US Sales Tax Nexus Lookup & Calculator
Since the 2018 Wayfair decision, selling into a state can mean owing its sales tax even if you have never set foot there. Most states set economic nexus at $100,000 in sales or 200 transactions a year — cross that line and you must register, collect, file, and remit, in every such state. For a growing online seller, "where do I owe tax" quietly becomes a 20-state compliance project.
This tool checks your sales footprint against current state thresholds: enter annual sales and transaction counts per state and see exactly where you have triggered nexus, where you are approaching it, and what each state's filing frequency and rate look like. It distinguishes the two classic triggers — physical presence (office, warehouse, employee, inventory in an FBA warehouse) which creates nexus immediately, and economic activity which trips at the threshold.
The expensive mistake is ignoring it: states charge penalties and interest on uncollected tax, and marketplace facilitator laws (where Amazon/Etsy collect for you) do NOT cover your own Shopify or website sales. Many sellers discover nexus during due diligence for a business sale — the worst possible time, with years of back liability. Check thresholds quarterly as you grow; registering late voluntarily is vastly cheaper than being found.

Sales Tax Nexus Questions
What is economic nexus?
The rule (from South Dakota v. Wayfair, 2018) that selling enough into a state — typically $100,000 or 200 transactions/year — obligates you to collect its sales tax with no physical presence required.
Does Amazon collect sales tax for me?
Marketplace facilitator laws make Amazon/Etsy collect on marketplace sales — but NOT on your own website, Shopify store, or other channels. Those are still your responsibility.
What if I ignore nexus?
Penalties and interest on uncollected tax, backdated to when nexus began. Voluntary registration with disclosure programs is far cheaper than getting caught.
Do digital products count?
Depends on the state — some tax SaaS and digital goods, some do not, and thresholds may count them differently. Check per-state rules.
Is this legal advice?
No. Thresholds and rules change; this is a screening tool. A sales-tax specialist (or automated filer like TaxJar/Avalara) is the right next step once you trigger states.
