Limitations.

No person may claim the credit under par. (b) unless the claimant includes with the claimant’s return a copy of the allocation certificate issued to the qualified development.

A partnership, limited liability company, or tax-option corporation may not claim the credit under this subsection. The partners of a partnership, members of a limited liability company, or shareholders in a tax-option corporation may claim the credit under this subsection based on eligible costs incurred by the partnership, limited liability company, or tax-option corporation. The partnership, limited liability company, or tax-option corporation shall calculate the amount of the credit that may be claimed by each partner, member, or shareholder and shall provide that information to the partner, member, or shareholder. For shareholders of a tax-option corporation, the credit may be allocated in proportion to the ownership interest of each shareholder. Credits computed by a partnership or limited liability company may be claimed in proportion to the ownership interests of the partners or members or allocated to partners or members as provided in a written agreement among the partners or members that is entered into no later than the last day of the taxable year of the partnership or limited liability company, for which the credit is claimed. Any partner or member who claims the credit as allocated by a written agreement shall provide a copy of the agreement with the tax return on which the credit is claimed. Except as provided in s. 71.745, a person claiming the credit as provided under this subdivision is solely responsible for any tax liability arising from a dispute with the department of revenue related to claiming the credit.
