In the Indonesian tax ecosystem, which adheres to the self-assessment principle, the state places full trust in Taxpayers to calculate, pay, and report their own taxes. However, this trust is balanced by a strict supervision mechanism (compliance risk management) to ensure compliance. The primary instrument in this supervision dialogue is the Request for Explanation on Data and/or Information (SP2DK). The issuance of an SP2DK is not the end of the tax process, but the beginning of a clarification cycle that has various branches of resolution, ranging from voluntary tax return (SPT) correction to the risk of an audit.
This article will narratively dissect all alternatives for SP2DK resolution, the mechanism for SPT correction post-SP2DK, and the accompanying legal consequences based on the latest regulations, including Minister of Finance Regulation (PMK) Number 111 of 2025 and provisions regarding Concrete Data.
SP2DK is issued when the Head of the Tax Service Office (KPP) discovers indications of non-compliance or discrepancies between the data held by the Directorate General of Taxes (DGT) and the Taxpayer's report. This letter is a manifestation of Material Compliance Research activities.
It is crucial to understand that SP2DK is a space for dialogue. Taxpayers are given 14 (fourteen) days from the date the letter is sent or delivered to provide a response. If necessary, this period can be extended. The Taxpayer's response becomes the main branching point determining the future resolution of the case.
The most expected scenario in the issuance of SP2DK is the Taxpayer's awareness to perform self-correction. If the Taxpayer agrees with the data and analysis presented in the SP2DK, the resolution step is to perform an SPT Correction (Pembetulan SPT).
Based on Article 8 of the KUP Law, Taxpayers may voluntarily correct the Tax Return that has been submitted by submitting a written statement, provided that the Director General of Taxes has not yet conducted an Audit action. This is the "golden window" for Taxpayers. As long as the Audit Instruction Letter (SP2) has not been issued, the Taxpayer is safe from criminal sanctions and is only subject to administrative sanctions.
If the Taxpayer admits the mistake, corrects the SPT, and pays the resulting underpaid tax, the case is considered closed:
In the context of PMK 111 of 2025, if the Taxpayer agrees with the data but has not yet made a payment or correction during the discussion, this will be documented in the Minutes of Meeting, and the Taxpayer must commit to resolving it by the agreed deadline.
Often, the data held by the DGT needs contextual confirmation. Taxpayers have the full right to refute the data in the SP2DK if they feel the data is incorrect.
Taxpayers can provide written explanations or face-to-face meetings (including via video conference). This process is called Discussion (Pembahasan). In this forum, Taxpayers submit withholding slips, bank statements, or other supporting documents to refute the income assumptions alleged by the tax authorities.
There is special treatment for Concrete Data. Based on PER-18/PJ/2025, concrete data is data that only requires simple testing, such as unreported Tax Invoices or Withholding Slips issued by counterparties but not reported in the SPT.
The resolution of SP2DK regarding Concrete Data has time urgency:
This is the resolution path most to be avoided. If during the SP2DK process indications of tax crimes are found—for example, the use of fictitious tax invoices or intentional failure to deposit collected taxes—the administrative supervision process (SP2DK) is stopped and diverted to a Preliminary Evidence Audit (Bukper).
However, even at this Bukper stage, the KUP Law (Article 8 paragraph 3) still provides an ultimum remedium opportunity. Taxpayers can disclose the untruth of their actions by paying the tax due plus a 100% fine before the investigation begins.
If the SP2DK is not responded to and the Taxpayer cannot be found, or the data shows that the Taxpayer's status is inappropriate (e.g., a Taxable Person who does not report but has large transactions), the DGT can resolve it through Ex Officio Data Changes. This can be in the form of Ex Officio confirmation of Taxable Person (PKP) status or revocation of tax facilities.
The issuance of SP2DK offers various resolution alternatives that depend heavily on the Taxpayer's response. The key lies in transparent communication and time management. Post-SP2DK SPT correction is a legal mechanism provided by the state to avoid heavier sanctions due to audits. By understanding the flow from self-correction, discussion, to the risk of concrete data audits, Taxpayers can navigate this supervision process wisely, ensuring compliance, and minimizing the risk of future disputes.
