Florida Corporate Income Tax

For businesses whose fiscal year corresponds to the calendar year this is due Apri 1.

Corporations doing business in Florida are subject to the 5.5% tax. C-corporations pay the tax on form F-1120. If a corporation owes more than $2,500 annually in Florida corporate income tax, it must make estimated tax payments on form F-1120ES on or before the last day of the fourth, sixth and ninth month of the taxable year and the last day of the tax year. If the business has zero tax or owes less than $2,500 in tax, it may file the short form, F-1120A.

Limited liability companies classified as a corporation for federal tax purposes must file a Florida corporate income tax return. Limited liability companies that are classified as partnerships for federal tax purposes are required to file a Florida Partnership Information Return (form F-1065) if they are doing business in Florida and one or more of their owners are corporations. In addition, the corporate owner of an LLC that is classified as a partnership for Florida and federal income tax purposes must file a Florida corporate income tax return.

S-corporations in Florida usually do not have to file a Florida corporate income tax return unless there is federal taxable income.
