Nexus Thresholds by State

Each state sets its own economic nexus thresholds, creating a complex compliance landscape. Most states use a combination of revenue and transaction thresholds, but the specific amounts vary significantly. This guide provides an overview of common threshold structures, but always verify current rules with each state department of revenue.

The variation in thresholds reflects different state policies. Some states want to capture more remote sellers and set lower thresholds. Others worry about burdening small businesses and set higher thresholds. The result is a patchwork of rules that requires careful tracking for businesses selling nationally.

Understanding thresholds is critical because exceeding them triggers registration and collection obligations. But thresholds also provide valuable information about where you're close to having nexus. Tracking your sales against thresholds helps you stay ahead of compliance requirements rather than scrambling after the fact.

Note that this information changes frequently. States revise thresholds, sometimes annually, to address inflation or changing economic conditions. Always verify current thresholds before making compliance decisions.

While states vary in their specific thresholds, common patterns emerge that help you understand the landscape.

The South Dakota model became the most common approach. Under this model, states use both a revenue threshold ($100,000) AND a transaction threshold (200 transactions). Either threshold alone can trigger nexus—you have nexus if you exceed $100,000 in sales OR if you have more than 200 transactions, regardless of the revenue amount.

Revenue-only thresholds simplify tracking but capture fewer sellers. Some states use only a revenue threshold—if your sales into the state exceed the threshold, you have nexus. This is simpler to track but may capture smaller sellers with high-value transactions earlier than transaction-count approaches.

Transaction-only thresholds focus on volume rather than value. Some states use only a transaction threshold—if you make more than a certain number of sales into the state, you have nexus regardless of total revenue. This catches high-volume, low-value sellers who might otherwise avoid nexus.

Higher thresholds reduce compliance burden. California, New York, and a few other large states use $500,000 thresholds, reflecting their large economies and desire not to burden smaller sellers. These states represent significant markets, so the higher threshold still captures most significant sellers.

Lower thresholds have been controversial. Some smaller states initially adopted very low thresholds ($10,000 or $25,000) to capture more sellers. Some were challenged in court as unduly burdensome on interstate commerce, though some have been upheld.

While you should always verify current thresholds, here's a general overview of how states approach economic nexus:

Most states ($100K/200 transactions): The majority of states adopted the South Dakota model with $100,000 in sales OR 200 transactions. This includes major markets like Texas, Florida, Illinois, and many others. If you sell $100,001 to customers in any of these states, or make your 201st sale, you trigger nexus.

High threshold states ($500K): California and New York use higher thresholds of $500,000. These large states represent significant markets, so even with higher thresholds, most substantial sellers will eventually exceed them. The benefit is that small businesses can sell into these states without immediate compliance burdens.

Special threshold states: Some states have unique thresholds or calculations. Massachusetts uses $100,000 with 3 separate sales for tangible personal property. Some states calculate thresholds based on taxable sales rather than gross sales. Understanding your specific obligations requires checking each state's rules.

No sales tax states: Five states—Alaska, Delaware, Montana, New Hampshire, and Oregon—don't have statewide sales tax. Some allow local sales taxes, but the compliance landscape is different. Alaska allows local option taxes; Delaware has no sales tax; Montana has no statewide tax but allows local option; New Hampshire and Oregon have no sales tax at all.

Given their market size, understanding thresholds for major states is particularly important for most businesses.

California uses a $500,000 threshold—higher than most states. The threshold applies to gross sales (not just taxable sales), and there's no transaction count component. As the largest state economy, California represents a huge market, so most businesses selling to California customers will eventually exceed this threshold.

New York similarly uses a $500,000 threshold. The threshold applies to total receipts, and there's no transaction minimum. Combined with strong economic activity in the state, most businesses targeting the national market will eventually exceed this threshold.

Texas uses the common $100,000/200 transaction threshold. With no state income tax, Texas has a large and active business community, making it an important market. The combination threshold means you could trigger nexus either through many transactions or through significant revenue.

