Managing payroll is an important part of running a business in Australia. One of the most important components of this is PAYG withholding. Whether you are an employer, contractor, or simply trying to better understand your payslip, having a clear understanding of how this system works can help you stay compliant and avoid costly mistakes.
This guide explains PAYG withholding, how it works, how to calculate PAYG withholding, and what you need to know about rates, thresholds, and refunds.
What is PAYG Withholding?
PAYG withholding (Pay As You Go) is a system used by the Australian Taxation Office (ATO) to collect income tax progressively throughout the year.
In practice, employers deduct a portion of an employee’s earnings and send it directly to the ATO. This helps reduce the chances of employees facing a large tax bill at the end of the financial year. As this process relies on accurate payroll calculations and timely reporting, many businesses choose to use outsourced payroll services to help manage compliance and reduce errors.
PAYG withholding applies to various types of payments, including:
- Salaries and wages
- Bonuses and commissions
- Director fees
- Certain contractor payments
Who Needs PAYG Withholding Registration?
You generally need to register if you:
- Pay employees
- Hire contractors under voluntary agreements
- Make payments to businesses that do not quote an ABN
Registration can be done when applying for an ABN or later through the ATO portal. Once registered, your business is responsible for:
- Calculating withholding amounts
- Reporting to the ATO
- Paying withheld amounts on time
PAYG obligations can also apply when working with contractors. If you work with contractors, it’s important to understand how PAYG rules apply in different situations. You can explore this further in our guide on payroll tax and contractors.
What is ATO PAYG Withholding?
- Income level
- Tax-free threshold claims
- Residency status
- Medicare levy and other adjustments
If you get it wrong, you could face penalties, interest charges, or extra admin work. Staying up to date with ATO guidance is essential for accurate payroll management.
How to Calculate PAYG Withholding
Key Factors That Affect PAYG Withholding Calculation
- Employee income level
- Tax-free threshold claim
- Medicare levy
- HECS/HELP or student loan repayments
- Pay frequency (weekly, fortnightly, or monthly)
Step-by-Step: Calculate PAYG Withholding
- Determine gross pay (before tax)
- Identify pay period (weekly, fortnightly, etc.)
- Check if the employee claims the tax-free threshold
- Use ATO tax tables or calculator
- Deduct the calculated withholding amount
Example Calculation
Let’s say:
- Monthly salary = $5,000
- Employee claims tax-free threshold
Using ATO tax tables:
- Estimated PAYG withholding = $900–$1,000 (based on ATO tax tables)
So:
- Net pay = $4,000–$4,100
- PAYG withholding payable = $900–$1,000
PAYG Withholding Rates (2025–2026)
Current Individual Tax Rates
Taxable Income | Tax Rate |
$0 – $18,200 | Nil |
$18,201 – $45,000 | 16% |
$45,001 – $135,000 | 30% |
$135,001 – $190,000 | 37% |
Over $190,000 | 45% |
The ATO uses these rates to calculate withholding amounts.
PAYG Withholding Threshold
The PAYG withholding threshold determines when tax begins to be deducted.
- The tax-free threshold is $18,200 per year
- Employees earning below this may have minimal or no withholding
- If the threshold is not claimed, higher amounts will be withheld
Understanding this helps ensure accurate deductions and avoids over-withholding.
PAYG Withholding Categories
The ATO classifies businesses based on their annual withholding amounts. This determines how often you must report and pay.
Withholder Type | Annual Withholding | Reporting Frequency |
Small | Up to $25,000 | Quarterly |
Medium | $25,001 – $1M | Monthly |
Large | Over $1M | Twice weekly |
Choosing the correct category is essential for meeting reporting deadlines and avoiding penalties.
