Further Filing Guidance Under The New Coretax System

April 10th, 2026|

Further Filing Guidance Under The New Coretax System

Further filing guidance under the Coretax system, as regulated by PER-3/PJ/2026, establishes clearer and more structured procedures for the submission, validation, and processing of tax returns (SPT).

Building on this framework, the regulation introduces a more stringent, system-driven approach to compliance by prioritizing electronic filing and reinforcing validation controls. An SPT is considered officially filed only after it has successfully passed system validation and a Bukti Penerimaan Elektronik (BPE) has been issued, replacing earlier practices in which proof of submission alone could suffice. At the same time, taxpayer data, including NPWP and reported information, is subject to enhanced real-time validation, increasing the likelihood of rejection in cases of discrepancies. As a result, the compliance focus shifts from merely meeting deadlines to ensuring the accuracy and acceptability of submissions, requiring stronger data integrity and system readiness.

In addition, the regulation narrows the availability of filing deadline extensions by limiting them to specific circumstances, such as ongoing financial statement preparation or audit, or delays in receiving withholding tax slips. SPTs that fail to meet the prescribed requirements may be treated as not submitted and subject to administrative sanctions. Overall, PER-3/PJ/2026—comprising five chapters and 25 articles—serves as a refinement of the Coretax implementation by the Directorate General of Taxes (DJP), replacing certain provisions under PER-11/PJ/2025 and aiming to enhance accuracy, consistency, and administrative efficiency in tax reporting.

Here is a summary of the PER-3/PJ/2026:

Indonesia Introduces Global Minimum Tax Framework Effective January 2025

January 21st, 2025|

Indonesia Introduces Global Minimum Tax Framework Effective January 2025

Implementation of Pillar Two Global Minimum Tax Effective from 1 January 2025

Indonesia has officially adopted the Global Minimum Tax (GMT) under the Minister of Finance Regulation Number 136 of 2024 (PMK-136), effective from 1 January 2025. This regulation aligns with the OECD’s Pillar Two framework on GMT.

The Global Minimum Tax applies to multinational enterprises (MNEs) with an annual turnover of at least EUR 750 million. Its primary objective is to ensure that corporate income earned within a jurisdiction is taxed at a minimum effective rate of 15%, achieved through the application of a “top-up tax.”

Implications for Indonesia

Under PMK-136, the affected entities include:

  1. Indonesia-based MNEs: Indonesian-headquartered groups with subsidiaries or operations abroad.
  2. Indonesia-based subsidiaries of foreign MNEs.

Key Tax Mechanisms

The regulation outlines three main top-up tax mechanisms in line with the OECD Model Rules:

  • Income Inclusion Rules (IIR)
  • Domestic Minimum Top-up Tax (DMTT)
  • Undertaxed Payment Rule (UTPR)

Additionally, the regulation specifies a De Minimis Rule applicable to jurisdictions where:

  • The average CE’s GloBE revenue is less than EUR 10 million, and
  • The average CE’s GloBE net income is less than EUR 1 million, or a net loss occurs.

Filling and Compliance Requirements

The filing obligations for Ultimate Parent Entities (UPEs) and Constituent Entities (CEs) are summarized below:

Filing Obligation Description Responsible Party
GloBE Information Return A detailed report of global income and tax information for the MNE group. UPE
Notification Declaration of the entity’s status within the group for compliance purposes. CE
GloBE Income Tax Return Annual filing detailing the effective tax rate and top-up tax calculations. UPE
DMTT Income Tax Return Report for domestic top-up tax obligations under the DMTT mechanism. CE
UTPR Income Tax Return Filing for undertaxed payments addressed by the UTPR mechanism. CE

The afore-mentioned filings shall be submitted at the latest 15 months to the Director General of Tax (DGT) upon the fiscal year-end. The grace period of three months is however granted for initial implementation of PMK-136.

Penalties for Non-Compliance

Late submission or payment of top-up taxes will incur administrative penalties as stipulated by prevailing domestic regulations.
