Tax Reform 2025: What the OBBB Act Means for You and Your Family

July 17, 2025 | by Atherton & Associates, LLP

I. Introduction

The One Big Beautiful Bill Act (OBBB) ushers in fresh tax measures starting in 2025 that promise to influence the financial landscape for individuals and families across various income levels. Despite language that brands some changes as “permanent,” tax rules are always subject to future legislative adjustments. Consequently, it is critical to grasp these new provisions and plan proactively in order to make the most of the opportunities available right now.

With highlights like deductions for auto loan interest and temporary relief on state and local taxes (SALT), OBBB caters in large part to middle-income taxpayers. But individuals with higher incomes, retirees, and even small business owners will also be affected. Understanding how these provisions interact with your unique financial situation can help you adjust your strategies—from deciding whether to convert funds to a Roth IRA to optimizing charitable contributions—so that you minimize your overall tax burden.

II. Overview of the OBBB Act

One of the primary goals behind the OBBB Act is to alleviate strain on middle-income households facing rising debt and everyday expenses. As a result, provisions such as the above-the-line deduction for auto loan interest, overtime, and tip income stand out as hallmark features. At the same time, other measures address estate transfer planning and support for higher-income earners in key areas like capital gains recognition and entity-level SALT deductions. Nevertheless, no matter the bracket, it’s important to remember that opportunities presented here may be fleeting. Future Congresses can (and often do) revisit these “permanent” laws, making annual or even quarterly reviews of your financial plan essential.

It may seem daunting to keep track of every change. However, treating the new legislation as a window of opportunity can help you preserve more of your wealth through thoughtful planning. Whether you aim to limit your taxable income to qualify for favorable deductions or plan a robust estate strategy that accounts for a bigger exemption, these new laws provide reasons to re-examine your financial position now rather than later.

III. Key Provisions and Their Implications

1. Top Marginal Tax Rate Unchanged

   Under the OBBB Act, the highest marginal tax rate remains set at 37%. This continuity extends to capital gains rates as well, which stay at 0%, 15%, or 20%, depending on your overall taxable income. For those with significant income from investments, this means that strategies like carefully timing capital gains or performing Roth IRA conversions can continue without the worry that you might suddenly jump into a much higher bracket. Although some predicted a rate hike, the absence of such a change provides a measure of stability for the moment.

2. Elimination of Personal Exemptions but Addition of a Senior Deduction

   While personal exemptions are now permanently repealed, the Act introduces a new $6,000 deduction specifically for seniors. Although this deduction will help offset tax for older individuals, it does not automatically make all Social Security tax-free. Depending on your other taxable income—such as pensions or retirement account distributions—up to 85% of Social Security can still be taxed. Strategic moves, like staggering the timing of required minimum distributions (RMDs) or transferring some balances into Roth accounts, can help keep more of your Social Security benefits in your pocket.

3. Auto Loan Interest Deduction with Income Restrictions

   Middle-income earners could benefit from a new deduction that allows up to $10,000 of auto loan interest annually, so long as modified adjusted gross income (MAGI) stays under $100,000 for single filers or under $200,000 for joint filers. This limit phases out for those with higher income levels, making it less meaningful for wealthier taxpayers. However, individuals near the threshold might adjust their income through tactics such as deferring compensation, timing business deductions, or accelerating charitable giving.

4. Expanded Child Tax Credit

   Parents can expect a modest lift from the Child Tax Credit, which rises to $2,200 per child and will be indexed for inflation going forward. Families at higher income levels should note that the same $400,000 joint-filer phaseout remains in place. While not a dramatic increase, it can still provide some financial breathing room each year as child-related expenses mount.

5. Temporary Relief for SALT Deduction

   In 2025, the SALT deduction cap jumps from $10,000 to $40,000, offering a temporary but crucial respite for taxpayers in states with higher levies. This elevated cap is set to gradually revert to $10,000 by 2029. If you own a pass-through entity, the entity-level tax workaround remains one of the most powerful strategies to sidestep SALT limitations. However, watch for new deadlines. For example, California’s pass-through entity tax election is scheduled to expire at the end of 2025 unless lawmakers opt for an extension.

6. Charitable Contribution Deductions Capped at a 35% Benefit

   Under the new law, donors in the 37% tax bracket will be limited to receiving a 35% tax benefit on their charitable contributions. While this may reduce the dollar-for-dollar advantage, there are still ways to optimize your giving. Strategies like donating long-term appreciated stock, establishing a donor-advised fund, or even bunching several years’ worth of contributions can yield a stronger overall tax benefit—despite the new limitation.

7. Estate & Gift Tax Exemption Extended

   Beginning in 2026, the estate and gift tax exemption jumps to $15 million for an individual (or $30 million for a married couple), granting a larger buffer against federal estate taxes. Since it was previously set to drop to about half that amount, many families will enjoy a broader margin for wealth transfer. Legislative risk remains, though. As a result, forward-thinking estate planning is essential to lock in potential savings and maintain flexibility in the face of possible future changes.

8. 529 Plan Enhancements and Expanded Qualified Expenses

   In an ongoing effort to encourage education savings, the OBBB Act broadens how 529 plans may be used. More K–12 expenses (such as tutoring) and professional credentialing can now be financed from these accounts without losing tax benefits. Beginning in 2026, up to $20,000 per year may be withdrawn to pay for K–12 tuition. Front-loading 529 contributions can be especially advantageous, as larger deposits have more time to grow and benefit multiple generations.

9. New “Trump Accounts” for Children

   Children born between 2025 and 2028 may see a $1,000 initial federal contribution into a new kind of tax-deferred account—referred to by many as “Trump Accounts.” While these accounts function similarly to IRAs, the withdrawal rules and requirements remain somewhat unclear. Over time, they could provide comfortable savings for future goals, but the final guidance from the Department of the Treasury will be vital to clarifying how distributions should be managed.

10. Deduction for Overtime and Tip Income

    For workers who rely on tips or overtime for a substantial slice of their earnings, an above-the-line deduction of up to $25,000 on tips and $12,500 on overtime (capped at $25,000 if filing jointly) applies from 2025 through 2028. This valuable benefit phases out at higher MAGI levels, so those approaching the threshold may benefit from fine-tuning their income flows or deferring certain receipts to maintain eligibility.

“These new provisions are exciting, but the real key is synchronizing them with each family’s financial goals. It’s not just about tax-reduction strategies in isolation. It’s about ensuring your overall plan aligns with life events, from purchasing a home to passing on wealth,” says Jackie Howell, Tax Partner at Atherton & Associates LLP.
