VAT and Customs Duties in Thailand

Value Added Tax (VAT) and customs duties significantly impact business costs and cash flow. Understanding registration requirements, applicable rates, and compliance obligations helps businesses manage these indirect taxes effectively.

Our Tax Department advises on VAT registration, filing, and audit defense. We also assist with customs classification, valuation disputes, and applications for duty privileges under BOI promotion or free trade agreements.

Thailand's VAT rate is currently 7% (reduced from the statutory 10%). Businesses with annual revenue exceeding THB 1.8 million must register for VAT. Exporters benefit from zero-rating, can claim refunds of input VAT paid on business purchases.

Customs duties vary by product classification and can significantly impact import costs. We advise on tariff classification to ensure accurate duty assessment and identify opportunities for duty reduction through preferential trade agreements or BOI exemptions.

Frequently Asked Questions

When are VAT returns due? VAT returns must be filed monthly by the 15th of the following month (23rd for electronic filing).

Can input VAT always be claimed? No. Input VAT on certain expenses such as entertainment, vehicles for personal use, and expenses without proper tax invoices cannot be claimed as credits.

What changed with the de minimis threshold in 2026? Effective January 1, 2026, Thailand eliminated the THB 1,500 de minimis exemption for import duties on low-value goods, meaning all imported goods are now subject to duty and VAT assessment.
