I dissent.
Issues
This case presents the following questions: (1) whether the tax enacted by the City of Oakland is an “income tax” or a “license tax”; and, (2) assuming that the subject tax is found to be an “income tax,” whether a chartered city may, in the exercise of powers conferred by the home rule provisions of the California Constitution (art. XI, § 5, subd. (a)), levy such a tax.
The majority holds that the tax in question is “. . . an occupation tax substantially resembling the type of municipal license fee long approved by . ..” this court, and specifically, in the language of the last paragraph of Revenue and Taxation Code section 17041.5, a “license tax upon a business measured by or according to gross receipts.” (Ante, p. 390.) Since finding the tax in issue a license tax was dispositive, the majority concluded that it need not address the constitutional issue.
*411I respectfully conclude that; (1) the tax enacted by the City of Oakland is an “income tax”; and, (2) a chartered city may not, in the exercise of powers conferred by the home rule provisions of the Constitution, levy such a tax.
It has been observed that one’s point of view often depends upon one’s viewpoint. The perspective from which an issue is viewed may affect its understanding. Approaching the questions here presented without an examination of the context in which they arose, is to meet the issues before us with “blinders.” Problems of the law are not always effectively resolved by word labels or dictionary definitions. Therefore, let us first examine the events which preceded the enactment of Ordinance No. 9021, adding section 5-1.65 to chapter 5, article 1, of the Oakland Municipal Code on June 13, 1974.
Background
A. Revenue Crisis
The 1960’s brought a revenue crisis to California cities. Factors contributing to the crisis included expanding population with increased urbanization; demand for expanded municipal services; increased cost of services resulting from inflation; and social and economic patterns of growth extending outside political boundaries. An example of the last problem was the growth of large numbers of nonresident commuters. (Januta, The Municipal Revenue Crisis: California Problems and Possibilities (1968) 56 Cal.L.Rev. 1525, 1526.) By 1965 it was evident that competition for tax dollars had increased inter-city tax conflicts. (Sato, Municipal Occupation Taxes in California: The Authority to Levy Taxes and the Burden on Intrastate Commerce (1965) 53 Cal.L.Rev. 801.)
The largest source of revenue for California cities was the property tax. (Januta, supra, 56 Cal.L.Rev. at p. 1526 & fn. 6.) However, there was great dissatisfaction with the property tax. It was under attack as unfair, disruptive of economic activity, and difficult to administer. It was also thought to be reaching its economic and political limit. (Januta, supra, pp. 1528-1540.)
By 1968, one solution advanced to meet California’s city revenue problem was adoption of a municipal income tax. (Januta, supra, pp. 1540-1558.) Cities in other states had turned to the municipal income tax as one alternative. At that time at least 170 cities outside California *412were employing an income tax. (Legislative Developments, The Limits of Municipal Income Taxation: The Response in Ohio (1970) 7 Harv.J.Legis. 271.) It had proven easy to administer and capable of raising substantial revenues. (Januta, supra, 56 Cal.L.Rev. 1525.)
Why had no California City, prior to 1968, enacted a municipal income tax? The state had expressly prohibited all California cities from levying a local income tax: “Notwithstanding any statute, ordinance, regulation, rule or decision to the contrary, no city, ... whether chartered or not, shall levy or collect or cause to be levied or collected any tax upon the income, or any part thereof, of any person, resident or nonresident.” (Rev. & Tax. Code, § 17041.5.) The effect of this prohibition will be considered more fully in our subsequent discussion. Its existence, however, explains why California cities were deterred from enacting income tax measures prior to 1968. (Januta, supra.)
Was there any exception to this prohibition? The second paragraph of section 17041.5 contained the following provision: “This section shall not be construed so as to prohibit the levy or collection of any otherwise authorized license tax upon a business measured by or according to gross receipts.” (Italics added.)
B. San Francisco Tax
It was out of this milieu that the City and County of San Francisco, on August 19, 1968, enacted ordinance 246-68, the preamble of which provided in part: “An Ordinance Providing For The Imposition Of License Fees For The Privilege Of Engaging In Occupations, Trades And Professions In ... San Francisco By All Non-Resident Persons Employed By Others . ...” (Comment, The Validity of San Francisco’s Commuter Tax (1969) 20 Hastings L.J. 813, fn. 1.) The ordinance imposed a tax of 1 percent upon the gross income earned by nonresidents in San Francisco. Note the language: “license fees shall be measured by one percent (.01) of the gross receipts of each such person . ...” (Id., at fn. 2.) The measure of the tax was wages and salaries which would normally be termed “gross income.” The implementing provisions included apportionment and employer withholding. (Id., at fn. 3.) This tax was popularly referred to as the “commuter tax.” (Id.) San Francisco authorities argued commuters exploited city residents. However, a contrary argument may be made. (Sato, “Municipal Affairs” in California (1972) 60 Cal.L.Rev. pp. 1105, 1106, fns. 193, 199.)
*413The reaction of surrounding bay area counties was strong and swift. On September 13, 1968, the counties of Alameda, Contra Costa, Marin, San Mateo, and Santa Clara filed an action in the County of Sonoma seeking to enjoin the San Francisco ordinance and for declaratory relief. One of the arguments advanced in the trial court was that the San Francisco tax was an “income tax” imposed under the guise of a “license tax,” and hence invalid. (20 Hastings L.J. 813, supra, at p. 819, fn. 49.)
