delivered the opinion of the court:
The plaintiff sues to recover interest in the sum of $28,-448.97. The question presented is whether the Commissioner of Internal Kevenue properly computed interest on a 1941 income tax overpayment due to general adjustments. Both parties have moved for summary j udgment.
The undisputed facts may be summarized for the purposes of this decision as follows: The plaintiff duly filed-its income and excess profits tax returns for the years 1941 through 1945, and paid the taxes shown due thereon. For 1942,1943, Í944 and 1945, the excess profits tax returns showed no taxes due, which resulted in unused excess profits tax credits for those years and the carryback of such unused credits from 1942 and 1943 to 1941.
On October 12, 1943, the plaintiff filed a claim for refund of excess profit taxes for 1941 based upon a carryback from the year 1942 of an unused excess profits tax credit. The Commissioner audited the plaintiff’s returns and made various adjustments attributable to the carrybacks, and also made general adjustments including the allowance of an income tax overpayment in the amount of $160,979.47 for 1941, which was not attributable to the carrybacks.
The plaintiff filed a waiver under section 272 (d) on October 1, 1948, consenting to the assessment and collection of the deficiencies in tax and acceptance of the overassessments. The- deficiencies were assessed on November 25, 1949.
The Commissioner computed interest on the $160,979.47 income tax overpayment from December 15, 1942 (the date of' overpayment), to March 15, 1943 (the due date of the carryback return). The Commissioner also allowed interest on this overpayment, indirectly, from October 12, 1943, to October 31, 1948 (the thirtieth day after the filing of the waivers under section 272 (d)). The Commissioner also computed interest on another part of the overassessment that was credited against the deficiencies to the thirtieth day after the filing of the waiver rather than to the date of assessment *766of the deficiencies. The defendant concedes that interest on this latter sum should have been allowed to the date of the assessment of the deficiencies against which this sum was credited on November 25, 1949. See Abney Mills v. United States, 131 C. Cls. 159, and the cases therein cited; 1955-82 Int. Rev. Bull. 18, Rev. Rul. 55-485. The interest conceded to be due the plaintiff on this latter sum is $12,584.57.
The plaintiff seeks, in addition, interest on the $160,979.47 income tax overpayment due to general adjustments which was not attributable to carrybacks, from the date of overpayment to the date of assessment of the deficiencies against which this amount should have been credited, less interest already allowed. The additional interest sought is $15,-864.20. The failure of the Commissioner to allow this additional interest resulted from his netting the income tax overpayment due to general adjustments for 1941 against the income tax deficiencies attributable to the carrybacks to 1941, and from computing interest on the net, deficiencies. No statutory authority is cited for this procedure of netting and assessment of only the net amounts. Such a procedure is contrary to and frustrates the interest scheme provided in sections 2921 and 3771 2 of the Code.
*767Section 292 (a) provides that interest at the rate of six percent shall be paid on deficiencies from the date prescribed for the payment of the tax to the date the deficiency is assessed, or in the case of a waiver under section 272 (d), to the thirtieth day after the filing of the waiver or to the date the deficiency is assessed whichever is the earlier. Section 3771 (a) and (b) provide that interest at the rate of six percent shall be paid on overpayments from the date of overpayment to a date preceding the date of the refund check by not more than thirty days, or in case of a credit to the date of the assessment of the amount against which the credit is taken.
Sections 322 (a) (1) 3 and 3770 (a) (4) 4 set forth the crediting authority of the Commissioner with respect to this matter. We see no reason to depart from the statutory scheme of allowance of interest.
The defendant contends that the $160,979.47 income tax overpayment due to general adjustments was “extinguished” or “eliminated” by the carryback from 1942 which resulted in an income tax deficiency in the amount of $191,380.72, and that interest was properly terminated on the $160,979.47 on March 15,1943 (the effective date of the carryback). The defendant relies on Rodgers v. United States, 123 C. Cls. 779. The issue presented and decided in that case was whether the Government was entitled to interest on a deficiency that existed in 1944, which was not assessed because of a net operating loss carryback which resulted in an overpayment in the same year in a larger amount. In that case the Commissioner assessed only the net difference. That case was decided before the Virginia Electric and Power Co. v. United States, 130 C. Cls. 189, and Abney Mills v. United States, supra, cases, and the issue of when interest terminated under *768the statutes on the deficiency and overpayment was not before the court. The Rodgers case, supra, correctly held that interest was due the Government on the deficiency notwithstanding the fact' that the deficiency was not formally assessed because the Commissioner had netted the overpayment thereto for the same year. On the issue and the facts in that case we do not see how it can be said that the court was sanctioning as an established rule the netting procedure of the Commissioner and making an exception to the statutory provisions.
In addition to the conceded $12,584.57, the plaintiff is entitled to recover $15,864.20, which is the interest on the $160,979.47 to the assessment date of the deficiencies against which it should have been credited, November 25, 1949, less the interest already allowed, or a total of $28,448.97.
The plaintiff requests interest on this amount but makes no argument and cities no authority for the allowance of interest on interest. Accordingly no interest is allowed on the $28,448.97.
The plaintiff’s motion for summary judgment is granted and defendant’s motion for summary judgment is denied.
Judgment will be entered for plaintiff in the amount of $28,448.97.
It is so ordered.
