Tax file numbers

Last updated 29 August 2017

We use tax file numbers (TFNs) to match the details on a member's tax return with contributions reported on the Superannuation member contributions statement. This information determines whether surcharge needs to be paid.

If a member has provided their TFN, providers should report this TFN to us with the member's surcharge obligations. If a member gives their TFN to a super provider, it means they are allowing the provider to use the TFN for surcharge purposes.

If we are unable to match a taxpayer to the surchargeable contributions reported by the provider because a correct TFN was not provided, these contributions may be subject to the maximum rate of surcharge.
