The state of Idaho adjusts withholding rates as needed. HRMS has been updated with the new Idaho tables. Per Idaho’s guidance, when they issue a new table, processors do not need to adjust withholding back to the beginning of the year, rather just use the revised table going forward.
Further information regarding Idaho’s withholding tables, supplemental wages rate, and the ICTCAT can be found on the Idaho State Tax Commission website.
