What Health Insurance Options Are Available for Centennial Accounting Firms?

For accounting and tax businesses in Centennial, the primary health insurance options typically fall into three categories:

Traditional Group Health Plans: These are plans purchased by your firm directly from an insurer, covering eligible employees and often their dependents. Your firm typically pays a portion of the premiums, and employees contribute the rest. These plans are familiar, offer consistent benefits across the team, and can be a strong recruitment tool.
Individual Coverage Health Reimbursement Arrangements (ICHRA): With an ICHRA, your firm provides tax-free funds that employees use to purchase their own individual health insurance plans on the Connect for Health Colorado marketplace. Your firm sets the contribution amount, and employees choose the plan that best fits their needs. This offers flexibility and predictable costs for the employer.
Individual Plans via Connect for Health Colorado: Employees can purchase individual plans directly from the state marketplace. Depending on their household income, they may qualify for premium tax credits (subsidies) to reduce their monthly costs. While not employer-sponsored, many small businesses use this as a fallback or complement to other strategies.

The choice depends on the size of your firm, your budget, and the level of flexibility you wish to offer your team.

Understanding Group Health Plan Requirements in Colorado

If your Centennial accounting or tax firm opts for a traditional group health plan, there are specific requirements to consider:

Minimum Participation: Most small group plans in Colorado require at least two full-time equivalent employees, not including the owner, to enroll. Owners can usually be counted if they have at least one W-2 employee.
Employer Contribution: Insurers typically require the employer to contribute a minimum percentage (often 50% or more) of the employee-only premium.
Enrollment Periods: Unlike individual plans, group plans don't strictly adhere to the annual Open Enrollment Period. You can generally establish a new group plan at any time of year.
Tax Advantages: Employer contributions to group health plans are tax-deductible for the business, and employee benefits are generally tax-free.

For firms with fewer than 50 full-time equivalent employees, the Small Business Health Options Program (SHOP) available through Connect for Health Colorado can offer additional benefits, including potential tax credits for employer contributions.

Navigating Individual Coverage Health Reimbursement Arrangements (ICHRA)

ICHRA offers a modern approach to employee benefits, particularly appealing to smaller accounting and tax firms in Centennial seeking cost control and employee choice. With an ICHRA, your firm sets a monthly allowance, and employees use this tax-free money to pay for health insurance premiums and sometimes other medical expenses they incur. Key advantages of an ICHRA for your firm:

Cost Control: Your firm commits to a fixed monthly contribution per employee, making budgeting predictable.
Flexibility for Employees: Employees choose any plan from Connect for Health Colorado that best suits their needs, including preferred doctors and hospitals like Hca-healthone DBA Swedish Medical Center or The Medical Center of Aurora & South Hospital.
Tax Efficiency: Employer contributions are tax-deductible, and employees receive the funds tax-free, provided they have qualifying health coverage.
No Minimum Participation: Unlike traditional group plans, ICHRA does not have minimum participation requirements, making it viable for very small teams.

This model effectively separates the employer's role in funding from the employee's choice of plan, offering a win-win for many small businesses.
