401(k) Crypto Proposal: Altcoins, Hurdles and Your Books

A proposed US Labor Department rule that could let 401(k) plans offer crypto beyond Bitcoin and Ether reached the White House for final review on Thursday. For finance teams, the headline is not which tokens get in. It is that fiduciaries will have to document valuation, liquidity and pricing for any digital asset they pick, and that is a records and reconciliation problem long before it is a market problem. Firms evaluating crypto accounting software for plan-related work should read this as an early signal about the evidence standard coming their way.

What the Labor Department proposal actually says

According to the Office of Information and Regulatory Affairs, the rule is now at the White House stage. The Labor Department first put the proposal forward in March. Its stated aim is to make it easier for retirement plans to offer alternative investments such as crypto, while giving employers and plan managers more legal protection when they do.

Two details matter most for anyone planning ahead. The proposal does not list which digital assets could be included. It also sets no minimum market capitalization. Instead, it steers plan managers toward six factors when choosing investments: performance, fees, liquidity, valuation, benchmarks and complexity.

What the proposal leaves open

Because there is no approved-token list and no market cap floor, the rule does not exclude altcoins and smaller cryptocurrencies. It also does not guarantee that any of them will be offered. The decision stays with the people running each plan, who would need to show their choices are sensible under the same lens they apply to any other retirement option.

What the rule does not cover

The proposal does not limit crypto exposure to exchange-traded funds or managed funds. In other words, direct holdings are not ruled out on paper. Experts quoted in the source expect the practical path to look different, which is where the accounting and operational questions begin.

Why altcoins face a steeper climb than Bitcoin and Ether

Teresa Goody Guillén, managing partner at Bellementis PLLC, said Bitcoin and Ether are likely to be offered first because of their established markets and investment products. At the time of the source report, Bitcoin and Ether were the two largest cryptocurrencies by market capitalization, at roughly $1.5 trillion and $273 billion respectively, per CoinGecko data as of 20:01 UTC on Nov. 6.

Size is not the test, though. Guillén argued that market cap matters but should not be decisive: big does not mean suitable, and small does not mean disqualified. Her framing is that the real question is whether an investment meets the same standards of prudence, liquidity, valuation and investor protection as any other retirement option, and that digital assets should neither get special treatment nor be excluded because they use different technology.

The practical test from the market side

Bernardo Brites, co-founder and CEO of Trace Finance, put the same idea in operational terms. Run any token through the six-factor list, he said, and Bitcoin passes clearly, Ether passes, and everything else fails on track record or benchmark before a fiduciary ever reaches market cap. For him, market cap matters only indirectly. The working question is whether a plan committee can document a daily, reliable price from a regulated wrapper. If it can't, the asset isn't going in.

Smaller tokens also carry limited history and liquidity, which the experts cite as core obstacles. None of this is a prohibition. It is a documentation burden that most altcoins would struggle to meet today.

Timeline and legal risk: slower than the headline suggests

Brites stressed that the rule changes the legal risk, not the plumbing, and that the plumbing is slower. He pointed to the process ahead: White House review can take up to ninety days, followed by publication, then an effective date typically sixty days later.

The adoption path experts expect

Both experts expect a gradual rollout. Guillén said ETFs and managed funds will likely come first because they fit existing custody and recordkeeping systems. Direct holdings raise extra concerns about storage, cybersecurity and pricing, although she added that those risks should not automatically rule them out. Brites expects existing brokerage options first, then standalone ETFs and funds that include small amounts of crypto. His expectation is that some crypto options appear in 2027, with ETFs at larger employers later that year, and wider availability in retirement funds by 2028. Those are one expert's projections, not regulatory dates.

Why legal uncertainty could slow things further

The proposal would give plan managers some protection from lawsuits, but it would not stop them from being sued over investment decisions. Brites also warned that a future administration could reverse the rule. He noted that the 2022 guidance was reversed in 2025, so a fiduciary signing a ten-year plan design has to weigh the possibility that this rule is undone as well. With courts giving agencies less deference, he added, how much weight the safe harbor carries in litigation is itself unsettled.

For finance leaders, that matters because a rule that might not last is a reason for employers to move cautiously, and for service providers to build optionality rather than a single fixed process.

Accounting and tax implications for firms and CFOs

The source is a regulatory-process story, not a tax ruling, so it does not set accounting or tax treatment. What it does is shape the evidence plan sponsors, recordkeepers and their advisers will need. Reading the six factors as a records checklist is a sensible way to prepare.

