The very first sentence in the ProSeries' tutorial for Using eSignatures with Business Returns is: "Be aware of IRS guidelines for collecting signatures for business forms." When I click on the hyperlink, it takes me to a IRS Office of Chief Counsel Memorandum which states that the IRS has only authorized the use of "alternative signature methods on the Form 8879 for Individual tax returns and not other members of the Form 8879 family relating to business returns." It further references the need for "manual signatures" on business tax returns. If this is the case, why is ProSeries saying that eSignature is available for business tax returns?
