Two big changes in the new law affect high earners in high-tax states—and retirees living on fixed incomes.
As part of our ongoing look at the “One Big Beautiful Bill,” we’re diving into the updates to State and Local Tax (SALT) deductions and Social Security taxation—two issues that have long caused headaches for taxpayers across the income spectrum.
This post explains what’s changing, who benefits, and what to expect starting in tax year 2025.
SALT Deduction Cap Is Temporarily Expanded
If you live in a high-tax state like New York, California, or Connecticut, you’re likely familiar with the $10,000 cap on state and local tax deductions, known as the SALT cap.
Here’s what’s changing:
- Cap raised from $10,000 to $40,000 per household in 2025
- Increases 1% annually through 2029 (e.g., $40,400 in 2026)
- Phases out for incomes over $500,000, with a return to the $10,000 cap for high earners
- Cap reverts back to $10,000 in 2030 and beyond
Middle- and upper-middle-income households in high-tax states will see meaningful federal tax relief—but only for a limited time.
New Senior Deduction Reduces Social Security Taxes
Under previous rules, many retirees—especially those with modest pensions or investment income—still had to pay taxes on part of their Social Security benefits.
The new law introduces a $6,000 annual deduction for seniors (65+) starting in 2025.
Key details:
- Applies to all income, including Social Security
- Phases out at $75k single / $150k joint MAGI
- Fully phased out at $175k / $250k
- Not available to those filing “Married Filing Separately”
- Requires a valid Social Security number for work
Impact:
- Roughly 88–90% of retirees will now pay zero federal tax on their Social Security income
- Wealthier retirees may see limited or no benefit, as the deduction is phased out at higher incomes
This isn’t a total repeal of Social Security taxation—but for most seniors, the result is nearly the same.
In addition, the standard deduction is increasing for married taxpayers by $2300, and for single $1150. For those over age 65, in addition to the new $6000 deduction, the previous additional deduction has increased to, addition $3200 to the standard deduction for married, and $2000 for single.
- This means for 2025, a single senior filer can deduct up to approximately $23,750 in total standard deductions (base standard deduction of $15,750 + existing extra $2,000 for seniors + new $6,000 senior bonus). For married couples both over 65 filing jointly, the total can reach about $46,700. Remember the $6000 senior bonus is phase out at higher incomes.
These provisions reflect a dual focus:
- Easing the burden on working families and retirees
- Temporarily helping residents of high-tax states who’ve been hit hard by SALT limitations
For many households, these changes could mean thousands of dollars in savings between 2025 and 2029—making now a good time to revisit your tax planning strategies. Perhaps this gives you 5 years to do some Roth conversions!
