What is Sales Tax Nexus and Why It’s Crucial for Your Business

Running a business is already challenging, and then there’s sales tax nexus—an issue that can turn things upside down if you’re not careful.

Understanding sales tax nexus is not just about compliance; it's about protecting your business from costly penalties, audits, and reputational damage.

But don't worry! We’re here to break down this often confusing topic into simple terms, so you can stay compliant and focus on what you do best: growing your business.

Understanding Sales Tax Nexus: What Does It Mean?

Let’s start with the basics. Sales tax nexus is just a fancy way of saying your business has a significant connection to a state that requires you to collect and remit sales tax there. This nexus definition for business is crucial to understand as it affects your tax obligations.

Sales tax nexus is an important concept for any business selling goods or services across state lines. It’s a key aspect of sales tax laws that determines whether or not you need to collect sales tax for that state.

 

What Does That Connection Mean?

This “connection” can come from a lot of different activities—like having a physical store, office, warehouse, or even just an employee working in the state. If you have a sales tax nexus, it means you need to be collecting and sending sales tax to that state.

For example, if you run a retail store in Colorado and open another location in Texas, you now have nexus in both states and must collect sales tax from customers in both places.

With each state having its own set of rules that can change frequently, it’s crucial for businesses to stay up-to-date and compliant. But don’t panic! We’ll walk you through what creates nexus and what you need to do about it.

 

What Creates Sales Tax Nexus for Businesses?

There are several ways your business can trigger state tax nexus, and it’s not just about having a store in a state anymore. Let’s break it down.

1. Physical Presence Nexus

If your business has a physical location, such as an office, store, or warehouse, in a state, you have physical presence nexus.

For example, if you store inventory in an Amazon warehouse in California, you’ve established physical nexus there. This means you’re responsible for collecting and remitting sales tax on sales made to California customers.

  • Have an office, store, or warehouse in a state? You’ve got nexus.

  • Employees working in a state? Nexus.

  • Storing inventory, say, with Amazon’s FBA service? You guessed it—nexus.

 

2. Economic Nexus

The rules for economic nexus changed significantly after the 2018 Supreme Court ruling in South Dakota v. Wayfair. Before this ruling, businesses only needed to collect sales tax if they had a physical presence in a state (1,2).

Now, states can require businesses to collect sales tax based on their economic activity alone. This means that even without a store or office, you might still need to register and remit sales tax if your sales in a state exceed a certain threshold.

What is Economic Nexus?

Economic nexus refers to a business presence in a state that’s significant enough to require you to collect and remit sales tax, even if you don’t have a physical presence there. This typically happens when your sales or transaction volume crosses a certain threshold.

 

Understanding Economic Nexus Thresholds

For most states, the threshold is $100,000 in taxable sales or 200 transactions over 12 months. However, states like California and Texas have higher thresholds of $500,000 in sales. It’s crucial to know the specific requirements for each state to stay compliant.

 

Real-World Example

Many small business owners are caught off guard by these rules and find themselves suddenly liable for collecting taxes in states they’ve never visited.

Let’s say you run an online business selling handmade furniture. Your business is based in Colorado, but you sell to customers all over the U.S. One day, you realize that your sales to customers in New York have reached over $500,000 this year.

Despite not having a physical store or employee in New York, you now have economic nexus there and are required to start collecting and remitting New York sales tax. In this scenario, your next steps would be to register for a sales tax permit in New York and ensure that you are collecting the appropriate sales tax from your customers in the state.

3. Marketplace Nexus

Selling on platforms like Amazon or Etsy? Some states make the marketplace collect tax for you, but don’t zone out yet—you might still have to handle some parts yourself, like reporting.

 

4. Digital Products and SaaS

Selling digital products or SaaS can make compliance even more complex. Different states have different rules for taxing digital goods. For instance, SaaS products are fully taxable in Connecticut but not in California. If you sell digital goods, be sure to check the specific rules for each state.

 

5. Affiliate Nexus

This occurs when a business has an affiliate relationship with another entity in the state. For example, if your New York business is affiliated with a company in Texas through shared ownership, you may have nexus in Texas.

 

6. Click-Through Nexus

This happens when you have agreements with individuals in a state to refer customers to your business, often through a website or other online means. This type of nexus is common for online businesses using affiliate marketing.

