(a) If the IRS determines that the payments by the taxpayer that are made within the period prescribed for payment and before the filing of the return exceed the amount of tax shown on the return (for example, excessive estimated income tax payments or excessive withholding), the IRS may credit or refund such overpayment without awaiting examination of the completed return and without awaiting the filing of a claim for refund. The provisions of §§ 301.6402-2 and 301.6402-3 are applicable to such overpayment, and taxpayers should submit claims for refund (if the income tax return is not itself a claim for refund, as provided in § 301.6402-3) to protect themselves in the event the IRS fails to make such determination and credit or refund. The provisions of section 6405 (relating to reports of refunds in excess of the statutorily prescribed threshold referral amount to the Joint Committee on Taxation) do not apply to the overpayments described in this section.

(b) Effective/applicability date. The rules of this section apply to payments made on or after July 24, 2015.
