Summary Plan Description (SPD)

A summary plan description is the plain-language booklet an employer must give you describing how your retirement or health plan works. ERISA requires it within 90 days of becoming a participant, and it is the document to reach for before asking anyone at work how the plan works.

Quick Summary

  • You are entitled to one within 90 days of becoming a participant, without asking.
  • The law requires it to be "written in a manner calculated to be understood by the average plan participant," which is an enforceable standard rather than a courtesy.
  • Plan changes are reported in a summary of material modifications, generally due within 210 days after the end of the plan year in which the change was adopted.
  • On written request you can also get the plan document itself, and a court can penalize the plan administrator per day for not producing it within 30 days.
  • Where the summary and the plan document conflict, the plan document controls the benefit. That is not the end of the analysis, because a misleading summary can still support a separate equitable claim.

Definition

A summary plan description, universally called an SPD, is the document ERISA requires a plan to furnish to participants and beneficiaries describing the plan's terms and their rights under it. ERISA section 102(a) sets two standards for it: it "shall be written in a manner calculated to be understood by the average plan participant," and it "shall be sufficiently accurate and comprehensive to reasonably apprise such participants and beneficiaries of their rights and obligations under the plan." Those are legal requirements, not aspirations, and the second one carries an accuracy obligation the first one is often mistaken for softening.

The SPD is a summary of something. The underlying plan document, along with any trust agreement, insurance contract or collective bargaining agreement, is the actual legal instrument. Understanding that relationship is the single most useful thing to know about an SPD, and the most commonly overstated in both directions.

Advanced Explanation

What it must tell you. ERISA section 102(b) lists required content, and the list is more specific than most people expect. Among other items the SPD must state the name and type of administration of the plan; the name and address of the administrator, and of the agent for service of legal process if that is someone else; any trustees; the plan's "requirements respecting eligibility for participation and benefits"; a description of the provisions providing for nonforfeitable pension benefits, meaning vesting; "circumstances which may result in disqualification, ineligibility, or denial or loss of benefits"; the source of the plan's financing; the plan year; "the procedures to be followed in presenting claims for benefits"; and "the remedies available under the plan for the redress of claims which are denied in whole or in part." If you want the vesting schedule, the eligibility rule, or the appeal procedure, the SPD is where Congress required them to be.

The delivery schedule, all of it in section 104(b)(1). A new participant gets the SPD within 90 days of becoming one, or within 120 days after the plan first becomes subject to the statute, whichever is later. Every fifth year the administrator must furnish an updated SPD "which integrates all plan amendments made within such five-year period," with an exception if no amendments were made. Regardless of amendments, an SPD must go out every tenth year. In between, changes are reported through a summary of material modifications, generally due no later than 210 days after the end of the plan year in which the change was adopted; a material reduction in covered services or benefits under a group health plan must go out within 60 days instead.

Getting the real document. Section 104(b)(2) requires the administrator to make the latest SPD, the latest annual report, and the "trust agreement, contract, or other instruments under which the plan was established or is operated" available for examination at its principal office. Section 104(b)(4) goes further: on written request the administrator must furnish copies of those items, and may charge a reasonable amount for the copying. That is the provision that entitles you to the plan document, not merely its summary. The enforcement sits in section 502(c)(1): an administrator who fails or refuses to comply with a request for information it is required to furnish, by mailing it within 30 days, "may in the court's discretion be personally liable to such participant or beneficiary" for a specified amount per day. The penalty is discretionary, it runs per day, and it runs against the administrator personally.

The conflict rule, stated properly. In CIGNA Corp. v. Amara (2011) the Supreme Court held that SPD statements "do not themselves constitute the terms of the plan" for purposes of ERISA's benefit-recovery provision, section 502(a)(1)(B). That much is widely quoted, and it is where most summaries stop. In the same opinion the Court went on to find that "a different equity-related ERISA provision," section 502(a)(3), "authorizes forms of relief similar to those that the court entered" as "appropriate equitable relief," and pointed the lower court on remand to reformation, estoppel and surcharge as the equitable principles it might apply. Stating only the first half tells a participant who relied on a misleading summary that they have no remedy, and that is not what the case decided. The accurate summary is narrower and more useful: the summary does not rewrite the plan's terms, but a materially misleading summary can still be actionable on a different theory.

