¶1with whom Justice Scalia joins, concurring in the judgment.
¶2Today the Court announces that there is “no one test,” ante, at 175, to determine whether a home office constitutes a taxpayer’s “principal place of business” within the meaning of 26 U. S. C. § 280A(c)(l)(A), and concludes that whether a taxpayer will be entitled to a home office deduction will be “dependent upon the particular facts of each case,” ante, at 175. The Court sets out two “primary considerations,” ibid., to guide the analysis — the importance of the functions performed at each business location and the time spent at each location. I think this inquiry, “subtle” though it may be, ibid., will unnecessarily require the lower courts to conduct full-blown evidentiary hearings each time the Commissioner challenges a deduction under § 280A(e)(l)(A). Moreover, as structured, the Court’s “test” fails to provide clear guidance as to how the two-factor inquiry should proceed. Specifically, it is unclear whether the time element and importance-of-the-functions element are of equal significance. I write separately because I believe that in the overwhelming majority of cases (including the one before us), the “focal point” test — which emphasizes the place where the taxpayer renders the services for which he is paid or sells his goods — provides a clear, reliable method for determining whether a taxpayer’s home office is his “principal place of business.” I would employ the totality-of-the-circumstances inquiry, guided by the two factors discussed by the Court, only in the small minority of cases where the home office is one of several locations where goods or services are delivered, and thus also one of the multiple locations where income is generated.
¶3*181I certainly agree that the word “principal” connotes “ ‘most important,’ ” ante, at 174, but I do not agree that this definition requires courts in every case to resort to a totality-of-the-circumstances analysis when determining whether the taxpayer is entitled to a home office deduction under §280A(c)(l)(A). Rather, I think it is logical to assume that the single location where the taxpayer’s business income is generated — i. e., where he provides goods or services to clients or customers — will be his principal place of business. This focal point standard was first enunciated in Baie v. Commissioner, 74 T. C. 105 (1980),
¶4Indeed, if one were to glance quickly through the Court’s opinion today, one might think the Court was in fact adopting the focal point test. At two points in its opinion the Court hails the usefulness of the focal point inquiry: It states that the place where goods are delivered or services rendered must be given “great weight in determining the place where the most important functions are performed,” ante, at 175, and that “the point where services are rendered or goods delivered is a principal consideration in most cases,” ante, at 176. In fact, the Court’s discomfort with the focal point test seems to rest on two fallacies — or perhaps one fallacy and a terminological obstinacy. First, the Court rejects the focal point test because “no one test is determinative in every case.” *182Ante, at 175. But the focal point test, as I interpret it, is not always determinative: Where it provides no single principal place of business, the “totality of the circumstances” approach is invoked. Second, the Court rejects the focal point test because its name has a “metaphorical quality that can be misleading.” Ibid.But rechristening it the “place of sale or service test” — or whatever label the Court would find less confusing — is surely a simple matter.
¶5The Commissioner’s quarrel with the focal point test is that “it ignores management functions.” Tr. of Oral Arg. 24.
¶6*183There will, of course, be the extraordinary cases where the focal point inquiry will provide no answer. One example is the sole proprietor who buys jewelry wholesale through a home office, and sells it both at various craft shows and through mail orders out of his home office. In that case, the focal point test would yield more than one location where income is generated, including the home. Where the taxpayer’s business involves multiple points of sale, a court would need to fall back on a totality-of-the-circumstances analysis. That inquiry would be rationally guided, of course, by the two factors set out in the Court’s opinion: an analysis of the relative importance of the functions performed at each business location and the time spent at each. The error of the Tax Court’s original construction of the focal point test was the implicit view that the test allowed no es-. cape valve. Clearly it must. Nevertheless, since in the vast majority of cases the focal point inquiry will provide a quick, objective, and reliable method of ascertaining a taxpayer’s “principal place of business,” I think the Court errs today in not unequivocally adopting it.
¶7The difficulty with the Court’s two-part test can be seen in its application to the facts of this case. It is uncontested that the taxpayer is paid to provide one service — anesthesiology. It is also undisputed that he performs this service at several different hospitals. At this juncture, under the focal point test, a lower court’s inquiry would be complete: On these facts, the taxpayer’s home office would not qualify for the § 280A(c)(l)(A) deduction. Yet under the Court’s formulation, the lower court’s inquiry has only just begun. It would need to hear evidence regarding the types of business activities performed at the home office and the relative amount of time the taxpayer spends there. It just so happens that in this case the taxpayer spent 30 to 35 hours per week at the hospitals where he worked. But how would a court answer the §280A(c)(l)(A) question under the standard announced today if the facts were altered slightly, so that *184the taxpayer spent 30 to 35 hours at his home office and only 10 hours actually performing the service of anesthesiology at the various hospitals? Which factor would take precedence? The importance of the activities undertaken at the home compared to those at the hospitals? The number of hours spent at each location? I am at a loss, and I am afraid the taxpayer, his attorney, and a lower court would be as well.
