What This Calculator Does
This sales tax nexus calculator helps ecommerce sellers, SaaS companies, and remote businesses determine which states require sales tax registration based on 2026 economic nexus thresholds established after the Supreme Court's 2018 South Dakota v. Wayfair decision. The calculator checks your revenue and transaction volume against each state's specific thresholds and identifies where you have a collection obligation. It also estimates potential sales tax liability for states where nexus exists.
The Formula
After the Wayfair decision, states can require remote sellers to collect sales tax if they exceed economic nexus thresholds, even without physical presence. Most states set thresholds at $100,000 in revenue OR 200 transactions per year (whichever is met first). Some states have higher thresholds: California, New York, and Texas use $500,000. Alabama and Mississippi use $250,000. Five states have no sales tax (Alaska, Delaware, Montana, New Hampshire, Oregon). The "OR" condition means exceeding either threshold triggers nexus.
Step-by-Step Example
Enter revenue data
Total annual revenue: $150,000. Total transactions: 500. Revenue distributed evenly across states.
Select distribution model
Even distribution selected: approximately $3,409/state and 11 transactions/state.
Review nexus results
At even distribution: 0 states with nexus (below $100,000/state threshold).
Try concentrated model
Top 5 states concentration: $30,000/state, 100 transactions/state. Still below most thresholds but approaching some. At $500K+ revenue concentrated in 5 states, nexus would trigger.
Real-World Use Cases
Ecommerce Compliance
Online sellers shipping physical products across state lines can identify which states require sales tax registration based on their sales volume by state.
SaaS Tax Planning
Software companies selling to customers in multiple states can determine nexus obligations. Many states now tax SaaS as tangible personal property or a taxable service.
Marketplace Seller Assessment
While most marketplace facilitators (Amazon, Etsy) collect sales tax on behalf of sellers, direct sales through your own website still create nexus obligations independently.
Common Mistakes to Avoid
Assuming marketplace sales do not count toward nexus thresholds. Some states include marketplace-facilitated sales in your economic nexus calculation, even though the marketplace collects the tax.
Waiting until you exceed thresholds to register. Most states require prospective registration, meaning you should register before or as soon as you exceed the threshold, not retroactively.
Ignoring states where you have physical presence. Economic nexus is in addition to physical nexus. Having an employee, office, warehouse, or inventory in a state creates nexus regardless of revenue.
Not accounting for exemptions. Some products and services are exempt from sales tax in certain states (clothing in Pennsylvania, groceries in many states, SaaS in some states). Nexus does not mean every sale is taxable.
Forgetting that thresholds reset annually. Most states measure economic nexus on a calendar year or trailing 12-month basis. Exceeding the threshold in one year creates an obligation for the following year.
