Beware of Exchange Rates and Billing Timing! Learning from PT KSS's Victory Against a USD 68,000 Tax Correction

Can the difference between invoice issuance timing and revenue recording lead to a tax dispute worth hundreds of millions of rupiah? The answer is yes. This is exactly what was experienced by PT KSS, a shipbuilding company that had to fight in the Tax Court against the Director General of Taxes (DGT) regarding a revenue correction worth USD 68,858 (approximately IDR 1 Billion). This case provides valuable lessons for business players regarding the importance of financial data synchronization and precision in documenting every difference between accounting records and tax documents. The Taxpayer's victory in this case proves that consistency in accounting methods is the best shield against examinations.

The conflict began when the DGT deemed PT KSS to have underreported its turnover in 2017. The Tax Examiner used a commonly employed method: comparing the total invoices issued by the company with the total sales reported in the Tax Return. When a discrepancy was found, the DGT immediately assumed it was hidden sales. The DGT also rejected the company's bookkeeping evidence (General Ledger) because it was considered merely "self-made recaps." This action placed the Taxpayer in a difficult position, where the integrity of its financial data was questioned simply due to the data presentation format.

However, PT KSS did not remain silent. They proved in court that the discrepancy was merely a numerical illusion caused by two factors: timing differences and exchange rate differences. The company explained that in the world of ship construction and repair, revenue is recognized when work is completed (accrual), not when the bill is sent. Work completed at the end of December 2016 was only billed in January 2017, causing 2017 invoices to swell even though the revenue belonged to 2016. Furthermore, the company used Bloomberg rates while the tax authority used another source, creating an even wider numerical gap.

The Tax Court Panel of Judges ultimately ruled in favor of PT KSS. The Judges saw that the company's explanation was very logical and supported by strong audit evidence. The Judges rejected the DGT's argument, which merely speculated without concrete evidence that the company's bookkeeping was false. This ruling sends a clear message: as long as the company is consistent, compliant with principles, and possesses valid audit evidence, the accrual revenue recognition method must be respected by tax authorities. For entrepreneurs, this case is a reminder to always be ready with neat data reconciliation—because a single day's difference in invoice dates can trigger lengthy questions from tax officers.
