Sales tax nexus is the connection between a business and a state that requires the business to collect and remit sales tax. This connection can be created by having a physical presence, reaching certain sales thresholds, or selling through online marketplaces. Because sales tax rules vary by state, understanding when nexus applies is essential to staying compliant and avoiding penalties. In this guide, we’ll explain what sales tax nexus means, how it works, and how to manage it across the US.<\/p>\n\n\n\n

What Is Sales Tax Nexus?<\/strong><\/h2>\n\n\n\n

So what is sales tax nexus exactly? Sales tax nexus is the connection between your business and a state that requires you to charge sales tax to customers in that state. Once you have nexus, you’re legally obligated to register for a sales tax permit, collect sales tax from customers in that state, and remit those taxes to the state government.<\/p>\n\n\n\n

In practical terms, think of what is a sales tax nexus as the state’s way of saying, “Your business is active enough here that you need to follow our sales tax rules.” Before you establish nexus, you can usually sell to customers in a state without collecting sales tax. After nexus is triggered, tax filing and collection becomes mandatory.<\/p>\n\n\n\n

How Sales Tax Nexus Works Today<\/strong><\/h3>\n\n\n\n

Sales tax nexus didn’t always work this way. In the past, states could only require sales tax collection if a business had a physical presence, like an office, warehouse, storefront, or employees in the state. That changed in 2018, when the Supreme Court’s South Dakota v. Wayfair decision allowed states to enforce nexus rules based on economic activity, even if the seller has no physical footprint there.<\/p>\n\n\n\n

Today, many states create nexus when your sales or number of transactions cross certain sales tax nexus thresholds. This means remote sellers, ecommerce businesses, and online service providers can trigger nexus without ever setting foot in the state.<\/p>\n\n\n\n

Why Sales Tax Nexus Matters<\/strong><\/h3>\n\n\n\n

Understanding sales tax nexus is critical because the consequences of getting it wrong can be expensive. Failing to charge sales tax where required can lead to penalties, interest, and back taxes. You need to know where you have nexus to price products correctly and protect your gross profit vs net profit<\/a>. Each state has its own nexus rules, thresholds, and filing schedules. Noncompliance increases the risk of audits and unexpected tax bills.<\/p>\n\n\n\n

States are paying closer attention than ever to sales tax enforcement because this revenue funds public services and government programs. For business owners and remote sellers, knowing when nexus applies isn’t just good bookkeeping\u2014it’s essential tax planning and compliance.<\/p>\n\n\n\n

Types of sales tax nexus<\/strong><\/h2>\n\n\n\n

Several types of nexus can trigger sales tax obligations, with physical and economic nexus being the most common.<\/p>\n\n\n\n

Physical Nexus<\/strong> is the traditional standard, established when a business has a tangible presence in a state. This can include having an office, store, or warehouse, employing workers in the state (including remote employees), storing inventory in third-party fulfillment centers like Amazon FBA, owning or leasing property or equipment, or attending trade shows and sales events.<\/p>\n\n\n\n

Economic Nexus<\/strong> is the newer standard that applies even if you never set foot in a state. It’s triggered purely by how much you sell into that state. Most states now enforce economic nexus sales tax laws using thresholds based on total annual sales revenue (commonly $100,000), number of transactions (commonly 200), or a combination of both.<\/p>\n\n\n\n

For example, California sales tax nexus uses a $500,000 sales threshold for remote sellers, while New York requires both $500,000 in sales and 100 transactions. Florida sales tax nexus applies at $100,000 in remote sales with no transaction requirement. Once you cross a state’s threshold, you must register, collect, and remit sales tax just like a local business.<\/p>\n\n\n\n

Other Nexus Types<\/strong> include affiliate nexus (when in-state affiliates help drive your sales), click-through nexus (when you pay commissions to in-state partners for online referrals), and marketplace nexus (which affects sellers using platforms like Amazon, Etsy, or eBay where the marketplace facilitator may collect tax on your behalf).<\/p>\n\n\n\n

Physical vs. economic nexus<\/strong><\/h3>\n\n\n\n

Physical nexus is created when your business has a real, physical presence in a state. Common triggers include having an office or retail location, employing workers who live or work in the state, using independent contractors or sales reps, storing inventory anywhere in the state, owning or leasing property or equipment, or attending trade shows and in-person sales events. If your business has any of these connections, you almost certainly have physical nexus and must charge sales tax on taxable sales in that state.<\/p>\n\n\n\n

Economic nexus applies even without physical presence. Most states measure economic nexus thresholds on a calendar year basis, though some use rolling 12-month periods. You need to monitor your sales continuously to identify when you cross thresholds. Texas sales tax nexus, for instance, sets a higher threshold at $500,000 in annual sales, while Illinois sales tax nexus uses the more common $100,000 in sales or 200 transactions standard.<\/p>\n\n\n\n

Sales tax nexus by state<\/strong><\/h2>\n\n\n\n

Sales tax nexus thresholds and tax rates vary widely by state. While most states follow similar economic nexus standards, some have higher thresholds, unique requirements, or no statewide sales tax at all. This state tax matrix helps you understand where your obligations begin.<\/p>\n\n\n\n

States With No Statewide Sales Tax<\/strong><\/h3>\n\n\n\n

Five states impose no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon<\/strong>. Alaska has no statewide sales tax, though local jurisdictions may impose their own taxes. Delaware, Montana, New Hampshire, and Oregon have no sales tax at any level, eliminating sales tax nexus concerns for most sellers.<\/p>\n\n\n\n

States With Unique Thresholds<\/strong><\/h3>\n\n\n\n
