Which states have you crossed the economic nexus threshold in?
A private tracker for online and multi-channel sellers. Every state that levies a sales tax sets its own "economic nexus" threshold — a level of sales into that state past which the state can require you to register and collect its sales tax, no physical presence required. Enter your trailing-12-month sales into each state you sell into and get a per-state answer against that state's own published figure.
After using this, you can now see exactly which states you've crossed a registration threshold in and which you haven't, per state, against each one's own dollar and transaction-count rule — which used to mean cross-referencing fifty-one separate sets of figures by hand. See why the rule differs so much state to state, how this compares to an ongoing paid nexus-monitoring platform, or how this compares to tracking it in a spreadsheet yourself.
Selling on eBay, Etsy, Venmo, or a similar marketplace or payment app too? A crossed sales-tax threshold here is a separate question from whether a platform will send you a Form 1099-K — the 1099-K threshold checker answers that one.
Or import your orders (CSV)
Drop in an order export from Shopify, Etsy, Amazon or WooCommerce. The page finds the ship-to state, amount and date columns, keeps the last 12 months, totals each state, and estimates the date each uncrossed state would cross if your last 90 days of selling continued. The file is read in this browser and never uploaded.
| State | Sales, 12 mo | Orders | Of threshold | Status | Projected crossing |
|---|
Projection is a straight-line estimate from your last 90 days, not a forecast, and it uses a trailing 12-month window; several states measure the prior or current calendar year instead. Amounts use the order subtotal where the file has one, so tax you collected is not counted as a sale. Refunds, rows with an unreadable state or date, and repeated order ids are skipped and counted above.
Add a state
Each state is checked on its own — sales in one state are never added to another's total, because that is not how the threshold works. Use a trailing-12-month figure; a few states measure differently — see the FAQ below.

Common questions
What is economic nexus for sales tax?
Since the Supreme Court's 2018 South Dakota v. Wayfair decision, a state can require an out-of-state seller to collect and remit its sales tax once the seller's sales into that state cross a threshold the state sets for itself — no physical presence (office, warehouse, employee) required. Every state that levies a general sales tax has adopted its own version, each with its own dollar figure and, in some states, an added transaction-count test.
Do I add my sales from every state together to check the threshold?
No. Each state checks only the sales you made into that specific state, on its own. $80,000 into Idaho and $80,000 into Ohio does not combine into $160,000 for either state's own threshold — enter each state as its own row.
Do sales a marketplace already collected tax on still count toward my threshold?
In most states, yes — marketplace-facilitated sales (Amazon, Etsy, Walmart Marketplace collecting and remitting on your behalf) still count toward your own economic-nexus threshold in that state, even though the marketplace is the one currently remitting. Crossing the threshold can still create a registration or filing obligation for you once you sell outside that marketplace too. This tool counts every dollar you enter; it does not know which of your sales were marketplace-facilitated, so decide what to include based on your own state's marketplace-facilitator rule.
What happens if I cross a threshold and don't register?
States can generally assess back tax, penalties, and interest from the date nexus was established, not just from when you were caught — and in some states a responsible officer can be held personally liable for unremitted sales tax. This tool only estimates whether you've crossed a threshold; it does not calculate what you would owe or file anything on your behalf.
Why isn't this the same as a paid nexus-monitoring service like Avalara or TaxJar?
Those platforms connect directly to your sales channels, monitor your rolling totals continuously, calculate and file the actual returns, and charge an ongoing subscription for it. This tool is a free, one-time or periodic check you run by hand with numbers you already have — useful for a seller who wants to know where they stand today before an ongoing paid platform is worth the cost. See the full comparison.
Does every state use the same measurement period?
No. Most states look at the current or previous calendar year, but several (including Connecticut, Tennessee, Texas, and Vermont) use a trailing 12-month window instead, and a few states' own guidance differs in wording from state to state. This tool asks for a trailing-12-month figure as the safest common input, but does not model each state's exact measurement-period rule — confirm your specific state's counting window on its own department-of-revenue site.
