Sales tax compliance is the most overlooked liability in your e-commerce clients’ businesses.
Since South Dakota v. Wayfair (2018), economic nexus means e-commerce sellers owe sales tax in states they’ve never set foot in. most of your small business clients don’t know which states they’ve crossed the threshold in. we track it, flag it, and handle the filings. Pair with tax return preparation, payroll, or a full CPA firm engagement.
Economic nexus — what it means for your clients and why it matters now.
Before 2018, a business only owed sales tax in states where it had physical presence — an office, a warehouse, an employee. the Wayfair ruling changed that permanently. now a business can owe sales tax in a state simply by selling enough there.
The problem: most small e-commerce businesses have crossed nexus thresholds in multiple states without realising it. and most CPA firms don’t have the bandwidth to proactively track 50 state thresholds for every client. we do.
| State | Threshold | Notes |
|---|---|---|
| Most states | $100K or 200 txns | Standard post-Wayfair threshold |
| California | $500K revenue | Revenue only — no transaction count |
| New York | $500K + 100 txns | Both conditions must be met |
| Texas | $500K revenue | Revenue only |
| Florida | $100K revenue | Effective July 2021 |
| Kansas | No threshold | Any sales = nexus |
| Amazon FBA states | Varies | Inventory location creates physical nexus |
