As you receive State Unemployment Insurance (SUI) Rate Change Notices from the state agencies, it is very important that this information is communicated to ADP. In order to avoid agency assessments, penalties or interest, please notify ADP of all new 2017 SUI experience rate amounts as soon as you may receive. For your convenience, please update the rate changes by accessing the ADP Support Center and following this path: Support Center> Payroll > Tools and Forms > Tax > SUI Rate Change.
