It’s a crisp November morning in Asheville, and my client Emma is staring at a stack of tax notices that makes her want to throw her laptop across the room. She runs a small online shop selling handmade knit scarves—no physical store, no warehouse, just her spare bedroom and a Shopify site. Last year, she made $180,000 in sales across 32 states, and she assumed since she had no physical presence anywhere, she didn’t need to collect sales tax. Now she’s facing $12,000 in back taxes, penalties, and interest from five different states that claim she “triggered economic nexus.” She thought remote selling meant tax-free freedom, but instead, she’s stuck in a bureaucratic nightmare that’s eating into her profits. I’ve seen this exact panic with hundreds of remote sellers—they launch their businesses, make sales across state lines, and have no idea the 2018 Wayfair Supreme Court ruling changed everything. After 7 years of helping non-US and US-based remote sellers navigate state sales tax (and negotiating down countless back-tax bills), I’m breaking down exactly how to avoid paying sales tax in multiple states—with real stories, brutal compliance lessons, and actionable strategies that actually work. Because when you’re a remote seller with no physical presence, the difference between keeping your profits and getting drained by state taxes is knowing where (and when) you’re legally required to collect.

First, let’s get the foundational truth out of the way: The “physical presence rule” is dead. Before 2018, remote sellers only had to collect sales tax in states where they had a physical presence—like a warehouse, office, or employee. But then came South Dakota v. Wayfair, a Supreme Court case that flipped the script. The ruling said states could require remote sellers to collect sales tax even if they had no physical presence, as long as they met a certain “economic nexus” threshold. Now, every state with a sales tax has its own economic nexus rules—usually $100,000 in annual sales or 200 transactions within the state (or both) . That means if you sell $10,000 worth of products to customers in Maine, you’re fine, but if you hit $100,001, you’re legally obligated to register for a sales tax permit in Maine and start collecting tax . Emma’s mistake? She never tracked her sales by state—she just watched her total revenue grow, oblivious that she’d crossed thresholds in five states. That’s the first rule of remote seller tax compliance: You can’t avoid multi-state taxes if you don’t know where you’re triggering nexus.

Let’s start with the biggest myth I hear: “I’m a remote seller with no physical presence, so I don’t have to collect sales tax anywhere.” Total lie. I had a client in Vancouver (Canada) who sells eco-friendly phone cases to US customers—no US office, no US employees, just a Shopify store and a dropshipping supplier in California. He made $220,000 in sales to customers in New York last year, well above New York’s $100,000 economic nexus threshold. When New York’s tax department sent him a $15,000 bill, he argued he had no physical presence, but the state pointed to Wayfair and his sales volume. He ended up paying $8,000 (we negotiated down the penalties) and registering for a New York sales tax permit. The lesson? Physical presence doesn’t matter anymore—economic nexus is king. But here’s the good news: Economic nexus is state-specific, and if you stay below each state’s threshold, you’re off the hook. That’s how smart remote sellers avoid multi-state taxes—they track their sales by state religiously and adjust their strategies to stay under thresholds where possible.

Another critical strategy: Leverage marketplace facilitator laws. If you sell on Amazon, eBay, Shopify, or Etsy, chances are the platform is already collecting and remitting sales tax on your behalf. These platforms are considered “marketplace facilitators,” and most states require them to handle sales tax for third-party sellers. I had a client in Austin who sells vintage vinyl records on Amazon and his own independent website. He was stressing about collecting tax in 15 states where he had economic nexus, but then we realized Amazon was handling tax for all his Amazon sales—he only needed to worry about his independent website sales, which were below the threshold in every state. That cut his compliance burden by 80%. But don’t assume marketplace facilitation is a free pass—some states (looking at you, Alabama and Florida) have exceptions for certain products, and if you sell on multiple platforms, you still need to track which sales are covered. A client in Miami sold handmade jewelry on Etsy and Instagram Shops—Etsy collected tax, but Instagram didn’t (at the time), so she had to register in Florida when her Instagram sales crossed the $100,000 threshold. The key is to audit every sales channel and confirm who’s collecting tax—don’t just assume it’s being handled.

Let’s dive into a real-world example of how to avoid multi-state taxes by staying under thresholds. My client Jake runs a digital print shop from his home in Toronto, selling wall art to US customers. He wanted to expand his sales but didn’t want to deal with registering in dozens of states. We set up a system where he tracks sales by state using Shopify’s tax reporting tool—every month, he pulls a report showing how much he’s sold to each state. When his sales to California hit $95,000, he paused marketing to California customers for the rest of the year, redirecting his ads to states where he was far below the threshold (like Montana and New Hampshire, which don’t have sales tax at all). He also offered a “pre-order” option for California customers, pushing their purchases to the next calendar year so he wouldn’t cross the $100,000 threshold. That year, he made $230,000 in sales without triggering economic nexus in any state—no registrations, no tax filings, no headaches. The strategy worked because he was proactive: He didn’t wait until he got a tax notice to act—he monitored his sales and adjusted his approach to stay compliant.

