Keystone CSV File Specification

The Keystone CSV File Specification format can be used to submit EIT or LST information to Keystone Collections Group. Use this 'comma separated value' format to submit either EIT or LST withholding information for one employer workplace location. If you need to submit both EIT and LST withholding information for a single workplace location, you will need to submit separate EIT and LST files.
