What is Economic Nexus?
Section titled “What is Economic Nexus?”Economic nexus is a sales tax concept established by the US Supreme Court’s 2018 South Dakota v. Wayfair decision. It means that a state can require an out-of-state seller to collect and remit sales tax based purely on the volume of sales made into that state — even if the seller has no physical presence there.
Before Wayfair, a seller generally only owed sales tax in states where they had a physical presence (office, warehouse, employees). Since 2018, virtually every state with a sales tax has enacted economic nexus rules that apply to remote and online sellers.
How the Calculator Works
Section titled “How the Calculator Works”Enter your trailing 12-month gross revenue and total number of transactions into the state, then select the state. The calculator applies the 2026 rules for that specific state and returns one of three assessments:
| Status | Meaning |
|---|---|
| Safe | Your sales are below the threshold. No registration obligation has been triggered. |
| Approaching Nexus | You are at 80% or more of the threshold. Monitor your sales closely. |
| Nexus Triggered | You have crossed the threshold. Registration, collection, and remittance are required. |
State-by-State Threshold Rules (2026)
Section titled “State-by-State Threshold Rules (2026)”Most states use a single revenue threshold. A small number of states have higher thresholds or dual-threshold logic.
Standard Threshold States — $100,000 Revenue
Section titled “Standard Threshold States — $100,000 Revenue”The majority of states trigger nexus at $100,000 in gross sales into the state during the trailing 12 months. Most of these states have eliminated their transaction-count alternatives — revenue is the only trigger.
States at this threshold include: Arizona, Arkansas, Colorado, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Puerto Rico, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, Wyoming, and Washington D.C.
Higher Revenue Threshold States
Section titled “Higher Revenue Threshold States”| State | Revenue Threshold | Transaction Threshold |
|---|---|---|
| California | $500,000 | None |
| Texas | $500,000 | None |
| New York | $500,000 | 100 (both required — see below) |
| Alabama | $250,000 | None |
| Mississippi | $250,000 | None |
Dual-Threshold States
Section titled “Dual-Threshold States”New York applies an AND rule: you must exceed both $500,000 in revenue and 100 transactions before nexus is triggered. A seller with $600,000 in sales but only 80 transactions has not triggered nexus.
Connecticut applies an OR rule: nexus is triggered when you exceed either $100,000 in revenue or 200 transactions — whichever occurs first. High-volume, low-value sellers may hit 200 transactions well before they reach $100,000.
No Statewide Sales Tax States
Section titled “No Statewide Sales Tax States”These four states have no statewide sales tax and no economic nexus obligations at the state level:
- Delaware
- Montana
- New Hampshire
- Oregon
Alaska — Local Nexus Only
Section titled “Alaska — Local Nexus Only”Alaska has no statewide sales tax, but the Alaska Remote Seller Sales Tax Commission (ARSSTC) administers a unified framework for local sales tax collection. Remote sellers exceeding $100,000 in sales into Alaska must register with the ARSSTC and collect tax for participating local jurisdictions. The transaction threshold was eliminated effective January 1, 2026.
What Counts Toward the Threshold?
Section titled “What Counts Toward the Threshold?”In most states, the economic nexus threshold is measured against gross sales — not taxable sales only. This typically includes:
- Direct sales through your own website or storefront
- Marketplace-facilitated sales (Amazon, Etsy, eBay, etc.) — even though the marketplace collects the tax on your behalf
- Sales of both taxable and exempt products in many states
Always verify the specific definition with your state’s revenue authority or a tax professional, as states vary on whether exempt sales count.
When Does Obligation Begin?
Section titled “When Does Obligation Begin?”Once you cross a threshold, most states require registration before your next taxable sale. Some states give a short grace period. Retroactive collection for sales made before crossing the threshold is generally not required.
Why This Matters for Online Sellers
Section titled “Why This Matters for Online Sellers”For e-commerce businesses selling across the US, economic nexus creates compliance obligations in potentially dozens of states. Common scenarios:
- Amazon FBA sellers may have inventory stored in Amazon warehouses across multiple states — creating physical nexus in those states, independent of the economic nexus thresholds shown here.
- SaaS and digital product sellers need to check both whether nexus is triggered and whether their product is taxable in that state (many states exempt SaaS; others tax it broadly).
- High-revenue sellers in California or Texas may focus on those states last due to the $500,000 threshold, even while complying with dozens of $100,000-threshold states.
