(3) If the credit allowable for any taxable year exceeds the taxpayer's tax liability for that tax year, the taxpayer may carry forward and apply in any subsequent taxable year, the portion, as reduced from year to year, of those credits which exceed the tax for the taxable year; provided, however, that in no event shall the taxpayer apply the credit to the tax for any taxable year beginning more than 10 years after the taxable year in which EOHLC gives the commissioner written notification of completion of the certified housing development project. If the credit is transferred by the taxpayer, the carry over provisions applicable to the transferee shall apply.

A transferee shall use the credit in the year it is transferred. If the credit allowable for any taxable year exceeds the transferee's tax liability for that tax year, the transferee may carry forward and apply in any subsequent taxable year, the portion, as reduced from year to year, of those credits which exceed the tax for the taxable year; provided, however, that in no event shall the transferee apply the credit to the tax for any taxable year beginning more than 10 years after the taxable year in which EOHLC gives the commissioner of revenue written notification of completion of the certified housing development project.

(5) EOHLC may authorize up to $30,000,000 in credits annually under this section and subsection (q) of section 6 of chapter 62. EOHLC may authorize annually any credits under this section or said subsection (q) of said section 6 of said chapter 62 returned to EOHLC by a certified housing development project. The total amount of credits authorized during a year shall include:

1. (1) credits granted during the year under this section or said subsection (q) of section 6 of chapter 62; and (2) carry forwards of credits from prior years under this section or said subsection (q) of section 6 of chapter 62, to the extent that such credit carry forwards are estimated by the commissioner of revenue to offset tax liabilities during the year. Any portion of the $30,000,000 annual cap not authorized by EOHLC during a calendar year shall be added to the amount EOHLC may authorize in subsequent years. EOHLC shall provide the commissioner of revenue with any documentation that the commissioner deems necessary to confirm compliance with the annual cap and the commissioner shall provide a report confirming compliance with the annual cap to the secretary of administration and finance and the secretary of housing and livable communities.
2. (6) The commissioner of revenue, in consultation with EOHLC, shall adopt regulations necessary to carry out this section.
