That assumption gets businesses into trouble. A dropshipping retailer can still face U.S. sales tax collection, registration, filing, and recordkeeping duties, even without a warehouse or a single box in hand.
Since the Supreme Court's 2018 ruling in South Dakota v. Wayfair, Inc. removed the physical-presence requirement for sales tax collection, states can require out-of-state sellers to collect tax based purely on sales volume. That single decision reshaped how dropshippers, marketplace sellers, and cross-border founders need to think about compliance.
Your actual obligation depends on several moving parts: your nexus, your supplier's nexus, where the customer takes delivery, whether the product is taxable, whether a marketplace is involved, and each state's specific drop-shipment rules. Here's how those pieces fit together.
Key Takeaways
- Nexus, not inventory ownership, determines whether you must collect sales tax
- Retailer and supplier can each carry separate collection duties on the same order
- A resale certificate can exempt your supplier purchase, not your retail sale
- Marketplace facilitator laws shift some, not all, collection responsibility
- State thresholds and product taxability rules change—verify current requirements before relying on old figures
How a Dropshipping Transaction Works for Sales Tax Purposes
Dropshipping looks like one sale from the customer's side. For sales tax purposes, it's actually two.
Two Transactions, One Order
Picture a customer in Ohio buying a lamp from your online store. You never see the lamp. Instead:
- The customer buys from you (the retailer) - this is the retail sale, and it's typically what triggers sales tax.
- You buy from your supplier, who ships the lamp directly to the customer - this is a separate wholesale or resale transaction.
New York's tax authority is explicit about this structure, describing dropshipping arrangements as two distinct transactions for sales tax purposes: the supplier-to-retailer sale and the retailer-to-customer sale. Each has its own taxability analysis and potentially a different taxing state involved.
The four roles worth tracking:
- Retailer - the business that took the customer's order and payment
- Supplier - the manufacturer or wholesaler that ships the product
- End customer - the person receiving the product, in the destination state
- Taxing authority - the state (and sometimes city or county) with jurisdiction over the delivery address
Here's the part that trips people up: the supplier physically shipping the box does not automatically shift your sales tax obligation onto them. Responsibility depends on which party has nexus in the destination state, not on who prints the shipping label.
Sales Tax Is Not the Only Tax in Play
Dropshippers often lump every possible tax bill into "sales tax." They're not the same thing:
- Sales tax applies to the taxable retail sale to the end customer
- Use tax applies when a customer buys something tax-free and the state expects them to self-report it
- Income tax is based on business profits, unrelated to whether a specific sale was taxed
- Customs duties apply to goods crossing an international border, entirely separate from state sales tax
Confusing these categories is a fast way to either overpay unnecessarily or miss a real filing requirement.
Sales Tax Nexus: When Does a U.S. Dropshipper Need to Register?
Nexus is the legal hook. Without it, a state has no authority to make you collect its sales tax. With it, you're on the hook for registration, collection, filing, and remittance.
Physical Presence Still Counts
The traditional test looks for a tangible connection to the state:
- An office, warehouse, or employee located there
- Inventory stored there, including inventory a marketplace facilitator holds on your behalf
- An agent or representative conducting business on your behalf
- Other in-state activity tied directly to your operations
A word of caution: your supplier's warehouse isn't automatically your warehouse. Nexus triggers generally attach to the retailer's own property or attributed activity, not simply the fact that another company's truck delivered the box.
Economic Nexus After Wayfair (2018)
Before 2018, physical presence was required before a state could force collection. The Supreme Court's decision in Wayfair removed that requirement, allowing states to impose "economic nexus" based purely on sales volume or transaction count.
The Court examined South Dakota's threshold at the time, more than $100,000 in annual sales or 200 separate transactions, but that figure was never meant to become a nationwide standard.
