Among the oldest principles of constitutional law is that a state may not tax the United States. That issue has been settled since 1819, when the Supreme Court held in
McCulloch v. Maryland,
One issue courts have had to decide is whether the assessment in question should be characterized as a tax, and thus impermissible when imposed on a federal entity, or whether the assessment should be considered a fee for services provided to the federal entity, and therefore permissible.
See, e.g., United States v. City of Huntington,
I
The City of Cincinnati operates a stormwater management system, which is designed to control stormwater runoff within the city. A city ordinance provides for a “storm drainage service charge” to be imposed on property owners within the city in order to pay the expenses of the stormwater management system. The amount of the assessment against each property owner is a function of the size of the property and its “intensity of development.” The general goal of the assessment formula is to impose higher assessments on properties that are expected to produce more stormwater runoff, such as commercial or industrial properties, and to impose lower assessments on properties that are expected to produce less stormwater runoff, such as residential or undeveloped properties. Not all of the distinctions in the rates of assessment can be accounted for by the expected amount of stormwater runoff from particular kinds of properties, however. As counsel for the city confirmed at oral argument, some distinctions among the assessment levels are based on a decision that certain kinds of properties, such as churches, should be subject to lower assessments.
The property owner in this case is a federal entity, the National Institute of Occupational Safety and Health (NIOSH), which operates a facility within the City of Cincinnati. The city contends that NIOSH owes more than $60,000 in storm drainage service charges. NIOSH has declined to pay the assessments, contending that the storm drainage service charge amounts to an unconstitutional tax on a federal entity. The city filed suit in the Court of Federal Claims to recover the assessed charges, arguing that the storm drainage charge is not a tax, but a charge for services that the United States, like any other user of city services, is required to pay.
The Court of Federal Claims dismissed the complaint for failure to state a claim upon which relief could be granted. In a thorough opinion, the court noted that the federal government can properly be charged for services that it purchases from local governmental entities, such as water or other utility services. The court held, however, that the storm drainage charge, which was imposed *1377 on all property owners within the city and was not the product of a voluntary purchase decision by the federal government, constitutes a tax, not a fee for services, and therefore could not be exacted from a federal entity such as NIOSH. The city appeals from that decision.

The Court of Federal Claims has jurisdiction “to render judgment upon any claim against the United States founded either upon the Constitution, or any Act of Congress or any regulation of an executive department, or upon any express or implied contract with the United States, or for liquidated or unliquidated damages in cases not sounding in tort.” 28 U.S.C. § 1491(a)(1). The trial court understood the city to be basing its invocation of jurisdiction on an implied-in-fact contract between the city and the United States, and the city confirmed at oral argument that it was basing its claim of jurisdiction on that ground. As the Court of Federal Claims explained, the invocation of the implied contract theory is sufficient in this case to set forth a basis for subject-matter jurisdiction, because the city has made a non-frivolous assertion of an implied contract with the United States.
See Trauma, Serv. Group v. United States,
An implied-in-fact contract is one “founded upon a meeting of the minds, which, although not embodied in an express contract, is inferred, as a fact, from conduct of the parties showing, in the light of the surrounding circumstances, their tacit understanding.”
Baltimore & Ohio R.R. Co. v. United States, 261
U.S. 592, 597,
The relationship between the city and NIOSH with respect to the storm drainage service charge did not result in an implied-in-fact contract. The storm drainage
service
charge was not imposed as a result of a consensual arrangement between the city and the United States, as would be true in the case of a voluntary purchase of utilities or other services. Instead, the stormwater drainage service charge was an assessment imposed on the United States involuntarily, by virtue of its status as a property owner. While the United States may be said to be a
*1378
beneficiary of the storm drainage services provided by the city, it was not offered the opportunity to choose whether to accept those benefits, and it cannot be said to have taken any action (other than not moving out of Cincinnati when the charges were assessed) to indicate its willingness to pay the charges. Under these circumstances, we are unable to discern the basis for an implied-in-fact contract in which the United States has voluntarily undertaken certain obligations that the Court of Federal Claims is empowered to enforce.
See, e.g., Midcoast Aviation, Inc. v. General Elec. Credit Corp.,
We part company with the trial court’s analysis in one respect, however. The trial court regarded the question whether there was an implied-in-fact contract between the city and the United States to be essentially the same question as whether the storm drainage service charge was a permissible fee for services or an impermissible tax. We disagree that the two inquiries are necessarily the same. As we have stated above, the involuntary nature of the storm drainage service charge is dispositive of the former inquiry: There can be no implied-in-fact contract without voluntary acceptance of the city’s services. The involuntary nature of the charge, however, is not dispositive of the latter inquiry. There may be some instances in which a municipal assessment is involuntarily imposed but would nonetheless be considered a permissible fee for services rather than an impermissible tax. Our decision in this ease does not answer that question and thus we do not hold that Cincinnati’s storm drainage service charge is a tax that cannot constitutionally be imposed on a federal entity. What we do hold is that the complaint, which was based on a theory of implied-in-fact contract, fails to provide any basis for concluding that there was an implied-in-fact contract between the city and the United States. The complaint therefore fails to state a claim upon which the Court of Federal Claims is empowered to grant relief.
AFFIRMED.
