Who Counts as an Employee for a Group Plan in Colorado

Colorado does not answer this with a headcount. It answers it with a definition: an eligible employee is a full-time employee in a bona fide employer-employee relationship, and the statute then removes three groups from the term, one of them with an exception attached. Get the definition right and the count follows.

The term the Colorado band counts is a defined term

Colorado’s small employer test at C.R.S. § 10-16-102(61)(b)(II) counts eligible employees, not people on the payroll, and the state defines that term in its own subsection a few lines earlier. An owner who reads the band and stops has the ceiling without the rule that fills it.

Here is the definition in full, from the 2026 edition of the Colorado Revised Statutes. C.R.S. § 10-16-102(18)(a) reads:

(18) (a) “Eligible employee” means a full-time employee in a bona fide employer-employee relationship with an employer that has not been established for the purpose of obtaining a small group plan. The term does not include: (I) An employee who works on a temporary or substitute basis; (II) An individual and his or her spouse or partner in a civil union with respect to a trade or business, whether incorporated or unincorporated, that is wholly owned by the individual or by the individual and his or her spouse or partner in a civil union; or (III) A partner in a partnership and his or her spouse or partner in a civil union with respect to the partnership; except that a partner and his or her spouse or partner in a civil union may participate in a small group plan established to cover one or more eligible employees of the partnership who are not partners in the partnership.

Two things are doing work before the exclusions even start. The relationship has to be a bona fide employer-employee relationship, and the employer must not have been established for the purpose of obtaining a small group plan. A company formed to wrap a group around people who are not really its employees is outside the definition on the face of it.

The first two exclusions: temporary work, and the wholly owned business

The first limb is the shortest and the easiest to apply. C.R.S. § 10-16-102(18)(a)(I) takes out an employee who works on a temporary or substitute basis. That is a statement about the basis of the work rather than about hours, a job title or a payroll classification, so the question to ask about a seasonal or fill-in worker is what basis they were engaged on.

The second limb is the one most often repeated wrongly. C.R.S. § 10-16-102(18)(a)(II) excludes an individual and that individual’s spouse or civil union partner with respect to a trade or business, whether incorporated or unincorporated, that is wholly owned by the individual or by the couple.

Read the scope rather than the gist. The limb is anchored on wholly owned. It is not a general proposition that owners never count as employees in Colorado. Where you land depends on how the business is actually held, which is worth establishing before a census goes anywhere near a carrier — it is one of the first things covered when setting up a first group health plan.

Partners, and the exception that inverts the limb

The third limb is where a summary does the most damage. C.R.S. § 10-16-102(18)(a)(III) excludes a partner in a partnership and that partner’s spouse or civil union partner with respect to the partnership — and then, in the same subsection, says a partner and their spouse or civil union partner may participate in a small group plan established to cover one or more eligible employees of the partnership who are not partners in the partnership.

That second half changes the practical answer completely. It does not say a partner can never be covered. It says the plan has to have been established to cover non-partner eligible employees of the partnership, and partners can then participate in it. Quote the exception or quote neither half, because the limb on its own reads like a flat bar and is not one.

A family member on the payroll gets a pay test, not a relationship test

Colorado wrote a specific rule for the case every family business runs into. C.R.S. § 10-16-102(18)(b) provides:

(b) Notwithstanding any provision of law to the contrary, an eligible employee of a small employer who could also be considered a dependent of the small employer must receive taxable income from the small employer in an amount equivalent to minimum wage for working full-time on a permanent basis in order to be considered an employee of the small employer.

The test is what the person is actually paid and on what footing, not how they are related. A child or spouse who is genuinely employed full-time on a permanent basis and paid accordingly is being measured by that standard; someone carried on the books is not.

What full-time means here is the employer’s own standard

The definition opens on the words full-time employee, which naturally raises the question of where that line sits. Colorado’s answer is affirmative and it is not a number the state supplies. C.R.S. § 10-16-102(18)(c) provides:

(c) Nothing in this subsection (18) limits the employer’s traditional ability to set valid and acceptable standards for employee eligibility based on the terms and conditions of employment, including a minimum weekly work requirement in excess of thirty hours and eligibility based upon salaried versus hourly workers and management versus nonmanagement employees.

Colorado preserves the employer’s own eligibility standards and names three examples of what they can be built on: a minimum weekly work requirement, salaried against hourly, and management against nonmanagement. Note what that subsection is describing — a floor the employer may set above, per C.R.S. § 10-16-102(18)(c), rather than a state definition of full-time work. Your own eligibility rules are a real design choice and they belong in the plan document, not in a conversation at renewal.

