Shanske: How The States Can Tax Shifted Corporate Profits

Darien Shanske (UC-Davis), How the States Can Tax Shifted Corporate Profits: An Application of Strategic Conformity, 93 S. Cal. L. Rev. ___ (2020) (reviewed by Michelle Layser (Illinois) here): 

S Cal L RevThe combination of pandemic, recession and federal dysfunction has put severe fiscal strain on the states. Given the scale of the crisis and the essential nature of the services now being cut, it would be reasonable for states to contemplate inefficient — and even regressive — revenue-raising measures. Yet surely they should not start with such measures. They should start with making the efficient and progressive improvements to their revenue systems that they should have made anyway.

Improving the taxation of the profits of multinational corporations — the topic of this Article — represents a reform that would be efficient, progressive and relatively straightforward to administer. Not only would such a reform thus represent good tax policy, but it would raise significant revenue. And, if substantial revenue, efficiency, progressivity and administrability are not sufficiently motivating, then I will also add that it would be particularly appropriate to make these changes during the pandemic so as to raise revenue from those best able to pay during the current crisis.

To be sure, the argument that states can and should tax multinational corporations more has the whiff of paradox. After all, there is general consensus that no nation-state is currently taxing multinational corporations very effectively and, further, that subnational governments are in an even worse position to do so. This is because MNCs can exploit the mobility of capital even more easily between parts of the same country. Nevertheless, I will argue that the American states find themselves in a particularly strong position to do better at taxing MNCs and this is in part precisely because of the missteps made at the federal level.

The Tax Cuts and Jobs Act (“TCJA”), passed in December 2017, contained several provisions, including rules concerning Global Intangible Low-Taxed Income (or “GILTI”), that were meant to combat income stripping. The GILTI provision identifies foreign income likely to have been shifted out of the US and subjects it to US tax.

In this Article, I argue that the states should and can tax GILTI income. The basic policy argument is simple: states should not miss a chance to protect their corporate tax bases. The amount of revenue at stake is not trivial; it could be as high as $15 billion/year for the states as a whole or the equivalent of a 30% boost in corporate tax collections.