Florida also uses the standard $100,000/200 transaction approach. As a large state with significant tourism and business activity, Florida represents an important market for many businesses. The threshold is straightforward to track.

Illinois uses the South Dakota model with $100,000 or 200 transactions. The threshold applies to gross receipts from sales of tangible personal property. Services may be treated differently depending on the specific service.

Pennsylvania uses $100,000 in gross sales OR 200 separate transactions. The threshold is relatively straightforward and mirrors the common approach used by most states.

Given the complexity of multiple thresholds across multiple states, tracking your position requires systematic approaches.

Implement state-level sales tracking from day one. Even if you're small now, tracking sales by destination state provides the foundation for future nexus analysis. Configure your sales systems to capture customer location for every transaction.

Calculate cumulative position throughout the year. Most states use a rolling 12-month look-back to determine nexus. Track your rolling 12-month sales to each state, updating monthly or quarterly as new sales data comes in.

Set internal alerts for threshold proximity. Create alerts at 75% and 90% of threshold levels. This gives you time to register before exceeding the threshold rather than scrambling after the fact. Proactive registration demonstrates good faith compliance.

Consider nexus tracking automation. Sales tax automation platforms include nexus monitoring that tracks your position across all states automatically. They can alert you when thresholds approach and help you register in advance.

Document your analysis. Document your threshold tracking and nexus determinations. If you're audited, documentation demonstrates your compliance efforts and can affect penalty assessments.

Review quarterly at minimum. Threshold tracking isn't a one-time exercise. Sales patterns change, new states become relevant, and thresholds themselves may change. Regular review ensures your compliance position remains current.

Several special considerations affect threshold analysis that you should understand.

Look-back periods vary by state. Most states use a rolling 12-month look-back—if your rolling 12-month sales exceed the threshold, you have nexus now. Some states use calendar year only—you have nexus if your prior calendar year sales exceeded the threshold. Understanding which approach each state uses affects how you track.

What counts as a transaction varies. Some states count each invoice; others count each line item; still others have unique definitions. The distinction between 199 and 200 transactions can be critical, so understand how each state defines a transaction.

Gross vs. taxable sales matters. Some states count all gross sales toward the threshold; others count only taxable sales. If your sales into a state are mostly exempt, you might exceed a gross sales threshold before a taxable sales threshold.

Marketplace sales may be excluded. If you're a seller on marketplaces, some states exclude marketplace sales from your threshold calculation because the marketplace may be responsible for collecting tax. However, you still have nexus if direct sales exceed thresholds.

Service thresholds differ from goods. Some states have different thresholds for services than for tangible personal property. If you primarily sell services, verify the threshold applies to your situation.

Prior year carryforward doesn't apply. Thresholds reset each year in most states. If you exceeded the threshold last year, you have nexus this year regardless of this year's sales. However, if you didn't exceed last year but do this year, you trigger nexus going forward.

Understanding threshold variations can inform your business strategy, particularly for businesses that sell nationally.

Prioritize high-threshold states early. If you're allocating sales effort, states with higher thresholds (California, New York) may allow you to delay compliance while you focus on other markets. This is particularly relevant for pre-revenue or early-revenue companies.

Consider customer concentration. If you have a few large customers in high-threshold states, you might stay below thresholds longer. If you have many small customers in standard-threshold states, you might trigger nexus faster.

Plan for threshold eventualities. Eventually, as your business grows, you'll likely trigger nexus in most states. Planning for this—building systems, budgeting for compliance costs, establishing processes—makes the transition smoother than scrambling.

Evaluate voluntary registration benefits. Registering in a state before triggering nexus has advantages—it demonstrates good faith, can limit penalty exposure if you later discover earlier nexus, and gives you experience with that state's rules. For strategically important states, early registration may be worthwhile.

Factor compliance costs into pricing. Once you trigger nexus in a state, you incur compliance costs—registration, filing, potentially automation. Factor these costs into your pricing strategy for customers in those states.
