The State must calculate and promptly pay incentives to political subdivisions as follows:

(a) The State IV-D agency must develop a standard methodology for passing through an appropriate share of its incentive payment to those political subdivisions of the State that participate in the costs of the program, taking into account the efficiency and effectiveness of the activities carried out under the State plan by those political subdivisions. In order to reward efficiency and effectiveness, the methodology also may provide for payment of incentives to other political subdivisions of the State that administer the program.

(b) To ensure that the standard methodology developed by the State reflects local participation, the State IV-D agency must submit a draft methodology to participating political subdivisions for review and comment or use the rulemaking process available under State law to receive local input.
