Are federal forms and/or attachments allowed to be included in the electronically filed return?
A2. No. Only Massachusetts Department of Revenue official forms are allowed to be filed electronically. Q3. What is the first period of filing that would be required to be filed electronically for corporate and partnership returns and extensions? (i.e., are fiscal years ending 10/04 and 11/04 required to be filed electronically or will the mandate require only year ending 12/04 and thereafter?). A3. Tax year ending 12/31/2004 and thereafter.
