Trapped by Electricity Consumption: Why Thermodynamic Analysis Can Correct Billions in Revenue?

Tax Dispute: Thermodynamic Analysis and Indirect Methods of Audit for PT AJM

The Directorate General of Taxation (DGT) is authorized to determine tax liabilities ex-officio using indirect methods if the Taxpayer fails to maintain bookkeeping in accordance with the regulatory standards of Article 28 of the KUP Law. In the dispute of PT AJM, the Respondent applied thermodynamic analysis techniques based on electricity consumption to reconstruct the actual production volume and unreported sales revenue.

Core Conflict: Electricity Consumption Discrepancies vs. Machine Revitalization

The conflict arose when the Respondent discovered inconsistencies between electricity consumption data from PLN and the sales volume reported by PT AJM. Given that PT AJM failed to provide primary accounting documents such as the General Ledger or reliable production records during the audit, the Respondent utilized the technical assumption that every unit of electricity used is directly proportional to production output. Conversely, PT AJM countered with the argument that in 2011, there was a major machine revitalization and internal sabotage, implying that high electricity usage did not necessarily result in finished goods (machine heating without production).

Judicial Consideration: Validity of Indirect Methods Under SE-65/PJ/2013

The Board of Judges, in their legal considerations, emphasized that the use of indirect methods, including thermodynamic analysis, is legally valid under SE-65/PJ/2013 when primary data is unavailable. The Judges assessed that the evidence presented by PT AJM regarding machine revitalization was not supported by adequate accounting documents to refute the Respondent's calculations. The legal fact regarding the tax crime history of the Petitioner's Director in previous years further strengthened the Board's conviction of a systematic pattern of non-compliance.

Implications: Importance of Operational Logs in Audit Risk Mitigation

The implications of this decision are crucial for manufacturing sector Taxpayers: non-financial operational documentation, such as machine usage logs and technical repair records, holds a vital position in audit risk mitigation. Failure to present documentation that is synchronized with utility usage (electricity/water) can lead to significant revenue corrections. In conclusion, the Board of Judges rejected PT AJM's appeal and upheld all of the Respondent's corrections because the Petitioner failed to meet the burden of proof during the trial.
