The amount of the credit allowed in this section is the taxpayer's share of the credit the nonprofit organization or the unit of State or local government could claim under G.S. 105-129.16A if the nonprofit organization or government unit were subject to tax. The taxpayer's share of the credit is calculated by dividing the taxpayer's donation by the cost of the renewable energy property constructed, purchased, or leased by the nonprofit organization or government unit and placed in service during the taxable year and then multiplying this percentage by the amount of the credit the nonprofit organization or government unit could claim if it were subject to tax. A taxpayer must take the credit allowed by this section for the taxable year in which the property is placed in service. The installment requirements in G.S. 105-129.16A for nonresidential property do not apply to the credit allowed in this section.
