(1) Beginning with taxable years ending in 2012, a taxpayer who has earned, but not yet taken, a credit for emergency excise tax paid under former s. 221.02 may take such credit against the tax imposed by this chapter.
(2) If a credit granted pursuant to this section is not fully used in taxable years ending in 2012 because of insufficient tax liability on the part of the taxpayer, the unused amount may be carried forward for a period not to exceed 5 years. The carryover credit may be used in a subsequent year when the tax imposed by this chapter for such year exceeds the credit for such year, after applying the other credits and unused credit carryovers in the order provided in s. 220.02(8).