At the very time the San Francisco ordinance was under consideration, the Legislature, at the behest of legislators from surrounding cities (Januta, supra, 56 Cal.L.Rev. at p. 1550), was acting forcefully and quickly to outlaw such taxes by adopting Government Code section 50026, which provides as follows: “The legislative body of any local agency, chartered or general law, which is otherwise authorized by law or charter to impose any tax on the privilege of earning a livelihood by an employee or any other tax, fee or charge on or measured by the earnings, or any part thereof, of any employee, shall not impose any such tax, fee or charge on the earnings of any employee, when such employee is not a resident of the taxing jurisdiction, unless exactly the same tax, fee or charge at the same rate, with the same credits and deductions, is imposed on the earnings of all residents of the taxing jurisdiction who are employed therein.” (Added by Stats. 1968, ch. 559, § 1, p. 1225.)
Thus, the Legislature, faced with the San Francisco tax proposal, prohibited enactment of “commuter tax” measures, such as that adopted by San Francisco. Was the Legislature, by the language employed, inferring that it approved a “.. . tax, fee or charge on or measured by the earnings, or any part thereof, of any employee .. .” contrary to the prohibition of Revenue and Taxation Code section 17041.5? This question is more fully answered in our subsequent discussion. Suffice it at this point to say that such does not seem to be the case, for the Legislature, out of what appears as greater caution, and perhaps being fearful of just such an interpretation, added a second paragraph to section 50026, providing: “This section shall not be construed as authorizing any tax prohibited by section 17041.5 of the Revenue and Taxation Code or any other provision of law . ..” (italics added).
There was, however, as previously observed, an exception in section 17041.5 regarding license taxes on businesses measured by gross receipts. The Legislature, in an apparent effort to also preserve that exception, added the following final clause to section 50026: “.. . nor shall it be construed so as to prohibit the levy or collection of any otherwise *414authorized tax upon a business measured by or according to gross receipts.” The words “. .. tax upon a business measured by or according to gross receipts” were identical to the words employed in section 17041.5.
Returning to the action filed by Alameda and other counties, the trial court held the San Francisco ordinance invalid. The Court of Appeal affirmed, but a petition for hearing was not lodged with this court. (County of Alameda v. City and County of San Francisco (1971) 19 Cal.App.3d 750 [97 Cal.Rptr. 175, 48 A.L.R.3d 332].) The appellate court, found the tax arbitrary, unreasonable, and discriminatory—denying “... to nonresidents the equal protection of the laws.” (Id., at pp. 756-757.) The appellate court neither addressed nor decided the two issues presented in the case at bar. Therefore, the effect of the holding was to leave open these issues. The form of the San Francisco tax suggested a way to avoid the “income tax” prohibition of section 17041.5. In fact, in a footnote the appellate court encouraged cities intent upon such taxation by observing: “Although Government Code, section 50026, is obviously intended to prohibit the precise type of ordinance enacted by San Francisco, it is at least questionable that the Legislature possesses the power to prohibit a city from exercising its inherent power of municipal taxation. [Citation omitted.] We cite the section solely as an indication of legislative intent.” (Id., p. 757, fn. 3.)
Encouragement to follow the San Francisco lead came from other sources. The decision in the Alameda case was rendered on August 30, 1971. Also in 1971, while that case was pending, a Comment in 11 Santa Clara Law. at page 343, was published, concluding that a municipal income tax was valid. Subsequently, in June 1972, another commentator came to the same conclusion. (Sato, “Municipal Affairs” in California, supra, 60 Cal.L.Rev. at p. 1099, fn. 177.)
C. Taxing Commuters
Various assertions were made in connection with the San Francisco tax as to the number of commuters affected by the tax. (Alameda case, supra, 19 Cal.App.3d at p. 752; Comment, supra, 20 Hastings L.J. at p. 824, fn. 82.) Actual figures covering cities in California were released by the Census Bureau in June of 1973. (U. S. Bureau of the Census, Census of Population: 1970, Subject Reports: Journey to Work. (Issued June 1973.)) The figures disclosed were dramatic illustration of the treinendous movement of workers in and out of central cities.
*415Although the study indicated that many residents did not disclose their place of employment, among those who did disclose it was revealed that there were more nonresident commuters working in the City of Oakland in 1970 than residents there employed. The figures were 81,000 nonresident workers as compared with only 70,931 resident workers. (Id., p. 198.) It appeared that a tax levied on gross income of all residents and nonresidents employed in Oakland in 1970 would have resulted in 151,931 taxpayers; a tax on all residents employed in Oakland would have resulted in 70,931 taxpayers.
The situation in Oakland was reflected in other cities as well. For San Francisco, it was 419,831 resident and nonresident workers compared with 252,658 resident workers (Id., p. 200); for Sacramento, 153,792 resident and nonresident workers compared with 68,099 resident workers (Id., p. 186, again, more nonresident than resident workers); for Palo Alto, 50,282 resident and nonresident workers compared with only 10,325 resident workers. (Id., p. 203, substantially more nonresident than resident workers.)
The Oakland tax was, it would appear, in a real sense, a “commuter tax,” even though levied on both residents and nonresidents. The release of this data in 1973 brings us full circle to the adoption of the subject tax in June of 1974. Let us now turn to the first question posed.
