EFW2 or EFW2 format is a type of file used by employers and payroll providers to report w2 forms electronically with the SSA (Social Security Administration) . Each year the SSA updates the W-2 electronic filing instructions through what is called the “Specifications for Filing Forms W-2 Electronically” or EFW2. For example for tax year 2009 (w2’s reported in 2010) the SSA issued 2009 EFW2 specifications (EFW2 Tax Year 2009).
