Adjustments.

(1) If a taxpayer is required to amend its corporate income tax liability under chapter 220, or the taxpayer receives a refund of its workers’ compensation administrative assessment paid under chapter 440, the taxpayer shall file an amended insurance premium tax return not later than 60 days after such an occurrence.

(2) If an amended insurance premium tax return is required under subsection (1), notwithstanding any other provision of s. 95.091(3):

(a) A notice of deficiency may be issued at any time within 3 years after the date the amended insurance premium tax return is given; or

(b) If a taxpayer fails to file an amended insurance premium tax return, a notice of deficiency may be issued at any time.

The amount of any proposed assessment set forth in such a notice of deficiency shall be limited to the amount of any deficiency resulting under this code from recomputation of the taxpayer’s insurance premium tax and retaliatory tax for the taxable year after giving effect only to the change in corporate income tax paid and the change in the amount of the workers’ compensation administrative assessment paid. Interest in accordance with s. 624.5092 is due on the amount of any deficiency from the date fixed for filing the original insurance premium tax return for the taxable year until the date of payment of the deficiency.

(3) If an amended insurance premium tax return is required by subsection (1), a claim for refund may be filed within 2 years after the date on which the amended insurance premium tax return was due, regardless of whether such notice was given, notwithstanding any other provision of s. 215.26. However, the amount recoverable pursuant to such a claim shall be limited to the amount of any overpayment resulting under this code from recomputation of the taxpayer’s insurance premium tax and retaliatory tax for the taxable year after giving effect only to the change in corporate income tax paid and the change in the amount of the workers’ compensation administrative assessment paid.
