Resale Certificates for Thrift & Flea Market Sourcing: What Works Where

Here's the direct answer: generally yes. A resale certificate can save you the sales tax on inventory you source at thrift stores, flea markets and estate sales, if you're registered for sales tax and the items are for resale. California puts it simply: "Purchasers who are engaged in the business of selling tangible personal property may issue resale certificates when purchasing items they will sell in the regular course of their business operations" (CDTFA).

Three things make sourcing different from buying from a wholesaler. Some of the places resellers buy, like a qualifying garage sale in Texas or California, don't charge sales tax in the first place, so there's nothing to exempt. A certificate only works if the seller accepts it, and states tell sellers to be careful about which certificates they accept. And if you pay the tax anyway, some states let you get it back on your return. This guide covers each, step by step.

Key Takeaways

• A resale certificate covers only items you'll resell, and for sellers based in Texas or California it rests on a sales tax permit. Texas says "a copy of the customer's permit is not a substitute for a resale certificate" (Texas Comptroller).
• Qualifying garage sales by individuals often don't charge tax in Texas and California, so a certificate does nothing there. New York's garage-sale exemption is narrower, and estate sales run by a third party are taxed in New York.
• A certificate works only if the seller accepts it. Texas exempts the purchase "if the seller accepts" a properly completed certificate (Texas Comptroller), and for its multistate form the Multistate Tax Commission says "the Seller will determine whether it will accept the certificate from the Buyer" (MTC).
• If a Texas or California vendor charges you that state's tax on items you resell, Texas permit holders can take a credit or request a refund, and California filers can deduct tax-paid purchases resold before use.
• Using a certificate for personal items can be costly: California can charge a penalty of 10% of the tax or $500, whichever is greater, for each purchase made for personal gain or to evade tax (CDTFA).

Before You Begin: What You Need

A resale certificate isn't a document the state hands you. It's a form you fill out and give to the seller, and it rests on your registration.

• A sales tax permit. In Texas, a taxable item bought for resale "is exempt from sales or use tax if the seller accepts a properly completed Form 01-339, Texas Sales and Use Tax Resale Certificate (PDF), instead of collecting the sales tax due," and the permit itself doesn't stand in for the form (Texas Comptroller). California describes the seller's permit as a license that lets you "issue resale certificates to suppliers" (CDTFA). If you're not sure you need a permit at all, our guide to whether you need a reseller permit to sell online covers that first.
• The right form. Each state has its own, and some sellers accept multistate forms. Our resale certificates explainer lists the main state forms.
• Items you'll actually resell. The certificate covers inventory, not the coffee mug you keep for yourself.

Which Sourcing Spots Charge Sales Tax at All?

A certificate only matters where the seller would otherwise charge you tax. Sourcing spots differ.

Garage sales vary by state. In Texas, an individual who qualifies for the occasional-sale exemption doesn't "need a sales tax permit, and you do not collect tax on those sales" (Texas Comptroller). In California, someone holding a garage sale is "generally not required to hold a seller's permit unless you have more than two garage sales in a 12-month period or are required to hold a seller's permit for being engaged in the business of selling" (CDTFA). New York is stricter. Its exemption for sales at your home requires, among other things, that "you make sales for three days or less in a calendar year" and "you do not expect your sales to exceed $600 in a calendar year" (NY DTF).

One Texas wrinkle. The Texas occasional-sale rule also says that a person who holds a Texas permit "and who makes a purchase in a transaction on which the seller is not required to collect tax under subsection (b) of this section, must accrue and remit tax to the comptroller on the transaction" (34 Tex. Admin. Code § 3.316(i)). The rule doesn't say how that applies to items bought for resale. If you hold a Texas permit and source at garage sales, ask the Comptroller how to handle those purchases.

Selling at flea markets yourself is a separate question, covered in our thrift and vintage reseller guide.

