What a financed car actually costs out the door in North Carolina — the sales tax this state really charges, whether it credits your trade-in, and what the payment does to what you can borrow for a house.
Trading a car in here reduces the amount sales tax is charged on, so you are taxed on the price less your trade-in allowance. That is the common rule, but it is not universal — a handful of states tax the full sticker price regardless, and the calculator below applies whichever rule is actually North Carolina’s.
North Carolina charges no sales tax on a vehicle purchase. It charges a one-time 3% Highway Use Tax when a certificate of title is issued, with no local add-on. Caps: $250 where the vehicle has been titled to the same owner in another state for at least 90 days beforehand, and $2,000 for a Class A or B commercial vehicle or a recreational vehicle. LEASES are not taxed up front on total value — they fall under the Alternate Highway Use Tax on the gross receipts of a 'limited possession commitment', at 3% for a long-term lease, 5% for a vehicle subscription and 8% for a short-term rental, i.e. a payment-stream method. Separately, NC levies a recurring annual vehicle property tax collected with registration renewal under 'Tag & Tax Together'.
Money factor, residual, and the payment — taxed by your state's actual method, since some states tax a lease's full value upfront instead of each payment.
Which dealer offer actually costs less over the life of the loan, and the rate at which they tie.
Income, savings, and debts in — max home price and qualification signal out.
A dealer offers 0% financing or $3,000 cash back. On a $38,000 car over 60 months the two cost exactly the same at 3.70% — and above that, the 0% wins by thousands.
Co-signing a $683-a-month car loan cuts the house payment you can qualify for by $683 — dollar for dollar. And if it defaults, you owe the whole balance, not half.
One number, in writing, itemised — and the scripts that get it. Every line a dealer can add, which of them are negotiable, and what your own state's tax rules do to the total.
One number, itemised, with the taxable amount working your state's trade-in rule live rather than leaving it to you to remember: four states with a sales tax credit nothing against a trade-in, and Ohio credits it against a new vehicle only. Checks a documentation fee against the nine statutory caps this site has confirmed, and is explicit that the other 41 states are unresearched rather than uncapped. Prices the F&I office as the optional extra it is, and adds the trade-in payoff back into the amount financed — because negative equity does not disappear when you trade the car, it moves into the new loan and accrues interest.
