The payroll ran on time. Everyone was paid. No concerns were raised.
It is easy to assume that means everything is working as it should.
But paying people regularly and on time does not necessarily mean they are being paid correctly.
Payroll risks are not always obvious. They can arise from how an award or enterprise agreement has been interpreted, an inaccurate timesheet, a rostering practice, an outdated system rule or a manual workaround that only one person understands.
Some issues affect only certain employees, shifts or working arrangements, allowing them to continue unnoticed for months or even years.
The biggest payroll compliance risks often start well before the pay run.
Payroll Does Not Operate in Isolation
Payroll is often viewed as the function responsible for processing employee pay. The team receives the information, runs the payroll and corrects any issues that arise.
However, accurate pay depends on decisions and information coming from across the organisation.
HR interprets awards and enterprise agreements and establishes employment conditions. Operational managers prepare rosters, review timesheets and approve hours worked. Finance oversees labour costs and financial controls. Payroll then applies those conditions through the payroll system.
If the information, interpretation or process is incorrect at any point, payroll may process exactly what it has been given and still produce the wrong result.
Common causes of payroll errors include:
- Incorrect classifications or pay rates.
- Late, missing or inaccurate timesheets.
- Inadequate timesheet checks and approvals.
- Employee changes not reaching payroll on time.
- Incorrect award or enterprise agreement interpretation.
- Missed or misapplied allowances, overtime, penalties or minimum engagements.
- Mismatches between rosters and timesheets.
- Award or enterprise agreement updates not being reflected in the payroll system.
- Organisational arrangements not being configured correctly.
Payroll compliance is, therefore, not the responsibility of payroll alone. HR, payroll, finance, operations and organisational leaders all have a role to play.
Payroll Software Does Not Guarantee Compliance
Organisations often place a great deal of confidence in their payroll software.
However, a payroll system can only apply the rules it has been configured to apply, using the information entered into it.
It does not independently determine whether an award or enterprise agreement has been interpreted correctly, whether an employee has selected the right work type or whether a manager has approved accurate information. A system can process payments reliably while still applying the wrong rule.
Payroll teams are also often expected to be payroll processors, industrial relations interpreters and payroll systems specialists at the same time. That is a significant expectation, particularly for lean payroll teams focused on meeting strict pay deadlines.
When a system issue is identified, someone in payroll may attempt to correct the rule so employees can be paid correctly. However, without specialist system knowledge and thorough testing, changing one rule can unintentionally affect another allowance, employee group, work type or working arrangement.
Understandably, payroll employees may be reluctant to make changes if they are concerned about creating further issues. The immediate problem is then often managed manually.
The employee’s pay is corrected, but the underlying system or process issue remains.
When Manual Workarounds Become Normal
Manual adjustments are sometimes necessary, particularly when an urgent issue needs to be addressed before a pay run.
The concern is when the same adjustment is required regularly.
A common response is to:
- Correct the affected employee’s pay
- Check whether anyone else is affected
- Add the issue to the pay-run checklist
- Manually check it again in future pay cycles
This may keep payroll running, but it does not resolve the original issue.
Over time, the manual check can become an informal control. In many organisations, only one payroll employee understands why the check exists and what needs to be done. When that person is absent or leaves the organisation, critical checks can easily be missed.
Repeated manual adjustments, back payments and pay corrections should not simply be accepted as normal.
They should be reviewed to determine whether the cause relates to employee or manager behaviour, an unclear process, an incorrect industrial interpretation or a payroll system issue.
A manual adjustment may be appropriate as a temporary solution. If it happens repeatedly, it is usually a sign that further investigation is required.
Complex Working Arrangements Expose Hidden Risks
Some payroll issues are easy to identify. Others only occur when several employment conditions or system rules interact.
Examples include:
- Shifts crossing midnight or pay periods.
- Interactions between overtime and penalty rates.
- Sleepovers involving active work.
- On-call, call-back and minimum engagement requirements.
- Broken shifts and minimum rest periods.
- Different allowance rates across employee groups.
- Changes to classifications or working arrangements.
An allowance may, for example, apply at different rates across employee groups. If the payroll or timesheet system cannot identify the correct rate automatically, employees may need to select from multiple work types when entering their timesheets.
This relies on employees choosing the correct work type, managers identifying errors, and payroll validating the entry. In practice, payroll may be unable to confirm every selection without reviewing each employee individually.
What appears to be a simple allowance issue can therefore become a broader system configuration, timesheet design, training and audit risk.
These issues are often difficult to detect through the normal payroll process and may require a detailed review of awards or enterprise agreements, employment conditions, rosters, timesheets and payroll rules across different scenarios.
Payroll Compliance Requires Shared Accountability
There has long been debate about whether payroll should sit within HR or finance.
HR understands industrial relations, employment conditions and workforce practices. Finance understands financial controls, labour costs and budgeting. Operations understands how work is rostered and performed.
Payroll sits at the intersection of all three areas.
The more important question is not necessarily where payroll reports, but whether HR, payroll, finance and operations have clear responsibilities, communicate effectively and apply employment conditions consistently.
Executives should also have visibility of significant or recurring payroll issues.
Boards do not need to be involved in individual pay corrections or the operational details of each pay run. However, material or systemic payroll risks may require board oversight because of their potential financial, legal, employee and reputational impact.
Payroll is usually one of an organisation’s largest expenses and one of its most important obligations. It should receive the investment, expertise and attention that come with that responsibility.
What Better Payroll Governance Looks Like
Correcting an employee’s pay is only the first step. Once an issue has been identified, the organisation should:
- Identify and document the cause.
- Confirm the correct award or enterprise. agreement interpretation
- Determine whether other employees are affected.
- Correct the process or payroll system configuration.
- Test a range of employee and shift scenarios.
- Check whether the change affects any other payroll rules.
- Communicate the issue and outcome to relevant teams.
- Review the first live pay runs after the change.
- Ensure the process does not rely on one person’s knowledge.
- Schedule regular reviews of payroll rules and configuration.
Testing is critical. It is not enough to test a straightforward employee working ordinary hours. Organisations also need to test the more complex scenarios that occur within their actual workforce.
This could include a shift crossing midnight, an employee receiving a different allowance, work performed during a sleepover or an employment change taking effect partway through a pay period.
A rule has not necessarily been fixed because it worked correctly in one scenario.
Could Your Organisation Demonstrate That Its Payroll Is Compliant?
Consider the following questions:
- When was our payroll system configuration last reviewed?
- How many manual adjustments, corrections and back payments do we process?
- Are recurring issues being resolved or simply added to a checklist?
- Does critical payroll knowledge sit with one person?
- Can we demonstrate how our payroll rules were interpreted, configured and tested?
- Do HR, payroll, finance and operations apply employment conditions consistently?
- Do managers understand the importance of accurate rostering, timesheets and timely approvals?
If these questions are difficult to answer, it may be time to undertake a payroll health check.
A payroll health check should look beyond whether payroll runs on time. It should review the relevant awards and enterprise agreements, employment contracts, classifications and pay rates, allowances and other pay conditions, rostering and timesheet practices, system configuration, manual adjustments, back payments, controls, procedures and key-person dependency.
At Zest, we work across people, processes and systems to identify payroll risks, understand the causes of recurring issues and develop practical, sustainable solutions.
A Zest payroll health check incorporates both system and compliance reviews, providing greater confidence that your people are not only paid on time, but paid correctly.
