J.K. Lasser's Your Income Tax 2013: For Preparing Your 2012 Tax Return

48.8 Agreeing to the Audit Changes

After the audit, the agent will discuss proposed changes either with you or your representative.

If you agree with the agent’s proposed changes, you will be asked to sign a Form 870, which, when signed, permits an immediate assessment of a deficiency plus penalties and interest, if due. The Form 870 is called “Waiver of Restrictions on Assessment and Collection of Deficiency in Tax and Acceptance of Overassessment.”

If you believe that you have done as well or better than expected regarding the proposed deficiency, you can bring the case to a close by signing the Form 870, but the agent’s supervisor must also approve the assessment.

By signing the form, you limit the amount of interest charges added to the deficiency. A signed Form 870 does not prevent the IRS from reopening the case to assess an additional deficiency. If on review the deficiency is increased, you will receive a revised Form 870. You can refuse to sign the form. The signed first form has the effect of stopping the interest on the original deficiency. As a matter of practice, however, waivers of acceptances ordinarily result in closing of the case.
