Understanding Attachment 3 in Coretax DJP Online
Many PT PMA business owners find Attachment 3 income form confusing when submitting their annual tax report Indonesia. It’s part of the Coretax DJP Online system where you summarize your company’s income, deductions, and adjustments .
Attachment 3 helps the Directorate General of Taxes (DGT) verify your business performance and calculate your correct tax obligations. Inside, you’ll see columns for “gross income,” “net correction,” and “final calculation.” Each one must be filled precisely to prevent future audit issues.
Think of this as a summary sheet—a quick look at your company’s yearly financial story . When done correctly, it speeds up your e-filing approval and even improves your chance for faster tax refunds. Always double-check numbers and match them with the main form (1770 or 1771) before submission.
The Attachment 3 income form in Coretax DJP Online has three essential sections: income details, correction entries, and deductions. Each part connects directly to your accounting records .
In the first section, you record gross income from all operations — sales, services, and other business activities. The next section adjusts any differences between accounting and tax rules, such as non-deductible expenses or tax incentives .
Finally, deductions like operational costs, salaries, and depreciation are entered before calculating taxable income. Remember, every number must align with your accounting system to avoid discrepancies in your annual tax report Indonesia. Using accounting software or consulting a professional can ensure accuracy .
Reporting income in Coretax DJP Online requires accuracy and consistency. Begin by reconciling your accounting books with your tax records. Make sure all invoices, receipts, and payments match what’s reported in Attachment 3.
Gross income should include all business revenue, even those received in foreign currency . If your PT PMA earns money from abroad, convert it into Rupiah using the official exchange rate from the Ministry of Finance.
Be cautious with “other income” fields—these must be clearly justified, such as investment returns or asset sales. Incorrect entries may trigger Coretax system errors or rejection messages . Always save screenshots of submissions for your records.
Filing the annual tax report in Indonesia can be stressful, especially if you make small but costly mistakes. Many PT PMA owners forget to align the totals in Attachment 3 with the figures in their main return forms .
One frequent error is misplacing figures between “gross” and “net correction” columns. Others accidentally leave out foreign income or double-report the same deductions. These errors can cause Coretax DJP Online to flag your file for manual review, delaying tax clearance.
To avoid problems, always check the Directorate General of Taxes instructions before uploading. Reviewing previous filings and keeping backup copies also help maintain compliance. Consistency is key to a smooth reporting experience .

For PT PMA entities, Coretax DJP Online can simplify compliance—but only if used correctly. Always update company details before starting the Attachment 3 income form to avoid validation issues .
Assign a trained staff member or tax consultant familiar with the system. PT PMA firms often face extra scrutiny from the Directorate General of Taxes, so proper documentation is crucial. Use the “Preview” option to check for missing or mismatched figures .
Lastly, file early! Waiting until the last week of March (for corporate taxpayers) risks system overloads and slower processing. Early filing also gives time to correct errors before submission deadlines.
Deductions in Attachment 3 income form play a major role in lowering taxable income. Legitimate deductions include salaries, rent, professional fees, and depreciation .
However, not all business expenses are deductible. Personal costs, entertainment, or unrecorded expenses may be disallowed by the Directorate General of Taxes . Always provide receipts or contracts as proof.
Using Coretax DJP Online makes it easier to attach supporting documents digitally . A well-documented deduction strategy not only reduces your tax burden but also strengthens your compliance position during audits. The clearer your data, the smoother your tax season.
