If your payroll looks fine on payday, that does not always mean it will hold up under scrutiny. The real test comes when an employee questions a rate, the ATO asks for STP evidence, or Fair Work wants records that must be accurate, accessible, and preserved for years.
- A payroll audit in Australia should start with six questions about your own records, payslips, STP, system controls, manual processes, and audit evidence, because Fair Work and the ATO inspect proof, not assumptions.
- A strong payroll setup can show time and wages records kept for 7 years, payslips issued within one working day of payment, and STP reporting that supports finalisation by 14 July.
- Risk usually appears in the gaps between systems, spreadsheets outside payroll, undocumented award interpretations, unclear ownership of corrections, or no usable audit trail for changes.
- You can test your setup by reviewing historical record retrieval, sample payslips, STP event evidence, software versions, and a mock audit pack.
- If your business has complex awards, EBAs, frequent roster changes, or 20 to 500 employees, audit readiness matters more than whether payroll feels smooth most of the time.
These questions help you assess whether your current payroll process is genuinely controlled, not just operational on the surface. In practice, a strong payroll setup is one that can produce clean evidence quickly, explain exceptions clearly, and show how Australian compliance is maintained as rules change.
What does a payroll audit actually check in Australia?
In Australia, Fair Work and the ATO make payroll audits evidence based. Auditors check time and wages records, payslips, STP data, approvals, and the controls behind manual changes.
A payroll audit is not just a recalculation of gross pay. It tests whether your business can prove why each employee was paid that amount, under which award, classification, contract, or enterprise agreement, and with what approvals. That means records, audit trails, and system logic matter as much as the dollar figure.
Fair Work rules make record keeping central. Time and wages records must generally be kept for 7 years, be legible, in English, readily accessible to a Fair Work Inspector, and not be altered unless correcting an error. A common misconception is that a tidy payslip alone proves compliance. It does not if the source records are missing, unclear, or changed without traceability.
A strong payroll audit also checks tax and reporting integrity. STP, superannuation files, leave balances, deductions, and employee masterfile changes all form part of the evidence chain.
Why should you audit your payroll setup before a problem appears?
A payroll review is far cheaper before an issue becomes remediation. Fair Work disputes and ATO reviews expose weak payroll processes very quickly.
Many businesses assume payroll is fine because employees are being paid and no one is complaining. That is not enough. The right audit questions test whether your process would survive scrutiny if a regulator, external auditor, or employee asks for evidence. Asking those questions early helps you spot weak controls before they become expensive.
‘Fair Work and the ATO inspect proof, not promises’
If your team cannot explain who approved a backpay adjustment, where the supporting record sits, and how the change was logged, that is a warning sign.
“E-Payoffice supports Australian businesses with 20 to 500 employees, a range where payroll controls need to be formal, documented, and repeatable.”
What are the 6 payroll audit questions to ask about your current setup?
Start with six evidence questions. A strong payroll setup should answer them with records, sample reports, and named control owners, not assumptions or verbal reassurance.
These questions work because they map directly to the evidence points regulators and auditors can inspect. Use them for an internal review, an outsourced payroll check, or an annual compliance review.
- Can we produce 7 years of time and wages records that are legible, in English, and readily accessible?
- Do we issue payslips within one working day of payment, including when key payroll staff are on leave?
- How do we manage STP Phase 2 reporting, error corrections, and the finalisation declaration due by 14 July?
- How do we interpret awards or EBAs, handle classification changes, and review manual overrides or spreadsheet inputs?
- What payroll software, version, integrations, and manual processes are part of our payroll setup, and who owns system changes?
- What audit ready evidence can we produce on request, approvals, exception reports, change logs, STP files, super files, and remediation records?
A practical scoring method is simple, answers supported by live examples should rank higher than answers built around intention. Another common misconception is that a smooth monthly payroll means the control environment is strong. Often the opposite is true if the real work happens outside the platform.

How do you verify payroll records and payslips step by step?
Records and payslips are the first live test. Fair Work treats them as core evidence because they prove what was paid, when, and why.
Step 1 is to pull records for a small sample across different scenarios, one current employee, one terminated employee, one salaried employee, and one hourly employee with overtime or allowances. The point is not scale. The point is whether your process can retrieve accurate source records without delay.
Step 2 is to inspect format and timing. Fair Work says employees should receive a payslip within one working day of being paid, even when staff are on leave. Ask how your process ensures this happens automatically and what control catches failures.
Step 3 is to trace the payslip back to source inputs. Check start and finish times, leave approvals, rate tables, allowances, deductions, and any backpay. A practical tip is to pull a historical record from several years back. If retrieval is slow or partial, audit readiness is weak.
How should you test STP reporting and year end finalisation?
STP compliance is continuous, not annual. ATO rules require reportable withholding payments paid through payroll to be sent via STP and then finalised by 14 July.
Step 1 is to map what your payroll setup reports through STP Phase 2 and how pay items are classified. If no one can explain how earnings, tax, and employment information are categorised, error risk rises quickly when corrections are needed.
