The Coretax system has digitally transformed the reporting procedures for fiscal reconciliation within the Corporate Income Tax (CIT) Annual Returns. Taxpayers are required to map their commercial financial statements into twelve specific business sector subcategories. Users must input the appropriate Positive Fiscal Adjustment (FPO) and Negative Fiscal Adjustment (FNE) codes when performing numerical corrections. Coretax introduces a multi-code feature, allowing for the simultaneous application of various correction types to a single accounting line item. Companies must strictly adhere to the guidelines set forth in PER-11/PJ/2025 to mitigate audit risks resulting from the selection of incorrect adjustment codes. .
This article will thoroughly explore the new mechanism, presenting the complete list of FPO and FNE codes according to PER-11/PJ/2025, along with technical case illustrations.
The main foundation for this change is regulated in Director General of Taxes Regulation Number PER-11/PJ/2025 concerning the Form, Content, and Procedures for Filling Periodic Tax Returns and Annual Tax Returns, as well as Minister of Finance Regulation Number 81 of 2024.
In Coretax, Commercial Financial Statements and Fiscal Reconciliation are combined into a single workflow in Attachment 1 (L1). This system demands transparency where every fiscal correction—both positive and negative—must be defined with a specific Fiscal Adjustment Code,. This aims to standardize supervision data and minimize interpretation errors between Taxpayers and the fiscus (tax officers).
Taxpayers must understand that the Financial Statement format in Coretax is divided into 12 sub-categories based on business sectors to accommodate different account characteristics, namely,:
In the Profit & Loss Statement form in Coretax, Taxpayers are required to select an adjustment code if filling in the fiscal correction column. Here are the complete details of FPO (Positive Fiscal) and FNE (Negative Fiscal) codes available in the system:
These corrections are made for costs that are expensed according to commercial accounting but are not deductible according to fiscal provisions (Income Tax Law Article 9), thus increasing taxable profit.
| Code | Description | Explanation |
|---|---|---|
| FPO-01 | Personal Interest Expenses | Costs charged/expended for the personal benefit of the Taxpayer or their dependents (Article 9 paragraph (1) letter i Income Tax Law),. |
| FPO-02 | Personal Insurance Premiums | Health, accident, life, endowment, and scholarship insurance premiums paid by the Taxpayer (if treated as private drawings/dividends),. |
| FPO-03 | - | This code is not used/removed in the latest version. |
| FPO-04 | Related Party Compensation | Amounts exceeding reasonableness paid to related parties in connection with work performed,. |
| FPO-05 | Grants/Donations | Grants, aid, or donations that do not meet the requirements to be expensed (Article 9 paragraph (1) letter g Income Tax Law),. |
| FPO-06 | Income Tax | Income Tax (PPh) expenses recorded as commercial costs,. |
| FPO-07 | Salary to Owners | Salaries paid to members of partnerships, firms, or CVs whose capital is not divided into shares. |
| FPO-08 | Administrative Sanctions | Administrative sanctions in the form of interest, fines, and surcharges, as well as criminal sanctions in the form of fines related to the implementation of tax laws,. |
| FPO-09 | Depreciation Difference (Comm > Fiscal) | Difference where commercial depreciation calculation is greater than fiscal depreciation calculation,. |
| FPO-10 | Amortization Difference (Comm > Fiscal) | Difference where commercial amortization calculation is greater than fiscal amortization calculation,. |
| FPO-11 | 3M Costs for Final/Non-Object Income | Costs to obtain, collect, and maintain income subject to Final Income Tax and income not constituting a tax object,. |
| FPO-12 | Other Positive Fiscal Adjustments | Other adjustments based on Article 4 and Article 9 of the Income Tax Law, such as costs without valid supporting documents (nominative list),. |
These corrections are made to reduce fiscal profit, usually due to differences in revenue recognition or depreciation methods where fiscal recognition is larger.
| Code | Description | Explanation |
|---|---|---|
| FNE-01 | Final/Non-Object Income in Revenue | Income subject to Final Income Tax and income not constituting a tax object but included in commercial turnover figures,. |
| FNE-02 | Depreciation Difference (Comm < Fiscal) | Difference where commercial depreciation is lower than fiscal depreciation (Fiscal depreciation cost is larger),. |
| FNE-03 | Amortization Difference (Comm < Fiscal) | Difference where commercial amortization is lower than fiscal amortization,. |
| FNE-04 | Other Negative Fiscal Adjustments | Other negative adjustments allowed by tax provisions,. |
In the Profit & Loss Statement form in Coretax, each account row (e.g., "Salary Expenses" or "Other Income") has the following columns that must be filled out horizontally:
Filling in the Fiscal Adjustment Code is mandatory if the Taxpayer enters numbers in the Positive or Negative Fiscal Adjustment columns. If the correction column is filled with numbers but the code is left blank, the Coretax system will not allow data saving (Save Draft).
One of Coretax's advantages is the ability to select more than one adjustment code in a single expense or income account. For example, in one "Other Expenses" account, there are corrections for donation costs (non-deductible) and tax penalties. Taxpayers can select two different codes for that single account row, making the correction details very clear.
Here are examples of code application for PT. Maju Terus for the 2025 Tax Year.
Data: In the "Other Operating Expenses" account (Code 5399) worth IDR 100,000,000, there are tax administrative sanction costs of IDR 30,000,000 and Corporate Income Tax costs of IDR 50,000,000. The remaining IDR 20,000,000 are deductible operating costs.
Steps in Coretax,:
Data: The "Depreciation Expense" account (Code 5314) has a commercial value of IDR 60,000,000. Meanwhile, the fiscal depreciation calculation is IDR 100,000,000. There is a difference of IDR 40,000,000 (Fiscal is larger).
Steps in Coretax,:
Data: Time Deposit Interest Income of IDR 200,000,000 is recorded as other income.
Steps in Coretax,:
Note: Filling this column automatically zeroes out the Fiscal Value for that account. There is no need to fill in the Negative Fiscal Adjustment column FNE-01 if it has been allocated to the "Subject to Final Tax" column, unless extracting costs related to that final income in the expense account (FPO-11).
The implementation of FPO and FNE Adjustment Codes in Coretax requires Taxpayers to map commercial expense accounts to standard Coretax accounts with precision. The multi-code feature provides ease in detailing a single expense account containing various types of corrections without needing to split accounts in commercial bookkeeping.
Taxpayers are advised to always refer to PER-11/PJ/2025 when determining codes, as incorrect code selection can trigger risk of inquiries or audits (audit trigger). Ensure internal reconciliation working papers are kept neatly as supporting data for the codes selected in the Coretax system.
