How long before you're considered a resident of a state?

Thank you this is good info. I figure I have to pay the state income taxes, that's only fair. What I'm more worried about is having to become a resident of the state I'm working in. I want to be domiciled in Florida but I want to work all over. I'm fine with paying the taxes.

Yep, you'll have to pay state income taxes wherever you work. Every state I've had to file for had options for part-time or non-residents. Be careful about the states you work in. Some may want to tax you on all your income, or at least with a formula based on all your income.

As far as being considered a resident, vehicle registration, etc, I believe that is determined based on intent. If you're working for a temp agency, your intent is not to stay there permanently. Your house has wheels. You have a permanent address in another state and/or a domicile letter.

Regardless of your 'residency' or 'domicile' State IF you earn money/income in a State you will most likely have to file State Income Tax forms with each State.
As to taxes.....that would depend on amount of monies earned.

This is something you would need to research each States residency & possible tax consequences.

After tax season is over.....make an appointment with any H&R Block Agent.
Will cost you a few bucks but they can access each States requirements.

So all these people who work while full-timing are becoming residents of the states they work in?

I think states normally have you divide the year, for tax purposes. So if you live and work in state A for 3 months and state B for 6, you pay taxes to A for the 3 months and to B for the 6.

Which sounds like a lot of paperwork.

IN Texas, you are a resident if;

1- You get a job here
2- You get a drivers license here
3- You live here more than 10 days

this info on Turbotax might help.

You need a CPA not a RV forum. I'm sure there are exclusions but if you are in a state and have an address and earning money you are a resident.

As long as you want as long as you have established residency in your home state and have a permanent address in your home state. It also helps to have your vehicles registered in your home state and a bank account in your home state.
