Under the Superannuation Industry (Supervision) Act 1993, we are authorised to collect your TFN. It's not compulsory to tell us your TFN, nor is it an offence not to do so. However, if you don't tell us your TFN, your before-tax contributions and withdrawals are taxed at a higher rate, we can't accept after-tax contributions from you, and our Super Search Party will not be able to help you find your existing and lost super.
