As many in the construction business know, you go where the work is. That often means traveling significant distances in and out of other cities, counties, and states. When that happens, the rules of contract, business, and taxes can change quite a bit. A contractor who is unfamiliar with multistate tax differences can get into trouble quickly. To make matters worse, state governments can be aggressive in identifying out of state contractors who might be potential taxpayers. Multistate tax issues can be expensive when your bid proposals or budgets fail to take into account these potential taxes.
