Just a quick update about some recent tax law changes, some will likely impact you.
President Trump signed the One Big Beautiful Bill Act (OBBBA) on July 4. The Act primarily extends and replaces the expiring 2017 Tax Cuts and Jobs Act (TCJA).
Among all the changes, one really stood out: a major increase to the cap on State and Local Tax (SALT) deductions.
Starting in 2025, the SALT deduction cap will increase from $10,000 to $40,000 for households earning under $500,000. For higher incomes, this cap gradually gets smaller.
(Note): The higher cap, which is effective until the end of 2029, will revert to $10,000 starting in 2030.1
SALT Deduction “Savings” Example
The higher SALT deduction means some taxpayers may save more money by itemizing their taxes this year versus taking the standard deduction.
Here’s an example…
Assumptions:
- Married Filing Jointly
- Adjusted Gross Income (AGI): $300,000
- SALT Paid: $35,000 (including property and state income tax)
- Other Itemized Deductions: $7,000 (e.g., charitable giving and modest or no mortgage interest, common for many pre-retirees and retirees with paid-down loans)

This example shows how the increased SALT deduction can shift a married couple’s advantage, enabling them to itemize for an extra $10,500 in deductions, leading to an estimated $2,520 in tax savings compared to the prior 2024 standard deduction rules.
Temporary Deductions
The Act also introduces several new temporary deductions for 2025-2028, including:
- A $6,000 deduction for single filers ($12,000 for joint filers) for those aged 65+.
- Up to $25,000 for tips; and overtime wages ($12,500 for single filers, $25,000 joint filers). Note, payroll taxes still apply.
- Up to $10,000 for qualifying auto loan interest on new, U.S.-assembled vehicles.
Keep in mind, the above deductions are subject to income phase-outs and other restrictions.2
Other Key OBBBA Highlights:
Permanent Tax Cuts: Many TCJA provisions are now permanent, including the existing individual income tax brackets (10%, 12%, 22%, 24%, 32%, 35% and 37%), and the increased standard deduction, now $15,750 for single filers, $23,625 for heads of household and $31,500 for joint filers, for 2025.
Child Tax Credit: The Child Tax Credit is permanently increased to $2,200 beginning in 2025, and will be indexed for inflation beginning in 2026.3
