StateThreshold ($)Notes

The threshold you cross is the one you weren't watching.

Sellers look at Shopify, decide they're under in a state, and miss that Amazon pushed them over months ago. Exposure is cumulative across channels — this tool adds it up for you.

Fair questions.

Is it really free?

Yes — unlimited checks, no signup.

Is my sales data safe?

Your CSVs never leave your device. Everything is computed in your browser.

Can I trust the thresholds?

They're prefilled from commonly published 2026 figures, but tax rules change and measurement periods vary by state. Every threshold is editable — verify with your tax advisor before registering. This tool monitors; it doesn't give tax advice.

What counts toward the threshold?

Generally gross sales of taxable goods/services into the state, including marketplace sales in most states — which is exactly why multi-channel sellers get surprised. Marketplace facilitator rules may shift who remits, but the threshold math still matters.
