IRS Overpayment Interest Overview

20.2.4.1  (03-01-2002)
Overpayment Interest Overview

  1. Per IRC section 6611(a), interest is allowed and paid on any overpayment of tax at the overpayment rate established under IRC section 6621.

  2. The allowance of interest is authorized only on overpayments. There is no overpayment until the entire tax liability is satisfied.

  3. The Restructuring and Reform Act of 1998 (RRA '98) eliminated the interest rate differential for non-corporate taxpayers. See IRC 6621(d).

  4. Credit interest is allowed if the overpayment is:

    1. offset against a liability.—IRC section 6611(b)(1). See Section 4.6.1., or

    2. refunded to the taxpayer.—IRC section 6611(b)(2). See Section 4.9..
