SP2DK Indonesia: What It Means in English and How to Respond

SP2DK Indonesia refers to a letter from the Indonesian tax office (Direktorat Jenderal Pajak, DJP) asking a taxpayer to explain data or information it holds. SP2DK in English is a “request for explanation of data and/or information”, from the Indonesian Surat Permintaan Penjelasan atas Data dan/atau Keterangan. It is not a tax assessment and not yet an audit, but it needs a timely, documented answer. This guide explains what an SP2DK is, what Ministry of Finance Regulation No. 111 of 2025 (PMK 111/2025) changed, and how to respond.

What Is SP2DK in Indonesia?

An SP2DK is a letter issued by the DJP, through the local tax office (KPP), asking a taxpayer to clarify or fulfil a tax obligation where the DJP’s data suggests a gap. The letter normally comes with a findings table that sets out the tax type, the tax period and the amount the DJP wants explained. Under PMK 111/2025 (Article 5), it can be delivered through the taxpayer’s account (Coretax), to the email address registered with the DJP, by fax, by post or courier, or by hand to the taxpayer or its representative.

The regulation uses only the Indonesian name and does not give an official English name for the letter. “Request for explanation of data and/or information” is a translation used in practice, so use the Indonesian abbreviation when you talk to the tax office.

What PMK 111/2025 Changed

Before 2026, SP2DK procedures sat mainly in a DJP circular, SE-05/PJ/2022. Since 1 January 2026, PMK 111/2025 on tax compliance supervision applies, which puts the process in a Ministry of Finance regulation. Points that matter for a company:

• Response period: at most 14 days, counted from the earlier of the letter’s issue date (when delivered through the taxpayer account) or the date it was sent by email, fax, post or courier, or handed over (Article 6).
• Extension: the taxpayer may extend by up to 7 days by giving written notice to the issuing KPP, and the notice must reach the KPP before the original period ends.
• More than one reply: a taxpayer may respond more than once within the period.
• Recipients: the letter can also go to taxpayers that are not registered yet, for example a business that has not obtained a tax number.

The 14 days are not described as calendar days in the regulation text. The old circular used calendar days, so count calendar days to stay safe.

Why SP2DK Indonesia Exists in the Coretax Era

The DJP bases its supervision on the results of reviewing data and information it holds, and it can request data from third parties (PMK 111/2025, Articles 3 and 4). Coretax, the DJP’s core tax administration system, gives it one place to match returns, invoices, withholding slips and other records, and the regulation allows parts of supervision to run through the DJP’s administration system. The practical result is that mismatches are more likely to be found, and a letter arrives sooner than a full audit would.

Common Triggers for SP2DK Indonesia

The regulation does not list triggers. In practice, an SP2DK follows when the DJP’s data does not match what a taxpayer reported or paid. Typical examples:

• revenue in the annual return that is lower than the revenue indicated by tax invoices or third-party data;
• withholding tax that was due but not withheld, deposited or reported (see our guide to PPh 21 in Indonesia);
• VAT credits that do not match supplier data (see VAT in Indonesia for foreign companies);
• payments abroad that are not matched by withholding, such as royalties and management fees (see withholding tax on royalties);
• late or missing returns, which can also lead to a warning letter.

Your Rights and Obligations When Receiving SP2DK

You must respond within the period stated in the letter, and the answer can be to fulfil the obligation, to explain it, or both. If you disagree with the DJP’s findings, the explanation must include supporting evidence or documents.

You may use any of these channels (PMK 111/2025, Article 6):

• your Coretax taxpayer account, if it is active and the channel is available;
• post or courier to the KPP;
• in person at the KPP, or during an officer’s visit;
• a video conference.

You can also correct a tax return on your own. Under the General Tax Provisions Law (Article 8), voluntary correction is allowed as long as the DJP has not started an audit. If a correction increases the tax due, interest applies on the underpaid tax, at a monthly rate set by the Minister of Finance, for up to 24 months. The rate is based on the reference interest rate plus 5%, divided by 12.

How to Respond to SP2DK: A Step-by-Step Approach

Step 1: Read the SP2DK carefully before doing anything else

Note the issuing KPP, the date of the letter, the date it reached you, the response period and every item in the findings table. The deadline starts counting from the delivery event, not from the day you read the letter.

Step 2: Reconcile your records internally

Compare each finding against your returns, tax invoices, withholding slips, contracts and accounting records. Many SP2DK findings come from mismatched data rather than unpaid tax. Our guides to annual tax reporting compliance and financial reporting for foreign companies help with this step.

Step 3: Decide the type of response

You have two main options for each finding:

• Agree and fulfil: file a corrected return or pay the amount, where the DJP is right.
• Explain with evidence: where the DJP’s data is wrong or incomplete, explain and attach documents.

A mixed response is common: agree on some findings and explain others.

Step 4: Prepare the documentation

Write a clear response letter that answers each finding in the order of the findings table. Attach evidence for each point, such as invoices, contracts, bank statements or a reconciliation schedule. Keep a copy of everything you send.

Step 5: Submit through a valid channel before the deadline

If you need more time, send the written extension notice early, because it must reach the KPP before the original period ends. If the SP2DK came through Coretax, responding through Coretax is the cleanest option, since the system records proof that the KPP received it. Keep that proof.

What Happens After You Respond

The DJP reviews your response. If it matches the letter, the process is documented in minutes. If your answer does not match the letter, new data appears, or you did not respond, the DJP may invite you to a meeting or send officers on a visit. The possible outcomes of supervision are listed in the regulation. They include closing the request through a progress notice, changing or correcting data, an examination, or a preliminary evidence examination. Practitioners call the closing notice SP3P2DK, though the regulation uses the full name, a notice of progress on the implementation of the request for explanation.

SP2DK Is Not a Tax Audit: Understanding the Difference

An SP2DK is a supervision step. An audit (pemeriksaan) is a separate process that ends in an assessment letter (SKP) if the DJP finds underpaid tax. The two are linked: under PMK 111/2025, examination is one possible outcome of supervision. The difference matters for corrections. The General Tax Provisions Law lets you correct a return voluntarily only until an audit starts, and once an audit has started the disclosure route is narrower and the audit continues. Responding well at the SP2DK stage is therefore the cheapest point to put the record right.
