Starting May 1, 2025, a 5% VAT will be applied to customers in Taiwan who have not provided their Taiwan VAT ID in their OpenAI account.
This VAT charge is a legally mandated tax on transactions for our products and services in Taiwan— it is not an additional charge for OpenAI services.
How to access and download your Taiwan eGUI?
If VAT is charged, an eGUI (electronic Government Uniform Invoice) will be sent to the email address associated with your OpenAI account from noreply@taxamo.com with the subject line: “Your eGUI [Invoice Number] from OpenAI”.
🔍 Tip: If you don’t see the email, please check your spam or junk folder.
If you need to update your email address, please refer to How to change your email address.
You can also retrieve your eGUI through the Taiwan Ministry of Finance’s e-Invoice Platform by using the “Citizen Audit” function to search for and download your eGUI.