Now, let’s talk about resale certificates—another tool that can save remote sellers from unnecessary tax burdens. If you’re dropshipping (meaning your supplier ships directly to customers), you can use a resale certificate to avoid paying sales tax to your supplier. Here’s how it works: When you buy products from a US supplier to resell to customers, you give them a resale certificate, which tells them the products are for resale and exempt from sales tax. Without the certificate, your supplier will charge you sales tax, which you can’t recover unless you’re registered in that state. I had a client in Berlin who dropshipped fitness equipment from a supplier in Illinois. She was paying 6.25% Illinois sales tax on every order, which added up to $3,000 a year. When we got her a valid Illinois resale certificate (yes, non-US sellers can get them!), her supplier stopped charging sales tax, saving her thousands. But resale certificates aren’t one-size-fits-all—each state has its own form, and some states (like Maine) require you to register for a sales tax permit before you can get one . A client in London tried to use a California resale certificate for a supplier in Texas, and it was rejected—she had to get a Texas-specific certificate. The lesson? Get the right resale certificate for each supplier’s state, and keep copies on file—tax auditors love to ask for them.

Another key point: Understand which products are taxable (and which aren’t). Not all products are subject to sales tax in every state—some states exempt clothing, food, or digital products. My client Lisa sells organic baby clothes from her home in Vancouver. She was worried about collecting tax in New York, but then we realized New York exempts clothing under $110 from sales tax. Since her clothes were all under $100, she didn’t have to collect tax on New York sales—even if she crossed the economic nexus threshold. That saved her from registering in New York and filing monthly tax returns. Similarly, a client in Seattle sells digital planners—most states don’t tax digital products, so she only has to collect tax in a handful of states (like Texas and Wisconsin) that do tax digital goods . The mistake many remote sellers make is assuming all their products are taxable—take the time to research each state’s tax rules for your product category. You might be surprised how many exemptions exist.

Let’s tackle the scariest scenario: You’ve already crossed a state’s economic nexus threshold and haven’t been collecting tax. What do you do? Panicking won’t help—but ignoring the problem will make it worse. I had a client in Melbourne who sells skincare products and realized she’d crossed the $100,000 threshold in California six months earlier. She was terrified of penalties, but we helped her apply for California’s Voluntary Disclosure Agreement (VDA) program. VDA programs let sellers come forward voluntarily, pay back taxes without penalties, and get into compliance. She ended up paying $4,500 in back taxes (no penalties) and registering for a California sales tax permit. The alternative? If California had found her first, she would have owed the back taxes plus 25% in penalties and interest—doubling her bill. Most states offer VDA programs, and they’re worth using if you’ve made a mistake. The key is to act fast—don’t wait for a tax notice to start the process.

Now, let’s talk about the biggest mistakes remote sellers make when it comes to multi-state sales tax. Mistake #1: Not tracking sales by state. This is Emma’s mistake—she just looked at total sales, not state-by-state breakdowns. Without this data, you’ll never know when you’ve triggered economic nexus. Mistake #2: Assuming all states have the same threshold. While $100,000 or 200 transactions is common, some states are different—Massachusetts is $100,000, but Rhode Island is $200,000. A client in Toronto sold $150,000 to Rhode Island customers and thought she was safe, but no—Rhode Island’s threshold is higher, so she was fine. But if she’d sold that amount to Massachusetts, she would have needed to register. Mistake #3: Forgetting about use tax. Use tax is a “hidden” tax that customers are supposed to pay if the seller doesn’t collect sales tax. But some states are cracking down on sellers who don’t collect tax, arguing that the seller is responsible for ensuring tax is paid. A client in Berlin sold $80,000 to customers in Colorado—below the economic nexus threshold—so she didn’t collect tax. But Colorado sent her a notice saying she should have informed customers about use tax, and she had to pay a $500 fine for not including a use tax disclosure on her website. Mistake #4: Ignoring non-sales-tax states. Montana, New Hampshire, Delaware, Oregon, and Alaska don’t have state sales tax—you’ll never have to collect tax there, no matter how much you sell. A client in Vancouver wasted hours researching tax rules for Montana, only to realize she was overcomplicating things.

