EFIN Verification Requirements

All TaxAct Professionals are required to submit a copy of their IRS e-file application summary to TaxAct for verification. If you were verified for tax year 2013 or 2014, you do not need to resubmit your documentation.

This one-time verification process needs to be completed for each EFIN used in your office.

You may submit a copy of your IRS e-file application summary two ways:

  1. Email: EFINcertificate@taxactservice.com (preferred)
  2. Fax: 319-447-4674 (Attention: EFIN Verification)

It is important to submit your EFIN documentation now, to avoid tax-time processing delays. Until your EFIN is verified, you will receive a pop-up reminder to submit your information each time you proceed through the e-file process.
