Florida Statutes Title XIV. Taxation and Finance § 220.23. Federal returns

1. Shall show the taxpayer's name, address, and employer identification number;  the adjustments;  the taxpayer's revised net income subject to tax and revised tax liability under this code;  and such other information as the department may by regulation prescribe;

2. Shall be signed by a person required to sign the original return or by a duly authorized representative;  and

3. Shall be filed not later than 60 days after such adjustment has been agreed to or finally determined for federal income tax purposes, or after any federal income tax deficiency or refund, abatement, or credit resulting therefrom has been assessed, paid, or collected, whichever shall first occur.

1. A notice of deficiency may be issued at any time within 5 years after the date such notification is given;  or

2. If a taxpayer either fails to notify the department or fails to report a change or correction which is treated in the same manner as if it were a deficiency for federal income tax purposes, a notice of deficiency may be issued at any time;

3. In either case, the amount of any proposed assessment set forth in such notice shall be limited to the amount of any deficiency resulting under this code from recomputation of the taxpayer's income for the taxable year after giving effect only to the item or items reflected in the adjustment.

Interest in accordance with s. 220.807 is due on the amount of any deficiency from the date fixed for filing the original return for the taxable year, determined without regard to any extension of time for filing the original return, until the date of payment of the deficiency.
