delivered the opinion of the Court.
In 1970 the people of Illinois amended its constitution 1 adding Art. IX-A to become effective January 1, 1971, and reading:
“Notwithstanding any other provision of this Constitution, the taxation of personal property by valuation is prohibited as to individuals.”
There apparently appeared on the ballot when Art. IX-A was approved the following:
“The amendment would abolish the personal property tax by valuation levied against individuals. It would not affect the same tax levied against corporations and other entities not considered in law to be individuals. The amendment would achieve this result by adding a new article to the Constitution of 1870, Article IX-A, thus setting aside existing provisions of Article IX, Section 1, that require the taxation by valuation of all forms of property, real and personal or other, owned by individuals and corporations.”
Respondent Lake Shore Auto Parts Co., a corporation, brought an action against Illinois officials on its behalf *358 and on behalf of all other corporations and “non-individuals” subject to the personal property tax, claiming that the tax violated the Equal Protection Clause of the Fourteenth Amendment since it exempts from personal property taxes all personal property owned by individuals but retains such taxes as to personal property owned by corporations and other “non-individuals.” The Circuit Court held the Revenue Act of Illinois, as amended by Art. IX-A, unconstitutional as respects corporations by reason of the Equal Protection Clause of the Fourteenth Amendment.
Shapiro and other individuals also brought suit alleging they are natural persons who own personal property, one for himself and his family, one as a sole proprietor of a business, and one as a partnership. A different trial judge entered an order in these cases dismissing the complaints except as to Shapiro and members of his class. The trial judge held that all other provisions of Illinois law imposing personal property taxes on property owned by corporations and other “non-individuals” were unaffected by Art. IX-A, in line with the statement on the ballot, quoted above.
All respondents in both cases appealed to the Illinois Supreme Court, which held that Art. IX-A did not affect all forms of real and personal property taxes but only personal property taxes on individuals, which it construed to mean
“ad valorem
taxation of personal property owned by a natural person or by two or more natural persons as joint tenants or tenants in common.”
The Equal Protection Clause does not mean that a State may not draw lines that treat one class of individuals or entities differently from the others. The test is whether the difference in treatment is an invidious discrimination.
Harper
v.
Virginia Board of Elections,
“The States have a very wide discretion in the laying of their taxes. When dealing with their proper domestic concerns, and not trenching upon the prerogatives of the National Government or violating the guaranties of the Federal Constitution, the States have the attribute of sovereign powers in devising their fiscal systems to ensure revenue and foster their local interests. Of course, the States, in the exercise of their taxing power, are subject to the requirements of the Equal Protection Clause of the Fourteenth Amendment. But that clause imposes no iron rule of equality, prohibiting the flexibility and variety that are appropriate to reasonable schemes of state taxation. The State may impose different specific taxes upon different trades and *360 professions and may vary the rate of excise upon various products. It is not required to resort to close distinctions or to maintain a precise, scientific uniformity with reference to composition, use or value.”
In that case we used the phrase “palpably arbitrary” or “invidious” as defining the limits placed by the Equal Protection Clause on state power.
Id,.,
at 530. State taxes which have the collateral effect of restricting or even destroying an occupation or a business have been sustained, so long as the regulatory power asserted is properly within the limits of the federal-state regime created by the Constitution.
Magnano Co.
v.
Hamilton,
“We cannot say that investigation in these fields would not disclose a basis for the legislation which would lead reasonable men to conclude that there is just ground for the difference here made. The existence, unchallenged, of differences between the taxation of incomes of individuals and of corporations in every federal revenue act since the adoption of the Sixteenth Amendment, demonstrates that there may be.” Id., at 283-284.
It is true that in
Quaker City Cab Co.
v.
Pennsylvania,
“If usually there is an important difference of degree between the business done by corporations and that done by individuals, I see no reason why the larger businesses may not be taxed and the small ones disregarded, and I think it would be immaterial if here and there exceptions were found to the general rule. . . . Furthermore if the State desired to discourage this form of activity in corporate form and expressed its desire by a special tax I think that there is nothing in the Fourteenth Amendment to prevent it.” Id., at 403.
