On July 20, 2024, in a 7-2 decision, the Supreme Court held that the Code Sec. 965 mandatory repatriation tax was constitutional under the Sixteenth Amendment to the Constitution. The majority opinion crafted a very narrow ruling preserving the status quo, but avoiding the principal issue presented to the court.
The Moores had invested in a controlled foreign corporation. They never received distributions from the CFC or paid any tax with respect to the CFC. Under the Subchapter F rules prior to the Tax Cuts and Jobs Act of 2017, shareholders were not taxed on the operating income of a CFC until distribution; however, 10%-or-more shareholders were currently taxed on movable income of the CFC, such as dividends, interest, rents and royalties.
The TCJA created a one-time Mandatory Repatriation Tax under Code Sec. 965 on a 10%-or-more shareholder’s share of the CFC’s post-1986 accumulated earnings, which consisted of the untaxed, undistributed operating income of the CFC.
Financed by groups seeking a ruling that taxation of unrealized sums was unconstitutional under the Sixteenth Amendment without apportionment among the states, since it was a tax on property and not a tax on “income,” the Moores challenged the constitutionality of Code Sec. 965 in court. They also argued that the MRT constituted a retroactive tax in violation of the Due Process Clause of the Fifth Amendment.

The federal district court held that the MRT was taxation of income within the terms of the Sixteenth Amendment. The Court of Appeals for the Ninth Circuit agreed, citing similar taxes that had been held constitutional over the years. The Ninth Circuit also held that the retroactivity of the tax did not violate the Due Process Clause because it served a legitimate purpose in accelerating the repatriation.
The Supreme Court granted certiorari in June of 2023 on the Sixteenth Amendment issue. The issue as framed by Moore was, “Whether the Sixteenth Amendment authorizes Congress to tax unrealized sums without apportionment among the states.” The government framed the issue as, “Whether the Mandatory Repatriation Tax is a tax … on incomes, from whatever source derived.”
Supreme Court decision
The Supreme Court held that the MRT was a tax on income and not a tax on property. The court framed the issue as whether Congress can attribute an entity’s realized and undistributed income to the entity’s shareholders or partners and then tax the shareholders or partners on their portion of the income.
The majority opinion looked to a long line of precedents that Congress can choose to tax either a business entity or its partners or shareholders, such as the taxation of partnerships and S corporations, and the taxation of Subpart F income. The majority opinion limited its decision to situations involving the taxation of shareholders of an entity on the undistributed income realized by the entity that has been attributed to the shareholders when the entity itself has not been taxed on the income.
By limiting its decision to this narrow issue, the court avoided addressing whether the Sixteenth Amendment includes a realization requirement.
Scope of the Moore decision
The court’s decision supports many longstanding taxes in the Internal Revenue Code, including the taxation of partnerships, S corporations, Subpart F income, global intangible low-taxed income (GILTI), real estate mortgage investment conduits (REMICs), passive foreign investment companies income, original initial discount rules for below-market and short-term loans, and mark-to-market rules for securities dealers, regulated futures contracts, imputed rental income, insurance companies, and the Code Sec. 877A exit tax.
The majority opinion does not address issues such as the constitutionality of proposed wealth taxes and the taxation of the appreciated but unrealized value of the assets of individual taxpayers. The opinion also does not address whether a U.S. entity’s realized income that is already subject to U.S. corporate income tax could be attributed to shareholders.
Concurring and dissenting opinions
The majority Supreme Court opinion was authored by Justice Kavanaugh and joined by Chief Justice Roberts, and Justices Sotomayor, Kagan and Jackson. A concurring opinion by Justice Jackson argued that the realization requirement was not constitutionally required under the Sixteenth Amendment. A concurring opinion authored by Justice Barrett and joined by Justice Alito argued that realization is constitutionally required under the Sixteenth Amendment; however, realization by an entity is sufficient to meet the requirement.
A dissenting opinion authored by Justice Thomas and joined by Justice Gorsuch also argued that the Sixteenth Amendment requires the realization of income. It criticized the majority for focusing on attribution and distinguished the MRT from other forms of pass-through taxation in that the other forms of Subpart F taxation related to the earnings of a U.S. shareholder on the earnings of a foreign corporation during the same year as the shareholder’s control.
Combining the concurring opinion of Justices Barrett and Alito and the dissenting opinion of Justices Thomas and Gorsuch, there were a total of four justices arguing that the Sixteenth Amendment includes a realization requirement. Only Justice Jackson’s concurring opinion argues directly that the Sixteenth Amendment does not include a realization requirement.
