Dear Senator Mathewson and Representative Griffin:
This opinion is in response to your questions asking:
a. Are the pension benefits of federal civil service and military employees exempt from Missouri income tax based on the principles declared in Paul S. Davis v. Michigan Department of Treasury, 87-1020 (U.S. 3/28/89)?
b. Must the State of Missouri recognize timely income tax refund claims filed by federal civil service and military pensioners for the tax years 1985, 1986, 1987 and 1988?
In Paul S. Davis v. Michigan Department of Treasury, No. 87-1020 (U.S. March 28, 1989), the United States Supreme Court held that Michigan's tax scheme violated the principles of intergovernmental tax immunity by favoring retired state and local government employees over retired federal employees. The appellant, Paul S. Davis, a Michigan resident, was a former employee of the United States government. He received retirement benefits pursuant to the Civil Service Retirement Act. For the years 1979 through 1984, the appellant paid Michigan state income tax on his federal retirement benefits in accordance with Michigan law. Michigan law defined taxable income in a manner that excluded all retirement benefits received from the state or its political subdivisions but included most other forms of retirement benefits. As noted by the United States Supreme Court, the effect of this definition was that the retirement benefits of retired state employees were exempt from state taxation while the benefits received by retired federal employees were not.
In reaching its decision, the United States Supreme Court discussed the judicial doctrine of intergovernmental tax immunity as applied to attempts to impose federal income tax on state and local government employees and attempts to impose state income tax on federal employees. Prior to the adoption of the Public Salary Tax Act of 1939 by the United States Congress, salaries of most government employees, both state and federal, generally were thought to be exempt from taxation by another sovereign. Dissatisfied with the uncertain state of affairs due to judicial revision of the doctrine of intergovernmental tax immunity and concerned that considerations of fairness demanded equal tax treatment for state and federal employees, Congress decided to ensure that federal employees would not remain immune from state taxation at the same time that state government employees were required to pay federal income taxes. Thus, the Public Salary Tax Act of 1939 was passed, including what is now § 111 (
The United States consents to the taxation of pay or compensation for personal service as an officer or employee of the United States . . . by a duly constituted taxing authority having jurisdiction, if the taxation does not discriminate against the officer or employee because of the source of the pay or compensation.
In Davis, the United States Supreme Court placed great reliance upon the final clause of the section which contains an exception for state taxes that discriminate against federal employees on the basis of the source of their compensation. The Court concluded that Congress defined the scope of immunity retained in § 111 based upon the prior judicial doctrine barring taxes that operate so as to discriminate against the government or those with whom it deals. Accordingly, the Court found that the tax imposed upon Mr. Davis by the State of Michigan was barred by the doctrine of intergovernmental tax immunity because it discriminated against retired federal employees in favor of retired state and local employees.
In reaching its conclusions, the Court rejected the argument that retirement benefits do not constitute compensation for personal services as an officer or employee of the United States as set forth in § 111. The Court noted that the amount of benefits to be received in retirement is based and computed upon an individual's salary and years of service even though retirement pay is not actually distributed during the time an individual is working for the government. Therefore, the Court concluded that civil service retirement benefits are deferred compensation for past years of service rendered to the government and thereby fall squarely within the category of compensation for services rendered "as an officer or employee of the United States." Although Mr. Davis was a civil servant, the reasoning of the Court would apply equally to a retired member of the armed forces of the United States, who would also be an officer or employee of the United States as set forth in § 111.
After concluding that the Michigan income tax act violated principles of intergovernmental tax immunity by favoring retired state and local government employees over retired federal employees, the Court also discussed remedies. First of all, the court noted that the state had conceded that a refund was appropriate in the circumstances to the extent that Mr. Davis had paid taxes pursuant to the invalid tax scheme. However, the Court declined to issue prospective relief as requested by Mr. Davis because of its belief that the State of Michigan and the Michigan courts were in the best position to determine how to comply with the mandate of equal treatment. The Court noted that invalidation of Michigan's income tax law in its entirety would eliminate the constitutional violation but felt that such a drastic solution was not required in this case. Accordingly, the cause was then remanded to the Michigan courts for further proceedings in accordance with the United States Supreme Court's decision.
Like Michigan, Missouri exempts the retirement benefits of state and local employees from state income tax while imposing said tax on the benefits of federal retirees. Like Michigan, Missouri is subject to the doctrine of intergovernmental tax immunity and the pronouncements of the United States Supreme Court on that subject. The reasoning of the United States Supreme Court in Davis is clear. Under the principles announced by the United States Supreme Court in Davis, taxation of the retirement benefits of federal employees by the State of Missouri is discriminatory and invalid. Therefore, in answer to your first question, we conclude taxation of retirement benefits of federal civil service and military retirees under current Missouri income tax statutes is invalid.
Turning to your second question, Missouri law allows any taxpayer who has overpaid his income tax to file a claim for refund with the Director of Revenue. See Section
A reasonable construction of the terms "overpayment" and "erroneous" as used in section
136.035 includes the term "illegal" as seen from other interpretations by this Court, the plain meaning of the language and the definition in Black's Law Dictionary.The State of Missouri has thus consented to a refund of any overpayment, erroneous or illegal payment, which would include a tax declared unconstitutional, of any tax on intangible personal property by the terms of section
136.035 ; . . .
The reasoning of the Missouri Supreme Court in theCommunity Federal case is applicable to this situation.1 By enacting statutes allowing a refund for overpayment of Missouri income tax, the State of Missouri has consented to a refund of any overpayment, including a tax subsequently declared unconstitutional or invalid, if the taxpayers follow the proper procedures for applying for a refund. Section
CONCLUSION
It is the opinion of this office that (1) based on the principles stated in Paul S. Davis v. Michigan Department ofTreasury, No. 87-1020 (U.S. March 28, 1989), taxation of retirement benefits of federal civil service and military retirees under current Missouri income tax statutes is invalid, and (2) the State of Missouri must recognize timely income tax refund claims filed by federal civil service and military pensioners.
Very truly yours,
WILLIAM L. WEBSTER Attorney General