Income Or License Tax
A. Overview
Like the San Francisco “commuter tax,” the Oakland tax is labeled a “license fee” for the privilege of engaging in or following any business, trade, occupation or profession as an employee. The fee is measured by 1 percent of gross receipts in excess of a base figure. (§ 5-1.65.) Gross receipts are defined to include “... all salaries, wages, commissions, bonuses, or other money payments of any kind ....” (§ 5-1.65(g).) Employers are required to withhold the tax. (§ 5-1.65(i).) The only distinct difference from the San Francisco tax is that the Oakland tax is on both residents and nonresidents who work in Oakland. (§ 5-1.65.)
Although the instant tax is designated a “license fee,” such declaration is not determinative. This court must look to substance and not mere form. (Ingels v. Riley (1936) 5 Cal.2d 154, 159 [53 P.2d 939, 103 A.L.R. 1]; San Francisco v. Boss (1948) 83 Cal.App.2d 445, 450 [189 P.2d 32].) *416Classification of a taxing measure is based upon its incidents and the natural and legal effect of the language used. (Dawson v. Kentucky Distilleries & Warehouse Co. (1921) 255 U.S. 288, 292 [65 L.Ed. 638, 645, 41 S.Ct. 272]; Douglas Aircraft Co., Inc. v. Johnson (1939) 13 Cal.2d 545, 550 [90 P.2d 572]; Ingels v. Riley, supra, 5 Cal.2d 154.) Let us examine the tax to determine its true nature.
B. Identifying Characteristics
Perhaps the most striking feature of the tax is its application to all employees in all occupations, trades, and professions. In this regard, the tax is unlike the usual license tax on a specific or several specific occupational or business groups. In this way the tax is like an income tax, since such taxes are normally levied upon all income, no matter what the business or occupational source.
The tax is upon the individual employee (“. .. upon persons who .. .”) rather than upon the employment (i.e., lawyers, dry cleaning establishments, retail sales). Income taxes are also levied against persons rather than occupations, trades, or businesses, as is the case with license taxes. Thus, income taxes are directed against the fact of income, whereas license taxes are directed against the fact of employment. By these standards the tax is clearly an income tax.
Historically, and even by definition, license taxes involve the issuance of a “license” to the activity granted the privilege of doing business. Licenses take various forms, but often look like a certificate. Some are prominently displayed in the business establishment. Such licenses are usually granted to dispose of property, pursue a business, occupation or calling, or to exercise a privilege. (Ingels v. Riley, supra, 5 Cal.2d at p. 157). The Oakland tax makes no provision for the issuance of licenses, nor did the San Francisco commuter tax.
One strongly identifying mechanism of the modem income tax is its withholding provision, a feature characteristic of state and federal income taxes. Municipal income taxes, as employed in other states, usually contain this provision. (Legislative Developments, supra, 7 Harv.J.Legis. at p. 273.) On the other hand, license taxes are not usually collected in this manner.
The “gross receipts” occupation tax does have a venerable history in California. (Ante, p. 394, and cases cited.) However, examination reveals *417that such taxes have been upon the privilege of engaging in a specific area of activity. Such is not true of the income tax, nor of the Oakland tax.
The subject tax is a percentage of the monetary proceeds of labor— characteristic of the income tax. Furthermore, the tax here employed is upon the same source which the State of California includes in its definition of “gross income.” (Rev. & Tax. Code, § 17071, subd. (a) (1).)
The tax under consideration is upon all employees. The city contends that employee services are like any other trade or profession, in a generic sense, and hence are as subject to “license tax” as any trade or profession. They are not so treated in other taxing areas. For example, “employee services” are not a “trade or profession” for federal self employment tax purposes. (26 U.S.C. § 1402(c)(2) and (3))
C. Municipal Income Taxes
The city alludes to the fact that “gross income” under state law (Rev. & Tax. Code, § 17071) and the federal income tax statute, (Int. Rev. Code, §61) includes “interest,” “rents,” “royalties,” and other sources which the Oakland tax does not reach. Further, the city asserts that the normal income tax is based on net income after deduction of business expenses and costs of production of income, whereas the Oakland tax is a gross levy. Thus, it argues, the gross receipts feature of Oakland’s levy, like some license taxes, together with credit for duplicative license fees, evidences a coordinated business tax system. Let us examine these assertions.
First, section 17041.5 prohibits cities from imposing a tax not only upon “income” per se, but upon “any part thereof’; thus, the fact that Oakland seeks to tax only compensation for services, and not other sources, does not mean that the Oakland tax is any less a prohibited tax. Second, Revenue and Taxation Code, section 17071 lists “compensation for services” as one category of income, and “gross income derived from business” as another, illustrating that under California tax statutes, for tax purposes, there is a distinction between business receipts and employee compensation. The city would blur and thus obliterate this distinction. Third, while the subject tax is distinct in structure and operation from complex state and federal income tax measures, it is very like the typical municipal income tax.
*418City income taxes, as they exist in jurisdictions which permit them, tend to be: (1) flat-rate (i.e., not graduated); (2) levied upon earned income; (3) without deductions, other than perhaps an initial exclusion of a designated amount; (4) collected by employer withholding; and (5) at the rate of either Vi or 1 percent. Oakland’s tax has the exact profile of a typical municipal income tax. {Legislative Developments, supra, 7 Harv.J.Legis. at p. 273; Januta, supra, 56 Cal.L.Rev. at p. 1555 & fn. 151.)
