Australia Bonus Calculator

About This Calculator

This Australia Bonus Calculator estimates how much of a one-off bonus or commission you will take home after federal tax and the Medicare levy. Bonuses in Australia are taxed as ordinary income under PAYG—they are added to your total taxable income for the year. This calculator treats the bonus as standalone income, so it gives a simplified estimate. If you receive a bonus alongside a regular salary, the effective tax rate may differ because of cumulative PAYG withholding. Use this tool to get a quick idea of your bonus after tax.

How Is Bonus Tax Calculated in Australia?

Bonuses are taxed as part of your assessable income under Australia's Pay As You Go (PAYG) system. Federal income tax applies using the same progressive brackets as salary: 0% on the first $18,200, then 16%, 30%, 37%, and 45% on higher bands. The Medicare levy (2%) also applies to bonus income.

This calculator treats your bonus as standalone income. In reality, if you have a main job, your employer typically withholds tax on the bonus based on your cumulative income for the year. A bonus paid early in the financial year may attract less tax than one paid later, when more of your annual income has already been earned. The calculator gives a reasonable estimate for most situations. For exact withholding, refer to ATO guidelines or speak to a tax professional.
