau keterangan/SP2DK in Indonesian) from January through September 2026.

Director General of Taxes Bimo Wijayanto said the letters had been delivered electronically by tax offices, either via taxpayers' email or through coretax.

"Up to 30 September, 454,377 SP2DKs have already been issued," he said at the Ministry of Finance Media Gathering, Thursday (1/10/2026).

Of that total, Bimo elaborated that 384,396 SP2DKs were sent via taxpayers' email, whilst 69,981 SP2DKs were issued through coretax accounts.

According to Bimo, the majority of SP2DKs are still being sent via taxpayers' email because the data or transactions underlying their issuance originate from periods before coretax was implemented in 2025.

"In 2025 there were still 2 systems in use, namely the legacy system and also coretax. For 2026, [tax data management] purely uses coretax," he said.

Bimo explained that 2025 was a transitional period from the former tax administration system, the DGT Information System (SIDJP), to coretax. During that transition, some administrative processes and communications with taxpayers were still conducted via the former channels, including email registered in the DGT system.

Entering 2026, the use of coretax has been strengthened and expanded. As a result, the process of communicating with taxpayers, including when the DGT requests explanations or conveys information, can be carried out through that system.

"In 2026, coretax will be further strengthened and expanded, so that the process of communication and service with taxpayers can be faster, easier and well-documented in each individual taxpayer account," Bimo concluded.

It should be noted that an SP2DK is a letter issued by the head of a tax office (kantor pelayanan pajak/KPP in Indonesian) to request an explanation of data and/or details from a taxpayer in relation to a suspected failure to fulfil tax obligations pursuant to the applicable statutory tax provisions.

The regulations governing taxpayer compliance supervision, including the mechanism for sending SP2DKs to both registered and unregistered taxpayers, are currently set out in Minister of Finance Regulation (MoF Reg.) No. 111/2025. (dik)
