Payroll compliance is the part of running a business that gives no credit for getting it right and no warning before it goes wrong. You will not hear from the Fair Work Ombudsman or the ATO in the years the pay runs are correct. You hear from them, or from an employee, after they have not been.
This payroll compliance guide sets out what Australian payroll compliance actually requires — the payroll obligations, where they come from, what the common payroll mistakes are, and what good payroll governance looks like in practice. It is written for the business owner, finance manager or company accountant who owns the risk, not for a payroll team that already knows the legislation.
This is general information, not professional advice. Payroll compliance legislation changes, and your obligations depend on your awards, your state and your industry.
What is payroll compliance?
Payroll compliance means paying your employees what they are legally entitled to, withholding and remitting the right amounts to the right agencies on time, reporting it in the required format, and keeping proper records that prove all of it.
The word that matters in that sentence is prove. Payroll compliance is not the same as believing your payroll is correct. It is being able to demonstrate, for any of your pay runs, which instrument applied, which of your pay rates was used, how it was calculated and the date it was paid. A business with correct pay and no accurate records is in a weaker position than it thinks.
It also is not one rulebook. Australian payroll sits at the intersection of federal workplace law, federal tax law, federal superannuation law and state payroll tax law — four sets of obligations with different regulators, different due dates and different penalties.
What are the main payroll regulations in Australia?
Fair Work: awards, enterprise agreements and the NES
The Fair Work Act sets the floor. The National Employment Standards cover maximum weekly hours, leave entitlements, notice and redundancy, and they apply to every employee regardless of what anyone signed. Your Fair Work obligations start here.
On top of that sit the modern awards — more than 120 of them — which set minimum pay rates, penalty rates, overtime, allowances and conditions for roles in particular industries and occupations. Roughly two-thirds of Australian employees are covered by one. Enterprise agreements replace the relevant award where they exist, but must leave employees better off overall.
Two things trip businesses up here. First, award coverage follows the work an employee actually does, not their job title or their contract. Second, paying above the minimum wage does not discharge Fair Work obligations — penalty rates, overtime, allowances and loadings are each tested separately. "We pay everyone well" is not a compliance position, and it will not satisfy the Fair Work Ombudsman.
Pay rates change following the Fair Work Commission's annual wage review, and individual awards are varied throughout the year. A payroll setup that is not updated is quietly wrong from the date the change takes effect.
PAYG withholding and STP reporting
If you have employees, you must register for PAYG withholding, withhold tax from wages at the correct rate, report each pay run to the ATO through Single Touch Payroll on or before the day you pay, and remit the withheld amounts by your activity statement due dates.
STP Phase 2 expanded what has to be reported: gross pay is broken into its components — ordinary time earnings, overtime, allowances by type, paid leave, bonuses and so on — rather than reported as one figure. That disaggregation is the point. It lets the ATO see the shape of a payment, which also means the accuracy of your payroll data is now visible to a regulator every single pay cycle.
Superannuation: how and when to pay super
Super guarantee contributions are calculated at the legislated rate — 12% for the 2026–27 financial year — for eligible workers, and paid to a complying fund by the due date. Employees who do not choose a fund are stapled to an existing one, so you must request their super fund details from the ATO rather than defaulting them.
Since 1 July 2026, Payday Super applies. For wages paid from that date, super is paid each time you pay an employee, and it must be received by their fund within 7 business days of payday (20 business days for a new employee or a new fund). The quarterly cycle now applies only to earnings paid up to 30 June 2026.
Two details cause most of the trouble. The super base is not the same as gross pay — the ATO now calls it qualifying earnings, which is built on ordinary time earnings plus salary sacrificed to super; overtime is generally excluded, many allowances are not — so a business that calculates superannuation contributions on the wrong base is wrong on every pay. And you only pay super when it reaches the fund, not when it leaves your account, which makes timing a real risk with a deadline that now falls every pay cycle. Miss it and the ATO assesses the Superannuation Guarantee Charge; the charge itself is now deductible, but the general interest charge and any late payment penalty on it are not.
