Determining if a business has "nexus" in a state is a significant tax question with answers that change regularly due to legislation, judicial decisions, and new ways of doing business. The ease of being a multistate company in today's e-commerce environment means more businesses face this question. As states search for tax revenues, state legislatures and tax agencies are earnestly looking for ways to find that a business has income and/or sales tax obligations in the state.
