What Australian HR software must get right
Reviewed by Mellow Editorial Team, HR & payroll content team
Australian HR software must correctly calculate PAYG withholding, apply the 12% Superannuation Guarantee, handle STP reporting at every pay event, and surface HECS/HELP repayment obligations — all within the current award and NES framework. Get any of those wrong and you face ATO penalties, disgruntled employees, and potential Fair Work liability.
The non-negotiables: what every platform must handle
Before comparing features or pricing, check whether a platform covers the legal basics. In Australia, those are:
PAYG withholding. Income tax is progressive and must be withheld from each payment using the correct tax-free threshold and residency status for each employee. The withholding amount changes as soon as an employee's circumstances change — new TFN declaration, change in residency, secondary employment. Your software needs to apply those changes immediately, not at the next pay run.
Superannuation at 12%. From 2026, the Superannuation Guarantee sits at 12% of ordinary time earnings. Contributions must reach a complying fund on time — late or missed super is a significant liability. Look for software that calculates OTE correctly (overtime generally does not count), schedules payments, and gives you an audit trail.
Single Touch Payroll reporting. STP requires you to report payroll information — wages, tax, super — to the ATO at each pay event, not monthly or quarterly. Finalisation must happen by 14 July each year. Any platform operating in Australia must be STP Phase 2 compliant. If a vendor is vague about their STP status, that is a red flag.
HECS/HELP repayments. Employees with study debts repay them through payroll on a banded scale determined by their annual income. Your software should apply the correct repayment band automatically once an employee discloses a debt on their TFN declaration.
Medicare levy. The standard Medicare levy is 2% of taxable income, already factored into the ATO's withholding schedules — but some employees are exempt or pay a surcharge. The software should handle these variations without manual adjustment.
Award interpretation and leave entitlements
The NES sets the floor: four weeks of annual leave for full-time employees, plus a redundancy-pay scale that increases with years of service. But for most Australian businesses, a Modern Award sits on top of that — setting penalty rates, overtime, allowances, and classification pay points.
Award interpretation is where many platforms fall short. Some provide a library of pre-built awards; others require you to configure the rules manually. Neither approach is foolproof. Pre-built awards go stale when Fair Work updates rates each July. Manual configuration puts the compliance risk squarely on you.
When evaluating software, ask specifically: how are award updates handled, and who is responsible if a rate is wrong? A reputable vendor will be transparent about their update cycle and will flag when Fair Work determinations affect their award library.
Payroll for a mixed workforce
Many Australian businesses use a combination of employees and contractors. The software you choose should make the distinction clear rather than treating all engagements the same way. Contractors do not attract super under the standard rules (though some specific arrangements do trigger obligations), do not appear in STP reporting, and are invoiced rather than paid through payroll.
If you also engage workers outside Australia — whether foreign workers on Australian payroll or Australian employees working internationally — the complexity increases further. Tax residency, double-tax agreement implications, and whether super applies all need to be assessed. How Mellow runs payroll across six countries on one platform covers what that looks like in practice.
What to actually compare when evaluating platforms
Once the compliance foundations are confirmed, the practical comparison comes down to a few things:
Integration with your accounting software. Payroll data needs to flow cleanly to your general ledger. Check whether the integration is native or via a third-party connector, and how it handles cost-centre coding.
Employee self-service. Employees should be able to submit TFN declarations, view payslips, and update their super fund details without going through HR. This reduces admin load and creates a cleaner audit trail.
Reporting depth. Beyond STP, you need payroll reports your accountant and finance team can actually use — by cost centre, by employment type, by pay period.
Localisation versus global reach. Pure Australian platforms are often strong on local compliance but limited if you grow internationally. Global platforms sometimes treat Australia as a secondary market and lag on local regulatory updates. Ask vendors for their update history around the July 2025 award rate changes as a concrete test.
Support and accountability. When something goes wrong — and at some point it will — you need to reach someone who understands Australian payroll law, not a generic support queue. Ask vendors how they handle payroll errors and who bears responsibility for a miscalculation.
The July rate-change test
Every year on 1 July, the Fair Work Commission's national minimum wage increase takes effect and super rates can shift. How a platform handled the 2025/26 transition tells you a great deal about how it will handle future changes. Ask vendors for specifics: when were rates updated, were customers notified, and were any corrections required after the fact? A vendor who can answer that clearly has earned more trust than one who cannot.
