Summary Plan Description: What It Means for Employers

What it means in practice

What the term means. Section 102(a) of ERISA (29 U.S.C. 1022) says an SPD must be "written in a manner calculated to be understood by the average plan participant" and be "sufficiently accurate and comprehensive" to tell participants and beneficiaries their rights and obligations under the plan. It summarizes the plan document rather than replacing it. DOL calls the SPD "an important document that tells participants what the plan provides and how it operates," and says the plan administrator must provide it free of charge. Nearly every ERISA plan needs one, including retirement plans such as a 401(k) plan and welfare plans such as group health, disability and life insurance that make up most employee benefits packages.

Who must provide it and who receives it. The duty belongs to the plan administrator, which the SPD must name along with its business address and phone number. Under 29 CFR 2520.104b-2, the administrator furnishes the SPD and the statement of ERISA rights to each participant covered under the plan and to each beneficiary receiving benefits under a pension plan.

Which plans are covered. Title I of ERISA applies to benefit plans set up by employers engaged in commerce. Section 4(b) (29 U.S.C. 1003(b)) excludes governmental plans, church plans that have not elected coverage, plans maintained solely to comply with workers' compensation, unemployment or disability insurance laws, certain plans outside the United States, and unfunded excess benefit plans. A 403(b) plan run by a state or local government employer for its employees is therefore outside the federal SPD rule.

What it must contain. 29 CFR 2520.102-3 lists the required items. They include the plan name, employer, EIN and plan number; the type of plan and administration; the administrator, agent for service of legal process and trustees; eligibility rules and benefits; circumstances that can lead to loss, denial, forfeiture or reduction of benefits; amendment and termination rights; contribution sources and funding; the plan year end; claims procedures; and the statement of ERISA rights. Pension plans add normal retirement age, vesting and service rules, joint and survivor benefits, QDRO procedures and whether PBGC insurance applies. The SPD must reflect the plan as of a date no earlier than 120 days before it is disclosed.

Extra content for group health plans. A group health plan SPD must also describe cost sharing (premiums, deductibles, coinsurance and copays), annual or lifetime limits, preventive services, prescription drug coverage, network and out-of-network rules, emergency care conditions, preauthorization and utilization review, QMCSO procedures, COBRA continuation rights, and the federal 48-hour and 96-hour hospital stay rules for childbirth. If a health insurance issuer finances or administers the plan, the SPD must name the issuer and say to what extent benefits are guaranteed by insurance. Provider lists and claims procedures may be separate documents if the SPD says they are furnished automatically and without charge.

Style and format. Under 29 CFR 2520.102-2, the administrator should consider participants' comprehension and education level, which usually means less jargon, shorter sentences, examples and a table of contents. Limitations and exclusions must not be minimized or made obscure, and must be shown with captions and type no less prominent than those used to describe benefits.

Foreign-language assistance. The same regulation requires a notice in a non-English language, offering help, when a plan with fewer than 100 participants at the start of the plan year has 25% or more participants literate only in that same language, or when a plan with 100 or more participants has the lesser of 500 participants or 10% of all participants literate only in the same language. The SPD can stay in English; the notice and the help must be in that language.

Updated SPDs and summaries of material modifications. Section 104(b)(1) of ERISA requires an updated SPD integrating amendments every fifth year, and an SPD every tenth year even without amendments; the regulation sets the due date at 210 days after the end of the relevant plan year. Between updates, a summary of material modifications describes plan changes and changes to required SPD information. Under 29 CFR 2520.104b-3 it is due 210 days after the close of the plan year in which the change was adopted, even if the change applies retroactively or takes effect later. An SMM is not needed if the change is rescinded before taking effect, or if a timely updated SPD already describes it.

Faster notice for group health cuts. A group health plan must furnish a summary of any material reduction in covered services or benefits within 60 days after the change is adopted. Reductions include eliminating or reducing benefits, raising premiums, deductibles, coinsurance or copays, and adding conditions such as preauthorization. A plan that sends participants plan information at regular intervals of 90 days or less may use that system instead.

How to deliver it. 29 CFR 2520.104b-1(b) requires measures reasonably calculated to ensure actual receipt. Handing the SPD to employees at the worksite is acceptable; first-class mail works; simply leaving copies in a break room does not.

Electronic delivery. Under the 2002 safe harbor in 29 CFR 2520.104b-1(c), an SPD may go electronically to employees who can access documents where they work and for whom using the employer's electronic systems is an integral part of their duties, or to others who affirmatively consent after receiving a statement of their rights. Each delivery needs a notice of the right to a paper copy, and the system must protect confidentiality and result in actual receipt. Retirement plans may instead use the 2020 notice-and-access rule in 29 CFR 2520.104b-31: after an initial paper notice, documents are posted on a website and a notice of internet availability goes to an email address or smartphone number, with free paper copies and a global opt-out. That rule covers pension plans only; its welfare plan paragraph is reserved.

