The decision to become a contractor in Australia is one of the most consequential financial choices you can make — and the numbers are frequently misunderstood in both directions. Some people wildly overestimate contractor income; others underestimate how much of that higher day rate they'll actually keep. This guide gives you the full financial comparison, including everything contractors must self-fund that employees take for granted.

Are You Actually a Contractor? The ATO Rules
Before getting to the numbers, it's important to understand what legally distinguishes a contractor from an employee in Australia — because the distinction has significant tax and entitlement implications.
The ATO uses a multi-factor test rather than simply looking at what you call yourself. Key indicators of being a contractor include:
- You can subcontract the work or delegate to others
- You are paid for a result, not for hours worked
- You supply your own tools and equipment
- You bear the commercial risk if the work is done incorrectly
- You can work for multiple businesses simultaneously
Indicators of being an employee (regardless of what your contract says) include being directed how and when to do the work, being paid by the hour, and working exclusively for one business over an extended period. The ATO can reclassify a contractor arrangement as employment if the substance looks like employment — with significant back-tax and penalty consequences for the engaging business.
The 2024 High Court decisions (CFMMEU v Personnel Contracting and ZG Operations v Jamsek) tightened this area significantly. If you are uncertain about your classification, get advice from an accountant.
The Full Financial Comparison: $120,000 Salary vs. $800/Day
Let's take a concrete example. An experienced IT project manager is considering leaving a permanent role paying $120,000 per year (plus super) for a contract role paying $800 per day.
Many people in this situation think: $800 × 5 days × 52 weeks = $208,000 per year. That's a $88,000 raise — surely this is obviously better?
Not so fast. Here's what the contractor must fund themselves:
What the Permanent Employee Receives
| Component | Value |
|---|---|
| Salary | $120,000 |
| Superannuation (11.5% in 2025-26) | $13,800 |
| 4 weeks annual leave (paid) | $9,231 (included in salary) |
| 10 days personal/sick leave (paid) | $2,308 (included in salary) |
| 11 public holidays (paid) | $2,538 (included in salary) |
| Workers compensation insurance | ~$600 (employer pays) |
| Professional indemnity cover | Often included or minimal |
| Total employer cost | ~$136,738 |
What the Contractor Actually Earns
Contract: $800/day. Calculating the realistic annual income:
- Billable days in a year: 260 working days
- Less: 4 weeks annual leave (unpaid): −20 days
- Less: sick days / unplanned downtime (5 days average): −5 days
- Less: public holidays (11 days, not billable): −11 days
- Less: contract gaps between engagements (3–4 weeks average for IT): −15 days
- Realistic billable days: 209 days
- Gross contract revenue: 209 × $800 = $167,200
Now subtract the self-funded costs:
- Superannuation (self-funded, 11.5%): −$19,228
- Professional indemnity + public liability insurance: −$2,000
- Accountant / tax agent fees: −$1,500
- Income protection insurance: −$2,500
- Professional development / training: −$1,500
- Home office costs, equipment: −$1,200
- Net pre-tax contractor income: approximately $139,272
At a marginal tax rate of 37–45% on income above $120,000, the after-tax difference between the contract and the salary narrows considerably.
The "Contractor Premium": Is It Worth It?
In the example above, the contractor earns approximately $139,272 net (before tax) compared to the employer total cost of $136,738 for the equivalent employee. The contractor's advantage is surprisingly thin once all costs are accounted for — and they carry all the risk of downtime, illness, and finding the next engagement.
The real contractor premium kicks in when:
- The day rate gap is larger (e.g., $1,200/day vs. a $120,000 salary)
- You operate through a company structure with access to lower company tax rates and income splitting
- You have very consistent work with minimal gaps between contracts
- Your skills are highly in-demand and you can maintain pricing power
Salary vs. Day Rate Equivalents — A Quick Reference Table
| Annual Salary (inc. super) | Break-even Day Rate (220 days) | Break-even Day Rate (200 days) | "Worth it" Day Rate (~20% premium) |
|---|---|---|---|
| $80,000 | $363 | $400 | $480+ |
| $100,000 | $454 | $500 | $600+ |
| $120,000 | $545 | $600 | $720+ |
| $150,000 | $681 | $750 | $900+ |
| $180,000 | $818 | $900 | $1,080+ |
These figures assume 220 billable days (high utilisation) or 200 billable days (moderate), and include a 20% uplift as the "worthwhile" premium to compensate for additional risk and self-funded costs.
Operating Structure: Sole Trader vs. Company
Most Australian contractors operate as either a sole trader or through a company (Pty Ltd). The main differences:
- Sole trader: Simple, cheap to set up, income taxed at personal rates. Better for lower incomes (under ~$120,000) and short-term contracting.
- Company: Higher setup and ongoing accounting costs (~$2,000–$3,500/year for compliance), but profits taxed at 25% corporate rate (for base rate entities). Can be highly efficient at higher incomes. Allows shareholder salary splits where a spouse is involved in the business.
The crossover point where a company structure becomes tax-efficient is generally around $120,000–$150,000 in contractor income, depending on personal circumstances. Get advice from an accountant before choosing.
Sham Contracting Warning
"Sham contracting" occurs when a business misrepresents an employment relationship as independent contracting to avoid entitlements and super obligations. It is illegal under the Fair Work Act, and the Fair Work Ombudsman actively investigates complaints.
If you are engaged as a "contractor" but work exclusively for one client, cannot subcontract, are directed in how to perform your work, and use their equipment, you may actually be an employee — with back entitlements owing. The ACTU and Fair Work Australia both provide free advice lines for workers in this situation.
Frequently Asked Questions
Do contractors get paid superannuation?
Contractors who are engaged primarily for their labour (as opposed to providing a result using their own tools) may be entitled to employer super contributions even if they hold an ABN. The rules are complex and depend on the specific arrangement. Many contractors simply fund their own super — but it is worth checking whether your client is required to contribute.
Can I get a mortgage as a contractor?
Yes, but it requires more documentation than a PAYG application. Lenders typically want 12–24 months of contractor history, a current contract, and tax returns showing consistent income. Some specialist lenders offer contractor mortgages with more flexible criteria. Work with a mortgage broker who has experience with contractor applications.
What insurance do I need as a contractor?
Most professional contractors need: professional indemnity insurance (covers errors and omissions), public liability insurance (covers third-party injury or property damage), and income protection insurance (covers you if you cannot work due to illness or injury). Workers compensation is generally only required if you have employees of your own.