Finally, the giving of a credit for duplicative license fees, rather than evidencing a coordinated business tax system, became a necessary credit when the city sought collection twice from the same source.
The majority, while concurring that city income taxes generally resemble the Oakland tax, points to the typical municipal income tax as being one imposed upon “... all earned income of city residents, whether for services rendered inside or outside the taxing jurisdiction” as demonstrating that the Oakland tax is significantly different from the conventional municipal income tax. (Ante, p. 393.)
However, one reason the typical ordinance is so structured is that in “... most ordinances a credit is allowed to a resident whose income is being taxed by another municipality up to the amount of the local tax . .. .” (Legislative Developments, supra, 7 Harv.J.Legis., at p. 273.) Furthermore, census figures indicate that, at least as of 1970, the Oakland tax was structured to reach 13,263 more taxpayers by taxing nonresidents and residents who work in Oakland than by taxing Oakland residents who worked in and out of Oakland. (U. S. Census, supra, p. 198.) The deviation in form appears to have rendered Oakland a substantial financial benefit. Finally, since Oakland labeled its tax a “license tax” and attempts to exempt it from the first paragraph of section 17041.5, as a “license tax upon a business measured by or according to gross receipts,” Oakland was faced with the California “license tax” cases holding that such “license tax” could not be based on income derived outside the taxing jurisdiction. (City of Los Angeles v. Belridge Oil Co. (1954) 42 Cal.2d 823, 831-833 [271 P.2d 5], app. dism. 348 U.S. 907 [99 L.Ed. 711, 75 S.Ct. 292]; Ferran v. City of Palo Alto (1942) 50 Cal.App.2d 374 [122 P.2d 965].) By taxing only residents who work in Oakland, and commuters, Oakland gained more taxpayers and at the same time avoided the extraterritorial problem to which the label adopted subjected the tax.
*419The majority examined business or occupation tax cases and gross receipts occupation tax cases at length (ante, p. 394); concluding that the Oakland tax differs materially from other license taxes in that: (1) it covers all trades, and professions; and (2) it reaches the individual employee; both characteristics of an income tax and reviewed earlier in this dissent. However, the majority uses this observation as a springboard to conclude that the city not only has the power to tax a part, but also has the power to tax the whole. In other words, the majority asserts that there is no serious question but what a municipality may tax every single occupation (i.e., each worker’s job) within the city. (Ante, p. 395.) Thus concluding, the majority then asserts that such tax is not converted to an income tax simply because measured by employee compensation. That is, the measure or mode of ascertaining a tax is not conclusive as to its nature. (Ante, pp. 396-397.) The majority next observes that Oakland’s tax is exacted only from persons exercising the privilege of selling services in the city and only to the extent they do so. (Ante, pp. 396-397.) Finally, the majority gives deference to its label, and finds it is the privilege and not the income generated which is taxed, citing City of Louisville v. Sebree (1948) 308 Ky. 420 [214 S.W.2d 248, 253-254], (Ante, p. 397.)
In summary, in order to avoid conflict with section 17041.5, the majority reasons: (1) a city may tax every job in the city; (2) though the tax be measured by compensation, that is not conclusive as to its nature; (3) just those exercising the privilege of selling services are taxed, and to the extent services are sold; (4) the label is entitled to deference; (5) it is the privilege and not the income generated by its exercise which is taxed; and (6) hence the Oakland tax is an excise or license tax. Let us review this reasoning.
Section 17041.5 is in two parts. The first part states what the city may not do. It may not levy any tax upon the income, or any part thereof, of any person, resident or nonresident. The second part states what the city may do. It may levy a license tax upon a business measured by gross receipts.
The majority reasons that the city may levy a license tax upon every job in the city. This may be true; however, the city has measured that tax by the gross income of each employee. In its next step in reasoning the majority asserts that the measure (here admittedly employee compensation) is not conclusive as to its nature. That is a correct statement, as far as it goes; but it does not answer the challenge of the first part of section 17041.5. The Oakland tax is on income, or a part thereof. In order to *420avoid the proscription of section 17041.5, the tax must be brought under the second paragraph of that section. This the majority seeks to do by its last three steps in reasoning: (3) just those exercising the privilege of selling services are taxed; (4) the label is entitled to deference; and (5) it is the privilege and not the income taxed. Further confirmation that this is what the majority is asserting is found in its statement that Oakland’s license fee is “... expressly authorized by the final paragraph of section 17041.5. ” (Ante, p. 391.)
How has the majority reached the conclusion that the tax is authorized by the last paragraph of section 17041.5? There is nothing in steps (3), (4) and (5) above which leads to that conclusion, except perhaps deference to label. In fact, the last paragraph of section 17041.5 is not discussed by the majority at any point in the reasoning cited. (Ante, pp. 395-397.) Yet, this is the heart of the issue posed. Is the Oakland tax a “.. . license tax upon a business measured by or according to gross receipts?” Let us address that question.
