SEC Plans Rules for Tokenized Stocks: What Accounting Firms and CFOs Must Assess Now

The US Securities and Exchange Commission is preparing rulemaking specifically aimed at tokenized stocks, according to a report published by Decrypt on 13 August 2026. For accounting firms, auditors, and CFOs advising clients who hold, issue, or trade tokenized equities, this is not a distant regulatory curiosity. The direction of travel is now clear enough to warrant immediate action on classification policy, systems readiness, and internal controls, long before any final rule is published.

What the SEC Is Signalling

The SEC's intention to develop specific rules for tokenized stocks marks a meaningful shift in how the agency is approaching the intersection of traditional securities and blockchain-based instruments. Rather than relying solely on the application of existing securities law to these products, the regulator appears to be moving toward a bespoke framework that acknowledges the structural differences between a conventional equity and its on-chain equivalent.

Why a separate framework is significant

Tokenized stocks are, at their core, blockchain-based representations of underlying equity securities. They can take several structural forms: a direct on-chain issuance of the security itself, a wrapper that references an existing share, or a synthetic instrument that tracks a share's price without conveying direct ownership. Each of these structures carries different legal, accounting, and tax consequences, and existing US securities regulation was not written with these distinctions in mind.

The SEC signalling that it plans dedicated rules suggests the agency recognises that applying legacy frameworks wholesale creates ambiguity, both for issuers and for the intermediaries, broker-dealers, custodians, transfer agents, and advisers, who service them. For accounting professionals, that ambiguity has real consequences for how these instruments are classified, measured, and disclosed on financial statements.

Connection to broader SEC crypto rulemaking

This development does not sit in isolation. The SEC has been building a more structured approach to digital asset markets throughout 2026, including work on conditional exemptions from securities registration for certain crypto instruments. The tokenized stock rulemaking appears to be another layer of that effort, extending regulatory attention from native crypto assets to hybrid instruments that blend traditional securities with blockchain delivery mechanisms. Firms tracking the SEC conditional exemption from securities registration for crypto should treat the tokenized stock initiative as a related strand of the same regulatory programme.

Accounting Classification: The Central Challenge

From an accounting standpoint, the classification of a tokenized stock is not self-evident, and the answer depends heavily on the instrument's precise legal and economic structure. This is where firms and CFOs need to concentrate their immediate analytical effort.

Equity, financial instrument, or digital asset?

If a tokenized stock conveys genuine legal ownership of the underlying share, the accounting treatment should mirror that of a conventional equity investment. Under US GAAP, that typically means classification as an equity security measured at fair value through earnings under ASC 321, or, for entities that qualify, at cost less impairment. The fact that the instrument is held on-chain and represented by a token does not, in itself, change the economic substance.

The complications arise when the instrument is structured as a wrapper or a synthetic. A wrapper that holds the underlying share in a custodial arrangement and issues a corresponding token may resemble a beneficial interest in a trust or a structured product rather than a direct equity holding. A synthetic that tracks price without conveying ownership may look more like a derivative under ASC 815 than an equity under ASC 321. These distinctions have downstream effects on measurement, hedge accounting eligibility, and earnings volatility.

FASB ASU 2023-08 and its limits

FASB's ASU 2023-08, which introduced fair value measurement for certain crypto assets, applies to fungible, non-security digital assets. Tokenized stocks, if they are treated as securities, fall outside that standard's scope. That means firms cannot simply apply the new crypto fair value rules and move on. They need to determine whether the tokenized stock is a security first, and if it is, revert to the relevant financial instruments standards. When SEC rulemaking clarifies the legal status of these instruments, it will directly inform which accounting standard applies. Firms that have already mapped their clients' holdings against this question will be ahead of those starting from scratch.

Audit and Internal Controls Implications

For audit teams, tokenized stocks introduce a set of verification challenges that do not arise with conventional equities held through a central securities depository.

Existence and completeness

Confirming that a client actually holds a tokenized stock requires verifying both the on-chain token position and the existence and integrity of the underlying security it represents. That is a two-layer confirmation exercise. Auditors need to be satisfied that the custodian or smart contract holding the underlying asset is solvent and that the token genuinely represents the claimed interest. Standard third-party confirmation procedures may need to be adapted or supplemented with blockchain-native verification.

Custody and segregation of assets

The SEC's existing broker-dealer custody rules were designed for securities held in book-entry form through recognised depositories. Tokenized stocks held in on-chain wallets may not fit neatly within those arrangements, at least until new rules clarify the permissible custody structures. CFOs and compliance officers at firms holding these assets should review whether current custody arrangements will satisfy whatever requirements the SEC ultimately imposes, and document the controls they rely on in the interim.

Valuation evidence

Where a tokenized stock trades on a regulated venue with observable prices, fair value measurement is relatively straightforward. Where it trades on a less liquid or unregulated venue, or where the token's price diverges from the underlying share price due to liquidity or structural differences, auditors will need to assess the appropriateness of the valuation methodology and obtain sufficient evidence to support it. The robustness of your crypto compliance reporting infrastructure matters here: systems that can capture on-chain transaction data and reconcile it to off-chain records are essential.

