The short version (2026):
- A seller’s permit is your state’s license to collect sales tax, and selling taxable goods without one is the compliance mistake states actually chase.
- Registration is usually free: California and Texas charge nothing (verified on their official pages), though some states may ask for a security deposit or bond.
- Marketplace sellers, breathe: Amazon and Etsy collect sales tax for you in every sales-tax state now, but many states still want you registered.
- You apply where you have “nexus”: your home state first, and other states only once physical presence or enough sales create a duty there.
What a Seller’s Permit Is
Bottom line first: a seller’s permit (your state may call it a sales tax permit, sales and use tax license, or certificate of authority) is the state revenue department’s authorization for your business to collect sales tax from customers and remit it to the state. It is not optional garnish: if you sell taxable goods (and in some states, taxable services) at retail, most sales-tax states require the permit before your first sale, and selling without one is one of the few small-business paperwork gaps that comes with real penalties, because you are handling the state’s money. The good news is the price of compliance: in most states, including the two giants verified below, the permit itself is free.
This guide covers who needs one, the terminology that trips everyone, the application walkthrough, verified examples from the biggest states, and the marketplace and multi-state rules that changed everything for online sellers.
Do You Need One? (The Nexus Question)
You need a permit in any state where two things are both true: you have nexus (a connection strong enough to give the state taxing authority over you) and you make taxable sales there. Nexus comes in two flavors. Physical nexus is the classic: your home state, an office, inventory in a warehouse (including inventory a fulfillment service stores for you), employees, or regular in-person selling. Economic nexus is the post-2018 addition (from the Supreme Court’s Wayfair decision): enough remote sales into a state, commonly around $100,000 a year, though thresholds vary and several states have been revising them, creates a duty to register even with zero physical presence. The practical sequence for a new business: register in your home state before the first sale; track where your out-of-state sales concentrate; and register elsewhere only when a state’s threshold (or your inventory footprint) actually reaches you. Five states have no state sales tax at all (Alaska, Delaware, Montana, New Hampshire, Oregon), though Alaska’s local governments can tax, and sellers into other states from those five still face the other states’ rules.
Permit, License, Certificate: The Terminology Untangled
| Document | What it does | Who issues it |
|---|---|---|
| Seller’s permit (sales tax permit/license) | Authorizes you to collect and remit sales tax | State revenue department |
| Business license | General permission to operate in a city or county | Local government (fees vary by industry and city) |
| Resale certificate | Lets you buy inventory tax-free for resale | You issue it to suppliers, using your permit number |
The relationship people miss: the resale certificate is a benefit the seller’s permit unlocks. Once registered, you give suppliers a resale certificate instead of paying sales tax on inventory, because the tax gets collected once, from the end customer, by you. Misusing that certificate for personal or non-resale purchases is the abuse states audit for, so use it exactly as labeled.
How to Apply (The Generic Walkthrough)
Every state runs its own portal, but the application is the same fifteen-minute form everywhere. Before you start, have: your EIN (or SSN for sole proprietors), the legal entity name and formation details if you formed an LLC, owner/officer names and IDs, business address, start date, a description of what you sell (states use NAICS codes), and, in some states, estimated monthly sales, which can determine your filing frequency and any security deposit. Then: find your state revenue department (the IRS’s directory of state tax agencies links every one), create an account on its business portal, complete the sales-tax registration, and save the permit and account number. Most states issue the permit within days, many instantly. One honest caution for the road: registering creates a filing obligation on a schedule (monthly, quarterly, or annually), and the state expects a return even for zero-sales periods, the single most common new-seller penalty is the missed zero return, not the missed tax.
What It Costs: Verified Examples
A 50-state fee table on a blog goes stale the week it’s published, so here is the honest version: the two biggest markets, verified from their official pages, plus the pattern that covers the rest.
| State | Cost | Where and notes |
|---|---|---|
| California | $0 | Register online with the CDTFA; “there is no charge for a seller’s permit,” though a security deposit can be requested based on expected sales |
| Texas | $0 | Register with the Comptroller’s online application; no fee, though a bond may be required in some cases |
| Most other states | Free to small one-time fees | Typically $0, with a minority charging modest registration fees; your state DOR’s page states the current number |
| AK, DE, MT, NH, OR | No state sales tax | No state permit; Alaska localities can impose their own |
The takeaway for budgeting: the permit is the cheapest item on your launch checklist. The real “cost” is the ongoing obligation, collecting the right rate (state plus local), filing on schedule, and keeping exemption certificates organized.

