US Sales Tax Economic Nexus: 50-State Threshold Guide (2026)

Ever since the Supreme Court's landmark 2018 ruling in South Dakota v. Wayfair, Inc., remote retailers, direct-to-consumer (DTC) brands, and digital SaaS providers must collect and remit state sales tax once their revenue or order volume crosses statutory benchmarks known as Economic Nexus.

In 2026, state departments of revenue have continued fine-tuning their enforcement guidelines, with over 15 states officially eliminating transaction-count thresholds (such as 200 individual orders) to focus exclusively on gross or retail sales volume. To calculate your destination-based tax obligations across all 50 states, use the FeeKit US Sales Tax Hub.

The Standard Economic Nexus Benchmarks#

While rules vary across all 45 states with general sales tax regimes, the majority of states follow one of three architectural models:

State Deep Dives: Major Commercial Hubs#

1. California Economic Nexus#

California enforces a clean $500,000 gross sales threshold delivered into the state during the preceding or current calendar year. There is zero transaction count threshold. Remote sellers who cross $500,000 must register with the California Department of Tax and Fee Administration (CDTFA) and collect base state sales tax (7.25%) plus applicable district taxes ranging up to 10.25%.

2. Texas Single Local Tax Option#

Texas utilizes a $500,000 total revenue threshold from sales of tangible personal property or services into Texas during the prior 12 months. Remote sellers can elect to collect a flat Single Local Tax (SLT) rate of 1.75% on top of the 6.25% state rate, rather than tracking hundreds of individual city and transit district boundaries.

3. New York Multi-Criteria Nexus#

New York enforces a dual condition: sales of tangible personal property delivered into the state must exceed $500,000 AND 100 separate transactions in the previous four quarters. Crossing revenue without crossing transactions does not trigger nexus.

4. Florida Economic Nexus ($100,000)#

Florida enforces a standard $100,000 remote sales threshold for taxable tangible personal property. Florida imposes a 6.00% state sales tax plus discretionary county surtaxes up to 1.50%. Check county rates with our Florida Sales Tax Calculator.

Marketplace Facilitator Laws & Exclusions#

If you sell exclusively through platforms like Amazon, Shopify, eBay, or Walmart Marketplace, these platforms act as statutory Marketplace Facilitators in nearly every state. The platform calculates, collects, and remits sales tax on your behalf.

However, sales made through facilitators almost always count toward your gross threshold for direct sales on your proprietary website. For high-volume sellers:

• Analyze Amazon marketplace margins with the Amazon FBA Profit Calculator
• Model direct storefront margins with the Shopify Dropshipping Margin Calculator
• Audit total payment gateway deductions with the Stripe Fee Calculator

Compliance Roadmap for Remote Sellers#

To avoid retroactive audits, interest, and penalties:

1. Audit trailing 12-month sales by destination state monthly using our US Sales Tax Calculator.
2. Register before making taxable sales once a threshold is breached (most states provide a 30 to 60-day registration window).
3. Verify destination-based sourcing to ensure the customer's exact 9-digit ZIP code dictates local district rates.
4. Account for self-employment tax if operating as an independent entity via our Freelance 1099 Rate Calculator.
