Economic Nexus Explained — The $100k Trigger
Before 2018, a freelancer selling services or digital products to a customer in another state didn't need to collect sales tax. The Supreme Court's Wayfair decision changed everything. Today, economic nexus means you must register, collect, and remit sales tax once you hit a state's threshold — even if you've never set foot there.
In 2026, economic nexus is the single most important sales tax rule for freelancers, digital product sellers, and remote businesses. Let's break down what triggers it, what states require, and how to avoid expensive surprises.
The Two Types of Economic Nexus Triggers
Every state uses at least one of these tests — some use both:
- Sales volume test: Gross receipts of $100,000 or more in the state during the current or prior calendar year
- Transaction test: 200 or more separate transactions (regardless of dollar amount) in the state
Let me show you how this works in practice. Suppose you're a freelance designer based in Austin, Texas, with clients across the country:
| State | 2025 Gross Sales | Transactions | Nexus Triggered? |
|---|---|---|---|
| California | $145,000 | 38 | Yes ($145k > $100k) |
| New York | $82,000 | 12 | Only if $82k + 2026 sales crosses $100k |
| Illinois | $35,000 | 215 | Yes (215 transactions > 200) |
| Georgia | $58,000 | 9 | No — under both thresholds |
You triggered nexus in California and Illinois. You'll need to register with both states, collect sales tax on future sales, and file returns. In California, that means collecting 7.25%+ state tax plus any local district taxes (which can push the total to 9.25% or more in some areas). In Illinois, the state rate is 6.25% plus local taxes.
2026 Nexus Thresholds by State
Here's a quick reference for the most important thresholds in 2026:
| State | Sales Threshold | Transaction Threshold | Notes |
|---|---|---|---|
| Alabama | $250,000 | — | Higher sales threshold |
| California | $100,000 | — | Based on sales or services |
| Colorado | $100,000 | — | Retail sales only |
| Connecticut | $100,000 | 200 | Either test triggers nexus |
| Georgia | $250,000 | — | Raised threshold in 2025 |
| Hawaii | $100,000 | — | Includes intangibles |
| Illinois | $100,000 | 200 | Both tests |
| Indiana | $100,000 | — | — |
| New York | $10,000 | — | Very low threshold — catch-all state |
| Pennsylvania | $100,000 | — | — |
| Texas | $1,000,000 | — | High threshold but local taxes apply |
| California | $100,000 | — | Most audited state |
Note: This table is a summary. Always verify the current threshold with the state's department of revenue, as thresholds can change each year.
When Digital Products and Services Count
Most states now tax digital products, including:
- SaaS subscriptions (monthly or annual)
- Digital downloads (templates, e-books, plugins)
- Streaming services and digital advertising
- Online courses and webinars
- Cloud-based services and data processing
If you're selling a $50/month SaaS subscription and have 300 New York customers, that's $180,000 in New York sales — well over the $10,000 threshold. You'd owe $14,850 in New York State tax (8.25%) plus interest and penalties for any period you missed.
Avoiding the Retroactive Audit Trap
The biggest mistake I see freelancers make is waiting until they get a notice from a state before registering. States can look back 3-4 years (sometimes more) and assess:
- Unpaid tax on all sales during the period: e.g., $100,000 in sales × 8% = $8,000 tax
- Failure-to-file penalty: 5% per month, up to 25% = up to $2,000 penalty
- Failure-to-pay penalty: 0.5% per month on unpaid tax
- Interest on all amounts (varies by state, often 6-10%)
A $100,000 sales exposure can quickly become a $12,000+ bill with penalties and interest. Voluntary disclosure agreements (VDAs) are available in most states and typically cap the lookback at 3 years with no penalties — but only if you come forward before being contacted.
Action Plan for 2026
- Pull a report of all 2025 sales by state (transaction count + dollar amount)
- Compare each state against its nexus threshold
- If you're at 75% of a threshold in any state, start collecting tax proactively
- Register using each state's online portal (most take 10-15 minutes)
- Set up automated collection using your payment processor or sales tax tool
The Bottom Line
Economic nexus isn't going away. If you're a freelancer, digital seller, or e-commerce business with out-of-state customers, you need to know your thresholds. A single $100,000 year in California or 200 transactions in Illinois can trigger full compliance requirements. The cost of non-compliance — with penalties, interest, and audit stress — vastly exceeds the cost of registering and filing on time.
