Quick answer: Payroll compliance means paying every worker correctly and on time under the Fair Work Act, the relevant modern award or enterprise agreement, superannuation guarantee law and tax law, and being able to prove it. In Australia from 2026 that includes paying super with every pay cycle (payday super), avoiding intentional underpayments that are now a criminal offence, reporting through Single Touch Payroll Phase 2, and meeting WGEA gender pay gap obligations.
Payroll used to be the quietest function in the organisation. That ended when a run of large employers disclosed underpayments running into the hundreds of millions of dollars, the Fair Work Ombudsman made large-corporate compliance a priority, and Parliament criminalised intentional wage theft. In 2026 the pressure moved from the past to the present tense: payday super removes the quarterly buffer that hid timing errors, and pay transparency rules mean gender pay gaps are published with your name on them.
This guide is written for HR, payroll, finance and people-technology leaders in large Australian organisations, and for their New Zealand counterparts who face a parallel debate on payroll remediation under the Holidays Act. It covers what has changed, where underpayments actually come from, how to audit, and what to demand of your systems.
What is payroll compliance, and what does it cover in Australia?
Payroll compliance is the set of obligations and controls that ensure employees receive their lawful entitlements and that the organisation meets its reporting and payment obligations to government. In Australia the main layers are:
- Minimum entitlements — Source: Fair Work Act 2009, National Employment Standards · What you must get right: Hours, leave, notice, redundancy, right to disconnect, record-keeping and payslips
- Pay rates and conditions — Source: Modern awards (around 120) and enterprise agreements · What you must get right: Classification, base rates, penalties, overtime, allowances, loadings, rostering rules
- Superannuation — Source: Superannuation Guarantee (Administration) Act; payday super from 1 July 2026 · What you must get right: 12 per cent SG on ordinary time earnings, paid so that it reaches the fund within days of payday
- Tax reporting — Source: PAYG withholding, Single Touch Payroll Phase 2 · What you must get right: Correct withholding, disaggregated income reporting each pay event
- State obligations — Source: Payroll tax, long service leave, portable LSL schemes, workers compensation · What you must get right: Thresholds, grouping rules, scheme contributions
- Gender equality — Source: Workplace Gender Equality Act · What you must get right: WGEA reporting for employers with 100+ staff; published employer gender pay gaps
- Transparency — Source: Fair Work Act (pay secrecy ban) · What you must get right: Employees may discuss pay; contracts cannot prohibit it
Compliance is not a payroll-team task. Classification decisions are made in HR, rosters are made by line managers, allowances are triggered by operations, and systems are owned by IT. Underpayments are almost always a chain of small decisions across those functions.
What changed in 2025-2026: payday super, criminal wage theft and the right to disconnect
Three changes dominate the compliance agenda.
Payday super. From 1 July 2026, employers must pay superannuation guarantee contributions at the same time as salary and wages, with contributions expected to reach employees' funds within a short window after each payday rather than quarterly. The practical effect: every pay run is now a super run, and any error in ordinary time earnings, fund details or clearing-house processing surfaces immediately as a shortfall with charges attached. The Superannuation Guarantee rate reached 12 per cent on 1 July 2025.
Criminal wage theft. Since 1 January 2025, intentional underpayment of wages or entitlements is a criminal offence under the Fair Work Act, with substantial penalties for companies and individuals. Honest mistakes remain civil matters, and small businesses that follow the Voluntary Small Business Wage Compliance Code are protected from criminal referral. For large employers the lesson is about evidence: you need to be able to show that underpayments were neither intentional nor the product of reckless indifference, which means documented controls, audits and remediation.
Right to disconnect and related NES changes. The right to disconnect (in force for larger employers from August 2024 and small businesses from August 2025) does not change pay calculations directly, but it changes what counts as working time and increases scrutiny of unpaid out-of-hours work, a classic source of underpayment claims.
Alongside these, the Fair Work Ombudsman continues to pursue large-corporate underpayments and publishes enforceable undertakings that read like a catalogue of system failures: misapplied classifications, annualised salaries never reconciled against award entitlements, rostering systems that did not trigger penalties, and manual workarounds that were never audited.
Where do underpayments actually come from?
Across the public remediation cases, the root causes repeat:
- Classification drift. Employees promoted, re-rostered or moved between awards without their classification being updated.
- Annualised salary without reconciliation. Salaried staff on awards whose actual hours, penalties and overtime were never compared against the annual figure, as award clauses require.
- Time and attendance gaps. Rostering and time systems not capturing actual hours, breaks, split shifts or out-of-hours work.
- Award interpretation configured once and never reviewed. Rules in the payroll engine that were right in 2018 and wrong after an award variation or annual wage review.
- Integration failures. Data lost or transformed between HRIS, time and attendance, payroll and the superannuation clearing house.
- Superannuation on the wrong earnings base. Allowances, bonuses or leave loading incorrectly excluded from ordinary time earnings.
- Manual workarounds. Spreadsheets and off-system adjustments that bypass controls.
