Frequently Asked Questions

What is economic nexus?
Economic nexus means you have a tax collection obligation in a state based solely on your sales activity there - even without a physical presence. After the 2018 Supreme Court ruling in South Dakota v. Wayfair, states can require remote sellers to collect and remit sales tax once they exceed certain revenue or transaction thresholds.
Is my sales data safe? Where does it go?
Your data never leaves your browser. All CSV parsing and analysis happens entirely on your device using JavaScript. We do not upload, store, or transmit your sales data to any server. The only data that touches our servers is your email address if you choose to unlock the full report.
Which states have sales tax?
45 states plus the District of Columbia have a state sales tax. The five states with no state sales tax are: Alaska (though local jurisdictions may tax through ARSSTC), Delaware, Montana, New Hampshire, and Oregon. These appear as "No Sales Tax" in gray on your results map.
What CSV format do I need?
Any CSV with at minimum a column for state and a column for revenue/amount. We automatically detect columns from common platforms like Shopify (shipping_province), Amazon (ship-state), WooCommerce (shipping_state), and more. You can also manually select columns using the dropdown menu after uploading.
How current is the threshold data?
Thresholds are updated as of January 2026. Most states use $100,000 revenue OR 200 transactions as their threshold, with exceptions for California, Texas, and New York ($500,000+). We recommend verifying current thresholds with your tax advisor before making compliance decisions.
What happens after I trigger nexus in a state?
Once you exceed a state's economic nexus threshold, you are legally required to register for a sales tax permit in that state, begin collecting sales tax from customers there, and file regular sales tax returns. Failure to do so can result in back taxes, interest, and penalties. Our Registration Service ($500/state) handles this entire process for you.
