Understanding bonus taxs in Australia
A bonus is added to your income and taxed at your marginal tax rate, so a bonus can feel heavily taxed if it pushes part of your income into a higher bracket. There is no separate 'bonus tax rate' in Australia.
Employers often withhold tax on a bonus at a higher flat rate up front, so your pay may look heavily taxed, but you reconcile it at tax time and get any excess back. This estimate ignores the Medicare levy and HELP/HECS repayments.
Frequently asked questions
How much tax do I pay on a bonus in Australia?
A bonus is taxed at your marginal rate, the same as ordinary income. It is not a special 'bonus tax', though your employer may withhold more up front, which is reconciled at tax time.
Why was so much tax taken out of my bonus?
Employers often withhold tax on bonuses at a higher flat rate to avoid under-withholding. If too much was taken, you get the excess back when you lodge your tax return.