Notice that only two of the seven are "payroll" problems. The rest are HR data, operations and systems problems. (This is one reason HRIS and payroll consolidation decisions matter so much; see how to choose and consolidate an HRIS.)
How do you conduct a payroll compliance audit?
A credible payroll audit has five parts. Many organisations now run them annually, with continuous monitoring in between.
- Scope and population. All employees, all awards and agreements, a defined look-back period (six years is the general Fair Work limitation period for underpayment claims).
- Classification review. Compare each employee's recorded classification against their actual duties, qualifications and tenure under the award or agreement.
- Recalculation. Independently recalculate entitlements from source time data and the award rules, then compare to amounts paid. Sampling is acceptable for low-risk groups; full recalculation is expected for high-risk groups such as annualised salary staff on awards, casuals, and shift workers.
- Superannuation and tax check. Recalculate SG on ordinary time earnings for each pay period, verify timing against payday super requirements, and confirm STP Phase 2 reporting matches payroll.
- Controls assessment. Review how award rules are configured and change-managed, how roster and time data flow into payroll, who can make manual adjustments, and how exceptions are logged and approved.
Findings should land in three buckets: remediation (back pay, interest, super charge), root-cause fixes (configuration, process, data), and controls to prevent recurrence. Self-disclosure to the Fair Work Ombudsman and the ATO, with a credible remediation plan, materially changes the regulatory outcome compared with being found.
What does pay transparency require in Australia?
Pay transparency in Australia is a combination of three mechanisms rather than a single law:
- Pay secrecy ban. Since the Secure Jobs, Better Pay reforms, employees have a workplace right to disclose or not disclose their pay, and pay secrecy clauses in new contracts are prohibited.
- WGEA reporting and publication. Employers with 100 or more employees report annually to the Workplace Gender Equality Agency; since 2024 WGEA publishes each employer's gender pay gap, and the reporting dataset has been expanding (including executive remuneration). Employers with 500 or more staff must also have policies or strategies on specified gender equality indicators.
- Positive duty and respect-at-work obligations, which make pay equity part of the broader equality agenda rather than a payroll footnote.
New Zealand has debated mandatory pay gap reporting for several years, and the EU Pay Transparency Directive (which member states must transpose by June 2026) sets the international direction: salary ranges in job ads, a right to pay information, and mandatory gap reporting with joint pay assessments where gaps exceed 5 per cent. Multinationals with European operations are building one approach rather than several.
For the practitioner, the technology implication is clear: you need to be able to run a pay equity analysis (like-for-like comparisons controlling for role, level, tenure and location) from your HRIS and payroll data on demand, explain the gaps, and show the actions taken. (This connects directly to skills-based pay and planning; see strategic workforce planning.)
In practice: a retailer prepares for payday super
A national retailer with 14,000 mostly award-covered staff ran a payday super readiness review in early 2026. The payroll engine calculated SG correctly, but the superannuation clearing-house file was generated in a separate monthly process, fund details for about 3 per cent of staff were stale, and allowance codes added since 2022 had never been mapped to ordinary time earnings. The fixes were unglamorous: move the clearing-house file into the pay-run workflow, validate fund details against the ATO's stapled fund service at onboarding and on change, and add a quarterly review of every new pay code's SG treatment. The team also used the exercise to introduce continuous monitoring: a weekly reconciliation that compares time data, payroll output and super contributions and flags exceptions before payday rather than after.
What should you demand from payroll compliance technology?
Whether payroll sits inside your HCM suite or in a specialist Australian engine, the capabilities that reduce compliance risk are:
- Award and agreement interpretation that is maintained by the vendor through annual wage reviews and award variations, with a documented change log and test evidence.
- Annualised salary reconciliation built in, comparing actual hours and penalties against the salary at the frequency the award requires.
- Time and attendance integration that captures actual hours, including mobile clocking for frontline and out-of-hours work, and flows exceptions to managers.
- Payday super processing inside the pay run, with fund validation and reconciliation to contributions received.
- STP Phase 2 reporting that matches payroll exactly, with correction workflows.
- Continuous compliance monitoring: automated recalculation and exception reporting each pay cycle, not an annual audit alone.
- Pay equity analytics from the same data set, with WGEA reporting outputs.
- Controls: segregation of duties, approval workflows for manual adjustments, immutable audit logs, and reporting that an auditor or regulator can follow.
Ask vendors for reference customers under your awards, their process when an award varies, and what happened the last time one of their customers found an underpayment.
Key takeaways
- Payroll compliance spans Fair Work minimums, awards and agreements, superannuation, tax reporting, state obligations and gender equality reporting; most underpayments originate outside the payroll team.
- Payday super (from 1 July 2026) and criminal wage theft (from 1 January 2025) remove the buffers that hid errors; evidence of controls and prompt remediation is now the defence.
- Run an annual payroll audit with full recalculation for high-risk groups, and move toward continuous monitoring each pay cycle.
- Pay transparency is live through the pay secrecy ban and published WGEA gaps; be able to run and explain a pay equity analysis on demand.
- Demand vendor-maintained award interpretation, built-in annualised salary reconciliation, payday super inside the pay run, and immutable audit logs from any payroll technology.
