Ways and Means Advances Digital Asset Tax Certainty Act
The House Ways and Means Committee voted 38-5 on September 16, 2026 to advance the Digital Asset Tax Certainty Act (DATCA), giving US crypto tax reform its clearest legislative endorsement to date. For accounting firms advising clients on digital asset positions, and for CFOs managing treasury exposure to cryptocurrency, the bill introduces two provisions that could reshape compliance workflows almost immediately once enacted: a sourcing rule for staking and mining income and a voluntary-disclosure safe harbor. Neither is law yet, but the bipartisan margin and the political timing make this the most credible crypto tax vehicle currently moving through Congress.
What the Clarity Act Failure Changes
The week before the Ways and Means vote, the Senate failed to advance the Digital Asset Market Clarity Act, commonly called the Clarity Act, on a 49-50 procedural vote on September 15. That bill was the centerpiece of a years-long effort to restructure digital asset market regulation, most notably by shifting jurisdictional authority over the majority of digital assets to the Commodity Futures Trading Commission rather than the Securities and Exchange Commission.
Three distinct forces sank it. Ethics provisions aimed at preventing token offerings by sitting public officials drew resistance. Banks raised concerns about capital flight if the bill loosened regulatory guardrails. And a bloc of senators opposed the underlying policy shift. Senate Democrats signalled continued willingness to negotiate, leaving open the possibility of a return to the bill in a lame-duck session after the November 3 midterm elections, though that outcome is described by Grant Thornton as possible rather than probable.
Why the Two Bills Are Linked
DATCA and the Clarity Act were always companion pieces of a broader digital asset reform agenda, alongside the 2025 GENIUS Act and related stablecoin efforts. The collapse of the Clarity Act makes DATCA the primary legislative vehicle still in motion. Grant Thornton's analysis notes that digital asset tax reform would make sense to bundle with any eventual financial regulatory breakthrough, which means DATCA's fate could remain tied to Clarity Act negotiations even as it moves forward independently.
For firms tracking US legislative risk, the practical implication is this: the Clarity Act's failure does not kill DATCA, but it does mean DATCA alone cannot resolve the foundational question of whether a given token is a commodity or a security. That unresolved question continues to create accounting classification uncertainty, particularly for firms using digital asset accounting software that needs a regulatory anchor to automate asset categorisation.
The Two Core DATCA Provisions
The bill as reported by Ways and Means contains two provisions with direct accounting and tax consequences.
Sourcing Rule for Staking and Mining Rewards
DATCA would clarify that staking and mining rewards attributable to a qualified business unit operating in the US are taxable as US-source income. This closes an interpretive gap that has allowed some taxpayers to argue that the distributed, borderless nature of blockchain validation means rewards lack a clear sourcing rule under existing law.
For accounting firms with clients operating validator nodes or mining facilities, this provision would remove ambiguity at the income-sourcing stage. The practical effect on crypto bookkeeping software workflows is significant: systems will need to tag staking and mining receipts with a US-source flag and apply the appropriate federal income tax treatment at the point of recognition, rather than treating sourcing as a year-end judgment call.
Notably, the bill does not resolve the separate and more contested question of when staking and mining rewards are taxable, that is, whether income arises at the moment rewards are received or only upon disposal. That issue was deliberately left out of the committee markup. Rep. Steven Horsford, the Nevada Democrat who cosponsor the bill alongside Ways and Means Chair Jason Smith, acknowledged on the record that the committee has "more work to do" on that question. The IRS's existing administrative position and the pending litigation in this area remain the operative guidance until Congress acts.
Voluntary Disclosure Safe Harbor
The second provision creates a temporary safe harbor for individuals who come forward voluntarily to disclose past failures to report digital asset gains. Qualifying disclosures would attract reduced penalties rather than the full penalty schedule that would otherwise apply.
This is a meaningful carrot for the large population of retail and institutional participants who entered the digital asset market during 2020-2024 without adequate tax reporting infrastructure. The safe harbor's temporary nature means the window will close. Firms advising individual clients or managing family office crypto positions should treat this as a time-sensitive planning opportunity and begin reviewing exposure now, before the bill advances to a floor vote and the legislative clock shortens further.
What Was Left Out and Why It Matters
The exclusion of any staking and mining income timing rule is the most consequential gap in the current draft. Without congressional clarity, the IRS's position, most recently articulated in Revenue Ruling 2023-14, that staking rewards are taxable as ordinary income upon receipt, remains in force. Taxpayers who have taken a contrary position face ongoing audit risk, and the Jarrett v. United States litigation has not produced a binding circuit-level ruling that advisers can rely on with confidence.
Implications for Audit and Assurance Teams
Accounting firms providing attest or advisory services to digital asset clients need to document their treatment of staking income consistently with current IRS guidance, noting in client files that the timing question remains legislatively unresolved. Any departure from the revenue ruling position should be supported by a documented legal analysis, not simply by the existence of DATCA, which is not yet law and does not address timing in any case.
Firms should also revisit their digital asset accounting software configurations to confirm that staking receipt events are captured at the correct recognition point and that the software generates a clear audit trail linking each receipt to its fair market value at the time of receipt. That audit trail will matter whether the timing rule ultimately changes or stays the same.
