Kiwa, you should understand that the US is a "federal republic" of 50 sovereign states, not one nation at all for many purposes.
We have state motor
vehicle and/or boat registration in each of the States, with varying requirements in each of them.
And we have federal Vessel Documentation
, which is never referred to as "registration" here. The r-word is used only for matters of State registration, as a boat and/or motor
vehicle. (In most states, a boat with an engine
is simply considered a motor vehicle and treated the same as a car. Most but not all.)
So if the vessel has federal Documentation
, that becomes void as soon as an alien acquires more than a 50% ownership
of the vessel. But state registration applies to vessels kept within a state, without any concern for who owns them.
If your vessel is purchased, usually there will be state sales tax (or use tax) and sometimes personal property tax or other tax levied on the sale
or ownership of the vessel. That may come due at the time of the sale
, or it may not be due if the vessel is removed from the state within 30-90 days. The exact requirements and time periods WILL be different in every state.
The only way to be sure of what you will face, is to contact the authorities in the state the vessel is located in. (Although a broker usually will know the regulations
, their opinion is of course not legally controlling.)
In some states, brokers are required to collect sales or use tax at the time of sale, but private sellers are not. In some, there will be no tax if you are foreign-flagging the boat (or registering it to another state) and you get it out of the first state in 90 days or less. Again...you'll need to check state laws. Most of the states will have a "Department of Motor Vehicles" "Tax Department" or boats or marine
recreation, etc. department web site(s) with specific information. Those laws often change on January 1st, sometimes on other dates, so you need to make sure they are current
We have not VAT tax or federal taxes for you to worry about though. That's between you and Oz, along with any necessary duties.
