When a non-custodial parent has more than one case with DCS, the law tells DCS how to split up a support payment between cases. It is based on a percent-of-total basis.
Current support is paid first. If a payment does not equal the total amount owed for all the non-custodial parent's cases, DCS divides the payment proportionately. Once current support for the month is paid, DCS applies amounts over current support to back support owed.
IRS tax refund intercept payments are an exception to this rule. These payments may only be applied to back support owed, and they are always applied to state debt owed before debt owed to the custodial parent.
Between October 1, 2008, and June 30, 2010, DCS applied IRS tax refund collections to both current support and arrears. These collections applied first to the debt owed to the custodial parent and then to state debt.
Beginning July 1, 2010, DCS applies tax-refund offset collections to debt as it did before October 1, 2008. This change back to the pre-October 2008 distribution rules is based on budget decisions made by the Washington State Legislature during the 2010 session.
Back support payments are also proportioned based on a percent of total. If you received public assistance in another state that has asked DCS to collect back support, that case will receive a percent of the back support payment. When DCS is providing payment processing services only (PSO) on one of the cases, the non-custodial parent must send payments and indicate that a payment is for the PSO case only. Otherwise, DCS will apply payments proportionately to the non-PSO cases.