States have since set their own numbers. Some use a dollar test alone; others combine a dollar test with a transaction count; several have dropped the transaction-count option in recent updates. That means checking current thresholds state by state, not applying one rule of thumb everywhere.
| What to check | Why it matters |
|---|---|
| Threshold type | Sales-dollar test, transaction-count test, or both |
| Measurement period | Calendar year, rolling 12 months, or a specific lookback |
| Included sales | Gross sales vs. taxable sales only - resale and exempt sales may or may not count |
| Effective date | When registration actually becomes required after crossing the line |
What Else Feeds the Nexus Analysis
Your nexus picture isn't limited to your office lease. Factor in:
- Direct sales into each state
- Fulfillment arrangements with suppliers or third-party logistics providers
- Marketplace sales through Amazon, Etsy, or similar platforms
- Returns processed in a given state
- Affiliate or referral relationships generating in-state sales
Crossing a threshold mid-year doesn't automatically mean you owe tax retroactively on every prior sale. Registration timing and procedures differ by state, so confirm specifics with that state's revenue department before assuming a retroactive liability.
One more thing: thresholds, filing frequencies, and product taxability rules change year to year. Build a recurring nexus review into your calendar rather than checking once and moving on.
Who Collects and Remits Sales Tax in a Dropshipping Transaction?
Once you know who has nexus where, the collection question gets more concrete. Four scenarios cover most dropshipping situations.
Scenario 1: Retailer Has Nexus in the Customer's State
This is the simplest case. If you have nexus in the destination state, you generally:
- Register for a sales tax permit before collecting
- Charge the applicable tax at checkout
- File returns on the state's assigned schedule
- Remit what you collected
Your supplier's location doesn't change this. You're the retailer of record on this sale.
Scenario 2: Supplier Has Nexus, Retailer Doesn't
If you lack nexus but your supplier has it in the destination state, the supplier may carry obligations under that state's drop-shipment rules. Depending on the state, they might need to:
- Collect tax directly from your customer
- Charge tax on their sale to you unless you provide a valid resale certificate
States don't handle this identically. California, for example, treats the drop shipper as liable for tax on the retail sale if the out-of-state "true retailer" doesn't hold a California permit.
When the true retailer's actual selling price isn't otherwise documented, CDTFA offers a formula based on a markup over the drop shipper's charge, according to CDTFA's drop-shipment guidance. That's meaningfully different from how other states approach the same fact pattern.
Scenario 3: Both Parties Have Nexus
This is where things get messy. If you and your supplier both have nexus in the destination state, get clarity in writing on:
- Who actually collects tax from the customer
- How tax appears on the customer-facing invoice
- How you avoid the customer being charged tax twice
Skipping this conversation is how double collection, or missed collection, happens.
Scenario 4: Neither Party Has Nexus
If neither you nor your supplier has nexus in the destination state, neither may be required to collect. That doesn't make the sale tax-free for the customer. Many states expect buyers to self-report and pay consumer use tax on untaxed purchases. Don't market a transaction as "tax-free" just because no seller collected anything at checkout.
Marketplace Facilitator Rules Add Another Layer
If you sell through Amazon, Etsy, or a similar platform, marketplace facilitator laws may shift collection duty to the platform for qualifying transactions. That doesn't erase every duty on your side. Check:
- Which states, products, and channels the facilitator actually covers
- Whether your direct website sales are handled separately from marketplace sales
- Whether you still need to register, file, or report even when the platform collects
Before your sales volume scales further, document each party's nexus position, active permits, and who's responsible for collection on every fulfillment channel you use.
A Practical Sales Tax Compliance Process for U.S. Dropshippers
Theory aside, here's a working process for staying compliant as your dropshipping business grows.
Step 1: Map Your Exposure
Start with a full inventory of where your business touches each state:
- Entity location, owners, and employees
- Supplier and warehouse locations
- Customer delivery destinations
- Sales channels: your own site, Amazon, Etsy, wholesale
- Return volumes by state
- Current and projected sales activity
Step 2: Determine Product Taxability
Taxability isn't uniform across states or product types:
- A t-shirt may be taxed differently than a digital download
- Shipping charges can be taxable in one state and exempt in another
- Bundled products and subscriptions add further complexity
Research official state guidance for each product category rather than assuming one state's rule applies everywhere.