How to Use a Resale Certificate When Sourcing

Step 1: Confirm you're registered where you're buying

If you're sourcing in the state where you hold your permit, use that state's form. If you're buying in another state, see the section on sourcing out of state below before you hand anything over.

Check: you have your permit number to hand. In Texas, the permit alone isn't a substitute for the form.

Step 2: Fill out the certificate before you shop

Complete your state's form, or a multistate form the store accepts, with your business details. Some stores ask for specifics. ShopGoodwill.com, the online shopping site operated under Goodwill of Orange County's copyright, accepts tax exemption "for retail resellers," but its instructions ask for your "Business/Organization Name and Address (Individual name is not accepted)" and a certificate "dated in the current year" (ShopGoodwill). We found no published policy for buying in Goodwill's or other thrift chains' stores, so ask at the store.

Check: the form is signed, dated and filled in completely.

Step 3: Give it at or before the purchase

Timing matters to the seller. California says that "when a seller accepts a valid resale certificate in good faith and in a timely manner, the seller does not owe tax on that sale" (CDTFA). Ask at the register before you're rung up, not after.

Check: your receipt shows no sales tax on the items.

Step 4: Keep inventory and personal items apart

Texas tells buyers that when some items are for resale and others aren't, "you must clearly indicate to the vendor which items will be resold and on which the vendor should not collect tax" (Texas Comptroller). A separate transaction for personal items makes that easy. Texas is also direct about personal use: "If you use the merchandise that you purchased by issuing a resale certificate, then you owe tax on the merchandise" (Texas Comptroller).

Check: nothing on the tax-free receipt is going to stay in your closet.

Step 5: Keep copies and receipts

Keep a copy of each certificate you hand over, along with the receipt. The Streamlined Sales Tax form, for example, tells buyers to "send the completed form to the seller and keep a copy for your records" (SSTGB). Stores keep theirs too: Texas tells sellers to keep resale certificates in their records "for four years" (Texas Comptroller).

What If the Store Won't Take Your Certificate?

Stores can say no. For its uniform certificate, the MTC says the seller decides whether to accept it, and there are reasons stores hesitate. Texas tells sellers they "should not accept the certificate if you know or have reason to believe the property is being purchased for other than resale" (Texas Comptroller). Connecticut tells retailers "the property purchased must be similar to or of the same general character as what you could reasonably assume the issuer would sell" (Connecticut DRS). A thrift store sells mostly to people buying for themselves, so a cashier may not be able to tell inventory from a personal purchase.

If you pay a state's tax anyway, you may be able to recover it on that state's return:

• Texas permit holders. In its answer to Texas sellers who buy inventory to resell through a marketplace, the Comptroller says: "If the vendor does not honor the certificate and you are charged sales tax on items you purchase for resale, you can take a credit on your next sales tax return or request a refund from our office" (Texas Comptroller).
• California return filers. "If a purchaser paid sales tax to its supplier for items it purchased for business or personal use, but resold the items before any taxable use, the purchaser can take a deduction on their tax return when they report the sale," under "Cost of Tax-Paid Purchases Resold Prior to Use" (CDTFA).

These routes recover Texas or California tax on that state's own return. Other states have their own rules, so check with the state that charged the tax before counting on a credit.

Can You Use Your Certificate When Sourcing in Another State?

Sometimes. If you're sourcing on a road trip, the answer depends on the state you're buying in, not the state you're registered in. Our resale certificates explainer covers the general rules for buyers who aren't registered in a state; here's what matters at the register.

