Starting January 1, 2012, the IRS requires preparers who anticipate preparing more than 10 Federal individual or trust tax returns during the year to file these returns electronically. If the preparer is a member of a firm. this requirement applies to the firm's total number of returns filed.
Form 8948, Preparer Explanation for Not Filing Electronically, is also available for other reasons for not E-Filing such as Taxpayer does not want to E-File their return.
This Form should be used to explain the reason you cannot meet the above requirements for a federal or trust tax return that you prepared for your client. Form 8948, must be attached to the tax return that is mailed to the IRS. A copy of this form should also be provided with your clients copy of their individual or trust tax return.
Per the IRS FAQ:
14. Can my clients choose not to e-file?
Yes. Even if you are a specified tax return preparer, your clients may independently choose to file on paper. Preparers should document each client?s choice to file in paper format and keep a signed copy of the statement on file. See below for recommended language for this statement. Do not send the statement to the IRS or attach it to the client?s tax return. Instead, attach Form 8948, Preparer Explanation for Not Filing Electronically, to your client?s paper return and check box 1. Include your PTIN on each tax return where requested.
