Electronic Filing of W-2 and 1099 Documents

Employers and Agents

W-2 and 1099 tax documents may be sent to the Montana Department of Revenue electronically via our File Transfer Service (FTS), a component of the State’s ePass service. If you have already established an ePass account for other purposes, you can activate FTS using the username and password you created previously. Otherwise, you can establish an account now by going to either of these links:

or by calling the Department of Revenue at (406) 444-6900 for personal assistance.

FTS is a secure system that incorporates encryption prior to performing the transfer.

File Properties

W-2 documents must be created using the most current version of the EFW2 format as defined by the Social Security Administration.
