EFIN Acceptance Letter Requirement

New for tax year 2013: All TaxACT Professionals are required to submit a copy of their IRS EFIN acceptance letter to TaxACT for verification.

This one-time verification process needs to be completed for each EFIN used in your office. You may submit a copy of your EFIN acceptance letter two ways:

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

It is important to submit your EFIN acceptance letter now, to avoid tax-time processing delays. Until your EFIN is verified, any 2013 returns you submit will be rejected. Once we receive your EFIN acceptance letter and verify your information, your returns will be processed as usual. Any returns submitted prior to EFIN verification will need to be resubmitted.
