In most states, you need a permit to sell at a flea market before you set up your first booth. The core requirement is a seller’s permit from your state’s tax agency, which registers you to collect and remit sales tax. Depending on the city or county, you may also need a local business license, and certain products, such as prepared food, live plants, or used goods, can trigger additional permits on top of that.
The Seller’s Permit
A seller’s permit, sometimes called a sales tax license or resale license, is issued by your state’s department of revenue or equivalent tax agency. It authorizes you to collect sales tax from buyers and obligates you to send that money to the state on a regular schedule. Almost every state that charges sales tax requires one before your first sale, even if you only plan to sell at a single weekend market.
Some states carve out narrow exemptions for truly occasional sellers, like someone holding a one-time garage sale. Those exemptions rarely cover a person who buys merchandise specifically to resell it, or who shows up at multiple flea markets over the course of a year. If you plan to sell more than once, assume you need the permit.
Five states have no statewide sales tax and don’t require a seller’s permit for sales tax purposes: Alaska, Delaware, Montana, New Hampshire, and Oregon. Even in those states, local jurisdictions can impose their own sales taxes or business license requirements, so check before assuming you are in the clear.
Local Business Licenses
Beyond the state seller’s permit, many cities and counties require a separate business license to operate within their borders. Some issue temporary licenses valid for a set number of days, which can work well for vendors who only sell at occasional events. Fees range widely, anywhere from under $25 to several hundred dollars, depending on the municipality.
The flea market operator is often the best starting point for figuring out exactly which local permits apply at a specific location. Many operators keep a checklist of requirements or can point you to the right local agencies.
Permits Tied to What You Sell
Certain product categories carry their own permit requirements on top of the general seller’s permit.
- Prepared food. Selling anything you have cooked, baked, or assembled for consumption typically requires a permit from the local health department, plus compliance with food-handling and sanitation rules.
- Plants and nursery stock. Many states require anyone selling live plants to register with the state department of agriculture, even at a flea market.
- Used goods. A number of cities and counties require a secondhand dealer license if you regularly buy and resell used merchandise. These laws are designed to deter the sale of stolen property, and they often require keeping records of where you acquired each item.
Registering a Business Name
If you plan to sell under a business name rather than your own legal name, most states require you to register that name, often called a Doing Business As or DBA filing, with your county clerk or secretary of state. This is typically inexpensive and takes only a few minutes. Skipping it can create problems when you try to open a business bank account or file taxes.
How to Apply for a Seller’s Permit
Most states let you apply online through the revenue department’s website. You will typically need to provide your legal name (or business name), a physical mailing address, a description of the products you plan to sell, and either your Social Security number or a federal Employer Identification Number. Many states process online applications within a few days; some issue the permit number immediately.
An EIN is a tax identification number the IRS assigns to businesses, and you can apply for one at no cost directly on the IRS website.1Internal Revenue Service. Employer Identification Number Even if you are a sole proprietor who could technically use your Social Security number, getting an EIN keeps your personal number off business paperwork that wholesalers and other vendors may see.
Most states issue seller’s permits for free, though a handful charge a fee. Once approved, you will receive either an electronic confirmation or a physical certificate. Keep it accessible at your booth. Inspectors can ask to see it, and flea market operators sometimes check for compliance as well.
Selling without a required permit does not eliminate the tax obligation; it adds penalties on top. States can assess back taxes, interest, and fines for unregistered selling, and in some jurisdictions operating without a permit is a misdemeanor. The permit itself is usually free or cheap, so there is no financial upside to skipping it.
Using the Permit to Buy Inventory Tax-Free
Once you have a seller’s permit, you can use it to purchase inventory from wholesalers without paying sales tax on those purchases. The mechanism is a resale certificate, a signed document you give to the supplier stating that the goods are intended for resale, not personal use. Sales tax gets collected when the item reaches the final consumer, so it is not charged at the wholesale stage.
The rule only applies to merchandise you actually resell. If you pull something from your inventory for personal use or give it away as a promotion, you owe use tax on that item and need to report it on your next sales tax return. Misusing a resale certificate to dodge tax on personal purchases is a quick way to trigger penalties in an audit.
What a Permit Does Not Authorize
A seller’s permit lets you collect tax. It does not make otherwise-illegal sales legal. Two categories are worth knowing about before you stock your booth.
Recalled consumer products cannot be resold. Section 19 of the Consumer Product Safety Act bars the resale of recalled goods, and the Consumer Product Safety Commission focuses heavily on children’s products such as drop-side cribs, children’s jewelry that exceeds lead limits, and items with small-parts choking hazards for children under three.2Consumer Product Safety Commission.

The CPSC’s recall list at cpsc.gov is searchable and free.
Counterfeit merchandise is a federal crime under 18 U.S.C. ยง 2320. A first offense for an individual can bring a fine of up to $2 million and up to 10 years in prison; a second offense doubles the maximum to $5 million and 20 years.3Office of the Law Revision Counsel. 18 USC 2320 – Trafficking in Counterfeit Goods or Services “I didn’t know they were fake” is not a reliable defense when the purchase price was a fraction of the genuine article’s wholesale cost.
Liability Insurance the Market May Require
Many flea market operators require vendors to carry general liability insurance, so this can be a de facto condition of setting up. Typical minimum coverage requirements range from $500,000 to $1 million per occurrence. Short-term vendor policies are available from several insurers and are usually not expensive for a low-risk booth. Even where a market does not require coverage, a policy pays the legal and medical costs if a customer is hurt at your booth or by something you sold.
