The principal issue in this case is whether General Motors Corporation and its subsidiaries have the right to file consolidated Missouri income tax returns for the years 1990, 1991, and 1992 pursuant to section 143.431.3(1), RSMo 1994. 1 Because construction of the revenue laws of the state is involved, this Court has exclusive appellate jurisdiction. Mo. Const, art. V, sec. 3. This Court reverses the decision of the Administrative Hearing Commission and remands for further proceedings, finding that section 143.431.3(1) violates the United States Constitution, article I, section 8, in that it discriminates against interstate commerce.
General Motors Corporation (GM) is a Delaware Corporation domiciled in Detroit, Michigan. GM is parent to numerous subsidiaries. GM and its subsidiaries constitute GM Group, which engages in manufacturing automobiles, trucks, component parts, and accessories. GM Group is also involved in the financing of those products and in insurance and business management systems. GM and some of its subsidiaries conducted business in Missouri from 1990 through 1992.
GM Group, as an affiliated group of corporations, filed federal consolidated income tax returns for 1990, 1991, and 1992. Approximately 300 subsidiaries were part of the affiliated group. GM Group also filed Missouri consolidated income tax returns in 1990, 1991, and 1992. GM Group conducted substantial business in Missouri from 1990 *563 through 1992. It had approximately $1.3 billion in property, $300 million in payroll, and $2.3 billion in gross receipts in Missouri for each of the three years. Because of its sizable commercial activities in other states, however, GM Group derived less than two percent of its income from sources within Missouri for each of the three years. On all three of its Missouri consolidated returns, GM Group reported zero tax liability. In 1990 and 1991, GM Group requested refunds in the amount of $3,651,703 and $1,172,400 respectively. GM Group did not claim a refund for 1992.
The Director of Revenue concluded that GM Group was not entitled to file consolidated returns for 1990,1991, and 1992 because it did not derive at least fifty percent of its income from sources within Missouri pursuant to section 143.431.3(1). The director denied GM Group’s refund claims for 1990 and 1991. The director further issued a notice of deficiency against GM in the amount of $12,-533,176 for 1992.
GM Group appealed to the Administrative Hearing Commission, (AHC), claiming that section 143.431.3(1) is unconstitutional because it violates the Commerce Clause,
U.S. Const,
art. I, sec. 8; the Due Process Clause,
U.S. Const,
amends. V and XIV; the Equal Protection Clause,
U.S. Const.
amends. V and XIV; the Equal Rights and Opportunities Clause,
Mo. Const,
art. I, sec. 2; and the Uniformity Clause,
Mo. Const.
art. X, sec. 3. The AHC upheld the director’s determination that GM Group did not meet the statutory requirements to file a Missouri consolidated income tax return in that it did not derive fifty percent of its income from sources within Missouri. Because GM Group did not meet the requirements for filing consolidated returns, it was not entitled to refunds for 1990 and 1991. The AHC further held that GM was not liable for Missouri income tax for 1992. The AHC did not reach the constitutional questions because it is without authority to decide constitutional issues.
State Tax Comm’n v. Administrative Hearing Comm’n,
Missouri law permits the filing of a consolidated income tax return by an affiliated group of corporations under the conditions specified in section 143.431.3(1), which provides in pertinent part:
If an affiliated group of corporations files a consolidated income tax return for the taxable year for federal income tax purposes and fifty percent or more of its income is derived from sources within this state as determined in accordance with section 143.451, then it may elect to file a Missouri consolidated income tax return....
The essential purpose of allowing corporations to file a consolidated return is to permit affiliated corporations, which may be separately incorporated for various business reasons, to be treated as if they were one corporation.
Mid-America Television Co. v. State Tax Comm’n,
GM Group contends, among other arguments, that section 143.431.3(1) violates the Commerce Clause of the United States Constitution because the threshold requirement that an affiliated group derive fifty percent of its income from sources within Missouri discriminates against interstate commerce. GM Group claims that it is being denied specific tax benefits because of GM Group’s corporate form and the geographic location of the group’s business activities. Under section 143.431.3(1), only business groups that perform the majority of their business activities in Missouri may elect to file a Missouri consolidated income tax re *564 turn. GM Group’s Commerce Clause claim is dispositive.
In recent years, the United States Supreme Court has addressed challenges under the Commerce Clause that provide guidance in resolving the present case. In
American Trucking Ass’n, Inc. v. Scheiner,
In
Camps Newfound/Owatonna, Inc. v. Town of Harrison,
It is not necessary to look beyond the text of this statute to determine that it discriminates against interstate commerce. The Maine law expressly distinguishes between entities that serve a principally interstate clientele and those that primarily serve an intrastate market, singling out camps that serve mostly in-staters for beneficial tax treatment, and penalizing those camps that do a principally interstate business. As a practical matter, the statute encourages affected entities to limit their out-of-state clientele, and penalizes the principally nonresident customers of businesses catering to a primarily interstate market.

A reading of the foregoing cases reflects the guiding principles for determining whether a statute discriminates against interstate commerce. State laws that facially discriminate against interstate commerce are virtually
per se
unconstitutional.
