The Florida corporate income/franchise tax is imposed on all corporations for the privilege of conducting business, deriving income, or existing within Florida. Corporations, including entities that are taxed federally as corporations, are subject to the tax.

A corporation’s federal income, as adjusted by Florida additions, subtractions, and adjustments, is apportioned to Florida based on the corporation’s activities in Florida compared to its activities everywhere. In most cases, this comparison includes the corporation’s property, payroll and sales.

Who Must File?

• Every bank and savings association doing business, earning income, or existing in Florida.
• All associations or artificial entities doing business, earning income, or existing in Florida.
