New Changes in Online Filing of the Annual Income Tax Return in Indonesia
Individual and corporate taxpayers in the archipelago often face technical errors when submitting documents. The legacy DJP Online portal sometimes fails to process attachments correctly, leading to delayed reports. This disjointed process creates administrative uncertainty for foreign investors and local business owners alike.
Late submissions result in automatic fines and interest charges that accumulate every month. These administrative penalties threaten the residency status of expats and the financial standing of foreign-owned businesses in Indonesia. Failing to submit an accurate report on time triggers automated audits that scrutinize your entire financial history in the country.
The Coretax system introduced by the Directorate General of Taxes provides a unified portal for all fiscal obligations. This guide explains how to use the new platform for your Income Tax Return in Indonesia to ensure full compliance. By following these updated digital protocols, you ensure your business remains in good standing while reducing manual data entry errors.

Regulatory Framework of Coretax Implementation
The legal basis for the current digital transition is PER-11/PJ/2025. This regulation governs the reporting of income tax, value added tax, and stamp duty within the new portal. It marks a shift toward a fully integrated tax administration system in the country. This rule applies to both domestic and foreign taxpayers who earn income within the Indonesian jurisdiction.
The regulation requires all reports for the 2025 fiscal year to be submitted through the Coretax application. This means the 2026 reporting season is the first to use the unified digital interface exclusively. PER-11/PJ/2025 also clarifies the rules for requesting reductions in monthly installments for certain business types. The objective is to reduce the administrative gap between regional offices and the central authority.
The scope of this regulation covers every aspect of annual reporting for individuals and legal entities. It updates the required content for attachments to ensure they fit the new automated validation engine. Taxpayers must align their internal bookkeeping with these new data structures to avoid submission failures. Understanding this regulatory basis is the first step toward maintaining compliance in the digital era.
Individual taxpayers must now prepare their digital reports through the central Coretax dashboard. The previous e-Filing and e-Form channels on the DJP Online site are no longer active for the 2025 period. You must first activate your new account by linking your Taxpayer Identification Number to your national identity data. This integration allows the system to pull your data automatically from various government databases.
Standardized attachments now replace the old form-based reporting system. You will find specific digital schedules for reporting global income, luxury assets, and outstanding liabilities. Attachment 1 through 5 covers most requirements for employees and general individuals. These attachments are integrated directly into the web application for easier data entry.
The portal uses a guided interface to help you navigate the various sections of the report. You start by creating a concept and choosing the specific tax year you wish to report. The system then generates the necessary digital attachments based on your income profile. This automation reduces the risk of choosing the wrong format during your Income Tax Return in Indonesia preparation.
The new system removes the traditional form labels like 1770SS, 1770S, and 1770. These codes were used to distinguish between different levels of income and employment types. In the Coretax era, the interface adapts to your specific situation through a series of initial questions. This unified structure ensures that every taxpayer follows a consistent filing path.
The removal of these labels simplifies the terminology and reduces confusion for non-specialist users. The system analyzes your answers to determine which schedules and attachments are mandatory for your profile. This change ensures that your Income Tax Return in Indonesia is complete before you click the submit button. It prevents the common error of omitting global assets or domestic debts.
For individuals with business activities, additional schedules are available for reconciliation and loss carryforwards. The system automatically calculates your tax liability based on the data provided in these schedules. This change simplifies the user experience for digital nomads and freelancers in the region. By using a single gateway, the authorities can maintain a more comprehensive profile of each taxpayer.
Corporate entities, including every PT PMA in Indonesia, must comply with the new Coretax standards. The regulation makes online filing mandatory for all corporate income tax reports starting from the 2025 fiscal year. You cannot use the old offline software to generate your annual files for this period. The system now requires a direct connection to the national tax database for all submissions.
The corporate return includes a detailed header where you must define your accounting method. The default setting is accrual, but you can select cash if your company has previously notified the authorities. The main form provides a financial summary and the final tax computation for the year. This structure provides the tax office with a clear view of your corporate fiscal position.
Mandatory attachments for companies have been expanded to include more granular data points. Attachment 1 requires a full reconciliation between your accounting profit and your fiscal profit. Attachment 2 lists all shareholders and their respective ownership percentages to ensure transparency. Every PT PMA in Bali must ensure its bookkeeping records are categorized correctly to match these digital schedules.
Filing for a PT PMA in Bali follows a specific workflow within the Coretax portal. Your finance team should begin by preparing the balance sheet, income statement, and depreciation schedules. You must also have a monthly breakdown of turnover ready for entry. These documents form the basis of the data you will input into the digital application.
The authorized person for the company must log in to the portal using digital credentials. If you use a proxy, they must use the impersonate feature to select the correct corporate identity.
You then navigate to the concept menu to create a new return for the 2025 tax year. The system will prompt you to choose between a normal return or an amended return for your Integrated tax reporting.
After filling the mandatory attachments, you must generate a billing code if there is tax payable. The system allows you to pay directly through integrated banking channels before final submission. Once the payment is verified, you can transmit the report to the tax office. A success notification will appear in your digital inbox as proof of filing.
PER-11/PJ/2025 formally codifies the exemption rules for individuals with limited income. If your total annual earnings are below the non-taxable threshold, you are not required to file a report. This threshold is known locally as PTKP and varies based on your marital status and number of dependents. This rule specifically applies to those who only receive income from a single employer.
The exemption does not apply to individuals who run a private business or work as freelancers. Even if your net profit is low, the business activity requires you to maintain an active tax profile. This ensures that the government can track commercial activities across the digital economy. Expats who only earn a small salary from an overseas entity should check their specific residency status.
This change aligns with the goal of reducing administrative burdens for low-income residents in Bali. If you fall into this exempt category, you do not need to take any action in the Coretax portal. However, you should monitor your income levels annually to ensure you still qualify. Changes in family status or additional investment income can move you out of the exempt category.
Meet Hans, a 38-year-old software developer from Germany who lives in Pererenan. Hans moved to the region two years ago to work for a technology firm as an expatriate employee. In early 2026, Hans sat in his home office to submit his annual tax report. He planned to use his saved bookmarks from the previous year to complete the process quickly.
Hans quickly discovered that his previous login credentials were no longer sufficient for the 2025 reporting period. The old portal was closed for new entries as the deadline approached.
He tried to activate his new Coretax profile, but his digital identity was not correctly linked to his national ID number. Hans realized the technical error could lead to late filing penalties and issues with his work permit.
He visited Balivisa.co to resolve the data mismatch. The consultants identified that his identity records in the tax database were outdated. They helped Hans update his profile and link his credentials to the new portal within one afternoon. Hans was then able to complete his Integrated tax reporting through the concept menu in less than thirty minutes. He received his electronic receipt immediately, ensuring his residency status remained secure.
The deadlines for submitting your reports remain consistent with previous years. Individuals must complete their filing by 31 March if they follow the standard calendar year. Corporate taxpayers have until 30 April to submit their annual reports. You should start the process early to avoid server congestion during the final week of April.
Late filing results in a fixed administrative fine for both individuals and companies. Additionally, any underpaid tax is subject to monthly interest charges based on market rates. PER-11/PJ/2025 does not provide a reduction for these penalties during the system transition. The tax office uses a specific formula to determine the interest rate each month.
Failing to provide complete attachments can also lead to administrative queries. The Coretax system is designed to detect inconsistencies between your main form and the supporting schedules.
If your report is flagged, you may be required to file an amended return and pay additional fees. Maintaining accurate records throughout the year is the best way to avoid these compliance risks.
