States Should Conform to GILTI, Part 3: Elevator Pitch and Q & A

Document Type


Publication Date



This essay argues that the states should conform to the post-2017 federal tax law's provision for Global Intangible Low-Taxed Income (or “GILTI”). This essay is directed at state legislators and their staffs and presents the argument as succinctly as possible.

Our argument can be summarized in three sentences. First, states should conform to GILTI because there is significant evidence that profit shifting is substantially eroding their corporate tax bases. Second, GILTI is a tool for identifying shifted profits. Third, there are many legally and analytically sound ways to apportion GILTI income to a state.

We also - briefly - counter the standard objections to state conformity with GILTI.