State and territory payroll tax
Payroll tax is a separate state and territory obligation, unrelated to PAYG withholding despite the similar name. Each jurisdiction sets its own threshold and rate, and if you employ across borders you may need to register in more than one. Contractor payments and grouping provisions catch businesses out routinely — a payment you think is a supplier invoice may be taxable wages.
Payroll records and record keeping
Employee payroll records and pay slips must be kept for at least seven years, in a form that can be produced if asked. Pay slips have prescribed content and must be issued within one working day of payment. Records cannot be false or misleading, and they cannot be altered after the fact — which in practice means your payroll system needs an audit trail, not an editable spreadsheet.
What happens if you get payroll compliance wrong?
The consequences have hardened considerably.
Intentional underpayment of wages is now a criminal offence in Australia, following the Closing Loopholes reforms. That is the change that should reframe how owners think about this: deliberate wage theft is no longer only a civil matter with hefty fines attached.
Short of that, non compliance exposes a business to civil penalties from the Fair Work Ombudsman, back-payment of entitlements with interest, the Superannuation Guarantee Charge, ATO penalties and interest on withholding failures, and state revenue assessments for unpaid payroll tax. Avoiding fines is the obvious motivation; it is not the main one.
Then there are the costs that never appear in a penalty notice. A remediation exercise across several years of payroll data is expensive and slow, and it is usually done by the same finance team still running the current pay runs. Underpayments become public. And employee trust, once a workforce learns it has been underpaid, is not restored by a back payment.
What are the most common payroll mistakes?
Almost all of the common payroll mistakes are structural rather than careless.
Wrong award or wrong classification. An employee placed under the wrong award, or the right award at the wrong classification level, is underpaid consistently and invisibly until someone checks.
Calculating super on gross instead of ordinary time earnings. A single payroll setup error that repeats on every pay for every affected employee.
Treating an annualised salary as a solution. Annualised salary arrangements under many awards carry their own reconciliation obligations — you still have to compare what was paid against what the award would have paid, and make up any shortfall.
Misclassifying workers as contractors. The test is the substance of the relationship, not the invoice. Getting it wrong creates exposure across super, withholding, payroll tax and entitlements simultaneously.
Missing award updates. Pay rates and conditions change; systems that are not maintained do not.
Incorrect employee details in STP. Wrong TFN, wrong date of birth, misused exemption codes — these generate ATO data-matching problems that are tedious to unwind.
Manual timesheet handling. Where hours worked are re-keyed or interpreted by hand, human error enters every pay cycle. This is where award interpretation software earns its place; we have written separately about what award interpretation software does and why payroll still gets it wrong.
What does an Australian payroll compliance checklist look like?
Use this as a starting structure and adapt it to your awards and your industry.
Every pay cycle: timesheets approved before processing; award rules applied to actual hours worked; employees paid correctly and pay slips issued within one working day; STP reporting lodged on or before the payment date; superannuation calculated on qualifying earnings and paid so it reaches each fund within 7 business days; the pay run reconciled to the general ledger.
Every month or quarter: PAYG withholding remitted by the activity statement deadline; payroll tax lodged in each registered jurisdiction.
Every year: award rate changes applied from their effective date; annualised salary arrangements reconciled against award outcomes; STP finalisation declaration lodged; leave entitlements and accruals reviewed.
Continuously: new employees onboarded with correct classification, TFN declaration and super fund details; employee details changes — classification, hours, pay rate — reflected in the system from the date they take effect; regular audits comparing what was paid against what should have been paid.
That last item is the one most small businesses skip, and it is the only one that finds errors before a regulator or an employee does.
Who is responsible for payroll compliance?
Legally, the employer. Not the payroll officer, not the bookkeeper, not the software vendor, and not the outsourced provider.
