On January 24, 2018, the Supreme Court adopted revisions to the Arizona Child Support Guidelines based in part on recent changes to state law increasing the minimum wage and new federal regulations. No updates or changes were made to the underlying Schedule of Basic Support Obligations. The 2018 child support guidelines are effective for all child support orders, whether original orders or modifications of previous orders, entered after March 31, 2018, except in cases of default or as otherwise agreed upon by the parties. (Arizona Guidelines and Administrative Order 2018-08). Note: For those who earn minimum wage in states other than Arizona, a new field has been added that will automatically calculate the self-support reserve amount. In 2019, the calculator was updated to include the increase to minimum wage in the automatic calculation of the self-support reserve amount for 2018 or 2019.
