In light of ever-present budget shortfalls in most states’ coffers, a go-to revenue-generating technique affecting all business owners is a “nexus” audit. The U.S. Supreme Court decision last summer in South Dakota v. Wayfair, 138 S.Ct. 2080 (2018), overturning the long-standing precedent in Quill Corp. v. North Dakota, 504 U.S. 298 (1992), has lengthened the states’ reach to audit an out-of-state business without regard to whether the business ever physically crossed the state’s borders.
