Contractor vs Employee — The Legal Breakdown

What Is the Difference Between a Contractor and an Employee?

An employee works inside the employer's business under the employer's direction, while an independent contractor operates their own separate business and delivers a defined result.

The distinction is not a matter of personal preference. Australian employment law, administered jointly by the Australian Taxation Office and the Fair Work Ombudsman, classifies every worker based on the substance of the working relationship — not the label on a contract. A worker labelled “contractor” on paper but treated as an employee in practice is legally an employee.

Three consequences flow from the classification. First, taxation: employers withhold PAYG income tax for employees but pay contractors in full via invoice. Second, superannuation: the employer pays the 12% Super Guarantee for employees in FY2025-26, whereas genuine contractors manage their own super. Third, entitlements: employees receive 4 weeks paid annual leave, 10 days personal/carer's leave, and workers' compensation coverage — contractors receive none. Use our Australian tax calculator to model the take-home pay difference for a specific salary.

The classification also determines minimum wage coverage. Employees fall under the National Employment Standards and relevant Modern Awards, guaranteeing at least $24.10 per hour (the national minimum wage from 1 July 2024). Contractors negotiate their own rates with no statutory floor, which is why commercial contracting rates sit 25% to 50% above equivalent employee salaries.

How Does the ATO Determine Your Status?

The ATO applies a “Multi-Factor Test” rooted in Australian common law — no single factor is decisive, and the test examines the totality of the working relationship across 6 primary indicators.

Following the High Court's 2022 decisions in Construction, Forestry, Maritime, Mining and Energy Union v Personnel Contracting Pty Ltd and ZG Operations Australia Pty Ltd v Jamsek, courts now prioritise the terms of the written contract — provided those terms reflect a genuine arrangement and are not a sham. The 6 indicators the ATO evaluates are:

1. Ability to sub-contract or delegate: A contractor has the right to hire others to do the work. An employee performs the work personally.
2. Basis of payment: Contractors invoice for a result (fixed quote, per-project fee). Employees receive a regular wage or salary per hour, week, or month.
3. Equipment, tools, and other assets: Contractors supply their own tools, vehicles, and software. Employees use the employer's equipment.
4. Commercial risk: Contractors bear financial risk — they fix defects at their own cost and carry their own professional indemnity, public liability, and income protection insurance. Employees bear no such risk.
5. Control over the work: Contractors decide how, when, and where they perform the work. Employees follow the employer's directions on method, location, and hours.
6. Independence / integration: Contractors operate visibly as a separate business (own ABN, own branding, multiple clients). Employees are integrated into the employer's operations (wearing uniforms, using company email addresses, attending staff meetings).

A worker who satisfies 4 or more of these indicators as a contractor is more likely to be genuinely independent. A worker who fails most indicators — for example, using the employer's tools, working fixed rosters, having no right to delegate, and receiving hourly pay — is almost certainly an employee regardless of what the contract states. The ATO publishes a free “Employee/Contractor Decision Tool” on ato.gov.au that walks through each factor interactively.

A classic sign of sham contracting is forcing a worker to go and get an ABN before you will give them shifts, while continuing to dictate their hours and uniform just like regular employees.

Contractor vs Employee Comparison Table

Employees and contractors differ across 12 key attributes covering tax, entitlements, risk, and work arrangements — the table below summarises every major distinction in one place.

Tax Obligations: Contractor vs Employee

Employees have income tax automatically deducted each pay cycle through the PAYG withholding system, while contractors receive the full invoiced amount and manage all tax payments independently.

Employee Tax Obligations

The employer uses ATO withholding schedules to deduct the correct amount of income tax from each pay. The employee receives their take-home pay already net of tax. At the end of the financial year, the employee lodges a tax return — typically by 31 October (or the following May if using a registered tax agent). Any over-withheld tax is returned as a refund. Employees claim work-related deductions such as uniforms, tools, and home office expenses on their individual return. Use the Tax Refund Guide to understand what deductions apply.

Contractor Tax Obligations

Contractors receive the gross invoice amount with no tax deducted. They are responsible for:

1. Setting aside approximately 30% of every payment for income tax, based on the FY2025-26 income tax brackets (16% on income from $18,201 to $45,000, 30% from $45,001 to $135,000, 37% from $135,001 to $190,000, and 45% above $190,000).
2. Registering for GST once annual turnover exceeds $75,000, adding 10% to every invoice and remitting it to the ATO.
3. Lodging quarterly Business Activity Statements (BAS) by the 28th of the month following each quarter — 28 October, 28 February, 28 April, and 28 July.
4. Paying quarterly PAYG instalments once the ATO issues an instalment notice (typically after the first year of contracting).
5. Maintaining records of all business income and expenses for 5 years, including invoices, bank statements, and receipts.

