If you drop ship in the United States, sales tax is your single biggest compliance risk — bigger than customs, bigger than income tax, bigger than payment processing. Three parties, two potentially taxable transactions, and up to three states with jurisdiction over a single order. Get the paperwork wrong, and your supplier charges you sales tax you legally cannot recover from your customer — vaporising your margin on every shipment.
This guide walks through every mechanic drop shippers actually need in 2026: who collects, which resale certificate to hand your supplier, the ten states that reject out-of-state certificates outright, how marketplace facilitator laws overlap with drop shipping, and how foreign sellers using US-based suppliers can stay compliant without a US bank account or Social Security number.
Reading this article takes about 40 minutes. The exact position here depends on your own facts, so it is worth confirming with the state directly or talking to us about your situation. If you’d rather skip the execution, Sales Tax Compliance USA handles the entire multi-state stack for a single fee.
What Is Drop Shipping (For Sales Tax Purposes)?
Drop shipping is a transaction where you sell a product you don’t physically hold, and your supplier ships it directly to your customer on your behalf. From a sales tax perspective, this is not one transaction — it’s two.
The three-party transaction
Three parties are involved:
- The retailer (you) — makes the sale to the end customer.
- The supplier / drop shipper — holds the inventory and physically ships the product.
- The end customer — receives the goods, pays the retail price to the retailer.
Two sales, one shipment
Legally, this single physical shipment involves two distinct sales:
- Sale #1 (wholesale): Supplier → Retailer. This is a sale for resale, which should be exempt from sales tax if the retailer provides a valid resale certificate.
- Sale #2 (retail): Retailer → End customer. This is the sale that generates sales tax liability if the retailer has nexus in the ship-to state.
Only one physical shipment moves — from supplier’s warehouse directly to the end customer — but two legally distinct transactions occurred, and each has its own sales tax analysis.
Why sales tax gets messy
Up to three states can claim jurisdiction over a single drop-ship order:
- The state where the supplier is located and from which the goods ship.
- The state where the retailer is legally domiciled or registered.
- The state where the end customer takes delivery (the “ship-to” state).
Each state has its own rules on who owes tax, whose resale certificate is acceptable, and what documentation must be retained. The interaction of three states’ rules on one order is why drop shipping is the single most-audited business model in US sales tax.
The Core Rule: Who Collects Sales Tax in a Drop Ship Scenario?
The default rule: whichever party has nexus in the ship-to state is responsible for collecting sales tax on that leg. The complication is that both the retailer and the supplier may have nexus — or only one of them may — and each combination triggers different consequences.
When the retailer has nexus in the ship-to state
This is the cleanest scenario. If you (the retailer) have nexus in the state where your customer receives the goods:
- You collect sales tax from your customer at the ship-to state’s rate.
- You give your supplier a valid resale certificate for the wholesale leg.
- The supplier does not collect tax from you.
- You remit the tax you collected to the ship-to state on your regular return.
When only the supplier has nexus in the ship-to state
This is where drop shipping becomes painful. If your supplier has nexus in the ship-to state but you (the retailer) do not:
- The supplier is required to collect sales tax on the transaction in the ship-to state.
- The supplier will attempt to accept a resale certificate from you so they don’t have to charge tax.
- If the ship-to state accepts your resale certificate, no tax is charged and the end customer owes use tax (which they almost never pay).
- If the ship-to state rejects your resale certificate (see the ten-state list below), the supplier is forced to charge you sales tax on the wholesale price — and you cannot legally pass that tax through to your customer as sales tax. It becomes a margin hit.
When neither party has nexus
If neither you nor your supplier has nexus in the ship-to state, no one is required to collect sales tax. The end customer technically owes use tax to their home state, but consumer use tax compliance is famously low. Post-Wayfair, this scenario is rarer than it used to be — economic nexus rules mean many retailers cross thresholds without realising it.
Wayfair (South Dakota v. Wayfair, Inc., 138 S. Ct. Wayfair (2018) expanded sales-tax nexus from physical presence to economic activity for sellers, meaning a retailer can trigger nexus by revenue and transaction volume alone without setting foot in the state.
Resale Certificates: The Heart of Drop Shipping Compliance
Every drop-ship relationship lives or dies on the resale certificate you give your supplier. Without a valid certificate accepted by the ship-to state, your supplier must charge you sales tax on the wholesale leg — and that tax is lost margin, not a pass-through.
