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 F1040SSPR-507: 'QualifyingChildSSN' on Form 1040-SS (PR), Part I, Line 2(b) was used as 'QualifyingChildSSN' or 'DependentSSN' in a previously accepted tax return for the same tax period.

Here is a situation where a dependent has already been claimed on another tax return. Remove the dependent to be eligible to electronically file the return. If the taxpayer believes the reject is in error they can leave the rejected dependent listed on the return and mail a paper return.
