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 R0000-015-01: ("PreparerFirmEIN") in the Return Header must not equal all nines.
