iv) The written request must be received by the Department within one year after meeting the criteria of this subsection (a)(1)(B) or, if applying for IV-D services, after the emancipation of the child, within one year after applying for IV-D services, provided that they meet the required criteria.
C) Effective January 1, 2021, interest on cases meeting the criteria of subsection (a)(1)(B) shall be calculated prospectively from the last judgment entered and contained in the Department's certified computer system or, if no judgment was entered, from the charges and payments, or balances, reflected and contained in the Department's certified computer system.

Subject to sub. (6m), if the party no longer has a current obligation to pay child support, interest at the rate of 1% per month shall accrue on the total amount of child support in arrears, if any.
