This course, led by state tax attorneys from Hodgson Russ LLP, will explore the recent trends and developments in the interpretation and application of federal laws that impose limits on state taxation. These federal limitations, which include Public Law 86-272, the Internet Tax Freedom Act (ITFA), and Public Law 104-95, are currently being tested and challenged by various state revenue agencies. In today’s increasingly digital and national economy, it is therefore essential for all multistate taxpayers to know how to rely on these protections and how to resist state challenges where appropriate. This seminar will focus on the various state efforts to shrink federal protections and offer practical solutions for how multistate taxpayers should interpret and apply the protections as they exist today.
