The MeF system describes tax forms in terms of XML and supports web-based filing. Modernized e-File was originally introduced in 2004, exclusively for corporate tax returns. Initially, there was only support for Form 1120 and related forms, but each year additional corporate tax forms were supported.<ref name=":0">{{Cite web|url=https://www.irs.gov/uac/modernized-e-file-overview|title=Modernized e-File (MeF) Overview|last=|first=|date=|website=irs.gov|publisher=Internal Revenue Service|access-date=2016-09-04}}</ref>
