Final Income Tax Compliance Audit: Technical Procedure for Equalization of Operational Expenses and Assets in Corporate CIT Returns with PPh Article 4(2) Objects

In the landscape of Indonesian tax compliance, especially following the implementation of Minister of Finance Regulation Number 15 of 2025 which emphasizes Risk-Based Audit, cross-return testing techniques have become the tax authority's primary weapon. One area with high exposure risk that is often overlooked is Final Income Tax (PPh) Article 4(2).

Unlike Income Tax Article 23 which is non-final (creditable by the recipient), PPh Article 4(2) is final. Errors in withholding cannot be corrected through a tax credit mechanism at year-end by the counterparty, making the accuracy of tax object determination crucial. This article will dissect the Equalization procedure between expense and asset items in the Annual Corporate Income Tax (CIT) Return and the Tax Base (DPP) of PPh Article 4(2) reported in the Unified Periodic Tax Return cumulatively.

This discussion is based on technical standards in SE-65/PJ/2013, guidelines for Audit Working Papers (KKP) in SE-08/PJ/2012, and the dynamics of audits in the Core Tax era.

The Urgency of PPh Article 4(2) Equalization

PPh Article 4(2) Equalization is an analytical procedure to verify whether the Taxpayer has withheld final tax on specific transactions such as:

• Rent of Land and/or Buildings: Including building service charges.
• Construction Services: Planning, Execution, and Supervision.
• Dividends Received by Individuals: (If the Corporate Taxpayer acts as the payer of dividends to individuals).
• Bond Interest: If relevant to the company's financing activities.

In an audit, the Tax Auditor uses this technique to detect unreported withholding tax. Logically, if a company records warehouse rental expenses of IDR 1 Billion in the Profit and Loss Statement, there should be a Final PPh Article 4(2) deposit with a Tax Base of IDR 1 Billion in the Periodic Return. Any unexplained discrepancy will be considered as underpaid tax objects.

Stage 1: Account Mapping and Data Sources

The initial step in the audit procedure, as outlined in the Tax Audit Preparation Training Module, is to collect and map source data. The Auditor will juxtapose the following documents:

Stage 2: Technical Equalization Calculation Procedure

Referring to the Audit Working Paper (KKP) format Index h in SE-08/PJ/2012 and guidelines in SE-65/PJ/2013, here are the technical dissection steps of equalization performed:

A. Object Identification from CIT Side (Accrual Basis)

The Auditor will pull expense account balances indicated as PPh 4(2) objects. Rent Expenses are distinguished between vehicle/machinery rent (PPh 23 Object) and land/building rent (PPh 4(2) Object). Building Maintenance Expenses are also scrutinized; minor renovations or installations attached to buildings often fall under Construction Execution Services rather than simple maintenance.

B. Object Tracing in Balance Sheet (Capitalized Items)

PPh 4(2) Construction Services is also viewed from Fixed Asset Additions. If there is an addition to "Buildings" or "Office Renovations" in the Balance Sheet, it is deemed a Construction Tax Base.

Formula: (Year-End Building Asset Balance - Beginning Balance) + Current Year Accumulated Depreciation = Current Year Acquisition/Construction Value.

C. Adjustment of Adding and Deducting Variables

Figures from the GL require reconciliation to handle timing differences:

• Additions: Prepaid Rent (recorded as assets but tax is due upon payment) and Capitalized Costs for construction.
• Deductions: Rent Amortization (payments from previous years), Pure Material Purchases (not a tax object if separated from labor), and Non-Land/Building Asset Rent.

D. Comparison with Periodic Returns

The calculated result is compared with the Total Gross Income in the Unified Periodic Tax Return. Any difference results in a correction: Difference = Tax Base According to Auditor - Tax Base Reported.

Case Study: Critical Points in Construction and Rent

As regulated in SE-10/PJ/2017, specific issues frequently trigger corrections:

Documentation and Defense

In the Closing Conference under PMK 15 of 2025, Taxpayers must prepare defense documents:

• Reconciliation Sheet: Explaining Accrual vs Cash timing differences.
• Rent and Construction Contracts: Proving the separation of material/service values and reimbursement clauses.
• PPh 23 Withholding Slips (Cross-Defense): To prevent double taxation if maintenance was already withheld under PPh 23.

Implications of Audit Results

Discrepancies lead to an Underpayment Tax Assessment Notice (SKPKB). Because PPh 4(2) is Final, related expenses must be fiscally corrected in the Corporate CIT Return as Non-Deductible Expenses, coupled with administrative interest sanctions.

Conclusion

PPh Article 4(2) Equalization is a vital bridge between financial statements and withholding obligations. Digital transparency means inconsistencies will be easily detected by DGT algorithms.
