  • Use sales tax automation software (Avalara, TaxJar, and similar tools integrate with most platforms)
  • Review your marketplace reports monthly
  • Track your nexus thresholds state by state
  • Consult a tax professional when you expand into new markets
  • Sure, it’s a bit of work upfront. But the alternative — surprise tax bills, penalties, and interest — is far worse.

    The Bottom Line

    Marketplace facilitator laws have shifted a huge chunk of sales tax responsibility onto the platforms. For many sellers, that’s a welcome relief. But it’s not a free pass. Direct sales, nexus thresholds, registration rules, and record-keeping still demand your attention.

    The e-commerce tax world is messy, inconsistent, and — well, it’s evolving. Staying informed isn’t just smart; it’s essential. Because in this game, the sellers who understand the rules are the ones who sleep soundly at night.

    The e-commerce tax world is messy, inconsistent, and — well, it’s evolving. Staying informed isn’t just smart; it’s essential. Because in this game, the sellers who understand the rules are the ones who sleep soundly at night.

    Picture this: you’re selling handmade candles on Etsy, Amazon, and your own Shopify store. Sales are rolling in. Life is good. Then a letter arrives from a state tax department asking about unpaid sales tax — and you have no idea where it came from. Sound familiar? Honestly, this scenario plays out more often than most sellers realize.

    The culprit, usually, is confusion around marketplace facilitator laws. These rules have reshaped the sales tax landscape since the 2018 South Dakota v. Wayfair decision, and they’ve left plenty of e-commerce sellers scratching their heads. So let’s break down who owes what — and why it might not be you after all.

    What Is a Marketplace Facilitator, Anyway?

    A marketplace facilitator is basically the middleman — the platform that connects buyers and sellers. Think Amazon, eBay, Etsy, Walmart Marketplace, and even Airbnb. These platforms handle the listing, payment processing, and often the shipping logistics for third-party sellers.

    Here’s the deal: because these platforms are so deeply involved in the transaction, states decided it made more sense to hold them responsible for collecting and remitting sales tax, rather than chasing down thousands of individual sellers. It’s a bit like a landlord collecting rent from tenants and paying the property taxes — the landlord handles the paperwork, not each tenant.

    As of now, all 45 states that collect sales tax have some form of marketplace facilitator law on the books. That’s a big shift from just a few years ago.

    The Core Rule: Who Collects the Tax?

    When you sell through a marketplace facilitator, the platform is generally required to:

    • Calculate sales tax on each transaction
    • Collect that tax from the buyer
    • Remit it to the appropriate state or local tax authority

    And you, the seller? You’re off the hook for that particular sale — at least as far as collection goes. That’s the good news. The not-so-good news is that this doesn’t apply everywhere, and it doesn’t cover every situation.

    When You’re Still on the Hook

    Here’s where things get a little murky. Marketplace facilitator laws don’t erase all your tax obligations. There are several scenarios where you, the seller, remain responsible:

    1. Sales Through Your Own Website

    If you sell through your own Shopify, WooCommerce, or BigCommerce store, no facilitator is involved. You’re the one responsible for collecting and remitting sales tax — assuming you have nexus in the buyer’s state.

    2. Sales That Exceed Economic Nexus Thresholds

    Even if a marketplace handles most of your sales, your direct sales might push you over a state’s economic nexus threshold. Once that happens, you’re required to register and file in that state.

    3. Wholesale or B2B Transactions

    Marketplace facilitator laws typically apply to retail sales. If you’re selling wholesale or to businesses with resale certificates, those transactions may fall outside the facilitator’s scope.

    4. Services, Not Goods

    Some states tax certain services. If you’re selling a service through a marketplace, the facilitator rules might not cover it the same way they cover physical products.

    Economic Nexus: The Threshold That Trips Everyone Up

    Economic nexus is a fancy way of saying, “You’ve done enough business in our state; now you have to play by our tax rules.” Each state sets its own threshold — usually based on sales revenue, transaction count, or both.

    Here’s a quick snapshot of a few states:

    StateRevenue ThresholdTransaction Threshold
    California$500,000None
    Texas$500,000None
    New York$500,000100 transactions
    Illinois$100,000200 transactions

    Important nuance: In many states, marketplace sales don’t count toward your economic nexus threshold. So even if you sell $1 million on Amazon, you might not trigger nexus in a state where you have no other sales. But in some states? They do count. It varies. And yes, that’s frustrating.

    Registration and Filing: The Paperwork Doesn’t Disappear

    Even when the marketplace collects tax on your behalf, you may still need to register for a sales tax permit in certain states. Why? Because the state wants to know you exist — and they may want you to file a return showing zero tax collected (since the marketplace handled it).

    Some states require this. Others don’t. It’s a patchwork system, and honestly, it can feel like trying to assemble IKEA furniture without the instructions.

    Record-Keeping: Your Best Defense

    If there’s one thing that saves sellers during audits, it’s clean records. You’ll want to keep:

    • Marketplace sales reports (showing tax collected by the platform)
    • Direct sales records (showing tax you collected)
    • Exemption certificates from wholesale buyers
    • Nexus tracking data by state

    Trust me — when a state comes knocking, having these documents ready turns a potential nightmare into a simple conversation.

    Common Mistakes Sellers Make

    Let’s run through a few missteps that pop up again and again:

    1. Assuming the marketplace handles everything. It doesn’t. Your direct sales still need attention.
    2. Ignoring registration requirements. Some states want you registered even if you owe nothing.
    3. Mixing up nexus calculations. Marketplace sales may or may not count — check each state.
    4. Failing to update addresses. If your business address changes, your nexus picture can shift too.

    How to Stay Compliant Without Losing Your Mind

    Compliance doesn’t have to be a full-time job. A few practical steps can keep you on track:

    • Use sales tax automation software (Avalara, TaxJar, and similar tools integrate with most platforms)
    • Review your marketplace reports monthly
    • Track your nexus thresholds state by state
    • Consult a tax professional when you expand into new markets

    Sure, it’s a bit of work upfront. But the alternative — surprise tax bills, penalties, and interest — is far worse.

    The Bottom Line

    Marketplace facilitator laws have shifted a huge chunk of sales tax responsibility onto the platforms. For many sellers, that’s a welcome relief. But it’s not a free pass. Direct sales, nexus thresholds, registration rules, and record-keeping still demand your attention.

    The e-commerce tax world is messy, inconsistent, and — well, it’s evolving. Staying informed isn’t just smart; it’s essential. Because in this game, the sellers who understand the rules are the ones who sleep soundly at night.
