Yes, you can deduct your car's tax on your federal income tax return, but only if you itemize your deductions using Schedule A and do not claim the state and local income tax deduction. You’re choosing to deduct state and local sales taxes instead. There's a key limitation: the deduction is capped based on the vehicle's purchase price. For 2023, you can only deduct sales tax paid on the first $49,500 of the purchase price, even if your car cost more. This is particularly beneficial for residents of states with no or low income tax but high sales tax rates.
The ability to take this deduction hinges on your tax situation. If the standard deduction provides a larger tax benefit than your total itemized deductions (which include mortgage interest, charitable contributions, and your chosen state/local tax deduction), then itemizing and claiming the sales tax deduction won't help you. This makes it less common for taxpayers after the standard deduction was significantly increased in 2018.
To claim this, you'll need to keep your bill of sale as proof of the sales tax amount paid. While you can use the IRS's sales tax calculator based on your state and income, deducting the actual tax paid on a major purchase like a car is often more advantageous. Remember, this is for federal taxes; state tax rules vary. If your adjusted gross income (AGI) is above a certain threshold, your total itemized deductions may be phased out. It’s always wise to consult with a tax professional to run the numbers for your specific circumstances.

Talk to your tax person. This isn't a simple yes or no. It depends entirely on whether you itemize your deductions, which most people don't do anymore because the standard deduction is so high. If you're self-employed and use the car for business, there's a whole different set of rules. Don't just assume you'll get this money back; the rules are pretty specific.

As a recent car buyer, I looked into this. You can only deduct it if you're itemizing your taxes, which means you're probably a homeowner with a mortgage. There's also a limit on how much of the car's price counts for the deduction. I used TurboTax, and it walked me through the questions to see if itemizing was better for me than taking the standard deduction. For my situation, it wasn't worth it.

The core rule is you have to choose: deduct your state income tax OR your state tax, not both. Since the sales tax on a car is a large amount, it might push you to choose the sales tax deduction if you live in a state like Texas with no income tax. But this only matters if your total itemized deductions exceed the standard deduction, which is about $13,850 for a single person. It's a math problem specific to you.

Keep your paperwork! This is crucial. You need the actual contract or invoice that clearly shows the sales tax amount you paid. The IRS will want to see that number if you're audited. Without that proof, you can't claim the deduction. Even if you use tax software, you'll be prompted to enter the exact amount from your documents. So, toss that buyer's order in with your other important tax documents for the year.
