Title and lien fees are never deductible. Sales tax is deductible if you itemize your deductions and if you choose to deduct sales tax instead of state income tax. Registration fees may be deductible if a part of the registration fee is based on the value of the car. Any part of the registration fee that is simply to get a license plate or to get permission to drive on state roads is not deductible, but if there is a value tax included in the registration fee, the value tax may be deductible.
