Industrial Disability Leave Supplementation Calculator

This Page Contains Information relevant to Personnel, Payroll and Accounting Offices

If you have Microsoft Excel, or a spreadsheet software application that can read an XLS file, you can download a spreadsheet that will do IDL Supplementation calculations.  This may be useful to State Personnel Offices if there were different tax rates used during the calendar year or if a salary rate reduction program is being used.