Step 3: Register Before You Collect
Register for a sales tax permit before charging customers tax in a given state. Collecting without proper registration creates its own compliance problem in several states, sometimes worse than not collecting at all.
Step 4: Configure Your Systems
Your ecommerce store, marketplace accounts, payment processor, and accounting system all need to apply the correct tax rules, whether destination-based or origin-based. Preserve the underlying order data: addresses, amounts, and tax collected.
Losing that trail makes future filings and audits harder.
Step 5: Build a Filing Calendar
Track, for every state where you're registered:
- Filing frequency (monthly, quarterly, annual)
- Zero-return requirements, since some states expect a return even with no sales
- Payment deadlines and local or county-level returns
- Marketplace reporting requirements and amendment procedures
Verify current deadlines directly with each state; due dates and penalty structures vary widely and shift over time.
Where VJM Global Fits
Running this process across a dozen states, several sales channels, and a growing SKU list is a lot to manage alongside actually running the business.
VJM Global works with U.S. businesses and international founders selling into the American market on tax compliance reviews, accounting coordination, registrations, and ongoing reporting. That support matters most once a dropshipping operation crosses into multiple states, where tracking each state's rules becomes its own part-time job.
Resale Certificates, Exempt Sales, and Records
Resale Certificates Cover Your Purchase, Not the Final Sale
A valid resale certificate can let you buy inventory from your supplier without paying sales tax, because you're buying it to resell rather than to use.
Keep these limits in mind:
- Acceptance rules, required fields, and forms vary by state
- A certificate valid in one state will not automatically satisfy another
- Resale treatment covers your purchase from the supplier only
- It does not exempt your retail sale to the end customer
You still need to collect tax on that sale wherever you have nexus and the product is taxable.
Exemptions Vary by State and Product
There's no universal list of tax-free products in the U.S. Exemptions depend on the state, the product category, and sometimes the buyer's status (for example, reseller or nonprofit).
Check the destination state's official exemption list before assuming a product qualifies.
Recordkeeping Checklist
Keep these organized and accessible:
- Resale and exemption certificates
- Supplier agreements and invoices
- Customer and ship-to addresses
- Tax collected per transaction
- Marketplace sales reports
- Permits, filed returns, and remittance confirmations
Retention periods differ by state, but three to four years is a common baseline. Keep files audit-ready so you can show taxability decisions, nexus positions, exemptions claimed, and amounts remitted if a state asks.
Build a Repeatable U.S. Sales Tax Process
Dropshipping doesn't erase sales tax obligations. It spreads them across more parties: you, your supplier, the destination state, and sometimes a marketplace platform. Getting collection responsibility right means reviewing nexus, product taxability, and documentation together, not in isolation.
Treat compliance as an ongoing habit, not a one-time project:
- Monitor sales by state monthly, not annually
- Re-check nexus as you add channels or suppliers
- Update product taxability when you add new SKUs
- Confirm supplier documentation before assuming a purchase is exempt
- Reconcile what you collected against what you remitted
- Meet every filing deadline, including zero returns

Frequently Asked Questions
How does dropshipping get taxed?
A dropshipping sale involves two transactions: the supplier's sale to you and your sale to the customer. Nexus determines who collects tax on each one, so review your specific state and channel setup rather than applying one rule everywhere.
What items are exempt from sales tax in the US?
Exemptions vary by state, product category, and buyer type. There's no single national exemption list, so check the destination state's tax authority guidance for the product you sell.
Do I need to collect sales tax for dropshipping?
Generally yes, once you have nexus in the customer's state. Marketplace facilitator laws and your supplier's own nexus can shift part of that responsibility, so confirm the collection duty for each sales channel you use.
Who pays sales tax in a dropshipping transaction?
The customer bears the economic cost of sales tax, but the retailer, and sometimes the supplier or marketplace, carries the legal duty to collect and remit it. These are two different responsibilities.
Do I need a resale certificate for dropshipping?
A valid resale certificate can let you buy from your supplier tax-free when the goods are for resale. Requirements differ by state, and the certificate must stay current and on file to hold up during an audit.
