15-31-125. Determination of tax credit. A new or expanding manufacturing corporation may receive an income tax credit based on a percentage of wages paid its new employees within this state for a period of 3 years as provided in this section. For the first 3 years of operation of a new corporation or the first 3 years of expansion of an expanding corporation, a credit of 1% of the total new wages paid in this state, as wages are defined in 39-51-201, may be allowed. In determining total wages for an expanding corporation, only those wages paid in support of the expansion are considered in ascertaining the credit. The payroll and number of jobs of the corporation in the 12-month period immediately preceding the expansion are averaged to determine eligibility for the credit.