Whether the Oakland tax is a license tax or an income tax has been treated at length above. That discussion applies to the use of the term “license tax” in section 17041.5. Next, section 17041.5 says “upon a business.” Here lies a second stumbling block. The Oakland tax is not “upon a business.” It is upon “persons” holding jobs in Oakland measured by their gross compensation. Why did the Legislature use the words “business measured by or according to gross receipts” in section 17041.5? The most logical explanation is that the Legislature used that language to exempt the traditional municipal business license taxes measured by gross receipts. These were familiar to legislators at the time of the enactment. Such taxes represent excise taxing practice employed by cities over many years. To sustain the majority conclusion, the Legislature would have had to intend, by the last paragraph of section 17041.5, that a “license tax upon a business measured by or according to gross receipts” meant a percentage levy on the gross income of every employee. Yet, that is the very tax prohibited in the first paragraph of section 17041.5. It would seem clear that the Legislature had no such intention.
Employee compensation (i.e., gross income) may not be taxed under the first paragraph of section 17041.5. To avoid this prohibition the city has labeled its tax on gross income one on “gross receipts.” This is done to qualify employee compensation for the exception of the second paragraph of section 17041.5. When it comes to fitting a tax on gross *421income of employees into the term “gross receipts” in the second paragraph of section 17041.5, the city is faced with the qualifying language “tax upon a business measured by or upon gross receipts.” A tax on employee compensation could be upon a “business” or it could not, depending on who is taxed and for what.
Lastly, the majority concluded this portion of its discussion with a citation to the Sebree case. (Ante, p. 397.) The Sebree case involved interpretation of a Louisville, Kentucky, occupation tax measured by earnings or profits. The court held that such tax was not an “income tax” within the meaning of the Kentucky Constitution. Actually, the United States Supreme Court, interpreting the very same Louisville occupation tax held that it was an “income tax” for purposes of the Buck Act. (Howard v. Commissioners of Louisville (1953) 344 U.S. 624, 629 [97 L.Ed. 617, 622, 73 S.Ct. 465]); see also, Dole v. City of Philadelphia (1940) 337 Pa. 375 [11 A.2d 163], similar measure held to be an “income tax.”) Also, the opinion in Sebree acknowledged that a similar tax in Missouri had been found to be an income tax. (Carter Carburetor Corp. v. St. Louis (1947) 356 Mo. 646, 653 [203 S.W.2d 438, 440].) The Carter tax was labeled an “earning tax” and was imposed on residents and nonresidents earning income in St. Louis.
D. Government Code Section 50026
This brings us to the majority discussion of Government Code, section 50026. (Ante, pp. 397-398, 412-413, quoting the text of § 50026 in full.) As observed above, when San Francisco was about to adopt its “commuter tax” on gross income (the sister tax to the Oakland tax), the Legislature reacted by quickly enacting section 50026 invalidating that kind of levy. The majority asserts that section 50026 is “pointless and redundant if section 17041.5 is construed as enjoining all municipal occupation taxes measured by employee compensation . . . .” (Ante, p. 397.)
It is neither “pointless nor redundant” when viewed in the context of events as they were transpiring in 1968. San Francisco was about to enact a tax on commuters measured by gross income; a tax which was worded like a license tax. The Legislature desired to invalidate such tax. Therefore, the Legislature in section 50026 referred to any chartered city authorized to impose “. .. any tax on the privilege of earning a livelihood by an employee . . .” (the typical occupational license tax language that the San Francisco tax was written to resemble); then, went on to provide “... or any other tax, fee, or charge on or measured by the earnings, or *422any part thereof, of any employee ..(the actual tax measure adopted in the San Francisco tax). Having identified the kind of tax prohibited, section 50026 then went on to outlaw the levying of such a tax upon commuters unless the same tax were levied on residents.
Realizing that by specifically invalidating the discriminatory feature of the San Francisco tax, section 50026 could be interpreted to imply that nondiscriminatory employee taxes measured by gross income were valid, the Legislature added a second paragraph directing that section 50026 “. .. shall not be construed’ as authorizing any tax prohibited by section 17041.5. (Italics added.) Now the majority is doing exactly what the Legislature stated that it should not do. It is construing section 50026 so as to authorize a tax prohibited by section 17041.5. (Ante, pp. 397-398.)
For all of these reasons it is respectfully concluded that the Oakland tax, having the incidence and natural and legal effect of an income tax, is actually an income tax labeled and drafted to appear as a license tax. Having so concluded, it now becomes necessary to determine whether a chartered city may, in the exercise of powers conferred by the home rule provisions of the Constitution, levy such a tax.
Constitutional Issue
A. Home Rule Provision
In California a chartered city derives its power to legislate from a direct constitutional grant. Within the framework of the power granted, a chartered city is an autonomous political entity. (Sato, “Municipal Affairs” in California, supra, at pages 1055-10751; but see Strumsky And The Source Of California Chartered City Powers (1975) 6 Pacific L.J. 85, arguing that Strumsky v. San Diego County Employees Retirement Assn. (1974) 11 Cal.3d 28 [112 Cal.Rptr. 805, 520 P.2d 29], identifies the Legislature as the sole source of a charter city’s powers.)
Pursuant to article XI, section 5, subdivision (a) of the California Constitution charter cities are given the power to “.. . make and enforce *423all ordinances and regulations in respect to municipal affairs, subject only to restrictions and limitations provided in their several charters....” Thus, the power granted is to make laws pertaining to “municipal affairs.” Limitation of the power granted (i.e., to “municipal affairs”) is emphasized by the further qualification that “. .. in respect to other matters . .. (charter cities) shall be subject to general laws.”
