Am I an Employee or Contractor?

The label on your contract does not determine your status — the ATO and Fair Work look at the totality of the working relationship. Key factors:

If you are working out the downstream tax effect of that classification, the Australian income tax guide is the best place to compare how wages, deductions, and tax rates fit together.

C

You set your own hours

C

You work for multiple clients

C

You quote for a specific result

C

You bear financial risk (e.g., fix defective work at your cost)

C

You supply your own tools and equipment

C

You can subcontract or delegate the work

E

The employer sets your hours

E

You work exclusively or mainly for one business

E

The work is ongoing and integral to the business

E

The employer provides equipment and training

E

You are paid by time (hourly/weekly), not by result

E

There is a policy of no subcontracting

No single factor is decisive. The ATO weighs all factors together. Use the ATO's Employee/Contractor Decision Tool at ato.gov.au for a definitive assessment.

Tax Obligations as a Contractor

Income Tax — Self-Assessment

No tax is withheld from contractor invoices (unless you enter voluntary withholding arrangements). You lodge an annual tax return and pay tax on your net profit (revenue minus deductible expenses). If you expect to owe more than $500 at tax time, the ATO will ask you to pay PAYG instalments quarterly, based on last year's income or a notional tax amount.

Record-keeping usually matters more for contractors than employees, so the tax return checklist is a useful companion once you start invoicing and claiming expenses.

GST — Quarterly BAS

If registered for GST, you lodge a Business Activity Statement (BAS) quarterly (or monthly/annually by choice). You remit GST collected from clients minus GST credits you paid on business purchases. The net amount is due to the ATO within 28 days after each quarter end.

Superannuation — Your Responsibility

Unless a client is legally required to pay your super (see FAQ below), you need to fund it yourself. A practical starting point is to set aside at least 12% of gross income so you are not falling behind an employee on the same earnings. If your cash flow allows it, concessional contributions can also be tax-effective.

If you want the cap rules, Division 293 thresholds, or bring-forward rules in one place, read the superannuation contributions guide.

Converting Contractor Rate to Equivalent Salary

This is where people often underquote. A contractor day rate is not the same thing as an employee salary, because the contractor has to fund costs that an employee receives indirectly. In practice, you usually need to cover:

Super (12% from 2025-26)+12%
Annual leave (4 weeks = ~7.7%)+7.7%
Sick leave (10 days = ~3.8%)+3.8%
Public holidays (~9 days = ~3.5%)+3.5%
Income protection insurance+1–2%
Accounting/tax fees+0.5–1%
Contract gaps / business development+5–10%
No workers compensation safety netRisk
Total loading above employee salary~35–40%

As a starting point, many contractors multiply the salary they want to replicate by 1.35 to 1.40. On that basis, matching a $120,000 employee package usually means generating about $162,000 to $168,000 in contractor revenue before expenses.

Before accepting a rate, run it through the contractor calculator so you can compare the headline day rate with the after-tax reality.

Frequently Asked Questions

Do I have to pay super as a contractor?

It depends. If you are engaged primarily for your labour (rather than a result) and you work under a contract wholly or principally for your personal labour and skills, the engaging business must pay super contributions on your behalf — even if you invoice through an ABN. If you are a genuine business contractor providing a result-oriented service through a company or trust, you generally manage your own super.

What daily rate is equivalent to a $100,000 employee salary?

As a sense-check, start with annual salary divided by about 220 working days, then add a loading for super, leave, insurance, admin, and downtime between contracts. On a $100,000 salary, that usually lands around $545–$636 a day, but the right figure depends on how steady the work is and which costs you are carrying yourself.

Do contractors pay GST?

You must register for GST if your annual turnover exceeds $75,000. Once registered, you add 10% GST to your invoices and remit the GST collected to the ATO (less any input tax credits). Many contractors register voluntarily even below the threshold to appear professional and to claim input tax credits.

What is sham contracting?

Sham contracting is when an employer disguises an employment relationship as an independent contracting arrangement to avoid paying entitlements like super, leave, and workers compensation. It is illegal under the Fair Work Act. The ATO and Fair Work Ombudsman both actively investigate sham arrangements.

Can I claim more tax deductions as a contractor?

Yes. Contractors can claim all genuine business expenses: home office costs, professional subscriptions, tools and equipment, work-related travel, business insurance, and accounting fees. Employees can only claim work-related expenses not reimbursed by their employer, which is usually a narrower scope.

Do I need an ABN to contract?

You need an ABN to invoice for goods or services in Australia. Without one, clients are required to withhold 47% tax from your payments (top marginal rate + Medicare levy). Registering an ABN is free through the ABR website.
