MFA required for electronic filing

Effective May 3rd, the 2017 version of UltraTax CS requires multi-factor authentication (MFA) to access the electronic filing transmission feature in CS Connect.

Thomson Reuters is committed to proactively evolving our security features to help you protect your firm and your clients' data. For more information about multi-factor authentication, see Multi-factor authentication overview.

Are the fields designated as (ELF only) required for electronic filing?

Unlike the (Mandatory for electronic filing) fields, the (ELF only) fields are not required for e-file.

These are continuation fields and should be used only if the full address will not fit on Address Line 1, Business name on Business Line 1, etc.
