45 CFR § 305.34 - Payment of incentives.
(a) Each State must report one-fourth of its estimated annual incentive payment on each of its four quarterly collections' reports for a fiscal year. When combined with the amounts claimed on each of the State's four quarterly expenditure reports, the portion of the annual estimated incentive payment as reported each quarter will be included in the calculation of the next quarterly grant awarded to the State under title IV-D of the Act.
(b) Following the end of each fiscal year, HHS will calculate the State's annual incentive payment, using the actual collection and expenditure data and the performance data submitted by December 31st by the State and other States for that fiscal year. A positive or negative grant will then be awarded to the State under title IV-D of the Act to reconcile an actual annual incentive payment that has been calculated to be greater or lesser, respectively, than the annual incentive payment estimated prior to the beginning of the fiscal year.
(c) Payment of incentives is contingent on a State's data being determined complete and reliable by Federal auditors.
