    • Knowledge-based authentication (KBA):

      Knowledge-based authentication, also known as KBA, is an identity verification measure that requires end users to establish their identities through the use of specific security questions. The e-signature option is only available to taxpayers e-filing their tax returns through an Electronic Return Originator (ERO), who uses software that provides identity verification and e-signature functionality. To meet e-signature requirements, the ERO must be able to record the taxpayer’s name, social security number, address and date of birth electronically for identity verification purposes. As part of identity verification, the software may create what is known as a “soft inquiry” in the credit reporting industry. A soft inquiry is not a credit check, although it is conducted by a credit reporting company that uses information from the taxpayer’s credit report to generate knowledge-based authentication questions. Typically, the knowledge-based authentication questions address the taxpayer’s personal and financial history. These are usually multiple-choice questions such as the name of their mortgage lender, type of car financed, a former address or phone number. The taxpayer is expected to answer the questions correctly. Taxpayers who cannot complete the identity verification check cannot use e-signature. Ordinarily, knowledge based authentication is not mandatory for envelopes which do not contain Form 8878 or 8879 or their state equivalents.
