Sales Tax by State: Marketplace Facilitator Laws Explained

by Lizzy Greenburg

A marketplace facilitator is a business or organization that contracts with third parties to sell goods and services on its platform and facilitates retail sales of at least $250,000 during the prior 12-month period. It enables these sales by listing the products, taking the payments, collecting receipts, and in some cases assisting in shipment. When we refer to marketplace facilitator laws, we’re talking about legislation surrounding the sales tax responsibilities of these facilitators. 

Recently, several states have created legislation that requires marketplace facilitators to collect and remit sales tax on behalf of their third-party sellers’ transactions, including Alabama, Connecticut, Iowa, Minnesota, New Jersey,  Oklahoma,  Pennsylvania, and Washington. These laws benefit the states because they can collect more sales tax from fewer entities, which results in simpler compliance for the states. For sellers, the benefit lies in having sales tax for certain transactions handled by the facilitator. But in many cases, it’s not as simple as it may seem.

The Reasoning Behind These Laws

Marketplace facilitator laws grew from the idea that a state could collect all of the required sales tax from one entity rather than from hundreds of thousands of smaller companies. Let’s use Amazon as an example. Before these types of tax laws came into effect, each of the third-party sellers was responsible for collecting and remitting their own sales tax.

So if a third-party seller on Amazon didn’t have nexus (triggered by a physical location, employee staff, store inventory, or reach a certain amount or number of transactions) then it didn’t have to collect sales tax for sales in that state. And the state then missed that portion of revenue.

And even if a seller did have nexus there, if the seller chose not to follow the law, the state then spends significant time and resources to go after that seller, along with any other businesses that are non-compliant. That’s a lot of time and money to get their sales tax revenue. 

By placing the onus of sales tax on the facilitator (rather than the seller), these laws enable the states to force compliance across the entire state, and it dramatically reduces the cost of compliance for the states to claim their revenue.

What Sellers Need to Know

For sellers, marketplace facilitator laws mean that your facilitator will handle collecting and remitting sales taxes on behalf of your sales in states where your marketplace is compliant.

Another concern for sellers is whether a seller should keep their sales tax permits current if they are dealing with a state that imposes marketplace facilitator laws. The general consensus is yes. Remember, a facilitator will only handle the sales tax on transactions sold through its platform.

So, if Amazon is collecting sales tax on your behalf in Washington, but you are located in Washington and you sell items through your business website, too, you still need to collect, remit, and file  in the state on your own. To do that, you have to have current license or permit. And in most states, if you don’t do any sales outside of those with the facilitator, you’re required you to file a simple “zero return” saying so, or register for non-reporting sales tax status. 

But, it’s imperative that you as the seller arm yourself with all of the relevant information about possible marketplace facilitator laws. Below we’ll share all of the information that we know on which states currently impose these laws and the facts you need to know to stay up-to-date.

How to file your return when marketplace tax is collected

If your state return includes sales to customers in states with Marketplace Facilitator laws, TaxJar’s Reports (and TaxJar’s AutoFile) will assume that your marketplace has remitted all collected taxes associated with such sales on your behalf and will adjust your returns accordingly.  You can read more about how TaxJar handles this tax in our help center.

Every Marketplace Facilitator Law, by State

Important to note: This area of law is changing rapidly. While we strive to keep this post up-to-date, please use it as a guideline only and consult with a sales tax expert should you have specific questions as to how economic nexus applies to your business.


The Alabama law states that marketplace facilitators with marketplace sales over $250,000 must collect sales tax by or on behalf of its third-party sellers.

Additionally, remote sellers who exceed the economic nexus rule’s $250,000 small seller exception should register for the Alabama Simplified Sellers Use Tax Program (SSUT) and begin collecting no later than October 1, 2018.
