Contractor vs Employee Calculator for Australia

Contractors in Australia often appear cheaper because you avoid employer taxes, benefits, and overhead — but their hourly rates are typically 30–60% higher to compensate. For short-term or specialized work, contractors are usually more cost-effective. For ongoing roles exceeding 6–12 months, an employee often costs less total when you factor in the rate premium contractors charge.

Misclassifying an employee as a contractor in Australia can trigger back-payment of taxes, social contributions, benefits, and penalties — sometimes stretching back several years. Authorities typically examine factors like control over work schedule, exclusivity, integration into the organization, and who provides tools. The financial exposure can be severe: expect to owe the full employer-side taxes plus fines if audited.

Consider conversion when the engagement exceeds 6–12 months, the contractor works exclusively or primarily for you, you control how and when they work, or misclassification risk is increasing. Conversion also makes sense when the total contractor cost (higher rate x hours) exceeds what you would pay an employee with full benefits and overhead included.
