Significant changes in how businesses operate and consumers shop has caused a desperate search for revenue by most states. Internet commerce defies taxation under traditional concepts of nexus and situs. States have been expanding their view of nexus, especially for sales taxes. On June 21, 2018, the U.S. Supreme Court decided in Wayfair that physical presence is not required for sales tax nexus by overruling the Quill and National Bellas Hess decisions. This comes on the heels of Colorado's victory in the 10th Circuit
to require interstate businesses who did not collect sales taxes to instead report to the state "to assist the state in collecting use tax from in-state purchasers." These decisions, plus recent trends in state legislation and merging nexus standards for taxing sales and income, are blurring the landscape for many businesses. This change in fundamentals from a "presence-based" tax system to an "economic opportunity-based" tax structure requires CPAs to understand state and local tax issues. Businesses need to consider restructuring themselves to minimize the multi-state tax burden. This program explains and illustrates how to avoid becoming subject to excessive state taxation-and who knows, Congress might even pass legislation that has been proposed for almost 30 years!
