Many large employers or payroll service providers find it convenient to file quarterly wage reports using magnetic media. Using magnetic media permits agents or payroll service providers to submit reports for more than one employer on a single diskette or compact disc (CD).

Acceptable types of magnetic media are:

  • Diskette - MS-DOS compatible, ASCII text format - 3-1/2" double-sided/double-density or double-sided/high-density diskette
  • CD - PC compatible, ASCII text format

Acceptable format:

  • ICESA Format published by the Interstate Conference of Employment Security Agencies (275 byte records) with fields defined for use by TWC is accepted on CD or diskette.

Employers who submit their quarterly reports through magnetic media will not have their diskettes or CD returned, and they will not receive a preprinted Employer’s Quarterly Report (Form C-3).
