the taxpayer shall deliver to the purchaser or transferee a written statement that the
taxpayer has elected not to claim the credit and that the purchaser or transferee may
claim the credit, subject to the conditions and limitations prescribed by this section.


D. If the allowable credit exceeds the taxes otherwise due under this title on the
claimant's income, or if there are no taxes due under this title, the amount of the
credit not used to offset taxes under this title may be carried forward to the next five
consecutive taxable years as a credit against subsequent years' income tax liability.
