Check the official pageMost 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: $100,000 sales or 200 transactions applies in 35+ states. Timeline: varies by state; some require registration within 30 days of exceeding.

Common Mistakes
❌ Assuming all states use the $100,000 / 200 transaction threshold
💥 Consequence: Missing states with different thresholds like CA ($500,000+) or PA
✅ 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
