A sales tax obligation triggered by reaching revenue thresholds in a state.

Why It Matters

Post-Wayfair (2018), states can require tax collection based on sales volume, not just physical presence. Growing D2C brands hit these thresholds quickly.

Practical Example

Scenario

A home goods brand analyzes their state-by-state sales.

Calculation

Florida: $105K (threshold: $100K) ✓ Must collect. New York: $480K (threshold: $500K) ✗ Not yet. Texas: $505K (threshold: $500K) ✓ Must collect

Result

Identified 8 states requiring registration, avoiding $40K+ in potential back taxes and penalties

Pro Tips

1Track sales by state monthly—crossing a threshold mid-year creates immediate obligation
2Know that thresholds are typically rolling 12 months or current/prior calendar year
3Some states have transaction count thresholds too (e.g., 200 transactions)

Common Mistakes to Avoid

Assuming you only have nexus in your home state—economic nexus changed everything in 2018

Not monitoring smaller states where thresholds are low ($100K is easy to hit)

Waiting until year-end to check—you should register when threshold is crossed

Frequently asked questions

Most states: $100K in sales or 200 transactions. Some are higher: California, Texas, New York at $500K. Some are lower or have no transaction test. Check each state you sell into.

States can audit and assess back taxes (often 3-4 years), plus penalties (typically 25%) and interest. Some offer voluntary disclosure programs with reduced penalties if you come forward.