 

In short, if you’re doing business across state lines, there’s a good chance you have state tax nexus somewhere. Knowing where is the first step to staying compliant.

 

Why is Sales Tax Nexus Important for Business Owners?

If your business has nexus in a state, you are legally required to register for a sales tax permit, collect the appropriate sales tax from customers in that state, and remit it to the state’s tax authority. Failing to comply with sales tax laws can lead to penalties, fines, and even audits.

 

Avoiding Penalties and Fines

The cost of non-compliance can be steep. In California, for example, penalties can be as high as 25% of the tax owed, plus interest. This can quickly add up, especially for businesses with significant sales volume.

In Texas, failing to collect and remit sales tax can result in penalties up to 50% of the tax owed, while in New York, penalties can include both fines and criminal charges for repeated non-compliance.

 

Reducing Audit Risk

Non-compliance increases your risk of being audited. An audit can drain your time, money, and energy—things better spent on growing your business. By staying compliant, you reduce the likelihood of an audit and ensure that your business operations run smoothly.

 

Protecting Your Reputation

Your customers and partners trust you to do things right. Being slapped with non-compliance issues doesn’t look good, and it can erode that trust. Staying compliant with sales tax regulations demonstrates professionalism and integrity, helping to build and maintain a positive reputation in the marketplace.

How to Determine If Your Business Has Sales Tax Nexus

Wondering if your business has nexus? Don’t worry. Here’s how you can figure it out:

  1. Check Your Location: Look at where you have offices, warehouses, or even just employees. If you’ve got a physical footprint in a state, that’s nexus.

  2. Review Your Sales and Transactions: Check the states where you’re making sales. Have you crossed the $100,000 or 200 transactions threshold? If yes, you’ve got economic nexus.

  3. Inventory Locations: Are you storing goods in different states, like with Amazon FBA? This can create nexus, too.

  4. Marketplace Sales: If you’re using a marketplace, see what they’re collecting for you and what you might still need to handle. It varies by state, so check the rules!

By taking these steps, you can get a clearer picture of where you have nexus—and take action before the state knocks on your door.

 

Understanding Origin-Based vs. Destination-Based Sales Tax

It’s important to know whether the state uses an origin-based or destination-based sales tax rate:

Origin-Based

The sales tax rate is determined by the seller's location.

Destination-Based

The sales tax rate is determined by the buyer's location.

Understanding these rules helps ensure you collect and remit the right amount of sales tax, keeping your business compliant with varying state regulations.

 

How to Stay Compliant with Sales Tax Nexus Regulations

So, you’ve got nexus. What now? Here’s how to stay on top of it:

  • Keep Track of Nexus Triggers: Monitor where you’re selling and how much. Use a spreadsheet, or better yet, sales tax software that can track it for you.

  • Register for Sales Tax Permits: Once you’ve identified a state where you have nexus, register for a sales tax permit before you start collecting tax.

  • Collect the Right Amount of Tax: Use up-to-date rates for every state and jurisdiction where you have nexus. Sales tax rates can change, so make sure you’re on top of them.

  • File and Remit on Time: Don’t miss those filing deadlines! Late filings can result in penalties, and nobody needs that kind of stress.

Managing sales tax nexus can be challenging, but it’s essential for protecting your business from costly penalties and audits. By staying proactive and up to date with changing sales tax laws, you’ll not only avoid compliance issues but also maintain a strong reputation with your customers and partners.

 

Essential Steps for Economic Nexus Compliance

To comply with economic nexus, follow these three steps:

  1. Identify Where You Have Nexus: Review your sales and transaction history for each state to determine if you’ve exceeded the threshold.

  2. Verify Tax Rates and Jurisdiction Rules: Look up specific tax rates and rules for each state where you have nexus. Make sure you're applying the correct rates based on whether the state follows origin-based or destination-based tax rules.

  3. File and Remit Your Taxes: Register in each state where you have nexus, collect the right amount of sales tax, and file your returns on time to avoid penalties.

While these steps can be managed internally, professional services and automation tools significantly reduce the burden, allowing you to focus on your core business.

If managing these obligations feels overwhelming, consider partnering with experts who can provide guidance and support. Stay ahead of your compliance needs and focus on what matters most—growing your business.
