🧠 Food for thought

Implications, context, and why it matters.

• Decree No. 117/2025/ND-CP makes e-commerce platforms withhold VAT and PIT from July 1, 2025, but guidance arrived so late that firms had under two months to adapt, while foreign operators often need 9–12 months 1.
• Platforms must collect seller names, taxpayer IDs, and residency to set rates 21. These include 1% VAT plus 0.5% PIT for resident individuals selling goods or 1% PIT for nonresidents, which can trigger cross-border data transfer rules that limit moving personal data out of Vietnam 21.
• Foreign platforms without a local entity face unclear rules for electronic withholding certificates, including whether certified domestic providers are needed 12. They still must file monthly returns as well as remit taxes 1. Mismatched start dates across the Tax Administration Law, the PIT law, and the VAT law add confusion 1.
• Indonesia’s 2025 SPP-TDLN regime makes foreign digital providers register as VAT collectors once they exceed IDR 600 million in annual transactions or 12,000 users, while Singapore requires GST above S$1 million revenue and Thailand applies 7% VAT with different thresholds 34.
• B2B SaaS founders can build middleware that automates seller classification, residency checks, and rate selection across Vietnam, Indonesia, and the Philippines 234. Vietnam uses platform-withheld VAT for resident individuals from 1% to 5% by transaction type, Indonesia sets 12% VAT, and the Philippines charges 12% on digital services 234. Vietnam also requires annual e-withholding documents, and Indonesia orders marketplaces to keep then submit detailed vendor records, which fuels demand for unified e-documentation APIs 23.
