The thresholds used are sourced from each state's department of revenue and cross-referenced with industry references including the Streamlined Sales Tax Project. The data is updated when states change their laws. That said, tax rules can change — always verify with your state's DOR or a qualified tax professional before making compliance decisions.
If you've crossed an economic nexus threshold, you generally need to register for a sales tax permit in that state and begin collecting and remitting sales tax. Most states give you 30–60 days from crossing the threshold before you're required to collect. Contact the state's Department of Revenue or a sales tax professional immediately to avoid penalties.
No. This tool provides informational estimates based on published thresholds — it is not tax or legal advice and does not create a professional relationship. For decisions about sales tax registration, filing, or compliance, consult a qualified CPA or sales tax attorney.
Economic nexus is a legal obligation to collect and remit sales tax in a state based solely on your sales volume there — even if you have no physical presence in the state. Following the 2018 South Dakota v. Wayfair Supreme Court decision, all states with sales tax now enforce economic nexus. Thresholds are typically $100,000 in annual revenue or 200 transactions, though some states like California, Texas, and New York use higher thresholds.
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon — often called the NOMAD states. If you only sell into these states, you have no sales tax collection obligation at the state level (though Alaska allows local jurisdictions to impose local sales taxes).
