Change to CS Support service hours

Our Support department is closed on [[date]]. However, limited UltraTax CS phone support is available on that date from 9 AM - 5 PM ET due to the approaching deadline.

Links to our most popular tax processing topics are available in the Alerts and notices section on the right side of most pages.

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.
