⚠ If something goes wrong
This form allows someone who prepares your tax return electronically to sign it on your behalf. It formally authorizes that preparer, called an ERO, to enter or generate your Personal Identification Number (PIN) for the Form 4547. The ERO must complete this form when filing your e-return.
An Electronic Return Originator (ERO) must complete IRS Form 8879-TA when they file an e-filed Form 4547, either because the Practitioner PIN method is used or because the individual authorizes the ERO to enter/generate their PIN.
The form collects information identifying the taxpayer on Part I of Form 4547. It also records the authorization details and signatures in Part II, with Part III completing the Certification and Authentication for Practitioner PIN Method returns.
Form 8879-TA must be completed when an ERO is filing a Form 4547; specifically, if using the Practitioner PIN method and authorizing the ERO to generate the PIN (completing Parts I, II, and III).
The ERO does not send IRS Form 8879-TA to the IRS unless requested; instead, the ERO must retain it. The form is provided to the individual identified on Part I via hand delivery, U.S. mail, private delivery service, email, internet website, or fax.
First, the ERO enters the name and SSN of the individual on Part I. Next, they complete Part II by entering or generating the PIN. If using the Practitioner PIN method, the ERO must also complete Part III, which includes their six-digit EFIN followed by five-digit self-selected PIN.
If the ERO fails to provide a copy of the signed Form 8879-TA upon request, the taxpayer may not have proof of authorization. The ERO must retain the form for 3 years from the return due date or IRS received date, whichever is later.
The general instruction is not to submit Form 8879-TA, but it must be sent if the IRS specifically requests it. Confirm that the ERO must retain the completed form.
