What changed: Tax brackets and the top rates
The IRS applied inflation adjustments to the income thresholds that determine each tax bracket for 2026. The seven rates remain the same: 10%, 12%, 22%, 24%, 32%, 35% and 37% (reporting: Fox Business; CBS News).
For example, the 37% top rate now begins at $640,600 for single filers and $768,700 for married couples filing jointly. The 35% bracket starts at $256,225 for single filers and $512,450 for married filing jointly. These adjustments are intended to reduce tax “bracket creep” caused by inflation.
“The rates themselves are not new; the IRS moved the thresholds higher to reflect changes in prices and wages.”
Standard deduction increase and who benefits
One of the most practical changes is the increased standard deduction for 2026: $16,100 for single filers and $32,200 for married couples filing jointly. The One Big Beautiful Bill Act had already raised amounts for 2025; the IRS adjusted them further for 2026 (see Fox Business; H&R Block).
Practical effect: More taxpayers may prefer the standard deduction over itemizing. Those who previously itemized for SALT, mortgage interest or charitable giving should recalculate with the new amounts.
Other notable 2026 changes
- Estate tax exclusion: rises to $15 million for decedents who die in 2026 (up from $13.99 million in 2025) — Fox Business.
- Adoption credit: increases to $17,670 in 2026, including a $5,120 refundable portion — Fox Business.
- Alternative Minimum Tax (AMT): individual AMT exemption $90,100 (phasing out at $500,000); married couples exemption $140,200 (phasing out at $1 million) — Fox Business.
- Employer-provided childcare credit: cap raised from $150,000 to $500,000 for most businesses, and to $600,000 for eligible small employers — Fox Business.
- Senior tax relief: a temporary deduction up to $6,000 is available through 2028 for taxpayers 65+ with AGI limits ($75,000 single; $150,000 joint) — (see CBS News; H&R Block).
How the One Big Beautiful Bill Act shaped these numbers
The One Big Beautiful Bill Act (OBBBA) made several structural changes: it kept the seven TCJA rates in place, preserved a larger standard deduction, and adjusted personal exemption treatment with limited senior exceptions.

Implications for The Imperial Valley, California

Political consequences, social effects and cultural relevance
