What Is Single Touch Payroll? A Guide for Australian Employers

Australian employers generally need to report payroll information to the Australian Taxation Office (ATO) through Single Touch Payroll (STP) each time they pay employees. STP-enabled payroll software sends information such as salary or wages and PAYG withholding as part of the pay cycle. The obligation applies to employers covered by STP reporting rules, although the specific information and timing can depend on the employer’s circumstances. Using software or an external payroll provider can help with the process, but it does not remove the employer’s responsibility to keep payroll data accurate and ensure reports are lodged. In practice, employers need a reliable process for checking employee records, approving pay runs, confirming successful submissions, and correcting errors promptly.

What Is Single Touch Payroll?

STP is the Australian Government’s system for reporting payroll information to the ATO through compatible payroll software. It connects reporting with the regular process of paying employees, rather than leaving employers to report the same information as a separate task at a later date. Reported information can include salaries and wages and PAYG withholding, along with superannuation information and other payroll details required through the STP process.

The ATO introduced STP in stages, first for employers with 20 or more employees and then for employers with 19 or fewer employees. It is now a core reporting obligation for Australian employers within the system. The ATO’s STP guidance explains the system and its role in employer reporting.

How Does STP Work?

STP is generally handled through payroll software rather than a separate government portal that an employer updates manually after every pay run. The software submits the required information to the ATO as part of the payroll process. A typical workflow is:

1. Prepare and check payroll information. Confirm employee pay and deductions, tax withholding, superannuation details, and other relevant entries.
2. Process the pay run. Pay employees through the employer’s normal payroll process. The timing of payments depends on the employer’s pay cycle.
3. Submit the STP report. Use the payroll software to send the required information to the ATO in connection with the pay run.
4. Check the submission and address errors. Confirm that the report was lodged and investigate discrepancies. Correct errors through the payroll and STP reporting process rather than leaving them unresolved.

Software can automate the transmission of information, but it cannot ensure that the underlying employee details or payroll entries are correct. Employers remain responsible for checking information such as pay categories and tax settings before the report is submitted.

Who Is Responsible for Accurate Reporting?

An employer may use an internal payroll team, payroll software, or an external provider to carry out parts of the process. Regardless of the arrangement, the business should understand what has been submitted on its behalf and have a way to review and correct it. Outsourcing payroll does not automatically protect an employer from penalties if reporting obligations are not met. The source article notes that safe harbour protection generally applies only when the third-party provider is also a registered tax or BAS agent. Employers should therefore check a provider’s registration status and maintain appropriate oversight.

Clear ownership helps prevent tasks from falling between teams. The exact arrangement will vary with the size of the business, but responsibilities should be understood for maintaining records, approving changes, processing payroll, reviewing submissions, and resolving errors.

Why Does STP Matter to Employers?

Because reporting happens alongside payroll, employers need dependable processes throughout the year rather than relying on a separate year-end reporting exercise. Regular reporting can reduce the need to reconstruct payroll records months later. It can also help teams identify inconsistencies earlier, when investigating the relevant pay run and employee record may be more straightforward.

This makes accurate, current employee information important. A mistake in a record or payroll entry can affect both the employee’s pay and the information sent to the ATO. Reviewing payroll inputs before each pay run and checking that the report was successfully lodged helps employers spot problems while the relevant details are still easy to verify.

What Should Employers Review?

The information and reporting requirements can depend on the employer’s circumstances and the software being used. Employers should treat STP as a data-quality responsibility as well as a submission task. Before finalizing a pay run, review employee names and identifying details, pay amounts and classifications, and PAYG withholding. Check superannuation information and any leave or employment changes that affect payroll. Also review adjustments or back payments and confirm that the STP report was successfully lodged.

The ATO’s overview of STP is a useful reference for understanding the system and the role of STP-enabled software.

What Common Problems Can Affect STP Reporting?

Many reporting issues begin with ordinary payroll problems rather than a failure of the technology. Addressing the underlying process can help prevent the same issue from affecting later pay runs.

Incomplete employee information. Missing or incorrect details can affect both payroll and reporting. A structured employee onboarding process helps ensure payroll receives the information it needs before the first pay run.

Changes that do not reach payroll in time. Promotions, pay increases, leave changes, terminations, and changes in working arrangements can all affect payroll. HR and payroll teams need a dependable way to share approved changes before payroll is finalized.

Overreliance on automation. Automation can reduce manual work, but it does not replace review. Payroll teams should investigate unusual pay amounts and unexpected deductions. They should also check failed reports and records that do not match approved changes.

Delayed corrections. Leaving an error unresolved can make it harder to trace across later pay periods. Promptly investigating the issue and correcting the underlying payroll information helps limit the chance that it will recur.

How Does STP Affect Employees?

Employees may see STP reflected in the payroll information associated with their income and tax records. Because employers report payroll information throughout the year, the ATO can receive information as employees are paid rather than only after an annual reporting event.

Accurate reporting depends on accurate payroll records. Employees can review their payslips and keep their personal details current with their employer. If pay or tax withholding appears incorrect, raising the issue promptly gives the employer an opportunity to check the underlying record and correct it through the appropriate process.

How Can Employers Prepare for STP?

Employers can make the process more dependable by confirming that their payroll software supports STP reporting and assigning clear responsibility for payroll approval and submission review. They should maintain accurate employee records from onboarding onward and document how the business handles pay changes, corrections, and off-cycle payments. After each pay run, check that the related report has been lodged. If an external provider is involved, confirm its registration status and agree who will review submissions and resolve problems.
