The Case For Consumer-Based Use Tax Enforcement, David Gamage, Adam Thimmesch, Darien Shanske

Articles by Maurer Faculty

This essay argues that state governments’ current focus on getting vendors to collect their sales and use taxes is insufficient, especially in regard to e-commerce transactions. If state governments want their use taxes to serve as effective and lawful backstops to their sales taxes—as state governments claim is their goal—then states must also focus on the consumer side of the use-tax equation. This essay explains that both economic and rule of law considerations make it imperative for state governments to better enforce their sales and use taxes with respect to consumer taxpayers.

Consumer-Based Use Tax Enforcement And Taxpayer Compliance, David Gamage, Adam Thimmesch, Darien Shanske

Articles by Maurer Faculty

This essay explains how current state government approaches to use-tax enforcement undermine tax morale and taxpayer compliance. This essay further argues that these threats to tax morale and taxpayer compliance will become even more severe as many states are moving toward adopting notice and reporting statutes for their sales and use taxes.

A State-Level Carbon Tax With Border Adjustments, David Gamage, Darien Shanske

Articles by Maurer Faculty

This essay develops three new doctrinal arguments in support of the conclusion that a state-level carbon tax with border adjustments should be permissible under the dormant commerce clause. This essay builds on our prior work to argue against the view that a single state cannot (practically) impose a significant carbon tax due to the claim that border tax adjustments are Constitutionally impermissible. By demonstrating how a state government could implement a carbon tax with border tax adjustments in a Constitutionally permissible fashion, this essay shows that levying a carbon tax is a realistic and practical option for U.S. state governments. …

Why A State-Level Carbon Tax Can Include Border Adjustments, David Gamage, Darien Shanske

Articles by Maurer Faculty

This is our third in a series of articles considering taxation and greenhouse gas mitigation. To date, all state-level attempts to mitigate greenhouse gas emissions by placing a price on carbon have involved cap-and-trade regimes. In our previous two articles, we considered how importing tax features into a cap and- trade regime could ease distributive concerns and also make cap-and-trade regimes more efficient.

The American Health Care Act Would Toss The States A Hot Potato, David Gamage, Darien Shanske

Articles by Maurer Faculty

This essay explains how the American Health Care Act (AHCA) – the House Republicans’ proposed replacement for Obamacare – would toss a hot potato to state governments. Were the AHCA to be enacted into law, state governments would need to act promptly if they are to save individual insurance markets within their states. This essay explains measures that state governments might take to respond to this threat.

A New Theory Of Equitable Apportionment, David Gamage, Darien Shanske

Articles by Maurer Faculty

This essay analyzes the purpose of the equitable apportionment doctrine in state and local tax jurisprudence, arguing that the doctrine remains coherent in the context of single-sales-factor apportionment regimes.

Tax Cannibalization And Fiscal Federalism In The United States, David Gamage, Darien Shanske

Articles by Maurer Faculty

We began this project pondering a riddle. Most state governments have adopted what we-and many others-view as clearly suboptimal tax policies, especially in regard to the taxation of corporate income and capital gains. Yet, with the notable exception of those who oppose progressivity and the taxation of capital, state-level tax policymakers have had remarkably little appetite for reform.

This Article provides one major explanation for this riddle by identifying and demonstrating a phenomenon that we label as "tax cannibalization." We argue that flawed state-level tax policies derive in part from perverse incentives inadvertently created by the federal government.
