The 2017 Tax Cut and Jobs Act reduced the US corporate tax rate and introduced provisions to curb profit shifting. We combine survey data, tax data, and firm financial statements to study the evolution of the geographical allocation of US firms' profits after the reform. The share of profits...

This paper examines how corporate taxation of multijurisdictional firms using formula apportionment affects the incentives faced by individual firms and individual states.

Alternatives to the current system of separate tax accounting, such as the proposed Common Consolidated Corporate Tax Base in Europe, would apportion a firm's worldwide profits using formulas based on the location of employment, capital or sales. This paper offers a new method of evaluating the...
