The Directorate General of Taxes implements equalization techniques to validate compliance with Article 23 Income Tax withholding by third parties. Tax auditors synchronize expense records in the Income Statement with the taxable base in the Unified Monthly Tax Returns. The authority utilizes the crediting of Input Tax Invoices as a cross-checking tool to detect service transactions that escaped withholding. The auditor will issue an Underpayment Tax Assessment Notice if the taxpayer fails to legally clarify the discrepancy found. Taxpayers must prepare monthly equalization working papers and separate material values within invoices to prevent the risk of fiscal corrections..
In the framework of tax supervision and audit in Indonesia, specifically under the regime of Minister of Finance Regulation Number 15 of 2025, data validity is the main pillar. One of the testing techniques most frequently used by Tax Auditors to test third-party withholding tax compliance is Equalization.
The focus of this discussion is the technical equalization technique between expense accounts in the Financial Statements (Corporate Income Tax/CIT Return) and the Tax Base (DPP) of PPh Article 23 (Income Tax Art. 23) reported in the Unified Periodic Tax Return cumulatively for one tax year. This technique is technically regulated in SE-65/PJ/2013 concerning Guidelines for the Use of Audit Methods and Techniques and various technical modules of the Directorate General of Taxes (DGT).
PPh Article 23 Equalization is an analytical procedure to ensure that all payments for services, rentals, dividends, interest, and royalties expensed by the company have been withheld according to the applicable rates (2% or 15%).
Fundamentally, this audit bridges two different recording bases:
The discrepancy between these two figures—without adequate reconciliation—is a risk indicator (red flag) for Tax Auditors that there is potential unpaid tax.
The audit procedure begins with dissecting the Taxpayer's Financial Statements. Based on the Profit and Loss Audit Program, the Auditor will map General Ledger (GL) accounts that are naturally PPh Article 23 objects.
The main target accounts include:
Referring to the standard audit working papers in SE-08/PJ/2012 and guidelines in SE-65/PJ/2013, here are the technical steps taken by the Auditor:
The Auditor sums up the expense account balances mapped above from the Profit and Loss Statement.
Initial Formula: Total Rent Expenses + Total Service Expenses + Interest + Royalties.
The CIT figure must be adjusted with the following variables to obtain the "PPh 23 Objects that Should be Withheld" figure:
The calculated figure above is compared with the accumulated Gross Income listed in the PPh Article 23 Withholding Slips from January to December.
Difference (Correction) = DPP According to Auditor - DPP Reported in Periodic Return.
One of the most sophisticated techniques emphasized in audit training materials is Equalization of PPh 23 Objects with Input VAT. Logikanya sederhana namun mematikan: If a Taxpayer credits Input Tax Invoices for the acquisition of Taxable Services (JKP) or Rentals, then automatically the transaction is a PPh Article 23 object.
Procedure:
In the final discussion of audit results, Taxpayers often face these equalization findings. Here are the main issues and how to resolve them:
If the difference cannot be explained, the Auditor will issue an Underpayment Tax Assessment Notice (SKPKB) for PPh Article 23. In addition to the principal tax (2% or 15%), the Taxpayer will be subject to administrative sanctions in the form of interest.
Under PMK 15 of 2025, this finding can trigger an expanded audit to test the validity of those costs in CIT (deductibility), especially if the counterparty is unclear.
PPh Article 23 Equalization is not merely matching final figures, but testing the consistency of transaction flows. The best strategy is to perform self-equalization monthly. Ensure every service/rent expense has a Withholding Slip reference, and every Input VAT crediting for Services is followed by a PPh 23 Withholding Slip.
