Applying the correct rate in code

For B2B sales to Thailand, validate the customer's เลขประจำตัวผู้เสียภาษี first — a verified registration is typically required for correct invoicing and zero-rated exports. For B2C, charge the Thailand VAT rate where registration rules require it.

// 1. Validate the customer's Thailand tax ID
const check = await fetch(
  'https://www.taxid.dev/api/v1/validate/TH/CUSTOMER_TAX_ID',
  { headers: { Authorization: 'Bearer YOUR_API_KEY' } }
).then(r => r.json());

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

// 3. Apply the correct treatment for your supply
applyRate(check.valid && isB2BExport ? 0 : rates.standard_rate);

About Thailand VAT

Thailand's VAT has a statutory rate of 10%, but a "temporary" reduction to 7% — first granted during the 1997 Asian financial crisis — has been renewed by royal decree every year for nearly three decades, making the 7% rate one of tax policy's most durable temporary measures. Foreign e-service providers above THB 1.8 million in Thai B2C sales must register under the VES regime introduced in 2021. Exports and international transport are zero-rated rather than exempt, preserving input credits.

VAT in Thailand is administered by the Revenue Department (กรมสรรพากร). Before applying any zero-rate or exemption to a Thailand business customer, validate their registration first.
