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.

Any Indiana return that is filed electronically must be signed by the taxpayer (and spouse) with a PIN. The return must also include the ERO’s PIN signature. Returns without the proper PIN data may not be filed electronically. Enter PIN information on federal Screen PIN.

Form IT-8879, the Electronic Filing Declaration signature document, follows federal Form 8879. This form is required when using the Practitioner PIN method. The form is also required under the Self-Select PIN method when the taxpayer authorizes the practitioner to enter the taxpayer’s PIN signature on the electronically filed return.

Form IT-8879 is not required under the Self-Select PIN method when the taxpayer and spouse enter their own PIN signatures on the electronic return.
