Drop Shipping and Sales Tax: The Complete Guide for Dropshippers (2026)
Last updated: April 2026
Researched by the NexusFlag Research Team
Drop shipping creates unique sales tax complications because the seller, supplier, and customer are typically in three different states. The seller must determine nexus based on where customers receive goods — not where inventory is located or where the supplier ships from.
The Drop Shipping Sales Tax Triangle
A standard retail sale involves two parties: a seller and a buyer. Drop shipping involves three: you (the seller/retailer), your supplier (the manufacturer or wholesaler), and your customer. Each relationship has a separate tax question.
You — the seller
You take the order, collect payment, and are responsible for sales tax collection from the customer.
Do you have nexus in the state where your customer is located?
Your supplier
Your supplier ships the product directly to your customer. They never interact with your customer on tax.
Are you providing a valid resale certificate so they don't charge you sales tax on your purchase?
Your customer
The customer receives the product at their address. The destination state's rules determine whether tax is owed.
Is the product taxable in the state where the customer receives it?
The core rule: In drop shipping, the retailer (you) is the seller of record. You collected the customer's money. You are responsible for charging and remitting sales tax on that transaction — not your supplier. The physical movement of goods from your supplier to your customer does not transfer your tax obligation to the supplier.
Who Collects Sales Tax in Drop Shipping?
You do. As the retailer, you collect sales tax from your customer when you process their order — the same as any other e-commerce transaction. Whether the product ships from a warehouse in Ohio or directly from your supplier in China has no bearing on your obligation to collect at checkout.
The trigger for collection is nexus in the customer's state. If you have nexus in the state where the customer lives, and the product is taxable there, you collect. If you do not have nexus, you do not collect — regardless of where the product ships from.
You have nexus in the customer's state
Collect sales tax from the customer at the rate applicable to their city/county
You do not have nexus in the customer's state
Do not collect sales tax. The customer may technically owe use tax but that is their responsibility.
You have nexus but the product is tax-exempt in that state
Do not collect. The product's taxability determines whether tax applies — nexus alone is not enough.
Your supplier is in the customer's state
Usually does not affect your obligation. You have nexus or you don't based on your own activity, not your supplier's location.
How Nexus Works for Dropshippers
Dropshippers typically have no physical inventory — they never touch the product. That means physical nexus (triggered by warehouses, employees, or inventory) is rarely an issue. The primary concern is economic nexus, which is triggered purely by sales volume into a state.
For most dropshippers, economic nexus works exactly the same as it does for any other e-commerce seller. Once your sales to customers in a state exceed $100,000 in trailing 12-month revenue (or the state's threshold, if different), you have nexus there and must register.
The supplier-as-agent gray area
A handful of states — historically including California, New York, and Texas — have argued that when a supplier physically delivers goods to a customer on behalf of the retailer, the supplier is acting as the retailer's agent in that state, potentially creating physical nexus for the retailer. This theory is contested and has not been uniformly upheld, but it is worth knowing if your supplier operates in high-volume states. If your supplier has warehouses in California, Texas, or New York, it may be worth registering in those states regardless of your sales volume there.
Nexus sources for dropshippers — ranked by likelihood
Economic nexus (sales volume)
Most common$100K in annual customer revenue is the trigger in most states. Track all sales to each state.
Home office or business address
Always presentYour home state always has physical nexus. Register there first.
Employees or contractors
Common for scaling dropshippersA VA, customer service rep, or fulfillment partner in any state creates physical nexus there.
Supplier as agent (contested)
State-dependentApplies if your supplier delivers on your behalf in CA, NY, TX. Register to avoid the risk.
Trade shows or in-person selling
Uncommon for pure dropshippersAttending a trade show or selling at a pop-up in a state creates temporary nexus in many states.
Resale Certificates: How to Avoid Being Taxed Twice
A resale certificate (also called a reseller's permit or reseller exemption certificate) is a document you provide to your supplier that exempts your wholesale purchase from sales tax. Without it, your supplier may charge you sales tax on the inventory cost, and then you must also collect tax from your customer — paying tax twice on the same product.
The resale certificate is only valid in states where you are registered as a sales tax collector. You cannot claim a resale exemption in a state where you are not registered. For dropshippers with suppliers in multiple states, this means getting registered in those states — even if your own sales volume there is below the economic nexus threshold — in order to provide a valid certificate.
