US Treasury Opens GENIUS Act Comment Period as January 2027 Deadline Looms

The US Department of the Treasury has issued a notice of proposed rulemaking tied to the GENIUS Act and invited stakeholder input for 60 days. The law that establishes a federal framework for payment stablecoins is locked in to take effect on January 18, 2027, and every agency involved, including the Treasury, the OCC, the FDIC, and the Federal Reserve Board, reportedly missed the 120-day deadline to finalize implementing rules before that date. For accounting firms, auditors, and CFOs working with stablecoin issuers or digital asset treasury functions, the clock is now running on both the comment window and the compliance timeline.

What the GENIUS Act Actually Requires

Signed into law in July 2025, the Guiding and Establishing National Innovation for US Stablecoins Act creates the first federal licensing regime for payment stablecoins in the United States. The statute set two possible trigger dates for implementation: 120 days after agencies finalize their rules, or 18 months after enactment, whichever comes first. Since 18 months from July 2025 lands on January 18, 2027, that date now functions as a hard deadline regardless of regulatory readiness.

The Licence Requirement

Under the Act, once it goes into effect, an entity generally may not issue a payment stablecoin in the United States without holding a federal or state licence. Treasury's proposed rulemaking begins to define what that licensing process looks like at the federal level. The practical effect is significant: any business that mints, redeems, or operationally controls a stablecoin must either obtain a licence or restructure its activities to fall outside the statute's reach before January 18, 2027.

The Missed 120-Day Deadline and What It Signals

All four agencies involved in GENIUS Act implementation missed the July 2026 deadline to finalize rules. Treasury Secretary Scott Bessent confirmed the department "welcomes input from stakeholders as it works to provide the regulatory certainty businesses need to innovate and grow in America." That language, while conciliatory, acknowledges that certainty is not yet here. The result is a regulatory gap: the law will activate on a fixed date, but the detailed operational requirements may still be in draft form when it does. For compliance teams, that gap is the central planning risk.

The 60-Day Comment Window: Why It Matters for Firms

Public comment periods on financial regulation are sometimes treated as a formality. This one is not. Because the final rules will directly govern licensing criteria, reserve requirements, audit obligations, and reporting standards for stablecoin issuers, submissions from accounting firms and CFOs carry weight. Regulators frequently cite industry comment letters when explaining their final policy choices, and a well-constructed technical letter can narrow ambiguities that would otherwise create compliance cost or legal uncertainty.

What to Comment On

Firms advising stablecoin clients should focus comments on areas where the draft rule leaves operational questions open. Key areas likely to be relevant include the definition of "payment stablecoin" and whether particular treasury or settlement instruments fall within it, the form and frequency of reserve attestations or audits required to maintain a licence, how capital and liquidity requirements will interact with existing banking rules for chartered entities, and the treatment of foreign stablecoin issuers that serve US customers. These are not abstract policy questions; each one has a direct line to audit scope, financial statement presentation, and the advice a firm gives to board-level clients.

Accounting and Audit Implications

The GENIUS Act's licensing requirement will create a new category of regulated entity in the US financial system. For accounting purposes, that has several near-term consequences that firms need to start mapping now.

Reserve Asset Presentation and Classification

A licensed stablecoin issuer will be required to hold qualifying reserve assets against its outstanding stablecoin liabilities. How those assets are classified on the balance sheet, whether as cash equivalents, short-term investments, or restricted funds, depends on the final rule's definition of permissible reserves and the conditions attached to their use. Until the final rule is published, auditors working on year-end 2026 engagements should treat this as a significant accounting estimate or disclosure risk and flag it in planning conversations with clients.

Attestation and Audit Scope

The Act is expected to require some form of periodic attestation or audit of reserve adequacy. The precise standard, whether that means a full financial statement audit, an agreed-upon procedures engagement, or a regulatory examination, will be determined in the final rules. Firms should anticipate expanded scope for any client that becomes a licensed issuer and should begin discussing engagement letter terms and fee structures now rather than after January 2027.

Digital Asset Accounting Software and Workflow Readiness

Tracking reserve composition, reconciling on-chain balances to off-chain custody records, and producing periodic compliance reports will require capable crypto accounting software workflows. Firms that have not yet built or tested these processes against a regulatory-grade standard should treat the January 2027 date as a systems-readiness deadline, not just a legal one. Digital asset accounting software that can reconcile reserve wallets to general ledger entries and produce timestamped audit trails will be essential for any licensed issuer engagement.

The UK-US Angle and Its Implications

In July 2026, the UK-US Financial Regulatory Working Group discussed GENIUS Act implementation as part of broader bilateral coordination. The UK has its own stablecoin regulatory process underway, but it has not yet reached the same stage of statutory certainty. Industry observers have noted that the UK's slower timeline has prompted some in the crypto sector to argue that Britain risks falling behind the US as a stablecoin hub. For accounting firms with cross-border clients, this divergence creates a dual-track compliance challenge: entities operating in both markets face different licensing timelines, different reserve requirements, and potentially different audit standards on each side. Our earlier coverage of ICAEW's stablecoin accounting and assurance analysis covers the UK-side considerations in detail.

What Accounting Firms and CFOs Should Do Now

The combination of a fixed implementation date and incomplete final rules creates a specific type of compliance risk: one where the obligation exists but the precise form of compliance is still being written. That is not a reason to wait. It is a reason to act on what is already clear and to track what remains open.

Immediate Steps

First, identify which clients are or could become "payment stablecoin issuers" under the Act's current definition. The licensing obligation attaches to issuers, so the first question is always whether your client falls within that category. Second, assess whether those clients currently hold the type of reserve assets the Act anticipates, and whether their custody and reconciliation processes can support a regulatory-grade audit. Third, prepare to submit a comment letter, or advise clients to do so, before the 60-day window closes. Finally, review engagement terms for any stablecoin client to ensure they reflect the expanded assurance and attestation work that the final rules are likely to require.

Frequently Asked Questions

When does the GENIUS Act take effect?

The Act takes effect on January 18, 2027. That date is fixed at 18 months after enactment in July 2025 and does not depend on whether agencies finalize their implementing rules beforehand.

Which agencies are involved in writing the implementing rules?

The US Treasury, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, and the Federal Reserve Board are all involved. All four missed the July 2026 deadline to finalize rules before the January implementation date.

How long is the public comment period, and how do firms submit?

The comment period runs for 60 days from the date Treasury's proposed rule is published in the Federal Register. Submissions are made through the standard Federal Register comment process, typically via regulations.gov.

What does "payment stablecoin" mean under the Act?

The Act defines payment stablecoins by reference to their function as a medium of exchange or settlement instrument pegged to a fixed monetary value. The precise boundaries of that definition, including which treasury or settlement tokens fall within it, are among the key questions the proposed rulemaking is expected to address.

What should a firm advising a stablecoin client do before January 2027?

At a minimum: confirm whether the client meets the issuer definition, assess reserve asset composition and custody arrangements, evaluate whether existing audit or attestation engagements cover the likely regulatory requirements, and engage counsel to review licensing options at the federal and state level. Submitting a comment letter is also advisable if the client's operations are affected by unresolved definitional questions in the proposed rule.