MTC Uniform Certificate
The Multistate Tax Commission Uniform Sales & Use Tax Exemption / Resale Certificate is a single document accepted by roughly three-quarters of US states in some form. It’s the workhorse certificate for interstate drop shipping. A retailer registered in any US state can generally use the MTC form to buy for resale from a supplier in any state that accepts it — subject to state-specific quirks.
SST Certificate of Exemption
The Streamlined Sales Tax (SST) Certificate of Exemption is accepted by all Streamlined Sales Tax Governing Board member states. Notable SST member states in the drop-ship context include Several states—including certain Midwestern and Northeastern jurisdictions—have distinct sales tax registration and compliance regimes worth reviewing individually. If you have multi-state exposure across states like Illinois, Kansas, Louisiana, or Massachusetts, contact us for a current review. The SST certificate can be a good option when you’re dealing with multiple SST states.
Non-SST states (including California, Florida, Hawaii, Maryland, Mississippi, and Tennessee) do not accept the SST certificate. You need a different approach for them.
Home-state resale certificates
Some states accept only their own state-issued resale certificate. In those states, the only way to give your supplier tax-exempt paperwork is to register in that state and obtain that state’s own certificate.
- California does not mandate one particular form. Under CDTFA Regulation 1668 a resale certificate is valid where it carries the purchaser’s signature, name and address, a California seller’s permit number (or a sufficient explanation of why none is held), the words “for resale” and a description of the property, and the date. CDTFA-230 is the general resale certificate CDTFA publishes, and it is the safest document to hand a Californian supplier. A certificate from an out-of-state purchaser may qualify only if it timely contains all Regulation 1668 elements, including a seller’s permit number or a sufficient explanation for why the purchaser is not required to hold one. Regulation 1706 addresses drop shipments and provides specific documentation rules and exceptions, including rules for marketplace-facilitated sales.
- Florida issues the Annual Resale Certificate (Form DR-13), which is renewed each year and issued only to Florida-registered dealers.
Which certificate to give your supplier
The practical rule is simple: give your supplier whatever certificate the ship-to state will accept from you. Because drop shipments can go to any state, most drop shippers who scale beyond a few states end up needing:
- An MTC form ready for the majority of accepting states.
- An SST form for streamlined states that prefer it.
- State-specific certificates for the ten states that reject out-of-state certificates (see next section).
Suppliers are required to accept certificates in good faith and retain them typically for three to four years depending on the state. If a supplier is audited and the state rejects a certificate they accepted, the supplier may be assessed the uncollected tax — which is why sophisticated suppliers are increasingly picky about which certificates they accept.
The 10 States That Don’t Accept Out-of-State Resale Certificates
This is the single most consequential section of this guide. Roughly ten states have taken the position that they will not accept out-of-state resale certificates, or accept them only with significant limitations. If your drop shipper is located in one of these states — or ships to a customer in one of these states — your out-of-state or MTC resale certificate may be rejected, and the supplier will be forced to charge you sales tax.
The workaround is almost always the same: register in the state and obtain that state’s own certificate. But registration triggers filing obligations, which is why this decision needs careful economic analysis.
California
California maintains specific drop shipment rules that are among the more complex in the country, and the correct treatment depends on the parties involved and documentation held. If you drop ship into California, contact us for a current review. When a supplier ships tangible personal property into California to a California customer of an out-of-state retailer, the supplier can be treated as the retailer and may owe use tax on the transaction unless the out-of-state retailer is registered with the California Department of Tax and Fee Administration (CDTFA), or the wholesaler can substantiate that a valid resale certificate was received and the retail price is documented.
Practical fix: register for a California Seller’s Permit and provide CDTFA-230 to your supplier. Registration is free; the ongoing filing burden is significant given California’s California imposes a 7.25% statewide base sales and use tax rate, with district taxes added on top; the general statutory cap on combined district taxes in a county is 2%, producing a typical maximum combined rate of about 9.25% unless special legislation authorizes a higher district rate (CDTFA)..
Florida
Florida requires that a resale certificate be a valid Florida Annual Resale Certificate (Form DR-13), which is only issued to businesses that have registered for a Florida sales tax number. Out-of-state resale certificates are generally rejected by Florida suppliers because the supplier cannot rely on them for exemption.
