The Ultimate Guide to Ecommerce Sales Tax

Ecommerce sales tax is a type of consumption tax that online merchants collect from customers and then pass on to the government. Also referred to as online sales tax, it is charged as a percentage, though the specific amount changes depending on the merchant’s and customer’s locations.

It works a bit differently when selling online as opposed to selling in a physical store because you’re doing business in multiple states, so it’s important to get familiar with how ecommerce tax works and what you need to do to be compliant.

Luckily, most ecommerce platforms and online store builders, including Shopify and BigCommerce, automate sales tax collection based on your business information and the information customers enter at checkout, so there’s no manual calculations needed.

How Ecommerce Sales Tax Works

Sales tax is always charged as a percentage of the total sale. Each state sets its own percentage, as well as parameters around which goods are eligible for sales tax. Some states add sales tax to everything, while others add it to nothing. And others still apply sales tax to some items and not to others. The rules change depending on the state and sometimes local jurisdictions override state rules with their own.

Selling online makes sales tax a bit tricker because your location is less straightforward. Your business’s headquarters might be in one state, with warehouses in another. And your customer base could be all over the country—or the world.

When the government looks at an online merchant’s sales tax, it considers the business’s connection to each state, or “sales tax nexus.” We will discuss sales tax nexus in more detail below, but it includes any state where you have a physical presence and may include where your customers are located and other business activities that tie you to a specific state.

This wasn’t always the case though. A few years ago, online merchants were only required to pay ecommerce sales tax to states where they have a physical presence.

Physical presence: A store, office, warehouse or other business facility as defined by the state

But the 2018 South Dakota vs Wayfair Supreme Court ruling changed that. Now, businesses with sales exceeding more than 200 transactions or $100,000 in in-state sales must collect and remit sales taxes to that state, even if they don’t have a physical presence there. Since the ruling, 45 states and Washington D.C. have implemented their own ecommerce tax laws.

States also get to choose the following sales tax factors:

Physical presence: States can decide which business activities qualify as a “physical presence.”
Economic threshold: States can impose higher transaction rates or gross sales amounts. Some states use only the in-state revenue and don’t count transaction rates.
Additional taxes: Several states have local sales taxes, which are added on top of the state sales tax.
Sales tax sourcing: States can choose whether they’re an “origin-based” or “destination-based” sales taxing source. Origin-based means states impose ecommerce sales tax based on where the business originated, while destination-based uses where the product is shipped. Most states are destination-based.
Marketplace facilitator: Several states have passed marketplace facilitator laws requiring third-party marketplace sites like Etsy or Amazon to collect and remit sales tax with each sale.

When a customer comes to your online store and makes a purchase, your checkout will automatically calculate the necessary sales tax based on the customer’s shipping and billing information. This tax is an additional line item and added to the total cost of the transaction.

In this Shop Pay example, the total cost for the products is $75 while the taxes are calculated at $8.63.

When to Charge Ecommerce Sales Tax

You’re responsible for sales tax if you sell a taxable product or service in a state where you have a sales tax nexus. If you qualify, you’ll need to collect and remit the taxes back to the appropriate state.

What Is a Sales Tax Nexus?

If your online store conducts a certain amount of business in a particular state, it will trigger tax obligations, creating a sales tax nexus. You’ll always qualify for a sales tax nexus in your business’s home state. But you might also qualify in other states as well.

The following business activities may create a nexus:

Owning or renting a physical space: An office, warehouse, storage facility, store, or home office creates a presence in the state.
Staff: Having an employee, contractor, salesperson, or other personnel in a state may create a nexus.
Inventory: Storing inventory in a warehouse or through other third-party fulfillment centers like Fulfillment by Amazon could prompt tax responsibilities.
Click-through nexus: Some states have laws regarding third-party affiliates and sales tax obligations.
Temporary locations: Retail businesses that have a short-term physical business in a state, such as pop-up shops, trade shows, or craft fairs, can be required to collect sales tax.
Economic threshold: If your business exceeds a specific dollar amount in sales or a certain number of transactions to customers located within a state, you might need to collect and remit taxes to the state.

Food and groceries: Thirteen of the 45 states with a sales tax still tax groceries at a reduced or full rate.
Medications: Prescription drugs are almost always tax-exempt, but non-prescription and supplements are usually taxable items.

It’s also wise to periodically check with your state to ensure you tax your customers correctly.

How to Stay Compliant With Ecommerce Sales Tax

Register for Your Sales Tax Permit

Once you’ve determined that you have nexus with a particular state, you might need a sales tax permit for that state. Registering your business with the state’s taxing authority ensures compliance and will alleviate potential issues.

The specific steps to register for a permit vary by state, but generally, the process is as follows:

Gather essential business documentation, like your employer identification number (EIN).
Go to the state’s tax agency website.
Locate the “Sales and Use Tax” section—use “ecommerce” or “remote seller” as keywords for your search.
Follow the steps to register your business.

Set Up Your Business’s Tech Platforms

Keeping up with the laws and regulations of each state can be difficult. Choosing the right ecommerce platform and accounting software is important because many options automatically calculate ecommerce sales tax for you.

Prioritize platforms with settings to accurately and automatically calculate sales tax rates for each state where you have a nexus. Some programs, like TaxJar, integrate with many popular ecommerce platforms and can calculate the sales tax, track your economic nexus threshold in each state, and automatically submit returns for multi-state filings.

Consider Wholesale & B2B Sales Tax Exemptions

If you plan on selling products wholesale to other businesses, different sales tax rules may apply. Some states don’t require sales tax to be collected when you sell products to a business that will turn around and sell the product again. This is because, in the US, sales tax is only charged at the point of sale to the end customer.

Make sure any B2B customers you have that claim to be exempt from sales tax withholding have the proper exemption form from the state. You might consider not accepting exemption certificates just to play it safe; resellers that do unnecessarily pay sales tax can usually apply for a refund from the state.

Bottom Line

When you sell online, it’s important to keep up with current ecommerce sales tax rates and regulations in the states where your business, products, staff, and customers are located. Remote seller and marketplace facilitator laws will continue to evolve, so it’s important to integrate software and conduct occasional audits to ensure compliance.
