Revenue Wins vs. Expense Losses: Critical Lessons from PT IS’s Tax Dispute on e-Faktur Administration and Accrued Expenses 

Tax Ruling: Accounting Substance vs. e-Faktur Discrepancies (PT IS Case)

The Corporate Income Tax dispute of PT IS highlights the critical synchronization between e-Faktur administration and accounting substance, as well as the judicial limits of expense deductions under Article 9 of the Income Tax Law.

The Conflict: e-Faktur Mismatches and Accrued Audit Fees

The DGT identified sales discrepancies through e-Faktur reconciliation, arguing that tax invoices should dictate the tax base. PT IS countered that the mismatch was merely a data migration error in discount layering and that their books showed the true net value. Furthermore, the DGT disallowed 2018 audit fees because the formal invoice was only issued in 2019, classifying the expense as a non-deductible reserve.

Judicial Consideration: Material Truth vs. Certainty of Liability

The Board of Judges provided a nuanced resolution:

• For Revenue: The Board accepted PT IS’s general ledger and accounts receivable cards. They ruled that administrative errors in e-Faktur do not override the material truth of the accounting records.
• For Audit Fees: The Board sided with the DGT. While the accrual basis is allowed, expenses must represent a certain liability. Since the audit was not finalized by year-end, the accrual was deemed a prohibited reserve.

Implications: Accounting Supremacy and Accrual Discipline

This decision emphasizes that accounting substance remains supreme in turnover disputes. However, it serves as a stern warning regarding year-end accruals. Taxpayers must ensure that professional service charges are supported by verifiable work progress or definitive billing to avoid them being reclassified as non-deductible reserves.

Conclusion

In conclusion, administrative discipline in e-Faktur is vital to prevent audits, but the strength of the General Ledger is the ultimate defense for revenue. Conversely, for expenses, "accrual" is not a blank check; it requires a level of certainty that an estimation often fails to provide under fiscal scrutiny.
