Progressive tax in plain terms
The first slice of taxable income is treated differently from later slices. Moving into a higher bracket does not make earlier income taxed at that higher rate.
Brackets explain marginal tax
Your marginal rate is the rate that applies to your next dollar of income before other settings are considered.
Take-home pay needs more than brackets
Medicare levy, HELP repayments, deductions, residency and super treatment can all affect the final estimate.
Common questions
Does entering a higher bracket reduce my pay?
No. Extra income can be taxed at a higher rate, but earning more gross income generally increases take-home pay.
Are tax brackets the same every year?
Not always. Use the financial year that matches the income you are estimating.
