We investigate how firms use differences in state income tax regimes to lower their state tax burdens. We develop a model that predicts that firms' state effective tax rates first decrease then increase as a function of the number of states in which they file returns. Using firm-level data, we...

"We document that simulated corporate marginal tax rates based on financial statement data (Shevlin 1990 and Graham 1996a) are highly correlated with simulated rates based on corporate tax return data. We provide algorithms that can be used to estimate the book or tax simulated rates when they...
