Weekly OBBBA Spotlight, Week 1: Permanent Lower Tax Rates & Enhanced Standard Deduction for Individuals

Welcome to our first entry in the Weekly OBBBA Spotlight! In this series, Seiberling & Company will break down the most important changes from the One Big, Beautiful Bill Act (OBBBA)—the landmark tax reform signed into law on July 4, 2025—so you can make informed decisions for your 2025 tax year and beyond.

We begin with perhaps the most impactful provision for individual taxpayers: the permanent extension of lower tax rates and a larger standard deduction.

What Changed with OBBBA for Individuals?

1. Permanent Lower Individual Tax Rates

For years, the reduced tax rates and expanded brackets from the 2017 Tax Cuts and Jobs Act (TCJA) were set to expire after 2025. OBBBA has now made these favorable rates and brackets permanent. Here’s what that means for you:

• No “snap back” to pre-2018 higher rates. The lower tax rates introduced by TCJA are here to stay, eliminating the uncertainty about future rate hikes.

• Expanded income brackets mean more of your income is taxed at lower rates than under pre-TCJA law.

• Marriage penalty relief for joint filers is preserved (except at the very highest bracket), protecting married couples from higher tax bills compared to two single filers.

Practical impact: Most households will continue to benefit from lower federal income tax rates, simplifying year-to-year planning and potentially reducing withholding or estimated tax payments.

2. Increased & Inflation-Indexed Standard Deduction

OBBBA also permanently increases the standard deduction, which now serves as the default deduction for most taxpayers. Key features:

• Higher deduction amounts: The standard deduction is raised above 2025 TCJA levels and will be indexed for inflation from a new base year, further increasing its value over time.

• Simplified filing: With miscellaneous itemized deductions still suspended (except for educator expenses), even more taxpayers will benefit from the simplicity and value of the standard deduction.

Why this matters: The higher standard deduction means fewer taxpayers will need to itemize, and most will see a reduction in taxable income right off the top.

Planning Tips for 2025 and Beyond

• Withholdings and Estimates: With these changes now permanent, it’s a good time to review your Form W-4 or quarterly estimated payments to make sure you’re not over- or under-paying.

• Itemizing vs. Standard Deduction: With the new standard deduction and the suspension of most miscellaneous itemized deductions, review whether itemizing still makes sense for your situation.

• Life Events: Marriage, home purchase, or changes in family size may affect your tax bracket and deduction strategy—consider a tax check-up if you’ve experienced a major life change.

What’s Next?

Next week, we’ll highlight enhancements to the Child Tax Credit and Other Dependent Credit—two provisions that can significantly reduce your tax bill if you have children or other dependents.
