A business selling through wholesale, retail, and ecommerce channels is exposed to state tax rules differently in each one — and a tax review that treats all revenue the same way will misstate the actual picture in at least one direction.
Why the channels diverge
- Wholesale sales are often exempt from sales tax collection when a valid resale certificate is on file — but the obligation to collect and maintain that documentation is real and frequently overlooked
- Retail and ecommerce sales are typically taxable at the point of sale, with rates and rules that vary by state and even by local jurisdiction
- Marketplace facilitator laws can shift the collection responsibility for certain ecommerce sales to the platform itself — but only for sales made through that platform, not your direct channels
Beyond sales tax: income tax apportionment
State income tax exposure is also channel-sensitive. How revenue is apportioned across states for income tax purposes can differ based on where sales occur, where inventory sits, and how each channel is structured — a separate question from sales tax collection, but one that compounds the same underlying complexity.
A channel-aware tax review — rather than a single company-wide assessment — is what catches exposure specific to one part of the business before it becomes a liability across all of it.
