Drop Shipping Nexus Trap: Your Supplier's Warehouse May Create Physical Nexus Even Though You've Never Visited the State

The Three-Party Drop-Ship Relationship and Who Owns Nexus Risk

A drop-ship transaction involves three parties: the retailer (you), the supplier (who holds inventory and ships product), and the customer (who places the order on your website). The customer buys from you. You transmit the order to the supplier. The supplier ships directly to the customer. You never touch the product.

This arrangement is efficient — no warehouse lease, no inventory carrying costs, no packing tape. But it creates a tax problem that most drop shippers don't see coming.

The question states ask is: whose physical presence is that warehouse? The supplier owns and operates it. But when the supplier stores goods earmarked for your orders, picks and packs your products, and ships them under your brand to your customers, several states conclude that the supplier is acting as your agent. And an agent's physical presence is attributed to the principal — meaning the supplier's warehouse becomes your nexus trigger.

This is the same agency-nexus principle that applies to remote employees creating physical nexus. The person (or facility) doesn't need to be on your payroll or your lease. They just need to be conducting business on your behalf within the state.

States That Treat Supplier Warehouses as Creating Nexus for the Retailer

Not all states apply agency-nexus principles to drop-ship suppliers equally. The treatment falls into three broad categories.

Broad Agency-Nexus States (High Risk)

These states apply expansive definitions of "agent" and have either issued guidance or taken enforcement actions specifically addressing drop-ship and 3PL arrangements:

• California: The Board of Equalization (now CDTFA) has long held that a retailer using a fulfillment center in California has nexus, even if the retailer has no other presence. California's $500,000 economic nexus threshold is one of the highest in the country — but a supplier warehouse bypasses it entirely.
• New York: New York Tax Law treats any person maintaining a place of business in the state on behalf of a vendor as creating nexus. A 3PL warehouse that fulfills your orders qualifies. New York requires both $500,000 in sales and 100 transactions for economic nexus — a high bar that many small sellers never reach. But one supplier warehouse in the state makes the threshold irrelevant.
• Georgia: Georgia applies agency-nexus rules to fulfillment operations. A supplier warehouse shipping on your behalf can establish nexus. This is the state we'll use in the worked example below.
• Pennsylvania: Pennsylvania has taken the position that using a fulfillment center in the state creates nexus. The state's $100,000 economic nexus threshold is relatively standard, but physical nexus through a 3PL kicks in with zero revenue.

Narrow or Unclear States (Lower Risk)

These states generally require a more direct connection — property you own, employees you control — before asserting physical nexus:

• Florida: Florida's nexus rules focus on the retailer's own property and employees. Using a third-party supplier's warehouse — where the supplier owns the inventory until shipment — is less likely to create nexus. However, if you own inventory stored at a Florida facility, the analysis shifts.
• Texas: Texas has historically focused on whether the retailer has its own agents or property in the state. A pure drop-ship arrangement where the supplier owns inventory and ships independently is generally not treated as creating nexus for the retailer — but Texas guidance on this point is limited.

The Critical Variable: Who Owns the Inventory?

Across all states, the ownership question matters enormously. Two scenarios:

• Supplier owns inventory until shipment: This is the classic drop-ship model. The supplier carries inventory risk, and the retailer only purchases goods when a customer order comes in. In narrower states, this arrangement is less likely to create nexus because the retailer has no property in the state.
• Retailer owns inventory at supplier's warehouse: Some retailers pre-purchase inventory and store it at a 3PL facility. This is functionally identical to Amazon FBA inventory creating physical nexus. Your property is in the state. Nearly every state treats this as physical nexus, regardless of how broad or narrow their agency definitions are.

Worked Example: $200K Shopify Seller Using a 3PL in Georgia

Let's trace the nexus implications for a real-world drop-shipping scenario.

How Drop-Ship Nexus Differs from Economic Nexus

The distinction is critical and often misunderstood. Economic nexus is about how much you sell into a state. Physical nexus through a supplier is about where your fulfillment infrastructure sits — regardless of where your sales go.

This is why the drop-ship nexus trap catches people off guard. A Shopify seller doing $200,000 in total revenue with only $4,200 in Georgia sales would never think to check Georgia's nexus rules. They're at 4% of the economic nexus threshold. But their supplier's warehouse location made the threshold irrelevant.

