Face It or Flee It: How to Handle a Tax Audit in Indonesia

The envelope from the local tax office, or Kantor Pelayanan Pajak, tends to land on a finance director’s desk at the worst possible time. The instinctive reaction is rarely “how do I explain this.” It is almost always “how do I avoid this.” That impulse is understandable. It is also, in most cases, exactly the wrong strategy.

The avoidance reflex produces a particular pattern that Indonesian tax practitioners see repeatedly: companies that are actually in an overpayment position choose to file their annual returns as nil or underpayment, not because that reflects their actual financial position, but to stay off the audit radar. The logic is easy to understand. A return filed as overpayment triggers an automatic Tax Audit, while a nil or underpayment return may go unexamined entirely, or at the earliest face scrutiny five years down the line. In the short term, this feels safe. In the long term, it creates a larger problem: legitimate refund rights that are never claimed, a tax position that no longer reflects reality, and documentation that becomes increasingly difficult to defend when the tax audit eventually arrives.

The more useful frame is simpler: a tax audit is a process with defined rules, a fixed timeline, and specific points at which a well-prepared company can either protect its position or lose it. Understanding that process, and building the documentation habits that support it, is what separates companies that move through tax audit with minimal disruption from those that spend six months in reactive damage control.

What Actually Triggers a Tax Audit in Indonesia

An audit is not a random event. The Directorate General of Taxes, or DJP, initiates examinations based on specific criteria under Article 4 of Minister of Finance Regulation Number 15 of 2025 (PMK 15/2025), the current regulatory framework for all tax audit procedures in Indonesia, effective from 14 February 2025. Knowing which conditions apply to your company is the first step to genuine risk management rather than unfocused anxiety.

The most common triggers are:

• Filing an overpayment return and requesting a tax refund (restitusi). This is the most predictable trigger of all. When a company claims overpayment  tax back from the state under Article 17B of the General Taxation Law (UU KUP), DJP is legally required to examine that claim before paying it out. Submitting a tax refund request is, in effect, an invitation to be tax audited. The right response is not to avoid claiming legitimate refunds, it is to enter the process with documentation that can withstand scrutiny. DJP’s own 2024 Annual Report recorded refund discrepancy, the value of refund claims not upheld after examination, at IDR 16.46 trillion, down 27.93% from IDR 22.84 trillion the year before but still a substantial figure that reflects how frequently underprepared tax refund claims are filed. It is worth noting that as of 1 May 2026,.
• An unresolved SP2DK. A Tax Clarification Request Letter (Surat Permintaan Penjelasan atas Data dan/atau Keterangan) is not a formal audit. It is a data-matching inquiry, an opportunity for the company to explain an identified discrepancy before the matter escalates. When SP2DK responses are inadequate, late, or ignored, the case is escalated to a formal examination under SP2. Most tax audits that arise from SP2DK could have been resolved at the SP2DK stage with a complete, timely response.
• Third-party data matching. DJP does not need to guess. Through Coretax, banking data, e-Faktur records, and cross-referencing with counterparty filings, the authority already holds a version of a company’s transaction history before any SPT is submitted. When the company’s reported figures diverge materially from those external data points, a specific-purpose examination is the natural consequence. This is precisely why strategies built around underreporting revenue are not merely non-compliant. They are analytically fragile in an era when the data asymmetry between DJP and taxpayers has narrowed significantly.
• Other structural conditions. Article 4 of PMK 15/2025 also triggers tax audits when a company reports consecutive annual losses, undergoes a merger, changes its fiscal year, or revalues its fixed assets. These are legitimate corporate events, but each one increases tax audit probability and therefore increases the importance of having clean supporting documentation ready.

The Tax Audit Process Under PMK 15/2025: A Roadmap

PMK 15/2025, which took effect on 14 February 2025, replaced three prior regulations: PMK 17/2013, PMK 256/2014, and Article 105 of PMK 18/2021. The consolidation brought structural clarity and, for taxpayers, a tighter timeline at several key stages. Understanding the sequence is not optional preparation. It determines how much room a company actually has to respond at each point.

Stage One: The Tax Audit Order (SP2)

The Surat Perintah Pemeriksaan (SP2) is an internal DJP document that formally assigns an audit team. It is the official start of the examination. Following the SP2, the company receives a Surat Pemberitahuan Pemeriksaan, which functions as the external notification and starts the examination clock running.

