221.02  Credit for emergency excise tax paid.--The emergency excise tax paid pursuant to s. 221.01 plus any credit or carryover properly applied to reduce the amount of the emergency excise tax due for the taxable year shall be allowed as a credit against the emergency excise tax, if any, to be charged and collected pursuant to this chapter for the return filed for the fifth taxable year following the taxable year for which the tax was paid or, if earlier, the taxable year for which a final return is required. To the extent that the credit exceeds the emergency excise tax, if any, for the return filed for the fifth taxable year following the taxable year for which the tax was paid or, if earlier, the taxable year for which a final return is required, such excess shall be allowed as a reduction of, and credit against, any tax imposed by chapter 220 upon the taxpayer for the fifth taxable year following the taxable year for which the tax was paid or, if earlier, the taxable year for which a final return is required. If the taxpayer is unable to fully utilize the credit in the year in which it is first allowed, it may be carried over to each of the 5 taxable years immediately thereafter.
