Introduction Section 1224, of the Taxpayer Relief Act of 1997, requires partnerships with more than 100 partners (Schedules K-1) to file their return on magnetic media (electronically as prescribed by the IRS Commissioner). This law became effective for partnership returns with taxable years ending on or after December 31, 2000. Partnerships with 100 or less partners (Schedules K-1) may voluntarily file their return using the MeF Platform. This Web site provides an overview of electronic filing and more detailed information for those partnerships that prepare and transmit their own income tax returns using MeF. Partnerships that rely upon third party tax professionals to prepare and transmit their tax returns should consult their tax professional.
