What this estimate is doing
Starts with your total income
Employment income plus any other taxable income you add.
Subtracts deductions
This lowers the taxable income used for the estimate.
Calculates final tax
Income tax, Medicare levy and HELP are applied for the selected year.
Compares with tax withheld
That tells you whether you may get money back or still owe tax.
Before you estimate a refund
A tax return is more than just your salary.
The biggest gaps usually come from tax withheld, deductible expenses, offsets, second income, private health, HELP debt, and whether the salary figure you are using is only part of the story.
Tax withheld on your payslips
Work-related deductions
Bank interest or side income
Study debt or Medicare settings
What usually changes the refund
Tax withheld
Even a good salary estimate is not enough if the withholding across the year was unusual or incomplete.
Deductions
Work expenses, self-education costs and donations can change the final result if they are valid and properly recorded.
Extra income
Bank interest, side gigs and investment income often explain why a simple salary-only estimate feels wrong.
Offsets
Tax offsets can reduce the final bill, so a good refund estimate should let you include them.

Frequently asked questions
Can this estimate my refund today?
Yes, as a planning estimate. The result still depends on using the right tax withheld, deductions, offsets and income details.
Will this exactly match my lodged tax return?
Not always. It is designed for a clear estimate, not every edge case, private ruling, or tax return schedule.