Assuming the Oakland tax is an income tax, the second issue is whether Oakland may, in the exercise of its power to legislate respecting municipal affairs, levy such a tax.
B. Municipal Affairs
To the courts has fallen the task of determining the form and content of the general phrase “municipal affairs.” Such determination is based upon the facts and circumstances surrounding each case. (Bishop v. City of San Jose (1969) 1 Cal.3d 56, 62 [81 Cal.Rptr. 465, 460 P.2d 137]; In re Hubbard (1964) 62 Cal.2d 119, 128 [41 Cal.Rptr. 393, 396 P.2d 809]; Professional Fire Fighters, Inc. v. City of Los Angeles (1963) 60 Cal.2d 276, 294 [32 Cal.Rptr. 830, 384 P.2d 158]; In re Braun (1903) 141 Cal. 204, 214 [74 P. 780], conc. opn. by McFarland, referring to them as “loose, indefinable, wild words.”)
Local legislation of a charter city prevails over general law only when the subject matter is “exclusively,” “solely,” or “strictly” a municipal affair. (Professional Fire Fighters v. City of Los Angeles, supra, 60 Cal.2d at p. 291; Ex Parte Nowak (1921) 184 Cal. 701, 704 [195 P. 402, 403].) Conversely, where the subject matter is one of general or statewide concern, general law prevails and the charter city is subject to and controlled by the state legislation. (Bishop v. City of San Jose, supra, 1 Cal.3d at pp. 61-62; Professional Fire Fighters v. City of Los Angeles, supra, 60 Cal.2d at pp. 292-293; Pacific Tel. & Tel. Co. v. City and County of San Francisco (1959) 51 Cal.2d 766, 768-769 [336 P.2d 514]; Pipoly v. Benson (1942) 20 Cal.2d 366, 369-370 [125 P.2d 482, 147 A.L.R. 515].)
As conditions in the state change, what was once a matter of local concern may later become a matter of general or statewide concern controlled by general law. (Pacific Tel. & Tel. Co. v. City and County of San Francisco, supra, 51 Cal.2d at p. 771.) The categories of “municipal affairs” and “of general or statewide concern” are not mutually exclusive. Some portions of a local matter may ultimately become of general state interest. (In re Hubbard, supra, 62 Cal.2d at p. 127.)
*424The opinion in the Professional Fire Fighters case, supra, 60 Cal.2d at pages 293-294, assembled some 23 cases, “all dealing with various phases of municipal affairs held to be subject to general laws on the basis of statewide concern.” A further discussion of matters of general or statewide concern is set forth in 5 Witkin, Summary of California Law (8th ed.) Constitutional Law, section 452.
Have additional rules or guidelines been developed? In the Professional Fire Fighters case, supra, at page 292, Justice Peters, writing for a unanimous court, concluded from review of the case authorities, that “.. . general law prevails over local enactments of a chartered city, even in regard to matters which would otherwise be deemed to be strictly municipal affairs, where the subject matter of the general law is of statewide concern.” Note that this statement does not suggest a “balancing test” between state and local interests. To the contrary, the inquiry is directed to determination of the presence of a statewide concern, and if the matter is of statewide concern, that determines the issue. On the question of what is of local or statewide concern the opinion states: “This question must be determined from the legislative purpose in each individual instance. In the instant case it would appear that the Legislature was attempting to deal with labor relations on a statewide basis.” (Id., p. 294.) The court found “labor relations” a statewide concern. (Id., p. 295.)
How do the doctrines of conflict and preemption affect the inquiry? Unfortunately, these issues have at times injected confusion into the municipal affairs question. Whereas charter cities derive their “home rule” authority from section 5 of article XI, every city (charter and general law) is granted so-called police powers under section 7 of article XI to “... make and enforce within its limits all local, police, sanitary and other ordinances and regulations not in conflict with general laws.” (Italics added.) It is from this general grant and the “not in conflict” limitation that the issues of conflict, preemption, and occupation of the field are derived. In the case before us, Oakland is not claiming authority to tax under its police powers, because of the preemption statute. (Rev. & Tax. Code, § 17041.5.) Instead, Oakland shifts the battleground to its home rule authority, seeking to avoid the strictures of conflict and preemption.
In the case before us, the issue is statewide concern versus municipal affairs. However, the preemption statute is one important factor evidencing a general statewide concern. Justice Peters explained the interrelationship of preemption and municipal affairs thus: “Although the parties *425argue this issue as one of state preemption, it is not, strictly speaking, predicated on full occupation of the field. The exclusive right of a chartered city ... to regulate turns on whether or not the subject matter is a municipal affair. In other words, if it is exclusively a matter of state concern, chartered cities have no authority to act at all. [Citation omittted.] Of course, a particular subject may be both a municipal affair and of statewide concern. Since the question whether the subject is of state concern is often determined by whether or not the state has enacted legislation, preemption or full occupation of the field may become one, but only one, test of whether the given subject is a municipal affair.” {In re Hubbard, supra, at p. 127; italics added.)
Justice Peters further elaborated upon the rule in his dissent in the Bishop case, supra, 1 Cal.3d at page 66: “In other words, in cases of conflict and preemption, the inquiry ends once a statewide concern is found, and there is no need to weigh the state and municipal concerns or to determine which should predominate.” In other words, no need to weigh such concerns because the problem was not a conflict or preemption problem but a problem of statewide concern under the municipal affairs section. Note again the specific disclaimer of a “balancing test.”
