Establishing when you became a Florida resident for tax purposes hinges on several key factors. The primary considerations are physical presence and domicile.
You must be physically present in Florida for at least 183 days during the taxable year—more than half the year. Keeping a detailed log of days spent in Florida versus your former state is essential if you relocated mid-year.
Domicile refers to your permanent home, where you intend to remain indefinitely. You can have only one domicile at a time. Actions that demonstrate intent to establish Florida domicile include purchasing a home, registering a vehicle, obtaining a Florida driver's license, and registering to vote in the state.
Tax authorities also examine where you file state income tax returns, the location of bank accounts and investments, your place of employment or business, where your children attend school, and your spouse's residence.
