Trying to understand state use taxes. Do states tax or impose a fee on out of state boats that are moored in that particular state for extended periods of time? I'm from Florida and was thinking of docking my boat in a GA or SC marina for a month or 2 this fall. Will I have to pay that state a use fee?
Every state has different rules. However, typically registration is the first sign of something needing to be done and most states allow you to be on their waters continuously for up to 60 or even 90 days before you're required to register. You can and may have multiple registrations in a year. However, if you're in GA for 59 days and then SC for 59 and then back to GA for 59 and on to FL you'd not have to register in either GA or SC.
Why do I mention registration first? Because that's what triggers sales or use tax. If you had to register in another state, you would then be subject to their rules on sales and use tax. However, having to pay anything is unlikely unless it's a new boat. They provide exclusions based on sales taxes you paid in other states, based on time of ownership, and based on other factors.
As an example, if you bought a boat and paid FL sales tax and moved it to GA permanently the following day and you were a GA resident, then you might have to pay additional use tax for the difference in GA and FL sales taxes on the boat. But that isn't your situation. You're not a GA resident. You've owned and used the boat in FL, so highly unlikely you'd be assessed any use tax in any other state.
Registration fees are generally small. The only other tax you might be subject to is property tax but that's just in certain states and has it's own set of rules. It typically requires the boat there on January 1 and that state to be your principle place of use. Again, each state with it's own rules.
I've never personally known a cruiser of a properly registered boat to be assessed any sales or use tax in another state. I've known a few cruisers to be required to register their boat in other states. Some states and even counties are more diligent than others. Keep marina and fuel records to show how long you've been there.
