AliExpress and Overseas Suppliers: Sales Tax Rules for US Drop Shippers

Key Takeaways

• As a US drop shipper selling goods sourced from AliExpress or other overseas suppliers, you can still owe US sales tax based on where your customer receives the product.
• Most states require sales tax collection once you hit an “economic nexus” threshold, commonly $100,000 in sales or 200 transactions in a state (but thresholds vary).
• Marketplace sales (for example, when the marketplace collects tax) are often treated differently than direct website sales—track each channel separately.
• Import charges, customs duties, and shipping can affect what’s taxable, but the sales tax rules depend on the customer’s state and your nexus.

Drop shipping from AliExpress and other overseas suppliers can feel “international,” but US sales tax is usually driven by where your customer is located and how you sell. This guide explains the practical rules US drop shippers use to decide when to register, when to collect, and what to keep in your records.

Do US drop shippers buying from AliExpress have to collect sales tax?

Yes—often. If you make retail sales to customers in a state where you have nexus, you generally must collect that state’s sales tax (and any local taxes) at checkout and remit it on the schedule required by that state.

What creates sales tax “nexus” for an overseas-supplied drop shipping business?

Nexus is the connection that allows a state to require you to register and collect sales tax. For AliExpress/overseas-supplier drop shipping, nexus most commonly comes from:

• Economic nexus: You exceed a state’s sales threshold into that state during the current or prior calendar year (many states use $100,000 in sales, some use $500,000, and many have removed the 200-transaction test).
• Physical nexus: You (or your business) have an office, warehouse, employee, or other physical presence in the state.
• Inventory nexus: You store inventory in the state (including inventory held by a third party). Many drop shippers don’t hold inventory, but it can happen if you use US-based fulfillment later.

Does it matter that the supplier is overseas?

The overseas supplier location does not remove your obligation to collect sales tax when your business has nexus with the customer’s state. Sales tax is focused on the retail sale to the end customer and the destination where the product is delivered.

When do economic nexus thresholds start applying to drop shippers?

Economic nexus rules stem from the US Supreme Court’s South Dakota v. Wayfair decision (June 21, 2018). Since then, nearly every state with a sales tax has adopted an economic nexus standard. For drop shippers, this means you may need to register even with no physical presence—if your sales into a state cross that state’s threshold.

Common economic nexus thresholds (examples)

How to track thresholds if you sell on multiple channels

• Separate marketplace vs. direct sales: Marketplace sales may be collected by the marketplace facilitator, while direct website sales are typically your responsibility.
• Track by ship-to state: Use the delivery address state as the key for threshold tracking.
• Use gross receipts: Many states measure economic nexus on gross sales shipped to that state before refunds; document your method consistently.

Who collects sales tax in a drop shipping transaction: you, the marketplace, or the supplier?

In most US drop shipping scenarios, the party that collects sales tax is based on the sales channel and who is treated as the retailer to the customer.

Scenario A: You sell on a marketplace (marketplace facilitator rules)

If you sell through a marketplace that qualifies as a marketplace facilitator, the marketplace often has the legal duty to collect and remit sales tax for orders shipped to many states. In those cases:

• You may still need to register in some states depending on your other activities.
• You should keep marketplace tax reports showing tax collected, ship-to states, and order totals.
• Your direct website sales (if any) still need separate nexus tracking.

Scenario B: You sell on your own website (you are the retailer)

When you sell direct, you are typically the retailer—even if the product ships from an overseas supplier. If you have nexus in the customer’s state, you collect sales tax at checkout and remit it under your sales tax permit.

Scenario C: Your supplier ships from the US and charges you sales tax

Some drop shippers source from US-based wholesalers or distributors. If the supplier treats the sale to you as a wholesale transaction, the supplier may ask for your resale certificate. If you don’t provide it, you may be charged sales tax on your purchase—then you could also be required to collect tax from the customer, creating a margin problem. The fix is usually having the right resale documentation on file before you scale.

What’s taxable for overseas drop shipping (item price, shipping, duties, and “processing fees”)?

Tax base basics

States generally tax the retail selling price of taxable goods. What’s included in the taxable base depends on the ship-to state’s rules and how charges are presented on the invoice/checkout.

Item price

For most states, the item price is the starting point for sales tax on taxable tangible personal property.

Shipping and handling

Shipping taxability varies by state. Some states tax shipping charges when they’re part of the sale of taxable goods; others exempt separately stated delivery charges. If you ship nationwide, set your checkout to handle state-by-state rules (or use a tax engine) rather than applying one blanket approach.

Customs duties and import taxes

Import duties and customs-related charges are not “sales tax,” but they can still affect the total amount your customer pays. Whether they become part of the taxable sales price can depend on whether the customer is paying you for those charges as part of the sale versus paying a carrier directly at delivery. Keep your billing presentation consistent and retain order documentation.

Recordkeeping checklist (practical and audit-friendly)

• Invoice/receipt: Item, quantity, and selling price.
• Ship-to address: Full destination details to support the tax rate and jurisdiction.
• Tax charged: State and local tax amounts (if collected).
• Shipping charges: Separately stated vs. bundled (match your tax settings).
• Marketplace reports: If a marketplace collected tax, retain the order-level tax detail.

Resale certificates and wholesale sourcing for drop shippers

Many drop shippers start with overseas suppliers (where US resale certificates are usually not relevant) and later add US wholesalers for faster shipping. When you buy inventory for resale from a US supplier, you may need to provide a resale certificate that matches the ship-from/ship-to state rules.

Common requirements suppliers ask for

• Your legal business name and address
• Sales tax permit number (often state-specific)
• Description of items purchased for resale
• Signature and date (some accept digital signatures)

Why drop shippers should separate “permit states” from “non-permit states”

If you are registered in 10 states, you’ll issue resale certificates only where you are allowed and where the supplier’s rules support it. Maintain a simple matrix: registered states, permit numbers, certificate forms used, and renewal requirements (if any).

Process: How to set up sales tax collection for AliExpress drop shipping

Step 1: Map your sales channels

• Marketplace-only
• Direct website-only
• Hybrid (marketplace + direct)

Step 2: Track economic nexus monthly

Use a rolling report by ship-to state showing gross sales and transaction counts. A monthly cadence helps you avoid crossing a threshold and missing the first required collection period.

Step 3: Register in the states where you have nexus

Once you meet a state’s threshold or have physical/inventory nexus, register for a sales tax permit before collecting tax. Many states treat collecting before registration as a compliance problem.

Step 4: Configure tax calculation and invoices

• Apply destination-based rates where required
• Decide how to present shipping (separately stated if your system supports it)
• Confirm how discounts are taxed in each state
