There is no national sales tax threshold.

Each state defines:

Multistate sellers must evaluate nexus separately in every jurisdiction where sales occur. See Economic Nexus for foundational concepts.

What the State Nexus Lookup Tool Shows

For each state, the tool displays:

Revenue Threshold

The annual sales amount that creates economic nexus.

Transaction Threshold

Whether a 200 transaction rule or similar rule applies.

Measurement Period

Rolling 12 month, prior calendar year, or current year evaluation.

Marketplace Inclusion

Whether marketplace sales count toward threshold calculations.

Registration Notes

When registration is required after thresholds are exceeded.

For precise threshold testing use Threshold Testing Tool.

Rolling vs Calendar Year States

States use different measurement systems.

Rolling 12 Month States

Evaluate the prior 12 consecutive months at any time.

Prior Calendar Year States

Evaluate the previous January through December totals.

Current Calendar Year States

Evaluate sales during the ongoing year.

Failure to apply the correct measurement period can lead to late registration. For rolling tracking use Rolling 12 Month Nexus Tracker.

Marketplace Rule Variations by State

Marketplace facilitator laws differ significantly.

In some states:

In others:

Even where marketplaces collect tax, direct website sales must still be evaluated. Review Marketplace Nexus for deeper analysis. Track multichannel thresholds using Marketplace Nexus Tracker.

Physical Nexus Considerations

Economic thresholds are only one trigger.

Physical presence such as:

May create nexus before revenue thresholds are met. See Physical vs Economic Nexus for a full comparison. After reviewing state rules, test your data using Threshold Testing Tool.

After Looking Up a State

Once you confirm threshold rules, next steps include:

  1. Testing your sales data against the threshold.
  2. Identifying trigger month.
  3. Evaluating registration timing.

Use Nexus Threshold Calculator to determine exact trigger date. Review When Do I Have to Register for Sales Tax for timing guidance. If nexus was previously created, estimate exposure using Sales Tax Liability Estimator and Back Sales Tax Calculator. For a formalized compliance summary, review the Sales Tax Liability Estimate Report.

Who Should Use a State Nexus Lookup Tool

If you sell into multiple states, manual rule tracking becomes risky. For continuous tracking across all states, use Multistate Monitoring System. For executive level reporting, access the State by State Nexus Report.
