The only car fees, they’re deductible are taxes that are based on the value of the car. For example, if registration is a flat fee of $80 per vehicle, nothing is deductible. The first time you register your car in your state, you might be required to pay flat registration fee per vehicle plus an additional fee based on the value of the car. That is a deductible tax. Or, you might pay an annual tax based on the value of the car. In my state, I pay a personal property tax for my car, which consist of a small flat fee, plus a large tax based on the value which goes up or down as the bluebook value changes. The flat fee is not deductible, but the tax based on the value is deductible.
not all vehicle registration fees are counted as deductible. Taxes, depends on your state, and what you actually pay. There may be a blue link on the TurboTax page that says “what does this mean”? Or “show me more details” which will explain things in more detail.
separately, you may pay sales tax when you purchase a new vehicle, or one that is new to you.
when you itemize your deductions, you can deduct sales tax or state income tax, but not both. Then, if you pay a separate tax based on the value of the car, that may be added to your tax deductions, whether or not you deduct sales tax or income tax.
