You pay no Maryland vessel excise tax, normally 5 percent, for one year on a boat you bring into Maryland when you move here on a permanent change of station. The boat has to stay registered in another state.
Claim the exemption with the Maryland Department of Natural Resources when you bring the boat into Maryland, through a DNR licensing and registration service center.
Your permanent change of station orders, your military ID, and the boat’s out-of-state registration.
