Frequently asked questions about Thai VAT and indirect tax

Does every Ko Samui business have to register for VAT?

No. VAT registration generally depends on taxable turnover and the nature of the business. A business carrying on VATable activities normally must register when annual turnover exceeds 1.8 million baht, although voluntary registration and special rules can apply.

When must a business register after reaching the VAT threshold?

A person liable for VAT generally applies for registration within 30 days after reaching the statutory threshold. The Revenue Department may require supporting documents showing the business, premises, activities, and responsible persons.

Can a foreign company providing services in Ko Samui owe Thai VAT?

It can. The result depends on where the service is performed, the customer, the contractual structure, and whether the foreign company carries on business in Thailand. Cross-border digital, management, booking, and technical services require a transaction-specific review.

What records should a hotel or restaurant keep?

Important records include sales reports, tax invoices, receipts, purchase invoices, payment evidence, booking-platform statements, payroll records, and import documents. Records should reconcile with monthly VAT returns and remain available for the statutory retention period.

How often are Thai VAT returns filed?

VAT returns are generally filed monthly using Form P.P.30, even where the business had no tax payable for the period. The normal deadline is the 15th day of the following month, with different electronic-filing deadlines sometimes applying.

Can a business claim input VAT on hotel renovations or equipment?
