Do you need a resale certificate to buy liquidation lots?

Written by the ZipToSale team · Published October 13, 2026 · Last updated October 13, 2026

Short answer: usually, yes. Most liquidation and wholesale sellers sell without sales tax, and to do that they need your resale certificate on file. Without one, a seller who collects sales tax in your state has to charge you tax, and many won't sell to you at all. Some lots don't require a certificate, and states with no sales tax don't use them.

What a resale certificate actually does

Sales tax is meant to be paid once, by the final customer. When you buy a pallet to resell, you're not the final customer; whoever buys from you is. A resale certificate is the document you give the seller to say so: "I'm buying these goods to resell them, so don't charge me sales tax; I'll collect it when I sell."

The seller keeps your certificate as evidence. If the state audits them and asks why they didn't charge tax on, for example, a $3,000 pallet, your certificate is the answer. That's why sellers care about the details: a certificate that's incomplete, for the wrong state, expired, or made out to a different business doesn't protect them, so they can reject it.

Who can get one

In almost every state with a sales tax, you need to be registered to collect sales tax before you can issue a resale certificate. The registration goes by different names: seller's permit, sales tax permit, certificate of authority, or license. It gives you a state registration number, and that number goes on your certificate.

If you sell to customers, whether online, at a store, at flea markets or through resale apps, you probably need that registration anyway. Most states let you apply online, often for a small fee or free, and many issue the number within days. Then the certificate itself is either:

  • a form you fill in with your registration number (most states), or
  • a document the state issues to you (Alabama, Florida, Louisiana, Mississippi, New Mexico, plus Maine's signed affidavit and Washington's reseller permit).

Which states use which

An EIN on its own usually isn't enough: most state forms ask for your state sales tax number.

When you can buy without one

  • The lot doesn't require one. Some sellers sell without asking for a certificate, and they may add sales tax to your invoice instead. On ZipToSale, filter for No resale certificate required.
  • The lot goes to a state with no sales tax. Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Alaska has local sales taxes in some areas, so a seller may still ask.
  • You're happy to pay the tax. You can buy a lot as a taxable purchase. But if you resell the goods, you've paid tax that your customer will pay again, and that's money you won't get back easily.

When you shouldn't use one

A resale certificate covers goods you'll resell. It doesn't cover things your business uses: store fixtures, packing supplies, a laptop out of an electronics lot that you keep for the office. If you buy tax-free and then use an item yourself, most states expect you to pay use tax on it directly. Misusing a certificate can carry penalties, so keep the distinction clean.

Which state's certificate?

For goods that are shipped, sales tax generally follows where the goods are delivered. So the certificate that matters is the one for the state the lot ships to, not the state the seller is in or where your business is incorporated. If you collect the lot yourself from the seller's warehouse, it's the seller's state.

That catches out buyers who are registered at home and buy a lot shipped to a warehouse in another state. Many states accept a multistate certificate completed with your home-state number; some don't. Reselling across state lines

Common mistakes that get certificates rejected

  1. The business name doesn't match. For example, the certificate names "Smith Holdings LLC" but your account and invoices say "Bargain Barn". Put your legal name and DBA on the certificate exactly as registered.
  2. Wrong state. A Texas certificate for a lot shipped to Oklahoma.
  3. Expired. Florida's annual certificate expires every December 31. Alabama licenses renew yearly. Louisiana certificates print an expiry date. More on these three
  4. Missing number or signature. A blank registration number, or an unsigned form.
  5. Unreadable upload. A cropped phone photo where the number or date can't be read.

How it works on ZipToSale

ZipToSale was built around this paperwork, so you deal with it once:

  1. Add your certificate under Buying › Settings › Reseller certificates. Upload it if your state issues one, or fill in your state's form online and we produce the PDF. Add one for each state you buy into.
  2. We check it for the state, number, expiry and business name, usually within minutes, and tell you what to fix if something's off.
  3. When you order, we share the right state's certificate with that seller only, and the seller reviews it on the order page. No emailing PDFs, no re-sending it to every new seller.

Every listing says whether a certificate is required before you add it to your cart.

Quick checklist

  • Registered for sales tax in at least one state, with your registration number to hand
  • Certificate for each state your lots ship to (or the seller's state for pickups)
  • Legal name and DBA match your registration
  • Current, not expired
  • Used only for goods you'll resell