Practical fix: register for a Florida sales tax permit via Form DR-1. Registration is free, and DR-13 is issued upon approval.
Hawaii
Hawaii doesn’t have a sales tax at all — it has the General Excise Tax (GET), which is imposed on the seller’s gross business income rather than on the buyer’s purchase. This changes drop-ship mechanics fundamentally. Hawaii does issue its own resale certificate, Form G-17, rather than accepting the multi-state forms other states rely on. GET is charged by business activity rather than on the buyer: the Hawaii Department of Taxation puts wholesaling at 0.5% and retailing at 4.0%, with a county surcharge of up to 0.5% on top of the retail rate but not on wholesaling. A supplier that applies the wholesale rate without adequate documentation carries the audit risk itself, which is why a Hawaii supplier will normally want a completed G-17 from you before it will use that rate at all. What your own supplier will accept depends on your facts, so it is worth confirming with the state directly or talking to us about your situation.
Practical fix: obtain a Hawaii GET license (Registration fees vary by state and can change, so confirm the current amount before filing. If you are registering for a new sales tax permit, contact us for a current review.) and provide it to Hawaii suppliers.
Illinois
Illinois is a Streamlined Sales Tax member state, so it accepts the SST certificate. However, Illinois has additional requirements for drop-ship documentation and generally expects an Illinois registration number on resale certificates presented to Illinois suppliers.
Practical fix: register via MyTax Illinois if you have Illinois suppliers frequently drop-shipping for you.
Louisiana
Louisiana has a complex parish-level sales tax system alongside its state tax, and its DOR generally requires Louisiana-registered suppliers to accept only Louisiana-issued resale certificates for maximum audit protection.
Practical fix: register through the Louisiana Sales and Use Tax Commission for Remote Sellers if you cross the economic nexus threshold or have Louisiana-based suppliers.
Maryland
Maryland Comptroller guidance requires suppliers to obtain a Maryland resale certificate that references the retailer’s Maryland sales and use tax account number. Out-of-state certificates without a Maryland number are typically rejected.
Practical fix: register with the Maryland Comptroller and obtain a Maryland sales and use tax license.
Massachusetts
Massachusetts requires suppliers to accept a Massachusetts Form ST-4 (Sales Tax Resale Certificate), which references a Massachusetts sales tax permit number. The state accepts SST certificates in some contexts but Massachusetts-based suppliers routinely require the ST-4.
Practical fix: register via MassTaxConnect and complete Form ST-4 for each supplier.
Mississippi
Mississippi generally requires a Mississippi-issued resale certificate for exemption. Its sales tax landscape has strict documentation requirements, and Mississippi suppliers typically won’t accept out-of-state certificates without significant risk.
Tennessee
Tennessee’s Department of Revenue requires suppliers to obtain Tennessee-specific documentation. While the SST certificate is technically accepted, Tennessee-based suppliers frequently insist on a Tennessee Certificate of Resale referencing a Tennessee sales tax account number.
Washington
Washington uses a Reseller Permit system rather than the more common resale certificate. The Washington Department of Revenue issues reseller permits only to businesses registered in Washington. Out-of-state resale certificates are not accepted for wholesale purchases from Washington-based suppliers.
Practical fix: register with the Washington DOR and apply for a reseller permit. Washington also charges Business & Occupation (B&O) tax, which is a separate wrinkle for drop-ship suppliers.
Workarounds and exceptions
For each of these states, the practical options are:
- Register in the state. This is the cleanest fix but adds a filing obligation. If your supplier ships from that state or you have material sales into that state, registration is usually worth it.
- Switch suppliers. If a supplier ships only from a state that rejects your paperwork, consider whether an alternate supplier in a friendlier state solves your problem.
- Have the supplier charge you tax. In some cases, absorbing sales tax on the wholesale price is cheaper than registering and filing ongoing returns — especially for very low-volume shipments. This is only sensible when supplier tax is genuinely trivial.
Because the calculus varies by supplier volume, product margin, and expected growth, we run this analysis as part of our nexus and registration onboarding and handle whichever registration option makes the most sense.
How Economic Nexus Applies to Drop Shipping
Post-Wayfair, you can trigger sales tax nexus in a state without ever setting foot there — purely through revenue and transaction volume. For drop shippers this matters even more than for typical e-commerce sellers, because your suppliers’ locations can independently trigger nexus for you.
