Executive Education Series Webinar
Webinar: Source Your Sales - A Multi-State Primer for Apportionment in Service

Service businesses that transact business across state lines and nationally are subject to state income taxes in many jurisdictions. The tax laws for each state are different, including the manner in which states determine the location of sales for apportionment purposes. Service businesses must contend with varying rules to determine the state to which sales revenues should be assigned.

This webinar will examine the common approaches utilized by state taxing jurisdictions to source service revenue in order to provide an overview of the principles involved.

Learning Objectives

After completing this course you will be able to:

  • List the varying approaches states use to source in-state service revenues
  • Describe the basic characteristics of the "cost of performance" method used by states to source service revenues
  • Describe the "market sourcing" standard used by states to source service revenues
  • Explain nuances in applying each of these methods across multiple states
