Best Practices for Documenting Employee Benefit Plans

Proper Documentation of Employee Benefit Plans

Maintaining accurate documentation for employee benefit plans is an important compliance responsibility for employers. Most private-sector employers are subject to the Employee Retirement Income Security Act (ERISA), which establishes minimum standards for employer-sponsored benefits.

ERISA requires employers to maintain a formal written plan document and provide participants with a Summary Plan Description (SPD) that explains eligibility, benefits, and participant rights.

Employers that allow employees to pay for benefits through pre-tax payroll deductions must also comply with Internal Revenue Code Section 125. This rule requires a written Section 125 plan document to be adopted before the first day of the plan year.

Additional benefit arrangements—such as medical opt-out payments or dependent care flexible spending accounts (FSAs)—should also be properly documented.

Using a benefits administration platform like Employee Navigator can help employers manage plan documents, track employee elections, and distribute required communications.

ERISA Plan Documents and Wrap Documents

Insurance carriers and third-party administrators (TPAs) often provide benefit booklets that explain coverage and claims procedures. However, these materials typically do not include all provisions required under ERISA.

A wrap document supplements these materials by adding the required ERISA language. When used together, the plan documentation generally includes:

1. The carrier or TPA benefit booklet describing plan coverage and procedures
2. A wrap document providing required ERISA administrative provisions

Together, these materials form the official plan document and SPD. Both must be distributed to plan participants according to ERISA disclosure deadlines.

Section 125 Cafeteria Plan Documentation

Many employers allow employees to pay for benefits—such as medical, dental, or vision insurance—using pre-tax payroll deductions. These arrangements are commonly known as cafeteria plans, premium-only plans (POP), or premium conversion plans (PCP).

To preserve the tax advantages of these arrangements, employers must adopt a written Section 125 plan document before the beginning of the plan year. Without a compliant document, employee elections between taxable and non-taxable benefits may be treated as taxable income.

Medical Opt-Out Payments

Some employers offer a cash incentive for employees who decline coverage under the company’s health plan. These arrangements—often called opt-out payments or cash-in-lieu benefits—must generally be included in the employer’s Section 125 plan when employees can choose between health coverage and taxable compensation.

Employers offering opt-out incentives should confirm the arrangement is properly documented within their Section 125 plan.

Individual Coverage HRAs (ICHRAs)

Employers generally cannot reimburse employees for individual health insurance premiums without triggering penalties under the Affordable Care Act. However, an Individual Coverage Health Reimbursement Arrangement (ICHRA) allows employers to reimburse premiums for individual insurance or Medicare coverage on a tax-free basis.

ICHRAs allow employers to:

• Define eligible employee classes
• Set contribution amounts for each class
• Offer a traditional group plan to different employee groups

Because ICHRAs are considered group health plans under ERISA, they require a formal plan document and SPD.

Employers must also:

• Verify that employees maintain individual health coverage
• Allow employees to opt out annually
• Provide required notices explaining how the ICHRA interacts with premium tax credits

Dependent Care Flexible Spending Accounts

Dependent care FSAs allow employees to pay for eligible care expenses—such as childcare—with pre-tax funds. These benefits are authorized under Internal Revenue Code Section 129.

There is a dollar limit on the amount of your work-related expenses you can use to figure the credit. This limit is $3,000 if you had one qualifying person, or $6,000 if you had two or more qualifying persons.

Although dependent care FSAs are not subject to ERISA, employers must still maintain a written plan document and notify employees about eligibility and plan terms.

Annual Review of Plan Documents

Employers should review benefit plan documentation annually to ensure it reflects current plan design, administration practices, and regulatory requirements. This review is ideally completed before the start of each new plan year.

If plan changes occur, participants may need to receive:

• An updated Summary Plan Description (SPD)
• A Summary of Material Modifications (SMM)

Typical notice timelines include:

• 210 days after the end of the plan year for most updates
• 60 days after adoption for material reductions in benefits
• 60 days advance notice for certain mid-year changes affecting the Summary of Benefits and Coverage (SBC)

Providing timely communication helps employees understand their benefits and supports compliance with ERISA disclosure requirements.

Benefits administration systems such as Employee Navigator can assist employers by centralizing enrollment data, plan documents, and required communications.
