Documenting employee benefit plans is a key compliance step that can be easily overlooked. Most private-sector employers must follow ERISA, which requires welfare benefit plans to have a written plan document and a summary plan description (SPD) for participants. Employers that allow pre-tax benefit contributions under Section 125 must also adopt a written Section 125 plan document before the plan year begins and ensure other benefits, such as medical opt-out payments and dependent care FSAs, are documented. These requirements are ongoing, plan documents and employee communications should be reviewed at least annually, and any significant changes must be communicated to employees promptly.
Use a “Wrap Document” to Comply with ERISA’s Requirements for Plan Documents/SPDs
ERISA Requirements
ERISA requires private-sector employers to have a formal plan document and SPD for each employee benefit plan, carrier or third-party administrator (TPA) materials alone are not enough. While ERISA does not impose a direct penalty for missing documents, the risks are significant: up to $110 per day for failing to provide an SPD within 30 days of a participant’s request, weaker legal protection in benefit disputes, and increased scrutiny or enforcement if the Department of Labor (DOL) audits your plan. The DOL may also assess up to $195 per day (capped per request) if plan documents are not provided upon request.
Wrap Document
Many carrier or TPA booklets do not include all of the ERISA-required language for a plan document or SPD. A wrap document is a simple, cost‑effective way to close those gaps. It “wraps around” the existing benefit booklet, incorporates it by reference, and adds the missing ERISA provisions. Together, the carrier/TPA booklet and the wrap SPD form the complete ERISA plan document, and both must be distributed to participants on time to stay compliant.
Adopt a Section 125 Plan Document Before Allowing Pre-tax Contributions
Code Section 125 lets employers offer a “cafeteria plan” so employees can pay for certain benefits like medical, dental, and vision on a pre-tax basis, increasing their take-home pay. To keep these savings tax-advantaged, the plan must follow IRS rules and be set out in a written document adopted before the plan year begins. If there is no compliant written plan, the IRS treats employees’ pre-tax elections as taxable income.
Include Any Medical Opt-out Payments Under the Section 125 Plan Document
Some employers offer “opt-out” or “cash in lieu” payments to employees who waive the group health plan, a strategy that can reduce costs while providing taxable cash to staff. Because employees are choosing between health coverage and taxable pay, these opt-out incentives must be offered through a Section 125 plan to protect the tax treatment of the health benefit. If you provide opt-out payments, be sure your Section 125 plan document is updated to include them.
Adopt an ICHRA to Reimburse Individual Insurance Premiums
Under the Affordable Care Act (ACA), employers generally may not reimburse employees for individual health insurance premiums without triggering excise taxes. An important exception is the Individual Coverage HRA (ICHRA), which lets employers reimburse individual and Medicare premiums on a tax-free basis for defined classes of employees.
Because an ICHRA is an ERISA group health plan, it must have a formal plan document, SPD, annual notice, proof of individual coverage, and an opt-out option each year. Employers can offer an ICHRA alongside a traditional group health plan, but not as a choice for the same employee. If the ICHRA does not cover the full premium, employees may be allowed to pay the balance pre-tax through a Section 125 plan but only for policies purchased outside the ACA Exchange.
Remember: Dependent Care FSAs Require a Plan Document and Employee Notification
Code Section 129 allows employers to offer dependent care FSAs so employees can pay for eligible child and dependent care on a tax-free basis, typically through pre-tax payroll contributions under a Section 125 plan. Beginning January 1, 2026, employees may contribute up to $7,500 per year ($3,750 if married filing separately).
Benefits are nontaxable when used for qualifying dependents, such as a child under age 13, so the employee (and spouse, if applicable) can work. While dependent care FSAs are not subject to ERISA, employers must still have a written plan document that meets Code Sections 129 and 125 and provides employees with clear notice of the plan and its terms.
Reviewing and Updating Plan Documents Each Year for Changes
To stay compliant and protected, employers should review their welfare plan documents at least once a year, ideally before the new plan year, so updates to plan design or administration are accurately reflected. Outdated documents can create significant risk in a benefits dispute or DOL audit.
When plan terms change, employers must also update employees. Material changes should be shared through an updated SPD or a Summary of Material Modifications (SMM) within required deadlines (as soon as possible is best). For mid-year changes that affect the Summary of Benefits and Coverage (SBC), employers must provide at least 60 days’ advance notice, using either an updated SBC or an SMM.