Valuation and pricing evidence

Valuation and benchmarks are two of the six factors, and Brites's test is a daily, reliable price from a regulated wrapper. That puts a premium on traceable price sources, consistent valuation timestamps and the ability to show how a number was derived. A firm advising a plan committee, or auditing the vehicle a plan invests in, will want a repeatable method for sourcing and retaining pricing evidence rather than ad hoc screenshots.

Where a plan holds crypto through a fund or ETF, the plan's own books would likely see a pooled investment, while the underlying digital asset records sit with the fund. Where direct holdings eventually appear, the plan side inherits the heavier burden: wallet-level records, custody confirmations and a defensible valuation process. This is where purpose-built digital asset accounting software and disciplined crypto bookkeeping software workflows earn their keep, because they tie transactions, balances and prices into one auditable trail.

Liquidity and complexity as audit topics

Liquidity and complexity are named factors, so expect committee minutes and fiduciary files to address them explicitly. Accountants supporting those files should be ready to evidence how liquidity was assessed and what operational complexity the asset adds, including custody, cybersecurity and recordkeeping fit. Guillén's point that ETFs fit existing custody and recordkeeping systems is, in effect, a statement about reduced complexity.

Tax and reporting angles to monitor

Retirement accounts have their own tax framework, and the source does not describe any change to it. The relevant takeaway is narrower: employers, advisers and participants will ask what crypto exposure inside a plan means for reporting, and answers should come from the final rule text and Treasury and IRS guidance, not from commentary. Until the rule is published, avoid building client advice on assumptions about token eligibility. Track the final text, then map it against your reporting calendar.

What to do now: a practical checklist

Nothing here is final, so the right posture is preparation rather than action. These steps cost little and apply whichever way the rule lands.

For accounting firms and auditors

• Map the six factors (performance, fees, liquidity, valuation, benchmarks, complexity) to the evidence you would request from a plan client.
• Confirm you can source and retain daily pricing with a clear methodology, since a documented daily price is the practical gate Brites describes.
• Decide how you would treat crypto exposure held through a fund versus held directly, and what working papers each would need.
• Watch for the published rule and effective date rather than relying on the expected 2027 and 2028 milestones.

For CFOs and plan sponsors

• Brief the plan committee that the proposal broadens what is permissible, not what is advisable, and that lawsuit exposure does not disappear.
• Build reversibility into plan design thinking, given the 2022 guidance reversal in 2025 that Brites cites.
• Check that your recordkeeping and custody arrangements could support crypto exposure, starting with the ETF and managed fund route experts expect first.
• Review your wider tokenization and digital asset readiness; our note on what finance teams should do as traditional assets are tokenized covers overlapping controls.

Choosing tooling without overbuying

If you are comparing crypto accounting software now, anchor the evaluation on the evidence the six factors imply: price sourcing, valuation history, transaction-level audit trails and reconciliation to custody records. Features that matter only if direct holdings arrive can wait. Features that support documented pricing and clean reconciliation pay off in either scenario.

What is still unknown

Several points remain open, and a careful draft of client advice should say so. The source does not state the final text of the rule. It does not say whether the White House review will change the proposal. It does not set an effective date, and it does not identify any token beyond Bitcoin and Ether as likely to qualify. The 2027 and 2028 timelines are one executive's expectation. Legal protection for plan managers is partial, and the durability of the rule beyond this administration is uncertain.

That uncertainty is itself the planning input. Firms that can evidence valuation, liquidity and custody for digital assets will be positioned for whichever version of the rule is published, and for the fiduciary scrutiny that will follow it.

FAQ

Does the proposed 401(k) rule allow altcoins?

It does not exclude them. The proposal names no specific digital assets and sets no minimum market cap, but it does not guarantee any altcoin will be offered. Plan managers would have to justify choices using six factors, and experts quoted say smaller tokens may struggle on track record, liquidity and benchmarks.

What are the six factors plan managers should consider?

Performance, fees, liquidity, valuation, benchmarks and complexity. For finance teams, each one translates into documentation: pricing evidence, cost records, liquidity assessments and a record of how complexity was weighed.

When could crypto appear in 401(k) plans?

No official date is set. The rule is at White House review, which one expert says can take up to ninety days, followed by publication and typically a sixty-day wait for the effective date. The same expert expects some options in 2027 and broader availability by 2028, but that is a projection.

Will ETFs come before direct crypto holdings?

Experts expect so. ETFs and managed funds fit existing custody and recordkeeping systems, while direct holdings raise concerns about storage, cybersecurity and pricing. Those concerns are not described as automatic disqualifiers.

Why might the rule not last?

One expert noted that earlier 2022 guidance was reversed in 2025, so a future administration could reverse this rule too. Courts also give agencies less deference, so the weight of the legal safe harbor in litigation is unsettled.
