Income Tax Q&A: IRS Form 8879

What is form 8879?

Form 8879 is an electronic signature document that is used to authorize e-filing. It is generated by the software using both the taxpayer’s self-selected PIN and the Electronic Return Originator’s (ERO’s) Practitioner PIN. Form 8879 does not need to be mailed to the IRS but instead is retained by the ERO, in this case, Xendoo.

Who must sign an 8879?

When you use a third-party tax preparer, you are required to review and sign the 8879.

What is important to note when signing the 8879?

At the top of the 8879 is a lot of filled information used to identify you and summarize your tax return information. It’s important to note when you sign your 8879, you are certifying that all the names, SSNs, and amounts are correct.

Where can I find the 8879?

For Xendoo customers, we will provide you with an 8879.  Otherwise, you can find it on the IRS website here. Look at this link

It’s important to read the first line of Part II. Here it is for your convenience:

Under penalties of perjury, I declare that I have examined a copy of my electronic individual income tax return and accompanying schedules and statements for the tax year ending December 31, 2019, and to the best of my knowledge and belief, they are true, correct, and complete.

This is where the tax party is certifying, under penalties of perjury, that your entire tax return and accompanying schedules and statements are “true, correct, and complete.”

What is the role of the CPA?

Our responsibility as tax preparers is to provide a tax return that is accurate, given that the information you provide us is accurate. We may be tax experts, but we can’t read your mind. We don’t know if you’re holding any information back, even accidentally. This is one of the reasons we ask a lot of questions such as: Have you bought or sold a house in the last year?  Is this all your income?

Undeclared income is something that gets a lot of people in trouble, and we can only do so much to assess whether you are declaring all of your income. Errors of omission often happen by accident of course.

What are the Taxpayer Responsibilities?

On page two you will find the following instructions and fine print.

Most of these instructions are procedural, but please note the phrasing of Item 1:

Taxpayers have the following responsibilities.

1. Verify the accuracy of the prepared income tax return, including direct deposit information.