Wealth tax
A wealth tax has been proposed in the U.S. by some members of Congress and has been implemented in some European countries. Part of the impetus for financing the Moore case was to try to forestall a wealth tax in the U.S. by getting a ruling that a wealth tax would be a violation of the Sixteenth Amendment as a tax on unrealized income. The Supreme Court did not go that far in Moore; however, it appears that at least four of the current justices are prepared to do so.
President Biden has proposed an end to stepped-up basis at death for gains over $5 million per person and $10 million per married couple, with protections for gifts to charity and family for farms and businesses where the heirs will continue to run the business. Biden has also proposed a 25% income tax on those with wealth of more than $100 million.
Senator Elizabeth Warren has proposed a true wealth tax of a 2% annual surtax on the net worth of households and trusts between $50 million and $1 billion and a 6% annual surtax on the net worth of households and trusts above $1 billion.
Having failed to get the current Supreme Court to rule on the realization requirement in Moore, it may be difficult to find an appropriate case to bring the issue again to the Supreme Court until something similar to a wealth tax is enacted.
Should the realization issue come before the current Supreme Court again in the context of a wealth tax, it may be that Chief Justice Roberts and/or Justice Kavanaugh would join the four justices already indicating support for a realization requirement in the Sixteenth Amendment.
Impact
The Supreme Court’s decision preserves the status quo in protecting various provisions of the Internal Revenue Code, including the MRT specifically at issue in the case. It avoided, however, and left for another day, the issue presented by the Moores — whether the Sixteenth Amendment includes a realization requirement.
Corporate accounting departments face an expanded regulatory mandate as mandatory sustainability and Environmental, Social, and Governance (ESG) reporting frameworks take full effect internationally. Governed by the European Union’s Corporate Sustainability Reporting Directive (CSRD) and the International Sustainability Standards Board (ISSB) IFRS S1 and S2 standards, enterprise financial controllers are now legally required to track, verify, and report non-financial data with the same internal controls and auditability as traditional financial statements.
The expansion shifts ESG compliance
This regulatory expansion shifts ESG compliance from marketing departments to corporate accounting offices. Financial managers are now responsible for gathering, consolidating, and verifying carbon emissions metrics, supply chain labor conditions, water usage, and climate risk exposures across multi-tiered corporate structures. These non-financial metrics must be integrated into standardized general ledgers to withstand rigorous third-party audit assurance processes.
To comply with these rigorous reporting mandates, accounting software providers have added dedicated ESG modules designed to aggregate data from IoT sensors, utility platforms, and vendor management systems. Controllers are implementing internal control frameworks—modeled after traditional COSO frameworks—to ensure the completeness, accuracy, and consistency of sustainability disclosures, protecting organizations against greenwashing penalties and litigation risks.
The transition requires significant cross-functional collaboration between accounting teams, legal counsel, and operational directors. Accounting professionals are expanding their technical expertise beyond financial ledgers to master carbon accounting methodologies, lifecycle assessment standards, and non-financial data governance protocols, fundamentally expanding the role of the modern corporate accountant.
Why This Information Matters
Mandatory ESG disclosures require companies to treat environmental and social metrics as audited financial records. Executives, accountants, and board members must institute formal tracking and assurance processes to satisfy legal mandates, maintain investor confidence, and mitigate regulatory non-compliance risks.
A proposal from the U.S. Securities and Exchange Commission to potentially shift some public companies away from quarterly financial reporting toward a semiannual model is drawing significant pushback from investors, even as it continues moving through the regulatory process. The debate has direct implications for corporate finance teams, auditors, and the broader transparency of U.S. capital markets.
What the SEC Proposed
According to a summary published by accounting advisory firm Cohen & Co., the SEC issued a proposed rule on May 19, 2026, aimed at simplifying financial reporting requirements for many U.S. public companies. The proposal would potentially reduce the frequency of certain mandatory disclosures from quarterly to semiannual, a structural change that has not been made to core U.S. reporting requirements in decades.
The proposal follows an extended debate within U.S. policy circles, with proponents arguing that reduced reporting frequency could lower compliance costs and free up management time for longer-term strategic planning rather than quarter-to-quarter results management.
Why Investors Are Pushing Back
Comment letters submitted in response to the proposal have been extensive, and according to Cohen & Co.’s review of the public record, investors “appear to be largely opposed” to the shift, viewing frequent interim reporting as a core benefit of U.S. capital markets relative to other jurisdictions.
