Wayfair Compliance: Complete Guide for Remote Sellers in 2026

The Wayfair Decision Changed Everything

The 2018 South Dakota v. Wayfair Supreme Court decision fundamentally altered the sales tax landscape for remote sellers. No longer do you need a physical presence to trigger tax obligations.

What is Economic Nexus?

Economic nexus requires out-of-state sellers to collect sales tax when their sales exceed certain thresholds in a state, regardless of physical presence.

Common Economic Nexus Thresholds

• $100,000 in annual sales
• 200 transactions per year

Some states use different thresholds. Check each state’s requirements.

Who Must Comply?

You likely have Wayfair compliance obligations if you:

• Sell products online to multiple states
• Exceed $100,000 in sales in any state
• Process 200+ transactions in any state
• Use marketplace platforms (Amazon, eBay, etc.)

State-by-State Requirements

Since the Wayfair decision, all states with sales tax have adopted economic nexus laws. Each state has its own thresholds and effective dates.

Compliance Checklist

1. Analyze sales data by state
2. Identify nexus-triggering states
3. Register for sales tax permits
4. Configure tax calculation systems
5. Establish filing procedures
6. Maintain ongoing compliance

Penalties for Non-Compliance

States are aggressively enforcing economic nexus. Penalties can include:

• Unpaid taxes plus interest
• Substantial penalties
• Audit costs
