In July, Congress passed what may go down as the most consequential tax legislation in a generation: the One Big Beautiful Bill (OBBB). Don’t let the name fool you. Behind it lies a complex set of tax, estate, education, and retirement changes that demand your attention. Watch our webinar below as we discuss the major components of the bill that may impact you. 👇
Many provisions from the 2017 Tax Cuts and Jobs Act were set to expire in 2025. The OBBB not only extends those, but it also layers in permanent and wide-ranging updates that affect everything from charitable giving thresholds to estate tax exemptions.
Here are the key strategic shifts we’re watching and how they could affect your financial plan.
Breaking Down the One Big Beautiful Bill Act (OBBB)
Key Tax Provisions
Under the OBBB, the State and Local Tax (SALT) deduction cap jumps from $10,000 to $40,000 in 2025. But there’s a catch: the benefit phases out for AGIs between $500,000 and $600,000. For high earners, this creates a narrow planning window where tax-advantaged vehicles such as 401(k), SEP IRA, HSAs, and tax-loss harvesting, can pull AGI below that threshold and maximize deductions.
Standard Deduction: Slight upticks in the standard deduction benefit most filers.
Mortgage Interest Deduction remains unchanged in the OBBB; however, a novel $10,000 Auto Loan Interest Deduction for U.S.-assembled vehicles, available as a non-itemized deduction, introduces a rare new twist, with income limits attached in our downloadable guide below.
Estate Planning Just Got Easier
Perhaps the most investor-friendly change in OBBB: the federal Estate Tax Exemption is now permanently set at $15 million per person (or $30 million per couple), indexed for inflation. This alleviates looming sunset concerns and gives ultra-high-net-worth families greater freedom to transfer wealth strategically with less urgency and fewer constraints.
Charitable Giving: Time Your Moves
Starting in 2026, non-itemizers can deduct up to $2,000 in cash donations to public charities. Meanwhile, high earners face new hurdles: a 0.5% AGI floor and a cap on charitable deductions reduced from 37% to 35% of AGI.
Translation? If you’re planning a large charitable gift, 2025 is your window to optimize deductibility before the new OBBB restrictions hit. Consider front-loading contributions, leveraging donor-advised funds, and reviewing AGI impact across your broader tax picture.
New Tools for Generational Wealth Planning
“Trump accounts” are a new child-focused retirement vehicle that offer $5,000 annual contributions (plus $2,500 from employers), tax-deferred growth, and early seed government funding of $1,000 for children born between 2025 and 2028. Withdrawals are restricted until age 18, with IRA-style penalties thereafter.
Used smartly, these could become foundational components in legacy planning, particularly for families aiming to pass down tax-advantaged capital across generations.
The OBBB also created 529 Plan flexibility by expanding use-cases to vocational programs, and doubled annual K-12 withdrawal limits to accommodate a broader range of education goals.
Student Loan Overhaul = Financial Aid Strategy Rethink
Starting in 2026, the new Repayment Assistance Program (RAP) replaces SAVE, adjusting payments based on a fixed percentage of income (up to 10%). Grad PLUS loans are gone; Parent PLUS loans are now capped.
If you’re planning for college costs—or helping fund education for children or grandchildren—this change may alter how you balance 529 plan contributions, income timing, and debt strategy.
The Senior Deduction
While taxes on Social Security benefits will remain in place, there is a new senior deduction. From 2025–2028, the senior deduction offers $12,000 for joint filers over 65, regardless of itemizing—but it phases out above $150,000 AGI. This gives retirees a short window for smart income planning, including Roth conversions and Social Security timing, to stay under the phase-out threshold.

Final Thought: Details Matter More Than Ever
The One Big Beautiful Bill brings significant opportunity, but also complexity. With layered phase-outs, new deduction rules, and strategic timing considerations, high-income earners and retirees alike must take a proactive, customized approach.
If your financial plan hasn’t been revisited since the bill passed, it may be time for forward-looking, customized planning to capitalize on evolving opportunities and safeguard against phaseouts and legislative sunset risks.
