EXAMPLE: The administrative housing agency issues a reservation letter for a qualifying project in December 2003. A calendar-year donor makes a qualifying donation in January 2004. Under this subsection (c), the donor may elect to take the credit in 2003 or 2004. If, in 2008, the donor transfers any unused credit to a calendar-year taxpayer, the taxpayer may also elect to claim the transferred amount as a credit in 2003 or 2004. However, because the statute of limitations might prevent the taxpayer from deriving any benefit from claiming the credit in 2003 or 2004, subsection (c)(3) allows the taxpayer to claim the credit in 2008, the year of the transfer. If the taxpayer elects to claim the credit in 2008, it may carry forward any credit in excess of its liability only until 2009, 5 years after the year of the donation.