Step 2 is to reconcile year to date payroll values to the STP files sent during the year. This is where hidden mismatches appear, especially after backpays, terminations, or manual journals. A common misconception is that STP removes year end work. It reduces duplicate reporting, but finalisation still matters.
Step 3 is to test the finalisation process itself. Your team should be able to show who reviews year end totals, who approves the finalisation declaration, and how exceptions are resolved before 14 July. If the employer reports throughout the year and finalises correctly, the corresponding payment summaries and annual PAYG withholding payment summary report are not required.
What should you ask about payroll software, versions, and manual workarounds?
Software names, versions, and manual steps matter. ATO e Audit guidance allows requests for payroll systems, ERP links, and manual processes used to meet tax obligations.
Ask which payroll platform is used, which version is live, how updates are controlled, and what interfaces connect time and attendance, rostering, finance, and HR systems. Then ask the harder question, where do spreadsheets still sit? A manual step is not automatically bad. An undocumented manual step is.
If your team handles a complex allowance, award interpretation, or termination payout offline, ask who prepares it, who checks it, and how it is re entered into payroll. A practical test is to review one real example of an exception workflow, including the approval trail and the permanent record.
Security and data governance sit inside the same question. Some businesses also need to know where payroll data is hosted and whether payroll work is offshored. Those details matter because location, access control, and accountability affect breach response and audit access.
“E-Payoffice states its payroll platform is hosted by Microsoft Azure in Sydney and Melbourne and that nothing is off-shored.”
How does outsourced payroll compare with in house payroll for audit readiness?
Outsourced payroll is often more audit ready than a lean internal team, when responsibilities, approvals, and exception handling are explicit.
An internal payroll function can be strong when it has deep business context, stable staff, and disciplined controls. It can also fail quietly when knowledge sits with one person, leave cover is weak, or legislative updates are handled reactively. That single point of failure risk is common in growing businesses.
An outsourced provider can bring specialist knowledge, repeatable workflows, and better segregation of duties. From conception data should be analysed prior to ‘going live’. If your internal team still owns timesheet approvals, or award mapping, then audit quality depends partly on your own upstream controls.
A useful decision rule is this, if your business has complex awards, multiple locations, or frequent roster driven changes, then outsourced payroll often improves audit discipline. If your payroll is simple and your internal controls are mature, in house may remain efficient.
“E-Payoffice uses a Sydney based qualified team and a dedicated payroll specialist model, software that has online audits for most fields.”
How do you review awards, super, and deductions without missing hidden risk?
Most wage risk sits in interpretation, not arithmetic. Modern awards, EBAs, superannuation rules, and deductions create error points that basic gross to net checks can miss.
Step 1 is to map the governing instrument for each employee group. That means the award or EBA, classification, ordinary hours pattern, overtime rules, allowances, penalties, and leave loading rules. A common misconception is that underpayments usually start with the base rate. They often start with the wrong classification or missed penalty logic.
Step 2 is to recalculate targeted scenarios. Use roster heavy periods, public holidays, sleepovers, higher duties, annual leave, termination payments, or salary absorption arrangements if they apply. If the payroll engine handles this automatically, regular manual checks should be done to ensure nothing is missed.
Step 3 is to trace superannuation and deductions back to source authority. Confirm contribution calculations, salary sacrifice treatment, and deduction approvals. If super is processed electronically, ask how remittance files are validated and how rejected transactions are monitored.
Which documents should you be able to produce during a payroll audit?
An audit ready payroll setup can produce a document pack quickly. If records, approvals, and change logs are scattered across email and spreadsheets, the control is weak.
Ask for this document set before a problem appears, not after. The pack should be clear enough that a third party can follow the lifecycle of a pay run from approved inputs to final reports.
- Time and wages records: records kept for 7 years, legible, in English, and readily accessible
- Payslip evidence: current and historical payslips, with proof that issue timing meets the one working day rule
- STP evidence: submission reports, correction records, and support for the finalisation declaration
- System evidence: payroll software names, versions, integrations, and any documented manual processes
- Control evidence: approval workflows, audit trails, exception reports, remediation logs, and role ownership
When is a payroll health check enough, and when do you need a full payroll audit?
A payroll health check suits early risk screening, while a full payroll audit suits suspected underpayments, regulator contact, or transaction due diligence.
A health check is usually the right first step when you are growing quickly, adding awards, changing processes, or unsure whether your current setup has obvious control gaps. It can identify where to look harder without forcing a large project straight away. E Payoffice, as a market leader example, offers payroll health check downloads for businesses that want an initial screening before deciding on deeper review.
A full payroll audit is the better choice when there are employee complaints, repeated pay adjustments, uncertain award coverage, inherited payroll data from an acquisition, or a regulator has made contact. If the issue could involve backpay, penalties, or director level sign off, go straight to a broader audit scope.
The trade off is speed versus certainty. A health check is faster and cheaper, but it may not quantify historical exposure. A full audit takes more work, but it gives decision makers a clearer basis for remediation and next steps.
