Oklahoma

Note: After a 2 year moratorium on all state tax credits, this credit may be claimed for tax year 2012 and subsequent tax years, for eligible expenditures on or after July 1, 2012.

Oklahoma allows a contractor who is the primary builder of an energy efficient home or manufactured home substantially completed after December 31, 2005 to claim an income tax credit beginning in tax year 2006. The home must be under 2,000 square feet. Improvements eligible for the credit include energy efficient heating and cooling systems, windows, doors, roofs and insulation to minimize heat loss and gain.

The contractor can take a tax credit for the amount of the eligible expenditures, not to exceed $2,000 for a home that is between 20% and 39% above the International Energy Conservation Code 2003 or $4,000 for a home that is 40% or above of the Code. In addition, the heating and cooling efficiencies must meet the minimum requirements established by the National Appliance Energy Conservation Act of 1987 and building envelope improvements must account for a certain percentage of the reduced annual heating and cooling energy consumption levels.

The contractor can carryover any unused portion of the tax credit for up to four subsequent years. As the result of a 2006 amendment, credits earned after August 25, 2006 are freely transferable to any taxpayer upon the filing of a transfer agreement.
