The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, represents a massive overhaul of the U.S. tax code.  While it makes many provisions of the 2017 Tax Cuts and Jobs Act permanent, it also introduces several new deductions and credits for 2026 that shift how high earners and non-itemizers alike approach tax planning.  Below are some of the more noteworthy provisions.

 

Enhanced Senior and SALT Deductions

  • The Change: Taxpayers aged 65 and older can now take an additional $6,000 “Senior Bonus Deduction” ($12,000 for couples), which applies even if you take the standard deduction.  Additionally, the State and Local Tax (SALT) deduction cap has been raised significantly from $10,000 to $40,000 for most taxpayers.
  • How to Take Advantage: If you are a senior, this bonus deduction can be used to further offset taxable income like Social Security.  For the SALT increase, taxpayers in high-tax states with incomes under $500,000 should review whether itemizing now provides a better return than the increased standard deduction.

 

Permanent Business and R&D Expensing

  • The Change: The bill restores and makes permanent 100% bonus depreciation for qualified business equipment.  It also allows businesses to immediately deduct domestic research and experimental (R&D) costs rather than amortizing them over five years.
  • How to Take Advantage: Business owners should consider accelerating equipment purchases or R&D projects to 2026 to take the full deduction in a single year.  Small businesses with under $31 million in receipts may even be able to apply these R&D rules retroactively to 2022.

 

Expansion of HSA and 529 Plans

  • The Change: Starting in 2026, bronze and catastrophic health plans are now HSA-compatible, allowing more people to open and fund Health Savings Accounts.  For education, 529 plan distribution limits for K-12 expenses have doubled to $20,000 per year.
  • How to Take Advantage: If you hold a bronze-level insurance plan, you can now contribute to an HSA for triple-tax advantages.  Families with students in private K-12 schools can now withdraw larger tax-free amounts from 529 plans to cover tuition, tutoring, and technology.

 

New Charitable Deduction for Non-Itemizers

  • The Change: Beginning in 2026, the OBBBA introduces a permanent “above-the-line” deduction for those who take the standard deduction.  You can deduct up to $1,000 ($2,000 for joint filers) for cash contributions made directly to qualified 501(c)(3) organizations.

 

New Charitable Deduction for Itemizers

  • The Change: The 0.5% Floor: In 2025, itemizers could deduct their first dollar of charitable giving.  In 2026, a new 0.5% of Adjusted Gross Income (AGI) floor applies, meaning only donations above that threshold are deductible. 

     Real-World Example: An individual with an AGI of $200,000 donates $5,000 to charity:

     o   In 2025: They deduct the full $5,000.

     o   In 2026: Their floor is $1,000 (0.5% of $200k).  They can only deduct the portion above that floor, resulting in a $4,000 deduction ($5,000 total - $1,000 floor)

  • The Change: The 35% tax bracket cap: High-income earners in the top (37%) tax bracket also see a reduction in the "value" of their deduction. In 2025, a $1,000 donation saved them $370 in taxes $1,000 x 37%).  In 2026, that same gift’s benefit is capped at 35%, saving them only $350. 

     Real-World Example: The Miller Family, a high-earning couple in the 37% tax bracket, has an AGI of $800,000 and donate $40,000 to charity in 2026.

     o   The 0.5% Floor: Because they itemize, the first 0.5% of their AGI is "non-deductible."

          Calculation: $800,000 x 0.005 = $4,000.

          Only the amount above $4,000 is eligible to be deducted.

          Eligible Deduction: $40,000 - $4,000 = $36,000.

     o   The 35% Benefit Cap: Even though they are in the 37% tax bracket, the OBBBA limits the tax savings on charitable gifts to 35%.

          Old Way (2025): A $40,000 donation would have saved them $14,800 ($40,000 x 37%).

          New Way (2026):  Lose the first ½ percent and the remaining benefit is capped at 35%.

          Actual Tax Savings: Reduced $36,000 deduction x 35% = $12,600.

     o   Total tax benefit drops by roughly $2,200 between the floor (losing the first $4,000 of their gift) and the cap (losing 2% of the tax-saving power), comparing to the old rules.

  • A solution: The Millers might choose to "bunch" two years of giving into one to clear that $4,000 floor only once.

 

New Itemized Deduction Cap (The "Haircut")

  • The Change: The OBBBA officially repeals the old limitation and replaces it with a new "haircut" for high earners.  All itemized deductions are reduced by 2/37ths of the amount your taxable income exceeds the top (37%) tax bracket threshold. 

     If you are in the 37% tax bracket, your total allowable itemized deductions are reduced by the lesser of: 

     o   2/37 of your otherwise allowable itemized deductions.

     o   2/37 of your taxable income (calculated before deductions) that exceeds the 37% bracket threshold. 

     The result is that your deductions provide a tax benefit equivalent to the 35% bracket (37% marginal rate minus the 2% reduction). 