Supplier Indemnification Clauses: Why They Don't Eliminate Your Obligation

Many drop-ship suppliers include indemnification language in their contracts. Common versions include "Supplier will be responsible for all tax obligations arising from fulfillment activities" or "Supplier indemnifies Retailer against any state or local tax claims related to inventory storage."

These clauses are worth exactly nothing to the state of Georgia (or any other state). Here's why:

• States don't recognize private contracts: Your agreement with your supplier is between you and the supplier. The state's taxing authority comes from statute, not from your vendor agreement. If the state determines you have nexus, you owe the tax — period.
• Registration is non-delegable: You cannot outsource your obligation to register for a sales tax permit. The retailer making taxable sales into a state where it has nexus must register. Your supplier cannot register "on your behalf" in a way that satisfies this requirement.
• Collection obligation falls on the seller: Sales tax is collected from the buyer by the seller. You are the seller. Your supplier is not a party to the retail transaction. The state holds you responsible for collecting the tax at the point of sale.

An indemnification clause only gives you a contractual remedy: if you pay Georgia $500 in back taxes because of your supplier's warehouse, you can potentially sue the supplier to recover that $500. But you still owed the $500 to Georgia. And in practice, enforcing indemnification against a supplier who may be overseas or undercapitalized is often not worth the cost.

When Marketplace Facilitator Laws Absorb the Risk — and When They Don't

Marketplace facilitator laws have been a genuine relief for drop shippers who sell through platforms like Amazon, Walmart, and Etsy. Under these laws, the marketplace is responsible for collecting and remitting sales tax on behalf of third-party sellers. All 46 states with a sales tax now have marketplace facilitator laws in place.

Here's where the protection ends:

Covered: Sales Through Qualifying Marketplaces

If HomeGlow sells candles through Amazon, Amazon collects and remits Georgia sales tax on those sales. HomeGlow doesn't need to worry about Georgia nexus for Amazon-channel revenue — the Georgia marketplace facilitator rules shift the obligation to Amazon.

NOT Covered: Direct-Channel Sales

HomeGlow's Shopify store is not a marketplace facilitator. Shopify does not collect or remit sales tax on your behalf. Every sale through your own website is your responsibility. If you have nexus in Georgia through your supplier's warehouse, you must collect Georgia sales tax on every Shopify sale shipped to a Georgia address.

This creates a common and dangerous split: sellers assume that because Amazon "handles the tax," they don't need to think about nexus at all. But their direct channel — often 30–60% of revenue for established brands — remains fully exposed.

The Hybrid Seller Problem

Many drop shippers sell through multiple channels: Amazon, Etsy, their own Shopify store, maybe Walmart Marketplace. Marketplace facilitator laws cover the platform sales. But the direct sales require the seller to register, collect, and remit on their own. If your supplier's warehouse creates nexus in five states, you may need to register in all five — even if 80% of your revenue flows through platforms that already handle the tax.

Practical Steps for Drop Shippers

1. Know Where Your Suppliers Operate

Before signing with a 3PL or drop-ship supplier, ask where their warehouses and fulfillment centers are located. Map those locations against the states that apply broad agency-nexus rules. If your supplier operates from California, New York, Georgia, or Pennsylvania, assume nexus until you have specific guidance otherwise.

2. Clarify Inventory Ownership

Determine whether you own inventory at the supplier's warehouse (consignment or pre-purchase model) or whether the supplier owns it until the order ships (true drop-ship model). If you own it, you have physical nexus in nearly every state. If the supplier owns it, your nexus risk depends on the state's agency-nexus rules.

3. Don't Rely on Indemnification

Negotiate indemnification clauses for financial protection, but do not treat them as a substitute for registration and compliance. The state will come to you first — not your supplier.

4. Separate Marketplace and Direct-Channel Obligations

Track your sales by channel. For marketplace sales, verify that the platform is remitting tax correctly. For direct-channel sales, determine whether you have nexus (physical or economic) in each state and register accordingly.

5. Use Voluntary Disclosure If You're Behind

If you've been drop shipping for years without registering in states where your supplier operates, consider a voluntary disclosure agreement before registering. VDAs typically limit the lookback period to three or four years and waive penalties entirely — a significant savings compared to a state-initiated audit that can reach back further and impose penalties of 25% or more.
