When you itemize deductions on your federal return, the IRS allows you to deduct either:
- đź’Ľ State & Local Income Taxes (SALT income tax), or
- đź›’ State & Local General Sales Taxes
👉 You cannot deduct both—you must choose the option that gives you the greater benefit.
Below is a clear breakdown to help you choose the right path.
🔍 What’s the Difference?
đź’Ľ 1. State & Local Income Tax Deduction
This deduction includes:
- State income tax withheld on your W‑2
- State estimated tax payments
- State tax paid when filing prior‑year returns
Best for:
- Taxpayers living in states with an income tax
- Individuals without major purchases that would generate large sales tax amounts
Most taxpayers living in these states benefit more from the income tax deduction.
đź›’ 2. State & Local Sales Tax Deduction
Instead of deducting state income tax, you may choose to deduct general sales tax you paid during the year.
The IRS allows you to use:
- 📊 Optional IRS Sales Tax Tables, based on income + location
- âž• Actual sales tax paid on major purchases, which you can add to the table amount
Best for:
- People living in states with no income tax
(e.g., Florida, Texas, Washington) - Taxpayers who made high‑dollar or frequent purchases, especially in high‑tax states
- Anyone who bought a major item like:
- đźš— Car, RV, or boat
- 🏡 Mobile home
- đź”§ Appliances or home renovation materials
This option can yield a much higher deduction depending on your spending.
đź§® SALT Deduction Cap (2025)
For tax year 2025, the total amount you can deduct for state and local taxes is capped at:
- $40,000 — Most filers
- $20,000 — Married Filing Separately
This cap applies to combined totals of:
- Income OR sales tax (whichever you choose)
- + Property taxes
