What Are Your Small Business Health Insurance Options in Centennial?

Small business plumbing contractors in Centennial have two primary avenues for providing health benefits: traditional group health insurance and Individual Coverage Health Reimbursement Arrangements (ICHRA). Both offer distinct advantages depending on your company's size, budget, and desired level of administrative involvement.

Traditional Group Health Plans: These plans cover multiple employees under a single policy, with the employer typically contributing a percentage of the premium. They are often attractive for their comprehensive benefits and straightforward administration once set up. In Centennial, small group plans are available through the private market or sometimes via the Connect for Health Colorado marketplace for employers.

Individual Coverage Health Reimbursement Arrangements (ICHRA): An ICHRA allows employers to reimburse employees tax-free for individual health insurance premiums and other qualified medical expenses. Employees purchase their own plans from Connect for Health Colorado or directly from carriers. This option offers greater flexibility for employees to choose plans that best fit their individual needs, and it can simplify administration for the employer by setting a defined contribution amount.

Eligibility for Small Group Health Plans in Colorado

To offer a small group health plan in Centennial, your plumbing business must meet specific criteria set by Colorado law and insurance carriers. These requirements ensure a viable risk pool and fair access to coverage.

Minimum Employee Count: Generally, you must have at least two full-time employees, not including the owner's spouse. Some carriers may allow a single owner-employee if they have at least one other non-owner, non-spouse employee.
Employee Participation: Most carriers require a minimum of 70% of eligible employees to enroll in the plan. Employees who already have other qualifying coverage (e.g., through a spouse's job, Medicare, or Health First Colorado) are typically exempt from this calculation.
Employer Contribution: Employers usually must contribute a minimum percentage towards employee premiums, often 50% or more, though this can vary by carrier and plan.
Business Location: Your business must be located within the service area of the chosen health insurance carrier, which for Centennial means within Colorado Rating Area 1.

Understanding Tax Advantages for Plumbing Businesses

Offering health insurance to your plumbing team in Centennial provides significant tax benefits for your business. These incentives can help offset the cost of providing coverage.

Employer Deductions: Premiums paid by your plumbing business for employee health insurance are 100% tax-deductible as an ordinary and necessary business expense. This applies to both traditional group plans and amounts reimbursed through an ICHRA.

Employee Tax Exclusion: For employees, the value of employer-provided health insurance benefits (including ICHRA reimbursements) is excluded from their taxable income. This means they receive the benefit tax-free, increasing the real value of their compensation.

Small Business Health Care Tax Credit: If your plumbing business has fewer than 25 full-time equivalent employees and you contribute at least 50% of the premium cost, you may qualify for the Small Business Health Care Tax Credit. This credit can cover up to 50% of the employer's contribution towards premiums, significantly reducing your net cost. Eligibility and credit amount depend on average employee wages and the number of full-time equivalent employees.

Centennial, located in Arapahoe County, is part of Colorado Rating Area 1, which covers Adams, Arapahoe, Broomfield, Denver, Douglas, and Jefferson counties. In 2026, 6 carriers offer marketplace plans in Rating Area 1, providing a range of choices for small businesses. These carriers offer various plan types, including HMO, EPO, and PPO options.

Navigating Medicaid and CHP+ for Your Employees

It's important for small business owners in Centennial to understand that some employees or their dependents may qualify for public health programs like Health First Colorado (Colorado's Medicaid program) or Child Health Plan Plus (CHP+). Colorado expanded Medicaid in 2014, meaning adults with incomes up to 138% of the Federal Poverty Level (FPL) may qualify for Medicaid at little to no cost.

Additionally, Colorado's CHP+ covers pregnant women with incomes up to 195% FPL for comprehensive prenatal, delivery, and postpartum care. CHP+ also extends coverage to children in households with incomes up to 260% FPL. Employees can apply for these programs through Colorado PEAK (colorado.gov/PEAK). Understanding these options ensures that all your employees have access to necessary healthcare, regardless of their income level or your business's benefits offerings.

Arapahoe County, with a population of 659,844 and a median household income of $101,087 per U.S. Census Bureau ACS 2024 5-year estimates, has an uninsured rate of 9.3%. Centennial itself has a lower uninsured rate of 3.8% among its 108,201 residents, with a median income of $131,928. This means that while many residents have coverage, understanding all available options, including public programs, remains essential for comprehensive planning.

Making the Right Decision for Your Centennial Plumbing Business

Choosing the best health insurance solution for your plumbing business in Centennial depends on several factors, including your budget, the size of your team, and your administrative capacity.

For Traditional Group Plans: If you value a single, comprehensive plan for your team and are comfortable with a defined employer contribution, a group plan might be ideal. Consider the network options from carriers like Kaiser Permanente or United Healthcare to ensure your employees have access to preferred local providers.

For ICHRA: If flexibility for employees and predictable costs for your business are priorities, an ICHRA could be a better fit. This allows employees to select plans from Connect for Health Colorado, potentially accessing subsidies based on their household income, while you manage a set reimbursement amount.

Regardless of the path you choose, consulting with a licensed health insurance producer can simplify the process. They can help you compare plans, understand eligibility rules, and navigate the tax implications specific to your plumbing business in Centennial. Their expertise ensures you select a plan that meets both your business needs and your employees' healthcare requirements.
