Intelligence Brief: Starting July 14, 2025, Indonesia’s Ministry of Finance activated PMK 37/2025: major marketplaces can be appointed as Article 22 withholding agents, collecting a 0.5% income tax on certain seller revenues at the point of transaction. This is not a “new tax” as much as a distribution upgrade—moving tax collection from fragmented SMEs to platform-level rails.
01. Appointment Trigger: “Big Platforms Only”
A marketplace is appointed when it crosses scale thresholds—meaning the compliance burden lands on the largest platforms, not on every small online shop.
Transaction Threshold
IDR 600M / yr
Or ≥ IDR 50M in a single month (transaction value on the platform).
Traffic Threshold
12,000 users
Or ≥ 1,000 users in a single month (traffic/engagement proxy for scale).
02. Who Pays, Who’s Exempt
The withholding targets qualifying seller income. Micro sellers with very small turnover remain protected—this is designed to hit the “missing middle” rather than street-level commerce.
| Seller Segment | Treatment | Notes |
|---|---|---|
| UMKM micro | Exempt | Exemption applies under a turnover threshold (policy intent: avoid hurting smallest sellers). |
| Mainstream online sellers | 0.5% Article 22 | Withheld by marketplace at point of transaction (gross basis). |
| Excluded categories | Not withheld | Certain verticals can be excluded (implementation details vary by appointment and guidance). |
03. Startup Implication: Platform Rails Become “Tax Rails”
Once marketplaces become tax collectors, everything upstream changes: onboarding, KYC, seller verification, refunds, and settlement logic become part of a tax-grade ledger.

Analyst Outlook
"PMK 37/2025 is a structural move: tax collection shifts from millions of sellers to a handful of platforms. The winners will be marketplaces and merchant tools that can operate at audit-grade precision—ID verification, clean settlement logs, and frictionless reconciliation. Expect a wave of ‘compliance-native’ commerce tooling in 2026."
