Coding notes

From 1 January 2005, the Tax File Number coding 00999999999 is no longer valid, the Australian Taxation Office will no longer accept certificate TFNs in any files from 2005.

A TFN must be provided for every student with a HELP debt. In circumstances where a student has no HELP debt for any unit of study in the reporting period and is therefore not required to provide a TFN, a value of all spaces may be used if the student has not provided their TFN.

Please refer to the Glossary for further information about terminology used in this document.