Thresholds still apply to your retail sales
Every state now has an economic nexus threshold. Common examples verified in our knowledge base:
| State | Threshold | Effective |
|---|---|---|
| California | California’s economic nexus rule uses a sales-based threshold measured against combined sales of tangible personal property delivered into the state by the retailer and related persons, triggering state and district use tax registration (CDTFA). If you are approaching California’s economic nexus threshold, contact us for a current review. | 2019-10-01 |
| Florida | Florida applies an economic nexus threshold to remote sellers based on Florida-destined sales. If your Florida sales are approaching the state’s economic nexus threshold, contact us for a current review. | 2021-07-01 |
| Illinois | Illinois’ economic nexus and remittance rules for remote retailers and marketplace facilitators currently use a $100,000 or 200-transaction threshold for periods through December 31, 2025; beginning January 1, 2026, only the $100,000 cumulative gross receipts threshold (measured over the 12-month lookback) applies (IL DOR). | 2018-10-01 |
| Louisiana | Louisiana applies an economic nexus threshold to remote sellers, and the specifics of when consumer use tax versus sales tax collection applies depend on the fact pattern. If you have Louisiana sales exposure, contact us for a current review. | 2020-07-01 |
| Maryland | $100,000 or 200 transactions | 2018-10-01 |
| Massachusetts | $100,000 | 2019-10-01 |
| Kansas | Kansas has adopted an economic nexus threshold for remote sellers, but the current figure and effective date should be confirmed against Department of Revenue guidance. If you have Kansas sales exposure, contact us for a current review. | 2021-07-01 |
The threshold is measured against your retail sales into the state, regardless of who shipped the product. If your supplier drop-ships $150,000 of goods on your behalf into Florida in a calendar year, you have Florida economic nexus and must register — even though you never touched the inventory.
For our full state-by-state list, see the economic nexus thresholds guide.
Do wholesale sales count toward supplier thresholds?
States differ on whether wholesale (exempt) sales count toward the threshold calculation:
- Some states include all gross sales — including exempt sales — in the threshold measurement.
- Others measure the threshold only against retail (taxable) sales.
- Others measure it against total revenue including services.
Because state positions vary and change over time, this is one of the most common places drop shippers get caught out. If you’re unsure whether your specific sales pattern crosses a threshold in a given state, book a nexus review with us rather than guessing.
Inventory-at-supplier as physical nexus
If your drop shipper stores inventory that is specifically earmarked or consigned for you — as opposed to shipping from their general stock — you may have physical presence nexus in the supplier’s state, regardless of your revenue. This is analogous to the FBA inventory trap: holding your own inventory in a state, even indirectly through a fulfilment partner, creates physical nexus in most states.
The nexus profile depends heavily on the specific supplier arrangement and applicable state guidance. If your drop-ship arrangement involves dedicated inventory, storage under your name, or any form of consignment, contact us for a current physical-nexus review.
One important carve-out worth noting: Illinois has taken the position that inventory used solely for marketplace-facilitated fulfilment does not create physical-presence nexus for the marketplace seller. But this Illinois-specific rule applies only to marketplace-facilitator fulfilment, not to drop-ship arrangements generally. Don’t extrapolate it.
For a fuller treatment, see our sales tax nexus guide.
Sourcing Rules: Which State’s Rate Applies?
In drop shipping, the ship-to state’s rate almost always governs the retail leg of the transaction. This is called destination sourcing, and it’s the majority rule in the US.
Destination sourcing (majority rule)
Under destination sourcing, the sales tax rate is determined by where the goods are delivered. If you sell an item to a customer in Miami and your supplier ships it there, you charge Florida sales tax at the Miami rate — regardless of where you or your supplier are located.
This is why drop shippers need accurate rate lookup tools: every ship-to address can have a different combined state, county, city, and district rate.
Origin sourcing states
A minority of states use origin sourcing for intrastate sales — meaning the rate is set by the seller’s location, not the buyer’s. Historically, origin-sourcing states have included Arizona, Illinois, Missouri, Mississippi, New Mexico, Ohio, Pennsylvania, Tennessee, Texas, Utah, and Virginia (with variations).
