Intermediate Quick Answer
Can I lose economic nexus if my sales drop below the threshold?
⚡ TL;DR
Yes — economic nexus can end when sales drop below the threshold for the full measurement period, but it doesn't self-terminate. You must monitor the measurement window, confirm you're below $100K in both the current and prior year for most states, and formally close the permit. Simply stopping collection and filing triggers delinquency.
Yes, economic nexus can end if sales fall below the threshold, but nexus doesn’t simply disappear when that happens. You must monitor the measurement period, confirm you’re below threshold, and formally close the permit through the state.
Key takeaways
- Economic nexus is not permanent, if you no longer meet the threshold in the measurement period, your nexus obligation can end
- Most states use current or prior calendar year: if you’re below $100K in sales in both the current and prior year, you generally no longer have economic nexus
- Some states use a trailing 12-month window, nexus ends more gradually as sales roll off the lookback period
- Nexus doesn’t self-terminate: you must formally close your sales tax permit with the state (file a final return, request permit cancellation); simply stopping collection and filing triggers delinquency
- Physical nexus created by FBA, employees, or warehouses does not go away because sales drop, those require separate resolution (pulling inventory, ending employment, closing facilities)
- Closing permits in 20+ states after a business contraction is operationally significant; consider whether the volume is likely to recover before going through the closure process
Frequently asked questions
Can I lose economic nexus and stop collecting sales tax if my sales drop?
Yes. If you no longer meet a state's economic nexus threshold in the measurement period (current or prior calendar year for most states), you may be eligible to close your permit and stop collecting. But this requires affirmatively closing the permit with the state, nexus doesn't simply disappear. You must continue filing through the permit closure date.
How do I know when it's safe to close a permit?
Check the state's measurement period. Most states use current or prior calendar year, you'd need to fall below the threshold in both years to be confident nexus won't apply in the next period. Some states use a trailing 12-month rolling window, which requires more continuous monitoring. Close the permit through the state's formal process; don't simply stop filing.
