What you need to know about providing us with your TFN
We are authorised to collect your TFN under the Superannuation Industry (Supervision) Act. Where we collect your TFN, it will be kept confidential and only used for lawful purposes which may include:

finding or identifying your superannuation funds
calculating tax on any superannuation benefits paid
providing your TFN and other information to the Commissioner of Taxation
providing your TFN to your future superannuation fund trustee or Retirement Savings Account (RSA) provider if you are transferring your account. We will not pass on your TFN if you write to us and tell us not to.

We will not disclose your TFN to anyone else.

Providing your TFN is voluntary and declining to quote your TFN is not an offence. However, if you do not provide us your TFN, then:

you may pay more tax on your benefits than would otherwise be payable (you may get this back at the end of the financial year in your income tax assessment)
we may no longer be able to provide you with insurance cover, and your Asteron insurance policy may be cancelled.

As a result of recent changes to the law, the purposes for which we can use your TFN and the consequences of not providing it to us may change in the future.