¶8We granted certiorari to clarify a recurring question of tax law that has been the subject of considerable disagreement. Unfortunately, this issue is no clearer today than it was before we granted certiorari. I therefore concur only in the Court’s judgment.
¶9 In Baie, the taxpayer operated a hot dog stand. She prepared all the food in the kitchen at her home and transferred it daily to the stand for sale. She also used another room in her house exclusively for the stand’s bookkeeping. The Tax Court denied the taxpayer a home office deduction under § 280A(c)(l)(A), recognizing that although “preliminary preparation may have been beneficial to the efficient operation of petitioner’s business, both the final packaging for consumption and sales occurred on the premises of the [hot dog stand].” 74 T. C., at 109-110. Thus, the court concluded that the hot dog stand was the “focal point of [the taxpayer’s] activities.” Id., at 109.
¶10 The Commissioner’s position is not entirely consistent. At one point in his brief he seems to advocate adopting the focal point test: “Since a ‘business’ under the Code must be an activity designed to produce income, the principal place of a ‘business’ should ordinarily refer to the principal place where income is earned. The ‘focal point’ test previously applied by the Tax Court properly encapsulates that principle.” Brief for Petitioner 26, n. 17. At other points in his brief, however, the Commissioner appears to advocate the very test adopted by the Court. See id., at 18, 23-24.
¶11dissenting.
¶12Respondent is self-employed. He pays the ordinary and necessary expenses · Case Law">ordinary and necessary expenses associated with the operation of his office in McLean, Virginia; it is the only place of business that he maintains. In my opinion the Tax Court and the Court of Appeals correctly concluded that respondent is entitled to an income tax deduction for the cost of maintaining that office. This Court’s contrary conclusion misreads the term “principal place of business” in §280A of the Internal Revenue Code,
¶13I
¶14This case involves an exception to the general rule that “ordinary and necessary” business expenses are deductible.
¶15Deductions, as Justice Blackmun notes, ante, at 179, are a matter of legislative grace, but that is no reason to read into them unnecessary restrictions that result in the unequal treatment of similarly situated taxpayers. Such unfair treatment could, of course, have been required by the Tax Code, if Congress had wanted, for example, to discourage parents from working at home; to promote the construction of office buildings or separate structures on residential real estate; or to encourage hospitals to keep doctors near their patients. We have no reason to think that Congress intended any such results.
¶16II
¶17Before 1976, home office deductions were allowed whenever the use of the office was “appropriate and helpful” to the taxpayer.
¶18The most stringent conditions in §280A, enacted to prevent abuse by those who wanted to deduct purely residential costs, apply to deductions claimed by employees.
¶19Self-employed persons, such as respondent, must satisfy three conditions. Each is more strict and more definite than the “appropriate and helpful” standard that Congress rejected.
¶20First, a portion of the- dwelling unit must be used “exclusively” for a business purpose. The Commissioner’s proposed regulations construe the exclusive use requirement with appropriate strictness. They state that a portion of a dwelling unit is used exclusively “only if there is no use of that portion of the unit at any time during the taxable year other than for business purposes.”
¶21Second, the portion of the dwelling unit that is set aside for exclusive business use must be so “used on a regular basis.” Although this condition is not as specific as the “exclusive use” requirement, it obviously requires that the use *189be substantial. In- this case respondent spent two or three hours a day in his office communicating with surgeons, patients, insurance companies, and hospitals; doing his bookkeeping; handling his correspondence; and preparing himself for his professional assignments at other locations. He received business calls on his office answering machine and, of course, his business mail was addressed to that office. Again, because these uses occurred on a regular basis, it is undisputed that respondent has satisfied this requirement.
¶22Third, the use of the space must be as a “place of business” satisfying one of three alternative requirements. It must be used as:
“(A) the principal place of business for any trade or business of the taxpayer[,]
“(B) as a place of business which is used by patients, clients, or customers in meeting or dealing with the taxpayer in the normal course of his trade or business, or “(C) in the case of a separate structure which is not attached to the dwelling unit, in connection with the taxpayer’s trade or business.” 26 U. S. C. §280A(c)(l) (emphasis added).
