Small group health insurance is a type of health insurance policy that is designed for small businesses or groups with fewer than 50 employees. There are several reasons why a small business owner may choose to purchase small group health insurance for their employees:

1. Cost savings: Small group health insurance policies are often more affordable than individual health insurance plans. This is because the risk is spread across a larger pool of people, which can lead to lower premiums.

2. Attract and retain employees: Offering health insurance as part of an employee benefits package can help attract and retain top talent. This is especially important for small businesses that are competing with larger companies for skilled workers.

3. Compliance with the law: The Affordable Care Act (ACA) requires businesses with 50 or more full-time employees to provide health insurance to their employees. While small businesses with fewer than 50 employees are not required to provide health insurance, offering it can help businesses stay in compliance with the law and avoid penalties.

4. Improved employee health and productivity: Access to healthcare can help employees stay healthy and productive. When employees have access to preventive care, they are less likely to miss work due to illness and may be more productive when they are at work.

Overall, small group health insurance can be a valuable investment for small businesses that want to offer competitive benefits packages, stay in compliance with the law, and promote the health and well-being of their employees.
