1. Introduction
Wisconsin’s sales and use tax rules pose unique challenges for software companies, SaaS providers, and technology firms operating in the state. Wisconsin differentiates between computer hardware, prewritten (canned) software, and custom software based on both the method of delivery and the degree of customization involved. The tax treatment of software and technology-related services in Wisconsin hinges on several factors, making the compliance landscape complex for businesses operating in this space.
