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From 1 January 2005, the Tax File Number coding 00999999999 is no longer valid, the Australian Taxation Office will no longer accept certificate TFNs in any files from 2005.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

Note: b represents one space. 00bbbbbbbbb represents two 0 (zero) characters followed by nine spaces.

For more information about terms used in these guidelines see the glossary.
