The reporting requirements for corporations operating in multiple states vary from state to state. Some states require separate return reporting while others permit or require the taxpayer to report income on a combined or consolidated basis. The type of filing mandated by a particular state can effect both the taxable income calculation and apportionment percentage in that state.

States that employ separate entity reporting require each corporation with sufficient nexus or business connections with that state to file its own corporate income tax return. Separate return filing is required even where the corporation is included in a consolidated return for federal income tax purpose. A return filed by a corporation in a separate return state generally reflects the corporation's total income or loss (after various state additions and subtractions) apportioned to such state pursuant to that state’s apportionment methodology.

Many states require or permit the filing of a consolidated or combined state income tax return where there are two or more affiliated corporations and each included corporations has nexus in the state. A state may require consolidation on either pre- or post-apportionment basis. If consolidation is on a pre-apportionment basis, the incomes of the corporations are combined and apportioned to the state using a single formula that includes the factors of all the entities. Conversely, if consolidation is on a post-apportionment basis, each corporation computes income separately and apportions the income to the state using a formula that includes only its factors. The resulting state taxable income amounts for all the corporations are then combined and reported together.
Some states require combined reporting where two or more separate businesses comprise a unitary business. Factors determining whether two businesses comprise a unitary business include whether the business activities are in the same general line, the existence of vertical integration and the existence of strong centralized management. Under this method, the combined taxable income of all members of a unitary group of businesses is computed and then apportioned among the group members based on apportionment percentages that reflect the combined operations of the unitary group. A member of the group that has nexus with a particular state then reports its share of the total income of the unitary group apportioned to such state on either a separate return or a combined report reflecting the operations of all group members having nexus with the state. The key difference between combined reporting and consolidated reporting is that, under combined reporting, the income apportioned to a state may include income of members of the unitary group that do not have nexus with that state.
