What Is a Practitioner PIN?
Online filers, including customers of efile.com, do not need to worry about a Practitioner PIN. A Practitioner PIN is only used when a taxpayer physically visits an authorized tax practitioner and signs Form 8879, IRS efile Signature Authorization, which authorizes the practitioner to efile for the taxpayer. Again, you do not need this PIN when preparing your taxes on efile.com.
