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From 1 January 2005, the Tax File Number coding 00999999999 is no longer valid, the Australian Taxation Office will no longer accept certificate TFNs in any files from 2005.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 00bbbbbbbbb may be used if the student has not provided their TFN.  If the student has provided their TFN the actual number is to be reported.
ECAF (PO and VPO) only:
Only valid Tax File Numbers are reported on the ECAF.  00bbbbbbbbb will not be accepted.

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