Banking Strategy Against Final Income Tax Corrections: Winning through Customer Account Evidence Below 7.5 Million Rupiah

Legal Dispute Analysis: Final Income Tax Thresholds vs. Bank Secrecy

The Tax Authority's positive correction of interest expenses often overlooks the specific threshold limits regulated under special Final Income Tax provisions. Based on an in-depth examination of general ledgers and detailed customer data, this dispute focuses on whether each deposit account met the cumulative criteria to be exempted from tax withholding according to applicable regulations.

The Conflict: Detailed Proof vs. Confidentiality

The core conflict in this case began with the Tax Authority's (Respondent) correction of interest expenses amounting to IDR 1,023,957,365:

• Respondent's Argument: The Taxpayer (Appellant) failed to provide detailed customer identities (names and addresses) to validate that the interest originated from deposits below the threshold.
• Appellant's Defense: These costs were an accumulation of interest from thousands of customers with balances below the threshold stipulated in Article 3, paragraph (1), letter a of Government Regulation No. 131 of 2000. The Appellant refused to disclose names to maintain bank secrecy but provided account numbers for cross-examination.

Judicial Review: Validity of Account Numbers as Evidence

In its legal considerations, the Board of Judges conducted a factual examination of interest details per account:

1. Factual Findings: The Judges found that none of the deposits in the list exceeded the IDR 7,500,000 limit.
2. Legal Conclusion: The Board opined that as long as the value criteria are met, the obligation to withhold Final Income Tax does not arise.
3. Decision: The Respondent's correction was declared to have no strong legal basis and was overturned.

Implications: Legal Certainty for Banking Institutions

This decision provides legal certainty for banking institutions that account number details, without specifying customer names, remain acceptable as valid evidence in tax court, provided the data is consistent with the general ledger. This decision serves as an important precedent in the application of the Final Income Tax withholding threshold for small-scale public savings interest.

Conclusion: The Tax Court prioritized material criteria (deposit amount) over formal identity requirements. This victory strengthens the position of banks in protecting customer privacy while remaining compliant with tax object thresholds.