Contractors claim business deductions directly against their assessable income — home office costs, vehicle expenses, professional development, accounting fees, and equipment depreciation. These deductions reduce taxable income before income tax brackets apply. Need to work backward from a net figure? Use the Gross Pay Calculator to reverse-calculate your gross.

What Are the GST Obligations for Contractors?

Contractors earning above $75,000 in annual turnover must register for GST, charge 10% on every invoice, and remit the collected GST to the ATO via quarterly or monthly BAS lodgements.

This means if you quote $100/hour to a client, the invoice actually becomes $110 (plus GST). The client pays $110, you keep $100, and $10 goes to the ATO. Many first-time contractors underestimate this cash-flow requirement and end up with a sizeable BAS bill at the end of each quarter.

If you earn under $75,000, GST registration is optional. However, registering allows you to claim GST credits on business expenses (equipment, software, insurance), which can offset your liability. Contractors who purchase significant assets — vehicles, computer equipment, or specialised tools — in their first year of business often benefit from voluntary registration even below the $75,000 threshold.

Employees never interact with GST. Their salary is not subject to GST, and they do not lodge BAS returns. This administrative burden is one of the hidden costs of contracting that workers overlook when comparing contractor vs employee arrangements.

Super Entitlements for Contractors

Genuine independent contractors pay their own superannuation voluntarily, but the Superannuation Guarantee (Administration) Act 1992 creates a critical exception: employers must pay the 12% Super Guarantee for any contractor hired “wholly or principally for their personal labour and skills.”

If a contractor is hired wholly or principally for their personal labour and skills, the employer must still pay the 12% Super Guarantee on top of their invoice.

This exception targets sole traders who function economically like employees — a freelance web developer billing hourly, a sole-trader electrician on a long-term engagement, or a contract bookkeeper working 3 days per week for a single client. The test asks: is the hiring business paying for the contractor's personal effort, or for a deliverable that the contractor's business produces using any combination of staff and resources?

If you hire a solo graphic designer on an hourly rate to do design work just because they are good at it, the ATO classifies them as an employee for superannuation purposes only. You must pay their super. If you hire a massive plumbing company to fix a roof, and they send an anonymous plumber out, that is a true B2B contract and no super is owed.

Contractors who do not receive employer super contributions can still make personal concessional (before-tax) contributions up to the $30,000 annual cap and claim a full tax deduction. Non-concessional (after-tax) contributions are capped at $120,000 per year. Read the full breakdown in our Superannuation Guide.

Financial Comparison: Contractor Hourly Rate vs Employee Salary

A contractor must charge at least 30% to 50% more per hour than the equivalent employee hourly rate to achieve the same net financial position after accounting for lost leave, superannuation, insurance, and unpaid downtime.

The table below models a full-time employee earning $100,000 per year against a contractor who needs to match that total remuneration package. The employee's total package includes super, leave loading, and WorkCover — all paid by the employer.

The contractor in this example needs to earn $70 to $78 per hour to match the $100,000 employee's total package. This represents a 38% to 54% premium over the employee's effective hourly rate of $50.60. Run the precise calculation for your own salary using the Contractor vs Employee Calculator.

What Are the Risks of Sham Contracting?

“Sham contracting” occurs when an employer deliberately disguises an employment relationship as a contracting arrangement to avoid paying entitlements — the Fair Work Ombudsman penalises offenders with fines of up to $469,500 per contravention for companies and $93,900 per contravention for individuals.

Beyond the civil penalties, sham contracting triggers 3 additional financial consequences:

1. Backpayment of superannuation: The employer must pay all unpaid Super Guarantee amounts at 12% (or the rate applicable at the time), plus the Superannuation Guarantee Charge (SGC), which includes a nominal interest component of 10% per annum and an administration fee of $20 per employee per quarter. The SGC is not tax-deductible.
2. Backpayment of leave entitlements: The employer owes all accumulated annual leave, personal leave, and any applicable redundancy pay — potentially spanning multiple years. Long-service leave liabilities accrue after 7 to 10 years depending on the state.
3. Backpayment of Award underpayments: If the worker was covered by a Modern Award, the employer must make up the difference between what was paid and the Award minimum, including overtime, penalty rates, and allowances. Review common Award structures on our Award Rates page.

Industries with the highest rates of sham contracting enforcement include construction, cleaning, hospitality, transport and logistics, and IT consulting. The Fair Work Ombudsman conducts targeted audits in these sectors annually. In FY2023-24, the FWO recovered over $473 million in underpayments across all enforcement activities.