Camps Newfound/Owatonna,
Applying these principles to the fifty-percent threshold requirement set forth in
*566
section 143.431.3(1) dictates a determination that the requirement facially discriminates against interstate commerce. An affiliated group must derive the majority of its income from within the state of Missouri before it may elect to file a Missouri consolidated income tax return. The statute expressly distinguishes between affiliated groups that perform the majority of their business activities in Missouri and groups that perform the majority of their business activities out of state.
See Camps Newfound/Owatonna,
This Court has not undertaken the foregoing analysis without being cognizant of the requirements to presume the validity of a statute unless it clearly contravenes a constitutional provision,
Mahoney v. Doerhoff Surgical Servs., Inc.,
The director argues that this Court considered and rejected an argument identical to GM Group’s argument that the fifty-percent threshold requirement of section 143.431.3(1) discriminates against interstate commerce in
Williams Co., Inc. v. Director of Revenue,
Williams
can no longer be cited as authority for the constitutionality of section 143.431.3(1). This Court’s reasoning in
Williams
preceded the United States Supreme Court’s decision in
Kraft Gen. Foods.
As noted above, the Court in
Kraft Gen. Foods
rejected the argument that a statute that facially discriminates against interstate commerce can be rendered constitutionally valid by showing that the taxpayer could have avoided the adverse consequences of the statute by reorganizing its business or changing its domicile.
The director also claims that because section 143.431.3(1) neither imposes a tax nor grants a tax credit, .the statute is constitutionally valid. Imposing a tax and granting a tax credit are not the exclusive means of discriminating against interstate commerce. The form by which a state erects barriers to commerce has no effect on the determination of whether discrimination exists.
West Lynn Creamery, Inc.,
The director places great emphasis on the fact that section 143.431.3(1) properly apportions Missouri taxable income. The director claims that because Missouri is constitutionally required to tax only the income that derives from business activities having a nexus with Missouri, the state may condition the right to file a consolidated return on whether the consolidated group has a nexus with the state.
A determination that a state’s method of apportionment is constitutionally sound does not foreclose a determination of whether the state’s tax scheme discriminates against interstate commerce.
Westinghouse Elec. Corp.,
Finally, the director argues that the fifty-percent threshold requirement in section 143.431.3(1) passes the internal consistency test. The internal consistency test involves a determination of whether a state tax would impermissibly interfere with free trade if every jurisdiction enacted similar legislation.
American Trucking Ass’n,
The director’s argument fails to acknowledge that the portion of section 143.431.3(1) that discriminates against interstate commerce is the fifty-percent threshold requirement rather than the system of apportionment. If every state required affiliated groups to conduct a majority of their business within the state before the groups could qualify to file consolidated income tax returns, there would be interference with free trade. Affiliated groups would be unable to offset profits collectively earned by member corporations with the collective losses of the member corporations. The groups would not have the benefit of decreased tax liability or the administrative benefit of filing a single consolidated income tax return. If all states applied the fifty-percent threshold requirement, business groups would be encouraged *568 to perform the majority of their business within a single state and would be penalized for engaging in free trade.
This Court holds that to the extent that section 143.481.3(1) requires an affiliated group to derive at least fifty percent of its income from sources within Missouri as a basis for filing a Missouri consolidated income tax return, section 143.431.3(1) violates the Commerce Clause of the United States Constitution, article I, section 8.
It remains to determine whether the discriminatory portion of section 143.431.3(1) may be severed from the remainder of the statute. All statutes should be upheld to the fullest extent possible. Associated In
dust. of Missouri v. Director of Revenue,
The provisions of every statute are severa-ble. If any provision of a statute is found ... to be unconstitutional, the remaining provisions of the statute are valid unless the court finds the valid provisions of the statute are so essentially and inseparably connected with, and so dependant upon, the void provision that it cannot be presumed that the legislature would have enacted the valid provisions without the void one....
The legislature is presumed to be familiar with section 1.140 and to have intended that this Court give effect to the portions of the statute that are constitutionally valid.
Akin,
The fifty-percent threshold requirement can be severed from section 143.431.3(1) without invalidating the remainder of the statute. As discussed above, section 143.431.3(1) contains two requirements that an affiliated group must meet before it qualifies to file a Missouri consolidated income tax return. The group must file a federal consolidated tax return and must derive at least fifty percent of its income from sources within Missouri. The two requirements enumerated in section 143.431.3(1) are not inseparably connected, nor are they so dependent upon each other that it cannot be presumed that the legislature would not have enacted section 143.431.3(1) without the fifty-percent requirement.
Akin,
If an affiliated group of corporations files a consolidated income tax return for the taxable year for federal income tax purposes and-fifty- percent or more of its income is derived- from-sources within this state as determined-in-.accordance with section ■143:451, then it may elect to file a Missouri consolidated income tax return....
Once the invalid provision is severed from the statute, an affiliated group will be required to file a federal consolidated income tax return before the group will qualify to file a Missouri consolidated return.
The fifty-percent threshold requirement of section 143.431.3(1) violates the Commerce Clause of the United States Constitution, article I, section 8, in that it discriminates against interstate commerce. The fifty-percent requirement of section 143.431.3(1) is ordered severed. GM Group is authorized to file Missouri consolidated income tax returns for 1990,1991, and 1992.
The decision is reversed and remanded for further proceedings in accordance with this opinion.
