Are Bonuses, Commissions and Overtime Taxable in Australia?
Bonuses, commissions and overtime payments received through employment are generally part of your employment income and are normally subject to PAYG withholding.
The way payroll calculates withholding can depend on the type of payment, the period it relates to and how it is processed.
This is why a payslip containing a large bonus or commission may show a noticeably larger amount of tax withheld than one of your normal payslips.
PAYG withholding is money withheld during the year. Your final tax outcome depends on your total assessable income, deductions, offsets and other relevant information when your tax return is assessed.
What Is a Bonus?
A bonus is generally an additional payment made in recognition of performance or services. It may be based on individual performance, company performance, sales results or another employment arrangement.
Some bonuses relate to a particular period of work, while others may be one-off payments that do not relate to one specific pay period.
What Is Commission Income?
Commission is commonly paid as a reward for performance or service and may be calculated as a percentage of sales, transactions or other business results.
Commission is common in industries such as real estate, recruitment, sales, finance and other performance-based roles.
What Is Overtime Pay?
Overtime is additional pay for work performed outside or beyond ordinary working hours under the relevant employment arrangement.
Where overtime is processed as part of the normal pay cycle, the additional amount can be included with the other earnings for that pay period when withholding is calculated.
Bonus
An additional payment commonly linked to performance, services or a one-off employment event.
Commission
Performance-based income that may be calculated from sales, transactions or another agreed measure.
Overtime
Additional earnings for work outside ordinary hours, depending on your employment conditions.
Penalty Rates
Higher rates may apply for weekends, public holidays or particular shifts under an award or agreement.
Why Does Tax Look Higher on a Bonus Payslip?
Many workers become concerned when they receive a larger-than-usual payslip and see a much larger amount withheld.
This does not necessarily mean the entire extra payment has been taxed at one permanent tax rate.
PAYG withholding is calculated by payroll using ATO withholding rules. Additional payments such as bonuses and commissions can require a different calculation depending on the period they relate to.
A Worker Receives a Normal Wage Plus a Bonus
A Nepali worker normally receives their regular fortnightly salary. In one pay cycle, the employer also pays a performance bonus.
That payslip may show substantially more PAYG withholding than a normal fortnight. This does not by itself tell the worker what their final annual tax liability will be.
At tax time, the worker's full-year employment income and other relevant tax information are considered together.
Does a Bonus Have a Special Tax Rate?
It is misleading to think that every bonus is simply taxed at one special fixed “bonus tax rate”.
Employers calculate withholding using the applicable ATO PAYG withholding rules. The method can depend on whether the additional payment relates to one pay period, several pay periods or an undefined period.
Your final income tax is determined based on your tax return rather than by looking at the withholding percentage on one payslip alone.
How Are Commissions Treated for PAYG Withholding?
Commissions can be treated as additional payments for withholding purposes.
If the commission relates to work performed across more than one pay period or an undefined period, specific additional-payment withholding methods can apply.
If it relates to a single pay period, it may instead be added to the employee's other earnings for that period when withholding is calculated.
How Is Overtime Treated?
Overtime that is normally processed shortly after the work is performed is generally treated as part of the normal pay cycle when it is paid.
It is different from a genuine back payment that should have been paid in an earlier period.
This distinction can matter because back payments have separate withholding rules.
What Is the Difference Between Overtime and a Back Payment?
A back payment is generally an amount that should have been paid in an earlier period but was paid later.
For example, an employer may discover that wages were underpaid several months earlier and then pay the missing amount.
Normal payroll timing for overtime is not automatically treated as a back payment simply because the overtime was worked in the previous pay cycle.
What About Weekend and Public Holiday Penalty Rates?
Penalty rates are additional amounts paid under an award, enterprise agreement or employment arrangement for working at particular times.
They form part of employment earnings and should appear correctly in your payroll records.
Whether a particular payment also forms part of the earnings base used for super can depend on its classification and the applicable super rules.
Does Super Apply to Bonuses and Commissions?
Super treatment depends on the nature of the payment and the applicable super guarantee rules.
From 1 July 2026, Payday Super rules apply and employers generally need to calculate super on qualifying earnings and pay contributions in line with the new payday requirements.
Commissions are included within qualifying earnings under the current Payday Super framework. The treatment of other payments can depend on their classification, so employees should check their payslip and super records rather than assuming every additional payment is treated identically.
