State-by-state registration requirements for marketplace sellers

On June 21, 2018, the Supreme Court of the United States authorized states to tax remote sales based on the seller’s economic activity in the state, or economic nexus. More than 40 states, and counting, now have economic nexus laws on the books. 

Around the same time, states began requiring marketplace facilitators to collect and remit sales tax on behalf of their third-party sellers. Approximately 35 states (including D.C.), and counting, now have such marketplace facilitator laws on the books.

These two significant events have left many marketplace sellers wondering, “Do I need to register in a state if I exceed the economic nexus threshold, but all of my sales are via a marketplace that collects and remits on my behalf?"

Unfortunately, as is often the case with sales tax, the answer is: “It depends.”

Whether a marketplace seller needs to register with a state generally depends on certain circumstances, described below. Because this question really only comes into play when a state has both marketplace facilitator laws and economic nexus laws, we’ll only examine the states that have both laws in place. The effective dates below refer to the date marketplace facilitators are required to collect and remit tax on all marketplace sales.

Registration requirements generally vary based on how a marketplace seller makes sales in each state:

• Remote multichannel seller: You sell through a marketplace(s) and other channels into the state and have no physical presence in the state.
• Remote marketplace seller: You only sell through a marketplace(s) into the state and have no physical presence in the state. 
• In-state multichannel seller: You have a physical presence in the state and sell through a marketplace(s) and other channels in the state. 
• In-state marketplace seller: You have a physical presence in the state and only sell through a marketplace(s).

Bear in mind that although marketplace facilitator laws may relieve some marketplace sellers from certain sales tax collection obligations, marketplace sellers can have a physical presence — and an obligation to collect and remit sales or use tax — in states where their inventory is stored for sale. Marketplace facilitator laws don’t erase past tax liability.

The information provided below is based on state statutes and information from state tax departments available as of July 31, 2019. It is subject to change as tax officials work through and refine the policies. You should always consult directly with a trusted tax advisor or the taxing jurisdiction before deciding how to deal with sales and use tax compliance in a given state. For more information or assistance in determining your sales tax registration, collection, and remittance requirements, contact Avalara Professional Services.

Marketplace facilitator sales tax laws add another layer of complexity to sales and use tax compliance. They’re one more thing to track, and they typically don’t relieve sellers of all sales and use tax obligations.

You don’t have to negotiate them alone. Avalara offers tax compliance tools and resources specifically for online marketplace sellers.

Although we hope you’ll find the information helpful, this guide does not offer a substitute for professional legal or tax advice. If you have questions about your tax liability or concerns about compliance, please consult your qualified legal, tax, or accounting professional. This information was compiled in June 2019. Because states constantly update and amend their sales and use tax laws, see each state’s tax authority website for the most up-to-date and comprehensive information.