Stage Two: The Testing Period

PMK 15/2025 introduced three examination categories, each with a different testing period running from the notification date to the issuance of the preliminary findings letter:

• Comprehensive audit: examines all items in the tax return in full depth. Maximum testing period: five months. This applies to most SPT Tahunan PPh Badan, SPT Masa PPN, and property tax examinations.
• Focused audit: examines one or several specific items in depth. The company is notified in writing which items are in scope. Maximum testing period: three months.
• Specific audit: examines one or a small number of items through a simplified procedure. Maximum testing period: one month. Verification of Article 21 PPh withholding on salaries is a common example.

For transfer pricing and group taxpayer cases, the testing period for comprehensive and focused audits can be extended by up to four months.

Stage Three: Preliminary Findings Discussion

This is a procedural innovation introduced by PMK 15/2025 and one of the most practically useful stages for a well-prepared taxpayer. Before any findings are formally communicated, the examination team is required to discuss preliminary conclusions with the company. This is not a negotiation in the colloquial sense, but it is a structured opportunity to provide context, clarify misclassifications, and correct data errors before they are locked into an official document.

Stage Four: The SPHP and the Five-Day Deadline

The Surat Pemberitahuan Hasil Pemeriksaan is the formal statement of findings. Under Article 18(2) of PMK 15/2025, the company has exactly five working days to submit a written response to the SPHP. This is shorter than the seven working days available under the previous PMK 17/2013 framework, and there is no extension available. Five days is not generous time to prepare a formal SPHP response. A company that is not ready within that five-working-day deadline will have wasted its opportunity to contest the findings.

Stage Five: The Final Discussion (PAHP)

The Pembahasan Akhir Hasil Pemeriksaan is the last formal stage before the Laporan Hasil Pemeriksaan is finalized. The company is invited to discuss the examination findings with the audit team. The entire closing and reporting period, from SPHP issuance to LHP, is capped at 30 working days. If a company does not respond to the SPHP or does not attend the PAHP, it is deemed to have accepted all findings in their entirety. Silence is legal consent.

Stage Six: The Tax Assessment (SKP)

The Surat Ketetapan Pajak is the final output. An SKPKB confirms underpayment; an SKPN confirms nil position; an SKPLB confirms overpayment. The content of that document is determined not by the auditor’s discretion alone, but by the quality of the company’s documentation and the coherence of its argumentation across every stage that preceded it.

Why So Many Companies Fear a Tax Audit and Choose to Avoid One

The fear of a tax audit is rarely about the process itself. It is about what the process will expose. For foreign companies in particular, the gap between operational reality and tax documentation tends to accumulate over years of managing locally without specialist tax oversight.

The most common failure points are:

• Inadequate documentation for routinely corrected expenses. Promotional and entertainment costs without a nominative list, expenses without a clear business nexus, or in-kind employee benefits without supporting internal policy are easy targets for fiscal correction. Every correction that survives a tax audit is a correction the company’s own documentation failed to prevent.
• No equalization workpaper. The equalization, reconciling reported revenue in the annual CIT return against total revenue declared in VAT returns, and reconciling withholding tax objects against related expense accounts, is the single most effective preparation tool for any tax audit. A company that has run this reconciliation and can explain every difference in advance has eliminated the most common category of tax auditor questions before they are asked.
• No qualified staff to handle the audit. Many tax disputes in Indonesia are lost not because the underlying position was indefensible, but because no one competent enough was available to prepare a timely response. The five-day SPHP deadline under PMK 15/2025 is not the place to discover that the company does not have tax staff capable of handling it.

Building Audit Readiness as Ordinary Practice

The companies that move through tax audits most efficiently are not the ones that react best under pressure. They are the ones that do not need to react under pressure, because the documentation that an auditor would ask for already exists, is organized, and can be retrieved quickly.

That means maintaining a reconciliation between SPT Tahunan and SPT Masa PPN positions throughout the year, not reconstructing it in the week before a response is due. It means preparing a nominative list for every entertainment and promotional expense as those expenses occur, not assembling them from memory months later. It means knowing, at any given month, that the withholding tax objects in the company’s expense accounts reconcile with what has been reported as Article 21, 23, and 26 withholding.

XPND works with companies in Indonesia on the preparation work that makes audits manageable rather than disruptive: equalization workpapers, preliminary self-assessment before submitting refund claims, documentation review, and full-process accompaniment from SP2 notification through PAHP. Reach out to the XPND tax team to assess where your documentation stands before the next examination cycle begins rather than after the letter has already arrived.
