Justia Massachusetts Supreme Court Opinion Summaries

Genentech, Inc. v. Commissioner of Revenue

By
Under Mass. Gen. Laws ch. 63, corporations that generate business income in the Commonwealth and other states must pay taxes on that income according to an apportionment formula that seeks to tax the corporation’s income generated in Massachusetts. For a “manufacturing corporation,” the statutory formula is based solely on the corporation’s sales. The Appellate Tax Board determined that Genentech, Inc., a Delaware corporation with a principal place of business in California that earns business income in the Commonwealth, qualified as a manufacturing corporation for the tax years 1998 through 2004. On appeal, Genentech appealed that determination, among other things. The Supreme Judicial Court affirmed, holding (1) Genentech qualified in each of the tax years at issue as a “manufacturing corporation” as defined in Mass. Gen. Laws ch. 63, 38(1)(1) and, under section 38(1)(2), was required to apportion its income under the single-factor formula using solely the statute’s sales factor; and (2) the Board properly rejected Genentech’s claim that application of the statute’s single-factor apportionment formula based on sales to the company violated the Commerce Clause of the federal Constitution.
