Submitting files

Before you process a file you must complete Form 967 located in CFS Payroll System under ''W-2/1099 Information Returns'' and save the form. Save Form 967 with only W-2 state withholding data. If the employer also has state withholding from 1099s, save that data as a separate file. When you process the file you will be given the option to select a saved Form 967 that corresponds to the W-2 data in the file. The electronic file contains all of the data from the Form 967 so do not submit a paper copy to the state when filing W-2s electronically.
