Unsure where you owe sales or use tax
Run Your Nexus Risk CheckAutomatically calculate trailing 12 month sales and know the exact month nexus is triggered.
Trailing calculations. State specific logic. Real time alerts.
A rolling 12 month nexus tracker calculates your trailing 12 month sales by state and determines when economic nexus thresholds are exceeded. Many states require continuous measurement instead of calendar year totals.
This tracker:
Manual spreadsheets often miss mid year triggers.
Many states use rolling evaluation. See Economic Nexus Thresholds by State for details.
Track My Rolling ThresholdsRolling 12 month nexus means a state evaluates the prior 12 consecutive months of sales at any given time.
Example: If sales from June through May exceed 100,000 dollars, nexus is triggered in May even if calendar year totals are lower.
This differs from prior calendar year states, which test only annual totals. See Economic Nexus by State for measurement differences.
Businesses frequently:
Because rolling measurement shifts every month, manual review is unreliable. A dedicated rolling 12 month tracker recalculates continuously.
Sales are consolidated by destination state across all channels.
Aggregate trailing 12 month totals.
Apply state revenue and transaction thresholds.
Identify first month threshold was exceeded.
Flag states approaching 75 percent and 90 percent of thresholds.
For one time threshold testing use Threshold Testing Tool.
Some rolling states also use transaction thresholds.

For physical presence triggers see Physical vs Economic Nexus. Confirm registration timing with When Do I Have to Register for Sales Tax.

If the trigger occurred in prior months, historical exposure may exist.
Annual testing may identify thresholds too late.
Rolling tracking:
Continuous monitoring is essential for multistate sellers. For consolidated tracking across all states, see Sales Tax Exposure Dashboard. For executive level reporting, access the State by State Nexus Report.
