What's your tax file number?
You can find your TFN on statements you've received from the Tax Office, your super fund, your work payment summary, or alternatively you can contact the Tax Office on 13 28 61 for help finding it. A quick search of your emails might find it too!
By providing your TFN you give Future Super permission to use your TFN for superannuation purposes. This includes creating your account, actioning any rollovers which you request, or using the Australian Taxation Office SuperMatch service.
