What is Payroll?

Payroll is the process of calculating employee wages, PAYG withholding tax, superannuation contributions, leave entitlements, and deductions while reporting payroll data to the ATO through Single Touch Payroll (STP). Australian payroll must also comply with Fair Work laws, Modern Awards, payroll tax obligations, and employee record-keeping requirements. To streamline this process, a business can outsource payroll services to a reputable provider.

Key ATO Payroll Definitions

• Single Touch Payroll (STP): Single Touch Payroll is the ATO’s real-time payroll reporting system.
• PAYG Withholding: PAYG withholding obligations require employers to deduct income tax from employee wages and send those amounts to the ATO.
• Superannuation Guarantee (SG): The Superannuation Guarantee is the compulsory retirement contribution employers must pay for eligible employees.
• Modern Awards and Fair Work Compliance: Most Australian employees are covered by Modern Awards under the Fair Work Act 2009.

How Does Australian Payroll Work Within the STP and ATO Framework?

Australian payroll works through a connected reporting system between employers, payroll software, the ATO, superannuation funds, and Fair Work compliance requirements. Every pay run involves calculating wages, withholding PAYG tax, paying super contributions, and submitting payroll data to the ATO through Single Touch Payroll (STP).

Unlike older payroll systems where employers reported wages annually, STP now sends payroll information to the ATO every time employees are paid. This gives the ATO near real-time visibility into employee earnings, PAYG withholding, and superannuation obligations.

The Role of Single Touch Payroll (STP)

Single Touch Payroll is the ATO’s mandatory digital payroll reporting framework. Employers must use STP-enabled payroll software to report payroll information each pay cycle.

• Superannuation liabilities

• Overtime
• Leave payments
• Termination payments

How the ATO Monitors Payroll Compliance

The ATO now cross-checks payroll data against:

• BAS lodgements
• Superannuation payments
• STP submissions
• Employee tax returns
• Payroll tax reporting
• Contractor reporting systems

How Does Payroll Tax Registration Work by State and What Are the 2026 Thresholds?
