PHILLIPS, Circuit Judge.

During 1958 National Cash Register Company, a Maryland corporation with its principal place of business in Dayton, Ohio, owned all of the voting stock of two subsidiary corporations, The National Cash Register Company Limited (NCR Ltd.) and The National Cash Register (Manufacturing) Limited (NCR Mfg.). Both of the subsidiaries were organized under the laws of and were operated in the United Kingdom.

The issue in this case is whether, with respect to standard tax paid by a United Kingdom subsidiary, a United States corporation which received dividends in 1958 from a wholly owned United Kingdom subsidiary is entitled to a foreign tax credit under both § 902 of the Internal Revenue Code and Article XIII(1) of the United States-United Kingdom Income Tax Convention of 1945, as amended. The District Court held that the taxpayer corporation was entitled to take a credit for the standard tax under both § 902 and the Tax Convention and entered judgment in favor of the taxpayer and against the Government for a refund of $508,643.65 plus interest of $96,263.84. The Government appeals, contending that provisions of § 902 and Article XIII(1) are mutually exclusive and that the taxpayer is not entitled to a credit under both with respect to the standard tax.

The British Dividend Tax

In order to answer the question presented it is necessary to understand some of the principles of British taxation of corporate dividends. The two subsidiary corporations were subject to the United Kingdom standard tax, an income tax imposed at the flat rate of 38.75 per cent. As British corporations, both subsidiaries were also subject to a profits tax levied at the rate of ten per cent. The standard tax applies both to individuals and to corporations. The profits tax applies only to corporations. Neither tax is deductible in computing the other.

In 1958 both subsidiaries paid dividends "free of standard tax" to the parent corporation. In the United Kingdom a corporate dividend may be declared either "free of standard tax" or "with deduction of standard tax." These United Kingdom tax concepts have no parallel in the tax treatment of dividends by the United States.

A British corporation pays dividends out of profits from which standard tax and profits tax already have been deducted. When a dividend is declared "free of standard tax," it means (1) that the declared amount of the dividend is actually paid to the shareholder and (2) that the dividend is not subject to any additional United Kingdom tax after it has been paid to the shareholder. When the shareholder is reporting his income, however, he is required to include the amount of the dividend actually received plus an amount representing the proportional share of the standard tax that the corporation has paid on the earnings from which the dividend was distributed. In British tax nomenclature the phrase "standard tax appropriate to the dividend" refers to the pro rata share of the standard tax which the corporation has paid on the earnings from which the dividend was paid. A corporation is treated as a conduit composed of its shareholders. Although the shareholder reports the dividend actually received plus the standard tax appropriate to the dividend, the shareholder is not subject to any tax on the dividend. "The scheme of the British legislation is to impose on corporate earnings only one standard tax, at the source, and to avoid the `double' taxation of the corporate income as it passes to the hands of its stockholders, * * *." Biddle v. Commissioner of Internal Revenue, supra, 302 U.S. 573, 579, 58 S.Ct. 379, 382.

The Tax Convention

Because of the decision in Biddle v. Commissioner of Internal Revenue, supra, 302 U.S. 573, 58 S.Ct. 379, a special treaty provision was deemed necessary to afford United States stockholders a foreign tax credit for the standard tax appropriate to the dividend received from a United Kingdom corporation. In Biddle the Supreme Court held that for purposes of United States taxation the standard tax appropriate to the dividend was a tax imposed on the British corporation, not a tax imposed on the recipient of the dividend. Having characterized the standard tax as a tax imposed upon and collected from the corporation, the Court found that a shareholder was not warranted in taking a credit for a tax which he did not pay.

Article XIII(1) of the Tax Convention provides that if the shareholder in the United States receiving a dividend paid by a British corporation elects to include in his gross income the amount of the standard tax appropriate to the dividend, the recipient will be deemed to have paid the standard tax appropriate to the dividend. Accordingly, the shareholder who complies with the inclusion requirement of Article XIII(1) is allowed a direct credit against his United States tax for the amount of the standard tax appropriate to the dividend. It is to be emphasized that the foreign tax credit provided by Article XIII(1) is limited to the standard tax appropriate to the dividend. No credit is available under Article XIII (1) for the standard tax which is allocable to the portion of the corporate earnings which are not distributed as dividends. Nor does Article XIII(1) offer a foreign tax credit for other United Kingdom taxes, such as the profits tax.

Section 902, Internal Revenue Code

Section 902 permits a domestic corporation owning at least ten per cent of the voting stock of a foreign corporation from which it receives dividends in any taxable year to take a credit for a fractional portion of the taxes paid by the foreign corporation. Unlike Article XIII(1), which limits the credit to the standard tax paid by the corporation, § 902 provides a credit for "any income, war profits or excess profits taxes" paid by the foreign corporation. In American Chicle Co. v. United States, 316 U.S. 450, 62 S.Ct. 1144, 86 L.Ed. 1591, the Supreme Court established the formula for the § 902 credit for taxes deemed to have been paid on profits distributed as dividends. The numerator is the dividends received by the parent corporation. The denominator is the accumulated profits of the foreign subsidiary corporation. The multiplicand is the taxes paid upon or with respect to the accumulated profits of the foreign corporation; i.e., "so much of the taxes as is properly attributed to the accumulated profits, or the same proportion of the total taxes which the accumulated profits bear to the total profits." 316 U.S. at 452, 62 S.Ct. at 1145.

It is important to note that § 902 limits the credit for foreign taxes to that proportion of the tax which the dividend received by the domestic corporation bears to the total profits of the foreign corporation. Although the foreign corporation may have paid foreign taxes in a given year, under § 902 the domestic corporation is not entitled to any credit for those foreign corporation taxes for a year in which it receives no dividends from the foreign corporation. Abbot Laboratories International Co. v. United States, 160 F. Supp. 321, 328 (N.D.Ill.), aff'd per curiam, 267 F.2d 940 (7th Cir.).

