  REQUIREMENTS:

  electronic filing.  Please include the RS records or talk to your programmer about including RS records 
  for employees who are taxable to the City of Lansing. The RS record MUST be included along with 
  the RW federal record.  RS record provides locality information; the codes used by other

  will be returned.

     CityTax Proprietary Format—CTP    
   
 1.    Acceptable media:  Data is to be submitted either by CD-ROM, USB DRIVE or EMAIL. Floppy disks are 
  no longer accepted and will be returned.  The file must be named W2REPORT and must be in the root

 2. If using the alternate CityTax Proprietary format a file extension of .csv must be attached    
    to the file. 
 3. If more than one file of W-2 information is being submitted, each file must be named as follows:   
    W2REPORT1, W2REPORT2, and W2REPORT3.

    line: W2REPORT and FEIN.  Attach the W2 report and LW3 report.   
  
 City Tax Proprietary Format (CTP) 
 This is a simple format for a single employer.  It may be created using Microsoft Excel; and should be in a 
 Comma Delimited format.  Details are listed on the following page.  
    All text must be in upper case.   
    If leading zeros on a Social Security Number or Zip code does not show, this is all right.  
    All dollar amounts should be entered as a normal number with a decimal point, such as 
        5100.50. 
    Do not leave blank lines between information. 
    Do NOT use column headings; start employer information in cell A1.
