Run Your Nexus Risk CheckTrack state thresholds in real time. Know exactly when nexus is triggered. Register with confidence.
Rolling 12 month tracking. State specific rules. Marketplace logic included.
Economic nexus monitoring software tracks your sales by state, applies threshold rules, and alerts you when revenue or transaction limits are exceeded.
The software continuously evaluates:
Manual spreadsheets cannot reliably handle multistate tracking once revenue scales.
To understand the legal framework behind threshold monitoring, review our Economic Nexus guide and the detailed Economic Nexus by State breakdown.
Run Your Nexus Risk CheckEconomic nexus is dynamic. Thresholds are not tested once per year. They must be evaluated monthly, especially in rolling 12 month states.
Without continuous monitoring, businesses risk:
Most companies discover nexus only after crossing multiple state thresholds. For a formalized compliance summary, review the Sales Tax Liability Estimate Report.
Sales are consolidated by destination state across all channels.
High volume sellers are evaluated against transaction based thresholds.
Rolling 12 month, prior calendar year, and current year rules are applied correctly.
Platform sales are included or excluded based on state specific rules.
Inventory and employee states are identified alongside revenue triggers.
For broader comparison see Physical vs Economic Nexus.
Rolling 12 month states evaluate the prior 12 consecutive months of sales at any given time.
Example: If total sales from May through April exceed 100,000 dollars, nexus is triggered in April even if the calendar year total is lower.
Manual tracking often fails because:
Use Rolling 12 Month Nexus Tracker for individual state testing. If you need a one time trigger calculation, try the Nexus Threshold Calculator.

If nexus was previously triggered, evaluate timing using When Do I Have to Register for Sales Tax. For a complete multistate overview, see the Sales Tax Exposure Dashboard.

Software automates:
For liability estimation use Sales Tax Liability Estimator. For risk scoring use Nexus Risk Score Tool.
Once nexus is confirmed:
If nexus existed in prior months, historical exposure may exist. Calculate back tax exposure using Back Sales Tax Calculator. Evaluate cleanup strategy using Nexus Registration Readiness Tool.
If you sell into more than five states, automated tracking is no longer optional. If nexus may have been triggered previously, estimate potential exposure with the Sales Tax Liability Estimator. For executive level reporting, access the State by State Nexus Report.
