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, you do not need to resubmit your documentation.

This one-time verification process needs to be completed for each EFIN used in your office. It is important to submit your EFIN documentation now to avoid tax time processing delays.

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.
