Itemized deduction limitation: OBBBA made the TCJA repeal of the Pease limitation permanent, but it introduced a new overall limit on itemized deductions applicable to those in the top 37% tax bracket for tax year 2026 and beyond. The new limit cuts the tax benefit from itemized deductions by 2% (effectively capping the tax benefit from itemized deductions at 35%).
Planning: High-net-worth taxpayers expecting to be subject to this limitation in 2026 should consider accelerating itemized deductions, such as charitable contributions, into 2025.
Several new charitable contribution provisions
Charitable contribution floor: OBBBA introduced a new limit on charitable contributions that applies to all itemizing taxpayers. For tax years after 2025, charitable deductions are subject to a new floor equal to 0.5% of adjusted gross income (AGI). Only charitable deductions in excess of the 0.5% floor are deductible. For example, a taxpayer with $200,000 of AGI will be unable to deduct the first $1,000 of charitable contributions.
Planning: Especially in context of the overall itemized deduction limitation, this provision further reduces the tax benefit from charitable contributions. Taxpayers should consider accelerating charitable deductions into 2025. Additionally, if a taxpayer has an excess charitable carryover, the amount limited by the charitable floor also carries over to the subsequent year. As a result, taxpayers close to generating an excess charitable carryover should consider contributing just enough to put them into an excess position in order to preserve the floor limited amount for future years.
60% AGI limitation: OBBBA made the 60% AGI limitation for cash contributions to public charities permanent.
Charitable deduction for non-itemizers: Starting in 2026, taxpayers who do not itemize can deduct up to $1,000 ($2,000 for joint returns) of cash contributions made to public charities each year. The following gifts are not eligible: 1) noncash gifts (such as clothing or household goods), 2) gifts to section 509(a)(3) supporting organizations and 3) gifts to donor advised funds (DAFs). Additionally, charitable carryovers from prior years are not eligible to be deducted under this non-itemizing provision. This new below-the-line deduction for non-itemizers is permanent.

State and local tax deductions: TCJA limitations on state and local tax deductions remain, but OBBBA increases the deduction to $20,000 (MFS) and $40,000 (all other filers). The deduction phases down for taxpayers with modified AGIs (MAGIs) exceeding $250,000 (MFS) and $500,000 (all other filers) but not below $5,000 (MFS) or $10,000 (all other filers). Starting in 2026, the deduction cap and phase-down threshold will increase 1% annually through 2029 before reverting back to the $10,000 TCJA cap.
Planning: Consider whether a taxpayer would benefit from prepayment of state and local tax payments before year-end 2025. Taxpayers in the phaseout range ($500,000 to $600,000 for most filers) will see an increase in their effective tax rate of 30%, due to the loss of their SALT deduction. Consider whether managing a taxpayer’s income to keep below this punitive phaseout makes sense.
Pass through entity tax (PTET): The final legislation includes no changes to PTET workarounds. Subject to state availability and conformity, business owners can continue to avail themselves of PTET regimes, which allows some business owners to avoid application of the SALT cap on state income taxes paid directly by their business entity.
Enhanced senior citizen deduction: Taxpayers who have reached age 65 in tax years 2025 through 2028 receive an additional $6,000 “temporary senior deduction,” which is phased out at MAGIs over $150,000 (MFJ) and $75,000 (other filers). The amount is allowed for itemizers and non-itemizers and is not indexed for inflation.
Consider: Social security benefits remain taxable, but this provision was introduced as a partial fulfillment of President Trump’s campaign pledge to eliminate taxes on social security. This deduction is also on top of a senior’s standard deduction and the additional standard deduction available to taxpayers over the age of 65.
Qualified small business stock: OBBBA increases the per-issuer gain exclusion cap to $15 million for stock acquired and the gross assets ceiling to $75 million for stock issued after the July 4, 2025, enactment date. Starting in 2027, these amounts will be adjusted for inflation. OBBBA also introduced a graduated exclusion holding period with 50% exclusion after three years, 75% after four years, and 100% after five or more years.
Planning: Carefully consider choice of business entity for startups.
Tax credits for contributions to scholarship granting organizations: An annual tax credit of $1,700 is available starting in tax year 2027 for contributions of cash to scholarship granting organizations (SGOs). SGOs are tax-exempt organizations for which substantially all activities provide scholarships for qualified elementary and secondary expenses of eligible students. No charitable deduction is allowed for amounts claimed as a credit.
529 plans: OBBBA expanded eligible K-12 education expenses to include curriculum materials, books, online materials, tutoring, standardized testing fees, higher education dual enrollment expenses, and educational therapies for students with disabilities. Additionally, the annual amount of elementary and secondary expenses eligible to be paid from a 529 plan increases to $20,000 per beneficiary starting in 2026. Certain qualified postsecondary credentialling expenses (e.g., CPA exam fees or licensing fees) are also added to the list of eligible 529 expenses.
Note: The new categories of eligible expenses took effect upon enactment on July 4, 2025, so they could yield a 2025 benefit.
Trump child accounts: A new tax-favored account similar to a nondeductible IRA is created for U.S. citizens under age 18. The federal government will contribute $1,000 to such account for every U.S. citizen born during 2025 through 2028. Additionally, contributions of up to $5,000 (inflation adjusted) per year can be made from birth through age 17, with no distributions allowed until age 18. Distributions are subject to the rules applicable to traditional IRAs. Investment options are limited to U.S. equity index investments with expense ratios not exceeding 0.1%. The law also provides for an employer exclusion for contributions up to $2,500 (inflation adjusted). Distributions can be taken under the normal traditional IRA rules with limited pre-59 ½ distributions allowed for qualified college expenses and first-time home purchases. Contributions are returned tax-free, but income would be taxed at ordinary rates with penalties for nonqualified distributions. Under OBBBA, the earliest these accounts can be available to accept contributions is July 4, 2026.
Planning: Trump accounts give families the opportunity to give their children a substantial head start on retirement saving. However, for many parents, 529 plans remain a superior choice among tax-favored savings vehicles.
Deductible car loan interest: For tax years 2025 through 2028, OBBBA allows a deduction for up to $10,000 of new car loan interest on U.S. assembled vehicles. Only new car loans taken out or refinanced (if it doesn’t add to the balance of the original loan) in 2025 through 2028 are eligible. The deduction phases out for MAGIs exceeding $200,000 (MFJ) and $100,000 (other filers) (fully eliminated at $250,000 (MFJ) and $150,000 (other filers)). This deduction is available for non-itemizers.
Tips deduction: OBBBA establishes a new below-the-line deduction through 2028 for qualified tip income. Taxpayers may deduct up to $25,000 of qualified tip income, subject to a phaseout for individuals whose MAGI exceeds $150,000 ($300,000 for joint filers). Tips must be voluntary, nonnegotiated and paid by the patron and can be paid by cash or charged. Taxpayers in occupations that customarily and regularly receive tips prior to 2025 are eligible for the tip exclusion. On Sept. 22, 2025, the IRS issued proposed regulations that include a list of eligible occupations. Federal employment taxes and possibly state and local income taxes still apply to excluded tip income.
Overtime deduction: OBBBA establishes a new below-the-line deduction through 2028 for qualified overtime (OT) income. Taxpayers may deduct up to $12,500 of qualified overtime income ($25,000 for joint filers). There is a phase-out component for individuals whose MAGI exceeds $150,000 ($300,000 for joint filers). For overtime deductions, employees must receive OT pay as defined by the Fair Labor Standards Act (i.e., pay for hours worked beyond 40 in a regular work week). Note that the deduction only applies to the amount paid in excess of their regular hourly rate.
