In most U.S. states, yes, you need a seller's permit (also called a sales tax permit or sales tax license) to sell taxable goods online, even if you only sell on Etsy or Amazon and those platforms already collect tax for you. The permit is what legally authorizes you to charge sales tax in your home state, and many states require you to register even when a marketplace remits the tax on your behalf. The big exceptions are the five states with no statewide sales tax (Alaska, Delaware, Montana, New Hampshire, and Oregon), where there's no permit to get.

That short answer hides a trap that catches almost every new seller, so let's unpack it properly.

What a seller's permit actually is (and isn't)

A seller's permit is a registration with your state's tax authority (often called the Department of Revenue or, in California, the CDTFA). It does two things:

  1. It gives you legal authority to collect sales tax from buyers in your state.
  2. It often comes with a resale certificate, which lets you buy inventory wholesale without paying sales tax yourself (you'll collect it from the end customer instead).

It is not the same thing as a business license. A business license is permission to operate a business in your city or county. A seller's permit is specifically about sales tax. Many online sellers need both. We cover the license side in detail in do I need a business license to sell online, so read that next if you're starting from zero.

Seller's permit Business license
Issued by State tax authority City or county (sometimes state)
Purpose Collect & remit sales tax Permission to operate
Typical cost $0–$100 (many states free) $15–$400/year
Renewal Usually permanent or auto Usually annual
Who needs it Anyone selling taxable goods Most businesses, varies by city

The marketplace facilitator catch (this is the part everyone misses)

Here's where the top Google results leave you hanging. Since 2018, "marketplace facilitator" laws require platforms like Amazon, Etsy, eBay, Walmart, and Poshmark to collect and remit sales tax on your behalf for sales made through their platform. That's real, and it's why your Etsy buyer in Ohio gets charged tax automatically without you lifting a finger.

So you'd think: the platform handles tax, so I don't need a permit, right?

Not so fast. Two things are still true:

  • Many states still require you to register for a seller's permit even though the marketplace remits the tax. The platform is just the collector; the state still wants you on file. Some states (like Connecticut) require marketplace sellers to file an annual return once they cross the economic nexus threshold, even when they owe $0.
  • The protection only covers platform sales. The moment you sell anywhere off the marketplace, you're on your own.

That second point is the whole ballgame, so it gets its own section.

Platform-only vs. your own store: the split that decides everything

Whether you need to actively manage a seller's permit comes down to where you sell.

If you sell ONLY on marketplaces (Etsy, Amazon, eBay)

The marketplace collects and remits sales tax for you in every state that has these laws (which is all 45 sales-tax states plus D.C.). You still:

  • Likely need to register for a permit in your home state (check the 5-minute method below).
  • Don't need to collect or remit tax yourself for those platform sales, just verify the platform is set up correctly in your seller dashboard.

This is the simplest path, which is partly why new makers start on Etsy. If that's you, our walkthrough on how to open an Etsy shop from product ideas to sales covers the setup end to end.

If you sell on your OWN store (Shopify, WooCommerce, social DMs)

Now you are the seller of record. There's no facilitator. You must:

  • Get a seller's permit in your home state.
  • Collect sales tax yourself on orders shipped to customers in any state where you have nexus (more on nexus below).
  • File and remit that tax on a monthly, quarterly, or annual schedule.

Most modern sellers run both: an Etsy shop and a Shopify site. In that case the marketplace covers the marketplace orders, and you handle tax on your direct Shopify orders separately. Don't assume Etsy's collection covers your Shopify sales. It doesn't.

The nexus question: home state vs. every state

"Nexus" just means a connection strong enough that a state can require you to deal with its sales tax. You have it two ways:

Physical nexus — you live, work, store inventory, or have employees in the state. Your home state is automatic. This is why almost everyone needs at least one permit.

Economic nexus — you sell enough into a state to trigger an obligation even without setting foot there. The common threshold is $100,000 in sales OR 200 separate transactions into that state in a year, though the trend is moving toward $100,000-only (16+ states have dropped the 200-transaction rule as of 2026, and a few outliers like New York use $500,000). The official threshold list is maintained by each state, and the Streamlined Sales Tax project is a good neutral reference.

The practical takeaway for a solo seller:

  • You almost certainly need a permit in your home state. Start there.
  • You probably don't need permits in 49 other states on day one. You only register elsewhere once you actually cross that state's threshold with your direct (non-marketplace) sales. Marketplace sales usually don't count toward your own economic nexus in most states because the platform already handled them, but a handful of states do count gross marketplace sales toward the threshold, so check before you scale.

