VAT taxable period is a calendar month. VAT return therefore must be filed on a monthly basis. VAT return (Form VAT 30) together with tax payment, if any, must be submitted to Area Revenue Branch Office within 15 days of the following month. If taxpayer has more than one place of business, each place of business must file the return and make a payment separately unless there is an approval from the Director-General of the Revenue Department. Services utilized in Thailand supplied by service providers in other countries are also subject to VAT in Thailand. In such a case, service recipient in Thailand is obliged to file VAT return (Form VAT 36) and pay tax, if any, on behalf of the service providers.
