Important: Economic nexus thresholds typically apply to sales into each state, not your total nationwide revenue. This tool uses your total revenue as a proxy — if you sell to all states roughly equally, your per-state amounts would be lower. Consult a tax professional for state-specific nexus analysis.
How to Use This Sales Tax Nexus Checker
Enter your total sales revenue and number of transactions for each state where you have customers. The checker compares your numbers against each state's 2026 economic nexus thresholds and flags states where you've exceeded the threshold and must collect sales tax. It also highlights states where you're approaching the threshold so you can prepare for registration.
For physical nexus, review the checklist of common triggers (employees, inventory, property, trade shows) for each state. If you have any physical presence in a state, you have nexus regardless of your sales volume. The tool shows both economic and physical nexus indicators side by side.
All state thresholds are updated for 2026. Your data never leaves your browser. For official state-by-state resources, visit each state's Department of Revenue website or register through the Streamlined Sales Tax Registration System.
Frequently Asked Questions
What is sales tax nexus?
Sales tax nexus is the connection between a business and a state that creates an obligation to collect and remit sales tax. Nexus can be established through physical presence (offices, warehouses, employees, or inventory in a state) or economic activity (exceeding a state's sales or transaction thresholds). Once you have nexus in a state, you must register, collect sales tax from buyers in that state, and file returns — even if your business is physically located elsewhere.
What is economic nexus and the Wayfair decision?
Economic nexus was established by the U.S. Supreme Court in South Dakota v. Wayfair, Inc. (2018), which overturned the prior physical-presence requirement. States can now require remote sellers to collect sales tax if they exceed the state's economic thresholds — typically $100,000 in sales or 200 transactions in a calendar year. As of 2026, all 45 states with a sales tax (plus DC) have adopted economic nexus laws, though thresholds vary by state.
What are the economic nexus thresholds by state?
Most states use $100,000 in sales as their threshold. Some notable exceptions: California ($500,000), New York ($500,000), and Texas ($500,000). Several states have dropped the transaction-count threshold (200 transactions) and only use the dollar amount. A few states measure on a rolling 12-month basis rather than a calendar year. This checker includes the current threshold for each state.
Do I have physical nexus?
You have physical nexus in a state if you have: a brick-and-mortar location (office, store, warehouse), employees or sales reps working there, inventory stored there (including Amazon FBA inventory), property or equipment in the state, or trade show attendance exceeding a state's threshold (usually 15+ days). Some states also consider affiliate nexus — where an in-state entity refers customers to your website in exchange for commission.
What if I sell on Amazon, Etsy, or other marketplaces?
All 45 sales-tax states plus DC have marketplace facilitator laws that require the marketplace (Amazon, Etsy, Walmart, eBay, etc.) to collect and remit sales tax on your behalf for sales made through their platform. This generally relieves you of the collection obligation for marketplace sales. However, you're still responsible for sales made through your own website or other non-marketplace channels, and you may still need to register in states where you have nexus for reporting purposes.
How do I register to collect sales tax?
Register through each state's Department of Revenue (or equivalent agency) website. Many states participate in the Streamlined Sales Tax Registration System (SSTRS), which lets you register in multiple states through a single application at sstregister.org. After registration, you'll receive a sales tax permit and filing schedule (monthly, quarterly, or annually, depending on your volume). Never collect sales tax without a valid permit — it's illegal in most states.
What happens if I don't collect sales tax where I have nexus?
Non-compliance penalties vary by state but typically include back taxes (states can audit 3–4 years back), interest (usually 0.5%–1.5% per month), penalties (5%–25% of unpaid tax), and in extreme cases, criminal liability. Many states participate in amnesty or voluntary disclosure programs that waive penalties (and sometimes interest) for businesses that come forward voluntarily. It's almost always better to register proactively than to wait for an audit notice.
Which states have no sales tax?
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local jurisdictions to impose their own sales taxes, so some areas within Alaska do charge sales tax. If you only sell to customers in these five states, you have no state sales tax collection obligation — but you may still owe other taxes like business privilege tax (Delaware) or gross receipts tax (Oregon's CAT).
