Who is liable for tax if I never touch the goods I sell?
Possibly you, possibly your supplier, possibly the final customer, and the answer changes with the rules of each country in the chain rather than with who physically handled anything. In a drop-ship arrangement nobody holds the stock and every party is a potential taxpayer. What decides it is who imports, where title passes, and who is treated as making the supply to the final customer. Those three facts sit in your contracts and your delivery terms, not in a warehouse, which is why the analysis starts with the paperwork of the chain rather than with the logistics.
Where does my sale take place if the supplier ships direct?
Where a sale is treated as taking place depends on rules that do not all point the same way: some follow the passing of title, others follow the physical movement of the goods. In a drop-ship chain those two diverge by design, so the same shipment can be placed in different countries by different systems. That is not a drafting error to be resolved by choosing one of them; it is the exposure itself. Map each leg separately, supplier to you and you to customer, and test each against the rules of the countries that leg touches.
Do I need to register where my supplier's warehouse is?
Not necessarily, and not automatically either. The presence of stock in a country is one fact among several, and it matters mainly through its consequences: who imports the goods, where title to them passes, and who is treated as making the supply onward. A seller with no presence of its own can still pick up an obligation where the goods move, and a seller whose supplier ships from a country can sometimes have none there. Work it out per country and per flow rather than from a general rule about warehouses, because the general rules differ between systems.
Who is the importer in a drop shipping chain?
Whoever is named as such on the entry, and where three parties are involved that is a decision somebody makes rather than a fact that emerges. It carries real consequences: the importer accounts for the tax at the border and is normally the party in a position to recover it. Chains go wrong when the choice is made by a freight forwarder for operational convenience and nobody in the tax function sees it. Settle it in the contracts with both your supplier and your customer, and make sure the delivery terms say the same thing as the entries.
What is drop shipment relief and what do I need to claim it?
Some systems have provisions that keep a drop-shipment from producing an unnecessary charge or an unnecessary registration, typically by deeming who makes the supply or by relieving one leg of the chain. They are not automatic. Each comes with conditions, and with documentation that has to exist at the time: certificates, declarations, or evidence from another party in the chain. That is the part that fails in practice. The relief is identified correctly and then claimed without the paper, or claimed with paper collected long after the fact. Decide which relief you are relying on before you ship, and collect its evidence as part of the order flow.
Does it matter where title passes if delivery is the same?
Yes, because some rules follow title and others follow delivery, and it is the divergence between them that creates the exposure rather than either fact on its own. Two arrangements with identical logistics can produce different registration outcomes purely because title passes in a different place. The corollary is that delivery terms are tax documents. If your contracts are silent on where title passes, or say different things upstream and downstream, you do not have a position to defend. You have whichever position each authority prefers to read into the silence.
Which countries have a tax treaty with the United States?
Around sixty, including Canada, the United Kingdom, India, Australia and most of western Europe — but the list matters less than the terms, because each treaty caps rates and allocates income differently. Two countries with treaties can produce opposite answers on the same pension or the same royalty. What decides your position is the specific article covering your income type. See our country guides.
Is double taxation legal?
Yes. Nothing prevents two countries from taxing the same income under their own domestic law — each is exercising its own jurisdiction. What treaties and credit systems do is relieve the outcome rather than prohibit the charge, and relief is generally something you must claim on a return or a form, not something applied automatically. Miss the claim and the double charge stands. Double taxation explains the mechanism.
