Usually, an employer is required to split health insurance costs right down the middle, covering 50% of the employee’s monthly premium; however, different states and insurance companies have different minimum employer contribution levels. In the case of the 50/50 split, the employee is responsible for the remaining 50% of his or her premium as well as 100% of the premium for any dependents. It is up to the employer to decide whether or not to cover more than the minimum contribution. While completing an application with the insurance company of your choice, you will have the opportunity to specify your level of contribution for your employees and their dependents.
