Thailand VAT Rates 2026

Thailand (ประเทศไทย (Prathet Thai)) levies Value Added Tax under the name เลขประจำตัวผู้เสียภาษี (Tax Identification Number / TIN). The standard rate is 7%, applied to most goods and services. Thailand applies a single flat rate with no reduced rates.

Access rates via API

The TaxID API returns current VAT rates for all 27 EU countries. Use the /api/v1/rates/TH endpoint to get Thailand rates programmatically. Responses are cached for 24 hours.

curl http://localhost:3000/api/v1/rates/TH
# No authentication required for rate lookups

# Response:
# { "country_code": "TH", "standard_rate": 7,
#   "reduced_rates": [], "currency": "THB" }

Applying the correct rate in code

For B2B intra-EU sales, validate the customer's VAT number first. A valid registration means reverse charge applies — you charge 0% and the customer self-accounts. For B2C, charge the Thailand standard rate.

// 1. Validate the customer's Thailand VAT number
const vatCheck = await fetch(
  'http://localhost:3000/api/v1/validate/TH/CUSTOMER_VAT',
  { headers: { Authorization: 'Bearer YOUR_API_KEY' } }
).then(r => r.json());

// 2. Fetch current Thailand VAT rates (no auth required)
const rates = await fetch('http://localhost:3000/api/v1/rates/TH').then(r => r.json());
// → { standard_rate: 7, reduced_rates: [] }

// 3. Apply the correct VAT treatment
if (vatCheck.valid) {
  // B2B intra-EU: reverse charge — you invoice 0%, customer self-accounts
  applyRate(0, 'reverse_charge');
} else {
  // B2C: charge the Thailand standard rate
  applyRate(rates.standard_rate, 'standard');
}

About Thailand VAT

Thailand's VAT rate is currently 7% (temporarily reduced from the statutory 10% rate, in effect since 1997 and renewed periodically). The 13-digit TIN doubles as both corporate and individual identification. Thailand is a growing regional hub for B2B SaaS in Southeast Asia.

The Thailand เลขประจำตัวผู้เสียภาษี is administered by the national tax authority and validated through the EU VIES system. Before applying any VAT rate or zero-rate exemption to a Thailand business customer, validate their VAT registration number first.
