Most US states use $100,000 in sales OR 200 transactions as the economic nexus threshold. However, some states differ: California, New York, Pennsylvania, Texas, and Illinois use $500,000+ thresholds. Some states count only sales, not transactions. Check each state individually — thresholds change annually. The standard: $100K sales or 200 transactions applies in 35+ states. Timeline: varies by state; some require registration within 30 days of exceeding.

⚠️WARNING

Nexus thresholds vary significantly by state — using a one-size-fits-all threshold can lead to non-compliance or over-registration

Penalties of 25-50% of unpaid tax, plus interest, for states where nexus exists but you haven't registered

🛡️ Prevention Steps

  • Review each state's specific threshold annually
  • Track both sales volume AND transaction count separately
  • Monitor state legislative changes

Common Mistakes

Assuming all states use the $100,000 / 200 transaction threshold

💥 Consequence: Missing states with different thresholds like CA ($500,000+) or PA (100 transactions only)

Fix: Check each state individually via state revenue department websites

Counting only the current year's sales when most states require 12-month trailing data

💥 Consequence: Missing nexus obligations or over-reporting

Fix: Use trailing 12-month data for each evaluation point

Ignoring marketplace facilitator laws — platforms like Amazon already collect on your behalf in many states

💥 Consequence: Double-collecting tax or unnecessary registration

Fix: Verify which states have marketplace facilitator laws before registering