Extra pay can affect PAYG withholding and may also affect super calculations. The treatment depends on the type of payment and how it is classified in payroll.
Can Overtime Push You Into a Higher Tax Bracket?
Extra income increases your total taxable income. If your total annual taxable income crosses into a higher marginal tax bracket, only the portion within that higher bracket is taxed at the higher marginal rate.
It does not mean all of your income suddenly becomes taxed at that rate.
Does More Overtime Always Mean You Lose More to Tax?
Working additional hours can increase both your gross earnings and the tax withheld from your pay.
However, focusing only on the amount withheld from one payslip can be misleading.
Your overall tax result depends on your total income and other tax information across the financial year.
Why Might Your Refund Change After Receiving a Bonus?
A bonus increases your employment income and the employer also withholds tax from the payment.
Whether you eventually receive a refund, owe tax or have little change depends on the relationship between your total tax liability and the PAYG amounts withheld during the year.
A bonus does not guarantee either a larger refund or a tax bill.
Bonus, Commission and Overtime: What Should You Check?
| Payment | What to Check |
|---|---|
| Bonus | Gross amount, PAYG withheld, payment description and income statement reporting. |
| Commission | Commission amount, period it relates to, withholding and payroll classification. |
| Overtime | Hours, overtime rate, gross pay and PAYG withholding. |
| Penalty rates | Weekend, public holiday or shift rate shown on the payslip. |
| Back payment | What period the payment relates to and how payroll reported it. |
| Super | Whether the relevant payment is included in the applicable super earnings base. |
Check Your Payslip Carefully
When you receive a bonus, commission or significant overtime payment, review the payslip instead of looking only at the amount deposited into your bank account.
Check the normal wage and additional payment amounts.
Review the tax withheld from the pay cycle.
Check whether the amount is shown as bonus, commission, overtime or another payment type.
Review relevant employer super information and your super account records.
Compare the current figures with earlier payslips for obvious inconsistencies.
What Should Appear in Your Income Statement?
Employment payments reported through payroll contribute to the information shown in your income statement.
Before lodging your tax return, check that the income information is complete and that your employer's statement is finalised where required.
Do not rely only on one payslip when preparing your tax return for the whole year.
What If Your Bonus Was Paid After 30 June?
Timing can matter when determining which income year a payment belongs to.
If you are unsure which financial year a particular payment should be reported in, review the payment date, income statement and relevant payroll records before lodging.
What If the Bonus Is Incorrect on Your Payslip?
If the amount, tax withheld or payment description appears incorrect, raise the issue with your employer or payroll team.
If an employer later corrects the payroll information, check whether your income statement has also been updated before lodging your tax return.
What If You Already Lodged and Then the Employer Corrects the Payment?
If corrected employer information changes amounts already reported in a lodged tax return, review whether the return needs to be amended.
Do not assume a payroll correction can simply be ignored after lodgement.
Bonuses and Multiple Jobs
If you work for more than one employer, a bonus from one job can make your overall income situation more complicated.
PAYG withholding is performed by each employer based on the information available to that employer. At tax time, income from all relevant jobs is considered together.
This is one reason why workers with several employers should review all income statements before lodging.
Bonuses for Nepali Students Working in Australia
Nepali international students may receive overtime, weekend penalty rates, public holiday pay or occasional bonuses from casual employment.
Keep your payslips and check the income statement for all employers, especially if you changed jobs or worked several casual jobs during the year.
Bonuses for Nepali Full-Time Workers
Full-time employees may receive annual performance bonuses, sales incentives, commissions or overtime payments depending on their role.
These additional payments should be considered together with your regular salary when reviewing your overall tax position.
Common Misunderstandings About Bonus and Overtime Tax
- thinking every bonus is taxed at one fixed special rate
- assuming a large withholding amount means the money is permanently lost
- thinking all income is taxed at the highest marginal rate reached
- assuming overtime is tax-free because it was earned outside normal hours
- confusing normal overtime with a genuine back payment
- assuming every bonus, commission and overtime payment has identical super treatment
- looking only at one payslip instead of full-year income
- lodging before checking that employer information is correct
What to Prepare Before Tax Time
If your income varied significantly during the year because of bonuses, commissions or overtime, prepare your records before lodging.
- income statements from all employers
- recent and year-to-date payslips
- bonus or commission statements where available
- records of other income
- eligible deduction records
- super records where relevant
