The correction of the Income Tax Article 23 tax base conducted ex-officio through extrapolation methods without the support of source document evidence is an administrative action highly susceptible to being overturned in court. This dispute focuses on the determination of tax objects in the form of management services by the Respondent against Koperasi Perkebunan Kelapa Sawit Mitra Gaga Begulai (KPKSMGB), which was based on third-party data without being able to demonstrate a legally or materially valid transaction reality for the December 2018 Tax Period.
The core of the conflict began when the Respondent corrected the Income Tax Article 23 tax base by IDR 1,253,251,681.00, claiming that there was utilization of management or technical services for which tax had not been withheld. The Respondent utilized extrapolation authority, alleging that KPKSMGB was uncooperative in presenting bookkeeping documents during the audit process. On the other hand, KPKSMGB firmly denied the existence of the transaction, stating that as a plantation cooperative, they had never entered into management service contracts of such value, and emphasized that the company's books reflected the actual conditions without the alleged service costs.
In its resolution, the Board of Judges emphasized that in withholding tax disputes, the burden of proof regarding the existence of the tax object lies entirely with the tax authority. After conducting a thorough examination of the evidence in the trial, the Board found that the Respondent failed to present primary source documents such as cooperation contracts, invoices, or proof of cash flow specifically referring to the service transactions in the disputed period. The Judges opined that extrapolation based solely on assumptions from third-party data without validating document flow is evidentially flawed.
The analysis of this decision shows that the Board of Judges' firmness in applying the substance over form principle and evidentiary rules is crucial to protecting Taxpayers from speculative corrections. The implication of this decision for Taxpayers is the importance of consistency between bookkeeping and field reality, as well as readiness to defend arguments if tax authorities use irrelevant external data. This decision serves as a strong precedent that third-party data cannot automatically be used as a basis for correction without supporting evidence showing the actual delivery of services.
In conclusion, the Board of Judges granted KPKSMGB's entire appeal and canceled all of the Respondent's corrections. This confirms that the validity of a tax assessment must be based on definite data and competent evidence, not merely on unverified estimates or extrapolations.