¶23Subsection (C) is obviously irrelevant in this case, as is subsection (B). The office itself is not a separate structure, and respondent does not meet his patients there. Each of the three alternatives, however, has individual significance, and it is clear that subsection (A) was included to describe places where the taxpayer does not normally meet with patients, clients, or customers. Nevertheless, the Court suggests that Soliman’s failure to meet patients in his home office supports its holding.
¶24The meaning of “principal place of business” may not be absolutely clear, but it is absolutely clear that a taxpayer may deduct costs associated with his home office if it is his principal place of business or if it is a place of business used by patients in the normal course of his business or if it is located in a separate structure used in connection with his business. A home office could, of course, satisfy all three requirements, but to suggest that it need always satisfy subsection (B), or even that whether it satisfies (B) has anything to do with whether it satisfies (A), encourages the misapplication of a relatively simple provision of the Revenue Code.
¶25By conflating subsections (A) and (B) the Court makes the same mistake the Courts of Appeals refused to make when they rejected the Tax Court’s “focal point” test, which proved both unworkable and unfaithful to the statute.
¶26The principal office of a self-employed person’s business would seem to me to be the most typical example of a “principal place of business.” It is, indeed, the precise example used in the Commissioner’s proposed regulations of deductible home offices for taxpayers like respondent, who have no office space at the “focal point” of their work.
¶27The Court suggests that Congress would have used the term “ ‘principal office’ ” if it had intended to describe a home office like respondent’s. Ante, at 174. It is probable, however, that Congress did not select the narrower term because it did not want to exclude some business uses of dwelling units that should qualify for the deduction even though they *192are not offices. Because some examples that do not constitute offices come readily to mind — an artist’s studio, or a cabinetmaker’s basement — it is easy to understand why Congress did not limit this category that narrowly.
¶28The test applied by the Tax Court, and adopted by the Court of Appeals, is both true to the statute and practically incapable of abuse. In addition to the requirements of exclusive and regular use, those courts would require that the taxpayer’s home office be essential to his business and be the only office space available to him. 935 F. 2d 52, 54 (CA4 1991); 94 T. C., at 29. Respondent’s home office is the only place where he can perform the administrative functions essential to his business. Because he is not employed by the hospitals where he works, and because none of those hospitals offers him an office, respondent must pay all the costs necessary for him to have any office at all. In my judgment, a principal place of business is a place maintained by or (in the rare case) for the business. As I would construe the statute in this context, respondent’s office is not just the “principal” place of his trade or business; it is the only place of his trade or business.
¶29Nothing in the history of this statute provides an acceptable explanation for disallowing a deduction for the expense of maintaining an office that is used exclusively for business purposes, that is regularly so used, and that is the only place available to the taxpayer for the management of his business. A self-employed person’s efficient use of his or her resources should be encouraged by sound tax policy. When it is clear that no risk of the kind of abuse that led to the enactment of § 280A is present, and when the taxpayer has satisfied a reasonable, even a strict, construction of each of the condi*193tions set forth in § 280A, a deduction should be allowed for the ordinary cost of maintaining his home office.
¶30In my judgment, the Court’s contrary conclusion in this case will breed uncertainty in the law,
¶31I respectfully dissent.
¶32 Section 601 of the Tax Reform Act of 1976, 90 Stat. 1520, 1569-1572, as amended, 26 U. S. C. § 280A, provides, in part:
“(a) General Rule
“Except as otherwise provided in this section, in the case of a taxpayer who is an individual ... , no deduction otherwise allowable under this chapter, shall be allowed with respect to the use of a dwelling unit which is used by the taxpayer during the taxable year as a residence.
“(c) Exceptions for certain business or rental use; limitation on deductions for such use
“(1) Certain business use
“Subsection (a) shall not apply to any item to the extent such item is allocable to a portion of the dwelling unit which is exclusively used on a regular basis—
*185“(A) [as] the principal place of business for any trade or business of the taxpayer[,]
“(B) as a place of business which is used by patients, clients, or customers in meeting or dealing with the taxpayer in the normal course of his trade or business, or
“(C) in the case of a separate structure which is not attached to the dwelling unit, in connection with the taxpayer’s trade or business.
“In the case of an employee, the preceding sentence shall apply only if the exclusive use referred to in the preceding sentence is for the convenience of his employer.”
