Interstate sales tax compliance challenges for businesses

Businesses face increasing complexity in managing interstate sales tax compliance due to evolving nexus standards. Following the South Dakota v. Wayfair decision, companies can trigger tax obligations in states where they have no physical presence based solely on revenue or transaction thresholds. This shift is particularly impactful for businesses utilizing ecommerce, marketplaces, and multiple payment channels.

In specific sectors like construction, tax obligations vary significantly based on the distinction between tangible materials and services. For instance, in Texas, tax treatment depends on contract structures: under lump-sum contracts, contractors are considered consumers and must pay tax on materials, whereas under separated contracts, they act as retailers who can use resale certificates but must collect tax from customers. Accounting firms are increasingly tasked with advising clients on assessing economic nexus and implementing automation to manage these multi-state requirements.
