Becoming a Florida resident is simple and easy. Let's take a typical Florida locale like, choosing at random, Martin County, FL. First, you need an address. You can easily pick up a cute little condo, especially now that Florida real estate prices have tanked more than most parts of the country. For example, a 1300 square foot condo on the water would have cost you $105,000 two years ago. Today, it's assessed at only $75,000.
And with a little looking, you could probably find an even cheaper place to hang your tax return. RealtyTrac lists 143 bank-owned properties just in Stuart, FL alone. Twelve of them are listed for less than $50,000, including one gem on Ocean Boulevard that can be yours for just $28,720! And you could do even better - there are 32 Stuart properties coming up for Sheriff's Sale.
You automatically become a Florida resident by (a) getting a Florida job; (b) sending your kids to a Florida school; or (c) registering to vote. You can file a simple Declaration of Domicile form, showing a phone or utility bill and a picture ID to establish that you have an honest to God Florida residence. You will need to file your federal income taxes from your Florida address.