What about digital products, dropshipping, and services?

These three cases trip people up because the rules differ from "ship a physical box."

Digital products (eBooks, courses, templates, printables, software). Taxability varies wildly by state. Some states fully tax digital goods, some exempt them, and some only tax certain types. If you sell digital downloads on Etsy, the marketplace still handles the tax where it applies. If you sell a course on your own site, you need to research each state where you have nexus. Don't assume "it's digital so it's tax-free" because that's only true in some states.

Dropshipping and print-on-demand. Here's the hidden nexus problem: your supplier or POD printer's warehouse can create physical nexus for you in that state, even though you never go there. If your Printful or supplier facility is in, say, North Carolina, you may have nexus in North Carolina. You'll also typically need a resale certificate so your supplier doesn't charge you sales tax on goods you're reselling. Get your home-state permit, then ask your supplier exactly which states they fulfill from.

Pure services (consulting, design, coaching). Most states don't tax services, so you often don't need a seller's permit, though some states tax specific services. If you sell services plus any physical or digital product, you're back to needing one.

How to get your seller's permit: a 5-minute state check

You don't need a lawyer or a $300 filing service for this. Here's the do-it-yourself version.

  • [ ] Search "[your state] seller's permit" or "[your state] sales tax registration." Go straight to the official .gov site (e.g., your Department of Revenue or CDTFA). Ignore the ads from filing mills.
  • [ ] Have these ready: your legal name and address, your business name, your EIN (or SSN if you're a sole proprietor without an EIN), your business start date, and an estimate of monthly sales. Need an EIN? See do I need an EIN for a sole proprietorship.
  • [ ] Register online. Most states issue the permit instantly or within a few business days. Cost is usually $0–$100; many states are free.
  • [ ] Save your permit number. You'll plug it into Shopify's tax settings and use it to claim resale exemptions with suppliers.
  • [ ] Note your filing frequency. The state assigns you monthly, quarterly, or annual filing. Put the due dates in your calendar now. Filing $0 returns when nothing is owed is still required in most states, and missing them is the #1 cause of penalties.
  • [ ] Confirm marketplace settings. In your Etsy/Amazon dashboard, verify the platform is collecting tax (it is, by default) so you're not double-collecting.

That's genuinely it. For most solo online sellers, the whole process is a free, 15-minute online form.

What happens if you skip it?

Selling taxable goods without a permit means you're collecting tax you're not authorized to collect, or worse, not collecting tax you legally owe. Consequences vary by state but typically include:

  • Back taxes owed out of your own pocket (the state assumes the price included tax you should have collected).
  • Penalties and interest, often 10–25% on top of the unpaid amount.
  • Inability to claim resale exemptions, so you overpay on inventory.
  • For larger or willful cases, fines and, rarely, misdemeanor charges.

The risk is low when you're tiny, but it compounds. The cheapest, least stressful move is to register in your home state before your first sale. It's free in most states and removes the one piece of legal anxiety that actually has teeth.

Frequently Asked Questions

Do I need a seller's permit for every state I sell to, or just my home state?

Just your home state, to start. You only register in other states once you cross that state's economic nexus threshold (commonly $100,000 in sales or 200 transactions) with your own direct sales. Marketplace sales are usually handled by the platform and don't typically obligate you elsewhere, though a few states count them toward the threshold.

Does selling on Amazon or Etsy mean I don't need a permit at all?

Not necessarily. The marketplace collects and remits tax on your platform sales, but many states still require you to register for a permit in your home state, and some require an annual filing even when you owe nothing. And the platform's protection ends the instant you sell on your own Shopify store or via social media.

Is a seller's permit the same as a business license?

No. A seller's permit is a state-level sales-tax registration. A business license is local permission to operate, usually from your city or county. Most online sellers need both. The IRS also distinguishes federal tax IDs from these; if you hire or form an LLC, you'll want an EIN too.

Do digital products and services need a seller's permit?

It depends on your state. Many states tax digital goods (eBooks, courses, software) and a few tax specific services, but plenty exempt them. If you sell anything taxable in your state, you need the permit. Pure-service businesses often don't, but check your specific state's rules before assuming.

How much does a seller's permit cost?

In most states, it's free or under $100, and it's usually issued instantly or within a few business days online. Avoid third-party filing services charging $150+ for something you can do yourself in 15 minutes on your state's official .gov site.
