important

  • You must be using ReadyPay version 3.74.0.18 to get the tax updates.

  • There are three high impact tickets in this update. Federal 940 MeF has new required data elements. See TAPS-915 for details. Federal 943, 944, and 945 MeF have new required data elements. See TAPS-916 for details. The updated MeF formats include a Vendor Control Number, which EarnIn is required to assign to each service bureau that uses ReadyPay to create and submit these eFiles. EarnIn must also record each service bureau's EFIN before the VCN can be assigned. These changes do not apply to the Q4 Federal 941. W-2 Pressure Seal format now has the correct font size. See TAPS-988 for details.
