When does eFileForBusiness file my forms with the IRS/SSA?
eFileForBusiness files your data electronically with the IRS/SSA on or before the March 31st electronic filing deadline. In cases where March 31st falls on a weekend or a Federal holiday, the deadline is automatically extended to the next business day. As an example, for the 2007 tax season the electronic filing deadline was April 2nd, 2008. You can edit your forms until such time that they are electronically submitted to the IRS/SSA.
