If you or your business sells product on Amazon using the Fulfillment by Amazon (FBA) service, you are well into the multi-state sales tax mess ... even if you are not aware of it. You may be asking yourself:
Background
The old sales tax standard required you to collect and remit sales tax only in states that you have a physical presence (also known as physical nexus). The recent South Dakota vs. Wayfair, Inc. decision by the Supreme Court then legitimized the concept of economic nexus. This means your business could be required to collect and remit sales tax based on where you ship a product and not whether you ever set foot in a particular state (economic nexus).
The bigger mess
States were quick to jump on the bandwagon and actively identify Amazon, Ebay and Walmart sellers to demand sales tax for website sales. Some states, like California, got even more aggressive and decided that FBA sellers actually have physical presence because Amazon may put your product in a warehouse in their state. They got seller lists from Amazon and sent out threatening letters to small sellers demanding back sales tax, even though businesses have no way to retroactively collect the tax because the customers are Amazon customers.
Marketplace facilitator to the rescue?
To help address this mess and alleviate the need for small businesses to collect and remit sales tax forms to 50 states, many states acknowledged the problem and have passed what is called Marketplace Facilitator laws.
In short, it’s on the facilitator, NOT you. States with these laws require Amazon, Ebay and similar companies that facilitate sales for resellers to collect and remit sales tax on reseller Amazon activity. There are more than 30 states that have adapted these laws.
You DO NOT need to register your business to collect sales tax in states that have Market Facilitator legislation unless you are otherwise required to do so.
