Strategic and Tactical Guide to Responding to SP2DK in the Modern Tax Supervision Era

In the Indonesian tax ecosystem, which adheres to the self-assessment system, the state places full trust in Taxpayers to calculate, pay, and report their tax obligations independently. However, this trust is balanced by a strict supervision mechanism (compliance risk management) to ensure fairness and certainty in state revenue. The primary instrument used by the Directorate General of Taxes (DGT) to bridge the data held by authorities with Taxpayer reporting is the Request for Explanation on Data and/or Information (SP2DK).

The issuance of an SP2DK often causes anxiety for Taxpayers. However, based on the latest regulations, specifically Minister of Finance Regulation (PMK) Number 111 of 2025, Director General of Taxes Regulation Number PER-18/PJ/2025, and Circular Letter Number SE-05/PJ/2022, SP2DK is essentially a space for dialogue and guidance. SP2DK is neither a tax assessment letter nor a verdict of guilt, but rather an invitation for clarification before the DGT moves to more formal audit actions.

This article will outline comprehensive, strategic, and tactical steps for Taxpayers in responding to SP2DK, from receiving the letter to the final resolution, to mitigate the risk of disputes and administrative sanctions.

Step 1: Identification, Verification, and Careful Reading

The first step upon receiving an SP2DK is to conduct a thorough verification. SP2DK can be delivered through various channels: electronically (DJP Online account), post/expedition, facsimile, or delivered directly via an officer's visit. Taxpayers must ensure the validity of the letter, including checking the letter number, date of issuance, and sender identity.

Read the Delivered SP2DK Carefully

It is crucial for Taxpayers to read the delivered SP2DK carefully. Do not panic. Pay attention to the following details:

• Tax Year: Which year is being questioned? Is the data past the statute of limitations?
• Tax Type: Is it related to Corporate Income Tax, Withholding Tax, or VAT?
• Trigger Data: What specific data is presented by the tax authorities? Is it Concrete Data (such as unreported Tax Invoices or withholding slips) which requires a quick response, or is it complex profiling analysis results?

Step 2: Time Management and Timely Submission

Time management is vital. Based on Article 6 of PMK 111 of 2025, Taxpayers are obliged to provide a response.

If the requested data is complex and takes longer to collect, the regulation provides flexibility. Taxpayers may request an extension for submitting a response for a maximum of 7 (seven) days after the initial period ends. This extension notification must be submitted in writing to the KPP before the initial deadline expires.

Step 3: Data Analysis, Equalization, and Strategy Formulation

After understanding the letter and deadlines, Taxpayers must enter the technical analysis stage. The response to an SP2DK depends on the matching results (reconciliation) between the Taxpayer's internal data and the data presented by the DGT.

Perform Equalization or Other Testing Techniques

To support arguments, Taxpayers are strongly advised to perform equalization or other testing techniques. Equalization is the process of reconciling one type of tax data with other tax data or accounting data to test consistency. For example:

• Turnover Equalization: Compare turnover in the Corporate Income Tax Return with deliveries in the VAT Return. Explain if there are discrepancies.
• Salary Expense Equalization: Compare salary expenses in the profit and loss statement with the Article 21 Income Tax objects.
• Cash and Goods Flow: Test cash flows or goods flows to prove transaction reasonableness.

Compile Explanation with Relevant Data/Evidence

Based on the equalization results, Taxpayers must compile the explanation with relevant data/evidence.

• If the Taxpayer rejects the DGT data: Draft a logical rebuttal letter. Attach authentic evidence such as bank statements, invoices, agreements, or notarial deeds.
• If the Taxpayer accepts the DGT data: The wisest step is to acknowledge it and perform a Tax Return (SPT) Correction according to Article 8 of the KUP Law.

Step 4: Submission Methods

In the era of tax administration digitalization, Taxpayers have flexible options for submitting responses, as regulated in PMK 111 of 2025:

1. Face-to-Face: Visiting the KPP to meet the Account Representative (AR) or when officers conduct a visit.
2. Audio Visual Media: Conducting discussions via online video conference.
3. Written/Electronic: Submitting letters via post, expedition, or provided electronic channels (Coretax).

Step 5: The Discussion Process

If the written explanation is deemed insufficient, or if there are differences of opinion, the DGT may invite the Taxpayer for a Discussion. In this forum:

• The tax officer (AR/Auditor) will confirm the data and equalization results.
• The Taxpayer has the right to defend their arguments with the evidence that has been compiled.
• The results of the discussion will be documented in the Minutes of Request for Explanation (Berita Acara).

Step 6: Follow-up and Legal Certainty

After the clarification process is complete, the Head of KPP will issue a Report on Request for Explanation on Data and/or Information (LHP2DK).

Conclusion

Responding to an SP2DK requires calmness, precision, and a good understanding of the law. With the enactment of PMK 111 of 2025, supervision procedures have become more structured. The key to facing an SP2DK is being cooperative, transparent, and utilizing the right to provide clarification. A proper response turns SP2DK into a tool for compliance improvement (self-correction), rather than a threat.
