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.

Error code R0000-004-01: 'ReturnTypeCd' (specified in the Return Header) and the return version (specified by the 'returnVersion' attribute of the 'Return' element) of the return must match the return type and the version supported by the Modernized e-File system.

The IRS supports the current year and two previous years of returns. Any return 3 years prior to the current filing season will receive this rejection.

Note: The IRS may update the electronic file schematic to accommodate prior year returns to be electronically filed. If they do, UltraTax CS needs to be updated to match the schematic. Download and apply updates if you receive this error when electronic filing a prior year return within 3 years of the current year.