How to Remember

The plan document is the law of the plan; the summary plan description is the translation you are entitled to receive. Read the summary first, then demand the document if the numbers matter.

Used in a Sentence

“The summary plan description was where Marcus finally found the plan's vesting schedule, after two HR emails had given him different answers.”

How It Works

Two deadlines drive almost everything, and both are arithmetic you can check against a calendar.

A hypothetical example. Priya joins her employer's 401(k) on April 15, 2026. Because ERISA section 104(b)(1)(A) gives the administrator 90 days from the day she became a participant, her SPD is due by July 14, 2026. That same year the employer amends the plan in March to tighten its hardship provisions. Because a summary of material modifications is due no later than 210 days after the end of the plan year in which the amendment was adopted, and the plan runs on the calendar year, the deadline is 210 days after December 31, 2026, which falls on July 29, 2027. Notice how long that is: an amendment adopted in March 2026 may legitimately not be summarized to participants until well over a year later. Anyone relying on an SPD printed before a mid-year amendment should ask whether one has been adopted since.

If Priya wants the plan document rather than the summary, she writes to the plan administrator and asks for it. The administrator may charge a reasonable copying fee. If 30 days pass with nothing, section 502(c)(1) exposes the administrator personally to a per-day penalty at a court's discretion, which in practice is what makes the written request effective.

Pros and Cons

What the SPD is good for

  • It is the one plan document you receive automatically, without asking.
  • It is required to be readable, and to be accurate and comprehensive enough to convey your actual rights and obligations.
  • Its required contents include the practical answers people look for: vesting, eligibility, claims procedures, and how benefits can be lost.
  • It names the plan administrator, which tells you who owes you documents and decisions.
  • It is the natural first step before a written request for the full plan document.

Its limits

  • It is a summary, and where it conflicts with the plan document on the terms of a benefit, the plan document generally governs.
  • It can lag reality by a long way. An amendment adopted early in a plan year may not be summarized for over a year.
  • Nothing forces a plan to volunteer the underlying plan document; you have to request it in writing.
  • Enforcement of the disclosure rules is discretionary with a court, so there is no automatic remedy for a late or missing SPD.

People Also Asked

Answers to the most frequently asked questions.

When am I entitled to a summary plan description?
ERISA section 104(b)(1) requires the plan administrator to furnish it within 90 days after you become a participant, or within 120 days after the plan first becomes subject to the statute if that is later. You should receive it without asking. The administrator must also furnish an updated SPD every fifth year integrating any amendments made in that period, and an SPD every tenth year regardless of whether anything was amended.
Does the summary plan description or the plan document control?
For determining the terms of a benefit, the plan document generally controls. The Supreme Court held in CIGNA Corp. v. Amara that SPD statements do not themselves constitute the terms of the plan for purposes of ERISA's benefit-recovery provision. But the same decision found that a separate provision authorizes similar relief as appropriate equitable relief, so a participant misled by an inaccurate summary is not automatically without recourse. The accurate takeaway is that the summary does not rewrite the plan, not that the summary does not matter.
How do I get my actual plan document, not just the summary?
Ask the plan administrator in writing. ERISA section 104(b)(4) requires the administrator, on written request, to furnish a copy of the latest summary plan description, the latest annual report, and the other instruments under which the plan is established or operated, which includes the plan document. A reasonable copying charge is permitted. If the administrator does not produce it within 30 days, section 502(c)(1) allows a court, in its discretion, to hold the administrator personally liable for a per-day amount.
My plan changed. Should the SPD have been updated?
Not necessarily right away. A plan amendment is reported through a summary of material modifications, which is generally due within 210 days after the end of the plan year in which the change was adopted, so a change made early in a year may legitimately not reach you for more than a year. A material reduction in covered services or benefits under a group health plan has a much shorter fuse: 60 days. A fully updated SPD integrating all amendments is required every fifth year.
Who has to give me the SPD?
The plan administrator, which ERISA section 3(16) defines as whoever the plan document designates and, if it designates nobody, the plan sponsor. For a single-employer plan that means your employer. The SPD is itself required to state the administrator's name and address, so if you already have one, the answer is inside it.
