Yes, car registration fees may be partially deductible on your federal income taxes, but only under certain circumstances. A portion of the registration fee must be charged based on the vehicle's value -- as opposed to its size, age or other characteristics. If part of your registration is indeed deductible, you must itemize your deductions to claim it, rather than using the standard deduction.

Car fees go on the line for "personal property taxes." Note that your state might not specifically refer to the fee as a personal property tax. Nevertheless, if the fee is value-based and assessed on a yearly basis, the IRS considers it a personal property tax.
