The Internal Revenue Service will simplify the signature process for electronically filed individual income tax returns submitted by tax practitioners. The simplification eliminates the need for a paper signature document to be sent to the IRS in support of electronically filed tax returns.

Beginning with the 2008 filing season, tax practitioners can e-file individual income tax returns only if the returns are signed electronically using one of two methods: either a Self-Select Personal Identification Number (PIN) or a Practitioner PIN. A Self-Select PIN allows taxpayers to electronically sign their e-filed return by selecting a five-digit PIN. A Practitioner PIN is used when a taxpayer authorizes an Electronic Return Originator (ERO) to input an electronic signature on behalf of the taxpayer.

Practitioner PINs require the use of Form 8879, IRS e-file Signature Authorization, which is retained by the ERO.
