The Threshold Has Crossed: Regime decision at the PPh Final boundary, audit-notice response within the legal window, and new business unit registration structured before the wrong default takes effect.

A six-question diagnostic intake routes the reader to the right framework based on which trigger has fired.

Threshold Crossing Decision Map. Run when revenue is approaching or has crossed the PPh Final 0.5 percent threshold mid-year. Models the corporate-tax regime alternatives, computes the cumulative tax impact across the rest of the year, and produces a structured decision before the threshold-crossing month closes. Two worked examples: a CV distributor approaching the threshold, and a manufacturing PT crossing the threshold mid-year with a high-investment cost base where the general regime math changes materially.

Audit Exposure Response Framework. Run within hours of receiving a DJP audit notice — SP2DK or SP2. Reconstructs the exposure across the audit period, sequences the documentary trail, and produces a structured response within the legal window. Two worked examples: a garment contractor facing a first audit on PPh 21 and PPh 23 withholding, and a manufacturing PT with scattered documentation across multiple business units.

New Business Unit Registration Choice. Run when a new business unit, division, or related entity is being launched and the question is what registration structure — PKP, separate NPWP, group structure — actually fits the operation. Two worked examples: a CV food processing business adding an online channel, and a manufacturing PT adding a related distribution entity.

Each tool carries a self-scoring rubric, a quick decision tree, and tier adaptations for single-owner shops, mid-tier businesses, and pre-IPO operations. The response plan at the back sequences the three frameworks across the first 48 hours, the first week, and the first month after a trigger fires.

This companion draws on operator experience running businesses in Indonesia, where PPh Final thresholds, DJP audit procedures, and registration structures follow Indonesian tax law. Examples reflect that context. The decision-making disciplines carry across to small and mid-sized businesses in other emerging markets facing equivalent threshold and registration decisions; local tax interpretation always requires a qualified professional.

What this companion does NOT do

Replace Tax Optimization for SMEs (Operator Playbooks 15).

Replace a tax consultant or accountant. The tools surface decision logic; tax interpretation requires qualified professional judgment.

Substitute for the weekly-rhythm or quarterly-review companions.
