Winning the Appeal: Challenging the Accuracy of Tax Authority’s Annual Equalization Method Applied to a Single Tax Period

Tax Dispute on Final Income Tax Article 4(2) and General Ledger Equalization

The tax dispute between PT KLJ and the Directorate General of Taxation (DGP) highlights a fundamental evidentiary conflict regarding the objects of Final Income Tax Article 4(2) for the December 2019 tax period, arising from General Ledger equalization. The tax authority established a significant correction by assuming that balances in the "buildings under construction" and "contractor costs" accounts constituted construction service objects for which tax had not been withheld. However, this dispute became critical when the DGT attributed the entire year's equalization findings solely to one tax period (December), a move that formally contradicts the principle of periodicity in Indonesian tax law.

Core Conflict on Transaction Classification and Supporting Evidence

The core conflict centered on transaction classification and supporting documentation. The DGT insisted that the cost account balances reflected the delivery of construction services, which are subject to Final Income Tax withholding under Government Regulation No. 51/2008. Conversely, the Taxpayer provided robust evidence during the trial, proving that the majority of these values were purely material purchases (goods) and transactions whose tax liability occurred outside the December 2019 period. The DGT's inability to provide detailed counter-evidence against the documents presented by the Taxpayer became the primary weakness in maintaining their correction.

Legal Consideration of the Tax Court Judges on Audit Evidence Quality

The Tax Court Judges provided a legal consideration focusing on Article 29 paragraph (2) of the KUP Law regarding the quality of audit evidence. The Panel emphasized that equalization must not be performed haphazardly without considering the material evidence of each transaction. The physical examination of documents during the trial proved the Taxpayer's arguments to be correct, leading the Panel to cancel the entire correction. This ruling reaffirms that in withholding tax disputes, evidence such as Invoices and Bank Transfer Proofs holds significantly more weight than mere account equalization results from the General Ledger.

Policy Implications and Lessons for Construction Tax Compliance

The implications of this ruling provide a valuable lesson for Taxpayers to always maintain orderly documentation separating goods and services, particularly in construction projects. From a policy perspective, it serves as a reminder for tax authorities to be more precise in determining tax liability per tax period and to avoid using a "blanket" approach through annual equalization. This victory demonstrates that administrative compliance supported by valid physical evidence is the best defense in facing tax litigation.
