The Directorate General of Taxes (DJP) has officially introduced a major update to its digital ecosystem with the launch of CoreTax Mobile, integrated within the M-Pajak application. This initiative marks a significant milestone in Indonesia's tax administration reform, aiming to simplify compliance and increase accessibility for individual taxpayers across the country.

Streamlining compliance via mobile devices
The introduction of CoreTax Mobile is designed to provide a more intuitive and flexible experience. Historically, reporting annual tax returns (SPT) required access to a desktop browser or a physical visit to a tax office. With this launch, the DJP is bringing tax services directly to the palms of taxpayers’ hands.
Inge Diana Rismawanti, Director of Counselling, Services and Public Relations at the DJP, stated that the mobile version of the CoreTax system is specifically developed to cater to the modern, mobile-first lifestyle of Indonesian citizens.

Who can use CoreTax Mobile?
In its current phase, the mobile reporting feature is optimised for individual taxpayers (Wajib Pajak Orang Pribadi) who meet specific criteria:

1. Single source of income: Employees who receive income from only one employer
2. Normal status: Reporting for the current tax year (not amendments/pembetulan)
3. Nihil status: Tax returns where the tax liability has been fully settled through withholding, resulting in zero balance due.

Key features and user guide
The M-Pajak application now serves as a mobile gateway to the broader CoreTax system. Users can perform several critical functions, including:

• Concept creation: Drafting SPT forms directly on the app
• Data validation: Real-time checks to ensure the information provided is ‘complete, correct and clear'
• Electronic filing: Instant submission of the annual return.

Step-by-step reporting:

1. Download: Install the M-Pajak app from the official Google Play Store (Android) or Apple App Store (iOS)
2. Login: Use your registered CoreTax DJP credentials
3. Create concept: Select the option to create a new SPT concept
4. Fill & submit: Follow the prompts to input data and submit the return.

Security and vigilance
As tax services move to mobile platforms, the DJP has issued a strong advisory regarding cybersecurity. Taxpayers are urged to:

• Only use official links: Download the app exclusively from official stores
• Avoid phishing: Do not click on suspicious links or download ‘.apk’ files sent via WhatsApp or email claiming to be from the tax office
• Official channels: For assistance, always refer to the official Kring Pajak 1500200 or visit the nearest Tax Service Office (KPP).
