Sales Tax Guide for Online Marketplace Providers

Online Marketplaces Sales Tax

This guide is for online sellers who have decided to create an online marketplace where multiple sellers can list and sell items. Handling sales tax can be tricky for online marketplace providers, so this guide will help you determine your options and how you should collect sales tax.

The info below is intended to serve as a guide. But, as always, when you have a tricky sales tax situation,  we recommend consulting with a sales and use tax expert for specific advice and guidance.

What is an online marketplace?

By the most basic definition, an online marketplace is a website where multiple sellers can list and sell their products.

eBay, Amazon (via FBA or MF) and Etsy are some of the most well-known online marketplaces, but they’re far from the only ones. If you look around you’ll find online marketplaces in all kinds of categories – like 1stDibs for furniture, RubyLane for collectibles, or Ecohabitude for eco-conscious products.

As a buyer, browsing a trusted or curated online marketplace is an easy way to cut through all the noise online and make a purchase. As a seller, selling on an online marketplace is a great way to get your items in front of a group of interested buyers. The marketplace often does a lot of the marketing and advertising heavy lifting so you can focus on selling your products. Everybody wins!

If all of this sales tax talk is indecipherable to you, I recommend checking out our Sales Tax 101 for Online Sellers Guide.

Sales Tax 101 for Online Marketplaces

Most tangible products are taxable in the U.S. and beyond, and that means that as an online marketplace provider, you need to decide how you’ll handle sales tax.

You have a few options:

Option 1: Be the “Seller of Record”

As the “seller of record” on your platform, you are responsible for all sales on your platform. That means you are also responsible for abiding by all sales tax laws and collecting and remitting sales tax. In this case your sellers will love you because you handle the administrative burden of sales tax for them.

But the downside is… you handle the administrative burden of sales tax. You’d have to figure out if you have sales tax nexus in each state (and your sellers would generally create nexus for you), and abide by each state’s sales tax rules and rates. Not to mention, you’d be required tor register for sales tax permits in each state, and to file sales tax returns in multiple states. This can become a tall order very quickly.

While this may sound like a huge hassle, it can be done. Jet.com, for example, is the seller of record for their 3rd party sellers. This means that anybody selling on the Jet.com platform does not have to worry about collecting and remitting sales tax. It’s up to you to decide how you want to handle sales tax on behalf of your sellers.

Option 2: Provide a Way for Your Marketplace Sellers to Collect Sales Tax

Probably the most popular option when dealing with sales tax on marketplaces is to provide your marketplace’s sellers with a way to collect sales tax on their own sales. If you currently sell on a platform like eBay, Amazon or Shopify then you are probably familiar with setting up your tax settings, collecting sales tax from customers and remitting the sales tax you collected to your state (or states) periodically. (If not, check out our Sales Tax 101 for eCommerce Sellers guide.)

If you go this route, you give your sellers a way to calculate and collect sales tax from buyers via your marketplace. The seller is responsible for setting up the sales tax collection settings correctly, registering to collect sales tax, and filing and remitting sales tax when it’s due.

If this is your strategy, you’ll need a sales tax engine to help your customers collect sales tax from their buyers. Skip down to “How to Collect Sales Tax on your Online Marketplace” for how TaxJar’s SmartCalcs sales tax API can make this simple.

Option 3: Do Nothing

Though we don’t recommend it, you can also opt to simply do nothing about sales tax. In this case, the sellers on your marketplace would have no good way to collect sales tax from their buyers. They would be stuck either paying sales tax due out of their profits, or trying to bill customers separately for sales tax. Neither tactic is ideal for your marketplace sellers, and creates a suboptimal selling experience on your marketplace.

However, if you’ve sent up your marketplace this way, or are selling on a marketplace that doesn’t allow you to collect sales tax, TaxJar has a feature that can help. TaxJar’s “Expected Sales Tax Due” report will tell you how much sales tax our tax engine thinks a seller should have collected.