Legislative Path and Political Calendar
The bipartisan 38-5 committee vote gives DATCA genuine momentum. Chair Smith has made crypto tax legislation a stated priority. However, the full House is not scheduled to reconvene until November 9, after the midterm elections on November 3. That compressed post-election window, commonly called a lame-duck session, is also when the Senate might return to the Clarity Act if negotiations resume.
Senate Finance and the TAS Act Complication
On the Senate side, Finance Committee Chair Mike Crapo has concentrated his bandwidth on the bipartisan Taxpayer Assistance and Service Act (TAS Act), a tax administration reform bill. That bill competes for floor time and political attention with both DATCA and any revived Clarity Act negotiations. Grant Thornton's assessment is that DATCA becoming law before year-end is plausible but not certain, and that its prospects improve materially if it can be attached to a broader legislative package.
The committee also advanced the EFIN Verification Act, introduced by Rep. Ron Estes, which would require the Treasury Department to validate electronic filing identification numbers. That bill runs on the same uncertain timeline as DATCA, with no House floor date yet confirmed.
IRS Leadership and Outstanding OBBBA Guidance
Separately, the Senate Finance Committee held a confirmation hearing on September 15 for James Gadwood, the Trump administration's nominee for IRS general counsel, currently vice chair of the tax practice at Miller and Chevalier. A Tax Court judge nominee, Andrew De Mello, who has been serving as acting IRS general counsel, was also considered. Sen. Ron Wyden, the top Democrat on Finance, was publicly critical of both nominees, signalling a likely party-line confirmation vote. No date has been set for Gadwood's confirmation vote.
Turnover among Treasury political appointees has contributed to delays in several outstanding pieces of guidance related to the One Big Beautiful Bill Act (OBBBA). Firms that have been waiting on OBBBA-related regulatory clarity, including foreign tax credit and FDDEI calculation rules, should not assume those delays will resolve quickly regardless of the confirmation timeline.
Accounting and Compliance Implications for Firms
The Ways and Means vote does not change the law today, but it does change the planning horizon. Here is how accounting practices and CFOs should respond right now.
Immediate Actions for Advisory Practices
First, identify every client with unreported or under-reported digital asset gains, particularly from staking, mining, or DeFi activity in the 2020-2024 period. The proposed safe harbor is designed for exactly this population, and the window will narrow as the bill advances. Voluntary disclosure conversations should begin now, not after the bill passes, because pre-disclosure planning gives clients the most flexibility.
Second, review whether current crypto accounting software configurations will capture the US-sourcing flag for staking and mining rewards automatically once DATCA is enacted. If that flagging requires manual intervention, build the operational change into your implementation roadmap now so the firm is not scrambling at enactment.
Third, check that your digital asset accounting software generates a transaction-level audit trail for staking receipts, with fair market value at receipt date recorded at the event level. This is required under current IRS guidance regardless of DATCA's fate, and it will be essential for any future audit defence or amended return filing under the safe harbor.
For CFOs with Treasury Digital Asset Exposure
If your entity holds digital assets, including tokens earned through staking or yield-bearing DeFi positions, now is the time to run a liability quantification. Estimate the gap between reported income and what would have been reportable under a strict IRS Revenue Ruling 2023-14 interpretation. That number will determine whether the safe harbor is financially attractive and will inform any decision to amend prior-year returns.
The Clarity Act's Senate defeat also means that the commodity-versus-security classification question remains open, which has balance sheet implications for firms applying ASC 350-60 or evaluating whether certain tokens should be measured at fair value. The absence of a legislative classification framework means the accounting judgement continues to rest on facts-and-circumstances analysis, which should be reviewed at least quarterly.
Frequently Asked Questions
Does the DATCA committee vote mean the bill is now law?
No. A favorable committee report is a necessary step but the bill still needs a full House floor vote, Senate passage, and presidential signature. The House is not scheduled to reconvene until November 9, after the midterm elections.
What does DATCA say about when staking rewards are taxable?
It does not address timing at all. The bill clarifies that US-sourced staking and mining rewards from a qualified business unit are taxable in the US, but the question of whether income arises at receipt or only at disposal was deliberately left out of this draft. Current IRS guidance under Revenue Ruling 2023-14 treats rewards as ordinary income upon receipt, and that position remains operative.
Who qualifies for the voluntary disclosure safe harbor?
The bill describes the safe harbor as available to individuals who voluntarily disclose past failures to report digital asset gains. The specific qualifying criteria, the penalty reduction schedule, and the time window have not been finalized in the draft advanced by committee. Firms should monitor the bill text as it progresses and not assume any particular fact pattern qualifies without reviewing the enacted language.
How does this affect how we configure digital asset accounting software?
Two areas need attention. First, ensure your system tags staking and mining receipts as US-source income, which DATCA would make a statutory requirement for qualifying business units. Second, confirm that fair market value at the date of receipt is recorded at the transaction level for every staking event, consistent with existing IRS guidance regardless of whether DATCA passes.
Could DATCA still be bundled with the Clarity Act?
Grant Thornton's analysis notes that digital asset tax reform would logically accompany any financial regulatory breakthrough on the Clarity Act. Senate Democrats have signalled continued willingness to negotiate on the Clarity Act, so a combined package in a lame-duck session is possible, though the same analysis characterises a Clarity Act revival as more possible than probable.