Justice Peters, citing cases to illustrate, suggests that decisions fall into one of four categories (Id., p. 67): (1) solely state concerns, and the subject matters of municipal regulation and the state statute do not affect municipal affairs (Wilson v. Beville (1957) 47 Cal.2d 852, 856-857 [306 P.2d 789]); (2) the subject matter of the municipal regulation and the state statute involves both municipal and statewide concerns (In re Hubbard, supra, 62 Cal.2d 119); (3) the subject matter is one ordinarily subject to municipal regulation, but parts of the subject may also involve statewide concern (Professional Fire Fighters, supra, 60 Cal.2d 276); and (4) the subject matter solely involves municipal affairs and no matters of statewide concern are involved (City of Pasadena v. Charleville (1932) 215 Cal. 384 [10 P.2d 745], a decision the dissent in Bishop would disapprove).
Is there any conflict between the rules and guidelines above stated and the decision of the majority in the Bishop case? It does not appear that there is. First, it should be noted that the views expressed by the majority in the Bishop case on the municipal affairs issue were not necessary to the decision. The majority held that the Legislature did not intend that the state law apply to the setting of salaries of city employees, whether chartered or not. (Bishop v. City of San Jose, supra, 1 Cal.3d at p. 63.) *426Thus, a resolution of the municipal affairs question was not required. Second, the Bishop majority opinion does not disapprove or overrule the Professional Fire Fighters case. The majority opinion in Bishop left those rules intact. Third, and finally, there is nothing in the Bishop majority opinion contrary to the rules hereinabove outlined.
The majority in Bishop stated (supra, 1 Cal.3d at pp. 61-62): “As to . matters which are of statewide concern, however, home rule charter cities remain subject to and controlled by applicable general state laws regardless of the provisions of their charters, if it is the intent and purpose of such general laws to occupy the field to the exclusion of municipal regulation (the preemption doctrine).” At first blush, this statement of the rule seems inconsistent with the language which follows. However, when read with the subsequent statement (supra, p. 63): “... the Legislature is empowered neither to determine what constitutes a municipal affair nor to change such an affair into a matter of statewide concern,” it appears that the majority was merely restating the rule of the Professional Fire Fighters case. The majority in Bishop was not saying that the Legislature literally has no effect on the determination of what matters are of statewide concern by the legislation it enacts. The Bishop majority was saying, in effect: “Since the question whether the subject is of state concern is often determined by whether or not the state has enacted legislation, preemption or full occupation of the field may become one, but only one, test of whether the given subject is a municipal affair.” (In re Hubbard, supra, 62 Cal.2d at p. 127.)
C. Regulation and Revenue
It has been asserted that numerous subjects found to be of statewide concern over the past 80 years all involved activities essentially regulatory in nature.2 In contrast, on the specific issue of taxation for revenue only, numerous cases declare without equivocation or qualification that impos*427ing taxes for revenue purposes is a municipal affair.3 The distinction drawn between regulatory state legislation (of statewide concern) and local taxation for revenue only (a municipal affair) may have historical support; however, there is no reason to conclude that such distinction must be drawn in the instant case. To the contrary, it seems just as evident that the Legislature intended to prohibit local taxation for revenue in order to control the entire field for both regulatory and revenue purposes.
Furthermore, there is no longer any reason to conclude that local tax ordinances are, by their nature, municipal affairs. Local revenue raising has, in many instances, become of compelling statewide concern. One need only view the legislative turmoil over local property tax relief and equalization of school revenues to recognize what an overriding state interest may be involved in local taxation.
Of the cases cited as declaring local taxation for revenue only a municipal affair, all but two did not involve a direct conflict with state law. In most the issue was whether the city was empowered to act at all, even without prohibition by general law. Of the cases cited, only two actually held local ordinances superior to the conflicting state enactment, and both of those arose near the turn of the century and involved the same state statute. (Ex Parte Braun, supra, and Ex Parte Helm (1904) 143 Cal. 553 [77 P. 453].)
Each case cited involved an excise tax. Therefore, with respect to a tax other than an excise tax, the statement that a revenue tax is a municipal affair is dicta. Finally, the tax cases cited involved excise taxes with no extraterritorial effect. In contrast, the tax before us: (1) involves direct conflict with state law; (2) is an income not an excise tax; and (3) has an extraterritorial effect.
The guidelines enunciated in this dissent were applied in Century Plaza Hotel Co. v. City of Los Angeles (1970) 7 Cal.App.3d 616 [87 Cal.Rptr. 166]. There Los Angeles imposed an excise tax of 5 percent upon the purchase of alcoholic beverages sold by a retailer for consumption on the premises. The tax was a local tax for revenue only. The appellate court *428framed the issue as: “Does the Ordinance Represent a Valid Exercise of the Powers of a Charter City Over Its Municipal Affairs?” Finding the matter of statewide concern, the appellate court held the ordinance invalid. Petition for hearing by this court was denied. (Id., at p. 626.)