Copies on request. Participants may examine the latest updated SPD and other governing documents at the administrator's principal office and, under 29 CFR 2520.104b-1(b)(3), at any employer establishment where at least 50 participants customarily work, within 10 calendar days of a request. On written request, the administrator must mail copies. ERISA section 502(c)(1) lets a court hold an administrator personally liable for up to $100 a day, adjusted to $110 by 29 CFR 2575.502c-1, when requested information is not mailed within 30 days.

No filing with DOL, but available on request. The Taxpayer Relief Act of 1997 (Pub. L. 105-34) removed the requirement to file plan descriptions and SPDs with the Secretary of Labor. Section 104(a)(6) instead requires the administrator to furnish DOL, on request, the latest SPD and any SMMs. Under 29 CFR 2560.502c-6, a penalty can run from the 30th day after DOL serves the request; DOL first issues a notice of intent, and the administrator has 30 days to file a statement of reasonable cause. The statutory $100 a day and $1,000 per request are inflation-adjusted to $195 and $1,956 by DOL's 2025 rule; DOL's May 27, 2026 notice made no 2026 adjustment because October 2025 CPI-U data were not published, so the 2025 amounts continue. No 2027 adjustment had been published as of November 4, 2026.

SPD versus SBC. The Affordable Care Act added the Summary of Benefits and Coverage, governed by 29 CFR 2590.715-2715 and parallel HHS and Treasury rules. HealthCare.gov describes it as a way to make "apples-to-apples comparisons" between plans. It may not exceed four double-sided pages or use print smaller than 12-point, and it is given with enrollment materials, at renewal, to special enrollees within 90 days of enrollment (the SPD deadline), and within 7 business days of a request. The SBC does not replace the SPD; see ACA (Affordable Care Act) for the wider rules.

Top-hat plans and other exceptions. An unfunded or insured pension plan maintained mainly to provide deferred compensation for a select group of management or highly compensated employees can use the alternative in 29 CFR 2520.104-23: file a one-time electronic statement with DOL within 120 days after the plan becomes subject to Part 1, and provide plan documents to DOL on request. Doing so satisfies the reporting and disclosure rules, so no SPD is distributed.

Where states differ. For private-sector ERISA plans the SPD rule is federal and the same in every state. ERISA section 514 supersedes state laws that relate to these plans, but it does not relieve anyone from state laws that regulate insurance, so insurers issuing group policies still follow state insurance rules for their own certificates and notices. Governmental and non-electing church plans fall outside Title I, and any plan-booklet duties for them come from other law.

Step by step for an employer. (1) Confirm the plan administrator and that every ERISA plan, including insured welfare benefits, has an SPD. (2) Calendar the 90-day deadline from each employee's participation date. (3) Log every plan amendment and its adoption date, and calendar the 210-day SMM deadline, or the 60-day deadline for group health reductions. (4) Track the 5-year and 10-year updated SPD dates. (5) Document delivery method and any electronic consents. (6) Keep a current SPD ready to send to DOL or a participant within 30 days of a request.

Example 1 (illustration): new participant. An employee becomes a participant in a group health plan on February 1, 2027. Counting 90 days, the SPD must be furnished by May 2, 2027.

Example 2 (illustration): SMM timing. A calendar-year 401(k) plan adopts an amendment that is a material modification on September 15, 2026. The SMM is due 210 days after December 31, 2026, which is July 29, 2027, unless an updated SPD describing the change goes out first.

Example 3 (illustration): material reduction. A group health plan adopts an amendment on November 10, 2026 raising its deductible. Because a deductible increase is a reduction in covered services or benefits, the summary is due 60 days after adoption, January 9, 2027, unless the 90-day communication system alternative applies.

Example 4 (illustration): penalty cap. DOL requests an SPD and the administrator does not respond. If DOL assessed the maximum $195 a day, the $1,956 per-request cap would be reached on the 11th day of the failure ($195 x 10 = $1,950; $195 x 11 = $2,145).

Question: Does a small employer's insured health plan need an SPD? Yes, if it is an ERISA plan. 29 CFR 2520.102-3 applies to welfare plans generally, and nothing in 29 CFR 2520.104b-2 exempts small plans.

Question: Can an employer charge for the SPD? Not for the copy it must furnish automatically. 29 CFR 2520.104b-30 allows a charge of up to 25 cents a page only for copies furnished on written request.

Question: Does an SPD go to DOL with the Form 5500? No. The SPD is not filed; DOL's Reporting and Disclosure Guide lists it as a participant disclosure and notes DOL's authority to request plan documents under 29 CFR 2520.104a-8.

This entry summarizes federal rules; it does not decide whether a particular plan, document or delivery method meets them.
