WCB rates are generally set using an employer's previous years' claims experience. Because new employers don't have claims experience to factor into their rate, they receive the new employer rate identified for their industry classification.
New employers will continue to receive the new employer rate each year until their own claims experience can be used to calculate their rate. An employer may receive the new employer rate for up to three years. The new employer rates are updated on our website each year.
Once an employer has established two or more years of actual payroll information, they are assigned an employer size: small, medium or large, as well as a rate range that is associated with the size category.
