A company registered in the VAT system that wants to issue a tax invoice in a foreign currency needs to get a permission from the Director General of the Revenue Department to do so.

We have a client who receives an order from an overseas buyer for goods to be delivered to the buyer’s customer in Thailand. That is considered a domestic sale because the goods never leave Thailand. Therefore, the company cannot issue tax invoices in a foreign currency.

However, if the company has issued a correct tax invoice as stipulated by law, they can add the foreign currency amounts to that tax invoice in addition to the Thai Baht amounts.
