HR and payroll for professional services in Australia
Reviewed by Mellow Editorial Team, HR & payroll content team
Professional services firms in Australia — accountants, lawyers, consultants, engineers, architects — share a common payroll and HR profile: highly educated, often HECS-indebted employees, award or agreement-based pay with complex overtime rules, and a workforce that can shift quickly between full-time, part-time, casual and contractor arrangements.
Awards and agreements that apply
Most professional services employees are covered by the Professional Employees Award 2020, which applies to engineers, scientists, information technology professionals and some management consultants. Legal staff often fall under the Legal Services Award 2020. Accounting and finance staff can fall under the Clerks — Private Sector Award 2020 depending on their role classification.
Getting the award right matters for more than compliance. The classification level determines the minimum pay rate, overtime rules and allowances. A misclassified graduate engineer paid as a clerical worker, or vice versa, creates both an underpayment liability and a potential Fair Work dispute. Review classifications when you hire and again when an employee is promoted or their duties change substantially.
Many mid-to-large professional services firms move employees onto enterprise agreements, which must pass the Better Off Overall Test (BOOT). An agreement can simplify payroll by setting a flat salary that absorbs certain allowances, but it cannot strip out National Employment Standards entitlements.
Leave entitlements and how they affect payroll
Under the National Employment Standards, full-time employees accrue four weeks of paid annual leave per year. Shiftworkers may accrue five weeks. Personal/carer's leave accrues at ten days per year. These apply regardless of award or agreement.
Professional services firms often have additional leave practices — purchased leave, study leave, exam leave — that sit on top of statutory minimums. These need clear written policies and, where they affect pay calculations, consistent treatment in your payroll system. Purchased leave, for example, is typically funded by a pay reduction spread across the year; that reduction must be reflected in PAYG withholding calculations.
Long service leave is governed by state and territory legislation, not a single national standard. The accrual rates and portability rules differ by jurisdiction, which matters if your firm operates across multiple states.
Payroll tax and contractor classification
Payroll tax is a state and territory tax on wages above a monthly or annual threshold. Rates and thresholds vary by state. Because professional services firms often use contractors and consultants, payroll tax grouping provisions and contractor deeming rules are worth understanding carefully.
Many states deem contractor payments to be wages for payroll tax purposes unless a specific exemption applies — for example, if the contractor provides services to the public generally, or if the engagement is short-term. A senior consultant engaged exclusively through your firm, invoicing through a company, may still generate a payroll tax liability. If your contractor spend is significant, a payroll tax review is worth doing with your accountant before you grow past any state threshold.
HECS/HELP repayments in professional services payrolls
Professional services workforces skew heavily towards university graduates, which means HECS/HELP debt repayments are a routine payroll obligation rather than an occasional one.
Repayments are withheld through the payroll on a banded scale based on income. As an employer, your obligation is to withhold the correct amount — which means your onboarding process must include a tax file number declaration or the ATO's online commencement forms that capture whether an employee has a study or training support loan.
If an employee does not declare a debt and you withhold the standard PAYG amount only, the shortfall is the employee's problem at tax time rather than yours — but it creates friction. Good onboarding eliminates it.
STP reporting and payroll compliance obligations
From 1 July 2026, the Superannuation Guarantee rate is 12% of ordinary time earnings. Contributions must go to a complying fund or, where an employee has not chosen a fund, to their stapled fund (identified through the ATO). In professional services, salary packaging arrangements are common; make sure super is calculated on the correct ordinary time earnings base and not inadvertently reduced by packaged items.
Every pay event must be reported to the ATO through Single Touch Payroll (STP). Year-end finalisation — where you confirm each employee's income statement — must be completed by 14 July. For most professional services firms using a modern payroll platform, STP reporting is automatic at each pay run. The risk area is off-cycle payments, bonuses and termination pays, which can be forgotten or reported in the wrong period.
Termination pays deserve particular attention. Redundancy entitlements under the NES are calculated on years of service and must be correctly classified for tax purposes — genuine redundancy payments are taxed differently from ordinary termination payments — and the correct STP reporting codes applied.
Managing a mixed workforce of employees and contractors
Professional services firms regularly blend employees and independent contractors. The classification matters for super, leave, payroll tax and, since the High Court's decision in CFMMEU v Personnel Contracting, for whether the written contract actually reflects the real working relationship.
As a practical discipline, review contractor arrangements when the engagement length extends, when the contractor works exclusively for you, or when you direct their work in ways that look more like employment. If in doubt, a written assessment against the ATO's employee/contractor decision tool is a defensible starting point.