There is no “innocent mistake” defence if the employer “reasonably should have known” the worker was an employee. The onus falls on the employer to prove the arrangement is genuine.

How to Switch from Contractor to Employee

Switching from contractor to employee requires a formal transition covering 5 administrative steps — the employer must restructure the legal arrangement, payroll registration, and insurance coverage.

1. Sign a new employment contract: The contractor agreement terminates and a written employment contract replaces it, specifying the role, salary, hours, and applicable Modern Award or Enterprise Agreement.
2. Register in the employer's PAYG system: The employee completes a Tax File Number (TFN) declaration. The employer begins withholding income tax each pay cycle using ATO withholding schedules. Learn more about the deduction process in our PAYG Withholding Tables guide.
3. Commence Super Guarantee payments: The employer pays 12% super on top of the agreed salary from the first day of employment. Payments are due quarterly — within 28 days of the end of each quarter (28 October, 28 January, 28 April, 28 July).
4. Enrol in workers' compensation insurance: State-based WorkCover schemes cover the new employee immediately. The employer absorbs this cost, which ranges from 0.3% to 8% of payroll depending on the industry and state.
5. Adjust the pay rate: The gross salary is typically lower than the contractor's invoice rate because the employer now bears on-costs including super, leave accrual, and WorkCover. A contractor earning $78/hour commonly transitions to an employee salary of $100,000 to $105,000 per year.

Leave entitlements (annual leave, personal leave, long-service leave) begin accruing from day one of the employment relationship. The transition does not carry over any prior service as a contractor for leave-accrual purposes, unless the employer agrees otherwise in writing.

What Changed in FY2025-26?

The Super Guarantee rate increased to 12% from 1 July 2025 (up from 11.5% in FY2024-25), reaching the legislated ceiling set by the Treasury Laws Amendment (2025 Measures) — the rate is not scheduled to increase further.

Key FY2025-26 changes affecting the contractor vs employee decision:

• Super Guarantee rate: Increased from 11.5% to 12%, adding $500 per year in employer costs for every $100,000 of employee salary. This widens the gap between contracting and employment, as contractors who self-fund super now contribute more.
• Income tax brackets: The Stage 3 tax cuts (effective 1 July 2024) remain in place. The 30% bracket now applies from $45,001 to $135,000, benefiting both contractors and employees earning in this range. The 37% bracket starts at $135,001, and the top 45% rate begins at $190,001.
• HECS-HELP threshold: The minimum repayment threshold rose to $67,000 (up from $54,435 in FY2023-24), and the system shifted to a marginal repayment model at 15 cents per dollar over the threshold. Contractors with HELP debts must factor this into their quarterly tax planning.
• Concessional super cap: Remains at $30,000 for FY2025-26. Contractors using super as a tax-minimisation strategy benefit from the full deduction on personal contributions up to this cap.
• Maximum super contribution base: Set at $62,500 per quarter for FY2025-26. Employers are not required to pay SG on earnings above this threshold, which equates to an annual salary of $250,000.

These changes increase the total cost of employment by approximately $500 per $100,000 of salary compared to FY2024-25, making the financial case for genuine contracting marginally stronger for high-income workers who can structure deductions effectively.

What Insurance and Leave Do Contractors Miss Out On?

Contractors receive zero paid leave and must purchase all workplace insurance at their own expense — these two costs represent the largest hidden gap between contracting and employment income.

• Annual leave: Employees receive 4 weeks (20 days) paid leave per year under the National Employment Standards. Contractors who take 4 weeks off sacrifice approximately 7.7% of their annual billable revenue.
• Personal / carer's leave: Employees receive 10 days paid personal leave per year. Contractors receive nothing — illness or caring responsibilities translate directly into lost income.
• Long-service leave: Employees accrue long-service leave after 7 to 10 years (varies by state). Contractors have no equivalent entitlement.
• Public holidays: Employees receive 8 national public holidays paid (plus state-specific additions, totalling 10 to 13 days depending on the jurisdiction). Contractors forfeit this income or must work the day.
• Workers' compensation: Employers take out WorkCover insurance for their employees. True independent contractors must pay for their own income protection insurance (typically $800 to $2,500 per year) and public liability insurance (typically $400 to $1,500 per year).

Combined, lost leave and insurance costs add $15,000 to $25,000 per year in hidden expenses for a contractor earning the equivalent of a $100,000 employee salary. This is why commercial contracting rates are set 25% to 50% higher than internal employee salaries.