Each of these dissenters thought
Flint
v.
Stone Tracy Co.,
“[I]t could not be said, even if the principles of the Fourteenth Amendment were applicable to the present case, that there is no substantial difference be *362 tween the carrying on of business by the corporations taxed, and the same business when conducted by a private firm or individual. The thing taxed is not the mere dealing in merchandise, in which the actual transactions may be the same, whether conducted by individuals or corporations, but the tax is laid upon the privileges which exist in conducting business with the advantages which inhere in the corporate capacity of those taxed, and which are not enjoyed by private firms or individuals. These advantages are obvious, and have led to the formation of such companies in nearly all branches of trade. The continuity of the business, without interruption by death or dissolution, the transfer of property interests by the disposition of shares of stock, the advantages of business controlled and managed by corporate directors, the general absence of individual liability, these and other things inhere in the advantages of business thus conducted, which do not exist when the same business is conducted by private individuals or partnerships. It is this distinctive privilege which is the subject of taxation, not the mere buying or selling or handling of goods which may be the same, whether done by corporations or individuals.” Id., at 161-162.

White River Co.
v.
Arkansas,
*363
In
Rapid Transit Co.
v.
New York,
“Since carriers or other utilities with the right of eminent domain, the use of public property, special franchises or public contracts, have many points of distinction from other businesses, including relative freedom from competition, especially significant with increasing density of population and municipal expansion, these public service organizations have no valid ground by virtue of the equal protection clause to object to separate treatment related to such distinctions.” Id., at 579.
We reached the same result in
Nashville, C. & St. L. R. Co.
v.
Browning,
*364 Approval of the treatment “with that separateness” which distinguishes public service corporations from others, ibid., leads us to conclude in the present cases that making corporations and like entities, but not individuals, liable for ad valorem taxes on personal property does not transcend the requirements of equal protection.
In
Madden
v.
Kentucky,
“A state legislature, in the enactment of laws, has the widest possible latitude within the limits of the Constitution. In the nature of the case it cannot record a complete catalogue of, the considerations which move its members to enact laws. In the absence of such a record courts cannot assume that its action is capricious, or that, with its informed acquaintance with local conditions to which the legis *365 lation is to be applied, it was not aware of facts which afford reasonable basis for its action. Only by faithful adherence to this guiding principle of judicial review of legislation is it possible to preserve to the legislative branch its rightful independence and its ability to function.” Id., at 510.
Illinois tells us that the individual personal property tax was discriminatory, unfair, almost impossible to administer, and economically unsound. Assessment practices varied from district to district. About a third of the individuals paid no personal property taxes at all, while the rest paid on their bank accounts, automobiles, household furniture, and other resources, and in rural areas they paid on their livestock, grain, and farm implements as well. As respects corporations, the State says, the tax is uniformly enforceable. Illinois says, moreover, that Art. IX-A is only the first step in totally eliminating the ad valorem personal property tax by 1979 but for fiscal reasons it was impossible to abolish the tax all at once.
We could strike down this tax as discriminatory only if we substituted our judgment on facts of which we can be only dimly aware for a legislative judgment that reflects a vivid reaction to pressing fiscal problems. Quaker City Cab Co. v. Pennsylvania is only a relic of a bygone era. We cannot follow it and stay within the narrow confines of judicial review, which is an important part of our constitutional tradition.
Reversed.
Notes
In 1969, the Illinois Legislature had provided for the submission of the proposed amendment to a referendum vote.
The result was either to reverse with directions to dismiss the complaints or to affirm the judgment that dismissed the complaints. Those two cases were heard by the Illinois Supreme Court along with *359 a petition to file original suit with that court by one Maynard, who owned nonbusiness personal property, and by three school districts. That petition was dismissed.
Classic examples are the taxes that discriminated against newspapers, struck down under the First Amendment
