Incorporating e-file Into Your Office

Final tips

Now that you know the process for e-filing returns, here are some final, important tips:

  • Attach paper forms and supporting documentation that are not included with the electronic return data to the California e-file Return Authorization (FTB 8453 form series) or the California e-file Signature Authorization (FTB 8879 form series) to complete the e-file return. For more information on retention of form FTB 8453 series or form FTB 8879 series and attachments, see FTB 1345, Handbook for Authorized e-file Providers , Section 7.
  • Provide an acknowledgement letter (along with a copy of their signed form FTB 8453 series or form FTB 8879 series) for all accepted returns to your clients. Your software may provide this option.
