Short answer: in most U.S. cities you do not need a general business license to open an Etsy, Shopify, Amazon, or eBay shop and make your first few sales. What actually trips up online sellers is a sales tax permit (often free) once you cross a state's threshold, plus a home-occupation permit in some cities and cottage food rules if you sell food. The license question depends on three things: where you live, what you sell, and how much you earn — not on the platform itself.

Let's untangle the four things people lump together, then go platform by platform so you know exactly what applies to you.

The 4 things sellers confuse (they are not the same)

Almost every "do I need a license" panic comes from mixing up four separate documents. Knowing which is which solves half the problem.

Document What it actually does Who issues it Typical cost
General business license Permission to operate a business in a city/county City or county clerk $0–$100/yr
Sales tax permit (seller's permit) Lets you collect & remit sales tax State tax/revenue dept. Usually free
Home-occupation permit Allows running a business from your home City zoning office $25–$125
LLC Legal entity that gives liability protection Secretary of State $50–$520 to form

Three points that clear up most confusion:

  • An LLC is not a business license. Forming an LLC creates a legal entity and shields your personal assets — it does not grant permission to operate. You can have an LLC and still need a city license, and you can have a license with no LLC.
  • A business license is not liability protection. It's just permission. If you want to protect your house and savings if something goes wrong, that's the LLC's job, not the license's.
  • A sales tax permit is the one most online sellers genuinely need — and it's the one most often skipped, because people assume "I have no storefront, so no tax."

Do you need one? A 3-question self-check

Run through these. If you answer "no" to all three, you almost certainly don't need anything yet beyond keeping records.

  1. Am I trying to make a profit (not just a hobby)? If you're selling old stuff from your closet or occasionally gifting crafts for cost, the IRS may treat it as a hobby. The IRS looks at whether you operate in a businesslike way and intend to earn a profit (a common rule of thumb: profit in 3 of the last 5 years presumes a business). Once you're clearly running a business, licensing becomes relevant.
  2. Does my city require a general business license for home-based businesses? Many do; many don't. This is a 10-minute check — search "[your city] business license" or call the city clerk.
  3. Will I sell taxable goods to customers in my own state? If yes, you likely need a state sales tax permit before you cross the threshold (more below).

If you said yes to #2 or #3, keep reading for the specifics.

Platform by platform: what actually applies

Here's the nuance the generic guides miss. The platform changes who collects sales tax, which changes your real compliance burden.

Etsy

Etsy is a marketplace facilitator, which means under state marketplace-facilitator laws Etsy automatically calculates, collects, and remits sales tax on orders shipped to most U.S. states — you don't lift a finger for those orders. That removes the biggest reason a hobby Etsy shop would need a sales tax permit. You may still want one if you also sell off-Etsy (craft fairs, your own site), and your city may still want a general or home-occupation license. New to Etsy? See our step-by-step on how to open an Etsy shop.

Amazon

Same deal — Amazon collects and remits sales tax as a marketplace facilitator in the states that have those laws. You typically don't register for a sales tax permit just to sell on Amazon. Exceptions: if you run FBA and Amazon stores your inventory in a warehouse in another state, you may create "nexus" there, which can trigger registration obligations. High-volume FBA sellers should talk to an accountant about which states they have physical nexus in.

eBay

eBay also operates as a marketplace facilitator and collects/remits sales tax on most U.S. transactions. Casual sellers clearing out a garage are usually fine; once you're sourcing inventory to resell at a profit, you're a business and the self-check above applies.

Shopify (and your own website)

This is the one that's different. Shopify is not a marketplace facilitator — it's your own store on your own domain. You are responsible for collecting and remitting sales tax, which means you generally do need a sales tax permit in your home state and any state where you cross the economic-nexus threshold. Shopify gives you tools to calculate tax, but the legal responsibility (and the permit) is yours. If a store on your own domain is the plan, start with our guide on how to start an e-commerce business.

Bottom line: on Etsy/Amazon/eBay the platform handles sales tax for you; on Shopify or your own site, you handle it yourself.

The real triggers that DO require a permit or license

Sales tax permit thresholds (economic nexus)

Every state where you sell can require you to register once you cross its economic nexus threshold — most commonly $100,000 in sales OR 200 transactions into that state in a year (some states are $500,000, and a few dropped the transaction count). But remember: if all your sales go through Etsy/Amazon/eBay, the marketplace already remits that tax, so the threshold rarely lands on you. If you sell on Shopify/your own site, you must register in your home state first and watch other states as you grow. We go deeper on this in do you need a seller's permit to sell online.

