delivered the opinion of the Court.
This is a suit under Title VII of the Revenue Act of 1936, 49 Stat. 1648, 1747, 7 U. S. C. § 644 et seq., for a refund of processing taxes paid under the Agricultural Adjustment Act of 1933. The problem of the case derives from the procedural requirements of a claim for such a refund.
*294 The petitioner, Angelus Milling Company, known until June, 1933 as the Middleport Flour Mills, Inc., was a processor of wheat, with its principal office in Niagara Falls, New York. During the years for which the refund is claimed — 1933 to 1936 — its processing operations were closely connected with those of the Niagara Falls Milling Company. The two companies had the same officers, employees, and majority stockholder, and a joint bank account. They also had a common set of books, but the respective transactions of the two companies — purchases, costs of manufacture, sales — were entered in their separate accounts on the books. Between July 9, 1933, and January 31, 1935, the companies filed joint processing tax returns. Between February 1, 1935, and November 30, 1935, Niagara filed returns in its name on behalf of itself and petitioner.
After
United States
v.
Butler,
To review this disallowance, petitioner brought proceedings in the United States Processing Tax Board of Review. A motion to dismiss, because of a fatal defect in the claim, was denied by the Board, but the Commissioner in his answer stood on his ground that the Board was without jurisdiction to entertain the proceedings. At this stage in the litigation Congress abolished the Processing Tax Board of Review and transferred its jurisdiction to the present Tax Court. That Court granted the Commissioner’s renewed motion to dismiss,
Petitioner’s claim for recovering processing taxes paid by it was properly rejected by the Commissioner if it did
*296
not satisfy the conditions which Congress directly and through the rule-making power given to the Treasury laid down as a prerequisite for such refund. Insofar as Congress has made explicit statutory requirements, they must be observed and are beyond the dispensing power of Treasury officials.
Tucker
v.
Alexander,
Candor does not permit one to say that the power of the Commissioner to waive defects in claims for refund is. a subject made crystal-clear by the authorities. The question has been somewhat complicated by cases involving amendments of claim. Thus, in
United States
v.
Memphis Cotton Oil Co., supra,
a claimant’s amendment was allowed because filed before his original claim was rejected on formal grounds. According to what was there said, there can be no amendment after a Rejection though
*297
the Commissioner had examined the claimant’s books and tentatively found an overpayment. See
Edwards
v.
Malley,
Treasury Regulations are calculated to avoid dilatory, careless, and wasteful fiscal administration by barring incomplete or confusing claims. Tucker v. Alexander, supra, at 231; Commissioner v. Lane-Wells Co., supra, at 223-224. But Congress has given the Treasury this rule-making power for self-protection and not for self-imprisonment. If the Commissioner chooses not to stand on his own formal or detailed requirements, it would be making an empty abstraction, and not a practical safeguard, of a regulation to allow the Commissioner to invoke technical objections after he has investigated the merits of a claim and taken action upon it. Even tax administration does not as a matter of principle preclude considerations of fairness.
Since, however, the tight net which the Treasury Regulations fashion is for the protection of the revenue, courts should not unduly help disobedient refund claimants to slip through -it. The showing should be unmistakable that the Commissioner has in fact seen fit to dispense with his formal requirements and to examine the merits of the claim. It is not enough that in some roundabout way the facts supporting the claim may have reached him. The Commissioner’s attention should have been focused on the merits of the particular dispute. The evidence should be clear that the Commissioner understood the specific claim *298 that was made even though there was a departure from form in its submission. We do not think that the petitioner has made out such a case here.
The evidence of waiver largely rests upon a letter from a General Deputy Collector requesting an examination of certain books, and upon affidavits of two accountants, one an officer of the company, to the effect that the Commissioner examined petitioner’s books in order to consider the claim. We agree with the Tax Court that the evidence is insufficient to establish waiver. The letter from the General Deputy Collector requesting petitioner’s president to allow examination of the “records of the Middleport Elour Mills, Inc., and Angelus Flour Mills, Inc.” was in connection with the claim which had been filed by the Niagara Milling Company. In view of the confusing identity of interest of the two companies, it is not unreasonable to attribute this inquiry, as did the Tax Court, to Niagara’s claim and not to petitioner’s. For similar reasons, the affidavits regarding the purpose of the Commissioner’s representatives bear interpretation of a like significance.
In the
Memphis Cotton Oil
case, where an amendment was allowed out of time, the Deputy Commissioner, after an audit of the taxpayer’s books, notified the taxpayer in writing that its refund claims had been considered and that its taxes had been readjusted in accordance with a proven overassessment. Similar evidence of preoccupation by the Commissioner with the particular claim and controversy has been offered in cases where waiver was recognized. See,
e. g., United States
v.
Elgin Watch Co.,
An additional argument of the petitioner need not detain us long. It urges that taking the claims filed by Niagara and petitioner together, they furnish all the data required by the regulations. But it is not enough that somewhere under the Commissioner’s roof is the information which might enable him to pass on a claim for refund. The protection of the revenue authorizes the Commissioner to demand information in a particular form, and he is entitled to insist that the form be observed so as to advise him expeditiously and accurately of the true nature of the claim.
Affirmed.
Notes
Section 903 of Title VII of the 1936 Revenue Act, 49 Stat. 1648, 1747, requires that no refund be made or allowed “unless ... a claim for refund has been filed ... in accordance with regulations prescribed by the Commissioner with the approval of the Secretary. All evidence relied upon in support of such claim shall be clearly set forth under oath.”
The applicable regulations provide for the making of claims on prescribed forms, presentation of the grounds urged, and submission of evidence, etc. Treas. Reg. 96, Arts. 201, 202, 601, 603, 605, 606. The only information furnished in these claims is the name and address of the joint claimants, and a statement of the dates and amounts of the tax payments made by the Niagara Milling Company.
After we granted certiorari in this case, the same question of timeliness as to filing of the petition emerged as is raised in Commissioner v. Estate of Bedford, ante, p. 283. The decision in the Bedford case governs this.
