Thailand VAT Rates 2026

Thailand (ประเทศไทย (Prathet Thai)) levies Value Added Tax as ภาษีมูลค่าเพิ่ม (VAT). The standard rate is 7%, applied to most goods and services. Thailand applies a single flat rate with no reduced rates.

Thailand has no public registry we can query in real time, so a number cannot be confirmed as active from outside. The Thai VAT number checker still checks it against the national format, which catches transcription errors before they reach your accounting system.

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.
