Quick Answer
Yes, you can deduct state and local sales tax on major purchases if you itemize and choose the sales tax deduction over state income tax. For 2026, this is particularly valuable for major purchases like vehicles ($2,500+ in sales tax) or home improvements in states with no income tax.

How the state and local sales tax deduction works
Yes, you absolutely can deduct state and local sales tax on major purchases — and this often-overlooked strategy can save you hundreds or even thousands in taxes. Under IRC Section 164(b)(5), you can choose to deduct either state income tax OR state and local sales tax on Schedule A, Line 5b.
The key is that you must choose one or the other for the entire year. You cannot mix and match or take both.
When the sales tax deduction makes sense
The sales tax deduction is typically better when:
Example: $35,000 car purchase in Texas
Let's say you live in Texas (no state income tax) and bought a $35,000 car in 2026:
Using the IRS sales tax tables for Texas, a married couple earning $100,000 would have a base sales tax deduction of approximately $1,234. Add the $2,887.50 from the car purchase, and your total sales tax deduction becomes $4,121.50.
If you're in the 22% tax bracket, this saves you $906.73 in federal taxes.
Comparison: Sales tax vs. income tax deduction
How to calculate your sales tax deduction
You have two options:
Option 1: IRS Tables Method
Option 2: Actual Sales Tax Method
Major purchases that qualify
Note: The purchase must be for personal use. Business purchases are deducted elsewhere.
What you should do
1. Gather your records: Collect receipts for all major purchases showing sales tax paid
2. Calculate both options: Compare your state income tax vs. potential sales tax deduction
3. Use our return scanner: Upload your tax documents to identify which option saves more
4. Don't forget local taxes: Many overlooked local sales taxes can add 1-3% to your deduction
Key takeaway: The sales tax deduction can be worth $500-$2,000+ in tax savings for those with major purchases, especially in no-income-tax states. Most tax software doesn't automatically optimize this choice.
Key Takeaway: Choosing sales tax over income tax deduction can save $500-$2,000+ annually, especially with major purchases like vehicles in no-income-tax states.
When to choose sales tax vs. income tax deduction
| State Type | Income Tax Paid | Sales Tax (with major purchase) | Better Choice |
|---|---|---|---|
| No income tax (TX, FL) | $0 | $4,121 | Sales tax |
| Low income tax (TN, WA) | $500 | $3,800 | Sales tax |
| Moderate income tax (GA, NC) | $2,800 | $3,200 | Sales tax |
| High income tax (CA, NY) | $8,500 | $4,000 | Income tax |

Strategic considerations for high earners
As a high earner, the sales tax vs. income tax decision becomes more complex due to the $10,000 SALT (State and Local Tax) cap under IRC Section 164(b)(6). This cap applies to the TOTAL of your state income tax, property tax, AND sales tax combined.
The SALT cap strategy
If you're already hitting the $10,000 SALT cap through property taxes and state income tax, adding sales tax won't provide additional benefit. However, if your property taxes are lower, the sales tax route might maximize your deduction.
Example: High earner in Florida
Vs. High earner in New York:
The Florida resident gets the same $10,000 deduction despite paying less tax overall.
When high earners should consider sales tax deduction
1. Luxury purchases in no-income-tax states: Boats, aircraft, expensive vehicles
2. Property taxes under $10,000: Room to add sales tax to reach the cap
3. Multiple-state complications: When state income allocation is complex
What you should do
Work with a tax professional to model both scenarios, especially if you're subject to alternative minimum tax (AMT) or have complex state tax situations.
Key Takeaway: High earners must consider the $10,000 SALT cap when choosing between income tax and sales tax deductions.

Retirees on fixed income who may have made major purchases and want to minimize their tax burden
Why retirees often benefit from the sales tax deduction
Retirees frequently benefit more from the sales tax deduction because their state income tax is often lower due to:
Common retiree purchases that qualify
RV or travel trailer: Many retirees purchase recreational vehicles. A $85,000 Class A motorhome in Texas would generate approximately $5,312 in sales tax.
Downsizing purchases: New furniture, appliances, or home improvements when moving to a smaller home.
Vehicle purchases: Many retirees buy their "retirement car" — often a more expensive, comfortable vehicle they plan to keep long-term.
Example: Retired couple in Arizona
Savings in 12% tax bracket: ($5,125 - $800) × 12% = $519
What you should do
Review your state's treatment of retirement income and compare it to your sales tax from major purchases. Many retirees are surprised to find the sales tax deduction is significantly larger.
Key Takeaway: Retirees often have lower state income tax due to retirement income exemptions, making the sales tax deduction more valuable for major purchases.
