In the Indonesian tax ecosystem, which adheres to a self-assessment system, full trust is placed in Taxpayers to calculate, pay, and report their own tax obligations. However, to ensure fairness and legal certainty, the tax authority—in this case, the Directorate General of Taxes (DGT)—has the authority to test and supervise this compliance. The most vital instrument currently bridging the functions of guidance and law enforcement in tax administration is the Request for Explanation on Data and/or Information (SP2DK).
This article will comprehensively elaborate on the definition, legal basis, working mechanisms, and implications of SP2DK for Taxpayers, referring to the latest regulations including Minister of Finance Regulation Number 111 of 2025 and related rules on Concrete Data.
The issuance of SP2DK is not an arbitrary action but an execution of the legal mandate to conduct guidance and supervision. The highest foundation of this mechanism is the Law on General Provisions and Tax Procedures (UU KUP), which grants the Director General of Taxes the authority to supervise compliance.
Operationally, these supervision procedures have evolved. Previously, technical guidelines were detailed in Circular Letter of the Director General of Taxes Number SE-05/PJ/2022. However, to provide stronger legal certainty, the government has issued Minister of Finance Regulation (PMK) Number 111 of 2025 concerning Supervision of Taxpayer Compliance.
This regulation, effective from January 1, 2026, elevates supervision provisions from the circular level to the ministerial regulation level, affirming the legality of interactions between tax officers and Taxpayers. Additionally, specific regulations regarding "Concrete Data" are outlined in Director General of Taxes Regulation Number PER-18/PJ/2025 and Circular Letter Number SE-9/PJ/2023.
SP2DK is a letter issued by the Head of the Tax Service Office (KPP) to a Taxpayer in the context of requesting an explanation regarding data and/or information. The issuance of this letter is a manifestation of Material Compliance Research.
The primary goal of issuing an SP2DK is not merely to punish, but to provide an opportunity for Taxpayers to conduct clarification (self-correction). If Taxpayers realize there is an error based on the data presented by the DGT, they can correct their Tax Returns (SPT) voluntarily before an audit action is taken.
The supervision process begins with data analysis. The DGT possesses information systems that process various data, both internal and external (ILAP). Tax officers, specifically Account Representatives (AR), perform validation and analysis on this data. If indications of non-compliance are found, the Head of KPP has the authority to issue an SP2DK.
Specifically, there is a priority category known as Concrete Data (PER-18/PJ/2025), which includes:
If the concrete data has a statute of limitations for assessment of more than 12 months, supervision is conducted via SP2DK. However, if the statute of limitations is less than 90 days, the DGT may directly propose an Audit (Pemeriksaan) without going through SP2DK.
Once an SP2DK is issued, it is delivered through various channels: DJP Online, email, facsimile, or delivered directly via a visit. Based on PMK 111 of 2025, Taxpayers are given 14 (fourteen) days to provide an explanation. Taxpayers can respond by:
Extensions may be granted for a maximum of 7 (seven) days after the initial period ends.
The DGT may invite Taxpayers for a Discussion. The results must be documented in the Minutes of Request for Explanation (Berita Acara). These minutes serve as a legal document recording the agreement or disagreement.
Account Representatives (AR) are also authorized to conduct Visits to validate data or perform geotagging of business locations. During these visits, officers must show their identification and assignment letters.
The final results are documented in the LHP2DK. The following are the follow-up scenarios:
SP2DK is a vital mechanism that balances the state's authority with the Taxpayer's right to defend themselves. With PMK 111 of 2025, this process becomes increasingly structured and legally binding. Receiving an SP2DK is not a verdict of guilt, but a dialogue space to ensure tax compliance is met according to actual conditions.
