Dropshipping Tax Treatment: Sales Tax on Resale, Income Reporting, and When You Need a Resale Certificate

A dropshipper is legally the retailer in every transaction, responsible for collecting sales tax from the end customer, even though the product ships directly from a supplier or manufacturer the dropshipper never physically touches. That single fact drives most of the tax questions specific to this model: the dropshipper needs a resale certificate to buy from its supplier tax-free (since the supplier’s sale to the dropshipper is a wholesale, not retail, transaction), the dropshipper’s own income is measured on revenue minus cost of goods, not gross sales collected, and nexus rules apply to the dropshipper based on where its customers are, not where its supplier’s warehouse sits. On top of the normal e-commerce tax questions, international dropshipping now carries a materially bigger cost than it did two years ago, because the $800 de minimis import exemption that let low-value packages enter the US duty-free was suspended for nearly all shipments in August 2025 and made permanent in 2026.

Who collects sales tax in a dropshipping transaction?

The dropshipper does, on its sale to the end customer, in every state where the dropshipper has nexus, using the same nexus rules (economic and physical) that apply to any online retailer. For current guidance, see Streamlined Sales Tax governing board. This is true regardless of where the supplier ships the product from or whether the supplier itself has nexus in the customer’s state.

• The dropshipper’s sale to the customer is a retail sale. Sales tax is calculated on the price the customer pays the dropshipper, not on the (lower) wholesale price the dropshipper pays the supplier. A dropshipper selling a product for $60 that it bought from its supplier for $35 collects sales tax on the full $60, not on the $25 markup.
• Nexus is determined by the dropshipper’s own activity, using the standard economic nexus thresholds (commonly $100,000 in sales, with some states layering on a 200-transaction test, and higher thresholds in states like California and Texas). This works exactly like nexus for any other online seller, covered in full in E-commerce sales tax nexus.
• The supplier’s location generally does not create nexus for the dropshipper. Nexus is about the dropshipper’s own economic activity and physical presence, not the supplier’s. A dropshipper working with a supplier warehouse in a state where the dropshipper otherwise has no sales, employees, or property generally does not acquire nexus in that state purely because the supplier ships from there. This is a meaningful contrast with the FBA model, where the seller’s own inventory sitting in a state does create nexus; a pure dropshipper never owns inventory that sits anywhere, so that particular trigger does not apply.
• A handful of states have specific rules about drop-shipment transactions themselves, mostly addressing which party (the dropshipper or the supplier) is responsible for tax when the supplier ships directly to the end customer on the dropshipper’s behalf and documentation is incomplete. These rules typically resolve in the dropshipper’s favor as the retailer of record when a proper resale certificate is on file, but they can shift liability onto the supplier to collect tax as if it were a retail sale if the dropshipper cannot produce a valid certificate.

What’s a resale certificate, and when do I need one?

A resale certificate is a document a buyer gives to a supplier certifying that the goods being purchased are for resale, not for the buyer’s own use, which allows the supplier to sell to the buyer without charging sales tax on that wholesale transaction. Without one, the supplier is generally required to charge the dropshipper sales tax on the wholesale purchase, which the dropshipper then cannot recover, even though it goes on to collect sales tax again from its own customer on the retail sale, effectively taxing the same product twice.

• The mechanics: the dropshipper registers for a sales tax permit in the states where it has nexus, then uses that registration to issue a resale certificate (sometimes a state-specific form, sometimes the Streamlined Sales Tax exemption certificate accepted by member states, sometimes the Uniform Sales & Use Tax Resale Certificate accepted more broadly by many suppliers) to its supplier, certifying the goods are purchased for resale.
• A resale certificate is only valid where the dropshipper actually has nexus and a permit. A dropshipper cannot issue a valid resale certificate for a state where it has no sales tax registration, because a resale certificate presumes the holder is itself a registered retailer collecting tax on the eventual retail sale. This creates a real gap for a dropshipper with nexus in only a handful of states: purchases destined for customers in states where the dropshipper is not registered may not qualify for the resale exemption from the supplier at all, depending on the supplier’s own policies and the state’s rule.
• Suppliers can and do refuse to honor a resale certificate they consider incomplete or suspicious, and a dropshipper working with multiple suppliers should expect to manage a resale certificate on file with each one, updated as new state registrations are added.
• This is a compliance cost that grows with the number of states a dropshipper is registered in, since each new state registration is both an opportunity (a valid resale certificate there) and an obligation (a return to file there, even in periods with no tax due).

How should dropshipping income actually be reported?

Revenue minus cost of goods sold, not gross sales collected from the customer. This sounds obvious, but dropshippers processing payments through Stripe, PayPal, or a marketplace often receive a 1099-K reporting the full gross amount collected from customers, and the temptation to report that 1099-K figure as taxable income directly, without subtracting what was paid to the supplier, materially overstates profit.

