How is pro-rata salary calculated?
Pro-rata salary is calculated by multiplying the full-time annual salary by your work fraction. For example, a $80,000 full-time role worked 3 days per week (0.6 FTE) gives a pro-rata salary of $48,000. Tax is then calculated on the reduced amount.
Do part-time workers pay less tax?
Yes — because your gross income is lower, you fall into lower tax brackets and pay proportionally less tax. Your employer also pays less super guarantee since it's 12% of your reduced salary. This calculator shows exactly how much less.
Does pro-rata affect my HELP repayment?
Potentially. HELP repayments are based on your total income. If going part-time drops your income below the repayment threshold, you may not need to make compulsory repayments that year.
