If you’re a small business owner who recently launched a group health plan for your team, you may have assumed your only responsibility is signing the carrier contract and sending monthly invoices. Many small employers confuse routine business decisions about health benefits with fiduciary acts, which carry legal and financial liability if handled incorrectly. This guide clarifies which actions trigger fiduciary duties, gives you a usable checklist to stay compliant, and breaks down common misconceptions about what you are and are not responsible for.
Two options people mix up
The two most commonly confused roles for small business owners running a health plan are settlor and fiduciary, each with very different requirements. Settlor functions are rooted in your role as a business owner making decisions about what benefits to offer as part of employee compensation. These are choices you can make based purely on your company’s budget and staffing goals, with no requirement to prioritize employee interests over business needs. Fiduciary functions, by contrast, are tied to your role as the plan administrator of a regulated employee benefit plan. When you act in this role, you are legally required to act solely in the interest of plan participants and their beneficiaries, with the exclusive purpose of providing benefits and covering reasonable plan expenses. Many owners incorrectly assume all plan-related decisions fall under the settlor umbrella, leaving them exposed to risk when operational decisions prioritize company cost savings over employee benefits.
Comparison table
The table below clarifies which common health plan actions are settlor decisions (no fiduciary duty applies) and which trigger fiduciary obligations:
| Action Category | Settlor Action (No Fiduciary Duty Applies) | Fiduciary Action (Fiduciary Duty Applies) |
|---|---|---|
| Plan design | Deciding whether to offer a health plan, choosing to cover only full-time employees, setting dependent eligibility rules | Confirming the plan follows all stated benefits in the Summary of Benefits and Coverage (SBC), ensuring eligibility rules are applied consistently to all employees |
| Carrier selection | Narrowing down plan options that fit your company’s total benefits budget | Reviewing carrier fees, network adequacy, and claims processing speed to select the option that offers the best reasonable value for plan participants |
| Employee contributions | Setting the percentage of premiums you will cover vs. the percentage employees will pay | Ensuring employee premium deductions are accurate, deposited to the carrier on time, and never used for general business expenses |
| Claims support | Deciding whether to offer a dedicated HR point person for benefits questions | Following up on denied claims to confirm the carrier’s decision aligns with the published SBC, providing employees with all required appeal information |
| Plan communication | Deciding how to announce open enrollment to your team | Distributing required federal and state disclosures (including SBCs, summary plan descriptions, and special enrollment notices) to all eligible employees on time |
Fiduciary Duty Compliance Checklist for Small Employers
Use this checklist to track routine operational tasks to meet your fiduciary obligations:
- [ ] All operational health plan decisions prioritize plan participants’ interests over company cost savings, with written documentation of tradeoffs considered
- [ ] I have retained copies of all bids, quotes, and service reviews from carrier or third-party administrator (TPA) selection processes for at least 6 years
- [ ] I distribute the required SBC and open enrollment materials to all eligible employees at least 30 days before the start of each plan year
- [ ] I have a documented process for employees to submit benefits questions and appeal denied claims, with clear timelines for response
- [ ] All employee payroll deductions for health premiums are deposited to the carrier or TPA within the timeline required by your state insurance regulator
- [ ] I review carrier and TPA invoices quarterly to confirm no unauthorized fees are being charged to the plan or deducted from employee pay
- [ ] I do not use any plan assets (including employee contributions, carrier reimbursements, or plan rebates) for general business operating costs
- [ ] I conduct an annual review of carrier and TPA performance to confirm they are meeting the terms of their contract with your company
Illustrative example
Illustrative example: A 14-person independent retail shop owner decides to offer health benefits for the first time to reduce employee turnover. They choose to cover 60% of employee premiums as part of their compensation package, which is a settlor decision, so no fiduciary duty applies to this choice. When selecting a carrier, the owner gets four quotes, with two falling within their allocated benefits budget. The first option has a broad local network that includes 90% of the primary care providers the team already uses, with a $25 copay for primary care visits. The second is 12% cheaper for the company, but has a narrow network that excludes 70% of the team’s current providers, with a $75 primary care copay.
If the owner chooses the cheaper option without disclosing the network and cost tradeoffs to the team, and without documenting why the lower-cost option is a reasonable value, they could be found to have breached their fiduciary duty. If they share both options with the team, explain the cost differences and network gaps, survey employees to understand their priorities, and document their final decision based on that feedback, they are meeting their fiduciary obligations. Later in the year, if an employee’s claim for a routine checkup is denied because the carrier incorrectly coded the visit as out of network, the owner is required to follow up with the carrier to confirm the denial is consistent with the SBC, and provide the employee with the required appeal paperwork. Failing to do that could also count as a fiduciary breach.
Limits and exceptions
There are key limits to fiduciary duties for small employers that reduce compliance burden for most teams. First, you do not have to select the most expensive plan option, or the plan with the broadest possible network, to meet your fiduciary duties. You only need to select a plan that offers reasonable value for the cost, and document all the factors you considered when making your selection.
Second, you can hire a licensed fiduciary broker or TPA to handle most operational plan tasks, but you cannot outsource all fiduciary liability. You are still required to monitor the third party’s performance annually to confirm they are meeting their contractual obligations and acting in participants’ best interests.
Third, small plans with fewer than 100 employees are exempt from some federal audit requirements that apply to large group plans, but core fiduciary duty rules still apply unless your state specifies otherwise. Confirm any state-specific exemptions with your state insurance exchange or local insurance regulator.
Fourth, you are not responsible for medical treatment decisions made by employees’ providers, or for claims denials that are fully consistent with the terms of the published SBC, as long as you provide employees with all required information to file an appeal on their own. If your company is the only one contributing to the plan (i.e., employees pay no premiums), some fiduciary rules around asset management are less strict, but you still have a duty to ensure plan benefits are administered as advertised.
Bottom line
Fiduciary duties for small company health plans are often less onerous than many employers assume, and most compliance requirements can be met with consistent documentation and transparent decision-making. The biggest risk of breach comes from mixing up settlor business decisions and fiduciary operational decisions, or failing to track decisions around carrier selection and plan administration.
