12 Essential Tax Law Changes You Need to Know

The One Big Beautiful Bill Act (OBBBA) has introduced significant changes to the tax landscape, making it crucial for individuals and business owners to understand how these modifications will affect their financial planning and tax obligations. Whether you’re a small business owner, investor, or household taxpayer, staying informed about these developments can help you optimize your tax strategy and maximize potential savings. This comprehensive guide breaks down the 12 most important tax law changes you should be aware of.

1. Extended Individual Income Tax Rates and Brackets

One of the most significant changes under the new tax law is the permanent extension of the individual income tax rates established by the 2017 Tax Cuts and Jobs Act (TCJA). Rather than allowing these rates to expire, the OBBBA makes them permanent, ensuring that taxpayers will continue to benefit from the lower tax brackets that have been in place since 2017. These rates represent a substantial reduction compared to pre-2017 levels, with taxpayers now paying 1 to 4 percent less per tax bracket across most income levels.

The permanent extension of these brackets provides certainty for long-term financial planning. Previously, taxpayers faced concerns about “tax cliffs” at the end of 2025, when many provisions were scheduled to expire. This extension eliminates that uncertainty and allows individuals and families to plan their finances with confidence that their tax rates will remain stable.

2. Increased Standard Deduction

The standard deduction has been nearly doubled compared to pre-2017 levels and remains significantly higher under the new law. For 2025, the standard deduction is $15,750 for single filers and more than $31,000 for couples filing jointly. Additionally, the OBBBA provides temporary increases of $2,000 for joint filers and $1,000 for individual filers through 2028, offering additional tax relief during these years.

Since the standard deduction is indexed annually for inflation, it will continue to grow each year, providing increasing benefits to taxpayers. This increased deduction means more income is sheltered from taxation, reducing the overall tax burden for millions of households.

3. Raised State and Local Tax (SALT) Deduction Cap

Previously capped at $10,000 per year, the state and local tax (SALT) deduction limit has been significantly increased under the new legislation. The OBBBA raises the SALT deduction cap to $40,000 for joint filers ($20,000 for married individuals filing separately) for the tax years 2025 through 2029. This adjustment provides substantial tax relief, particularly for high earners residing in states with elevated tax burdens.

However, this benefit comes with income limitations. The increased cap phases out for individuals with modified adjusted gross income (MAGI) exceeding $500,000, with the deduction reduction occurring at a rate of 30% for every dollar above this threshold. After 2029, the SALT deduction cap returns to its original $10,000 limit, making these years a critical window for affected taxpayers to plan their finances strategically.

4. Qualified Business Income (QBI) Deduction Increase

The QBI deduction, which allows owners of pass-through entities such as sole proprietorships and partnerships to deduct a portion of their qualified business income, has been permanently increased from 20% to 23% under the new law. This permanent enhancement enables business owners to reduce their taxable income more substantially, resulting in significant tax savings for qualifying enterprises.

However, it’s important to note that owners of specialized service trade or businesses (SSTBs) may continue to face certain limitations on this deduction. Despite these limitations for specific business types, the increase from 20% to 23% represents a meaningful improvement for most qualifying business owners, particularly those in non-service industries.

5. Enhanced Child Tax Credit

The child tax credit has been temporarily increased to $2,500 for tax years 2025 through 2028, up from the previous level. This temporary enhancement provides families with additional tax relief for each qualifying child, reducing their overall tax liability and improving cash flow during these years.

The temporary nature of this increase is important for families to understand in their long-term financial planning. While the higher credit offers substantial benefits through 2028, taxpayers should be aware that the credit will revert to its previous level beginning in 2029, which could affect household budgeting and tax planning strategies in subsequent years.

6. Trump Accounts for Children

A novel tax-advantaged savings vehicle has been introduced in the form of Trump Accounts for Kids, which allows families to make contributions to designated accounts for children born between 2025 and 2028. These accounts are designed to encourage family savings and provide tax benefits for funds set aside for children’s future needs.

This new savings mechanism reflects an effort to incentivize long-term savings and financial planning for younger generations. Families should consult with tax professionals to understand the specific rules, contribution limits, and tax treatment of these accounts to maximize their benefits.

7. Significantly Increased Estate Tax Exemption

The lifetime estate and gift tax exemption has been substantially increased to $15 million per individual ($30 million for married couples) as of January 1, 2026. This represents a major increase from the previously scheduled exemption amounts and provides significant relief for estate planning purposes, particularly for high-net-worth individuals and families.

