To get a resale license, register for a seller’s permit with the tax authority in each state where you have a sales tax obligation, then use the sales tax number that permit gives you on resale certificates you hand to your wholesale suppliers. Most states let you register online for free, and the permit number arrives within one to three business days. The “resale license” people search for is really two documents working together: the seller’s permit (your state registration that lets you collect sales tax) and the resale certificate (the form you give vendors so they skip the sales tax on your wholesale purchases).
Seller’s Permit and Resale Certificate: Know the Difference
Getting these two mixed up is the first mistake new sellers make. The seller’s permit is your registration with the state tax authority. It gives you the legal right to sell taxable goods, collect sales tax from buyers, and send that tax to the state. The resale certificate is a form you fill out and give to a supplier, telling them not to charge you sales tax because you plan to resell the item.
You need the permit first. The sales tax ID number printed on your permit is what makes any resale certificate you later issue valid. The flow in practice: register, get your sales tax ID, write that ID on resale certificates when buying inventory, charge sales tax to your end customer, remit what you collected to the state. Tax gets paid once, at the final sale.
Do You Actually Need One
Any business selling tangible goods needs a seller’s permit in each state where it has a tax obligation. That includes brick-and-mortar shops, online sellers, wholesalers, and manufacturers of finished products. If you buy raw materials that become part of a product you sell, those purchases also qualify for resale treatment.
Whether you owe registration in a given state depends on nexus. Physical nexus is simple: an office, warehouse, inventory, or employees in that state. Economic nexus is the one that catches online sellers off guard. After the Supreme Court’s 2018 decision in South Dakota v. Wayfair, states can require you to register once your sales into that state cross a threshold even if you have no physical presence there. The most common threshold is $100,000 in annual sales or 200 transactions, though some states set it higher.
Five states have no statewide sales tax at all and do not issue seller’s permits in the usual sense: Alaska, Delaware, Montana, New Hampshire, and Oregon. Everywhere else, if you have nexus, you register.
Selling on marketplaces changes the math a little. Amazon, Etsy, and similar platforms collect and remit tax on sales made through them in most states. If you also sell through your own website, that revenue still counts toward your nexus thresholds, so you can end up owing registration based on direct sales even when the marketplace handles its share.
What to Gather Before You Apply
Pull these together before you open the application:
- Federal identification. LLCs, partnerships, and corporations need an Employer Identification Number from the IRS. Form your entity with the state first, then apply for the EIN. Sole proprietors can usually use a Social Security Number.1Internal Revenue Service. Get an Employer Identification Number
- Business formation documents: articles of incorporation, partnership agreements, or LLC operating agreements, depending on your structure.
- Owner and officer information: names, addresses, Social Security Numbers, and contact details for every partner, member, or corporate officer.
- A description of what you sell and how, along with your NAICS code (the industry classification number states use to categorize businesses).
- Revenue projections. Estimated monthly taxable sales and total annual revenue. The state uses these to set your filing frequency.
- Bank routing and account numbers for the account you’ll remit tax payments from.
Make sure the business name on your application matches exactly what you filed with your state’s business registration office. Name mismatches are one of the most common reasons applications get flagged or delayed.
How to Apply
Nearly every state offers online registration through its department of revenue or tax authority. Create an account, enter your information, electronically sign, and you’ll usually have your permit number within one to three business days. Paper filing still exists but takes anywhere from a couple of weeks to six weeks depending on the state’s backlog. File online if you need to start selling soon.
Most states charge nothing for the permit. A few charge small fees, generally under $100. The cost to watch for is a security deposit. If you have any history of tax delinquency, or sometimes as a default for new registrants, the state may require a refundable deposit to guarantee future payments. Amounts are calculated from your estimated tax liability and vary widely. The deposit comes back after you build a clean filing record, typically one to three years in.
