1. The credit under this subsection may not be claimed for any amount of the federal employer-provided child care credit claimed for any expenditure paid or incurred for a child care facility located outside this state or for services provided outside this state. 2. A claimant who claims a credit under this subsection and whose federal income tax is increased under section 45F (d) of the Internal Revenue Code shall add to the claimant’s liability for taxes imposed under s. 71.23 an amount equal to the amount that the claimant’s federal income tax is increased under section 45F (d) of the Internal Revenue Code. 3. 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 amounts of the federal employer-provided child care credit claimed under par. (b). 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 interests.
