Tax on a $10,000 Bonus in Australia (2025-26)
A $10,000 bonus is not taxed at a special rate in Australia. The actual tax depends on your annual salary, but the payslip withholding can look much higher because the employer annualises the bonus pay run.
Quick answer: a $10,000 bonus is added to your annual income and taxed at your marginal rate. What looks like "bonus tax" is usually higher PAYG withholding, not a separate tax rate.
Worked examples for a $10,000 bonus
| Base salary | Actual tax on bonus | PAYG withholding | Over-withholding | Effective bonus tax rate |
|---|---|---|---|---|
| $70,000 salary | $3,200 | $4,156 | $956 | 32.0% |
| $100,000 salary | $3,200 | $4,329 | $1,129 | 32.0% |
| $150,000 salary | $3,900 | $4,577 | $677 | 39.0% |
What this bonus example means
On the bonus pay run, withholding can be much higher than the actual extra tax created by the bonus itself. The gap usually comes back at tax time if too much was withheld.
This example uses a fortnightly pay cycle for comparison. If your employer pays weekly or monthly, the withholding shape can change, but the main lesson is the same: withholding and actual tax are not identical.
What to know about bonuses in this range
Bonuses between $5,000 and $15,000 are common for annual performance bonuses and retention payments. At this level, the over-withholding effect is significant — your employer's PAYG system can withhold 30-45% of the bonus, even though the actual tax on it may be lower. The gap between withholding and actual tax can be $500-$2,000+, meaning a noticeably larger tax refund. Salary sacrifice into super becomes more meaningful here.
Why withholding looks so high
PAYG withholding on bonuses uses Schedule 5 (or the pay-period annualisation method). Both treat the bonus as if you earn that inflated amount every pay period. A $10,000 bonus on a fortnightly cycle looks like $260,000/year to the withholding formula — pushing the withholding rate well above your actual marginal rate.
Salary sacrifice to super is effective here
A $10,000 bonus salary-sacrificed into super saves $3,200 in tax for someone in the 32% marginal bracket (30% tax + 2% Medicare), while costing only $1,500 in super contributions tax (15%). Net saving: $1,700. Ensure you stay within the $30,000 concessional cap including employer contributions. 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.
