To open a thrift store, you typically need a general business license, a federal Employer Identification Number, a seller’s permit from your state tax agency, a secondhand dealer permit from your city or county, zoning approval and a certificate of occupancy for your location, fire safety clearance, and usually a sign permit. The permits needed to open a thrift store span federal, state, and local levels, and the exact mix depends on your jurisdiction, but the categories below apply to nearly every store in the country.
Business License, DBA, and EIN
Start with the baseline registrations that any retail business needs. Most cities and counties issue a general business license or tax registration certificate that authorizes you to operate commercially within their boundaries. The application usually goes through your city clerk’s office or a local licensing department, and fees vary widely by jurisdiction.
If the store will operate under a name other than your own legal name, file a “Doing Business As” registration, sometimes called a trade name or fictitious business name filing. This creates the public record that connects the store name to you or your business entity, and banks will ask for it before opening a business account under the store’s name.
You’ll also need a Federal Employer Identification Number from the IRS. The nine-digit number functions as a tax ID for the business and is used for tax filings, hiring, and bank accounts. The application is free and takes a few minutes on the IRS website.1Internal Revenue Service. Get an Employer Identification Number
Seller’s Permit and Resale Certificate
Every state that collects sales tax requires retailers to hold a seller’s permit, sometimes called a certificate of authority or sales tax license. The permit registers your store with the state tax agency so you can collect sales tax from customers and remit it on a schedule. The permit itself is free in most states, though some require a refundable security deposit against taxes a closing business might owe.
A resale certificate is the companion document for the buying side. When you purchase inventory in bulk from wholesalers, liquidators, or other dealers, presenting a resale certificate exempts those purchases from sales tax, because the tax will be collected when the item is sold to the end customer. The certificate only covers goods you intend to resell, not supplies or equipment you’ll use in the store.2Multistate Tax Commission. Uniform Sales and Use Tax Resale Certificate
Failing to collect or remit sales tax is one of the fastest ways into serious trouble. Penalties generally include a percentage of the unpaid tax plus interest, and repeated violations can lead to revocation of your seller’s permit. Clean record-keeping from day one is the simplest protection during a state audit.
Secondhand Dealer Permit
This is the permit that separates thrift stores from other retail businesses. Most states and many cities require a secondhand dealer permit for any business that buys or accepts used goods for resale. The purpose is to prevent stolen property from being laundered through resale shops, and the requirements reflect that concern.
Plan to maintain a detailed transaction log for every item you acquire from the public. Typical requirements include a description of each item, any serial numbers, and the name and identification of the person who brought it in. Some jurisdictions require this data to be uploaded to a law enforcement database so police can cross-reference inventory against theft reports in near real-time.
Many jurisdictions also impose a mandatory holding period before an acquired item can go on the sales floor. In some areas the hold runs as long as 30 days from the date you report the acquisition to local police. New owners whose business model depends on fast inventory turnover often get caught here: a multi-week hold ties up capital and floor space.
The application itself commonly requires fingerprinting and a criminal background check for all owners, and sometimes for managers. Background check fees typically run $30 to $70 per person, and the annual permit fee usually falls between $100 and $500 depending on jurisdiction. Violations of secondhand dealer laws can carry misdemeanor charges, so the record-keeping requirements are not optional.
Zoning, Certificate of Occupancy, Fire, and Sign Permits
Confirm the property is zoned for retail before you sign a lease. A thrift store in a space zoned residential or industrial will be denied a business license, and you’ll be stuck with a lease you can’t use. Your local planning or zoning department can tell you whether a specific address allows retail operations and whether you need a zoning permit or variance to proceed.
Once you have a suitable location, you’ll likely need a certificate of occupancy. This document confirms the building meets local building codes and is safe for the way you plan to use it, and getting one typically requires passing inspections for electrical, plumbing, fire safety, and structural soundness. If the space previously housed a different type of business, expect a more involved process because the building may need modifications to meet retail occupancy standards.
Fire safety clearance is a separate layer. A fire marshal or local fire inspector will check that your store has adequate exits, properly maintained fire extinguishers, working sprinklers if required, and clear evacuation paths.
If you plan to put a sign on the building, most cities require a separate sign permit regulating size, height, placement, and sometimes lighting. Fees and review processes vary, and you should budget time for both a zoning review and a building department review. Putting up a sign without a permit reliably produces a fine and an order to remove it.
