Federal income tax dominates freelancer conversations, but state sales tax nexus can surprise consultants who sell templates, workshops, or shipped goods nationwide. Nexus means a sufficient connection to a state that requires registration, collection, and remittance of sales tax on taxable transactions.

1. Types of nexus

Nexus type	Trigger examples
Physical	Office, employee, inventory, frequent travel
Economic	Remote sales above state threshold
Marketplace	Selling via Amazon, Etsy (platform may collect)
Affiliate / click-through	Some states (narrower after reforms)

2. Economic nexus snapshot (illustrative)

Many states use roughly $100,000 in sales or 200 transactions as a common economic nexus pattern—but thresholds and whether transactions count differ. Always read the current state statute.

State (example)	Common threshold pattern	Notes
California	$500,000+ sales	Higher bar than many states
Texas	$500,000+ sales	Services rules evolving
New York	$500,000 and 100 transactions	Both tests may apply
Illinois	$100,000 or 200 transactions	Classic post-Wayfair model

3. Services vs goods

A freelance attorney’s legal fees are often exempt from sales tax. A photographer selling prints and digital packs may trigger tax on tangible personal property and digital goods depending on state definitions. IT consultants implementing on-site hardware may create nexus through installation activities.

4. Compliance workflow

1. Map where customers and inventory are located.
2. Classify each offering (taxable vs exempt) per state.
3. Monitor rolling 12-month sales by state.
4. Register before collecting—voluntary disclosure may help if late.
5. File returns on each state’s cadence (monthly, quarterly, annual).

5. Marketplace facilitators

If you sell only through a marketplace that collects tax on your behalf, your obligations may differ—but services billed directly to clients still fall on you.

6. Penalties and audits

States share data and use economic nexus questionnaires. Failure to register after crossing a threshold can produce back taxes, interest, and penalties even if you never stepped foot in the state.
