Sales Tax Deduction Calculator

If you're itemizing deductions, you may be able to claim a deduction for state and local sales taxes you paid during the year. Our Sales Tax Deduction Calculator helps estimate your allowable deduction using your ZIP code, income information, and any qualifying large purchases.

Where to Find the Sales Tax Deduction Worksheet

To access the Sales Tax Deduction worksheet in the program, follow these steps:

1. Go to Federal.
2. Select Deductions.
3. Choose Select my forms.
4. Open Itemized Deductions.
5. Select Taxes You Paid.
6. Choose Sales Tax Deduction.
7. Click + Add sales tax you paid.

Enter Your ZIP Code Information

Enter the ZIP code where you lived and the number of days you lived there during the tax year.

If you moved during the year:

1. Enter your first ZIP code and the number of days you lived at that address.
2. Select Continue to save the information.
3. Add your next ZIP code and the number of days you lived there.

The calculator will use this information to estimate your deductible sales tax based on IRS guidelines.

Reporting Sales Tax on Large Purchases

The Sales tax paid on large purchases field is used for major purchases that typically involve significant sales tax, such as:

• Cars
• Motorcycles
• Boats
• Recreational vehicles (RVs)
• Other qualifying large-ticket items

Only enter the sales tax amount paid on the purchase, not the total purchase price.

The program adds this amount to the sales tax deduction calculated from your ZIP code and income information, which may increase your overall itemized deduction.

Important Reminder

You can generally choose to deduct either:

• State and local sales taxes, or
• State and local income taxes

You can't claim both on the same return. The software can help determine which option provides the greater tax benefit.

Need Your Sales Tax Amount?

If you purchased a vehicle or other large item during the year, check your purchase agreement, bill of sale, or registration documents. These records usually show the sales tax you paid and can help ensure your deduction is entered correctly.
