Understanding Staff and Contractor Expenses in Australia, The Essentials
When running a business in Australia, one of your biggest financial commitments will be staff and contractor expenses, covering wages, superannuation, and other related costs like payroll tax and workers’ compensation. The key question for business owners is: What exactly do I need to pay, and what are the differences between employees (staff) and contractors?
The short answer is: if you hire employees, you are responsible for wages, super, leave entitlements, and taxes. If you engage contractors, your obligations depend on whether they are truly independent or considered employees under law. Some contractors may still require you to pay super or withhold PAYG.
This article will walk you through everything you need to know, clearly and simply, about staff and contractor expenses so you can meet your obligations, budget properly, and stay compliant with Australian tax and employment laws.
Staff (Employee) Expenses Explained
What Counts as a Staff Member?
A staff member, legally called an employee, is someone you hire to work in your business under your direction. You control their work hours, tools, and how they perform their tasks.
Common Employee Expenses You Must Budget For
1. Wages and Salaries
The most obvious cost. Wages are usually paid hourly, weekly, or fortnightly, while salaries are annualised.
2. Superannuation Guarantee (Super)
Employers must pay the minimum super guarantee (currently 11% as of July 2023) on an employee’s ordinary time earnings (OTE). This rises gradually over the coming years.
3. Leave Entitlements
Employees are entitled to paid leave, including:
- Annual Leave
- Personal (Sick/Carer’s) Leave
- Long Service Leave (after a qualifying period)
- Parental Leave
4. PAYG Withholding
Employers are responsible for withholding tax from employees’ wages and remitting it to the ATO.
5. Payroll Tax
Payroll tax is a state-based tax payable when your total wages exceed the threshold for your state or territory.
6. Workers’ Compensation Insurance
Mandatory insurance that covers employees in case of work-related injury or illness.
Contractor Expenses Explained
Who is a Contractor?
A contractor is typically engaged to provide services on an independent basis. They usually invoice you for their services and control how they complete the work.
However, many businesses misunderstand this. Some contractors may actually be deemed employees by the ATO based on how they work for you, regardless of what their contract says.
Contractor Costs and Obligations
1. Payments to Contractors
Contractors set their rates and invoice you. You don’t process them through payroll unless required under specific conditions.
2. Superannuation for Contractors
This often surprises business owners, you may have to pay super for contractors if:
- They are paid primarily for their labour (not for supplying equipment or materials).
- They work under your direction.
3. PAYG Withholding for Contractors
You may have PAYG obligations if the contractor does not quote an ABN or under voluntary agreements.
4. GST Considerations
Contractors may charge GST on their invoices if registered.
5. No Leave Entitlements
Contractors are not entitled to leave benefits like employees.
Key Differences Between Staff and Contractors
| Expense | Employee | Contractor |
| Wages/Fees | Salary or hourly wage | Set fees (invoiced) |
| Superannuation | Compulsory | Sometimes required |
| PAYG Withholding | Always required | Sometimes required |
| Leave | Yes | No |
| Payroll Tax | Yes (if thresholds met) | Usually No |
| Workers’ Comp | Yes | Sometimes, depending on state law |
Hidden and Overlooked Costs
Training and Onboarding
Employees usually require initial and ongoing training. This adds to upfront and recurring costs.
Equipment and Uniforms
For employees, you may need to supply tools, equipment, or uniforms. Contractors typically supply their own.
Administration and Compliance Costs
Processing payroll, super, tax filings, and Fair Work compliance for employees takes time and may require dedicated staff or external bookkeeping support.
Practical Tips for Managing Staff and Contractor Costs
1. Use Contracts and Agreements
Whether hiring staff or engaging contractors, always have a written agreement outlining roles, rates, and obligations.
2. Check the ATO’s Contractor vs Employee Tests
Misclassifying a worker can trigger penalties and back-pay obligations. The ATO offers clear guidance to help you assess this.
3. Budget for True Cost of Employment
Factor in all costs, not just wages or contractor fees. Super, payroll tax, workers’ comp, and leave entitlements add significantly to total expenses.
4. Consider Outsourcing Payroll or Using Payroll Software
This reduces compliance risk and streamlines processing.
5. Stay Updated
Tax rates, super guarantee percentages, and employment laws change regularly. Stay informed to avoid compliance risks.
Final Thoughts
Managing staff and contractor expenses properly is essential for the financial health of your business and for meeting your legal obligations. The costs go beyond simple wages or contractor fees, they include superannuation, payroll tax, leave entitlements, and more. Understanding the full picture will help you budget better and stay compliant.
If you’re unsure about your specific situation, consider speaking with a registered tax agent or accountant.
