Understanding Small Group Health Insurance for Your Firm

Small group health insurance plans are designed for businesses with 1 to 50 employees (in Colorado, this typically means 2 to 50 employees, excluding the owner). These plans are distinct from individual marketplace plans and offer several advantages, including shared costs between employer and employee, and often a wider range of network options. For accounting and tax firms, offering health benefits can significantly enhance employee satisfaction and reduce turnover, especially in a competitive market like Denver.

What are the Eligibility Requirements for Small Businesses in Colorado?

To qualify for a small group health plan in Colorado, your accounting or tax firm must generally meet a few key criteria:

Employee Count: You must have at least one full-time equivalent employee in addition to the owner (or the owner's spouse). Some carriers may require a minimum of two non-owner employees.
Business Location: Your business must be located in Colorado and operate legally within the state.
Contribution: Most carriers require the employer to contribute a minimum percentage (often 50%) towards employee premiums.
Participation: A certain percentage of eligible employees (typically 70%) must enroll in the plan, excluding those who waive coverage due to having other qualified insurance (e.g., through a spouse's employer).

Meeting these requirements allows your firm to access the small group market, which includes plans offered through Connect for Health Colorado's Small Business Health Options Program (SHOP) Marketplace.

Types of Health Plans Available in Denver County

Small businesses in Denver County have access to various plan types, ensuring flexibility to match your firm's budget and your employees' needs. In Colorado, PPO plans are available on-exchange, giving businesses more choice than in some other states.

HMO (Health Maintenance Organization) Plans

HMO plans typically have lower premiums and out-of-pocket costs but require members to choose a primary care provider (PCP) within the plan's network. Referrals from the PCP are usually needed to see specialists, except in emergencies. These plans emphasize coordinated care within a specific network.

EPO (Exclusive Provider Organization) Plans

EPO plans offer a bit more flexibility than HMOs, as you typically don't need a PCP referral to see a specialist. However, like HMOs, they only cover services from doctors, specialists, or hospitals within the plan's network, except in emergencies. Out-of-network care is generally not covered.

PPO (Preferred Provider Organization) Plans

PPO plans offer the most flexibility, allowing members to see any doctor or specialist, in-network or out-of-network, without a referral. While out-of-network care is covered, it comes at a higher cost. PPO plans typically have higher premiums and deductibles compared to HMO or EPO plans, but they provide a wider choice of providers. In Denver County, PPO plans are offered by carriers like Denver Health Medical Plan and HMO Colorado, among others, on Connect for Health Colorado.

Financial Assistance for Small Businesses: The Small Business Health Care Tax Credit

The Affordable Care Act (ACA) includes provisions to help small businesses afford health insurance for their employees. The Small Business Health Care Tax Credit is designed for small employers who cover a significant portion of their employees' health insurance premiums.

Who Qualifies for the Tax Credit?

To be eligible for the tax credit, your accounting or tax firm must meet specific criteria:

Fewer than 25 Full-Time Equivalent (FTE) Employees: This is calculated based on total hours worked by all employees.
Average Annual Wages: The average annual wages of your employees must be less than approximately $58,000 (this figure adjusts annually).
Employer Contribution: You must pay at least 50% of your employees' premium costs.
SHOP Marketplace Enrollment: You must purchase coverage through the Small Business Health Options Program (SHOP) Marketplace via Connect for Health Colorado.

The maximum credit is 50% of the employer's contribution to premiums for small businesses and 35% for tax-exempt organizations. The credit is available for two consecutive tax years. Utilizing this credit can significantly reduce the cost of providing health benefits to your team.
