What is economic nexus?
Since the 2018 South Dakota v. Wayfair Supreme Court decision, states can require out-of-state sellers to collect and remit sales tax once their sales into that state cross an economic nexus threshold — typically a dollar amount of revenue, a number of transactions, or both. Thresholds and the way they combine vary by state, and several states have changed or removed their transaction-count rules in recent years.
Nexus Snapshot gives online sellers a fast, plain-English starting point for understanding where they may have crossed those thresholds — so you know where to look closer with a tax professional.
Frequently asked questions
What is economic nexus?
Economic nexus is a sales-tax obligation triggered when your sales into a state exceed that state's revenue or transaction threshold, even without a physical presence. It stems from the 2018 South Dakota v. Wayfair decision.
How does Nexus Snapshot estimate my obligations?
You enter your sales figures — either total US revenue and transactions for a quick upper-bound check, or exact per-state figures for an accurate read. We compare them against each state's published economic nexus thresholds and show where you may have crossed or are approaching a threshold.
Is this legal or tax advice?
No. Nexus Snapshot is an informational tool only and does not provide legal, tax, or accounting advice. You are responsible for your own compliance. Consult a qualified professional before acting on any result.
What is in the paid PDF report?
The $29 PDF includes your inputs, every state's thresholds and your status against each, the states you have triggered, measurement-period notes, a plain-English explanation, a timestamp, and the threshold data version used.
How current is the threshold data?
Thresholds are reviewed and updated quarterly. Each report shows the data version it was generated from. States change rules periodically, so always verify against the relevant state's department of revenue.
How many states have economic nexus thresholds?
47 of 51 US jurisdictions (50 states plus Washington DC) have an economic nexus threshold for remote sellers. Four — Delaware, Montana, New Hampshire, and Oregon — impose no general statewide sales tax and therefore have no threshold.
What is the most common economic nexus threshold?
$100,000 in annual sales is the most common threshold, used by 42 of the 51 US jurisdictions. California and Texas require $500,000, while New York requires both $500,000 in sales and 100 transactions. 18 jurisdictions also count the number of transactions (usually 200 orders), and the trend is toward dropping that test — Utah removed it in July 2025, Illinois in January 2026, and Kentucky follows in August 2026.
Do I need to register in every state where I have nexus?
Yes — crossing a state's economic nexus threshold generally triggers a registration obligation. You must apply for a sales-tax permit in that state, begin collecting tax on sales to customers there, and file returns on the schedule the state assigns. When your obligation starts and how far back it reaches varies by state, so consult a tax professional once you know where you've crossed.
What is the Wayfair decision?
South Dakota v. Wayfair, Inc. is a 2018 US Supreme Court decision that overturned the previous requirement for a physical presence to owe sales tax in a state. After Wayfair, states can require remote (online) sellers to collect sales tax based purely on economic activity — revenue or transaction count. All 47 jurisdictions that levy a statewide sales tax have since enacted economic nexus laws.
