Understanding Ecommerce Nexus Rules for U.S. Sales Tax
If we’re being honest, sales tax isn’t exactly the reason most people start an ecommerce business. You’re here to create, innovate, and grow - not to navigate the labyrinth of nexus rules and tax filings.
But here’s the thing: if you want to grow and scale your brand, ignoring sales tax nexus is a fast track to penalties, audits, and a whole lot of unnecessary stress.
So, let’s break it down and get you on the right track. What is nexus in business, how does it impact your ecommerce sales tax strategy, and what do you need to do about it?
We’ll cover everything from economic nexus to affiliate nexus, all while showing you how to stay compliant and keep on growing.
What Is Nexus for Sales Tax?
At its core, nexus refers to the connection between your business and a state that obligates you to collect and remit sales tax. So, what does nexus mean for tax?
In simple terms, it means that if you have a nexus in a state, you are required to collect sales tax on orders from customers in that state and send it to the state's tax authority.
This could mean anything from having employees, warehouses, or inventory in a state (physical nexus), to reaching certain sales thresholds or transaction volumes (economic nexus).
With the rise of economic nexus laws, businesses are finding themselves obligated to collect sales tax in places they’ve never even visited.
Why Does Nexus Matter for Ecommerce Brands?
Understanding nexus is crucial for ecommerce brands because it defines where you must collect and remit sales tax, and failing to comply can lead to penalties, fines, or audits.
As your business grows, especially across state lines or internationally, nexus compliance ensures you avoid legal issues while keeping your customers happy with accurate tax rates.
Proactively managing nexus not only protects you from costly mistakes but also supports smooth business growth.
Understanding Economic Nexus: How Wayfair Changed Everything
Before 2018, states could only require sales tax collection from businesses with physical presence in the state, like a warehouse or employees.
But after the U.S. Supreme Court ruling in South Dakota v. Wayfair, the game changed. Now, economic nexus laws allow states to collect sales tax from businesses that exceed certain sales thresholds, even if they have no physical presence.
The threshold for economic nexus typically includes either $100,000 in sales or 200 transactions annually in a given state.
So, if you’re selling to customers in a state where you hit that threshold - bam! You have nexus, and that means it’s time to start collecting and remitting sales tax.
This ruling impacted nexus commerce for all online sellers, not just those with physical stores. Now, ecommerce businesses selling across multiple states need to track their nexus in each one to avoid penalties. Don’t worry, we’ve got a solution for that.
How to Determine If You Have Nexus in a State
The big question: how to determine if you have nexus in a state? It all depends on two key factors: sales volume and transactions.
But nexus laws vary by state, so you’ll need to check specific thresholds for each state where you’re doing business.
Here’s how it works:
1. Physical Nexus
If you have inventory, employees, or a physical location in a state, you automatically have physical nexus and must collect sales tax in that state.
2. Economic Nexus
As we mentioned earlier, if your sales or transactions in a state surpass the threshold (usually $100,000 in sales or 200 transactions), you’re obligated to collect sales tax in that state, even if you don’t have any physical presence.
3. Affiliate Nexus & Click-Through Nexus
If you have affiliates or third-party partners in a state (say, marketing partners or influencers), affiliate nexus might apply. Click-through nexus can also be triggered if you have an agreement with someone in that state who refers customers to your site.
These are just a few examples, but there are other specific rules to watch for, depending on where you’re selling. Keep in mind that every state has its own version of nexus tax laws, and they can change quickly.
Navigating State-Specific Nexus Rules
With nexus tax meaning varying by state, staying on top of which states you have nexus in can feel like juggling flaming swords while walking a tightrope. But staying compliant is key to avoiding penalties.
Each state has its own nexus laws, with different sales thresholds, rules for nexus (both physical and economic), and filing requirements. Missing one of these rules can lead to missed tax payments and hefty fines.
