- The U.S. Department of Labor proposed new rules allowing alternative assets like private equity in 401(k) plans.
- Stakeholders have a 60-day comment period ending May 29, 2026, to influence the final regulatory framework.
- The proposal introduces a fiduciary safe harbor to protect plan sponsors who perform rigorous due diligence on investments.
(UNITED STATES) — 401(k) plan sponsors, trustees, and workers saving through employer plans now face a key federal deadline: the U.S. Department of Labor’s proposed rule on alternative assets opened for public comment on March 30, 2026, and the 60-day comment period is expected to run through May 29, 2026.
The proposal is not an IRS filing deadline for individual taxpayers. Still, it matters to immigrants, visa holders, and other workers who use 401(k) plans to build U.S. retirement savings. If finalized, the rule would let fiduciaries add broader investment options, including private equity, private credit, real estate, infrastructure, commodities, and certain digitally managed assets, while still meeting ERISA duties.
For tax year 2026 returns filed in 2027, this proposal does not change Form 1040 filing dates or the basic tax treatment of 401(k) contributions. It could, however, change what investments appear inside employer retirement plans in coming years.
Deadline summary
| Event | Date | Who it affects | Extension available |
|---|---|---|---|
| DOL proposed rule issued | March 30, 2026 | Plan sponsors, trustees, asset managers, participants | No |
| Public comment period opens | March 30, 2026 | Employers, workers, industry groups | No |
| Expected close of 60-day comment period | May 29, 2026 | Anyone wishing to comment | Generally no, unless DOL extends it |
| Final rule date | Not yet announced | Defined contribution plans, including 401(k)s | Not applicable |
If your employer, plan committee, or industry group wants to comment on the proposed rule, act before the expected May 29, 2026 deadline.
What the proposal would do
The DOL proposal would allow trustees of defined contribution plans, including 401(k) plans, to include alternative assets if they follow a careful review process. The purpose is to broaden investment access beyond the mutual funds and bond options that dominate many plans today.
The proposal follows the Executive Order issued on August 7, 2025, titled Democratizing Access to Alternative Assets for 401(k) Investors. That order directed the DOL and SEC to reduce regulatory barriers and litigation risk for retirement plans.
The administration said the target audience includes more than 90 million 401(k) participants.
For workers on H-1B, L-1, O-1, TN, and green card status, this matters because they are often eligible for employer retirement plans and usually build long-term U.S. retirement savings. For many F-1 and J-1 workers, access depends on employer plan rules and work authorization, but the proposal could still affect investment menus if they participate.
How the safe harbor would work
The proposal creates a safe harbor for trustees and other fiduciaries. To get that protection, they must review investments “objectively, thoroughly, and analytically.”
That review should cover factors such as:
- Performance
- Fees and expenses
- Liquidity
- Valuation methods
- Benchmarks
- Complexity
If fiduciaries document that process and apply it carefully, the safe harbor is designed to shield them from certain lawsuits over the decision to include these assets.
That protection matters because retirement plan litigation has been rising. The proposal responds in part to disputes like the 2019 Intel employee lawsuit over hedge funds and private equity, which is now under Supreme Court review.
The safe harbor is not automatic. A trustee who skips due diligence, ignores fees, or fails to vet managers may still face ERISA claims.
What kinds of assets are covered
The Executive Order defines alternative assets broadly. The proposed rule points to private market investments, real estate debt, infrastructure, commodities, digital asset vehicles, and longevity-related strategies.
One detail is especially important: the proposal points to indirect exposure for digital assets. That means a plan could use an actively managed vehicle with exposure to digital assets, including cryptocurrencies, rather than allowing direct crypto purchases by participants.
Treasury Secretary Scott Bessent called the proposal an “initial step” focused on protecting retirement assets. SEC Chair Paul Atkins emphasized diversified long-term investing and proper process.
What happens if the deadline is missed
If stakeholders miss the public comment deadline, the main consequence is practical, not tax-related. They may lose the chance to influence:
- The scope of the safe harbor
- How digital assets are treated
- Audit and reporting burdens
- Fiduciary standards for plan committees
For employers and plan sponsors, that could matter later if the final rule raises compliance costs.
The proposal also notes that plans adding these assets may trigger audit changes. In some cases, a plan may need a full-scope audit under 29 CFR 2520.103-5, which can increase administrative costs.
Special timing and relief issues
As of March 31, 2026, no disaster relief or special extension has been announced for this DOL comment period. If the agency extends the deadline, it would typically do so through a formal notice.
The rulemaking timeline already ran late. The Executive Order gave agencies 180 days, which pointed to February 3, 2026. The proposal did not appear until March 30, 2026.
Tax and reporting context for immigrant workers
This is mainly an ERISA and retirement-plan rule, not an IRS filing change. Still, immigrant workers should keep a few tax points in mind:
| Item | Current rule for tax year 2026 | IRS reference |
|---|---|---|
| 401(k) elective deferrals | Reduce current taxable wages for federal income tax purposes, subject to plan and IRS limits | IRS retirement plan guidance at irs.gov/individuals/international-taxpayers and irs.gov/forms-pubs |
| Early distributions | May be taxable and may trigger extra tax unless an exception applies | IRS Publication 575 |
| Residency status | Tax residents generally report worldwide income; nonresidents follow different rules | IRS Publication 519 |
If you are a recent immigrant, dual-status filer, or treaty claimant, your 401(k) contributions and distributions can interact with your residency status. Publication 519, U.S. Tax Guide for Aliens, remains the main IRS reference.
If you changed from F-1 to H-1B or became a green card holder this year, review your residency status before making major retirement moves.
What to do now
If you are a worker, ask your employer whether its 401(k) committee expects to comment on the proposal.
If you are a plan sponsor or fiduciary, prepare now:
- Review current investment policy statements
- Identify any interest in alternative assets
- Document fee, liquidity, and valuation review standards
- Check whether added holdings could change audit requirements
- Watch DOL and IRS updates at irs.gov/forms-pubs and irs.gov/individuals/international-taxpayers
For immigrant families, keep your immediate tax deadlines separate from this rulemaking deadline. This proposal does not replace your normal federal filing dates, FBAR due dates, or treaty disclosure obligations for tax year 2026.
Take action before the expected May 29, 2026 comment deadline if this rule could affect your retirement plan. If you hold plan assets through a visa transition, status change, or dual-status tax year, get plan and tax advice early.
