Almost all states tax corporate income through corporate income or franchise taxes. The tax rates range from 1 percent to 12 percent. The taxable income computations for state purposes may differ from the computation for federal purposes, especially regarding the accelerated cost recovery deductions. For a state to tax a corporation, two tests must be met:

  • There must be a minimal connection between corporate activities and the state (the “nexus test”), and
  • The income attributable to the taxing state must be rationally related to values connected with the taxing state (the “rational relationship test”).

Once it is determined that apportionment of income to the state is proper, apportionment generally follows a three-factor formula based on percentages of worldwide sales, payroll and property attributable to the state. These percentages are averaged to arrive at an apportionment factor applied to the corporation's worldwide income. In certain cases, a foreign corporation may be permitted to separately account for the income taxable in the particular state. Certain states may impose capital or net worth taxes in lieu of or in addition to income taxes. Some cities (e.g., New York City) also impose corporate income taxes.

While most states tax each corporation separately, several states (e.g., California) employ the unitary method and tax an affiliated group of corporations not only on income from its purely local operations but instead on a portion of its entire income, to the extent that the affiliated group operates a unitary business. Several factors are considered in determining whether there is a unitary business, including functional integration, centralization of management, and economies of scale. Although the unitary method has been applied to the worldwide activities of an affiliated group of corporations, most states using this method now limit its application to the US activities of an affiliated group.

Sales and Use Tax

Forty-five states and more than 7,000 local jurisdictions impose sales and use taxes. When doing business with US customers, neglecting or not knowing the applicable sales and use tax rules can be costly.

Complying with sales and use tax laws is sometimes complex. In most states, compliance is facilitated by filing a single tax return that covers the state and all local jurisdiction taxes. In some states, local sales and use taxes are administered by local authorities that require additional local tax filings. Filing sales and use tax returns may be obligatory or prudent even if no tax is due.

A Canadian company with a minimal physical presence in a state may have sales and use tax compliance obligations. The in-state presence of an out-of-state company’s property, employees, independent agents or representatives can create a filing obligation. For example, a Halifax food processor that engages an independent sales representative to solicit sales to supermarkets in Pennsylvania must comply with Pennsylvania sales and use tax rules.

Determining whether a state’s sales and use tax laws apply is critical. The answer is relatively obvious when a sale takes place and the purchaser takes possession at the seller’s storefront. An out-of-state seller should generally consider the tax laws in effect at the destination where goods are shipped.

Use taxes generally apply where sales tax was not paid to the “use” state at the time of purchase. Assume a California resident purchases a taxable item in Nevada and pays Nevada sales tax at the point of purchase. On return to California, he or she must self-assess and remit use tax to California for the use of the item in California, although California may allow credit for the Nevada tax paid.