In thus holding, the appellate court: (1) framed the issue as involving the “home rule” provisions of section 5, subdivision (a), and not the “in conflict with” provisions of section 7 of article XI (id., at p. 620 and fn. 3); (2) found both conflict and preemption (id., at p. 624); (3) noted that under Bishop the legislative intent is not conclusive (id., at p. 625); (4) examined the reasons for preemption expressed by the Legislature (id.); (5) examined matters of statewide concern (id., at p. 626); and (6) found “no purely municipal affair ... but a matter of statewide significance.” In short, the court of appeal applied the analysis of the Professional Fire Fighters and Bishop cases, as set forth above.
Applying these rules and guidelines, the first question presented is whether there is conflict or preemption in the case before us.
D. Preemption
The Legislature, pursuant to the authority granted under article XIII, section 26, subdivision (a), adopted a comprehensive state income tax system in 1935. (Stats. 1935, ch. 329, p. 1090 et seq.) Section 17041.5, a part of the state income tax regulatory and revenue raising system, prohibits charter cities from levying a tax upon the income, or any part thereof, of any person, resident or nonresident. (See Rev. & Tax. Code, §§ 17001 to 19500 for state income tax provisions.) There could be no more definite case of preemption than that seen here.
The preemption section enacted in 1963 was initially effective for two years. However, in 1965, the section became permanent by reason of the repeal of the automatic repealer clause. The intent to preempt was reaffirmed by the Legislature in 1968. Acting to outlaw the San Francisco commuter tax on income, the Legislature specifically stated: “This section shall not be construed as authorizing any tax prohibited by section 17041.5 of the Revenue and Taxation Code or any other provision of law . ...” (Gov. Code, § 50026.)
E. Statewide Concern
Finding preemption evidences a strong indication that the subject matter is of statewide concern. Here the field has been occupied by a *429comprehensive statute, and local legislation has been specifically prohibited. The importance of preemption as one factor showing statewide concern is illustrated by the statement of Justice Peters in the Bishop case: “If it be assumed that there are some matters so local in nature that the Legislature’s power to regulate will be limited to nonchartered cities ... it is apparent that such matters must be veiy rare.” (Bishop case, supra, 1 Cal.3d at pp. 68-69.)
The extraterritorial effect of the Oakland tax is obvious. This court has taken judicial notice of the rapid growth of suburban areas in California and the high rate of mobility of the citizens of the state. (In re Lane (1962) 58 Cal.2d 99, 111 [22 Cal.Rptr. 857, 372 P.2d 897] (conc. opn.).)
In the 1968 reaffirmance of the intent to preempt set forth in Government Code, section 50026, the Legislature declared: “The Legislature finds and declares that the right of citizens of California to move freely about the state in search of employment is a matter of statewide interest and concern. Any unnecessary barriers which impede the mobility of citizens of this state or limit their choice of employment are contrary to state policy.” (Stats. 1968, ch. 559, § 3.)
Other factors evidencing statewide concern include: (1) the effect of the tax on out-of-county workers regarding free inter-city travel; (2) the effect on nonresident work decisions; (3) the redirection of business market forces; and (4) the effect on nonresident residential decisions. All these factors demonstrate extraterritorial impact.
It appears that large numbers of commuters are subject to the Oakland tax. These persons have no voice in the adoption of such tax, the level of tax imposed, the duration of the levy, or even the expenditure of the tax proceeds thus extracted. It is taxation without representation, a matter of evident statewide concern.
If the subject tax were held to be a municipal affair, the entire municipal field would be opened to creation of a crazy quilt of overlapping taxing jurisdictions. Drawing from the federal-state parallel: “If fifty independent economic units within the United States are undesirable, 387 economic enclaves within California would be intolerable.” (Sato, supra, 53 Cal.L.Rev. 801, 818 (1965); see also, City of Los Angeles v. Shell Oil Co. (1971) 4 Cal.3d 108, 119 [93 Cal.Rptr. 1, 480 P.2d 953].) Such taxation problems are indeed matters of grave statewide concern.
*430The issue before us should not be encapsulated. Viewed from outside its geographic boundaries, it is apparent Oakland is not a law unto itself. Other communities will be affected by and react to the Oakland tax—in some the tax may well spark retaliation. These too are matters of statewide concern.
Neither the economic wisdom nor the social propriety of a municipal income tax is within our purview. These are, however, matters of concern to the Legislature; and to the degree such taxing decisions affect nonresident citizens and other taxing structures, such matters are of statewide concern.
Local income taxes, such as at issue here, have been criticized as regressive, imposing the greatest proportionate burden on those whose income is lowest. Excluding interest, dividends, and capital gains also favors the rich. The tax fails to recognize that gross income is not always an accurate measure of taxpaying abilities. (Legislative Developments, supra, 7 Harv.J.Legis., at pp. 274-281.) Proponents argue that the low rate reduces the inequities. There is no guarantee such rates will remain low, especially in view of rising costs and increased reluctance to raise property taxes.
The license tax form creates arbitrary results. Neighbors, one working within the city and one without, are taxed at different levels—yet receive identical services. Nonresidents do not receive the same benefits as residents, yet both are taxed at the same rate. The tax is also thought unfair to those commuters who may live in a community without income taxes but with resultingly high property taxes. Such commuters could be required to pay both taxes. All of these alleged inequities are not for us to evaluate, but they are matters of statewide concern, once one’s perspective exceeds the geographic boundaries of Oakland.
For all of these reasons, I respectfully conclude that the subject matter is of general or statewide concern and the instant tax is invalid. The judgment of the trial court should be affirmed. .