The key point for drop shippers: origin sourcing applies almost exclusively to intrastate sales — sales where the seller and buyer are both in the same state. For interstate drop shipments (the common case), the ship-to state’s rate applies, i.e. destination sourcing.
California is a partial exception: as noted in our knowledge base, California’s sourcing rules for in-state sales differ from its treatment of district taxes, and the correct rate depends on where title transfers, where the seller operates, and the delivery location. If you need help sourcing California transactions correctly, contact us for a current review. Remote sellers into California source to the buyer’s location.
Because sourcing rules can be nuanced state-by-state — especially in origin states with intrastate complexity — if you have suppliers and customers in the same origin-sourcing state, contact us for a specific analysis.
The interstate exception
Even in origin-sourcing states, once a shipment crosses state lines, destination sourcing takes over. Under the Streamlined Sales Tax framework, all member states source interstate sales to the destination.
Practical rule of thumb: for drop shipments crossing state lines, look up the rate at the ship-to address.
Marketplace Facilitators + Drop Shipping: The Overlap
One of the most common drop-ship questions in 2026: if Amazon (or Walmart, or eBay) is already collecting sales tax on my orders, do I still need a resale certificate for my supplier? Yes — because the marketplace facilitator only handles the retail leg. The wholesale leg (supplier → you) is a separate transaction that still needs its own tax treatment.
When Amazon/Walmart/eBay collects on the retail leg
Every state now has marketplace facilitator laws requiring platforms to collect sales tax on facilitated third-party sales. Examples verified in our knowledge base:
| State | MF effective date |
|---|---|
| California | 2019-10-01 |
| Florida | 2021-07-01 |
| Illinois | Illinois’ marketplace facilitator collection obligation took effect on a specific date tied to its Leveling the Playing Field legislation; confirm the exact effective date with current DOR guidance. If you need to confirm Illinois marketplace facilitator timing, contact us for a current review. |
| Louisiana | Marketplace facilitator effective dates vary by state and have been amended in several jurisdictions. If you need to confirm a specific state’s marketplace facilitator effective date, contact us for a current review. |
| Maryland | 2019-10-01 |
| Massachusetts | Massachusetts’ marketplace facilitator collection requirement took effect on a specific date that should be confirmed against current DOR guidance. If you need to confirm Massachusetts marketplace facilitator timing, contact us for a current review. |
| Kansas | 2021-07-01 |
For a full list of states and their marketplace laws, see our marketplace facilitator guide.
Do you still need a resale certificate for your supplier?
Yes. The marketplace facilitator’s collection handles the sale from you to the end customer. It does not touch the sale from the supplier to you. That wholesale leg is a separate transaction, and unless you give your supplier a valid resale certificate, they will charge you sales tax on it.
This applies regardless of whether your final customer paid tax via Amazon, Walmart, eBay, or any other marketplace. The supplier’s audit protection comes from your certificate, not from the marketplace’s collection.
Reporting marketplace sales on your returns
Even when a marketplace collects tax on your behalf, most states still require registered sellers to report marketplace sales on their returns — typically as deductions from gross sales. Skipping this step can trigger audit flags because the state can see marketplace facilitator data separately.
There’s also the question of whether marketplace sales count toward your economic nexus threshold. Rules vary — some states include all sales in the threshold, others exclude marketplace sales. Because this varies materially by state and by year, contact us for a current review if you’re using multiple marketplaces plus drop shipping and unsure whether you’ve crossed thresholds anywhere.
The interaction of MF laws with FBA inventory nexus is particularly tricky. In California, for example, a marketplace seller with FBA inventory in California is generally engaged in business in the state, but if 100% of its California sales are facilitated by a CDTFA-registered marketplace facilitator such as Amazon, it is generally not required to hold a California seller’s permit or Certificate of Registration–Use Tax (CDTFA Pub. 109). The relief runs out the moment you sell anywhere else: if you also sell through your own store, or through a marketplace that is not registered with CDTFA, you remain responsible for those sales yourself and a permit may well be required. The position here depends on your own facts, so it is worth confirming with the state directly or talking to us about your situation.
Foreign Sellers Using US Drop Shippers
Foreign sellers running US drop-ship businesses face additional friction: no US Social Security number, sometimes no US EIN, and no US bank account. The good news: none of these are actual blockers. You can register, obtain resale certificates, and file US sales tax returns as a foreign entity.