• The MTC uniform certificate. The Multistate Tax Commission says "36 States have indicated" its Uniform Sales & Use Tax Resale Certificate "can be used as a resale certificate" (MTC). It also warns that it "cannot guarantee that any state will accept this certificate," and that "some states require that the reseller (Buyer) be registered to collect sales tax in the state where the reseller makes its purchase" (MTC). Its state notes say Illinois requires an Illinois registration or resale number ("no other state's registration number is acceptable") and Maryland won't honor certificates without a Maryland number.
• The Streamlined Sales Tax certificate. For its member states, a buyer who isn't registered in the state can "provide your sales tax ID number issued by any state," but "not all states allow all exemptions listed on this form" (SSTGB).
• Texas. Texas sellers may accept a resale certificate from a retailer located outside Texas, and may accept the MTC form, but "the Streamlined Sales and Use Tax Agreement Certificate of Exemption may not be accepted as a resale certificate" (34 Tex. Admin. Code § 3.285).
• California. A buyer who isn't required to hold a California permit "because the purchaser makes no sales in this state" must explain on the certificate why, in place of a California permit number (CDTFA Regulation 1668).

If your out-of-state certificate is refused, you pay the tax like any shopper.

Common Mistakes and How to Avoid Them

• Using the certificate for personal items. In Texas, illegal use of a resale certificate is a criminal offense, from a Class C misdemeanor when less than $20 of tax is evaded up to a second-degree felony at $20,000 or more (Texas Comptroller). In California, the penalty is "10 percent of the tax or $500, whichever is greater, for each purchase made for personal gain or to evade payment of tax" (CDTFA). Florida calls resale fraud "a third-degree felony subject to a 200% penalty" (Florida DOR).
• Counting on the store to accept it. No source we found requires a seller to accept one. Know your recovery route, a credit or deduction where the state that charged the tax allows one.
• Showing your permit instead of a certificate. In Texas, a permit or a copy of it "is not a substitute for a resale certificate."
• Assuming one certificate works everywhere. Check the state you're buying in, especially Illinois, Maryland and Texas.

Frequently Asked Questions

Can I use a resale certificate at a thrift store?

Generally yes, if you hold a sales tax permit and the items are for resale, but it works only if the store accepts it. ShopGoodwill.com publishes its own requirements for online purchases; we found no published policy for buying in Goodwill stores. If a Texas or California store charges you tax anyway, Texas permit holders can take a credit or request a refund, and California filers can deduct tax-paid purchases resold before use.

Do I need a resale certificate at a garage sale?

Usually not. In Texas and California, individuals who qualify for an occasional-sale exemption don't collect sales tax, so there's nothing to exempt. New York's exemption for sales at home is narrower, limited to three days or less a year and expected sales of $600 or less, and estate sales run by a third party are taxed there. If you hold a Texas permit, Texas's occasional-sale rule says a permit holder buying where the seller needn't collect must accrue and remit tax; it doesn't say how that applies to items bought for resale, so ask the Comptroller.

Do flea market vendors have to accept resale certificates?

No source we found requires them to. For its uniform certificate, the Multistate Tax Commission says the seller decides whether to accept it. Many vendors do charge tax: Texas requires sellers at markets and shows who sell taxable items to hold a permit, and California generally requires sellers of new or used merchandise to hold a seller's permit.

Can I use my resale certificate when sourcing in another state?

Sometimes. The Multistate Tax Commission says 36 states have indicated its uniform certificate can be used as a resale certificate, but some, such as Illinois and Maryland, require a registration number from their own state. Texas sellers may accept the MTC form, but not the Streamlined Sales Tax certificate, as a resale certificate.

What happens if I use a resale certificate for personal items?

You owe the tax, and penalties can apply. California can charge a penalty of 10% of the tax or $500, whichever is greater, for each purchase made for personal gain or to evade tax, and Texas treats illegal use as a criminal offense ranging from a misdemeanor to a felony depending on the tax evaded.

The Bottom Line for Thrift and Flea Market Sourcing

A resale certificate is worth carrying when you source where sales tax is charged, which can include thrift stores, flea market vendors and estate sale companies. Get your permit sorted first, fill out the form before you shop, keep inventory and personal buys apart, and keep copies. If a store says no, Texas permit holders and California filers can recover that state's tax on their return.
