Tax on a $8,000 Bonus in Australia (2025-26)
A $8,000 bonus is not taxed at a special final rate. These examples compare its simplified annual tax effect with ATO Schedule 5 Method A withholding on a fortnightly pay cycle.
Quick answer
A $8,000 bonus forms part of annual taxable income. Schedule 5 withholding is a payroll prepayment, while the annual tax effect depends on where the bonus falls across the brackets, LITO and Medicare levy settings.
| Base salary | Actual tax on bonus | PAYG withholding | Withholding difference | Effective bonus tax rate |
|---|---|---|---|---|
| $70,000 salary | $2,560 | $2,548 | −$12 | 32.0% |
| $100,000 salary | $2,560 | $2,548 | −$12 | 32.0% |
| $150,000 salary | $3,120 | $3,120 | +$0 | 39.0% |
A positive difference means Method A withholding is above this simplified annual estimate; a negative difference indicates a possible shortfall. Neither result alone predicts your final refund or bill.
This example uses a fortnightly pay cycle, assumes the tax-free threshold is claimed and excludes HELP, MLS, family Medicare adjustments, other offsets, deductions and other income.
Bonuses between $5,000 and $15,000 are common for annual performance bonuses and retention payments. The bonus may cross an income-tax bracket, change the Medicare levy or affect HELP and other income-tested amounts, so compare the complete annual position as well as the payslip withholding.
How Schedule 5 treats the bonus
For a whole-year or undefined-period bonus, Method A divides the bonus across 52, 26 or 12 pay periods, compares ordinary withholding, and multiplies the difference back up. Method B(ii) can use average year-to-date earnings and prior additional payments.
Salary sacrifice to super is effective here
Salary sacrifice can change the income-tax treatment where the arrangement is valid and made before entitlement to the bonus. Include employer and other concessional contributions when checking the cap, and consider Division 293 tax where relevant. Use calculator →
Check if the bonus pushes you into a higher bracket
A $10,000 bonus on a $130,000 salary pushes your total to $140,000 — crossing the 37% bracket threshold at $135,001. The extra $5,000 is taxed at 37% instead of 30%. This is real marginal rate effect, not just withholding timing.
