Sales tax is charged once, at the end of the chain, to the person who actually consumes the product. A shop buying from you is not consuming it; they are reselling it. So a wholesale sale is normally exempt, and the shop charges tax to the customer instead.
The catch is that the exemption is not automatic. It depends on the buyer giving you a document — a resale certificate — and on you keeping that document somewhere you can produce it years later. Without it, the tax authority's position is that you should have charged tax, and the bill lands on you rather than on the shop.
None of this is legal advice, and rules differ by jurisdiction. What follows is the operational shape of it, which is consistent almost everywhere.
What a resale certificate actually is
It is a short form in which a business states that it is buying goods for resale rather than for its own use, gives its tax registration number, and accepts responsibility for the tax when it sells them on.
The name varies — resale certificate, reseller permit, exemption certificate, and outside the United States an equivalent registration number rather than a form. The function is identical: it moves the obligation to charge tax from you to them.
You do not issue it and you do not verify it in any deep sense. The buyer provides it, you check it is complete and plausible, you keep it, and you stop charging tax on that account's orders.
Collect it before the first order ships
Make the certificate part of account setup, not an afterthought. The right moment to ask is when the buyer fills in your order form, which is why it belongs as a field on the wholesale order form.
What a complete certificate needs, in practice:
- The buyer's legal business name and address, matching the name on the order
- Their tax registration or permit number
- A description of what they are buying that covers your products
- A signature and a date
- Where required, your business named as the seller
If the certificate arrives incomplete, send it back. An incomplete certificate is not protection, and the moment it is challenged you will discover that the missing signature mattered.
If the buyer does not have one, charge tax. Some very small shops, market traders and new businesses genuinely do not have a registration yet, and charging them is correct rather than unfriendly. Tell them they can send the certificate when they have it and you will stop charging from the next order.
Where you owe tax at all: the nexus question
The second layer is whether you have an obligation in the buyer's jurisdiction in the first place.
Tax authorities generally treat you as obliged to collect when you have a connection to their territory: a physical presence such as an office, staff or stock held in a warehouse, or enough sales into it to cross a threshold. Wholesale changes this picture in two ways that surprise DTC brands.
Holding stock at a third-party warehouse in another state or region can create an obligation there, even if you have never visited. That is worth checking before you sign a warehouse contract, alongside the operational questions in choosing a 3PL for wholesale orders.
And exempt sales still count toward thresholds in many places. Selling a large volume of untaxed wholesale into a territory can trigger a registration requirement even though you owe no tax on any of those sales. Registering and filing returns showing exempt sales is the normal outcome.
This is the part worth paying an accountant for, once, when wholesale becomes a real share of revenue.
What the invoice should look like
An exempt invoice is not an invoice with the tax line deleted. It should show, explicitly, that tax was not charged and why.
| Line | What it shows |
|---|---|
| Subtotal | Goods at wholesale price |
| Freight | Charged or included |
| Sales tax | Zero, marked as resale exemption |
| Total | What they owe |
Add the buyer's certificate or registration number somewhere on the document. It takes a field in your invoice template and it answers the question before anyone asks it. The rest of what belongs on the document is in the wholesale invoice.
Note the freight line separately from the goods. In some jurisdictions shipping is taxable and in others it is not, and burying it in the goods total removes your ability to treat it correctly later.
Keeping the certificates where you can find them
Certificates have to be produced on demand, sometimes years after the sale, by which time the buyer may have closed the shop and the email thread will be unfindable.
A workable system for a small brand: one folder, one file per account, named with the account name and the date received. A column in your account list showing certificate on file and its expiry, if it has one. A note in the calendar for renewals, because some jurisdictions issue certificates that expire and others accept a blanket certificate covering all future orders from that buyer.
Review the folder once a year against your customer list. Any account with orders and no certificate is an exposure, and the fix is a two-line email that takes a minute now and is very awkward during an audit.
Where this connects to the rest of your books is in wholesale bookkeeping, which is where exempt and taxable sales get separated for filing.
Selling in both channels without confusing the two
Running DTC and wholesale from the same business means both kinds of sale exist side by side, and your systems need to tell them apart.
In a store admin, that means tagging wholesale customers as tax exempt so the exemption applies automatically at order creation rather than being edited in by hand. Manual edits get forgotten on the one order that gets audited.
It also means your reports need to split the two. A monthly total that mixes taxed consumer sales with exempt wholesale sales cannot be reconciled against a tax return, and reconciling it afterwards is a miserable afternoon. Separate the channels at the point of sale and the filing becomes arithmetic rather than archaeology. The wider version of that separation is in wholesale accounting.
Buying as well as selling
The same mechanism works in your favour on the purchasing side. Materials and components that become part of a product you resell can often be bought without tax, using your own resale certificate given to your supplier.
Packaging that ships with the product usually qualifies. Equipment, office supplies and anything you consume in running the business usually does not. Suppliers will ask for your certificate on file before applying it, so send it once to each of your main suppliers and keep a copy.
It is not a large saving on any one purchase and it is meaningful across a year of component buying, particularly for a brand ordering glass, tins and printed cartons in quantity.
If you are earlier than all of this — no accounts yet, no certificates to file — the useful work is finding the shops. Paste your product link into WholesalePilot and look at the preview of retailers that stock similar products; the paperwork follows the orders, not the other way round.
Questions brands ask about wholesale sales tax
Do I charge sales tax on wholesale orders? Not when the buyer provides a valid resale certificate and you have an exemption available in that jurisdiction. Otherwise yes.
What if a buyer refuses to send a certificate? Charge tax. The obligation falls on you if you cannot evidence the exemption, and no account is worth carrying that.
Does a certificate cover future orders? Often, as a blanket certificate, but not everywhere and not forever. Check whether it expires and diarise the renewal.
What about international wholesale orders? Export sales are typically outside the domestic tax system entirely, but customs, duties and the buyer's own import obligations replace it. Agree in writing who pays them before shipping.
Should I use an accountant for this? For the registration and threshold questions, once wholesale is a real revenue line, yes. The certificate handling itself is admin you can run yourself.
