OPINION
Tannenwald, Chief Judge:Respondent has determined deficiencies in petitioners’ Federal income tax for the calendar years 1975 and 1976 in the respective amounts of $4,495 and $4,948.78. The sole issue for decision is whether petitioners are entitled to exclude from their gross income amounts received by Joseph T. Smith as overtime pay while employed by the U.S. Customs Service in the Bahamas.
All of the facts have been stipulated and are so found.
Petitioners are husband and wife who resided in Sunnyvale, Calif., at the time the petitions herein were filed. They timely filed their joint Federal income tax returns for 1975 and 1976 with the Internal Revenue Service Center in Philadelphia, Pa., and Fresno, Calif., respectively. Marie A. Smith is a party to this proceeding solely by virtue of having filed joint income tax returns with her husband; consequently, Joseph T. Smith will hereinafter'be referred to as petitioner.
Petitioner is a customs inspector (civil service employee) with the U.S. Customs Service (hereinafter referred to as customs). From September 7, 1974, through September 11, 1976, he was employed at a customs preclearance station in Nassau, Bahamas. The purpose of a preclearance station is to facilitate the customs clearance of passengers and baggage into the United States. The petitioner was physically present in the Bahamas for more than 510 days during 18 consecutive months of this period.
Frequently, airlines request the services of customs inspectors during their normal off-duty hours at preclearance stations to process passengers and baggage for flights departing directly for the United States (these services will hereinafter sometimes be referred to as overtime). In order for such a request to be granted, the airline must deposit money or post a bond sufficient to insure payment for the services provided. This requirement is mandated by statute. See 19 U.S.C. secs. 267, 1451 (1976). Section 267 of title 19 provides in pertinent part:
Sec. 267. Compensation for overtime services; fixing working hours
The Secretary of the Treasury shall fix a reasonable rate of extra compensation for overtime services of customs officers and employees. * * * The said extra compensation shall be paid by the master, owner, agent, or consignee of such vessel or other conveyance whenever such special license or permit for immediate lading or unlading or for lading or unlading at night or oh Sundays or holidays shall be granted to the appropriate customs officer, who shall pay the same to the several customs officers and employees entitled thereto according to the rates fixed therefor by the Secretary of the Treasury. * * *
Section 1451 of title 19 provides in pertinent part:
Sec. 1451. Extra compensation
Before any such special license to unlade shall be granted, the master, owner, or agent of such vessel or vehicle, or the person in charge of such vehicle, shall be required to deposit sufficient money to pay, or to give a bond in an amount to be fixed by the Secretary conditioned to pay, the compensation and expenses of the customs officers and employees assigned to duty in connection with such unlading at night or on Sunday or a holiday, in accordance with the provisions of section 267 of this title. * * * Upon a request made by the owner, master, or person in charge of a vessel or vehicle, or by or on behalf of a common carrier or by or on behalf of the owner or consignee of any merchandise or baggage, for overtime services of customs officers or employees at night or on a Sunday or holiday, the appropriate customs officer shall assign sufficient customs officers or employees if available * * * , but only if the person requesting such services deposits sufficient money to pay, or gives a bond in an amount to be fixed by * * * such customs officer, conditioned to pay the compensation and expenses of such customs officers and employees * * * . At ports of entry and customs stations * * * , between the United States and Canada or between the United States and Mexico, the appropriate customs officer, under such regulations as the Secretary of the Treasury may prescribe, shall assign customs officers and employees to duty at such times during the twenty-four hours of each day, including Sundays and holidays * * * ; but all compensation payable to such customs officers and employees shall be paid by the United States * * *
Upon completion of an overtime assignment, a customs inspector prepares a work ticket which identifies the employee, where and for whom the services were provided, a reference to account for money received as payment for the service, and a surety number of the insurer guaranteeing payment of the overtime charge. When customs receives the completed work ticket, it prepares a bill for the airline to secure payment for the overtime services.
A customs employee assigned to work overtime remains at all times an employee of the United States, under the sole control and supervision of customs. The airline has no authority to hire or fire a customs inspector, nor does it exercise any control over compensation or promotions given to an inspector. All amounts paid to customs employees, including overtime pay, are in the form of U.S. Government checks, issued by the Treasury Department. These checks are delivered by customs, which has the sole obligation to pay an inspector’s salary. Any credit risk for failure of an airline to repay the cost of overtime services of customs employees is borne by the U.S. Government.
During 1975, petitioner earned wages of $27,779.84, of which $12,282.80 represented overtime pay. In 1976, his wages were $26,864, of which $7,677 represented compensation for overtime services. Petitioner excluded from his gross income all amounts received as overtime pay for the years in issue.1 Respondent has determined that these amounts were improperly excluded from petitioners’ income.
