Every year in NC. Based on the month the car is registered. Here they tie property tax into the renewal. So, if you don't pay your property taxes, you can't renew your license. The actual costs vary depending on the appraised value of the car, truck, RV, etc. For the DJ, the firt year we bought it, it was over $300 (U.S.) to get the car renewed, my truck, on the other hand, costs about $50 to renew because it's old and not worth much.