ADA Accessibility
The Americans with Disabilities Act isn’t a permit you apply for, but it will come up during inspection and in customer complaints, so it belongs on your checklist. The ADA applies to all retail businesses open to the public. Your layout needs a minimum clear aisle width of 36 inches between fixed shelving or display units, with 42 inches preferred where possible.3U.S. Department of Justice. ADA Standards for Accessible Design Title III Regulation 28 CFR Part 36 Entrance doors, checkout counters, fitting rooms, and restrooms all have specific clearance and height requirements, and building inspectors may flag issues during the certificate of occupancy process.
Consumer Product Safety Rules
Federal consumer product safety laws apply to thrift stores like any other retailer. The Consumer Product Safety Commission has stated plainly that its regulations cover anyone who sells or distributes consumer products, including thrift stores, consignment shops, and charities.4GovInfo. Resellers Guide to Selling Safer Products Selling a recalled product is illegal.
Children’s products get the heaviest scrutiny. You cannot sell cribs, play yards, baby walkers, baby bath seats, or other durable infant products that fail current mandatory safety standards. Children’s sleepwear must meet flammability standards. Drawstrings on children’s outerwear hoods and necks are a recognized strangulation hazard, and small parts that could choke a young child make a toy unsaleable.5U.S. Consumer Product Safety Commission. Resale/Thrift Stores Information Center Checking the CPSC recall database before putting inventory on the floor, especially nursery furniture, car seats, and small electronics, is the practical way to stay on the right side of this.
Used Bedding Restrictions
Selling used mattresses, pillows, and bedding is either heavily regulated or outright banned depending on where you operate. Many states require that any secondhand mattress be professionally sterilized and disinfected using a process approved by the state health department before resale. After sanitization, the item must carry a visible tag identifying the filling materials, stating that the item is secondhand, and displaying the sanitization permit number. Some states require a separate permit specifically for the sterilization process, and a handful prohibit the resale of used mattresses entirely.
The rules are strict enough that many thrift stores simply refuse to accept mattresses and box springs. If you want to sell used bedding, research your state’s requirements before accepting a single item.
Insurance
Insurance isn’t technically a permit, but many landlords and some licensing offices require proof of coverage before you can open the doors. At minimum you need general liability insurance, which protects the business if a customer is injured in your store or by a product you sold. Commercial leases often mandate a specific minimum coverage amount.
If you hire employees, nearly every state requires workers’ compensation insurance. Thresholds vary: some states require it with your first employee, others wait until you have four or more. Operating without required coverage can bring fines, criminal charges, and personal liability for workplace injuries.
If You’re Opening as a Nonprofit
Many thrift stores operate as part of a tax-exempt nonprofit under Section 501(c)(3) of the Internal Revenue Code. If you go that route, the store must serve the organization’s charitable purpose, no earnings can benefit any private individual, and the organization cannot participate in political campaigns and can only engage in limited lobbying.6Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations
A common question is whether thrift store sales trigger unrelated business income tax. The IRS excludes thrift store income from UBIT when substantially all of the merchandise was donated, which the IRS has interpreted to mean at least 85% of goods sold. Alternatively, if the store is staffed entirely by unpaid volunteers, the income is excluded from UBIT regardless of how the inventory was acquired.7Internal Revenue Service. Unrelated Business Income Tax Exceptions and Exclusions
Nonprofit status does not exempt you from any of the other permits above. You still need a seller’s permit in most states, a secondhand dealer permit where required, and compliance with zoning, fire safety, and CPSC rules. Tax-exempt status relates to income tax, not to operating permits.
Documents to Gather Before You Apply
Most permit applications ask for the same core documentation, so gathering it upfront prevents delays across multiple filings:
- Federal Employer Identification Number, obtained free from the IRS online1Internal Revenue Service. Get an Employer Identification Number
- Signed lease or proof of property ownership, which confirms the physical location for zoning and licensing
- Government-issued photo ID for all owners and sometimes managers, especially for secondhand dealer applications involving background checks
- Floor plan or interior layout showing aisle widths, exits, fire extinguisher placement, and ADA compliance
- Business entity documents such as articles of incorporation, an LLC operating agreement, or a partnership agreement
- DBA filing receipt if operating under a trade name
Applications go to different offices. Your city clerk or licensing department handles business licenses, the state tax agency handles seller’s permits, and the local police department often processes secondhand dealer permits. Many jurisdictions accept online applications, but fire and building inspections still require scheduling an in-person visit. Timelines run from same-day for simple registrations to several weeks for permits requiring inspections or background checks. Once issued, most jurisdictions require you to display permits visibly inside the store, and annual renewals are standard for business licenses and secondhand dealer permits. Letting a permit lapse, even by a few days, can trigger fines or a forced closure until you catch up.