     2026 Example: A married couple has $1,000,000 in taxable income (before deductions) and $100,000 in otherwise allowable itemized deductions. 

     o   Calculate the Income over 37% threshold: $1,000,000 - $768,700 = $231,300

     o   Compare the two deduction-haircut calculations to find the lesser

               Deduction-based:  2/37 x $100,000 = $5,405

               Income-based:  2/37 x $231,300 = $12,503

     o   Final Allowable Deduction: $100,000 - $5,405 = $94,595

     o   Verify that the deductions provide a tax benefit equivalent to the 35% bracket:

               Haircut: $94,595 x 37% = $35,000 

               Original: $100,000 x 35% = $35,000

  • How to Take Advantage: If your income is well into the 37% bracket, the value of your itemized deductions will decrease.  To counter this, prioritize "above-the-line" adjustments that lower your AGI directly, such as maxing out 401(k) contributions or utilizing the new HSA eligibility for bronze-level health plans.

 

Permanent Qualified Business Income (QBI) Deduction

  • The Change: The 20% QBI deduction (Section 199A), which allows eligible self-employed individuals and small business owners to deduct up to 20% of their qualified business income, has been made permanent.
  • How to Take Advantage: Because this deduction is now permanent, you can make long-term capital investments in your business without the fear of the tax benefit expiring.  Review your business structure with a tax professional to ensure you meet the specific wage and property requirements that apply at higher income levels. 

 

Permanent Estate Tax Exemption

  • The Change: The OBBBA prevents the "sunset" of the high estate tax exemptions.  For 2026, the individual exemption is set at $15 million ($30 million for married couples) and will continue to be indexed for inflation annually.
  • How to Take Advantage: This permanence eliminates the need for "use it or lose it" gifting strategies that many planned for 2025. However, you should still utilize annual exclusion gifts (currently $19,000 per recipient) to reduce your taxable estate over time while maintaining the large lifetime exemption for your primary assets. 

 

No Tax on Tips and Overtime

  • The Change: Starting in 2025 and continuing through 2028, workers in "customary" tipped occupations can deduct up to $25,000 of qualified tip income from their federal taxes.  Similarly, a "No Tax on Overtime" provision allows a dollar-for-dollar deduction of up to $12,500 for qualified overtime pay ($25,000 for joint filers).
  • How to Take Advantage: Ensure your employer correctly designates these earnings on your Form W-2.  Both deductions begin to phase out if your Modified Adjusted Gross Income (MAGI) exceeds $150,000 ($300,000 for joint filers).

 

Car Loan Interest Deduction

  • The Change: For the first time, individuals can deduct up to $10,000 in interest paid on loans for new, personal-use vehicles.  To qualify, the vehicle must have its final assembly in the United States.
  • How to Take Advantage: If you're car shopping in 2026, check the vehicle's VIN and assembly label to ensure it qualifies.  This deduction is available even to those who do not itemize, but it phases out for single filers earning over $100,000 ($200,000 joint).

 

Rising Impact on AMT (Alternative Minimum Tax)

  • The Change: While the OBBBA retains the higher AMT exemption thresholds and phase-outs introduced by the TCJA, it also introduces several new deductions (like the Senior and Auto Loan deductions) that are not deductible for AMT purposes.
  • The Risk: As you claim more of these new "Beautiful Bill" deductions, you are more likely to trigger the AMT, which essentially acts as a shadow tax system with fewer allowable write-offs.
  • How to Take Advantage: Before making large purchases like a U.S.-assembled vehicle for the interest deduction, run a tax projection to see if the AMT will "claw back" those savings.  High-income earners should consult with their tax advisor to understand how the AMT might affect their specific filing status. 

 

Trump Accounts for Children

  • The Change: A new tax-advantaged savings vehicle called "Trump Accounts" launches on July 4, 2026.  For children born between 2025 and 2028, the federal government will provide a one-time $1,000 seed contribution.  Parents and others can contribute up to $5,000 annually, and employers can contribute up to $2,500 for an employee’s child.  However, the yearly contribution total cannot exceed $5,000.
  • How to Take Advantage: Once the program opens in mid-2026, you can establish an account for eligible children.  Funds must be invested in U.S. stock index funds, and while contributions are after-tax, earnings grow tax-deferred until the child reaches age 18.
  • At age 18: At age 18, The child becomes the sole owner and takes full control from the parent or guardian custodian.  At this point, the account essentially becomes a Traditional IRA, subject to the normal IRA rules.

 

The One Big Beautiful Bill Act represents a paradigm shift in the American tax landscape, moving away from temporary patches toward a framework of long-term stability.  By making cornerstones like the QBI deduction and elevated estate exemptions permanent, the Act empowers individuals and business owners to move beyond reactive year-end scrambling and toward proactive, multi-generational wealth management.  From the immediate relief of untaxed overtime and senior bonuses to the future-focused "Trump Accounts," these provisions offer a rare convergence of populist relief and structural reform.  For the informed taxpayer, 2026 marks the beginning of an era where strategic participation in these new incentives can significantly lower one’s effective tax rate while fueling broader domestic economic growth.
