Florida corporate income/franchise tax is computed using federal taxable income, modified by certain Florida adjustments, additions, and subtractions, to determine adjusted federal income.

• A corporation doing business outside Florida may apportion its total income. Adjusted federal income is usually apportioned to Florida using a three-factor formula. The formula is a weighted average, designating 25% each to factors for property and payroll, and 50% to sales.
• You should add non-business income allocated to Florida to the Florida portion of adjusted federal income.
• You should then subtract an exemption ($50,000 as of December 31, 2015) to arrive at Florida net income.
• Finally, you should compute tax by multiplying Florida net income by 5.5%.

There are several credits available against the corporate income tax. These include credits for paying salaries in Florida, credits for paying other taxes or assessments, and credits for making certain types of investments in Florida. See the Corporate Income Tax Incentives page for a comprehensive list. The Florida Corporate Income/Franchise Tax Return (Form F-1120 ) and the instructions (Form F-1120N ) also provide a list and explanation of available credits each year.

Corporate income tax is reported using a Florida Corporate Income/Franchise Tax Return (Florida Form F-1120 ). Corporations must file Florida Form F-1120 each year, even if no tax is due. The due date is based on the corporation’s tax year.

Generally, Florida Form F-1120 is due the later of:

If you file your return or pay tax late, a penalty of 10% of any unpaid tax for each 30 days or fraction thereof, not to exceed a total penalty of 50% of unpaid tax, is charged. If no tax is due, the penalty for a late filed return is $50 per month or fraction thereof, not to exceed $300. A floating rate of interest applies to underpayments and late payments of tax. Interest rates can be found on the Department's Tax and Interest Rates web page.
