Florida Statutes Title XIV. Taxation and Finance § 220.723. Overpayments; interest

(1) Interest shall be allowed and paid in accordance with the provisions of s. 220.807 upon any overpayment of a tax imposed by this chapter. However, if any overpayment is refunded or credited within 3 months after the date upon which the taxpayer files written notice advising the department of such overpayment, no interest shall be allowed on such overpayment.

(2) Interest shall accrue from the date upon which the taxpayer files a written notice advising the department of the overpayment. Interest shall be paid until such date as determined by the department, which shall be no more than 7 days prior to the date of the issuance by the Chief Financial Officer of the refund warrant.

(3) For purposes of this section, no amount of tax for any taxable year shall be treated as having been paid before the date on which the tax return for such year was due under applicable law or the date the payment was actually made, whichever is later.
