- 2.Deduct Pre-Tax Items: Subtract salary sacrifice to super and eligible work deductions to find taxable income.
- 3.Apply ATO Tax Brackets: Calculate marginal income tax for FY 2026–27 and apply LITO if eligible.
- 4.Medicare & HELP: Subtract the 2% Medicare levy and marginal HELP/HECS repayment to arrive at net take-home pay.
- 5.Employer Super (12%): Calculated separately on Ordinary Time Earnings and paid to your super fund.
There is no flat "bonus tax rate" in Australia — a $5,000 bonus on a $95,000 salary is taxed at 30% + 2% Medicare, leaving about $3,400. Payslip withholding on the bonus pay run is higher because PAYG annualises that run.
How Bonuses Are Taxed (No Special Rate)
A bonus is ordinary assessable income added to your salary for the financial year. Its cost is your marginal rate — the tax on the top dollars of income — so a bonus that lifts you across $135,000 pays 37% + 2% Medicare on the portion above the threshold.
Why Payslip Withholding Looks Bigger on Bonus Week
PAYG withholding on a pay run containing a bonus uses the ATO Schedule 5 method: it spreads the bonus across the year or withholds at the marginal rate of that annualised run. Over-withholding is refunded at tax-return time.
