A TCC is NOT required. If you don't have a TCC enter 5 zeros for the TCC on the Transmitter Screen. The TCC will be formatted as blanks in the file.

If filing electronically, first determine whether you will file as a Tax Preparer for multiple employers in one file (requires registration as a Third Party Bulk Filer), or as an Employer/Payer.
