Section 71.28 (5b) (e) to (h), as it applies to the credit under s. 71.28 (5b), applies to the credit under this subsection. Claimants shall include with their returns a copy of their certification for tax benefits and a copy of the department of commerce’s verification of their expenses.

The credit under this subsection may not be claimed by partnerships, limited liability companies, and tax-option corporations but the eligibility for, and the amount of, that credit shall be determined on the basis of their economic activity, not that of their shareholders, partners, or members. The corporation, partnership, or limited liability company shall compute the amount of credit that may be claimed by each of its shareholders, partners, or members and shall provide that information to each of its shareholders, partners, or members. That credit may be claimed by partners, members of limited liability companies, and shareholders of tax-option corporations in proportion to their ownership interests.
