How InCorp Indonesia Supported the SP2DK Process The Result: Proposed Tax Correction Reduced by 92% Why SP2DK Should Be Addressed Before It Escalates Conclusion Frequently Asked Questions A complex tax issue, such as SP2DK, can create significant exposure to the tax office (the Directorate General of Taxes, or DJP). The authority may identify a discrepancy between a company’s tax reporting and the information available in its system. In this case study, InCorp Indonesia (an Ascentium Company) assisted an Indonesian IT services company in responding to an SP2DK. Inside the letter, questions were raised concerning intercompany expenses paid to overseas parties. Through a detailed case review, supporting documentation, technical tax analysis, written explanations, and clarification meetings with the DJP, the proposed tax correction was reduced by approximately 92%. The matter was resolved during the SP2DK clarification stage without proceeding to a tax audit, tax investigation, or further dispute process. Key Takeaways The proposed tax correction was reduced by approximately 92%. The SP2DK case study was resolved at the SP2DK clarification stage without progressing to a tax audit, tax investigation, objection, or appeal. The SP2DK review covered one tax year and focused on intercompany expenses paid to overseas parties. Written explanations, clarification meetings, and a key supporting document helped support the company’s position. SP2DK Case Study Overview Item Details Client Type Indonesian IT services company Company Structure PT PMDN Tax Period Reviewed One tax year Main SP2DK Issue Deductibility of intercompany expenses paid to overseas parties Initial Risk Significant proposed tax correction Support Provided Case assessment, document review, written explanations, technical tax analysis, and clarification meetings Outcome Proposed correction reduced by approximately 92% Escalation Status Resolved without a tax audit or tax investigation What Triggered the SP2DK? As part of the SP2DK process, the tax office requested confirmation, clarification, and explanations regarding discrepancies between the company’s tax reporting and the data available in the Directorate General of Taxes (DJP) system. The review covered one year of tax, with one of the main concerns involving intercompany expenses paid to overseas parties. The issue involved different views on the deductibility of these expenses: The Company’s Position: The expenses were related to its business activities and were therefore considered deductible for tax purposes. DJP’s Position: The DJP took a different view, proposing a significant tax correction. Potential Risk: If the questions were not adequately addressed, the matter could progress beyond the SP2DK clarification stage. The company therefore needed to demonstrate that its tax reporting reflected the actual transactions and was supported by relevant explanations, information, and documentation.

Presented the Key Supporting Document During the final meeting, the team presented a key supporting document based on its understanding of the facts and the overall case flow. After reviewing the document, the DJP agreed with the company’s position and withdrew most of the proposed tax exposure. The Result: Proposed Tax Correction Reduced by 92% The matter was successfully resolved during the SP2DK clarification process. The result included: An approximately 92% reduction in the proposed tax correction Resolution covering the reviewed tax year No escalation to a tax audit No escalation to a tax investigation No ongoing objection, appeal, dispute, or other active proceeding The outcome was achieved through a combination of case analysis, supporting documentation, technical tax explanations, written responses, and direct clarification with the DJP. Why SP2DK Should Be Addressed Before It Escalates This SP2DK case study shows that a significant proposed tax correction can still be addressed during the clarification stage when the company has a supportable tax position. However, a strong response requires more than a general explanation. Companies need to: Understand the specific concerns raised by the tax office Assess the potential tax exposure Review the facts behind each transaction Identify the relevant supporting documents Prepare a clear technical explanation Maintain consistency throughout the written response and clarification meetings This is especially important when the SP2DK concerns intercompany or overseas transactions, where the company may need to explain the business purpose of the expenses and support the tax treatment applied. Addressing the issues early gives the company a better opportunity to clarify its position. At the same time, the matter remains at the SP2DK stage, before it progresses to a tax audit or other further proceedings.

The earlier the issues are assessed, the more time the company has to reconstruct documents, identify exposure, and prepare a consistent explanation.

SP2DK stands for Surat Permintaan Penjelasan atas Data dan/atau Keterangan. It is a letter issued by a tax office (Directorate General of Taxes, or DJP) requesting an explanation of data or information related to a taxpayer’s compliance obligations. Does receiving an SP2DK mean a company has violated tax rules? No. An SP2DK is a request for clarification and is not, by itself, a tax assessment or a final finding that the taxpayer has committed a violation. The company is allowed to explain the relevant data and support its reported position. How long does a company have to respond to an SP2DK? DJP’s current digital service guidance states that taxpayers must respond or provide an explanation within 14 days. Companies should confirm the applicable deadline shown in the letter and begin reviewing the issues immediately. Can an SP2DK be resolved without a tax audit? Yes. When the discrepancies are adequately explained and supported, an SP2DK may be resolved during the clarification process. In this SP2DK case study, the matter was concluded without proceeding to a tax audit or investigation. What transactions were questioned in this SP2DK case study? The main issue concerned intercompany expenses paid by an Indonesian IT services company to overseas parties. The DJP questioned whether the expenses qualified as deductible business costs. Why are overseas intercompany expenses questioned? The DJP may examine whether the expenses are genuine, connected with business activities, adequately documented, and consistent with the company’s accounting and tax reporting. Companies may need to prove the substance of the transaction and the benefits received, rather than merely provide invoices. Can an SP2DK be answered only in writing? Some matters may be addressed in writing, but meetings may still be necessary where the tax officer requires further clarification. In this case, the written explanation was followed by several discussions and a final meeting that led to resolution. What documents may be needed to respond to an SP2DK? The required documents depend on the issue. They may include agreements, invoices, payment records, accounting ledgers, correspondence, work products, transaction calculations, tax returns, and evidence demonstrating the commercial purpose or benefit of the expense. Should a company voluntarily correct its tax return after receiving an SP2DK? Not automatically. The company should first assess whether the discrepancy reflects an actual reporting error or whether the reported position can be supported. Filing a correction without understanding the issue may create an unnecessary tax liability or an inconsistent record. Can InCorp Indonesia assist with only one SP2DK case? Yes. Companies can engage InCorp Indonesia for a specific SP2DK matter without outsourcing their full tax or accounting function. The scope can cover risk assessment, document preparation, written responses, meetings, and follow-up support.
