About this calculator
Australia income tax with a tax-free allowance of $18,200 and a top marginal rate of 45%.

Frequently asked questions
What is the difference between effective and marginal rate?
Your marginal rate is the tax on your next dollar earned — the top band you reach. Your effective rate is total tax divided by total income, which is always lower because earlier income is taxed at lower bands.
Is this my exact tax bill?
No. It is a simplified estimate using the main income tax bands and standard allowance. It excludes credits, social security/National Insurance, local/state tax and special reliefs. Use it for guidance only.