Can a non-US LLC give a valid resale certificate?
Yes — but you need to be registered somewhere. The MTC Uniform Resale Certificate and the SST Certificate of Exemption both require you to reference a valid US state sales tax registration number. So the sequence is:
- Determine which US state(s) you have nexus in (economic or physical).
- Register in those states as a foreign entity.
- Use your state registration number(s) on your resale certificates.
A foreign LLC (typically a Delaware, Wyoming, or Florida LLC owned by non-US individuals) can register in any US state. You do not need to be a US citizen or resident to register for state sales tax.
Getting an EIN without an SSN/ITIN
You cannot register for state sales tax without a US federal Employer Identification Number (EIN). Foreign applicants obtain an EIN by completing Form SS-4 and either:
- Faxing the completed SS-4 to the IRS international fax number and receiving the EIN within a few business days (times vary — check current IRS guidance), or
- Calling the IRS International EIN line and getting an EIN issued on the call.
You do not need an SSN or ITIN to obtain an EIN for a foreign-owned entity. See our EIN-without-SSN guide for the current step-by-step.
What if you have no US bank account?
Payment methods for state sales tax remittance vary by state. Some states accept ACH debit from US bank accounts only; others accept credit card (with convenience fees); others accept wire transfers from foreign banks. For foreign sellers without a US bank account, the most common paths are:
- Open a US bank account with a fintech that serves non-residents (available for foreign-owned LLCs).
- Use a credit card for state tax payments where accepted.
- Have a US-based service handle payments on your behalf.
Because each state has different acceptable payment methods and different rules for foreign filers, the practical reality for most cross-border drop shippers is that a full-service compliance provider handles remittance end-to-end. See our foreign seller registration guide for a full walkthrough.
Step-by-Step: How to Structure Your Drop Ship Sales Tax Compliance
Here’s the compliance workflow every drop shipper should run once and then maintain quarterly.
Step 1: Map where your suppliers ship from
List every supplier and every warehouse they ship from. For each state, note whether the supplier holds any inventory earmarked for you (potential physical nexus) versus generic stock.
Step 2: Map where your customers are
Pull the last 12 months of retail sales data by ship-to state. Tag each state with (a) total revenue and (b) transaction count.
Step 3: Determine nexus in each state
For each state, apply three tests:
- Physical nexus: Do you or your supplier hold inventory in the state? Do you have employees, offices, or agents?
- Economic nexus: Have you crossed the state’s revenue or transaction threshold in the current or prior 12 months?
- Marketplace facilitator interaction: Are you selling into the state via a marketplace that already collects tax, and does that state’s law relieve you of registration?
Any “yes” to physical or economic triggers a registration obligation.
Step 4: Register and obtain resale certificates
For each state where you have nexus:
- Rather than give you a figure that may not apply to you, we would check this against the state’s current guidance for your specific setup — ask us and we will tell you exactly where you stand.
- Wait for your state sales tax number to issue (a few days to a few weeks).
- Complete the state-specific resale certificate (or the MTC/SST form if accepted) and provide it to each supplier that ships from or into that state.
- Confirm the supplier has updated your account to tax-exempt.
For the ten strict states (California, Florida, Hawaii, Illinois, Louisiana, Maryland, Massachusetts, Mississippi, Tennessee, Washington), pay extra attention: you need the state-specific certificate.
Step 5: Configure collection and remittance
Set up your ecommerce platform to collect sales tax at the correct rate for each ship-to state where you’re registered. Configure monthly, quarterly, or annual filing calendars per state. Track marketplace-facilitated sales separately from direct sales so you can report both correctly.
The Real Cost of DIY Drop Ship Compliance
This one varies by seller and by state, and it is the kind of detail we check for clients as part of the service — get in touch and we will confirm where you stand. Here’s the reality of what “compliance” actually involves once you’re operating at scale.
Software-only tools leave the hard parts to you
Automated sales-tax software calculates rates on your invoices and — in some cases — files returns. What they don’t do:
- Register you in each state (you do this yourself, state by state).
- Complete resale certificate paperwork for each supplier.
- Respond to state DOR notices when they arrive.
- Handle audits, correspondence, and appeals.
- Track marketplace-facilitator interactions with your direct sales.
- Manage foreign-seller registration friction (EIN, banking, payment).
