Online sales taxes are a growing concern for businesses. Learn how to stay on top of changing regulations and to minimize the burden for your business.

Online sales tax plays an interesting and complex role in the tax world. To determine which sales are taxable to your customer and collectible by your business, you must understand what the point of origin is. Think of sales taxes as being a reasonable charge for reimbursing the government for a variety of costs it incurs during the sales process. Costs include contracts, sales tax law enforcement, and certain public goods.

What Is Online Sales Tax?

Online sales tax is a form of taxation for goods and services purchased on the internet. When businesses operate in a state that requires them to collect sales tax, they must do so whether the sales are made in physical (brick-and-mortar) or digital (online) locations. Collecting sales tax for online businesses can also be required if the goods are sold to individuals who live in a state with sales tax requirements, even if the business doesn't have a physical presence there. Internet sales tax regulations were introduced in an effort to bring all businesses selling products electronically onto an equal footing with the traditional, physical stores that were already required to pay sales tax.

Do You Need To Collect Sales Tax for Selling Online?

Whether you are selling goods or services online, it's important to consider tax obligations for online sales. Depending on the state or territory where your business is based, you may be liable to collect and remit local or state sales taxes from customers whenever you make a sale. If a customer is located in the same state as your business, then the tax for online sales must be collected and sent to the local agency per local regulations. Additionally, even if you do not have a physical presence in another state, you still may need to collect sales taxes from customers who live there because all states possess different laws concerning when sales tax needs to be collected and paid. To ensure compliance with all relevant authorities, businesses should familiarize themselves with their potential tax obligations before they engage in online sales transactions.

How Much Is Online Sales Tax?

For online businesses, sales tax works differently than it does for brick-and-mortar stores. Generally, the business is expected to collect sales tax online for any state where it has nexus, which can include a physical presence or ties to an affiliate. The rate of tax varies from state to state, though typical sales tax rates range between 5-7% in many states.

Some states may also require other taxes on online purchases, such as use taxes or gross receipts taxes. When operating online, businesses are expected to know which laws apply to customers in any state, and they must follow changing tax regulations at the state and local level to stay compliant with taxation laws.

How Does Online Sales Tax Work?

A Supreme Court ruling in 2018 fundamentally changed the way that online sales tax works. Prior to this 2018 ruling, online businesses only needed to collect sales tax for sales that occurred in states where they had a physical presence. The Supreme Court recognized that this gave out-of-state retailers an unfair advantage and ruled that states could now collect sales tax from businesses that had a significant connection or "nexus" to the state. Typically, a business is considered to have a nexus (and is therefore required to collect online sales tax) when:

  • It has a physical location in the state.
  • It has employees, affiliates, or independent contractors that live in the state.
  • Its sales to residents of the state exceed a certain threshold.

If a nexus is present, the business is responsible for complying with all applicable state and local taxes. This includes making sure to collect the proper amount of tax from the customer at the point of sale, then recording and submitting that tax to the appropriate government authorities.

Online Sales Tax Laws, Rules, and Regulations

The Supreme Court ruling in South Dakota vs. Wayfair, Inc. changed the legal landscape around the laws and regulations that affect sales tax requirements for online retailers. Over the past decade, states have increasingly passed laws that require businesses to collect sales taxes, even if they do not have a physical presence in the state. For companies that choose to operate fully or partially online, the onus falls on the business owner(s) to stay up to date on the current tax laws and how any state or local regulations impact the online business sales tax rules that may apply to the business.

For the business owner, many of these rules center around understanding some key terms:

Point of Origin-Based Tax Laws

In non-technical terms, point of origin means you are responsible for collecting and submitting sales taxes in the state where you physically operate your business. For instance, if you make a sale in Illinois, you need to collect and remit sales taxes on items sold in Illinois. While this tax structure was popular in many states prior to 2012, most states have moved to a tax model that allows them to more fairly benefit from businesses that earn a significant amount of sales revenue from the state.

Destination-Based Tax Laws

Many states, including Washington and Texas, choose to use a destination-based sales tax structure. This requires businesses to collect sales taxes based on the delivery location of their customer, or the destination of the product. Certain wholesale sales are not affected, however. These include vehicle sales, aircraft, boats, mobile homes, services, florists, and towing companies.

The Marketplace Fairness Act of 2013

In today's technology age, many consumers enter brick-and-mortar stores to physically research products. Then, they use their mobile devices to purchase the item online. Usually, companies offer online specials as a sales tool.

A bill titled Marketplace Fairness Act of 2013 attempted to level the playing field between traditional retail stores and online merchants. The bill sought to minimize the burden of collecting and remitting taxes to over 9,000 localities — including local, county, and state taxing authorities. Instead of considering all these localities, the bill imposes taxes only at the merchant-based point of origin. A key argument against the bill is the fact it lacks complete guidance on collecting and submitting appropriate taxes. This legislation has not yet been passed into law and is still ongoing.

Which States Require Sales Tax for Online Purchases?

In the U.S., states have widely different requirements for collecting online sales tax, depending on the type of product or service. While nearly all states have some kind of online sales tax requirements (only 4 states — Delaware, Montana, New Hampshire, and Oregon — do not have any laws governing the collection of sales tax), different states have different definitions of what creates a "nexus" and when a business meets the threshold for when sales tax is required to be collected.

Here is a detailed overview of the sales tax requirements for each state if your company does not have a physical presence within the state, effective as of October 9, 2023.
