Tax

Tax file number declaration

At the commencement of employment at UON, all employees are required to complete a Tax File Number (TFN) Declaration Form.  If this form is not received, 49% of your pay will be withheld.

The forms are available from

  • Human Resource Services at the Chancellery, Callaghan Campus
  • many local work areas
  • newsagents

Please note: forms dated prior to 2014 (at the bottom of page 1) are no longer accepted.

If you have applied to the Australian Taxation Office (ATO) for a TFN you have 28 days to provide the TFN on a new form.  Failure to complete another form with your TFN included within 28 days will result in 49% of your pay being withheld for tax.

Tax free threshold

The tax free threshold is currently $18,200 per annum. 

If you claim the tax free threshold:  Tax will be deducted once you earn $714.00 a fortnight or greater ($714 x 26 fortnights/year = $18,564 per annum). You may earn less over the whole year, however we must calculate tax each fortnight you receive earnings. 

If you do not claim the tax free threshold: Tax will be deducted once your earn $6.00 a fortnight or greater.

Overseas residents

Overseas residents will need to check the instructions on the form to ascertain if you meet the criteria of an Australian resident for tax purposes.

HELP debt

HELP repayments are deducted along with tax once your earnings exceed the government thresholds.

If you have a HELP debt, the following deductions will apply:

  • If you claim the tax free threshold, the HELP debt will be deducted when you earn $2,080.00 or more per fortnight.
  • If you do not claim the tax free threshold, the HELP debt will be deducted when you earn $1,380.00 or more per fortnight

HELP deductions do not automatically go to the ATO but are calculated by the Australian Taxation Office after you lodge your tax return.  Your payslip will show the code HECS which identifies the HELP choice you made on the TFN form.
