Unsure where you owe sales or use tax
Run Your Nexus Risk CheckSee where you have crossed state thresholds, when nexus was triggered, and what you must do next.
Built for multistate sellers tracking $100K+ revenue across jurisdictions.
Economic nexus by state refers to the specific revenue or transaction thresholds that trigger a sales tax registration requirement in each jurisdiction.
While most states use a $100,000 annual sales threshold, variations include:
Every state enforces its own nexus rules.
While this guide explains how economic nexus rules work across states, the complete revenue and transaction thresholds for every state are listed in the official Economic Nexus Thresholds by State table. Businesses reviewing nexus rules across multiple jurisdictions can use this table to quickly identify revenue thresholds, transaction thresholds, and measurement periods for each state.
Although the Wayfair decision enabled states to enforce economic nexus, each state implemented its own:
This means multistate sellers must evaluate nexus separately for every jurisdiction. There is no national standard. Because thresholds and measurement periods vary by jurisdiction, For a full breakdown of the revenue and transaction thresholds used by every state, see the complete Economic Nexus Thresholds by State table.
The majority of sales tax states use a $100,000 annual sales threshold.
However, differences exist in:
For real time state evaluation use State Nexus Lookup Tool. If you are new to multistate sales tax, start with our full Economic Nexus guide to understand how revenue thresholds create obligations. You can also review the Sales Tax Nexus overview to see how physical and economic triggers work together.
Some states historically used a 200 transaction threshold in addition to revenue. Many have eliminated transaction thresholds, but some still maintain them.
Transaction based nexus is especially relevant for:
Use Rolling 12 Month Nexus Tracker to monitor transaction volume accurately. If you are unsure whether you need to register now, see When Do I Have to Register for Sales Tax for state specific timing rules and practical examples.
States use one of three measurement systems:
Sales are evaluated continuously over the trailing 12 months.
Sales are measured from January 1 through December 31 of the previous year.
Sales are measured during the ongoing calendar year.
Failure to track rolling calculations often results in late registration. Instead of manually testing spreadsheets, you can automate multistate monitoring with our Economic Nexus Monitoring Software, which applies rolling 12 month calculations and state specific threshold rules in real time Sales Tax Nexus Hub.
Marketplace facilitator laws require platforms to collect tax in many states.
However:
Marketplace treatment varies by state. Track marketplace activity using Marketplace Nexus Tracker. Marketplace sellers should also review our Marketplace Nexus guide to understand how facilitator laws impact economic threshold calculations.
Certain states introduce additional complexity such as:
Multistate sellers must track rule changes continuously. Manual spreadsheets are insufficient once sales exceed $100,000 in multiple states. Remember that revenue is only one trigger. Inventory, remote employees, and warehouses may create physical nexus even before thresholds are exceeded. See Physical vs Economic Nexus for a side by side comparison.
Once nexus is created in a state:
If you believe nexus may have been triggered in prior periods, use the Sales Tax Liability Estimator and Back Sales Tax Calculator to evaluate potential exposure before registering. Review exposure risk using Nexus Risk Score Tool.
Effective multistate nexus monitoring requires:
