DOL Faces 40,000 Comments on New Retirement Plan Rules

The Department of Labor's (DOL) latest proposed changes to ERISA regulations have triggered an unusually high volume of public feedback, with more than 40,000 comments submitted during the official review period. The scale and substance of these responses highlight the stakes for retirement plan fiduciaries, plan sponsors, and investment advisors as the DOL weighs new rules that could reshape how private assets are included in workplace retirement plans.

According to reporting by Broadcast Retirement Network, the majority of comments were so-called "form" submissions-template responses organized by advocacy groups or industry stakeholders. Of the total, roughly 12,000 supported the proposed rule, while about 31,000 opposed it. Yet, regulatory experts note that the DOL is likely to focus on the relatively small subset of substantive comments-those offering detailed analysis or specific recommendations-rather than the raw numbers for or against.

Substantive Feedback

Within the more than 200 substantive comments identified, support and opposition were more evenly split. Many of the most detailed responses came from organizations representing fiduciaries, plan sponsors, and investment consultants. The American Retirement Association, for example, backed the rule but suggested refinements to reduce the risk of new litigation. Aon, a major consulting firm, described the proposal as a positive step toward reducing regulatory uncertainty that has grown over the past decade.

Plan sponsor groups were especially vocal, with the ERISA Industry Committee, American Benefits Council, Chamber of Commerce, and other major organizations expressing strong support. Their main concern: ongoing litigation risk that has made some employers hesitant to offer a broader range of investment options, including private market assets, to their employees. Asset managers and recordkeepers, such as the Investment Company Institute and SPARK, also weighed in, as did alternative asset industry groups and organizations representing diverse employers.

Key Issues and Industry Concerns

Much of the debate centers on whether the proposed rules would make it easier or harder for retirement plans to include private assets-such as private equity or real estate funds-within 401(k) and similar plans. Supporters argue that the changes would provide clearer guidance and a "safe harbor" for fiduciaries, reducing the threat of lawsuits and allowing more diversified investment options for workers. Critics, including some financial planner groups, worry that the rules could be misinterpreted or inadvertently favor certain products, potentially exposing plans to new risks or compliance burdens.

Several commenters flagged technical issues, such as how liquidity and valuation requirements might be applied. Some warned against embedding Securities and Exchange Commission (SEC) rules designed for mutual funds into ERISA guidance, arguing that this could disadvantage collective investment trusts, which are widely used in target-date funds. Others called for updates to existing prohibited transaction exemptions to reflect the broader range of investment vehicles now available in the retirement market.

What Happens Next

The DOL is now reviewing the comments, a process that involves identifying and responding to significant points raised by the public. Under the Administrative Procedure Act, the agency must address substantive feedback in its final rulemaking documents. While not every comment will be read in full, the DOL is experienced at filtering for those that raise legal, economic, or operational issues that require a response.

The regulatory timeline remains uncertain, but the White House's Office of Management and Budget recently indicated that the DOL aims to complete its analysis of public comments by August. If the process moves quickly, a final rule could be published by late 2026 or early 2027, with an effective date likely 60 days after publication. The proposed changes are not expected to impose new mandatory requirements, but rather to clarify existing standards and offer a safe harbor for fiduciaries who choose to follow the new guidance.

Broader Implications

For plan sponsors and fiduciaries, the outcome of this rulemaking could affect both the range of investment options available to workers and the legal risks associated with offering them. The debate reflects broader trends in the retirement industry, where litigation over plan fees, investment selection, and fiduciary process has become increasingly common. The DOL's final approach will likely influence how employers balance innovation in plan design with the need to manage compliance and litigation exposure.

According to the Investment Company Institute, as of year-end 2025, U.S. retirement assets totaled approximately $39 trillion, with defined contribution plans such as 401(k)s accounting for about $11 trillion. The inclusion of private assets in these plans remains limited, but industry advocates argue that expanding access could improve diversification and long-term returns for participants. At the same time, concerns about liquidity, transparency, and valuation persist, especially as more complex investment products enter the retirement space.

ERISA, the Employee Retirement Income Security Act, sets the federal standards for private-sector retirement plans, including fiduciary duties, investment selection, and participant protections. One of the law's core requirements is that fiduciaries act prudently and solely in the interest of plan participants. The DOL's regulatory guidance shapes how these duties are interpreted and enforced. As retirement plan menus evolve to include more diverse assets, the challenge for fiduciaries is to balance innovation with the need for robust due diligence, clear disclosures, and ongoing monitoring of investment risks. The outcome of the current rulemaking could set important precedents for how these responsibilities are managed in the years ahead.
