The 2026 Priority Guidance Plan: What Businesses Must Know
When major tax legislation passes, the public often assumes the work is complete. In reality, the passage of a bill is simply the opening chapter. For business owners, service-based entrepreneurs, and non-profits, the real work of understanding how these laws apply to daily operations is just beginning.
Earlier this month, the U.S. Department of the Treasury and the Internal Revenue Service released their 2026 Priority Guidance Plan. While this document may look like a routine administrative list, it serves as an essential roadmap. It outlines exactly where federal authorities intend to focus their regulatory energy—and where businesses should expect critical answers to emerge over the coming year.
This year’s plan is uniquely significant. It centers heavily on implementing the One Big Beautiful Bill Act (OBBBA), a sweeping piece of legislation with far-reaching implications. Simultaneously, it highlights a parallel effort to reduce administrative friction by streamlining or removing outdated tax regulations. At Hays CPA LLC, we analyze these plans closely to help our clients navigate what comes next with clarity and confidence.
Why Passing the Law Is Only the Beginning
Congress is responsible for drafting tax statutes, but legislative text rarely addresses every practical, real-world application. Instead, the law establishes a broad framework, leaving the Treasury and the IRS to define the specific mechanics through regulations, revenue procedures, notices, and administrative guidance.
These administrative rules determine how businesses calculate deductions, document compliance, claim tax credits, and make legal elections. Without this detailed guidance, businesses are left to interpret broad statutory language on their own while waiting for official clarification. That is why we monitor the regulatory agenda just as closely as the legislative process itself.
Treasury's Core Priority: Implementing the One Big Beautiful Bill Act
The 2026 Priority Guidance Plan confirms that implementing the OBBBA is the government's top administrative priority. Treasury expects to dedicate substantial resources to drafting regulations for key provisions that directly impact business owners, investors, and high-impact organizations, including:
- Research and development (R&D) expensing rules
- Bonus depreciation guidelines
- Section 163(j) business interest limitation rules
- Opportunity Zones regulations
- Foreign tax credit adjustments
- Trump Accounts provisions
- Remittance-transfer excise tax rules
- Additional technical provisions embedded within the legislation
Each of these focus areas will shape future investment decisions, recordkeeping requirements, and tax compliance strategies. For business owners, the practical takeaway is clear: the full utility of the planning opportunities created by the OBBBA will remain partially obscured until the Treasury clarifies how it intends to administer these provisions. Effective tax planning must remain flexible and adaptive as these details emerge.
Simplifying Compliance by Reducing Unnecessary Regulations
In addition to drafting new rules, the Treasury’s 2026 agenda emphasizes a commitment to deregulation. The plan identifies several initiatives designed to simplify compliance and eliminate outdated administrative burdens, including:
- Phasing out obsolete tax regulations
- Withdrawing specific partnership-related party basis-shifting regulations
- Simplifying capitalization rules under Section 263A
- Increasing information-reporting thresholds
- Executing additional projects focused on reducing administrative friction
While streamlining the tax code is a welcome shift, it introduces its own set of challenges. As older regulations are modified, withdrawn, or replaced, historical guidance may no longer align with current law. Relying on outdated planning strategies, older online articles, or historical advice becomes increasingly risky during periods of regulatory transition.
An Unexpected Transition: The Departure of Ken Kies
While the Treasury has set forth an ambitious agenda, a major personnel shift could influence both the speed and execution of these regulatory projects. Shortly after the guidance plan was published, Ken Kies departed from the Treasury.
Within the tax profession, this transition is highly significant. As the Assistant Secretary for Tax Policy, Kies led the Office of Tax Policy and held a senior leadership role within the Office of Chief Counsel. These positions put him at the very center of federal tax policy development and regulatory drafting.
Whenever complex technical challenges arose, or when competing policy goals required coordination between the Treasury and the IRS, Kies was a central figure in resolving those discussions. He represented a deep reservoir of institutional knowledge and tax policy experience.
Implementing a comprehensive law like the OBBBA requires more than just technical drafting; it demands leaders who can coordinate complex agencies, resolve technical disputes, and shepherd massive regulatory packages to completion. Replacing that level of leadership is a process that takes time.
What This Personnel Shift Means for Timeline and Execution
This leadership transition does not mean the Treasury’s priorities will change. The projects outlined in the Priority Guidance Plan remain the agency's formal agenda. However, changes in leadership frequently alter resource allocation, timelines, and decision-making speed.
Some highly anticipated regulations may experience delays, while other projects may undergo additional layers of review or modification before publication. For business owners and entrepreneurs, this means patience is necessary. Getting definitive answers on some of the OBBBA's more complex provisions may take longer than initially expected.
The Evolutionary Nature of Tax Guidance
It is important to remember that tax guidance rarely arrives in a single, finished package. The administrative process is iterative. Typically, the Treasury begins by issuing initial notices. These are often followed by proposed regulations, which are then subject to public comment. After evaluating feedback, the agency issues revised final regulations, which may still be followed by technical corrections.
As this multi-stage process unfolds, the official interpretation of the law can evolve significantly. A tax position that seems reasonable today might require adjustment after the final regulations are published. Regularly reviewing your long-term financial strategies is critical to ensuring they remain aligned with these ongoing adjustments.
Why Relying on Historical Guidance Can Be Risky
Because the Treasury is actively working to reduce regulatory complexity, many existing rules are being rewritten or retired. A strategy that worked perfectly several years ago may no longer be valid under the emerging regulatory framework. This is not because the original advice was incorrect, but because the rules of the game are shifting. Part of our role as strategic advisors is ensuring that your business decisions are guided by today's active rules, not yesterday's obsolete guidelines.
Our Commitment to Keeping Your Business Ahead
Most taxpayers naturally focus on the legislative process and the headline-grabbing bills passed by Congress. Our team at Hays CPA LLC goes a step deeper. We track the mechanics of how the Treasury and the IRS interpret and enforce those laws, as these details dictate how deductions are documented, how compliance is maintained, and how long-term goals are realized.
Over the coming year, we will be closely monitoring the release of proposed regulations, notices, and procedural updates affecting business deductions, international transactions, reporting requirements, and the various benefits of the OBBBA. We will also watch for deregulatory changes that could alter your current compliance workflows.
Navigating Your Next Steps with Hays CPA LLC
The passage of the One Big Beautiful Bill Act was only the first step in a long process. With the 2026 Priority Guidance Plan, the Treasury has set its course, but leadership transitions mean the timeline for final regulations remains fluid. As these rules are finalized, long-standing tax positions may need to be updated to match the shifting regulatory landscape.
If you are planning a significant business transaction, restructured investment, entity modification, or other major tax move, relying on past assumptions is a substantial risk.

Staying ahead of tax law is not just about knowing what Congress passed—it is about understanding how those laws will actually be enforced.
