In claiming the credit and determining its proportionate share of the tax due and the tax paid by the qualifying entity, the person claiming the credit shall follow the concepts set forth in subchapter K of the Internal Revenue Code. Nothing in this division shall be construed to limit or disallow pass-through treatment of a pass-through entity's income, deductions, credits, or other amounts necessary to compute the tax imposed and the credits allowed under this chapter.
The credit shall be claimed in the order required under section 5733.98 of the Revised Code. Any unused credit shall be allowed as a credit in the ensuing tax year. Any such amount allowed as a credit in an ensuing tax year shall be deducted from the balance carried forward to the next ensuing tax year.
