What Is IRS Publication 6088?
IRS Publication 6088 provides sample plan provisions (known as Listings of Required Modifications or LRMs) that help defined contribution plans qualify under Internal Revenue Code (IRC) Section 401(a). These samples ensure plans meet nondiscrimination, coverage, vesting, contribution limits, distribution, and other qualification requirements.
The IRS issues LRMs to speed up the approval process for pre-approved plans (formerly prototype and volume submitter plans). Plan providers use the language to create model documents that receive IRS opinion letters, giving adopting employers reliance that their plans are qualified.
Key features include:
- Sample language tailored to IRC requirements and recent guidance.
- Redlined version showing changes from prior editions.
- Adaptability for standardized and nonstandardized plans.
- Integration of updates from the 2023 Cumulative List of Changes in Plan Qualification Requirements (Notice 2024-3).
The publication references laws like the CARES Act, SECURE Act of 2019, and SECURE 2.0 Act of 2022, making it essential for modern retirement plans.
Defined benefit vs. defined contribution plans – Publication 6088 focuses on the latter, where benefits depend on contributions and investment performance.
The Listing of Required Modifications (LRM): A Quick Overview
The LRM is the heart of Publication 6088. It offers ready-to-use or adaptable language for plan documents in these formats:
- Basic plan document + adoption agreement (most common for pre-approved plans).
- Single plan document.
Provisions are organized into three parts:
| Part | Applies To | Key Features |
|---|---|---|
| Part I | All plans | Core definitions (e.g., compensation, year of service), participation, contributions, vesting, distributions, top-heavy rules, loans, and amendments. |
| Part II | Standardized plans | Stricter uniformity: full compensation definition, allocations for participants with 500+ hours or last-day employment, and broad benefit availability. |
| Part III | Nonstandardized plans | More flexibility, e.g., optional one-year holdout rule, higher eligibility thresholds (up to 1,000 hours). |
This structure helps providers customize while ensuring IRS compliance.
Who Needs IRS Publication 6088?
- Plan providers and mass submitters — Drafting or updating pre-approved plan documents for IRS opinion letters.
- Third-party administrators (TPAs) and consultants — Ensuring client plans meet qualification standards.
- Employers and plan sponsors — Adopting pre-approved plans or verifying amendments.
- Attorneys and ERISA professionals — Advising on plan design, especially for profit-sharing, 401(k), or target benefit plans.
If your organization offers or maintains a defined contribution plan, Publication 6088 is indispensable during restatement cycles (e.g., Cycle 4 for defined contribution plans).

Why Compliance with Publication 6088 Matters?
