Example 1: State A requires all nonresident corporations that qualify or register in State A to pay to the Secretary of State an annual license fee or tax for the privilege of doing business in the state regardless of whether the privilege is in fact exercised. The amount paid is determined according to the total authorized capital stock of the corporation; the rates are progressively higher by bracketed amounts. The statute sets a minimum fee of $50 and a maximum fee of $500. Failure to pay the tax bars a corporation from using the state courts for enforcement of its rights. State A also imposes a corporation income tax. Nonresident Corporation X is qualified in State A and pays the required fee to the Secretary of State but does not carry on any business activity in State A (although it may use the courts of State A). Corporation X is not "taxable" in State A.
Example 2: The facts are the same as example one except that Corporation X is subject to and pays the corporation income tax. Payment is prima facie evidence that Corporation X is "subject to" the net income tax of State A and is "taxable" in State A.
Example 3: State B requires all nonresident corporations qualified or registered in State B to pay to the Secretary of State an annual permit fee or tax for doing business in the state. The base of the fee or tax is the sum of outstanding capital stock, and surplus and undivided profits. The fee or tax base attributable to State B is determined by a three-factor apportionment formula. Nonresident Corporation X, which operates a plant in State B, pays the required fee or tax to the Secretary of State. Corporation X is "taxable" in State B.
Example 4: State A has a corporation franchise tax measured by net income for the privilege of doing business in that state. Corporation X files a return based on its business activity in the state but the amount of computed liability is less than the minimum tax. Corporation X pays the minimum tax. Corporation X is subject to State A's corporation franchise tax.