After You Register: Collect, File, Keep
Three habits turn the permit into compliance. Collect correctly: charge the combined state-plus-local rate for the delivery location your state’s rules point to; every state DOR publishes a rate lookup, and e-commerce platforms compute it automatically once you enter your permit details. File on your schedule, including zero returns, and calendar it the day the state assigns your frequency. Keep the paper: resale and exemption certificates you accept from business customers are your defense in an audit; store them with the customer file, not in a drawer of good intentions. Display or retain the permit as your state directs, renew if your state is one of the few with renewal cycles, and update the registration when you move, add locations, or change entity type, the permit follows the business facts, and stale facts are what turn routine notices into problems. Sole proprietors who later convert to an LLC should expect to re-register: the permit belongs to the legal entity, not the brand.
Online and Marketplace Sellers: The 2026 Reality
The rules online sellers learned from 2019-era blog posts have been superseded twice, so here is the current shape. Marketplace facilitator laws now cover every sales-tax state: when you sell through Amazon, Etsy, eBay, or Walmart, the marketplace collects and remits the sales tax on those orders, not you. That kills the old fifty-registrations panic for pure marketplace sellers, but with two honest asterisks: several states still require registered sellers (or sellers with inventory in-state) to hold a permit and file returns reporting marketplace sales as facilitator-collected, and any direct sales channel, your own Shopify or website checkout, is entirely your responsibility: your permit, your collection, your returns. The economic nexus thresholds from the Wayfair era (commonly $100,000 in annual sales into a state; several states have dropped their transaction-count tests) decide when a growing direct-sales business must register beyond home; track sales by state annually and register where you actually cross lines rather than prophylactically everywhere, fifty registrations means fifty filing calendars, and unnecessary ones are pure overhead. The tax side of all this flows into the same quarterly rhythm covered in our business-structure guide; sales tax is collected money you hold in trust, and the discipline is keeping it separate from revenue in your head and your bookkeeping.
Common Seller’s Permit Mistakes
- Selling first, registering later: most states want the permit before the first taxable sale, and back-registration invites back-tax math.
- Paying a middleman site $50-$200 for a registration your state provides free; like EINs, the official portal is the product.
- Missing zero returns, the beginner penalty machine.
- Treating the resale certificate as a discount card for personal purchases, the audit classic.
- Assuming the marketplace handles everything: facilitators cover marketplace orders, not your website sales, and some states still want your registration on file.
- Ignoring inventory nexus when a fulfillment network stores your goods in new states.
- Registering everywhere “to be safe” and drowning in filing calendars the business never needed.
- Forgetting the permit is entity-specific: new LLC, new registration, even when the store name never changes.
Frequently Asked Questions
How much does a seller’s permit cost?
Usually nothing: California and Texas charge no fee (verified on their official pages), and most states follow the same pattern, though some request security deposits or bonds based on expected sales and a minority charge small registration fees. Your state DOR’s page has the current number.
Do I need a seller’s permit to sell online?
If you sell taxable goods through your own checkout, yes, in your home state from day one, and in other states once nexus reaches you. If you sell only through marketplaces like Amazon or Etsy, the marketplace collects the tax, but several states still require you to register, especially if your inventory sits in their warehouses.
What’s the difference between a seller’s permit and a business license?
The seller’s permit is the state’s sales-tax authorization; the business license is local permission to operate at all. Many businesses need both, from different governments, and neither substitutes for the other.
How long does it take to get one?
Online applications commonly issue within minutes to a few business days. The fifteen-minute preparation, EIN, entity details, sales estimates, is the slow part.
What is a resale certificate and how do I get one?
It’s the document your permit unlocks: you issue it to suppliers to buy inventory without paying sales tax, because the tax will be collected from your end customer. States provide the form; your permit number makes it valid; misuse is what auditors look for.
Do I need permits in every state I ship to?
No. You register where you have nexus: your home state, states holding your inventory, and states where your direct sales cross economic-nexus thresholds (commonly around $100,000 a year). Marketplace-only sales are handled by facilitator collection in every sales-tax state.
Register Free, File on Time, Keep the Certificates
The seller’s permit is launch paperwork at its most benign: free almost everywhere, issued in minutes, and unlocking the resale certificate that saves you real money on inventory. The compliance that matters starts after: the right rate, the filing calendar including zero months, and certificates kept like the audit evidence they are. Do the fifteen minutes before the first sale, and sales tax becomes plumbing instead of peril.