This change is particularly important because the exemption was previously scheduled to be reduced by half in 2026 due to the expiration of TCJA provisions. The increase to $15 million provides certainty and allows families to plan their estates more effectively. It’s worth noting that gifts given before 2026 benefit from the already-high 2017 tax exemption, so families should review their estate plans in light of these changes.

8. Bonus Depreciation Extension for Business Assets

The new law reintroduces 100% bonus depreciation for qualified business assets acquired between January 20, 2025 and December 31, 2029. This provision allows companies to deduct the full cost of qualifying assets immediately rather than depreciating them over several years, providing significant immediate tax savings for businesses making capital investments.

For businesses planning to purchase equipment, machinery, or other operational assets during this window, the full bonus depreciation benefit can substantially reduce tax liability and improve cash flow. Companies should work with their tax advisors to identify qualifying assets and plan capital expenditures strategically to maximize these benefits.

9. Research and Development Incentives

The OBBBA suspends the required amortization of research and experimental expenditures for businesses from 2025 through 2029, allowing companies to claim immediate deductions for domestic research and development spending. This change encourages business innovation by permitting R&D costs to be deducted in the year incurred rather than being capitalized and amortized over time.

For businesses engaged in research, product development, and technological innovation, this provision offers meaningful tax benefits. By allowing immediate deductions for qualifying R&D expenses, the law reduces the after-tax cost of innovation and encourages companies to invest in research that drives competitive advantage and economic growth.

10. Pass-Through Entity Tax Treatment and Permanent Deductions

The new law provides permanent tax benefits for pass-through entities, including a permanent 20% small business deduction for entities such as partnerships and sole proprietorships. This permanent status provides long-term certainty for business owners, allowing them to rely on these deductions in their ongoing tax planning and financial projections.

Additionally, the permanent 100% bonus depreciation and full expensing provisions for business investments offer ongoing benefits for capital-intensive businesses. These permanent provisions contrast with temporary measures and signal the government’s commitment to supporting business investment and growth through sustained tax incentives.

11. Uneven Distribution of Tax Benefits

It’s important to understand that the benefits from the new tax law are not distributed evenly across all income levels. According to analyses by the Congressional Budget Office (CBO) and the Joint Committee on Taxation (JCT), individuals and families with higher incomes are expected to receive the most significant tax breaks. Meanwhile, many lower-income households might see their overall resources decrease, while middle-income families could experience small gains or losses depending on their individual circumstances.

This uneven distribution reflects the structure of the tax law, which includes provisions particularly beneficial to higher earners and business owners, such as the increased SALT deduction cap and enhanced business deductions. Lower-income households may benefit less from these provisions since they are less likely to itemize deductions or own businesses.

12. Changes to Renewable Energy Credits and Nuclear Energy Preferences

While many clean energy tax credits introduced in the Inflation Reduction Act face stringent phaseouts under the OBBBA, nuclear energy receives protected incentives. This represents a shift in tax policy toward nuclear energy while creating uncertainty for renewable energy developers relying on wind and solar resources.

Corporations focusing on renewable energy production may need to reevaluate investment plans due to the accelerated phaseout schedules and new leasing restrictions outlined in the OBBBA. Conversely, nuclear or domestic research and development companies gain competitive tax advantages under the new framework, potentially shifting investment patterns in the clean energy sector.

Important Timelines and Expiration Dates

Several provisions in the new tax law include sunset dates and phase-out schedules that taxpayers should understand:

• SALT Deduction Cap: Increases by 1% annually from 2025 through 2029, then returns fully to $10,000 for all taxpayers starting in 2030
• Child Tax Credit: The $2,500 credit applies only through 2028, reverting to previous levels in 2029
• Standard Deduction Increase: The temporary $2,000 and $1,000 increases apply through 2028
• Bonus Depreciation: The 100% bonus depreciation applies to assets acquired between January 20, 2025 and December 31, 2029
• R&D Expense Deduction: The suspension of amortization requirements applies from 2025 through 2029

Planning Considerations for Taxpayers

Understanding these tax law changes requires careful planning to maximize benefits. Individuals and business owners should consider:

• Reviewing itemized versus standard deduction strategies in light of the increased standard deduction and SALT cap changes
• Evaluating the timing of business investments to take advantage of bonus depreciation before the 2029 sunset
• Planning R&D spending during the 2025-2029 window to benefit from immediate deductions
• Reviewing estate plans to incorporate the new $15 million exemption level
• Assessing business structure and entity type to optimize QBI and pass-through entity deductions
• Consulting with tax professionals about the phase-out provisions that apply at higher income levels
