Who We Help: Sales Tax Help for eCommerce Businesses Selling Across State Lines
If you haven't done a formal review of where your business has sales tax obligations, there's a reasonable chance you're either registered in states where you don't need to be, unregistered in states where you do, or both
What actually creates nexus for eCommerce sellers
Nexus is the connection between your business and a state that requires you to collect and remit sales tax there. For eCommerce sellers, it comes from more places than most people realize.
Physical nexus comes from having a tangible presence in a state: employees, offices, or inventory stored there. If you use Fulfillment by Amazon, your inventory is sitting in fulfillment centers across the country, potentially in states you've never done business with directly. Each of those locations can create physical nexus.
Economic nexus comes from sales volume alone. Following the 2018 Wayfair ruling, every state with a sales tax has adopted economic nexus thresholds, typically $100,000 in sales or 200 transactions in a state within a calendar year. Cross that line and you have an obligation, regardless of whether you have a single employee or square foot of space there.
Marketplace sales add another layer of complexity. If you sell through Amazon, Etsy, or Walmart Marketplace, those platforms collect and remit tax on marketplace transactions in most states under marketplace facilitator laws. But those marketplace sales still count toward your economic nexus thresholds. Cross a threshold through marketplace volume alone and you may have obligations for your direct-channel sales that no platform is handling for you.
The platform doesn't solve the problem
A common point of false confidence for eCommerce businesses: "we have Shopify handling our tax." Sales tax software and platform plugins do useful things. They calculate rates, apply product taxability rules, and automate filing in states where you're already registered.
What they don't do is tell you where you need to be registered in the first place. That determination requires a human review of your actual footprint, your channels, your products, and your sales by state. Software calculates correctly inside the states you've configured. The configuration itself is a separate problem.
What working with TSTP looks like
We start with a nexus review: a systematic look at your physical presence, your sales volume by state, your marketplace channels, and your product mix. That review produces a clear picture of where you have obligations today, where you're approaching thresholds, and where you're in the clear.
From there, we handle registration in the states that require it, review your platform configuration to make sure it's set up to match your actual obligations, and provide ongoing support as your business grows and your footprint changes.
