The assignment to a state of a share of a multistate corporation's total net income is generally accomplished by processes known as allocation and apportionment and is the most deceptively simple concept in all of multistate income taxation.

The term "allocation" generally refers to the assignment of "nonbusiness income" to a particular state. In most states, "nonbusiness income" is considered to be income arising out of activity not related to the business of the corporation. For example, rental income derived by a manufacturing corporation from a parcel of out-of-state real estate unrelated to the manufacturing business generally would be treated as nonbusiness income and would be allocated in full to the state in which the property is located. Nonbusiness income generally is assigned to states on the basis of the location of the property or, if the property is intangible, on the basis of the taxpayer's commercial domicile.

In most states, the term "apportionment" refers to the assignment of a taxpayer's "business income" on the basis of a formula. "Business income" is that arising out of activity occurring in the regular course of a corporation's business. Typically, the formula used to apportion business income among states is based on the ratio of the taxpayer's activity within the taxing state to total activity.

Limited uniformity in the apportionment practices of the states creates the risk of overlapping taxes on interstate commerce. No legislation has been enacted on the federal level to ensure uniformity. The states have attempted to achieve a significant degree of uniformity on their own through the Uniform Division of Income for Tax Purposes Act (“UDIPTA”), with some states have adopted in total or in substantial part. A Multistate Tax Compact (“MTC”) requires states joining the compact to adopt the UDIPTA or offer it as an optional method. Most states participate in the MTC but their level of participation varies, resulting in considerable diversity in apportionment formulas.

Right to Apportionment

Before applying the apportionment rules, the taxpayer must consider whether or not it has the right to apportion its business income. Allocation and apportionment of net income under the UDITPA is a right of "any taxpayer having income from business activity which is taxable both within and without this State, other than activity as a financial organization or public utility or the rendering of purely personal services".3

For purposes of the UDITPA, "a taxpayer is taxable in another State if (1) in that State he is subject to a net income tax, a franchise tax measured by net income, a franchise tax for the privilege of doing business, or a corporate stock tax, or (2) that State has jurisdiction to subject the taxpayer to a net income tax regardless of whether, in fact, the State the does or does not do so".4

Thus, a taxpayer may apportion if it is actually subjected to one of the four taxes listed above or if its activities in another state are such that the state could constitutionally impose an income tax on the taxpayer, regardless of whether it in fact does so.

Regulations issued by the Multistate Tax Commission explain that the list of taxes that may make a taxpayer "subject to" a tax in another state is directed at income taxes or "other types of taxes which may be imposed as a substitute for an income tax".5

States that do not employ the UDITPA standard as a basis for determining whether a taxpayer has a right to apportion generally use "business activity" in another state as a test. Business activity in another state which may entitle a taxpayer to apportion its income include business "carried on," "done," "transacted," "conducted," and "engaged in”. The vagueness of the phrase has allowed some states to take a less stringent view than the UDIPTA rules.

Apportionment Formula

The UDIPTA apportionment formula is the apportionment percentage multiplied by total business income. The apportionment percentage is a total of in-state sales over total sales, in-state property over total property and in-state payroll over total payroll. In this formula, the three factors are given equal weight; however, some of the states use unequal weighting of the factors.

Sales Factor

The sales factor of the apportionment formula measures the extent of the taxpayer's sales activity in the taxing state. For purposes of assigning sales to a taxing state's sales factor numerator, "sales" (defined as all receipts) are categorized as either sales of tangible personal property and all other "sales".

Receipts from tangible personal property (both inventory and occasional sales of business assets) are assigned to the taxing state if the property is shipped or delivered to a purchaser within the state. If the taxpayer is not taxable in the state of the purchaser, the sale is assigned to the state where shipment originates (the "throwback rule”). There is also a throwback rule for all sales to the US government; such sales are to be assigned to the state of shipment even if the seller is taxable in the state of receipt.

