Economic Nexus Threshold by State for 2026: A Complete Business Guide
Understanding the economic nexus threshold by state is essential for any business selling goods or services across state lines in 2026. Since the landmark South Dakota v. Wayfair Supreme Court decision in 2018, states have implemented varying economic nexus laws that require remote sellers to collect and remit sales tax once they exceed specific revenue or transaction thresholds.
For business owners and tax professionals navigating this complex landscape, staying current with each state’s requirements is critical for maintaining compliance and avoiding costly penalties. This comprehensive guide breaks down everything you need to know about economic nexus thresholds for 2026.
What Is Economic Nexus?
Economic nexus is a tax collection obligation based on a business’s economic activity within a state, regardless of physical presence. Before 2018, companies only needed to collect sales tax in states where they had a physical presence—such as offices, warehouses, or employees. The South Dakota v. Wayfair decision fundamentally changed this landscape, allowing states to require sales tax collection from remote sellers who exceed certain economic thresholds.
Today, nearly every state with a sales tax has implemented economic nexus laws, each with its own specific thresholds and requirements. Understanding these variations is crucial for businesses engaged in interstate commerce.
Common Economic Nexus Threshold Models
Most states follow one of three primary threshold models for economic nexus:
1. The $100,000 Revenue Threshold
Many states require remote sellers to collect sales tax once their annual gross revenue from sales into the state exceeds $100,000. This is one of the most common thresholds and is used by states including California, New York, and Florida.
2. The $100,000 or 200 Transactions Threshold
The original South Dakota model, adopted by numerous states, requires sales tax collection if a business has either $100,000 in annual sales OR 200 or more separate transactions into the state. This dual threshold approach captures both high-value, low-volume sellers and low-value, high-volume sellers.
3. The $500,000 Revenue Threshold
Some states, like California and Texas, have set higher thresholds to reduce the compliance burden on smaller sellers. California requires collection only after exceeding $500,000 in annual sales, while Texas has a similar threshold.

Special Considerations for 2026
Marketplace Facilitator Laws
In addition to economic nexus, most states now have marketplace facilitator laws that require platforms like Amazon, eBay, and Etsy to collect and remit sales tax on behalf of third-party sellers. If you sell through these platforms, they may handle sales tax collection for you, but you’re still responsible for understanding your nexus obligations for direct sales.
Remote Seller Compliance
For businesses selling across multiple states, tracking economic nexus thresholds requires robust systems. Many companies utilize sales tax automation software to monitor sales by state and ensure timely registration when thresholds are approaching.
Registration Timing
Once you exceed a state’s economic nexus threshold, you typically must register for a sales tax permit and begin collecting tax. Most states require registration within 30-60 days of exceeding the threshold, though requirements vary. Some states require immediate collection upon crossing the threshold.
How to Determine Your Economic Nexus Obligations
To ensure compliance with economic nexus threshold by state requirements, follow these steps:
- Track Sales by State: Monitor your gross revenue and transaction count for each state where you make sales.
- Review Thresholds Regularly: Check each state’s current requirements, as thresholds can change.
- Register Promptly: Once you exceed a threshold, register for a sales tax permit in that state.
- Implement Collection Systems: Update your e-commerce platform or POS system to collect the appropriate tax rates.
- File Returns: Submit sales tax returns according to each state’s filing schedule.

Penalties for Non-Compliance
Failing to comply with economic nexus laws can result in significant penalties, including:
- Back taxes owed on uncollected sales tax
- Interest charges on unpaid tax liabilities
- Penalties ranging from 5% to 25% of the tax due
- Potential criminal charges for willful tax evasion
Many states offer voluntary disclosure programs that allow businesses to come into compliance with reduced penalties. If you’ve exceeded thresholds without collecting tax, consult a tax professional immediately.

Conclusion

With most states requiring sales tax collection once you exceed $100,000 in annual sales or 200 transactions, even moderately successful e-commerce businesses may find themselves with multi-state tax obligations.
As we move through 2026, staying informed about each state’s specific requirements and maintaining accurate sales tracking systems will be essential for compliance. Whether you handle sales tax in-house or work with a tax professional, proactively managing your economic nexus obligations protects your business from costly penalties and ensures you can focus on growth rather than tax disputes.
