Estimated Tax Rates

If the corporation owes more than $2,500 in Florida corporate income tax annually, estimated tax payments must be made on a Declaration/Installment of Florida Estimated Income/Franchise Tax (Florida Form F-1120ES ). Form F-1120ES may be filed electronically.

Generally, for tax years beginning prior to January 1, 2017, and for tax years ending June 30, the declaration or payment of estimated tax is due on or before the last day of the 4th month, the last day of the 6th month, the last day of the 9th month and the last day of the tax year. For tax years beginning on or after January 1, 2017, that end other than June 30, the declaration or payment of estimated tax is due on or before the last day of the 5th month, the last day of the 6th month, the last day of the 9th month, and the last day of the tax year.

If you underpay estimated tax, a penalty of 12% per year is charged. For more information, see Underpayment of Estimated Tax (Florida Form F-2220 ) and its instructions. 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 webpage.
