y'all can do what i did and renounce your Hawaii LEGAL residency,
and switch residence to a state where they don't tax your ass to death.
I still live here, I just can't vote here.
My vote never counted anyway so no loss.
This only works if you have a wife here and a mainland Physical residence.
I can buy guns and ammo at lots of gun shows, no permission needed.
How, exactly, did you establish residency somewhere other than the state in which you actually reside?
Are you active military?
Do you spend more than 180 days living/working outside of Hawaii?
Do you receive the majority of your taxable income from sources in another state?
Even if you're military, you have to have a physical presence in whatever state you claim for legal residence, such as your verifiable address, state driver's license, registration of vehicles, and voter registration. You either have to live there or make it reasonably obvious that you'll be retiring there when no longer active duty.
I truly hope you never get audited by the state or federal tax man unless you've covered your bases. Penalties and interest are a bitch.
