Unsure where you owe sales or use tax
Run Your Nexus Risk CheckTrack revenue, transactions, and state thresholds before nexus turns into liability.
Continuous monitoring across all sales tax states. Rolling calculations included.
Economic nexus tracking is the process of continuously monitoring your sales by state to determine when revenue or transaction thresholds are exceeded.
Proper tracking requires:
Most businesses discover nexus too late because they rely on annual spreadsheets.
Nexus is not a one time calculation. It changes every month as sales fluctuate.
Without continuous tracking, businesses risk:
The larger the multistate footprint, the higher the monitoring complexity. 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.
Effective economic nexus tracking includes five core components:
Gross and taxable sales must be aggregated by state.
High volume sellers may trigger nexus even below revenue thresholds.
Rolling 12 month, prior calendar year, or current year calculations must be applied correctly.
Platform sales may or may not count toward thresholds depending on state.
States periodically modify rules and remove transaction standards.
Use State Nexus Lookup Tool to verify state specific rules. Because thresholds and measurement periods vary by jurisdiction, we recommend reviewing our Economic Nexus by State breakdown along with the full Economic Nexus Thresholds by State guide for detailed comparisons.
Rolling 12 month tracking evaluates the prior 12 consecutive months of sales activity. Unlike calendar year tracking, this method updates monthly.
Example:
If you exceed $100,000 in March based on April to March sales, nexus is triggered immediately.
Manual tracking often fails because:
Automate this using Rolling 12 Month Nexus Tracker. 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.
These errors lead to delayed registration. Use Nexus Threshold Calculator to determine exact trigger dates.
You should implement automated nexus tracking if:
Manual methods break down quickly as revenue scales. Economic Nexus Monitoring Software provides real time state alerts. 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.
Tracking determines when registration is required. Compliance software calculates tax after registration. Many businesses implement compliance software too late because they never tracked thresholds.
Correct order:
Review risk exposure with Nexus Risk Score Tool. 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.
Businesses selling through:
Must consolidate all channels before testing thresholds. Marketplace sellers should also review our Marketplace Nexus guide to understand how facilitator laws impact economic threshold calculations. Marketplace inclusion rules differ by state. Track platform thresholds with Marketplace Nexus Tracker.
Tracking determines when registration is required. Compliance software calculates tax after registration. Many businesses implement compliance software too late because they never tracked thresholds.
Correct order:
Continuous monitoring reduces audit risk and prevents retroactive exposure. 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.
Track every state. Get alerts early. Register with confidence.