¶33 Section 162(a) of the Code provides, in part:
“There shall be allowed as a deduction all the ordinary and necessary expenses paid or incurred diming the taxable year in carrying on any trade or business, including . .. rentals or other payments required to be made as a condition to the continued use or possession, for purposes of the trade or business, of property ....”
¶34 As the Tax Court wrote, “Section 280A was not enacted to compel a taxpayer to rent office space rather than work out of his own home.” 94 T. C. 20, 29 (1990).
¶35See Commissioner v. Tellier, 383 U. S. 687, 689 (1966); Newi v. Commissioner, 432 F. 2d 998 (CA2 1970).
¶36 See, e. g., S. Rep. No. 94-938, pt. 1, p. 147 (1976):
“With respect to the ‘appropriate and helpful’ standard employed in the court decisions, the determination of the allowance of a deduction for these expenses is necessarily a subjective determination. In the absence of definitive controlling standards, the ‘appropriate and helpful’ test increases the inherent administrative problems because both business and personal uses of the residence are involved and substantiation of the time used for each of these activities is clearly a subjective determination. In many cases the application of the appropriate and helpful test would appear to result in treating personal living, and family expenses which are directly attributable to the home (and therefore not deductible) as ordinary and necessary business expenses, even though those expenses did not result in additional or incremental costs incurred as a result of the business use of the home.”
¶37 Congress may have been particularly offended by the home office deductions claimed by employees of the Internal Revenue Service. See Bodzin v. Commissioner, 60 T. C. 820 (1973), rev’d, 509 F. 2d 679 (CA4), cert. denied, 423 U. S. 825 (1975); Sharon v. Commissioner, 66 T. C. 515 (1976), aff’d, 591 F. 2d 1273 (CA9 1978), cert. denied, 442 U. S. 941 (1979). The Senate Report also used a common example of potential abuse:
“For example, if a university professor, who is provided an office by his employer, uses a den or some other room in his residence for the purpose of grading papers, preparing examinations or preparing classroom notes, an allocable portion of certain expenses . . . were incurred in order to perform these activities.” S. Rep. No. 94-938, pt. 1, at 147.
¶38 In addition to the conditions applicable to self-employed taxpayers, an employee must demonstrate that his office is maintained “for the convenience of his employer.” See 26 U. S. C. §280A(c)(l).
¶39 “With respect to the maintenance of an office in an employee’s home, the position of the Internal Revenue Service is that the office must be required by the employer as a condition of employment and regularly used for the performance of the employee’s duties....
“Certain courts have held that a more liberal standard than that applied by the Internal Revenue Service is appropriate. Under these decisions, the expenses attributable to an office maintained in an employee’s residence are deductible if the maintenance of the office is ‘appropriate and helpful’ to the employee’s business.” S. Rep. No. 94-938, pt. 1, at 144-145 (citations omitted); see also n. 6, supra.

¶41 The Court fails to appreciate the significance of the exclusive use requirement when it criticizes the Court of Appeals’ holding as “not far removed” from the test that led to the adoption of § 280A. See ante, at 174.
¶42 See ante, at 176: “That Congress allowed the deduction where those visits occur in the normal course even when some other location is the principal place of business indicates their importance in determining the nature and functions of any enterprise.”

¶44 The proposed regulations stated that “if an outside salesperson has no office space except at home and spends a substantial amount of time on paperwork at home, the office in the home may qualify as the salesperson’s principal place of business.” 45 Fed. Reg. 52403 (1980), 48 Fed. Reg. 33324 (1983).
¶45 For example, in Texas v. New Jersey, 379 U. S. 674, 680 (1965), we used the terms “main office” and “principal place of business” interchangeably. I recognize that there is disagreement over the proper interpretation of the term in 28 U. S. C. § 1332(c)(1), with some courts regarding the home office as the principal place of business and others regarding it as the place where the principal operations of the corporation are conducted. Under either view, however, the relevant place is one where the corporation owns or rents the premises; it is not a place owned by a third party for whom corporate representatives perform services.
¶46 Among the definitions of the word “principal” is “chief” or “most influential.” Webster’s Third New International Dictionary (1966).
¶47 If his tax form asked for the address of his principal place of business, respondent would certainly have given his office address (he did, of course, give that address as his business address on the relevant tax forms). It borders on the absurd to suggest that he should have identified a place over which he has no control or dominion as his place.
¶48 Most, if not all, of the uncertainty in cases debating the relative merits of the “focal point” test and the “facts and circumstances” test, as well as the uncertainty that today’s opinion is sure to generate, would be eliminated by defining the term “place of business” to encompass only property that is owned or leased by the taxpayer or his employer.
