  • An employee or independent contractor present in the state
  • Goods in a warehouse
  • Services completed in the state
  • Computer software used by a third party in the state
  • Participating in trade or craft shows and festivals in the state for 15 days or more per year
  • Economic nexus (i.e. your sales or transactions into the state mean you are subject to the state’s economic nexus rule)
