There is strong evidence that decisions of firms to locate, expand, and remain in particular states are heavily influenced by state policies including state and local tax levels. Firms planning to establish new plants or contemplating moves routinely solicit competitive offers from states. There are many examples of firms relocating or deciding to put their new plants in different states because of home-state taxes they consider too high.
Nearly all states respond to these solicitations for offers to draw new plants, often with tax concessions tailored to the soliciting firm. But offering such concessions only to firms considering relocation produces criticisms of state officials for not pursuing even-handed policies. More important, it induces all footloose firms to consider moves if for no other reason than to induce concessions from home states.