• Gross revenue is the full amount collected from the customer (product price plus any shipping charged), matching what appears on a 1099-K from the payment processor.
• Cost of goods sold is the amount paid to the supplier for the specific units sold, including whatever the supplier charges for its own shipping to the end customer, since that is part of the cost of fulfilling the sale, not a separate operating expense.
• Net profit, the actual taxable income before other business expenses (advertising, software, platform fees), is revenue minus that cost of goods sold. A dropshipper who reports the full 1099-K gross figure as income without backing out supplier cost is overpaying tax on money that never became profit; one who reports far less than the 1099-K figure without documentation risks an IRS mismatch notice, since the 1099-K total is reported to the IRS independently of the seller’s return.
• The bookkeeping challenge specific to dropshipping is tying each sale to its specific supplier cost, since the dropshipper never has physical inventory to count and reconcile against; the cost basis exists only in supplier invoices and order-level records, which makes clean, order-by-order recordkeeping more important here than in a model where a periodic physical inventory count can catch errors.

Does dropshipping create nexus differently than inventory?

Yes, in one important respect: a pure dropshipper never triggers the inventory-based physical nexus that applies to a seller who holds stock (whether in their own warehouse or in a fulfillment network like FBA), because a pure dropshipper never owns inventory that physically sits anywhere on its behalf. Its nexus exposure is economic-nexus-only, driven by sales volume into each state, using the same thresholds covered in E-commerce sales tax nexus.

• This is the practical opposite of the FBA model covered in Amazon FBA tax issues, where inventory scattered across a fulfillment network creates physical nexus regardless of sales volume. A dropshipper trades that specific inventory-nexus risk for a different set of risks: resale certificate management, thinner per-unit margins, and (for international suppliers) the customs exposure covered next.
• A dropshipper working with a supplier that also has its own retail operations or its own nexus footprint should not assume the supplier’s registrations do anything for the dropshipper. Each party’s nexus and registration obligations are separate and independent.

What changed with the international de minimis exemption?

Executive Order 14324 suspended the $800 de minimis duty-free exemption for essentially all non-postal shipments into the United States, effective August 29, 2025, applying to every country of origin, not just the countries previously targeted by earlier, narrower suspensions. In mid-2026, US Customs and Border Protection made that suspension a permanent federal regulation rather than a standing executive order, and separate legislation enacted in 2025 sets a statutory end date for the de minimis exemption entirely, effective July 2027, regardless of any future executive action.

• What this means practically: a dropshipper sourcing product from an overseas supplier (a common model built around suppliers in China and elsewhere shipping directly to US customers) can no longer rely on low-value packages entering duty-free. Nearly every package now requires a formal or informal customs entry and is subject to applicable duties and tariffs, based on the product’s classification and country of origin, regardless of how low its declared value is.
• The postal network exception is narrow and does not apply to most commercial dropshipping volume. Shipments moving through the international postal network retain different treatment, but the bulk of commercial dropshipping freight (moving by air or ocean express carriers, not through postal channels) does not qualify for that narrower exception.
• The cost impact falls on margin, not on a separate line item customers necessarily see broken out. Depending on how a dropshipper’s supplier and fulfillment arrangement handles the customs entry and duty payment, the added cost either gets built into what the supplier charges the dropshipper, or the dropshipper (or, in some arrangements, the customer directly) becomes the importer of record responsible for the duty. Any dropshipper still sourcing internationally needs to confirm, supplier by supplier, who is legally the importer of record and who is absorbing the duty cost, because that allocation is no longer automatic or free the way it was when de minimis applied.
• Margins built on the assumption of duty-free entry need to be re-modeled. A dropshipping business whose unit economics assumed no import duty on a sub-$800 item should re-run those numbers now that the exemption is gone across essentially the entire market, not just for shipments from a specific country.

What entity structure applies to a dropshipping business?

Dropshipping businesses tend to start as sole proprietorships (or single-member LLCs disregarded for tax purposes) because startup capital requirements are low, and the entity question becomes worth revisiting once profit reaches a level where self-employment tax savings from an S-corp election are meaningful, generally somewhere in the range of $40,000 to $60,000 in net profit, depending on the specific numbers, and after accounting for the added cost of running payroll and a separate corporate return.

• A single-member LLC taxed as a sole proprietorship (or a sole proprietorship with no LLC at all) is simple to operate but exposes 100% of net profit to self-employment tax (15.3% up to the Social Security wage base, 2.9% above it) in addition to income tax, with no ability to split income between wages and distributions.
• An S-corp election lets the owner take a reasonable salary (subject to payroll tax) and take remaining profit as a distribution not subject to self-employment tax, which is where the savings come from, but it also introduces payroll processing, a separate Form 1120-S return, and state-level registration and franchise tax obligations in some states, all of which have a real cost that needs to be weighed against the projected savings before making the election.
• Multi-state sales tax registrations (covered above) are a separate question from entity structure and apply regardless of whether the business operates as a sole proprietorship, LLC, or S-corp; the entity choice affects income tax and self-employment tax, not sales tax nexus or registration obligations.

What should I do next?

Confirm you have a valid resale certificate on file with every supplier for every state where you are registered, and identify any states where you have nexus but no resale certificate in place with your suppliers. Review your bookkeeping to confirm net income is being calculated as revenue minus actual supplier cost, not as the gross 1099-K figure. If you source internationally, get a clear answer from each supplier on who is the importer of record and who is absorbing customs duty now that the de minimis exemption is gone, and re-check your unit margins against that added cost.
