An adjustment is a correction of a payroll detail from a previously submitted report. 

All adjustments must be submitted separately in an adjustment report.

You may have to complete an adjustment due to (but not limited to):

  • A missed or incorrect pay reported on a previous submitted payroll
  • An incorrect job classification
  • Failure to report termination information on a previous payroll
  • Retroactive payment for employee exceeding $900.00 per pay date

To learn how to complete an adjustment, view the adjustments instructional video or the written step by step instructions.
