Homeowners and taxpayers who need to understand the specific SALT cap amounts for tax planning
The specific SALT deduction caps for 2026
The new SALT deduction caps for 2026 vary by filing status under the One Big Beautiful Bill Act:
These caps apply to the total of your state income taxes, local income taxes, sales taxes (if elected instead of income taxes), and property taxes. According to IRS Publication 17, you can choose between deducting state income taxes or state sales taxes, but not both.
How to calculate your SALT deduction
To determine your SALT deduction, add up:
1. State income tax paid (from W-2 withholding, estimated payments, or prior year refund applied)
2. Local income tax paid (city, county, school district taxes)
3. Real estate property taxes (on primary residence, vacation homes, rental properties for personal use)
4. Personal property taxes (vehicle registration fees that are based on value)
Then apply your filing status cap.

Taxpayers who recently purchased vehicles and want to understand how vehicle taxes fit into SALT deductions
How vehicle taxes count toward your SALT deduction cap
For car buyers, understanding what vehicle-related taxes count toward the SALT deduction is crucial, especially with the higher 2026 caps providing more room for these deductions.
Vehicle taxes that count toward SALT
Personal property taxes on vehicles count toward your SALT deduction if they meet these criteria:
For example, if you bought a $35,000 car in Virginia and pay $850 in annual personal property tax based on the assessed value, this counts toward your SALT deduction.
What doesn't count
State-by-state vehicle tax impact
Some states have significant vehicle personal property taxes:
Example: New car purchase impact
Tom (single filer) lives in Virginia and bought a new $40,000 truck in 2026:
Without the vehicle taxes, his SALT deduction would be $12,700, so the vehicle personal property taxes add $1,500 to his deduction.
Planning tip for car buyers
If you're considering a major vehicle purchase and live in a state with personal property tax on vehicles, factor this into your SALT deduction planning. The higher 2026 caps provide more room to benefit from these deductions.
Key takeaway: Vehicle personal property taxes count toward SALT deductions if they're value-based annual taxes, and the higher 2026 caps provide more room to benefit from these deductions in states like Virginia and Connecticut.
Key Takeaway: Vehicle personal property taxes count toward SALT deductions if they're value-based annual taxes, adding potential deduction value under the higher 2026 caps.