Sales of property other than tangible personal property are assigned to the taxing state if the "income-producing activity" or a greater portion of it is performed in the taxing state. For example, receipts in the form of rent, royalties, interest or dividends if business income are assigned to the taxing state if most of the income-producing activity is performed in the state.

Property Factor

The property factor of the apportionment formula measures the extent of the taxpayer's use of property in the taxing state for the production of business income. The property factor is a fraction whose numerator is the average value of the taxpayer's real and personal property owned or rented and used within the state and whose denominator is the average value of all such property owned or rented and used during the tax period. Owned property is valued at its original cost (before depreciation); rented property is valued at eight times the net annual rental rate.

The MTC regulations limit the property factor to property used "in the regular course of the taxpayer's trade or business".6 The regulations exclude property used in connection with the production of nonbusiness income. Property used both in the business and in the production of nonbusiness income is only to the extent that the property is used in the regular course of the taxpayer's trade or business.

The term "real and tangible personal property" includes land, buildings, machinery, stock of goods, equipment and other real and tangible personal property but does not include coin or currency”.7 Additional examples of property that may be included in the property factor include construction in progress, partnership property and work in progress.

Payroll Factor

UDITPA defines the payroll factor as the total amount paid in the taxing state during the tax period by the taxpayer for compensation divided by total compensation paid everywhere during the same period.

MTC regulations limit the payroll factor to "the total amount paid by the taxpayer in the regular course of its trade or business for compensation during the tax period.” Under the MTC regulations, compensation paid for activities connected with the production of nonbusiness income is excluded from the factor.

Both UDITPA and the MTC regulations define "compensation" as wages, salaries, commissions and any other form of remuneration paid to employees for personal services. Amounts paid directly to employees are included in the payroll factor; these amounts include the value of board, rent, housing, lodging and other benefits or services furnished to employees that constitute income to the recipient under the IRC. The payroll factor includes compensation to employees who perform services entirely in states in which the taxpayer is immune from taxation.

UDITPA provides that the payroll factor is based on compensation "paid". The MTC regulations provide that the amount "paid" is determined on the basis of the taxpayer's accounting method. If a taxpayer has adopted the accrual method of accounting, compensation properly accrued is deemed to have been paid for purposes of the payroll factor.

The UDITPA establishes four tests for determining whether compensation is "paid in the state". If an employee's activities meet any one of the following tests, his or her compensation is included in the taxing state's payroll-factor numerator:

  1. All the individual's services are performed in the taxing state, or only incidental services are performed outside the taxing state.
  2. Some of the individual's services are performed in the taxing state, and the individual's base of operations is in the taxing state
  3. If there is no base of operations, some of the individual's activities are performed in the state, and the state is the place from which his or her work is directed or controlled.
  4. If there is no base of operations or place where the work is directed and controlled, some of the individual's services are performed in the taxing state, and the individual is a resident of the taxing state.

Apportionment Factors for Special Industries

Because the apportionment formula does not set forth the appropriate procedures for determining the apportionment factors for special industries, the MTC has issued special regulations on apportionment factors for construction contractors, airlines, railroads, trucking companies, television and radio broadcasting and publishers.

For example, under the MTC regulation for trucking companies, the three factors of property, payroll, and sales are used, except that mobile property, the interstate services of personnel, and sales revenue from interstate hauling are attributed to the state on the basis of mobile property miles occurring within and without the state.

Other Issues

The general apportionment method sometimes produces an unreasonable result for the taxpayer or tax administrator. If the allocation and apportionment provisions do not fairly represent the extent of the taxpayer's business activity in a state, the taxpayer may petition for or the tax administrator may require, in respect to all or any part of the taxpayer's business activity, if reasonable:

  • Separate accounting
  • The exclusion of any one or more of the factors
  • The inclusion of one or more additional factors that will fairly represent the taxpayer's business activity in the state
  • The employment of any other method to effect an equitable allocation and apportionment of the taxpayer's income.

The party must show through objective evidence, using appropriate comparisons, that the tax base attributed to the jurisdiction under the apportionment method exceeds statutorily or constitutionally permissible norms.
