W-2 and 1099 Frequently Asked Questions
There are three primary ways to file withholding information electronically:
- Online Input Forms - Filers are able to input KW-3, W-2 and 1099 information using online forms. Only fields that are required are enterable.
- Comma Separated Value (CSV) File Format - Filers can upload W-2 and 1099 reports from correctly formatted CSV files. The fields to be included are outlined in the specification documents available on the Department's web site, www.ksrevenue.org/eservw2.html.
- Fixed Width Field File Format - Filers can submit Kansas withholding reports in the same file formats outlined by the Social Security Administration and the Internal Revenue Service. Similar to the CSV process, filers upload fixed width files directly into the Department's web system. File specifications are provided in the "Kansas W-2 Specifications for Electronic Filing" document available on the Department's web site, www.ksrevenue.org/eservw2.html.
