The NC vehicle registration fee is tax deductible. The NC vehicle property tax is deductible at the federal level but not at the state level. If it's not broken out on your paperwork, you can go to https://www.ncdot.gov/dmv/online/ and use their property tax estimator or back calculate the property tax portion by subtracting the vehicle registration fees applicable to your vehicle using the tables at https://www.ncdot.gov/dmv/fees/default.html?s=VF . Finally, you can call your county tax assessor as that is the ultimate authority for the vehicle property tax calculation and where one can appeal the assessment should you disagree with that office's vehicle valuation.
