Do I need to register for VAT in Thailand?
Thailand charges 7% VAT on B2C digital services supplied by foreign electronic service providers under its VAT on Electronic Service (VES) regime, in force since 1 September 2021. Registration is required once annual supplies to Thai non-VAT-registrants exceed THB 1.8M.
B2C digital services (SaaS, streaming, online ads, e-learning, downloads): register for VES once annual supplies to Thai consumers exceed THB 1.8M. Tax rate is 7% on the supply value.
B2B digital services to a VAT-registered Thai buyer: outside VES. The Thai buyer self-assesses VAT under the reverse-charge mechanism.
VAT-registered status check: verify the buyer's Thai VAT number; without one, the sale is treated as B2C and you owe 7% VAT.
VES registration is digital-only. No Thai-resident representative is required.
How to register
VES registration runs through the RD SVE (Simplified VAT for E-Service) portal. The portal supports English-language applications and was designed for cross-border electronic-service providers.
What you'll need: US tax ID (EIN), business legal name, evidence of crossing THB 1.8M, expected Thai turnover, bank account details (any currency).
Typical timeline: Approximately 30 days from a complete application to RD approval and VES registration number issuance.
Cost: Registration is free. No fiscal representative or bank guarantee required.
Filing and deadlines
VES returns are filed monthly through the SVE portal, due by the 23rd of the month following the tax period. There is no OSS overlap.
Local Thailand filing frequency: Monthly.
Return due: 15th of following month.
Payment due: Same as return.

Common mistakes US SaaS makes in Thailand
Counting B2B (VAT-registered) supplies in the threshold. Only supplies to non-VAT-registrants count toward THB 1.8M. Get the buyer's Thai VAT number to confirm registration.
Missing the 23rd-of-month filing deadline. Monthly returns means twelve filings per year, easy to miss when scaling up.
Confusing the 7% rate with Thailand's 10% statutory rate. The standard rate is statutorily 10% but reduced to 7% by ongoing royal decree. VES applies the prevailing 7%.
Treating goods sales as VES. VES covers digital services only. Goods follow regular import VAT rules.
Trusting Stripe Tax to handle VES. Stripe collects but you remain the supplier of record. VES registration and remittance are still your obligations.