Once your application is approved, the state assigns your filing frequency based on sales volume. High-volume sellers file monthly, moderate sellers quarterly, low-volume sellers annually. You must file every period you’re registered, even when you have zero sales. Skipping a return because nothing happened that quarter is a common early mistake, and many states charge a minimum penalty for a late filing regardless of whether tax was owed.
Using Your Resale Certificate With Suppliers
With the permit in hand and your sales tax ID assigned, you can start issuing resale certificates. The certificate tells a vendor not to charge you sales tax because the purchase is for resale. You fill in your business name, address, sales tax permit number, a description of what you’re buying, and your signature affirming the purchase is genuinely for resale. The vendor keeps the certificate on file as their justification for not collecting tax.
The certificate only covers goods you actually plan to resell. Office furniture, cleaning supplies, equipment for your own use: none of that qualifies, and buying it tax-free with a resale certificate is fraud. States treat it as such.
Vendors can refuse a certificate, even a valid one. They bear the audit liability if the certificate turns out to be invalid, so some play it safe. If a supplier refuses yours and charges you tax on a true resale purchase, you can file a refund claim with the state tax authority. You generally need to be registered in that state for the claim to succeed.
Buying From Out-of-State Vendors
Buying inventory across state lines adds friction. Most states accept out-of-state resale certificates; some don’t, and the specifics differ.
Two multistate forms cut down on the paperwork. The Multistate Tax Commission publishes a Uniform Sales and Use Tax Resale Certificate accepted by 36 states.2Multistate Tax Commission. Uniform Sales and Use Tax Resale Certificate The Streamlined Sales Tax Certificate of Exemption works across all 23 SST member states.3Streamlined Sales Tax. Exemptions Neither is universal. Check whether the state you’re buying from accepts the form you plan to use.
When filling out either multistate certificate, you’ll need a sales tax registration number. If you’re registered in the state where the purchase is being made, use that number. Otherwise your home state’s number is usually accepted, though a few states insist on their own registration before honoring the exemption.
Drop Shipping
Drop shipping creates a three-way situation: a manufacturer ships directly to your customer, you never touch the product, and the manufacturer wants a resale certificate from you. The complication is the ship-to state. Most states let the manufacturer accept your home-state certificate, but roughly ten states take a stricter line and require you to provide that state’s own registration number. If you drop ship, verify the rules in every state where your manufacturers deliver.
Keeping the Permit in Good Standing
Your permit stays active only as long as you file on time and keep your information current. The sales tax you collect isn’t yours; it’s held in trust for the state, and spending it as operating cash is both financially risky and, in some states, a criminal offense.
Resale certificates have no universal expiration period. Some states issue certificates that never expire as long as the information stays accurate; California and Arizona treat them as valid indefinitely. Others require renewal. Florida issues new certificates every year. Regardless of formal rules, a certificate becomes invalid the moment the information on it is wrong, so a change in business name, address, ownership, or permit number means you need to send fresh certificates to every supplier you buy from.
On the recordkeeping side, keep a copy of each resale certificate you’ve issued matched to the invoices it covers, and keep organized sales records showing date, amount, tax collected, and item description for every transaction. The standard sales tax audit window is three years from the filing date, though about a dozen states extend it to four. Four years of records covers the longest standard window; if the state suspects fraud or you never filed for a given period, there’s generally no time limit.
When something about your business changes (name, address, ownership structure, product line) you typically have 20 to 30 days to update your registration. Some changes, such as converting from a sole proprietorship to an LLC, require canceling the old permit and applying for a new one.
What Misuse Costs You
Using a resale certificate to buy personal items tax-free is the fastest route to losing your permit. Civil consequences usually include the unpaid tax, interest from the original due date, and an additional penalty. That added penalty commonly runs 10% of the unpaid tax or a flat amount per fraudulent certificate, whichever is greater, with some states setting a floor around $500 per transaction.
Fraudulent use is generally a misdemeanor on first offense. Repeated or large-scale misuse can be charged as tax evasion, a felony in many states. A fraud finding typically results in revocation of your seller’s permit, which ends your ability to operate a resale business legally.
