Tax Deductions: Premiums paid by the employer are generally tax-deductible business expenses.
Broader Networks: Often provide access to a wider range of doctors and hospitals compared to some individual plans.
Employee Retention: A valuable benefit that helps attract and retain skilled professionals in the competitive accounting and tax industry.

Premium Tax Credits: Individuals and families with incomes between 100% and 400% of the Federal Poverty Level (FPL) may qualify for significant subsidies to reduce monthly premiums. In Colorado, Medicaid expansion means subsidies start at 138% FPL.
Choice of Plans: Connect for Health Colorado offers a variety of plans (Bronze, Silver, Gold, Platinum) with different cost-sharing structures.
Catastrophic Plans: Available for individuals under 30 or those with a hardship exemption, offering basic coverage with high deductibles.

Colorado expanded Medicaid in 2014, known as Health First Colorado. Adults with incomes up to 138% FPL may qualify for comprehensive, low-cost or no-cost health coverage. For a single individual in 2026, 138% FPL would be approximately $22,000 annually. Pregnant women can qualify for coverage through Child Health Plan Plus (CHP+) up to 195% FPL, and children up to 260% FPL.

Evaluating Plan Tiers and Cost-Sharing

Whether through a small group plan or individual options, understanding the metal tiers (Bronze, Silver, Gold, Platinum) is crucial:

Bronze Plans: Lowest premiums, highest out-of-pocket costs (deductibles, copays). Best for healthy individuals who anticipate minimal medical care.
Silver Plans: Moderate premiums and out-of-pocket costs. Crucially, if employees qualify for cost-sharing reductions (CSDs) based on income (up to 250% FPL), Silver plans offer enhanced benefits and lower deductibles.
Gold Plans: Higher premiums, lower out-of-pocket costs. Good for those who expect to use medical services regularly.
Platinum Plans: Highest premiums, lowest out-of-pocket costs. Designed for individuals with extensive medical needs.

Colorado's marketplace, Connect for Health Colorado, offers PPO plans in addition to HMO and EPO plans. This means that small business owners and their employees have a broader range of network structures to consider, including those that offer more flexibility in choosing out-of-network providers.
