Where you have purchased a prepaid Kogan Mobile service or recharged your service with a credit card from koganmobile.com.au, a tax invoice will not be issued. This is because you are effectively purchasing a voucher, and vouchers do not attract GST.
If you have redeemed a Kogan Mobile Prepaid Voucher purchased from Kogan.com, GST does not apply and you will not be issued a tax invoice. If you require proof of purchase, please refer to the Kogan.com order confirmation email sent you to you when you purchased your Kogan Mobile Prepaid Voucher.
