A 2025 Update to Indonesia's Tax Audit Procedures

Indonesia's tax audit rules will evolve in 2025. With the introduction of Minister of Finance Regulation No. 15 (PMK-15), the government aims to make tax audits faster and more transparent. These changes will affect how businesses are audited and how disputes are resolved.

This guide will explain everything you need to know about the new tax audit procedures and how to navigate them seamlessly for your business.

What changed in 2025?

Effective 14 February 2025, the Ministry of Finance issued PMK-15, replacing earlier audit regulations in PMK‑172, PMK‑256, and PMK‑184. The new rules align with Indonesia's Core Tax system, focusing on efficiency and digital processes to streamline a uniform audit process.

Here are the key highlights of the legal update:

• Effective Scope: The regulation applies to any Tax Audit Notification Letter (SP2) issued on or after 14 February 2025.
• Digital Transition: Audit documents may be digitally signed and submitted electronically, a shift designed to integrate with the Core Tax system.
• Shorter Deadlines: The updated regulation imposes tighter timelines for audit closing and taxpayer responses.

Types of tax audit

Previously, the Directorate General of Taxes (DGT) differentiated compliance checking tax audits into field tax audits, office tax audits, and tax audits for concrete data. However, under PMK-15/2025, Indonesia now classifies tax audits into three types, each with a different focus and duration. This change helps streamline the audit process and improve efficiency.

1. Comprehensive Audit

Covers all tax aspects in detail, including multiple tax types and complete documentation. It applies to complex cases or routine checks. The audit can take up to 5 months.

2. Focused Audit

Targets specific tax items or issues flagged by the tax office. Taxpayers are informed in advance about what will be audited. The process lasts up to 3 months.

3. Specific Audit

It deals with minor or limited issues, like a single transaction. It's the fastest type of audit, completed within one month, and doesn't require preliminary meetings or discussions of findings.

Tax audit new timeline

The 2025 update (PMK‑15/2025) overhauled the timelines for Indonesia's tax audits, improving clarity, speed, and consistency based on the type of audit.

Testing Phase

• Comprehensive Audit: Now up to 5 months, down from the previous 6 months maximum.
• Focused Audit: Maximum of 3 months.
• Specific Audit: Completed within 1 month.
• Extended Audits: The testing phase can be extended to 4 additional months (previously up to 6 months) for group taxpayers or transfer-pricing cases.

Closing & Reporting Phase

Once the audit findings (SPHP) are issued, the tax office has 30 working days to finalize and submit the audit report (LHP). This is shorter than the previous 2-month window.

Taxpayer Response Time

After receiving SPHP, taxpayers have 5 working days to submit a written response. Previously, this window was 7 days, with a possible 3-day extension.

New procedure: Preliminary Audit Findings

Under PMK-15/2025, a new step called the Preliminary Audit Findings Discussion (PAHPS) is now required before finalizing most tax audits in Indonesia.

This formal discussion allows auditors to present early findings and enables taxpayers to clarify issues, respond, or provide additional documents. It increases transparency and helps prevent potential disputes before making the final audit decision.

One-month rule exception for document submission

PMK-15/2025 introduces an essential change to the timeline for submitting documents during a tax audit. Previously, taxpayers had a strict 1-month deadline to provide all requested documents. Under the new rules, this deadline is more flexible, with exceptions as follows:

• The tax office requests documents not listed in the original audit notice (SP2).
• The documents are requested after 1 month has passed.

In these cases, taxpayers must still comply, but the submission timeline is adjusted based on the situation to avoid unfair penalties due to late auditor requests.

Clear separation of tax audit and criminal procedure

Lastly, PMK-15/2025 separates regular tax audits from criminal investigations. If auditors find signs of a tax crime, the audit must stop, and the case is handed over to the Special Tax Investigator. Auditors cannot continue their review once the handover takes place.
