What is the primary benefit of an employer purchasing a group health policy for employees?

The primary benefit of an employer purchasing a group health policy for employees is that it provides tax deductions for the employer. When an employer offers health insurance, they can deduct the cost of the premiums paid for group health policies from their taxable income. This can significantly reduce the employer's tax burden while also offering an important benefit to employees, contributing to employee satisfaction and retention.

In this context, although lower premiums for employees could be a favorable outcome of a group policy, the main advantage lies in the financial benefit that the employer receives through tax deductions. Guaranteed issuance of policies and universal coverage for all employees are also important factors in group health insurance, but they do not directly relate to the primary financial advantage for the employer.
