OBBBA Highlights

Recent tax law changes under the One Big Beautiful Bill Act (OBBBA) create several planning opportunities for individuals and business owners, along with some important compliance watchpoints. Below is a high-level overview of four items that may be worth a closer look depending on your situation:

  • Higher SALT Cap for Itemized Deductions:
    • The long-standing $10,000 cap on the state and local tax (SALT) deduction has been temporarily expanded. For 2025, the SALT cap increases to $40,000 per return ($20,000 if married filing separately) and reverts to $10,000 starting in 2030.
    • A phase-out applies at higher income levels, so as modified AGI rises above specified thresholds ($250,000 for single filers/$500,000 for married filing jointly), the benefit of the higher cap is reduced—but never falls below the original $10,000.
    • Importantly, OBBBA does not change the popular state pass-through entity (PTE) tax election that many business owners utilize at the entity level.
  • Roth Catch-Up Contributions for 401(k) plans:
    • Traditionally, employees over the age of 50 have been able to make a catch-up contribution in addition to the annual contribution threshold.
    • For 2026, the catch-up contribution limits are $8,000 for those aged 50-59 and 64 +. For those aged 60 – 63 years old there is a special higher limit of $11,250.
    • Beginning in 2026, employees over age 50 with prior year Social Security wages exceeding $150,000 (indexed) are no longer allowed to make pre-tax catch-up contributions. The catch-up contributions must be treated as Roth contributions.
    • Please note that this rule only applies to catch-up contributions; normal 401(k) contributions within the annual threshold may still be treated as pre-tax.
    • It is the responsibility of the employer and plan sponsor to enforce this change but we felt it important to bring to your attention.
  • Deduction for Interest on American-Built Vehicle Loans:
    • OBBBA created a new above-the-line deduction for interest paid on certain auto loans. Qualifying taxpayers may be able to deduct part of the interest on a loan used to buy a new, American-built vehicle for primarily personal use, even if they do not itemize their deductions.
    • This provision applies to loans originated between 2025 and 2028 for new vehicles with final assembly in the United States.
    • However, the deduction is capped and phases out at higher income levels (MAGI of $100,000 for single and $200,000 for married filing jointly taxpayers), so higher-income households may see a reduced or no benefit.
    • Vehicle lenders will be issuing a Form 1098-VLI to help identify your eligible interest paid for the year.
    • If you are planning to finance a new vehicle in the next few years, the timing, where the vehicle is built, and your income level will all matter.
  • Trump Accounts:
    • Officially called Trump accounts, these new tax-favored savings accounts are geared toward benefiting children for years to come.
    • Eligible children are U.S. citizens born between 2025-2028 with a Social Security number.
    • Upon creation of the account, the account will receive a one-time $1,000 Federal “seed” contribution. This seed money is non-taxable for Federal and California.
    • Families and others can contribute annually up to a set dollar limit, with a separate smaller limit for employer contributions.
    • Contributions are not tax-deductible, but earnings and growth are tax-deferred.
    • Investments must be in low-fee U.S. equity index funds, and withdrawals are generally locked up until the child reaches 18 years old, at which point the account transitions into a traditional IRA.

Each taxpayer’s situation is unique, and additional facts may change the analysis. Please consult your DKC professional to discuss how these provisions apply to your specific tax circumstances.
