The Real Story After Tax Reform: Why the Rules of the Road Are Still Being Written
When major tax legislation passes, it is easy to assume the hard part is over. In reality, the passage of a bill is just the opening bell. The actual impact on your business is determined by what happens next.
Recently, the U.S. Department of the Treasury and the Internal Revenue Service released their 2026 Priority Guidance Plan. While this document might look like standard bureaucratic paperwork to the untrained eye, it serves as a vital roadmap. It shows exactly where the Treasury department plans to focus its administrative energy over the coming year—and where critical answers will finally emerge for taxpayers.
This year’s agenda carries immense weight. Its primary objective is laying out the implementation of the One Big Beautiful Bill Act (OBBBA), one of the most comprehensive pieces of tax legislation enacted in recent memory. At the same time, the plan highlights a parallel initiative to strip away outdated, complex, or unnecessary tax regulations. For business owners, the message is clear: the rules are actively being rewritten, and the final details are still some distance away.
The Long Road from Legislation to Compliance
Congress is responsible for drafting and passing tax laws, but those statutory texts rarely answer every practical, real-world question.
Instead, a new statute provides a broad framework. It is up to the Treasury and the IRS to fill in the blanks by issuing regulations, revenue procedures, notices, and other administrative guidelines that explain how those laws operate in real-world scenarios.
These administrative rules dictate the fine details of how your business complies: how you calculate deductions, make tax elections, document expenses, claim credits, and structure transactions. The statute outlines what Congress wants to achieve, but the regulations establish the exact mechanics of how taxpayers must comply.
Until these official interpretations are published, many taxpayers are left navigating broad statutory language without a definitive guide. This is why our team monitors the Treasury’s regulatory pipeline just as closely as the legislative votes in Washington.
Unpacking the Treasury's Core Focus: The OBBBA
The 2026 Priority Guidance Plan makes it clear that implementing the One Big Beautiful Bill Act is the government's top priority.
The Treasury is dedicating significant resources to drafting regulations for provisions that business owners and investors have been watching closely. Key target areas include:
- Research and development (R&D) expensing rules
- Bonus depreciation mechanics
- Section 163(j) business interest limitation rules
- Opportunity Zone regulations
- Foreign tax credit adjustments
- Trump Accounts
- Remittance-transfer excise tax provisions
- A wide range of technical provisions embedded within the new law
Each of these rule-making projects will directly impact tax planning, reporting requirements, recordkeeping, and future investment decisions. For business owners, this means that many of the planning opportunities introduced by the OBBBA cannot be fully optimized until the Treasury explains exactly how they will be administered. While planning shouldn't halt, it must remain highly flexible to adapt as these official guidelines roll out.
The Parallel Push to Reduce Regulatory Complexity
Alongside drafting new guidelines, the Treasury's 2026 agenda includes a major effort to streamline the existing tax code by simplifying or eliminating redundant regulations.
These deregulatory initiatives specifically target:
- The elimination of unnecessary tax regulations
- The withdrawal of specific partnership-related party basis-shifting regulations
- The simplification of capitalization rules under Section 263A
- Increasing information-reporting thresholds
- Various other projects designed to ease administrative burdens on businesses
While reducing red tape is a welcome development, it introduces a practical risk for taxpayers. As old rules are altered, withdrawn, or replaced, previously reliable guidance becomes obsolete. Strategy and advice that served your business well a few years ago might no longer apply. Relying on outdated internet articles or historical planning methods is increasingly risky in an environment of rapid regulatory change.
A Leadership Shift: The Impact of Ken Kies’ Departure
Though the Treasury’s regulatory agenda is highly ambitious, a major personnel change could disrupt its timeline and execution.
Shortly after releasing the priority guidance plan, Ken Kies departed from his post at the Treasury.
While his name may not be familiar outside of professional tax circles, his exit attracted immediate attention within the tax community. Ken Kies served as the Assistant Secretary for Tax Policy—leading the Office of Tax Policy—and also held a senior leadership role within the Office of Chief Counsel. These responsibilities placed him at the very center of federal tax policy and regulatory enforcement.
Whenever difficult technical disputes arose, competing policy objectives needed balancing, or major regulatory rollouts required coordination between the Treasury and the IRS, Kies was a central figure in those discussions. Replacing that level of deep institutional knowledge and leadership is not a quick or simple task. Successfully implementing legislation as massive as the One Big Beautiful Bill Act requires leaders who can navigate complex agency disputes and move projects from draft to final publication.
Expect Delays in the Regulatory Timeline
While the overall priorities outlined in the Priority Guidance Plan remain intact, leadership transitions inevitably shift timelines and resource allocations.
Some regulations may move more slowly than originally planned. Other rules may undergo additional layers of review or be revised entirely as new leadership steps in to evaluate pending policy decisions. For taxpayers, this means that patience will be required as we wait for final, definitive answers on key provisions of the new law.
The Multi-Stage Evolution of Tax Guidance
It is important to remember that tax guidance is rarely delivered all at once. It typically follows a gradual, multi-step process.
First, the Treasury may release preliminary notices. These are often followed by proposed regulations, which are then opened for public comment. After reviewing industry feedback, the Treasury issues revised final regulations, which can still be followed by technical corrections.
As this multi-stage process unfolds, tax interpretations can shift significantly. An interpretation that seems logical right after a bill is passed may look very different by the time the final regulations are written. This makes it vital to periodically revisit tax planning strategies to ensure they align with the most current guidance.
Why Historical Tax Strategies May Fail Today
Because the Treasury is actively working to eliminate obsolete regulations, strategies built on old guidance may no longer protect you.
This doesn’t mean your past planning was wrong; it simply means the legal landscape has moved on. One of the most important roles of a proactive tax partner is identifying when historical guidance is no longer valid in the current regulatory environment.
Proactive Monitoring for Your Peace of Mind
While most business owners focus entirely on the bills that Congress passes, our team at Ez Tax Preparation watches the regulatory pipeline.
We track how the Treasury and the IRS interpret and enforce these laws because those details dictate how your deductions are documented, how compliance is met, and how strategies are executed.
Over the coming year, we will be tracking a continuous stream of proposed regulations, notices, and guidelines affecting business deductions, international rules, Trump Accounts, and other provisions of the One Big Beautiful Bill Act, alongside ongoing deregulatory updates.
Navigating Evolving Rules with Confidence
The One Big Beautiful Bill Act has changed the tax landscape, but its practical implementation is just getting underway. With Treasury priorities set, but leadership changes introducing potential timeline delays, taxpayers must remain both patient and proactive. Evolving guidance means yesterday's assumptions may not hold up under today's rules.
If you are planning major business transactions, entity restructuring, or significant tax decisions, relying on outdated advice is a major risk.
