You will probably also have to pay the county use tax when you register. See the registration fees and estimated taxes for information on county use taxes.
OK thanks. I'd also want to find out  pay the county use tax when you register. I want to know how to estimate the fees for registering trailers and boats.
the estimation for registering a trailer and a boat are different. You can't use the online service to estimate them. You can get info for registering one or the other.
there is more about  sales tax payment or sales tax exemption, or purchase price. Should I accept the invoice?
