AICPA Urges IRS to Prioritize Tax Simplification in 2026–2027 Guidance Plan
In a comprehensive effort to bridge the gap between complex federal tax statutes and their practical application, the American Institute of CPAs (AICPA) has submitted nearly 200 formal recommendations to the Internal Revenue Service (IRS) regarding the agency’s 2026–2027 Priority Guidance Plan. This massive undertaking reflects the organization’s ongoing commitment to tax simplification and the reduction of administrative burdens on taxpayers and practitioners alike.
The submission, finalized and sent to the IRS on May 13, arrives in response to Notice 2026-23, through which the IRS invites public input annually to help shape the regulatory and administrative agenda for the upcoming fiscal cycle. By identifying, ranking, and detailing 10 critical technical areas, the AICPA aims to provide the IRS with a roadmap for addressing the most pressing ambiguities currently facing the accounting and tax profession.
The Mandate for Clarity: A Chronology of Advocacy
The annual Priority Guidance Plan is a cornerstone of the IRS’s administrative function. It serves as the formal mechanism through which the agency signals its intent to issue regulations, revenue rulings, revenue procedures, and notices. For the 2026–2027 cycle, the IRS sought recommendations that would not only interpret the law but also improve the efficiency of tax administration.
The AICPA’s involvement is a multi-stage process that begins long before the letter is submitted in May. It involves the collaboration of 10 specialized technical panels, each composed of veteran tax practitioners, researchers, and policy advocates. These panels spend months reviewing recent legislative developments, identifying areas where taxpayers have expressed confusion, and evaluating the "real-world" friction points that hinder compliance.
Once these points of friction are identified, the panels draft detailed memoranda. These drafts are then vetted by the AICPA’s Tax Policy and Advocacy team to ensure consistency with broader organizational goals, such as the promotion of tax simplification and the mitigation of penalties for inadvertent errors. The final submission is not merely a list of grievances; it is a prioritized, evidence-based document designed to help the IRS allocate its limited resources toward the areas that will have the most significant positive impact on the American tax system.
Strategic Focus: The 10 Pillars of Guidance
The AICPA’s 193 recommendations are categorized into 10 key technical areas. While the full scope of the submission covers a wide array of sub-issues, the top priority for each panel underscores the technical depth required to fix the modern tax landscape.
1. Corporations and Shareholders
The primary focus here is the Corporate Alternative Minimum Tax (CAMT) under Sec. 55. The AICPA has urged the IRS to finalize guidance regarding key definitions, particularly those involving mergers and acquisitions. There is significant uncertainty regarding the definition of an "applicable corporation" under Sec. 59(k) and the calculation of "adjusted financial statement income" under Sec. 56A. Without precise definitions, corporations face severe risks of underpayment or non-compliance during complex restructuring events.
2. Employee Benefits
The AICPA is pushing for a new revenue procedure to implement Section 305 of the SECURE 2.0 Act of 2022. This legislation, which aims to expand the Employee Plans Compliance Resolution System (EPCRS), is critical for plan administrators. By clarifying the path for correcting plan errors, the IRS can encourage better compliance without resorting to punitive measures that discourage employers from maintaining retirement programs.
3. Exempt Organizations
For tax-exempt entities, the focus remains on Sec. 4960. The AICPA suggests specific transition relief for fiscal-year filers and calls for an extension of exceptions for limited hours, nonexempt funds, and limited services. Perhaps most notably, the AICPA has requested a regulatory exception to prevent unpaid public volunteers from being classified as "covered employees," a designation that currently creates unintended administrative burdens for non-profits.
4. Individual and Self-Employed Tax
The ongoing frustration with the state and local tax (SALT) deduction cap under Sec. 164 continues to be a top concern. The AICPA is seeking clearer guidance on the application of this cap, particularly for taxpayers navigating complex state-level workarounds and multi-jurisdictional filings.
5. International Tax
The AICPA has requested comprehensive guidance regarding the 2026 effective dates of provisions found in the "One Big Beautiful Bill Act" (H.R. 1, P.L. 119-21). As global tax rules become increasingly interconnected, practitioners require timely clarity to plan for cross-border investments and ensure compliance with shifting international standards.
