Understanding Multi-State Taxation for Small and Medium Sized Businesses

Doing business across state lines brings a maze of tax obligations that can catch even experienced companies off guard. In this presentation, I explain how multi-state taxation works, including the rules that determine nexus, income apportionment, and filing obligations across different jurisdictions. You’ll learn the differences between physical nexus, economic nexus, and affiliate nexus, how states divide taxable income using apportionment formulas, and how to avoid double taxation or compliance penalties. I also address how remote work and digital sales have expanded state taxing authority since Wayfair v. South Dakota. Whether you operate a growing business, manage state filings, or advise clients, this presentation will help you understand how to comply with multi-state tax laws, protect against audits, and minimize your overall tax burden.