The issues presented in this case are: (1) Whether petitioner’s overtime pay attributable to services performed while he resided in the Bahamas is excludable from his gross income pursuant to the general exclusion of section 911(a)(2)2 or whether it falls within the exception to that exclusion applicable to "amounts paid by the United States or any agency thereof’ (see sec. 911(a)(2));3 (2) if the overtime is not excluda-ble, whether section 911(a)(2), as it applies to petitioner, is unconstitutional.
Congress first excluded foreign earned income from Federal income tax in 1926 (see sec. 213(b)(14), Revenue Act of 1926, ch. 27, 44 Stat. (Part 2) 26), in order to promote foreign trade and to place U.S. citizens residing abroad on an equal footing with foreign workers (see H. Rept. 1, 69th Cong., 1st Sess. 7 (1925); 75 Cong. Rec. 10410-10411 (1932), reprinted in J. Seidman, Legislative History of Federal Income Tax Laws, 1938-1861, at 472-473 (1938)). However, Congress recognized by 1932 that a blanket exclusion for foreign earned income provided an unjustifiable windfall for U.S. Government employees stationed in foreign countries who frequently paid neither Federal income tax (bécause of the statutory exclusion) nor foreign income tax (because foreign nations often do not tax the compensation of U.S. Government employees). See S. Rept. 665, 72d Cong., 1st Sess. 31 (1932), 1939-1 C.B. (Part 2) 496, 518; 75 Cong. Rec. 10410, supra. With an eye towards military personnel stationed at foreign bases, ambassadors, and foreign service workers (see 75 Cong. Rec. 10410, supra), Congress excepted from the foreign earned income exclusion those amounts "paid by the United States or any agency thereof’ (see sec. 116(a), Revenue Act of 1932, Pub. L. 72-154, 47 Stat. 169), and that exception has remained a part of the Internal Revenue Code and forms the basis of the instant dispute.4.
Petitioner concedes — and there could be no serious arguments to the contrary — that his regular pay constitutes an amount paid by an agency of the U.S. Government within the meaning of the parenthetical exception contained in section 911(a)(2). Yet, petitioner argues that his overtime pay should be treated differently, even though it was for precisely the same types of services performed under precisely the same conditions as generated his regular compensation: petitioner was paid by U.S. Treasury check for customs preclearance, was at all times an employee of the United States, was under the direction and control of the United States, could be hired and fired only by customs, and could look only to the United States in case of nonpayment. The difference in treatment, so petitioner alleges, follows from the statutory requirement that an airline desiring petitioner’s overtime services must guarantee in advance that it will reimburse customs for petitioner’s overtime salary.5 See p. 1183 supra.
Petitioner cites Mooneyhan v. Commissioner, 47 T.C. 693 (1967), revd. 404 F.2d 522 (6th Cir. 1968), for the proposition that we should treat his overtime pay as "paid by” the airlines within the meaning of section 911(a)(2) because that section speaks to the source of a taxpayer’s salary rather than to his employer. See also Wolfe v. Commissioner, 43 T.C. 572 (1965), revd. 361 F.2d 62 (D.C. Cir. 1966); Krichbaum v. United States, 138 F. Supp. 515 (E.D. Tenn. 1956). Petitioner also relies upon an inference which he claims can be drawn from Erlandson v. Commissioner, 277 F.2d 70 (9th Cir. 1960), affg. a Memorandum Opinion of this Court, where funds were treated as paid by U.S. Government agencies even though the agencies were not the taxpayer’s nominal employers. See also Teskey v. Commissioner, 30 T.C. 456 (1958).
While it is true that the application of section 911(a) does not necessarily turn on an employer/employee relationship (see Dowd v. Commissioner, 37 T.C. 399, 406 (1961); Sverdrup v. Commissioner, 14 T.C. 859, 865 (1950)), it is also true that when there is such a relationship, one’s salary usually comes from one’s employer and the existence of such a relationship is a significant factor. See United States v. Johnson, 386 F.2d 824 (5th Cir. 1967); Erlandson v. Commissioner, supra at 72. When we have looked through a third-party payor to see the U.S. Government as the true source of funds, we have done so when the third party was a disbursing agent of the United States. See Erlandson v. Commissioner, supra; Dowd v. Commissioner, supra; Teskey v. Commissioner, supra.
