SP2DK and Tax Audit

Navigating Tax Compliance: Understanding SP2DK and Audit Processes in the Coretax Era

Under Indonesia's self-assessment system, the Directorate General of Taxes (DGT) has significantly modernized its oversight through the Core Tax Administration System (Coretax). This technology renders tax supervision faster, more integrated, and transparent. For Taxpayers, distinguishing between a "request for clarification" and an "official audit" is vital to mitigating heavy administrative penalties.

1. Legal Framework & Digital Transformation

Tax supervision and audits are now governed by the KUP Law (as amended by Law No. 6/2023) and specific new regulations:

• PMK No. 111/2025: Digital procedures for SP2DK and compliance monitoring.
• PMK No. 15/2025: Integrated tax audit procedures within the Coretax system.
• PER-18/PJ/2025: Specific follow-up protocols for "concrete data" findings.

2. SP2DK: The Data-Driven "Yellow Light" (PMK 111/2025)

An SP2DK (Request for Explanation on Data and/or Information) is issued when Coretax’s Early Warning System detects discrepancies between your filings and third-party data.

• Omnichannel Delivery: Notifications are automatically sent to your Taxpayer Portal, email, or via post.
• The 14-Day Clock: You must respond within 14 calendar days from the date the letter is sent to the Portal or received.
• Response Mechanism: Explanations and PDF supporting documents are uploaded directly through the Portal. The outcome is legally recorded in an Execution Minutes (BAP2DK).
• The Risk of Silence: Failure to respond triggers the system to escalate the case to an Official Tax Audit or a Preliminary Evidence Investigation (criminal tax fraud).

3. New Tax Audit Structure

Per PMK 15/2025, audit types are now more streamlined to ensure time efficiency:

Document Rule: Requested documents must be submitted within 1 month. Late submissions will be disregarded and cannot be used as evidence during subsequent Objection or Appeal processes.

4. Risk Simulation: Concrete Data Scenario

Imagine Coretax detects an unreported input tax invoice:

• Notification: DGT issues an SP2DK to your Taxpayer Portal.
• Negligence: You ignore it for more than 14 days.
• Escalation: The system escalates the case to a Specific Audit based on concrete data.
• Rapid Audit: The auditor works within a very short window (e.g., 10 days). Because you failed to provide evidence during the supervision stage, the auditor may reject your late arguments.
• Final Outcome: A Tax Underpayment Assessment Letter (SKPKB) is issued with penalties. Your bargaining position is weakened as the initial momentum for proof has been lost.
