How can businesses ensure compliance with the new tax regulations under CTAS?
The Directorate General of Taxes (DJP) is undergoing a major digital transformation with the introduction of the Core Tax Administration System (CTAS). This long-awaited system eliminates inefficiencies, reduces system downtimes, and improves data integration across Indonesia’s tax administration.
Originally scheduled for launch in July 2024, the government postponed full implementation to early 2025 to ensure technical readiness and a smooth transition.
As Indonesia moves towards a more integrated and user-friendly tax system, businesses and taxpayers must prepare for changes impacting tax registration, filing, payments, and compliance monitoring.
Key Takeaways
- CTAS will modernize Indonesia’s tax system – integrating NPWP with NIK and streamlining 21 tax administration processes.
- New features like Taxpayer Portals, TAM, and centralized tax filing will improve transparency and compliance.
- Businesses must adapt to the new tax registration, payment, and reporting requirements.
Legal Basis and Objectives of CTAS
The implementation of CTAS is based on:
Presidential Regulation No. 40 of 2018 – Focuses on tax administration reform. Minister of Finance Decree No. 483 of 2020 – Reinforces the initiative by setting guidelines for system modernization.
Key objectives of CTAS: Create a transparent and integrated tax system that simplifies taxpayer interactions with DJP. Enhance data integration between tax authorities and relevant institutions. Increase taxpayer compliance through real-time monitoring and automation. Improve efficiency in tax filing, payment processing, and compliance management.
Key Transformations in Indonesia’s Tax Administration
1. NPWP-NIK Integration & Taxpayer Data Validation
- The first phase of CTAS implementation involves integrating NPWP (Taxpayer Identification Number) with NIK (National Identification Number).
- Taxpayers will also be required to validate email addresses and phone numbers, which will serve as official communication channels for tax obligations.
2. Streamlining 21 Core Business Processes
CTAS is more than just a system upgrade—it represents a fundamental transformation of 21 tax administration processes, including:
- Taxpayer Registration & Compliance Monitoring
- Tax Collection & Payment Processing
- Data Integration & Risk Management
- Audit, Investigation, & Appeals Handling
Direct Impact of CTAS on Taxpayers
1. Simplified and Integrated Taxpayer Registration
- No more regional tax office restrictions—taxpayers can register and manage their tax data online through a dedicated Taxpayer Portal.
- Elimination of Branch NPWP – Businesses will use the Business Activity Identification Number (NITKU) instead.
2. Flexible Tax Payments with a Single Billing Code
- CTAS introduces a single billing system, allowing taxpayers to pay multiple taxes in one transaction.
- The new pre-deposit tax feature enables taxpayers to allocate pre-deposited funds for tax payments when needed.
3. Transparency Through Taxpayer Account Management (TAM)
Taxpayers will have real-time access to their tax records, including:
- Transaction history & outstanding liabilities
- Tax audit & dispute resolution status
- Access to SME tax exemptions & other incentives
4. Centralized & Efficient Tax Filing
CTAS consolidates multiple tax reporting platforms (e-Filing, e-SPT, e-Bupot, etc.) into a single unified system, making it easier for both individuals and businesses to comply with tax regulations.
5. Improved Tax Services & User-Friendly Features
- Employers’ PPh 21 reports will be automatically recorded in employees’ tax accounts, making annual filing seamless.
- Individual tax returns will adopt a standardized format, simplifying the submission process.
