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.

Error Code F6781-026: If Form 6781, Line C 'MixedStraddleAccountInd' checkbox is checked, then   [MixedStraddleAccountElectionStatement] must be attached to Line C.

The above error occurs when a 1041 client files Form 6781 with box C "Mixed straddle account election" marked. In such a situation, the IRS is expecting an election statement which supports the selection made on Form 6781, box C to be included in the e-file. At this time, returns receiving this error must be paper filed.
