Indonesia's PMK 112 implementation notice matters because treaty relief is being pushed into a more standardised DGT-form and Coretax workflow

On 9 January 2026, DJP said treaty application by nonresident taxpayers should use the PMK-112/2025 Formulir DGT format, while legacy forms remain usable for their stated period and submissions continue through Coretax.

What the 9 January 2026 notice actually did

DJP's implementation announcement for PMK 112/2025 made the treaty-procedure consequences concrete. The notice said nonresident taxpayers should use the Formulir DGT format under PMK-112/2025, explained that older forms issued under the prior rules remain valid for their stated period, and confirmed that submission and uploading continue through the Coretax menu for SKD WPLN. That is operational guidance, not just regulatory background noise.

Why this matters for cross-border withholding work

Treaty relief often sounds abstract until documentation breaks. The point of this announcement is that Indonesia is standardising how treaty benefit claims and residence documentation are supposed to move through the system. That matters to foreign recipients, withholding agents and advisers because the practical route now matters just as much as the underlying treaty article.

Who should react to it

This update matters most to nonresident taxpayers claiming treaty relief, Indonesian withholding agents, and cross-border advisers who rely on established documentation habits. The safe move is to refresh the treaty-claim checklist against PMK 112/2025 and the Coretax filing pathway instead of assuming the old procedure will simply carry forward unchanged.