We have held that employees of the Bureau of Public Roads of the U.S. Department of Commerce may exclude their salaries pursuant to section 911(a) because their U.S. Treasury pay checks were "paid” with funds deposited by Iran (see Mooneyhan v. Commissioner, supra; Wolfe v. Commissioner, supra), although other courts have almost uniformly disagreed. Commissioner v. Mooneyhan, 404 F.2d 522 (6th Cir. 1968), revg. 47 T.C. 693 (1967); United States v. Johnson, supra; Commissioner v. Wolfe, 361 F.2d 62 (D.C. Cir. 1966), revg. 43 T.C. 572 (1965); Johnson v. United States, 182 Ct. Cl. 593, 390 F.2d 715 (1968).6
In the instant case, petitioner was at all times performing U.S. Customs inspection for the U.S. Government. That is an intrinsically governmental function (see 19 U.S.C. sec. 6 (1976)), performed exclusively under Government auspices (see 18 U.S.C. sec. 209(a) (1976)). Cf. United States v. Myers, 320 U.S. 561, 567 (1944). In the very real sense, it can be said that petitioner occupies a different position from the taxpayers in Mooneyhan, Wolfe, and the two Johnson cases; in those cases, although the services were being performed by the taxpayers as employees of the U.S. Government, they were being rendered to a foreign government. In this context, the instant case can be distinguished. Nevertheless, we recognize that the thrust of the cases referred to, and, in particular, those in Mooneyhan and Wolfe, where we were reversed, is that the ultimate "source of funds” is not the controlling factor. We now agree with that view, and so to the extent that our opinions in Mooneyhan and Wolfe are inconsistent with that thrust, we will no longer follow them.
Petitioner’s job is performed for the United States and as a U.S. employee. Indeed, officers of the customs service are attached to the foreign service through the Department of State (see 19 U.S.C. sec. 6, supra), and thus they are members of the precise class which Congress sought to address in the statutory exception to section 911(a)(2). See 75 Cong. Rec. 10410, supra. Petitioner, therefore, falls within the category of persons excluded from the benefit of section 911(a)(2). That Congress chooses to seek reimbursement from those who benefit from overtime services does not justify a different conclusion. Cf. Erlandson v. Commissioner, supra at 73.
Petitioner’s second argument is that, if the parenthetical exception to section 911(a)(2) applies to his overtime compensation, then that section violates his constitutional right to equal protection implicit in the due process clause of the Fifth Amendment.7 See Bolling v. Sharpe, 347 U.S. 497 (1954). This argument utterly lacks merit.
A Federal income tax is only limited by the due process clause of the Fifth Amendment in those "rare and special instances” which represent "extreme and glaring” exercises of legislative discretion "fairly outside the zone of possible debate.” See A. Magnano Co. v. Hamilton, 292 U.S. 40, 44 (1934); Cohan v. Commissioner, 39 F.2d 540, 545 (2d Cir. 1930). In the absence of a suspect classification (see Moritz v. Commissioner, 469 F.2d 466 (10th Cir. 1972), revg. 55 T.C. 113 (1970)), or a substantial impediment of a fundamental right (see Johnson v. United States, 422 F. Supp. 958 (N.D. Ind. 1976), affd. sub nom. Barter v. United States, 550 F.2d 1239 (7th Cir. 1977) (per curiam); Bryant v. Commissioner, 72 T.C. 757, 765 (1979)), no violation of equal protection is present in a Federal income tax statute so long as there is a conceivably reasonable basis for its classification (Keller v. Commissioner, 70 T.C. 279, 284-285 (1978); see Personnel Admr. v. Feeney, 442 U.S. 256, 271-273 (1979)). See generally 1 J. Mertens, Law of Federal Income Taxation, sec. 4.09 (1974).
The reasons behind section 911(a) and its exceptions (see pp. 1184-1185 supra) are plainly rational and the statute reasonably effectuates them. Accordingly, we hold that section 911(a)(2) is constitutional.
In view of the foregoing, petitioner, may not exclude his overtime pay under section 911(a)(2).
Decisions will be entered for the respondent.
Reviewed by the Court.
Nims, J., dissents.Due to an Internal Revenue Service error, the amount of exempt earned income was raised from $7,677 to $13,826, resulting in a refund for petitioners in 1976 of $3,630.78.
A11 section references are to the Internal Revenue Code of 1954 as amended and in effect during the years in issue.
Respondent concedes that petitioner has satisfied all other prerequisites to exclusion imposed by sec. 911. On the other hand, petitioner concedes that customs is an agency of the U.S. Government within the meaning of sec. 911(aX2).
tee also Krichbaum v. United States, 138 F. Supp. 515 (E.D. Tenn. 1956), for a more detailed review of the pertinent legislative history.
The parties agree, however, that the U.S. Customs Service had the "primary and sole obligation to pay” the petitioner and that the U.S. Government "assumes the credit risk that the private party might not repay the cost of overtime services of Customs employees.” Thus, petitioner could not seek payment from the airlines or their bonding agencies
But see Krichbaum v. United States, supra, decided prior to any of the cases cited in the text (employees of Bureau of Public Roads doing construction in Ethiopia may exclude pay under sec. 911(a)(2)).
Petitioner mistakenly based his constitutional argument on the equal protection clause of the 14th Amendment, although that amendment is by its own terms only applicable to the States. We have recast petitioner’s argument in proper constitutional garb.
