(1) For a tax imposed by any section of this chapter, a credit against the specific tax imposed by that section is allowed in an amount equal to a like tax lawfully imposed and paid on the same document or instrument in another state, territory of the United States, or the District of Columbia. For purposes of this subsection, “like tax” means an excise tax on documents that is in substance identical to the tax imposed by this chapter on the same document. The credit may not exceed the tax imposed by this chapter on the document. Proof of entitlement to such a credit must be provided to the department. The department may adopt rules to implement this credit and designate forms that establish what proof is required.
(2) The credit provided by this section applies retroactively. Notwithstanding the retroactivity of this credit provision, this section does not reopen a closed period of nonclaim under s. 215.26 or any other statute or extend the period of nonclaim under s. 215.26 or any other statute.
