(b) Pays a minimum qualifying wage of eight dollars and twenty-five cents per hour to the new equivalent employees for which tax credits are sought under the Nebraska Advantage Rural Development Act. The Department of Revenue shall adjust the minimum qualifying wages required for applications filed after January 1, 2004, and each January 1 thereafter, as follows: The current rural Nebraska average weekly wage shall be divided by the rural Nebraska average weekly wage for 2003; and the result shall be multiplied by the eight dollars and twenty-five cents minimum qualifying wage for 2003 and rounded to the nearest one cent. The amount of increase or decrease in the minimum qualifying wages for any year shall be the cumulative change in the rural Nebraska average weekly wage since 2003. For purposes of this subsection, rural Nebraska average weekly wage means the most recent average weekly wage paid by all employers in all counties with a population of less than twenty-five thousand inhabitants as reported by October 1 by the Department of Labor. For purposes of this section, a teleworker working in Nebraska from his or her residence for a taxpayer shall be considered an employee of the taxpayer, and property of the taxpayer provided to the teleworker working in Nebraska from his or her residence shall be considered an investment. Teleworker includes an individual working on a per-item basis and an independent contractor working for the taxpayer so long as the taxpayer withholds Nebraska income tax from wages or other payments made to such teleworker. For purposes of calculating the number of new equivalent employees when the teleworkers are paid on a per-item basis or are independent contractors, the total wages or payments made to all such new employees during the year shall be divided by the qualifying wage as determined in subdivision (b) of this subsection, with the result divided by two thousand eighty hours.
