An employer's premium is calculated twice during each policy period. The initial premium (called the premium estimate) is calculated at the beginning of the policy period. It is based on an estimate of wages that an employer is likely to pay during the policy period.
The final premium (called the hindsight premium) is calculated at the end of the policy period. It is calculated using the actual amount of wages paid by the employer during the policy period.
If the hindsight premium is higher than the initial premium, the employer will need to pay the difference to their Scheme Agent. If the hindsight premium is lower than the initial premium, the employer’s Scheme Agent will repay or credit the employer any overpayment.
Basic tariff premium
An employer’s basic tariff premium is calculated by multiplying their wages by the WorkCover Industry Classification (WIC) rate of the applicable industry class. Where the employer has a multi-tariff policy, this formula is repeated for each applicable industry class, and the outcomes added together to produce the total basic tariff premium.
For a small number of industry classes, basic tariff premium rates are expressed as a per capita rate (eg. professional sport) or a per plate rate (eg. taxis and hire cars).
The minimum premium is $175, even if the calculation produces a lower amount.
Estimating premiums
Employers can easily get an estimate of their workers compensation premium using WorkCover’s online premium estimator.
The premium estimator allows a new business, or an existing business looking to diversify or expand, to calculate what happens to their workers compensation premiums if they:
By selecting the business activity that best describes the business from the list, employers can gain assurance they are using the correct WorkCover Industry Classification.
Employers can also vary their details to compare the impact of different business scenarios and print or save a copy of the premium estimate.
