MFA required for electronic filing

Effective May 3rd, the 2017 version of UltraTax CS requires multi-factor authentication (MFA) to transmit e-files from CS Connect. Find out more.

An ETIN is an Electronic Transmitter Identification Number. To be a transmitter of electronic files, one must apply with the IRS, stating they are a transmitter and pass IRS compliance testing.

For example, Thomson Reuters is a transmitter; and therefore, would receive an ETIN. As a user of our software, you should not receive an ETIN, because you are not a transmitter of electronically filed returns, but rather an Electronic Return Originator (ERO). Hence, if you received an ETIN, you should contact the IRS at 866-255-0654 and have them update your records.