Tax Reporting and the Broker Question

The tax treatment of tokenized stocks under US federal law is likely to follow the same characterisation analysis as the accounting treatment. If the instrument is a security, gains and losses should be treated as capital gains and losses, potentially subject to the wash sale rules that do not currently apply to native crypto assets. That distinction matters enormously for tax planning and loss harvesting strategies.

1099-DA and broker obligations

The IRS's Form 1099-DA regime, which imposes reporting obligations on digital asset brokers, is already in train. Whether the entities that facilitate tokenized stock transactions will be treated as brokers subject to 1099-DA, or as broker-dealers subject to the existing 1099-B regime, is one of the open questions that SEC and IRS rulemaking will need to address in a coordinated way. Accounting firms advising clients who trade tokenized stocks should flag this ambiguity and ensure that whatever tax reporting their clients receive is appropriate for the instrument's legal classification. The broader landscape of PARITY Act and digital asset tax reform implications is relevant context here, as Congress is simultaneously revisiting the tax treatment of digital assets at a structural level.

Wash sale exposure

If tokenized stocks are confirmed as securities, the wash sale rules under IRC Section 1091 would apply. This would prevent clients from selling a tokenized stock at a loss and reacquiring a substantially identical position within 30 days to realise the tax loss. Given that many clients currently trade digital assets with the assumption that wash sale rules do not apply, any reclassification of tokenized stocks as securities could require a material change in tax strategy. Firms should be having this conversation with affected clients now, not after the rule lands.

What Firms Should Do Before Rulemaking Concludes

Waiting for a final SEC rule before acting is a strategy with real costs. The rulemaking process will include a comment period, and the industry's collective response will shape the final outcome. Accounting firms with genuine technical views on classification, custody, and reporting should consider participating in the comment process. Beyond that, several practical steps are worth taking now.

Immediate priorities for accounting firms and CFOs

First, identify which clients hold, issue, or facilitate tokenized stocks. That inventory exercise is the foundation for everything else. Second, review the legal documentation for each instrument to determine whether it conveys direct equity ownership, a beneficial interest, or a synthetic exposure. Third, assess whether your current crypto accounting software and digital asset accounting software infrastructure can capture the data fields needed to support dual-layer verification, on-chain token data plus underlying security data. If not, that gap needs to be on the technology roadmap before the rule is finalised.

Fourth, engage with legal counsel on the custody question: are current arrangements likely to satisfy the SEC's forthcoming requirements, or will changes be needed? Fifth, brief tax partners on the wash sale exposure so that client communications can be prepared proactively. The regulatory calendar is moving, and firms that treat this as a planning item rather than a reactive one will serve their clients better.

Frequently Asked Questions

What is a tokenized stock?

A tokenized stock is a blockchain-based instrument that represents an interest in an underlying equity security. The precise legal structure varies: some tokenized stocks convey direct ownership of the underlying share, others represent a beneficial interest held by a custodian, and others are synthetic instruments that track the share price without conferring ownership. Each structure has different legal, accounting, and tax implications.

How should a tokenized stock be classified under US GAAP?

Classification depends on the instrument's legal structure. If it conveys direct equity ownership, it is likely an equity security under ASC 321, measured at fair value through earnings. If it resembles a beneficial interest or a structured product, other financial instrument standards may apply. If it is a derivative, ASC 815 applies. FASB ASU 2023-08 on crypto asset fair value does not apply to instruments classified as securities, so the classification question must be resolved before the accounting treatment can be determined.

Will the SEC's tokenized stock rules affect Form 1099-DA reporting?

Potentially, yes. If the SEC classifies tokenized stocks as securities, the question of whether they fall under the 1099-DA digital asset broker regime or the existing 1099-B broker-dealer regime will need to be resolved, likely through coordinated action between the SEC and the IRS. Accounting firms should monitor both agencies' guidance and ensure client reporting reflects the correct framework once the position is clarified.

Do the wash sale rules apply to tokenized stocks?

If tokenized stocks are confirmed as securities under US federal law, the wash sale rules under IRC Section 1091 would apply, preventing clients from claiming tax losses on sales followed by reacquisition of substantially identical positions within a 30-day window. This is a material change from the current treatment of most digital assets, which are not subject to wash sale rules. Firms should assess client exposure now and adjust tax planning strategies accordingly.

How should audit teams approach the existence assertion for tokenized stocks?

Verifying existence requires a two-layer approach: confirming the on-chain token position through blockchain-native procedures, and confirming that the underlying security it represents actually exists and is held by the custodian or smart contract as claimed. Standard third-party confirmation procedures used for conventional securities may need to be adapted to address both layers. Audit methodology should be reviewed and updated before the next engagement cycle for any client holding these instruments.
