Can I deduct sales tax on a car purchase?

Updated May 20, 2026 by Chris Rubino, EA

Purchasing a vehicle is a major milestone – but it also can come with a hefty sales tax bill. So, when tax season rolls around, many taxpayers wonder if that bill can be deducted from their federal return. 

The answer, unfortunately, is not always straightforward. It depends on how you choose to deduct your state and local taxes.

 

Requirements for Deductibility

Generally, the following conditions must all be met.
 

• Personal Use: The vehicle must be for personal use.
• You Itemize your Deductions: You must file Schedule A (Form 1040) rather than taking the Standard Deduction. (If your itemized deductions for the 2026 tax year do not exceed $15,750 for a single filer, or $31,500 married filing jointly, the standard deduction will probably be your best bet. If you are unsure whether it’s better to itemize versus taking the standard deduction, click here.)
• The "Sales vs. Income" Election: You must choose to deduct General Sales Taxes instead of State and Local Income Taxes. You cannot deduct both. 
  • In layperson’s terms, you have a choice for your state and local tax deduction. You can deduct the income tax you paid to state and local areas, or you can deduct the sales tax you paid in the tax year. However, it is rare that sales tax is better, unless you live in a state with no income tax.
• The Taxpayer Paid the Tax: You must be the one legally obligated to pay the tax, and you must have actually paid it during the tax year.

What Type of Vehicles Qualify? 

The IRS defines "motor vehicles" broadly for this deduction. You can include sales tax paid on:
 

• Cars, SUVs, Trucks, and Vans
• Motorcycles
• Motor homes / RVs
• Off-road vehicles
• Boats and Airplanes: These also qualify under the same rules as motor vehicles.

The "General Sales Tax" Rule

A common point of confusion is how much of the tax is actually deductible. The IRS stipulates that the deductible amount cannot exceed the general sales tax rate.

If your locality assesses a "luxury tax" or an additional vehicle-specific tax that is higher than the rate for general items (like food or clothing), only the portion equal to the general rate is deductible.

Example:

• State General Sales Tax: 7%
• Local Vehicle Surcharge: 3%
• Total Paid: 10%
• Deductible Amount: You may only deduct the 7% portion. The additional 3% is not deductible.

If you are unsure what these amounts are for your specific locality, we recommend contacting a local tax professional for guidance.

 

The "General Sales Tax" Calculation

You can deduct the actual sales tax you’ve paid all year (this requires that you keep ALL of your receipts and add the total sales tax paid at the end of the year), or you can use the IRS Optional Sales Tax Tables found here. If you use the IRS tables, you can add the sales tax paid on large purchases, such as a new or used vehicle.

 

Limitations

Since the 2018 tax year, state and local tax deductions have been subject to the SALT (State and Local Taxes) Cap. This cap was recently, and temporarily, increased by the One Big Beautiful Bill (OBBBA):
 

• The Limit: The total deduction for state and local taxes (including property taxes and either sales or income taxes) for any filing status besides married filing separately is limited to $40,000. (It is $20,000 if you are married filing separately). So, if your property taxes and other state and local taxes already reach $40,000, adding the sales tax from a $50,000 truck will provide zero additional federal tax benefit.

The "Refund" Advantage

Even if the deduction amount is similar, there is a strategic reason to choose Sales Tax over Income Tax. If you deduct State Income Tax, any refund you receive from the state next year may be considered taxable income. If you choose the Sales Tax deduction, your state refund is generally not taxable on next year’s federal return.

 

Conclusion

We understand that navigating the different tax laws, limitations, and numbers can be confusing. If you have specific questions or need help with your return, we strongly recommend contacting a local tax professional for assistance.