Let’s walk through a step-by-step example of how to set up a tax compliance system for remote sellers. First, choose a tax tracking tool—Shopify, WooCommerce, and BigCommerce all have built-in tax reporting, but for more complex businesses, tools like TaxJar or Avalara can automate the process. My client Sarah runs a remote candle business from Montreal, and she uses TaxJar to track sales by state, monitor thresholds, and generate reports. Second, audit your sales channels—confirm which marketplaces (Amazon, Etsy) are collecting tax and which (independent websites, Instagram Shops) aren’t. Third, research each state’s rules: What’s the economic nexus threshold? Is your product taxable? Do you need a resale certificate for your suppliers? Fourth, set up alerts—most tax tools let you set up notifications when you’re approaching a state’s threshold, so you can adjust your strategy. Sarah set up alerts for when sales to any state hit $80,000, giving her time to pause marketing or offer pre-orders. Fifth, keep detailed records—save sales reports, resale certificates, and tax filings for at least 3-5 years. Tax auditors can go back that far, and you’ll need the documentation to prove compliance.

Now, let’s debunk some common myths about remote seller sales tax. Myth #1: “I’m a non-US seller, so I don’t have to collect US sales tax.” Wrong. The Wayfair ruling applies to all remote sellers, regardless of where they’re located. If you sell to US customers and cross a state’s economic nexus threshold, you have to collect tax—even if you’re based in another country. Myth #2: “If I don’t collect tax, the customer will pay use tax.” Technically, yes, but most customers don’t pay use tax, and states know that. They’ll go after the seller first because it’s easier to collect from a business than thousands of individual customers. Myth #3: “Registering for a sales tax permit is complicated and expensive.” It’s actually pretty straightforward—most states let you register online for free or a small fee (usually $10-$50). A client in Toronto registered for a California sales tax permit in 30 minutes, and the whole process cost $20. The paperwork is minimal, and the peace of mind is worth it. Myth #4: “I have to file tax returns in every state where I sell.” No—only in states where you have economic nexus (or physical presence). If you stay below the threshold in all states, you don’t have to file any state tax returns.

Let’s talk about when it’s worth registering in multiple states—because sometimes, avoiding multi-state tax isn’t the best strategy. If a state is a major source of revenue (say, 30% of your sales), registering and collecting tax might be better than limiting your sales there. My client Mike sells outdoor gear from his home in Vancouver, and California is his biggest market—accounting for 40% of his sales. Instead of limiting sales to California to stay under the threshold, he registered for a sales tax permit. Yes, he has to file monthly tax returns, but the revenue from California customers far outweighs the compliance costs. He also uses the registration to his advantage—he can now offer faster shipping by partnering with a California-based fulfillment center (without worrying about creating physical nexus, since he’s already registered). The key is to weigh the costs (time, paperwork) against the benefits (increased sales, customer satisfaction). For most sellers, it’s a no-brainer to register in their top 1-2 states and limit sales in others to avoid multi-state compliance.

Let’s wrap up with the universal rules I’ve learned the hard way—rules that will save you time, money, and stress. Rule #1: Track sales by state—always. Use a tax tool or spreadsheet to monitor how much you’re selling to each state, and update it monthly. Rule #2: Know your thresholds—research each state’s economic nexus rules and set up alerts to avoid crossing them accidentally. Rule #3: Leverage marketplace facilitators—let Amazon, Etsy, and other platforms handle tax collection whenever possible. Rule #4: Get resale certificates for dropshipping suppliers—this will save you from paying tax on inventory you’re reselling. Rule #5: Be proactive about compliance—don’t wait for a tax notice to address issues. If you cross a threshold, register for a permit. If you make a mistake, use a VDA program. Rule #6: Understand product exemptions—some products are tax-free in certain states, so don’t collect tax if you don’t have to.

The bottom line: Remote selling doesn’t mean you’re off the hook for state sales tax, but it also doesn’t mean you have to pay tax in every state. By tracking your sales, leveraging marketplace facilitators, using resale certificates, and staying under economic nexus thresholds, you can avoid multi-state tax burdens and keep more of your profits. The sellers who get into trouble are the ones who ignore tax rules, assume they’re exempt, or don’t track their sales. The sellers who thrive are the ones who are proactive, informed, and willing to put in a little work to stay compliant.

If you’re feeling overwhelmed, start small: Pull a state-by-state sales report for the last year. Identify which states you’re close to the threshold in, and set up a tracking system for the current year. Research whether your product is taxable in those states, and confirm if your sales channels are collecting tax. That’s it—you don’t have to solve all your tax problems today. Just take the first step toward compliance.

At the end of the day, state sales tax for remote sellers is about balance: You want to grow your business and reach customers across the US, but you don’t want to get bogged down in tax filings or hit with unexpected bills. By following the strategies in this article, you can have the best of both worlds—expanded sales without the multi-state tax headache. Trust me—I’ve helped hundreds of remote sellers do it, and you can too.