The Claim for Double Credits

Coming now to the factual details of the present case, the two subsidiaries during 1958 had total profits before payment of taxes and accumulated (after tax) profits as follows:

Total Accumulated profits profits _____________ ______________ NCR Ltd. $2,409,564.52 $1,235,244.93 NCR Mfg. 3,927,833.75 1,886,861.66 _____________ ______________ Total: $6,337,398.27 $3,122,106.59

The 1958 taxes paid by the subsidiaries were as follows: United Kingdom Miscellaneous

Standard Profits Foreign Income Total Tax Tax Taxes Tax _____________ ___________ _________ _____________ NCR Ltd. $ 961,654.96 $207,583.57 $5,081.06 $1,174,319.59 NCR Mfg. 1,705,578.99 335,393.10 2,040,972.09 _____________ ___________ _________ _____________ Total: $2,667,233.95 $542,976.67 $5,081.06 $3,215,291.68

Out of the accumulated profits remaining after payment of the foregoing taxes, the two subsidiaries paid certain dividends to the taxpayer. The taxpayer also received certain other income from NCR Mfg. These amounts were as follows:

Dividends Accumulated declared and Other profits received income _____________ _____________ _____________ NCR Ltd. $1,235,244.93 $1,019,190.01 NCR Mfg. 1,886,861.66 1,571,981.25 $1,693,857.13 _____________ _____________ _____________ Total: $3,122,106.59 $2,591,171.26 $1,693,857.13

The dividends received by the taxpayer were declared "free of standard tax."

The District Court allowed the taxpayer's computation which (1) took a direct credit under Article XIII(1) for the standard tax appropriate to the dividend plus (2) an indirect credit under § 902 for the remaining standard tax which was allocable either to earnings which were retained after the payment of dividends or to earnings which were used to pay United Kingdom profits tax. In determining whether a credit for standard tax appropriate to the dividend may be taken under Article XIII(1) and another credit taken under § 902 for the remaining standard tax, we are faced with a situation in which neither the express language nor the published history of the Code or the Tax Convention provides definitive guidance.

The taxpayer contends that Article XIII(1) treats the standard tax appropriate to the dividend as a withholding tax and that under Biddle the remaining standard tax must be treated as a corporate income tax paid by the British subsidiary corporations. Following this reasoning, the District Court said: "Article XIII does not say or imply that only a part of the United Kingdom tax should be allowed as a credit and the Court can find no reason for doing so." We cannot agree.

The purpose of the Code and of the Convention is to avoid the incidence of double taxation by different nations of the same dividends. The avowed purpose of the Tax Convention is the "avoidance of double taxation and the prevention of fiscal evasion." Explaining the purpose of the statutory predecessor of § 902, the Supreme Court said:

"If, as is admitted, the purpose is to avoid double taxation, the statute, as written, accomplishes that result. The parent receives dividends. Such dividends, not its subsidiary's profits, constitute its income to be returned for [United States] taxation." American Chicle Co. v. United States, supra, 316 U.S. 450, 452, 62 S.Ct. 1144, 1145.

By limiting its credit to the standard tax appropriate to the dividend, Article XIII(1) does not permit any credit for standard tax which is not allocable to earnings distributed as dividends. Section 902 allows a credit only for foreign taxes on the portion of the foreign corporation's earnings which are distributed as dividends to a domestic corporation.

Having availed itself of the Article XIII(1) credit for the standard tax appropriate to the dividend, the taxpayer's use of a § 902 credit for the remaining standard tax results in a credit for foreign taxes allocable to earnings which were not distributed as dividends. A domestic corporation is not taxed on the entire earnings of a foreign corporation in which it owns stock unless the foreign corporation distributes all of its earnings as dividends to the domestic corporation. In the present case the two foreign subsidiaries retained a portion of their earnings. Because the United States taxes only the dividends paid by foreign corporations, there is no danger of international double taxation with respect to the earnings which the foreign corporation retains. In order to effectuate the purpose of the Code and the Convention, the taxpayer must elect either Article XIII(1) or § 902 of the Internal Revenue Code for computing its foreign tax credit with respect to the United Kingdom standard tax appropriate to the dividend.

Conclusion

We conclude that the District Court erred in ordering a refund of taxes based upon the taxpayers use of Article XIII(1) of the Convention and § 902 of the Code in combination. To allow resort to both the Convention and the statute would be to permit credits for standard taxes in excess of that which Congress, in enacting § 902, deemed necessary to alleviate the burden of international double taxation.

As said by this Court speaking through Judge Simons in Gentsch v. Goodyear Tire Rubber Co., 151 F.2d 997, 1000:

"We think, therefore, that the controlling principle of statutory construction is not that which requires special tax exemptions to be strictly construed, but rather the principle so often announced as not to require citation, that statutes must be so construed as to give effect of their general purpose and to implement the policy of the Congress. Relief from double taxation is not so much an act of grace as one of justice in determining the true net income of the taxpayer."

We hold that § 902 affords no credit for standard taxes in combination with Article XIII(1) and that the statute and convention are mutually exclusive. "Our interpretation affords every benefit negotiated for by the parties to the Convention on behalf of their respective residents and prevents an unintended tax windfall * * *" to the taxpayers in the present case. Maximov v. United States, 373 U.S. 49, 56, 83 S.Ct. 1054, 1058, 10 L.Ed.2d 184.

The judgment of the District Court is reversed and the case remanded for further proceedings not inconsistent with this opinion.
