VAT in Thailand: Registration, Rates & Filing (2026)

Value Added Tax (VAT) is one of the most common compliance points for companies in Thailand. Here's what you need to know in 2026.

The basics

• Rate: 7% (standard).
• Registration threshold: mandatory once annual revenue exceeds THB 1.8 million; voluntary below that.
• Filing: monthly return (PP30), due by the 15th of the following month.

Should you register voluntarily?

Registering below the threshold lets you reclaim input VAT on purchases — useful for businesses with significant expenses or B2B clients. We advise on the right call for your model.
