The seller's permit question: what to do when a Show asks for one before you can set up

Somewhere in the paperwork for a fall or holiday Event — the vendor agreement, the acceptance email, a line on the application itself — a fair number of vendors run into a request they weren't expecting: a copy of your seller's permit, or proof that you're registered to collect sales tax. If you've only ever sold at a handful of local Markets, it's easy to have never thought about this at all. If you're now applying somewhere new, or an Event you've worked before has suddenly started asking, it's worth understanding what's actually being requested before a deadline forces the question.

This is general information, not personalized tax or legal advice — there's a fuller note at the end. But knowing the shape of it will save you from either ignoring a real requirement or panicking over paperwork you don't actually need.

Three different things that get lumped together

A lot of the confusion here comes from three separate pieces of paperwork getting talked about as if they're one thing.

A business license is usually a local or municipal requirement — permission to operate a business within a city or county, sometimes tied to a fee, sometimes not. It has nothing to do with sales tax on its own; it's closer to the same category as a permit to run any kind of business in that jurisdiction.

A seller's permit — also called a sales tax permit, a certificate of authority, or a retailer certificate depending on the state — is what actually authorizes you to collect sales tax from customers and remit it to the state. This is the one a Show is usually asking for, and it's issued by a state department of revenue (or equivalent agency), not by any federal office. There's no such thing as a national seller's permit; if you sell in more than one state, some states expect you to register separately in each one where you have a taxable presence.

A resale certificate (sometimes called an exemption certificate) is the one vendors most often mix up with a seller's permit — and it points the opposite direction. It's what you hand to your own suppliers so you don't pay sales tax on materials and inventory you're buying to resell, since the tax gets collected once, from the end customer, not twice. A Show organizer asking for your seller's permit isn't asking for this; they want proof you're set up to collect and remit tax on what you sell at their Event, not evidence of what you didn't pay on your raw materials.

Why a one-off Event can still trigger it

The instinct is to assume this only matters for vendors who sell constantly, in one home state, at a scale that feels like a "real" business. That's not how most states actually draw the line. A number of states expect registration the first time you make a taxable sale in that state at all, with no minimum sales count before it applies — a single weekend Festival can be enough to trigger the requirement. Others use a small threshold, like registering once you cross a handful of sales in a rolling period, rather than a per-event count. A few states have carved out a genuine small-seller exemption for low annual sales, but the dollar threshold and the fine print vary by state and change over time, so treat any specific number you read — including here — as a starting point to verify, not a rule to rely on.

The practical result is that "I only do this one Event a year" or "I'm just selling out of state for a weekend" isn't a reliable reason to assume no permit is needed. Some states even have a separate, simpler temporary or special-event permit specifically for vendors passing through for a single Show, rather than making a traveling vendor go through the same registration as a year-round retailer based there.

What to actually check before the Event

None of this needs to be a mystery by the time a booth fee is due. A few things are worth confirming ahead of the weekend, not the morning of load-in:

• What the Event is actually asking for. Read the request on the application or in the acceptance packet closely — some organizers want a copy of an existing permit, some want the number written on a form, and a few states require the organizer itself to collect a list of vendor permit numbers for their own compliance. Knowing which one saves a back-and-forth email close to the deadline.
• Whether you're already registered in your home state. If you regularly sell there, you may already have a seller's permit and just haven't been asked to show it before. Check whatever paperwork you filed when you started selling, or your state department of revenue's vendor lookup, before assuming you need to start from scratch.
• Whether the Event is in a state where you're not already registered. This is the case most likely to catch a vendor off guard — a Festival a few states away from home, in a state with its own registration rules, on its own timeline. Registering can take anywhere from same-day online to a couple of weeks depending on the state, so this is worth starting as soon as an Event confirms, not the week before.
• Whether that state has a temporary or special-event version. Some states offer a lighter-weight registration specifically for vendors who are only selling there for a short run of days, rather than the standard ongoing retailer registration — worth asking about if the standard process looks like more than a weekend Event warrants.

A state department of revenue's own website is the reliable source for all of this — most have a specific page for craft, Market, or special-event vendors, and registration itself is usually free or low-cost. That's also the place to confirm current thresholds and exemptions rather than relying on a number that might be out of date by the time you read it.

If a permit turns out to be genuinely unnecessary

A handful of states — Alaska, Delaware, Montana, New Hampshire, and Oregon — don't have a statewide sales tax at all, so a seller's permit request for an Event held entirely in one of those states may not apply in the way it would elsewhere (Alaska is the exception among the five, since some of its local municipalities levy their own sales tax even without a state one). If an Event is asking for a permit and you genuinely believe it doesn't apply to your situation, that's worth confirming with the state directly — or with a tax professional — rather than assuming based on where you sell most of the time.

The takeaway

A seller's permit, a resale certificate, and a general business license are three different things that solve three different problems, and it's easy to see a request for one and reach for the wrong paperwork. Most states expect a vendor to be registered to collect sales tax before they sell there at all — sometimes triggered by a single Event, not a sales threshold — and the fastest way to avoid a scramble is checking the requirement for a new state as soon as an acceptance comes in, not the week of the Show.

This article shares general information, not personalized tax or legal advice. Sales tax registration rules, thresholds, and exemptions are set by each state, vary widely, and change over time — for your specific situation, check your state department of revenue's current guidance or talk to a CPA or tax professional familiar with multi-state vendor sales.

Keeping track of which Events ask for a seller's permit — and whether you've already sent one — is one more thing that's easy to lose between an acceptance email and the weekend itself. The Tracker's notes field on each application is a simple place to keep that detail alongside the deadline and everything else for that Show.
