About this tool
What the Sales Tax Nexus Calculator does
Since the 2018 Wayfair decision, US states can require remote sellers to collect sales tax once sales into the state pass an economic nexus threshold. Many states use $100,000 of sales, and some also count a number of transactions. Enter your sales by state and the thresholds to see where you may need to register.
Formula
- Nexus is met when sales ≥ the state sales threshold
- or, where a state counts them, transactions ≥ the transaction threshold
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Sales by state | 4 entries |
| Result | Value |
|---|---|
| States where a threshold is met | 2 |
| States checked | 4 |
How to read the result
Thresholds and measurement periods differ by state (previous or current calendar year, or rolling twelve months) and several states have dropped transaction counts. Check each state’s rules.
Physical presence, such as inventory in a fulfilment warehouse or remote employees, can create nexus regardless of sales.
Estimates only, not tax advice. Rates and thresholds change; confirm current figures with your tax authority or adviser.