You get a calculator. Everything else is on you.
The hidden 80 hours a year
For a drop shipper active in 15 states, the annual work looks roughly like:
- Registrations: 15 states × 1-3 hours each = 15-45 hours (one-time, but recurring for new states).
- Resale certificates: 10 states with paperwork to send to each supplier = 15-30 hours.
- Monthly filings: 15 states × 12 filings × 20 minutes each = 60 hours per year.
- Notice responses: 15 states × 2-4 notices per year × 45 minutes each = 25-45 hours per year.
- Quarterly nexus reviews: 4 hours × 4 = 16 hours per year.
- Rate/threshold changes and rule updates: 20 hours per year.
Total: roughly 80-160 hours per year of skilled compliance work. For a founder billing at even a modest hourly rate, this is $12,000-$25,000 in opportunity cost annually — plus real risk when a notice slips through and turns into a penalty assessment.

FAQ
Do I need to collect sales tax on drop shipped orders?
Yes, in every state where you have sales tax nexus (physical or economic). The fact that your supplier ships the product, not you, doesn’t change your obligation. If you have nexus in the ship-to state and the sale isn’t going through a marketplace facilitator that collects on your behalf, you collect tax at the ship-to state’s rate.
Who is responsible for sales tax in a drop shipping transaction?
The party with nexus in the ship-to state is responsible. When both you and your supplier have nexus, you collect from the customer and give your supplier a resale certificate for the wholesale leg. When only the supplier has nexus, the supplier collects from you unless you provide a valid resale certificate the ship-to state accepts.
Can I use my home-state resale certificate with an out-of-state supplier?
Sometimes. Most states accept the MTC Uniform Resale Certificate, which effectively lets you use one certificate across many states. But roughly ten states (California, Florida, Hawaii, Illinois, Louisiana, Maryland, Massachusetts, Mississippi, Tennessee, Washington) require their own state-issued certificate. In those states, you must register and use that state’s specific form.
Which states don’t accept out-of-state resale certificates?
The ten commonly cited states are California, Florida, Hawaii, Illinois, Louisiana, Maryland, Massachusetts, Mississippi, Tennessee, and Washington. Each has different mechanics — Florida issues the DR-13, California publishes the CDTFA-230 series, Washington issues a Reseller Permit, and so on. The workaround is to register in the state and obtain that state’s own certificate.
Does my drop shipper’s warehouse create sales tax nexus for me?
Potentially, yes. If your drop shipper holds inventory earmarked or consigned specifically for you, you may have physical presence nexus in that state — similar to the FBA inventory trap. If they ship from their generic wholesale stock, it’s less clear-cut. Because the specifics vary by state and arrangement, contact us for a specific analysis before assuming you’re safe.
Do wholesale drop-ship sales count toward economic nexus thresholds?
It varies. Some states measure the threshold against gross sales including exempt/wholesale sales; others measure only against retail sales. Because rules change and vary state-by-state, if your sales volumes are close to any state’s threshold, get a current review.
If Amazon collects the sales tax, do I still need a resale certificate for my supplier?
Yes. The marketplace’s collection handles the retail leg (marketplace → end customer). It does not handle the wholesale leg (supplier → you). Without a valid resale certificate, your supplier will charge you tax on the wholesale price, and you cannot recover it.
As a non-US seller, can I give a resale certificate to my US drop shipper?
Yes, but you must first register for sales tax in at least one US state as a foreign entity (typically starting with the state your supplier ships from or where your nexus first triggers). You’ll need a US EIN — obtainable without an SSN via Form SS-4 — and then a state registration. Once registered, the MTC or SST certificate (referencing your state number) works for foreign-entity retailers just like it does for US retailers.
What happens if my supplier charges me sales tax I can’t recover?
That tax becomes a straight cost of goods sold — it directly reduces your margin. You cannot pass supplier-paid sales tax through to your customer as your own sales tax collection (because it wasn’t collected on the retail leg). The two ways to prevent this are: (1) register in the state so your resale certificate is accepted, or (2) switch to a supplier whose location doesn’t create this problem for you.
Which state’s sales tax rate applies to a drop shipped order?
Almost always the ship-to state’s rate (destination sourcing). Even in origin-sourcing states, once the shipment crosses state lines, destination sourcing takes over. So look up the rate at the customer’s delivery address.
