What Is Pay As You Go Withholding?
PAYG stands for Pay As You Go. It is the system the ATO uses to collect income tax throughout the year, so you are not left with one large tax payable amount when you lodge your tax return. As an employer, you deduct tax from each employee’s gross pay and send the amount of tax withheld to the ATO. This applies to full-time, part-time, and casual workers, as well as company directors and other workers under voluntary agreements.
If you are a sole trader or contractor, you probably do not pay yourself a formal wage. PAYG instalments are how you pre-pay tax on your business income instead. The ATO calculates your instalment amount or instalment rate based on your latest tax return, and you pay quarterly through your BAS. Withhold too little, and your employees cop a tax bill at EOFY. Underestimate your own instalments, and you will be the one with a surprise.
Income Tax Rates and Tax-Free Threshold for 2025-26
The PAYG withholding tables are based on these income tax brackets for Australian residents in the current financial year:
- $0 to $18,200: No tax (tax-free threshold)
- $18,201 to $45,000: 16c per $1 over $18,200
- $45,001 to $135,000: 30c per $1 over $45,000
- $135,001 to $190,000: 37c per $1 over $135,000
- $190,001 and above: 45c per $1 over $190,000
The 2% Medicare levy is added on top, but the ATO’s withholding tables already include it along with tax offsets like the Low Income Tax Offset (LITO), so employers do not need to calculate these separately. If an employee has a HELP debt or other study loan, additional levies apply once their income passes $67,000. Working holiday makers (visa subclasses 417 and 462) and non-resident workers have separate tax rates and are not eligible for the tax-free threshold.
How This PayG Calculator Works: Gross Pay to Net Pay
The tool works in two directions. Enter a gross pay amount to see how much tax is withheld and what the home pay (take-home) figure will be. Or enter the net pay you want someone to receive, and it works backwards to find the gross amount needed.
Keep in mind that the calculator’s accurate estimate depends on the information you provide. For formal payroll where total deductions include superannuation, expenses, and salary sacrifice, always use ATO-compliant software like Xero, MYOB, or QuickBooks. If you have a second job and have claimed the tax-free threshold from your main employer, your second employer should withhold at the higher “no threshold” tax rate to avoid a shortfall on your tax return.
PAYG and Your BAS
If you have employees, the amount of tax withheld gets reported on your BAS at labels W1 (total payments made) and W2 (total amount withheld). If you are a sole trader on PAYG instalments, those appear at T7, T2 and T8. Most small businesses lodge quarterly. Set the money aside so it is ready when your BAS is due, because that payment belongs to the ATO, not your business. For a full rundown of deadlines, check our guide on BAS due dates.