That matters because responsibility is often felt to sit with whoever runs the pay run, while the obligation sits with the business. A payroll team without the right skills, time or authority to raise problems is a governance failure, not an individual one. And outsourcing payroll transfers the work, not the liability — you remain accountable for what your provider does in your name.
The practical implication: someone at a level that can actually change things needs to own payroll risk, receive reporting on it, and be told when something looks wrong. Getting professional advice early is cheaper than a remediation.
How do you build payroll governance that holds?
Four things, in order of how much difference they make.
Get the payroll setup right. Most errors are configuration errors that repeat. Time spent verifying award mapping, classifications, pay categories and the super calculation base at setup is worth more than any amount of later checking.
Document the process. A written, repeatable procedure with a checklist per pay cycle means the process survives the person who normally runs it being on leave.
Automate the calculation, not the accountability. Payroll software should apply award rules, maintain balances, handle date-driven changes such as public holidays by state, and handle STP reporting without manual intervention. It should also produce an audit trail showing which rule was applied, from which instrument version, and when.
Run regular audits deliberately. Sample real employees against their award. Test your ugliest scenarios — split shifts, on-call, higher duties, someone working across two classifications in a week — before they appear in a remediation. This is how you maintain evidence rather than hope.
Where does the payroll system fit?
Most Australian businesses run payroll in one tool and accounting in another, and reconcile between them. It works, and it costs you something: labour cost arrives in the accounts as a summarised journal, so nobody can see what a job, a site or a production run actually cost once wages were loaded in.
When you choose software that runs payroll inside the same system as accounting, the pay run posts to the general ledger with its cost centres and analytic accounts intact. Payroll accuracy and management reporting stop being two separate problems. That is the position we take with Odoo: award rules configured against your own awards and enterprise agreements, the pay run posting directly to accounting, and no second integration to maintain between the system that calculates pay and the system that reports on it. You can read more at Odoo Payroll Australia, and we support it after go-live through Odoo support.

Frequently asked questions
It means meeting every legal obligation attached to paying employees: correct pay under the applicable award or enterprise agreements, correct PAYG withholding, correct superannuation, correct STP reporting to the ATO, correct state payroll tax, and records that evidence all of it for at least seven years.
Four main sources. The Fair Work Act 2009 and the modern awards made under it govern pay and conditions. The Taxation Administration Act and related law govern PAYG withholding and STP reporting. The Superannuation Guarantee (Administration) Act governs super. State and territory payroll tax acts govern payroll tax in each jurisdiction.
Configure the payroll system correctly against your actual awards, automate the calculation so award rules are applied consistently, document a repeatable process with a per-cycle checklist, keep payroll records with a full audit trail, and run regular audits comparing what was paid against what should have been paid. No single one of those is sufficient on its own.
Every pay cycle. Under Payday Super, which applies to wages paid from 1 July 2026, super guarantee contributions must be received by the employee's fund within 7 business days of each payday (20 business days for a new employee or a new fund). Quarterly payment applies only to earnings paid up to 30 June 2026. Note that payment means received by the fund, not sent.
Employee records covering pay, hours worked, leave, superannuation and any agreements, plus copies of pay slips, kept for at least seven years in a form you can produce on request. They must be accurate records and must not be altered after the fact.
No. Software applies the rules it has been configured with, to the payroll data it is given. It removes human error from calculation, which is significant, but it cannot correct a wrong award mapping, a wrong classification or a timesheet that was never approved. Configuration and process still decide the outcome.
No. PAYG withholding is federal tax you withhold from employee wages and remit to the ATO. Payroll tax is a state or territory tax on your total wages bill above a threshold, paid by you, not withheld from anyone. They are separate registrations with separate due dates.
Technical accuracy with award interpretation, working knowledge of the tax and superannuation obligations, and discipline with process and accurate records. A fourth that matters as much: the confidence to escalate something that looks wrong.
