EFIN Verification Requirements

All TaxAct Professionals must submit a copy of their IRS e-file application summary that includes their tracking number to TaxAct for verification. This one-time verification process needs to be completed for each EFIN used in your office. If your EFIN has been verified by TaxAct in a previous year, you do not need to resubmit your documentation.

To submit your documentation:

  1. Sign in to your IRS e-Services account and print your e-file application summary with your tracking number.
  2. For fastest verification, email your summary to EFINcertificate@taxactservice.com. (Alternatively, you can fax to 319-447-4674, Attention: EFIN Verification.)
  3. You will receive an email from TaxAct as soon as your EFIN information has been verified.

It is important to submit your EFIN documentation now to avoid tax time processing delays.
