Key takeaways
- Origin-based sales tax uses the seller’s location to determine the tax rate, while destination-based sales tax uses the buyer’s location, which is more common in the U.S.
- Most states use destination-based sourcing, especially following the Wayfair decision, which expanded remote seller obligations.
- Sales tax automation tools are essential for businesses selling across state lines, helping manage complex rate calculations and ensure compliance.
In short: Origin-based sales tax uses the seller’s location to set the sales tax rate. Destination-based sales tax uses the buyer’s location. Most U.S. states use destination-based sourcing, while a small group, including Texas and Arizona, use origin-based sourcing. The method affects how you calculate, collect and remit sales tax.
The world of sales tax is complex and brings many challenges for businesses. The rise of e-commerce and more complex state tax laws make it harder still. A key part of sales tax compliance is knowing the difference between origin-based and destination-based sales tax rates. This affects how you calculate, collect and remit sales tax, and it can hit your operations and bottom line.
In this guide, we explain the two main sales tax systems and how they apply across the states. We also cover what you need to know to stay compliant and efficient.
What is sales tax sourcing?
Sales tax sourcing is the method used to decide where sales tax should be collected and remitted. It matters because the sales tax rate can vary a lot depending on where the sale takes place. The United States uses two main methods: origin-based and destination-based sales tax sourcing. For a closer look, see March 2025 US Sales Tax Updates.
- Origin-based sales tax: In origin-based states, the seller’s location sets the sales tax rate. Wherever the buyer is, the rate is based on the seller's address.
- Destination-based sales tax: In destination-based states, the buyer’s location sets the sales tax rate. You calculate the rate based on where the product is delivered, not where you are located.
How does origin-based sales tax work?
Origin-based sales tax means you charge the sales tax rate of your physical location on every sale. This applies wherever your customers are within the state. Many see this as simpler for sellers, because you only need to account for one tax rate: your own.
For example, say your business is based in Texas, an origin-based sales tax state. You sell a product to a customer in another city in Texas. You would apply your own local sales tax rate to that sale. This keeps tax calculations simple, especially for small businesses or those with one location. You don’t need to track many tax rates across different regions.
However, origin-based sales tax can get more complicated if you sell across state lines or have several locations. In that case, you need to understand how origin-based rules work alongside destination-based rules in other states.
Which states use origin-based sales tax?
Only a small number of states currently use origin-based sales tax sourcing. These states are:
- Arizona
- California (Note: California is partially origin-based. State, county, and city taxes are origin-based, but district taxes are destination-based.)
- Illinois
- Mississippi
- Missouri
- New Mexico
- Ohio
- Pennsylvania
- Tennessee
- Texas
- Utah
- Virginia
How does destination-based sales tax work?
Destination-based sales tax means the buyer's location sets the sales tax rate. The rate is based on where the goods are delivered or where the service is performed. Many see this as fairer for consumers, because each customer pays the sales tax rate that applies where they live. Related reading: July 2024 US Sales Tax Rate Changes.
For instance, say your business is in Florida, a destination-based sales tax state. You sell a product to a customer in another part of the state, or even in another state. You would need to apply the sales tax rate for the buyer’s delivery address. This is more complex for sellers. You have to track and apply many sales tax rates, depending on where your customers are.
This complexity has led to advanced sales tax software that helps businesses manage the many rates they need to collect. If you run an e-commerce business or operate in several states, you need to understand destination-based sales tax. It helps you stay compliant and avoid penalties.

Which states use destination-based sales tax?
Most U.S. states use destination-based sales tax sourcing. These states are:
- Alabama
- Alaska (Only local sales taxes apply, as Alaska does not have a state-level sales tax)
- Arkansas
- Colorado
- Connecticut
- Delaware (No state sales tax)
- Florida
- Georgia
- Hawaii
- Idaho
- Indiana
- Iowa
- Kansas
- Kentucky
- Louisiana
- Maine
- Maryland
- Massachusetts
- Michigan
- Minnesota
- Nebraska
- Nevada
- New Jersey
- New York
- North Carolina
- North Dakota
- Oklahoma
- Rhode Island
- South Carolina
- South Dakota
- Vermont
- Washington
- West Virginia
- Wisconsin
- Wyoming
How does sales tax sourcing affect remote sellers?
Sales tax sourcing matters more for remote sellers since the 2018 U.S. Supreme Court decision in South Dakota v. Wayfair, Inc. This ruling let states require remote sellers to collect and remit sales tax. That includes online businesses with no physical presence in the state. This rule is known as economic nexus. It has led many states to adopt destination-based sales tax systems, so they capture tax revenue from out-of-state or remote sellers.
For remote sellers, applying the correct destination-based sales tax rate to each sale is critical. If you fail to comply, you can face large penalties and back taxes. The Wayfair decision has also led more businesses to use sales tax automation tools to manage these complex duties.
How can you manage sales tax compliance?
Many businesses manage sales tax compliance across several states with sales tax automation software. It helps them simplify their processes. Tools such as the one offered by LumaTax can work out the correct sales tax rate from the buyer's location. They apply the right taxes to each sale and help you pay them on time to the correct state and local authorities.
If you have a physical presence in several states or sell online, this kind of software can be crucial. It helps you stay compliant and cuts the admin work of managing sales tax.
What is the future of sales tax sourcing?
The trend toward destination-based sales tax sourcing is likely to continue. It is driven by the growth of e-commerce and the need for states to capture tax revenue from online sales. As more states move to destination-based systems, you will need strong sales tax processes. You will also need to keep up with changes in tax laws.
However, managing sales tax across different states and local areas is still a big challenge for businesses. Ongoing efforts to simplify and standardize sales tax laws may help in time. One example is the work of the Streamlined Sales Tax Governing Board, which aims to create more uniform rules across states.
Why does the difference between origin-based and destination-based sales tax matter?
The difference between origin-based and destination-based sales tax matters for any business that sells goods or services. This is especially true if you sell across state lines or online. Your sourcing method affects how you calculate and collect sales tax, how complex your tax duties are, and your overall compliance plan.
You must keep up with the sales tax laws in each state where you operate or sell, as these laws keep changing. Your state may follow an origin-based or a destination-based system. Either way, you need the right tools and knowledge to manage many sales tax rates in a changing landscape.
