Tax Rules Are Shifting in 2026

Big 2026 Tax Changes and Strategies for Individuals and Businesses: The Latest Developments You Need to Know

As 2026 approaches, the U.S. tax landscape continues to undergo unprecedented transformation, driven by sweeping federal reforms, evolving state policies, operational challenges at the IRS, and sector-specific initiatives. These developments collectively create a complex environment that requires proactive planning, strategic adjustments, and vigilant monitoring by individuals and businesses alike. Recent updates and legal rulings have amplified both the opportunities and uncertainties ahead, emphasizing the importance of staying informed to optimize benefits and mitigate risks.

Major Federal Tax Reforms for 2026: What’s Changing and Why It Matters

1. Mandatory Roth Catch-Up Contributions for High-Income Earners

Starting in 2026, taxpayers earning over approximately $250,000 annually must convert their catch-up retirement contributions into Roth accounts. This legislation eliminates the pre-tax option for high earners, encouraging tax-free growth of retirement savings and aiming to increase revenue from the wealthiest. The policy also promotes tax diversification for retirement planning.

Implications and strategies:

Review current retirement plans: High-income individuals should analyze existing contributions and plan conversions accordingly.
Staged conversions: To manage tax impacts, consider spreading conversions over multiple years.
Income and timing considerations: Engage in tax-efficient timing strategies to limit immediate tax burdens.
Professional guidance: Collaborate with financial advisors to tailor strategies aligned with these new rules.

2. Proposed Reforms to Capital Gains and Investment Strategies

Legislators are actively debating raising long-term capital gains tax rates, primarily targeting high-net-worth investors. Additionally, efforts to close loopholes such as the Net Unrealized Appreciation (NUA) benefit—used in estate and investment planning—are gaining momentum.

Potential impacts:

Timing asset sales: Investors are advised to realize gains before reforms become law.
Portfolio reassessment: Strategies like loss harvesting and rebalancing should be employed to optimize tax outcomes.
Estate planning: Use trusts, gifting, and other mechanisms to protect wealth amid potential tax increases.

3. Tightening Deduction Rules and Expanding Tax Credits

The IRS is tightening itemized deduction rules, including limits on miscellaneous deductions, more restrictive mortgage interest deductions, and stricter charitable contribution regulations. Concurrently, eligibility thresholds for credits like the Child Tax Credit and Earned Income Tax Credit (EITC) are becoming more restrictive, especially for higher-income or less-qualified taxpayers.

Strategic actions:

Maximize contributions to tax-advantaged accounts such as Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs).
Early income and deduction planning can help optimize credits and avoid disqualification due to income thresholds.

4. Changes to Federal Retirement Accounts

Recent announcements in late 2025 introduced new contribution limits and distribution rules affecting 401(k) plans. These modifications require review and adjustment of retirement strategies to maximize growth and tax advantages.

Key takeaway:

Align your retirement plans with new caps and rules to maximize savings and tax benefits.

5. Estate and Gift Tax Uncertainties

While the estate tax exemption is projected to increase with inflation, ongoing legal debates—such as recent reversals by the Fifth Circuit Court—highlight uncertainties around estate transfer rules, partnership taxation, and gift policies.

Estate planning tips:

Update estate documents and trusts to reflect current laws.
Use strategic gifting and trust structures to reduce estate liabilities and streamline wealth transfer.

Operational and Procedural Developments Impacting Taxpayers

1. Clarification on Self-Employment Income for Limited Partners

A January 2026 legal ruling clarified that state law limited partners are subject to self-employment income rules under federal law. This significantly impacts partnership income reporting, prompting many partnerships to reevaluate structures to avoid unexpected liabilities.

Key action:
Taxpayers involved in partnerships should conduct detailed income analyses and review partnership agreements to prevent surprises at tax time.

2. IRS Staffing Declines and Backlogs

The 27% decline in IRS staffing—a direct consequence of recent budget constraints—has led to significant delays, service disruptions, and backlogs. Reports emphasize the importance of filing early, meticulous record-keeping, and using updated electronic filing systems to avoid penalties.

Recent data:

Refunds are nearly 11% higher this year, partly due to early filings and policy adjustments.
Processing times are longer, with some filers experiencing delays of 4-6 weeks, compared to the usual 2-3 weeks.

3. IRS Guidance for the 2026 Filing Season

The IRS emphasizes early filing and meticulous record-keeping, especially for seniors and retirees. Recent guidance clarifies reporting obligations related to partnership income, self-employment, and complex income streams.

4. IRS Regulatory Updates and Guidance

Recent semi-permanent regulatory updates focus on early filing and accurate reporting amid operational constraints. Clarifications include reporting requirements for partnership income and self-employment, affecting complex filers.

