What is PAYG Withholding?
PAYG Withholding, short for Pay As You Go Withholding, is a system used by the Australian Taxation Office (ATO) that requires employers to withhold a portion of payments made to employees and certain contractors, and remit that amount directly to the ATO. This system ensures that income tax obligations are progressively met throughout the financial year.
Every time an employee is paid, a portion of their income is withheld and forwarded to the ATO on their behalf. These amounts are then applied as credits when the individual lodges their annual tax return.
ATO – PAYG Withholding Overview
Who Needs to Withhold PAYG?
Employers and business operators must withhold PAYG amounts if they:
- Employ staff
- Have contractors with voluntary agreements
- Make payments to other businesses that don’t provide an Australian Business Number (ABN)
If you’re registered for PAYG withholding, you are legally responsible for:
- Withholding the correct amount
- Reporting to the ATO
- Paying the withheld amounts to the ATO
How PAYG Withholding Works
Here’s how the PAYG process typically unfolds:
- Employee Provides a Tax File Number (TFN) Declaration
When starting a job, the employee completes a TFN declaration form, which provides necessary information (e.g. residency status, tax-free threshold) that determines how much should be withheld. - Employer Uses ATO Tax Tables or Tools
Based on the information provided and the employee’s earnings, the employer uses ATO resources (like Schedule 1, Schedule 15, or the ATO tax calculator) to determine the withholding amount. - Amounts Withheld from Gross Pay
This tax amount is subtracted from the employee’s gross pay, with the balance becoming their net pay. - Reporting and Payment to ATO
Employers report and pay the withheld amounts on a regular cycle—usually monthly or quarterly, depending on their withholding status (small, medium, or large). - End-of-Year Reporting via STP
The employer finalises their records at the end of the financial year via Single Touch Payroll (STP), allowing employees to see their income and tax withheld in myGov.

PAYG Withholding vs PAYG Instalments
It’s important not to confuse PAYG Withholding with PAYG Instalments:
- PAYG Withholding: Employer obligation, deducted from employee payments
- PAYG Instalments: For businesses and sole traders to prepay their own income tax
Key Employer Responsibilities
Employers must:
- Register for PAYG withholding with the ATO
- Accurately calculate withholding amounts using ATO tables or software
- Withhold and pay the correct amount on time
- Provide payslips showing gross pay, tax withheld, and net pay
- Submit STP reports with each pay event
- Provide Income Statements via STP (replacing traditional Payment Summaries)
Failing to meet these responsibilities can result in penalties, interest charges, and compliance actions from the ATO.
