This is аn appeal from a judgment of the United States Tax Court,
I.
FACTS AND PROCEEDINGS BELOW
Tаxpayers Harry and Alice Karmun, who are natives of Alaska, filed federal income tax returns for 1977 and 1978 with the Internal Revenue Service Center in Ogden, Utah. For the same years, appellant Harry Karmun and his father, Alfred Karmun, filed partnership returns for their partnership named Alfred K. Karmun & Son (the partnership). The partnership operates a herd of аpproximately 2,000 reindeer under the provisions of the Reindeer Industry Act of 1937, 25 U.S.C. § 500 (1982) (the Reindeer Act or the Act). The reindeer were grazed on public land under grazing per *569 mits issued by the Secretary of the Interior pursuant to the Act. The income here in dispute was appellants’ distributive share of the partnership’s income, all of which was realized from thе sale of reindeer and reindeer products during 1977 and 1978.
The Reindeer Act was adopted in order to provide a “means of subsistence for the Eskimos and other natives of Alaska.” 25 U.S.C. § 500 (1982). To this end, the Act authorized the Secretary of the Interior to acquire for the Eskimos reindeer and other property owned by nonnatives. The Act further authorized the Sеcretary to distribute, or hold in trust, the reindeer and other property and to organize, manage, and regulate the reindeer industry in such a manner as to establish and maintain for such Alaska natives a self-sustaining business. Id.
On their joint federal income tax returns for 1977 and 1978, appellants did not include as income Harry Karmun’s distributive share of the partnership income for those years. On examination of those returns, the Commissioner determined that this share should have been included in gross income for each year, and accordingly, determinеd income tax deficiencies in the respective amounts of $1,931 and $8,688.83. Appellants thereafter filed a petition with the Tax Court seeking a redeter-mination of the assеrted deficiencies on the ground that the Reindeer Act exempts from taxation income derived from reindeer and reindeer products. The Tax Court rejected that contention. Therefore, the sole question on appeal is whether earnings received by Alaskan natives from the sale of reindeer and reindeer products arе exempt from federal income taxation under the Reindeer Act.
II.
DISCUSSION
Appellants make five arguments. First, they contend that, although the Reindeer Act does not expressly exempt from taxation income derived from reindeer and reindeer products, this court ought to imply an exemption on the basis of the purposes and policies of the Act. Second, they argue that, under section 500g of the Reindeer Act, reindeer and reindeer products are “restricted property” as that term is used in Indian law, and that, under the principles of
Squire v. Capoeman,
A. The Requirement of an Explicit Exemption
This circuit has long held that Indians are subject to federal income taxes, as are other citizens, unless an exemption from taxation can be found in the language of a Treaty or Act of Congress.
Hoptowit v. Commissioner,
No сlear expression of intent to exempt appears in the Reindeer Act. Appellants
*570
argue, nevertheless, that the Act taken as a whole suggests that Congress intended an exemption. In making this argument, appellants rely principally on
Stevens v. Commissioner,
Appellants misread
Stevens.
In
Stevens,
this court held that income derived from lands purchased under the Indian Reorganization Act of 1934 (the IRA) is exempt from federal inсome taxation. The court reasoned that although the IRA itself does not contain express exemptive language, it has to be construed
in pari materia
with the General Allotment Act of 1887 (the GAA), which does contain such clear language.
Stevens,
B. Squire v. Capoeman
In
Squire v. Capoeman,
Moreover, as the Tax Court observed, the purpose of the legislation involved here is entirely different from that in
Squire.
The purpose of the GAA was tо benefit the individual allottees by preparing them to become independent citizens. Accordingly, the
Squire
court found that the tax exemption was crucial to fulfilling this purposе.
Squire,
C. Other Arguments
Appellants’ third argument is that the contracts conveying the reindeer to them from the Government evince an intent to exemрt from taxation the income at issue here. These contracts were not introduced into evidence before the Tax Court, and are not part of the record оn appeal. Normally, an appellate court will not supplement the record on appeal with evidence not reviewed by the lower court.
Dickerson v. Alabama,
Appellants also seek to bolster their position by relying on an opinion issued by the Department of the Interior suggesting that income from the sale of reindeer is exempt from taxation. 2 Op.Sol. on Indian *571 Affairs 2016 (U.S.D.I. July 2, 1970). The opinion is not controlling. As the Interior opinion itself states, the authoritative determination of federal income tax quеstions is within the province of the Treasury, not the Interior, Department. Id. at 2017. To give great weight to the opinion in these circumstances would thus be inappropriate.
Finally, appellants argue that the IRS has conceded in Rev.Rul. 67-284, 1967-
For the foregoing reasons, we affirm the judgment of the Tax Court.
AFFIRMED.
