What should I enter if I have a state ELF critical diagnostic requiring an officer SSN when the officer is a foreign citizen and/or doesn't have a social security number?


The IRS advises preparers to enter 888-88-8888 in the officer SSN field for officers without a social security number. In UltraTax CS, enter this in the Social security number for eSignature field on Screen Contact in the General folder.
