Does drop shipping create physical nexus for a sales tax obligation?

For most drop-shipping businesses, the supplier’s warehouse doesn’t create nexus for the retailer. Your nexus comes from your own physical presence, your inventory, your employees, your locations. The supplier’s facility is the supplier’s nexus, not yours.

But drop shipping creates its own compliance complexity that has nothing to do with physical nexus: the exemption certificate problem.

The basic nexus question for drop shippers

If you’re the retailer using a drop-ship supplier:

Your supplier ships from their warehouse directly to your customer. The warehouse is the supplier’s, not yours. Your nexus in any given state comes from your own business activity there: your own inventory locations, employees, offices, or economic nexus threshold crossings.

The fact that your supplier happens to be in Texas doesn’t make you have Texas nexus. If you have no employees, offices, inventory, or other presence in Texas, and you’re below Texas’s $500,000 economic nexus threshold, you don’t have Texas nexus, even if every order you take is shipped from your Texas-based supplier.

If you’re the supplier acting as a drop shipper:

Your warehouse creates your nexus. When a retailer sends you orders to fulfill to their customers, you’re shipping from your facility. Your physical presence in your warehouse state is your nexus. This is straightforward, your own location is the nexus trigger.

The economic nexus overlay

Even if a drop shipper has no physical nexus in a state, economic nexus thresholds still apply. If your drop-ship retailer business makes $120,000 in sales to customers in California, you have California economic nexus (once you reach California’s $500,000 threshold). The fact that a supplier fulfills those orders doesn’t change the threshold calculation.

Economic nexus is based on where the customer is located and the dollar amount of sales, not on where the goods ship from.

The exemption certificate problem

This is the real compliance challenge in drop shipping, and it’s more practically significant than the nexus question.

A standard drop-ship transaction:

1. Retailer → Supplier: Retailer purchases product at wholesale (resale exemption applies, retailer gives supplier a resale certificate)
2. Supplier → Customer: Supplier ships to end customer

The issue: The supplier may have nexus in the customer’s state; the retailer may not.

When the supplier has nexus in the ship-to state, the supplier typically needs to collect sales tax unless the retailer can provide a valid resale certificate for that state. But the retailer may not be registered in that state, they can’t issue a valid resale certificate for a state where they have no registration.

This puts the supplier in a bind:

• Collect tax from the retailer (passes cost to retailer, who isn’t collecting from their customer)
• Skip collection without a valid certificate (creates liability for the supplier)

Some states have specific provisions for this scenario; most require the supplier to collect if they have nexus and can’t obtain a valid resale certificate. Retailers managing drop shipping at scale need to understand their nexus footprint and registration status precisely, because those determine whether they can issue valid resale certificates to their suppliers.

What drop shippers need to track

If you use drop shipping as your fulfillment model:

• Your own economic nexus thresholds by state (based on where your customers are, not where your supplier is)
• Your registration status in those nexus states
• Whether your supplier has nexus in your high-volume ship-to states (determines when the exemption certificate issue arises)
• Valid resale certificates on file for states where your supplier has nexus

The exemption certificate tracking is typically the first area where drop-shipping businesses encounter compliance friction.
