Nonresident vessel permits

Intended audience: Nonresident vessel owners.

Washington law provides that a properly registered nonresident vessel is not subject to Washington registration requirements or use tax if the vessel is used in Washington for no more than 60 calendar days during any continuous 12-month period. Generally, nonresident vessel permits may be purchased to extend the time of use in this state without incurring a Washington registration obligation, and in some cases without a use tax obligation.
