What I could do if I do not receive the “Business” or “Individual” eGUI tax invoice email?

Please avoid using free email domain (@yahoo, @gmail) to prevent email delivery issues. If you are using qualified email domain, please check the junk email box in case it is wrongly blocked.

The email sender is noreply@service.gwis.com.tw. To ensure the delivery success, you could add it to the email whitelist in advance.

If you still need help, please contact TI customer service center.
