Unique Local Compliance Challenges Post-Wayfair: Determining Economic Nexus, Exemptions, Constitutional Protections

Tuesday, May 7, 2024 | 1:00 pm EDT | 11:00 am MDT

This webinar will review the impact of the Wayfair decision on local tax collection systems. Our astute panel of SALT specialists will focus on the most complex local tax systems in specific states, including Alabama, Alaska, Arizona, California, Colorado, Louisiana and Texas.


Five years later, the U.S. Supreme Court decision South Dakota v. Wayfair Inc. continues to significantly impact state and local taxation. Post Wayfair, every state that assesses sales tax has implemented sales and transaction thresholds in light of the decision. Determining nexus standards by jurisdiction is an arduous process. Home rule states allow local authorities to set their own guidelines and collect sales tax separately from the state’s revenue department. These localities can and do establish economic nexus thresholds that differ from those of the state’s income tax division. Alaska, for example, does not impose a state income tax but does allow more than 100 local jurisdictions to impose and collect taxes, establishing their own guidelines and tax rates.

Understanding a company’s local tax burden is only the first step. Determining if specific exemptions apply to a business’ service or product and obtaining the exemption certificate can provide significant tax savings and avoid future complications. It is critical that multistate businesses and SALT advisers are familiar with the unique local compliance burdens within states and understand where problems may arise.

Listen as our experienced panel of state and local tax advisers outlines specific nuances of local taxes in specific states post-Wayfair.
