Tax Court Win! Tax Corrections Based on Estimation Data Overturned by Judges

Legal Dispute Analysis: Internal Projections vs. Actual Transactional Basis

The Directorate General of Taxation (DGT) often utilizes a taxpayer's internal data found during audits to perform revenue corrections via extrapolation methods. However, the case of PT TTMEI highlights that using "Summary Sales" data without supporting evidence represents a critical legal weakness for the authority.

The Conflict: "Summary Sales" – Actual Revenue or Business Estimate?

The conflict originated from a VAT Base (DPP) correction of IDR 463,141,251.00 based on internal working documents:

• Respondent's Position (DGT): Argued that the "Summary Sales" document represented actual transaction values. Citing Article 29 of the KUP Law, they maintained that since the taxpayer could not provide adequate refuting evidence, the data was valid for determining tax liability.
• Petitioner's Defense (PT TTMEI): Emphasized that the document was merely an internal estimate or business projection. They argued that all actual deliveries had been accompanied by Tax Invoices and accurately reported, meaning no taxable delivery had yet materialized from that specific document.

Judicial Review: The Principle of Fair Burden of Proof

The Board of Judges rejected the use of administrative projections as a basis for taxation:

1. Lack of Concrete Evidence: The Board opined that the DGT was unable to demonstrate concrete evidence of cash flow or goods flow supporting the figures in the "Summary Sales."
2. Legally Unsustainable Assumptions: Without third-party confirmation or physical delivery evidence, corrections based solely on extrapolation are deemed legally unsustainable.
3. Consistency of Records: The Petitioner successfully demonstrated a clear link and consistency between their accounting records, financial statements, and issued Tax Invoices.

Implications: Protecting Taxpayers from Unilateral Corrections

This decision underscores that the strength of evidence in tax disputes relies heavily on physical reality, not administrative potential:

• Evidence Hierarchy: Fund flows and physical delivery evidence take precedence over internal "working papers."
• Administrative Discipline: Taxpayers must maintain strict discipline in separating projection/estimate data from actual realization data to mitigate future dispute risks.

Conclusion: The Tax Court overturned the Respondent's entire correction. This victory reinforces the principle of Substance Over Form: tax liability is born from the reality of an exchange, not from an internal planning document.
