State corporate income tax reform is gathering momentum in 2007, as more and more states are considering adopting an important corporate tax reform: combined reporting. Governors in New York, Iowa and Pennsylvania have already proposed this important loophole-closing reform, and newly elected Massachusetts Governor Deval Patrick is sending signals that he may follow in their footsteps. Meanwhile, a new paper by the Center on Budget and Policy Priorities' Michael Mazerov gives the lowdown on an equally important corporate tax reform that could productively be adopted by every state with a corporate tax: company-specific disclosure of taxes paid (or not paid). Mazerov's paper includes model legislation for use in any state seeking to shed more light on corporate tax avoidance.
