Public Accountant’s Error Causes IDR 20 Billion Tax Correction: The Key to a Taxpayer’s Victory Against Assumptive Cash Flow Testing

The Tax Court Panel adopted a position supporting the principle of consistent bookkeeping and the burden of proof inherent in the DJP. In accordance with Article 78 of the Tax Court Law, the Panel opined that the DJP failed to meet the burden of proof to sustain its correction. DJP's correction was deemed presumptive because it was based solely on one item in the Cash Flow Statement (a secondary report in the context of accrual-based CIT) without adequate substantive testing, such as reconciliation to the Bank Book or a deep analysis of the General Ledger. The Panel believed that an account classification error by the KAP could not automatically be used as the basis for a Revenue correction, especially when PT MLY could present detailed primary bookkeeping documents (the General Ledger) proving otherwise.

This decision has important implications for tax litigation practices, particularly concerning disputes over cash flow testing results. First, it emphasizes that the DJP cannot partially use cash basis data from one financial statement (like the Cash Flow Statement) to correct accrual-based income (Income Statement) without conducting comprehensive substantive testing. Second, the case sets a precedent for Taxpayers to defend the integrity of their General Ledger as the primary bookkeeping document. DJP's failure to present adequate Examination Working Papers (KKP) and the absence of substantive testing were key factors in the correction’s cancellation, affirming that the burden of proof remains on the party issuing the correction.

PT MLY’s victory in this dispute underscores the importance of consistency in applying the accrual principle and the necessity for the DJP to base corrections on convincing facts and evidence, not on assumptions arising from third-party classification errors. For Taxpayers, the key takeaway is the absolute requirement for strong documentation, including official statements from the KAP regarding any corrections made, to successfully refute presumptive corrections.
