How this calculator works
Your marginal rate is the rate on the bracket your last dollar falls into. The calculator also measures tax on an extra $1,000 so offsets and the Medicare levy are included.
Worth knowing
Your marginal rate is what matters for deductions: a $1,000 deduction saves $1,000 × your marginal rate, not your average rate.

Questions
- Are these results exact?
- They are estimates based on standard resident rates. Your actual tax depends on your full circumstances, offsets and any private health insurance position. The ATO’s own tools or a registered tax agent give a definitive answer.
- Do the calculators work for non-residents?
- No. Non-residents have different rates, no tax-free threshold and no Medicare levy. These calculators assume you are an Australian resident for tax purposes.
- When do tax rates change?
- Rates usually change on 1 July, the start of the Australian financial year. Check the ATO website each July for the current figures.
This calculator gives general estimates using published Australian rates and formulas. It doesn’t consider your personal circumstances. Check current figures with the ATO, your state government or a qualified professional before making decisions. See our disclaimer.
