Limitations.

No credit may be claimed under this subsection unless the claimant submits with the claimant’s return a copy of the claimant’s certification by the department of commerce under s. 560.28, 2009 stats., except that, with regard to credits claimed by partners of a partnership, members of a limited liability company, or shareholders of a tax-option corporation, the entity shall provide a copy of its certification under s. 560.28, 2009 stats., to the partner, member, or shareholder to submit with his or her return.

Partnerships, limited liability companies, and tax-option corporations may not claim the credit under this subsection, but the eligibility for, and the amount of, the credit are based on the amount of their unused credits under s. 71.07 (3s). A partnership, limited liability company, or tax-option corporation shall compute the amount of credit that each of its partners, members, or shareholders may claim and shall provide that information to each of them. Partners, members of limited liability companies, and shareholders of tax-option corporations may claim the credit in proportion to their ownership interest.