Accounting and law firms have taken a more measured position, generally urging any changes to remain aligned with the Financial Accounting Standards Board (FASB), whose existing disclosure requirements and guidance are built around a quarterly reporting cadence. A shift to semiannual reporting without corresponding changes to FASB guidance could create friction between SEC filing requirements and GAAP-based disclosure expectations.
Lessons From the U.K. Experience
The debate is not without precedent. The United Kingdom moved away from mandatory quarterly reporting for listed companies in 2014, returning to a semiannual disclosure requirement. According to Cohen & Co.’s analysis, that experience offers a cautionary data point: there was no measurable increase in capital expenditure or R&D investment following the change, while analyst coverage of affected companies declined as reliable interim information became less available — a particular risk for smaller and newly public companies that rely on analyst coverage to maintain investor visibility.
Practical Implications for Finance Teams
Beyond the debate over disclosure philosophy, the proposal carries practical complications. Many companies have debt covenants and credit agreements structured around quarterly financial delivery; a shift to semiannual reporting could require renegotiating those terms. Reduced reporting frequency would also extend the “window of market silence” between disclosures, a factor that governance and investor-relations teams would need to manage carefully to avoid information asymmetry.
Separately, and unrelated to the reporting-frequency debate, the SEC and FASB have continued finalizing more routine updates this year. New Accounting Standards Updates are taking effect for December 31, 2026, fiscal year-ends covering income tax disclosures, credit loss measurement, induced debt conversions, and stock compensation, according to Eide Bailly’s review of 2026 ASU activity. Additional guidance on paid-in-kind dividends and environmental credits is also on the near-term horizon.
What to Watch Next
The semiannual reporting proposal remains in the comment and review phase, and no final rule has been adopted as of this writing. Finance leaders should monitor the SEC’s regulatory agenda for further movement, while treating the current quarterly reporting requirement as the operative standard until any final rule is issued and an effective date is set.
Given the extent of investor opposition documented in the comment file, a full shift to mandatory semiannual reporting appears more likely to result in either a scaled-back compromise or continued study rather than swift adoption — though the SEC’s ultimate direction remains uncertain.
The accounting profession is undergoing a fundamental structural transition as enterprise finance departments shift from periodic month-end closes toward automated continuous accounting models. By integrating specialized machine learning algorithms directly into enterprise resource planning (ERP) platforms, chief accounting officers are transforming financial reporting from a retrospective exercise into a real-time operational asset.
The Shift from Periodic Close to Continuous Financial Reporting
Traditional accounting workflows heavily relied on manual data reconciliation, spreadsheet calculations, and multi-week closing cycles at the end of each fiscal period. In contrast, continuous accounting frameworks utilize automated software agents to process, validate, and post transactional data in real time as business activities occur.
Automated bank reconciliation tools cross-reference incoming bank feeds, invoice records, and purchase orders automatically. By resolving transactional variances instantly throughout the month, corporate accounting teams eliminate the traditional workload spikes associated with quarterly and annual closes.
Machine Learning in Audit Trails and Anomaly Detection
Advanced natural language processing (NLP) and machine learning tools are redefining internal audit and financial control environments. Automated systems analyze 100% of general ledger entries, identifying anomalous transactions, duplicate payments, and unauthorized journal entries in real time.
Rather than relying on random statistical sampling, corporate internal auditors can focus their attention on high-risk flags automatically surfaced by algorithmic monitoring platforms. This continuous risk assessment strengthens internal controls over financial reporting (ICFR) and significantly reduces fraud risk.
Evolving Roles for Accounting Professionals
As routine data entry and manual reconciliation tasks become fully automated, the skill set required for accounting professionals is shifting toward data analysis, system design, and strategic business advisory.
– Systems Governance: Accountants are increasingly responsible for monitoring algorithmic accuracy and managing data integration pipelines.
– Business Partnership: Finance professionals leverage real-time financial dashboards to advise operational leaders on margin management and working capital allocation.
– Regulatory Compliance Management: Accounting teams utilize automated platforms to ensure compliance with dynamic tax codes and international accounting standards.
Core Implementation Recommendations
1. Deploy Automated Reconciliation Tools: Integrate continuous transaction processing modules into existing enterprise ERP architectures.
2. Establish Algorithmic Governance Controls: Implement strict internal testing protocols to ensure automated accounting rules comply with GAAP/IFRS standards.
3. Reskill Accounting Teams: Invest in training finance staff on data analytics, workflow automation, and predictive financial modeling.