Cottage food laws (selling food/baked goods)

If you sell homemade food — jams, cookies, candles-are-fine-but-edibles-are-not — almost every state has a cottage food law that requires registration or a permit, capped revenue (often $25,000–$75,000/yr), an approved product list, and specific labeling. This is non-negotiable; food is regulated even at hobby scale.

Home-occupation permit

Running the business from your home? Many cities require a home-occupation permit to confirm you're not creating traffic, signage, or nuisance. It's cheap ($25–$125) but skipping it is a common citation.

Regulated products

Alcohol, CBD/hemp, supplements, cosmetics, firearms accessories, children's products, and electronics can carry federal or state-specific licensing on top of everything above. If you sell anything ingested, applied to skin, or safety-regulated, check the rules for that category specifically.

What happens if you sell without a license?

For a small hobby-level shop, the realistic worst case isn't dramatic — but it's not zero:

  • City business license: A warning, then fines that often run $50–$500, sometimes per day of non-compliance or back-dated to when you started.
  • Sales tax (the costly one): If you should have collected sales tax and didn't, the state can come after the uncollected tax plus penalties and interest — and that's money out of your pocket since you can't retroactively charge past customers.
  • Cottage food / regulated goods: Cease-and-desist orders and steeper fines, because it's a health/safety issue.
  • Platform risk: Etsy, Amazon, and Shopify can suspend accounts that violate their seller policies or local law.

The pattern: enforcement scales with revenue and risk. The fix is cheap (most permits are free or under $100), so there's little reason to operate exposed once you're past the hobby stage.

Selling internationally? One extra thing to know

If you ship to the EU, UK, Canada, or Australia, you may eventually owe VAT/GST there. Marketplaces like Etsy/Amazon often collect this VAT at checkout for you — but on your own Shopify store, large cross-border volume can require you to register for VAT/GST in those regions. For most hobby sellers this is a "later" problem, but it's worth knowing it exists before your first big overseas order.

Your quick-start checklist

  • [ ] Decide: hobby or business? (Run the 3-question self-check.)
  • [ ] Search "[your city] + business license" — register if required.
  • [ ] Check your city's home-occupation permit rules if working from home.
  • [ ] If selling on Shopify/your own site: get a sales tax permit in your home state (usually free).
  • [ ] If selling only on Etsy/Amazon/eBay: confirm the marketplace remits sales tax (it almost certainly does) and keep records.
  • [ ] Selling food? Look up your state's cottage food law first.
  • [ ] Selling regulated products? Check federal/state rules for that category.
  • [ ] Decide separately whether you want an LLC for liability protection (different decision entirely).

When in doubt, the U.S. Small Business Administration has a license-and-permit lookup by state.

Frequently Asked Questions

Do I need a business license if I'm just selling as a hobby?

Usually no. If you're occasionally selling at cost or clearing out personal items with no real profit motive, the IRS may treat it as a hobby and most cities won't require a license. The moment you're operating to earn a profit on a recurring basis, you've crossed into "business," and the self-check above applies.

What's the difference between a business license and a sales tax permit?

A business license is permission from your city or county to operate at all. A sales tax permit (seller's permit) is a state registration that lets you collect and remit sales tax. They're issued by different governments for different reasons — many online sellers need the tax permit but not a general license, or vice versa.

Do I need a license in every state I sell to?

No — you're licensed where you're physically located. Other states only matter for sales tax, and only once you cross their economic-nexus threshold (often $100K or 200 transactions). And if you sell through Etsy, Amazon, or eBay, the marketplace already remits that tax, so other-state thresholds rarely fall on you.

Does forming an LLC mean I have a business license?

No. An LLC is a legal entity that protects your personal assets; it does not grant permission to operate. You may still need a city business license, a home-occupation permit, and a sales tax permit even with an LLC in place. They solve different problems.

Do I need a license to sell handmade crafts on Etsy?

For non-food crafts, usually not at hobby scale — Etsy remits your sales tax automatically, and many cities don't license small home businesses. Check your city's rules and get a home-occupation permit if required. If you sell handmade food, that's a different story: your state's cottage food law almost certainly requires registration.
