where do I include car taxes

You can deduct car registration fees as itemized deduction on your federal tax return if they are calculated based on a percentage of the value of the vehicle. You will see the entry in the Deductions and Credits section, then Cars and Other Things you Own, then Car Registration Fees. You must be able to benefit from itemizing your deductions on your federal tax return for the deduction to benefit you. The base standard deduction for a single filer in 2024 is $14,600 and twice that amount for married filing joint. You need to choose the standard deduction or the itemized deductions method.
