Contractor vs Employee Calculator — Compare Your Take-Home

How Does Contractor vs Employee Pay Compare?

A contractor earning the same gross rate as an employee takes home less cash and no entitlements unless the contract rate is at least 30% higher. The Australian tax system treats employees and contractors differently across income tax withholding, superannuation, Medicare levy, and leave entitlements, creating a significant gap in total compensation value.

On a $100,000 gross rate, an employee's total package value (including 12% superannuation guarantee paid by the employer) is $112,000. A contractor at the same $100,000 receives no employer super, no paid leave, and no workers compensation coverage. After self-funding super and covering business expenses, the contractor's disposable income drops below the employee's take-home pay. Use our Income Tax Calculator to see the exact income tax breakdown at any salary level.

This contractor vs employee calculator for FY2025-26 applies the current Australian tax brackets, the 12% SG rate, and the 2% Medicare levy to produce an accurate side-by-side comparison. The calculation factors in deductible business expenses, voluntary super contributions, and the true cost of lost entitlements like annual leave, personal leave, and employer-provided insurance.

What Are the Key Differences Between Contractors and Employees?

Contractors and employees differ across 7 core dimensions: tax collection, superannuation, Medicare, GST, leave, insurance, and expense deductions. The comparison table below summarises every difference that affects your take-home pay and total package value.

Employees benefit from the employer paying superannuation on top of salary, PAYG withholding that eliminates large tax bills, and access to the Leave Calculator entitlements under the Fair Work Act. Contractors trade these benefits for flexibility and greater deduction opportunities.

Who Uses This Contractor vs Employee Calculator?

This Australian tax calculator serves 4 primary user groups evaluating whether to work as an employee or operate under an ABN as a sole trader or contractor.

• Employees considering contracting — IT professionals, consultants, and tradespeople offered a contract rate who want to verify whether the higher gross compensates for lost entitlements.
• Contractors evaluating employment offers — Existing ABN holders offered a permanent role who want to compare the net financial position after accounting for super, leave, and insurance.
• Employers setting contract rates — Hiring managers and HR teams determining a fair contractor day rate that equals their standard employee salary package.
• Accountants and bookkeepers — Tax professionals advising clients on the financial implications of changing their engagement structure for the 2025-26 financial year.

What Are the Tax Obligations for Contractors vs Employees?

Employees and contractors pay the same income tax rates under Australia's progressive tax brackets, but the method of collection, timing, and deduction opportunities differ significantly.

Employee Tax Obligations

Employers deduct income tax from each pay cycle through the "PAYG Withholding" system based on ATO tax tables. The employee's obligations are minimal: lodge a single annual tax return, claim limited work-related deductions, and pay the 2% Medicare levy (deducted automatically). The employer handles super (12% SG rate), workers compensation insurance, and payroll tax. Use the Take-Home Pay Calculator to see your exact after-tax income as an employee.

Contractor Tax Obligations

Contractors operating under an ABN manage their own taxation. Key obligations include:

1. PAYG instalments — quarterly income tax pre-payments to the ATO, calculated on estimated annual income.
2. GST registration — mandatory once annual turnover exceeds $75,000. The contractor charges clients 10% GST and remits it quarterly via a "Business Activity Statement" (BAS).
3. Medicare levy — 2% of taxable income, paid at tax time. The "Medicare Levy Surcharge" of 1%–1.5% applies to contractors earning above $93,000 without private hospital cover.
4. Superannuation — voluntary personal contributions are tax-deductible up to the $30,000 concessional cap for FY2025-26.
5. Annual tax return — includes a business schedule reporting all income, expenses, and deductions.

FY2025-26 Income Tax Brackets for Both

Both employees and contractors apply these identical tax brackets. The difference is that contractors reduce their assessable income through business expense deductions before tax is calculated. See the full breakdown in our Income Tax Calculator.

Which Is Better Financially: Contractor or Employee?

Employment is financially better at the same gross rate. A contractor needs to earn approximately 30–45% more than the equivalent employee salary to achieve the same total compensation value after accounting for super, leave, and insurance.

What Hidden Costs Do Contractors Face?

Contractors bear 6 additional costs that employees receive at no charge. These hidden costs reduce the contractor's effective hourly rate and total compensation value.

• Superannuation (12% SG) — Employer pays this in addition to base salary. Self-funding costs $12,000 on a $100,000 income.
• Annual leave (4 weeks) — Approx 7.6% of your yearly working value, equivalent to $7,600 on a $100,000 salary.
• Personal/sick leave (10 days) — Approx 3.8% of your yearly working value, equivalent to $3,800 on a $100,000 salary.
• Workers compensation insurance — Costs $500–$3,000 annually depending on industry and risk classification.
• Professional indemnity / public liability — Premiums range from $400–$2,500 per year for most professional services contractors.
• Accounting and software — Bookkeeping, BAS lodgment, and accounting software cost $1,500–$4,000 per year.

When Does Contracting Pay Off?

Contracting becomes financially advantageous when the contract rate exceeds the equivalent employee salary by at least 30%. Below that threshold, the value of lost entitlements typically outweighs the higher gross income.

What Are Common Mistakes When Comparing Contractor and Employee Pay?

The most common mistake is comparing gross rates directly without adjusting for the $25,000–$40,000 gap in hidden entitlements and costs. Five frequent errors distort the contractor vs employee calculation.

1. Ignoring superannuation — Employees receive 12% super on top of their salary. A contractor earning $100,000 who skips super misses $12,000 per year in retirement savings, compounding to over $400,000 across a 20-year career at average fund returns.
2. Forgetting leave entitlements — Four weeks of annual leave and 10 days of personal leave represent 11.4% of an employee's salary value. Contractors who work every billable day to match income risk burnout without accounting for unpaid downtime.
3. Overlooking GST obligations — Contractors earning above $75,000 must register for GST and charge clients 10%. The GST collected is not income — it belongs to the ATO. Spending GST revenue as personal income creates a debt at BAS time.
4. Underestimating admin costs — BAS lodgment, bookkeeping, insurance premiums, and software subscriptions cost $3,000–$6,000 annually. Many new contractors discover these costs only after their first BAS quarter.
5. Assuming "sham contracting" is risk-free — The ATO applies a multi-factor test to determine genuine contractor status. Employers face penalties of up to $16,500 per contravention under the Fair Work Act for incorrectly classifying employees as contractors.

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.

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.

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). From 1 July 2026 that is the shortfall, notional earnings at the general interest charge rate compounded daily, and an administrative uplift of up to 60%; the charge is now tax-deductible. For earnings paid up to 30 June 2026 the old rules apply — 10% nominal interest, $20 per employee per quarter, and no deduction.
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 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.