How to get a resale certificate
- 1Register for a sales tax permit in the state where your supplier is located
- 2Download that state's resale certificate form from the Department of Revenue website
- 3Fill it in with your sales tax permit number and business details
- 4Send the completed form to your supplier — keep a copy
- 5Renew if your supplier requires annual recertification (some states do)
Resale certificate requirements by state (examples)
- —California: Seller must have California seller's permit
- —Texas: Texas sales tax permit required; form 01-339
- —Florida: Florida Annual Resale Certificate (AR)
- —New York: NY Certificate of Authority required
- —Ohio: Ohio STEC-B or blanket certificate
- —Washington: Washington reseller permit from DOR
Multijurisdictional resale certificates (like the MTC Uniform Sales & Use Tax Exemption Certificate) can simplify this process — a single form is accepted by multiple states. However, not all states accept the MTC certificate; California, for example, requires its own state-specific form.
Drop Shipping on Shopify, Amazon, and AliExpress
The platform you use affects what you do and do not need to handle for sales tax. Here is how the most common dropshipping setups break down.
Your own storefront — you handle everything
Shopify does not collect sales tax for you — it calculates and displays tax at checkout based on settings you configure. You must register in each nexus state and add those states in Shopify's Tax settings. Shopify Tax (available on paid plans) uses automated rooftop-level rate calculations. You still need to file and remit the collected tax to each state yourself, or use an integration like Avalara to automate filing.
Marketplace facilitator — Amazon collects for Amazon orders
If you dropship through Amazon (listing on Amazon, using suppliers to fulfill), Amazon collects and remits sales tax on those orders as the marketplace facilitator. You do not need to handle tax collection for Amazon-channel sales. However, Amazon does not affect your obligations on any other sales channel (Shopify, your own website, wholesale). FBA dropshippers should also check for physical nexus from FBA warehouse inventory. See the Amazon FBA guide.
International suppliers — same rules apply to you
If your supplier ships from China (AliExpress, Alibaba, CJ Dropshipping), the international origin does not change your US sales tax obligations. You are a US-registered business selling to US customers. Your nexus obligations are determined by where your customers are, not where your supplier is. International suppliers generally do not charge US sales tax on their orders to US-based resellers, but you should still have your resale documentation in order if your supplier has any US operations or warehouses.
Marketplace facilitator — eBay handles collection on eBay orders
eBay became a marketplace facilitator in all US states with marketplace facilitator laws by 2020. Orders sold through eBay have their sales tax collected and remitted by eBay. Like Amazon, this does not cover your sales through other channels.

Frequently asked questions about drop shipping and sales tax
Do dropshippers need to collect sales tax?
Yes, in states where you have nexus and the product is taxable. In a drop shipping arrangement, you (the seller) are responsible for collecting sales tax from your customer — not your supplier. You have nexus in a state if your sales to customers there exceed the state's economic nexus threshold (typically $100,000 in annual revenue). The fact that you never touch the physical product does not eliminate your sales tax obligation.
Does the supplier collect sales tax on my wholesale order?
Your supplier should not charge you sales tax on the inventory you purchase for resale. You prevent that by providing your supplier with a resale certificate (also called a reseller's permit or exemption certificate). The resale certificate tells your supplier: 'I am buying this to resell it, not for my own use, so you should not charge me tax.' If you fail to provide a resale certificate and your supplier charges you sales tax, you are effectively paying tax twice — once when you buy and once when your customer pays you.
Does my supplier's location create nexus for me?
In most states, no — simply using a supplier that is based in a state does not create nexus for you in that state. Nexus for the seller requires your own presence (physical nexus) or your own sales volume (economic nexus). However, a few states have taken the position that a drop-ship supplier acting as your agent in the state can create physical nexus for you. California, New York, and Texas have historically taken stricter positions on this. This is a gray area that has not been uniformly resolved.
What platform should dropshippers use to handle sales tax automatically?
Shopify with Shopify Tax (or a third-party app like Avalara or TaxJar) handles most dropshipping setups well. You configure nexus states in your tax settings and the platform collects automatically at checkout. The key step that platforms cannot do for you is registering with each state's Department of Revenue — you must do that before you start collecting. Amazon and eBay collect sales tax on orders placed through their marketplaces, but if you also run a standalone Shopify store, you are responsible for that channel independently.