Defining an employee and counting employees are two different questions

Here is a genuine tension in Colorado law, and the right thing to do with it is state it rather than settle it. The definition above is built on a full-time employee. But the counting rule sits elsewhere. C.R.S. § 10-16-102(61)(c) provides:

(c) For purposes of determining whether an employer is a “small employer”, the number of eligible employees is calculated using the method set forth in 26 U.S.C. sec. 4980h (c)(2)(E).

The federal method named there — 26 U.S.C. § 4980H — exists to fold part-time hours into equivalents. So one subsection defines the eligible employee as full-time and a neighboring subsection directs the count to a method that reaches past full-time work, and Colorado does not tell you how to read them together.

Anyone who tells you flatly that part-timers do or do not count in Colorado is filling that gap themselves. The accurate position is the one the statute supports: C.R.S. § 10-16-102(18)(a) defines the term, C.R.S. § 10-16-102(61)(c) directs the count to the federal method, and the carrier applies both to your census. Put the facts in front of the carrier and let the answer come back in writing.

Two companies with one owner are one employer

If you hold more than one business, the count does not start over for each. C.R.S. § 10-16-102(61)(f) provides:

(f) The following employers are single employers for purposes of determining the number of employees: (I) A person or entity that is a single employer pursuant to 26 U.S.C. sec. 414 (b), (c), (m), or (o); and (II) An employer and any predecessor employer.

The first limb is a federal common-control cross-reference and it is the two-companies-one-owner case. The second is Colorado’s own addition and it deserves a sentence of its own: an employer and any predecessor employer are one employer. A business that was reorganized, restructured or bought does not get a fresh count on the strength of the new entity.

A business that was not there last quarter

New employers are measured forward instead of backward. C.R.S. § 10-16-102(61)(e) provides:

(e) In the case of an employer that was not in existence throughout the preceding calendar quarter, the determination of whether the employer is a small employer is based on the average number of employees that the employer is reasonably expected to employ on business days in the current calendar year.

Note the units, because the statute does not smooth them and neither should anyone explaining it. The trigger is not having existed throughout the preceding calendar quarter; the measurement is an expectation across the current calendar year. A young Colorado business is being asked for a reasonable expectation, which means it should be able to say where the expectation came from.

An employee whose hours are cut

One more provision changes who stays on a plan once you have one. C.R.S. § 10-16-108(2) carries the subsection heading “Group policies and group service contracts - reduction in hours of work” and provides:

Every group policy or group service contract delivered or issued for delivery in this state by an insurer subject to part 2 of this article or by an entity subject to part 3 or 4 of this article that covers full-time employees working forty or more hours per week shall contain a provision that the policyholder may elect to contract with the insurer or other entity to continue the policy or contract under the same conditions and for the same premium for the employees and their dependents even if the policyholder or employer reduces the working hours of the employees to less than thirty hours per week, if the following conditions are met: (a) The covered employee is employed as a full-time employee of the policyholder or employer and is insured under the group policy or group service contract… immediately prior to the reduction in working hours; (b) The policyholder has imposed the reduction in working hours due to economic conditions or due to the employee’s injury, disability, or chronic health conditions; and (c) The policyholder intends to restore the employee to a full forty-hour work schedule as soon as economic conditions improve or as soon as the employee is able to return to full-time work.

All three conditions travel together. The provision is an election the policyholder makes, it is conditioned on the reason for the reduction, and limb (c) adds an intention to restore the schedule that is easy to leave out of a summary and is part of the rule. The section it sits in is headed Continuation privileges, which reads like post-termination coverage; subsection (2) is about someone who is still employed at reduced hours, so cite the subsection.

Dependents are defined separately

Finally, the people who come onto the plan alongside the employee are their own defined term. C.R.S. § 10-16-102(17) provides:

(17) “Dependent” means a spouse, a partner in a civil union, an unmarried child under nineteen years of age, an unmarried child who is a full-time student under twenty-four years of age and who is financially dependent upon the parent, and an unmarried child of any age who is medically certified as disabled and dependent upon the parent. “Dependent” includes a designated beneficiary, as defined in section 15-22-103 (1), C.R.S., if an employer elects to cover a designated beneficiary as a dependent.

Dependents are not eligible employees and they do not enter the small employer count. They matter for a different reason: whether you offer dependent coverage, and what you contribute toward it, is one of the levers that decides what a Colorado group health plan costs you and what it costs your staff. The Colorado regulator, the statutory definitions and the state mandates that sit behind all of this are collected on the Colorado page.

The practical order is the same every time. Establish how the business is held, apply C.R.S. § 10-16-102(18)(a) to each person you were about to count, hand the carrier the facts on the full-time question rather than a conclusion, and let the count come back from the people who have to stand behind it.