5. Impact of Reduced IRS Workforce

With approximately 27% of IRS staff lost due to budget cuts, longer refund delays, audit activity, and service quality issues are expected to persist through 2026. Experts warn that audit strategies may become more aggressive for high-net-worth individuals and complex filings.

Recommendations:

File early to mitigate delays.
Maintain detailed records.
Partner with experienced tax professionals to navigate delays and reduce audit risks.

State and Local Policy Divergence and New Opportunities

1. Partial Decoupling from Federal Law

States like Oregon are passing legislation to partially decouple from federal law changes, aiming to protect revenue streams. The Oregon Senate’s February 16 approval of a plan to limit conformity results in divergent tax treatments across jurisdictions, complicating multistate planning.

Implications:

Residents and businesses must tailor strategies to state-specific laws to manage liabilities effectively.

2. Proposed Wealth and Income Taxes

States including California and Washington are considering proposals for wealth taxes—such as a 5% net worth tax on assets exceeding $1 billion—and income tax reforms. These initiatives could prompt high-net-worth individuals to reconsider domicile and engage in advanced planning.

Potential effects:

The "tax death spiral"—where high taxes incentivize residents to relocate—may accelerate, impacting state revenues and policies.

3. State-Specific Updates

Louisiana: Governor Jeff Landry recently discussed tax season updates during a news conference, emphasizing new filing procedures and state credits to support residents amid federal reforms.
South Carolina: Recent law changes include adjustments to state income tax brackets, expansion of certain credits, and revisions to deductions to better align with federal policies, prompting residents to review their filings.

4. Scrutiny of Data Center Tax Breaks and Property Tax Reforms

Some states, such as Oregon and New York, are reconsidering incentives like data center tax breaks offered to attract infrastructure investments. After years of generous incentives, public scrutiny and budget pressures are prompting potential rollbacks and policy shifts.

Additionally, property tax reforms—aimed at easing homeowner burdens—are actively being pursued to address rising home values and local fiscal pressures.

Sector-Specific and International Policy Developments

1. Treasury Guidance on Clean Energy Credits & Foreign Involvement

The Treasury Department has issued interim guidance concerning foreign influence restrictions on clean energy projects. Projects involving Foreign Entities of Concern (FEOC) may lose eligibility or face penalties, particularly in solar, wind, and clean fuels sectors.

Implications:

Domestic sourcing and transparency are critical for maximizing credits.
Companies should structure projects carefully to avoid compliance issues.

2. R&D and Section 174 Clarifications

The IRS and professional associations anticipate new guidance on Section 174A(c), which relates to capitalization and amortization of R&D expenses. This will significantly impact technology, pharmaceutical, and engineering firms planning research investments.

Impact of recent CAMT guidance:

The Checkpoints News article dated February 26, 2026, highlights clarifications that clarify which R&D expenses are eligible for amortization versus immediate expensing.
This guidance aims to streamline compliance and provide clarity amid complex rules, ultimately affecting cost recovery strategies and tax planning for innovation-intensive industries.

3. Bonus Depreciation and Qualified Property Rules

Interim guidance clarifies definitions of qualified property eligible for bonus depreciation, especially for clean energy assets and advanced manufacturing equipment, providing opportunities to maximize depreciation benefits in 2026.

Practical Action Items and Recommendations

File early: To avoid delays and backlogs caused by reduced IRS staffing.
Review and update your retirement and estate plans considering new laws, rulings, and inflation-adjusted exemptions.
Assess foreign involvement: Ensure compliance with Treasury guidance on clean energy projects involving foreign entities.
Maintain meticulous records: To streamline audits and reduce penalties.
Consult experienced advisors: For navigating operational delays, tax strategy adjustments, and multistate planning.
Reevaluate asset transfer strategies: Such as adding someone to bank accounts or gifting, with a focus on gift and estate implications under new rules.

Current Status and Implications

Despite the 27% decline in IRS staffing, efforts toward modernization and reform are ongoing. However, refund delays, audit activity, and service disruptions are expected to persist into 2026—especially for complex or high-net-worth filings. These reforms offer opportunities for wealth management, estate planning, and tax mitigation but demand early action and strategic agility.

The key takeaway: Proactive planning, early filing, and partnering with experts remain essential to maximize benefits and navigate risks effectively in this evolving tax landscape.

Final Thoughts

The approaching 2026 reforms represent a historic shift—offering both opportunities and challenges. The landscape is marked by legal uncertainties, operational hurdles, and diverging state policies, demanding vigilance and adaptability.

Those prepared—by staying informed, reviewing plans, and engaging professionals—will be best positioned to thrive in this new era. Early action and ongoing monitoring are crucial to maximize benefits and minimize risks during this transformative period of tax reform.