6. IRS Advocacy and Relations
Perhaps the most foundational request involves the modernization of penalty regulations. The AICPA has urged the IRS to issue new regulations regarding accuracy-related penalties under Sec. 6662, 6662A, and 6664. Many of the existing regulations for these sections have not seen a significant update since 1997, leaving them woefully out of sync with current digital filing realities and modern enforcement standards.
7. Partnership Tax
The partnership tax landscape is currently dominated by concerns over basis-shifting transactions. The AICPA is advocating for the finalization of proposed regulations (REG-108921-25) to withdraw Regs. Sec. 1.6011-18. This move is essential to clarify the regulatory environment and remove outdated rules that no longer align with current anti-abuse initiatives.
8. S Corporation Tax
S corporations often fall victim to inadvertent terminations or invalid elections. The AICPA has requested a revenue procedure that would modify current automatic relief, allowing taxpayers to rely on multiple revenue procedures simultaneously to resolve various issues affecting their S corporation status. This "stacking" of relief would significantly streamline the correction process.
9. Tax Methods and Periods
The definition of "qualified real property" under Sec. 179 remains a point of contention. The AICPA is seeking specific guidance on the types of assets that qualify for expensing, which would provide small business owners with the certainty needed to make capital investments and leverage tax incentives effectively.
10. Trust, Estate, and Gift Tax
This panel continues to focus on the interplay between shifting asset values and federal transfer taxes. While the specifics remain technical, the overall goal is to harmonize existing guidance with current economic conditions to prevent double taxation or unintended valuation penalties.
Implications for the Accounting Profession
The implications of the AICPA’s submission are profound. For the practitioner, the current environment is defined by "guidance lag"—the period between the enactment of a law and the issuance of clear, usable administrative rules. When the IRS fails to provide timely guidance, practitioners are forced to make conservative estimates, which can lead to overpayment, or aggressive interpretations, which can lead to audit exposure.
Kristin Esposito, director of Tax Policy & Advocacy at the AICPA, emphasized the practical stakes in a recent news release: "The recommendations ensure that the IRS guidance reflects practical, real-world application for taxpayers and practitioners. Given that our recommendations are ranked by priority within each area, we encourage a focus on the highest-priority items."
By streamlining these processes, the IRS can improve its own operational efficiency. A reduction in technical inquiries and audit disputes—driven by clearer guidance—allows the agency to focus its enforcement resources on high-risk areas, such as tax evasion and organized fraud, rather than spending time resolving disputes caused by ambiguous regulatory language.
Supporting Data and the Push for Simplification
The AICPA’s call for tax simplification is not merely a request for fewer rules, but for more coherent ones. The 193 recommendations serve as a "bottom-up" diagnostic of the U.S. tax code. When analyzed in aggregate, these suggestions reveal a system that has grown organically and sporadically over decades, often resulting in conflicting requirements that defy logical integration.
The push for simplification includes:
- Harmonization of Definitions: Aligning terms across different sections of the Internal Revenue Code to ensure that a term like "qualified property" has a consistent meaning.
- Procedural Consolidation: Reducing the number of forms and disparate procedures required to correct common errors, such as those related to S corporation elections.
- Modernization of Penalty Frameworks: Bringing regulations from the pre-internet era into the modern age, reflecting how data is actually processed and stored today.
Looking Ahead: The Path to 2027
The IRS will now review the AICPA’s submissions, along with those from other professional organizations, academic institutions, and taxpayer advocacy groups. The publication of the final 2026–2027 Priority Guidance Plan will be the next major milestone.
While the AICPA acknowledges that the IRS faces significant budgetary and staffing constraints, the organization maintains that the investment in high-quality, clear guidance yields significant returns in the form of improved voluntary compliance. As the agency continues its transition toward a more digitized, service-oriented model, the integration of these practical recommendations will be a critical litmus test for the IRS’s ability to serve the modern American taxpayer.
For tax professionals, the coming year will be defined by how the IRS responds to these requests. Whether the agency adopts these specific recommendations or takes a different path, the AICPA’s submission has successfully set the agenda for the conversation on what "fair and efficient" tax administration looks like in the 21st century.
