Where can I find my Taiwan GUI (Government Unified Invoice)?
Whenever you make a purchase through Google Play in Taiwan (regardless from Google or developer), Google is required by law to charge 5% Value Added Tax and send you a standardized electronic invoice document called a Government Uniform Invoice (GUI or eGUI). This requirement is specified in the “Time Limit for Issuing Sales Documentary Evidence” section of Taiwan’s “Value-added and Non-value-added Business Tax Act.”
The content of the invoice is regulated and standardized for all businesses.
After you make a purchase from a Google account, we'll email your GUI invoice to the email address associated with said account.
Additionally, you can view and download the GUI from your product account.
How does the Taiwan GUI Lottery work?
Each eGUI we send you includes a pre-assigned serial number that you can use to participate in the GUI lottery.
To participate, use the “Claiming Reward App” and the “E-Invoice platform” from the Taiwan Ministry of Finance to register your email address and sign up for lottery result notifications.
What if I cancel my purchase?
If you cancel your purchase and your refund is approved, your GUI won’t be valid nor eligible for the lottery. (You may, however, continue to see a link to the GUI in your product account.)
We’ll issue you a sales allowance certificate (SAC) for the refunded amount. You can view and download SACs from your product account.
