The Thai tax office recently enacted a law that allows VAT-liable parties to send electronic invoices and receipts to their customers on a voluntary basis. This applies to the sale of goods or the provision of services. This eliminates the need to print and deliver these documents in paper form.
The process to be allowed to issue electronic invoices and receipts involves the application by the taxable party. In order to do so, the applying party must meet certain criteria and be a limited liability company or joint stock company with a fully paid-up registered capital of at least 10. million baht, or a government agency. There must also be a track record of performing business activities over a period of time and a sound internal control system.
Once approved by the tax office, the prescribed rules and conditions for the preparation and storage of electronic tax invoices and receipts must be followed. These rules also include certain controls at the IT level regarding the security of the data.
Furthermore, e-invoices and e-receipts must contain two digital signatures created by the prescribed means and supported by a certificate and the signatory’s certificate number. This number is issued by the approved certification body of the tax authority.
