Tickets already include entertainment tax and act as an invoice, therefore tickets are exempt from issuing invoices. An e-invoice will be issued and sent to you via email for any system service fees. The Email as shown in your Member Profile will be used for invoice issuing when you purchase tickets. To learn more about the e-invoice system and how to use these invoices please visit the Ministry of Finance's E-Invoice Platform website.
