As it heads into the final weeks of its session, Congress is considering various bills that would restrict or expand states’ taxing authority. Almost every business in the country would be affected by at least some of these bills. While some of these bills have progressed further than others, any could become law—particularly if bundled into legislation that Congress must, as a practical and political matter, pass before the session ends. Businesses thus have an opportunity to ask their Senators and Representatives to take action to rein in some of the problems with state and local taxes.
