Yes, reselling is legal in the United States, and if that's all you came for, you can stop reading here.
But you're probably not asking because you're worried about the general case.
You're worried about those twelve pairs of sneakers bought at retail, the pallet of returns from a liquidation site, and the branded skincare that a company's lawyer just sent a stern email about.
The answer you're looking for is more complicated than a "yes", though not because the law itself is complicated.
Federal law is fairly easy to comply with, and it's mostly on your side.
What actually determines whether you keep selling is a set of rules nobody voted on, written by companies rather than legislators, and enforced without anyone needing to prove you did something wrong.
Below, we'll cover what you're genuinely protected from, what the limitations of that protection are, and why the thing most likely to end a reselling business never involves a courtroom.
Key takeaways
Reselling authentic goods you legally own is protected by the first sale doctrine, a principle in US copyright and trademark law that ends a rights holder's control over an item once it has been sold. The protection doesn't cover counterfeits, stolen goods, and products you've altered or misrepresented.
Marketplace policies are stricter than legal requirements, and a suspension doesn't require anyone to prove wrongdoing in court.
How is reselling legal in the first place
The reason you can legally resell almost anything you own is the first sale doctrine.
Under Section 109 of the Copyright Act, the owner of a lawfully made physical copy can generally lend, resell, or dispose of that item without permission from the copyright holder.
Buy the book, sell the book. Buy the sneakers, sell the sneakers.
The Supreme Court settled the most contested version of this in 2013.
In Kirtsaeng v. John Wiley & Sons, the Court held 6-3 that the first sale doctrine applies to works lawfully made or purchased abroad.
Where a Thai student had family buy cheaper foreign editions of textbooks and ship them to him in the US, where he resold them at a profit.
The ruling means that wherever a copy is first made and lawfully sold, it can be resold in the US without the publisher's permission.
The same logic applies to trademark law. Unauthorized resellers are generally permitted to resell genuine products that have another party's trademark once they've bought them.
This is what makes retail arbitrage legal. Buying from a store and reselling online at a higher price is not a loophole but ordinary commerce.
Which brings us to something brands would rather you didn't know. "Unauthorized reseller" sounds like an accusation, but it's mostly a description.
It means the brand hasn't given you a dealer agreement, not that you've done anything wrong.
That said, the protection has some conditions you should be aware of before a brand's lawyer explains them to you.
The exceptions that can get you in trouble
The first sale doctrine covers genuine goods you legitimately own.
It does not cover counterfeit goods, which are one of the quickest ways to turn a reselling business into a legal problem.
Selling counterfeit items is trademark infringement whether or not you knew, and "my supplier said they were authentic" is a weak place to argue from.
Stolen goods are the obvious other category, though the more common version is subtler: liquidation lots and unverified wholesale sources that land somewhere between careless and criminal.
There are two exceptions that catch honest sellers off guard, described by courts as the "material difference" and "quality control" exceptions.
A trademarked good that's materially different from what the trademark owner sells isn't considered genuine, and a reseller who doesn't abide by the trademark holder's quality control standards can lose first sale protection too.
Material differences can be physical or non-physical, which is why brands rely on warranties, authorized reseller lists, and service plans.
Courts have routinely found that a product sold without the manufacturer's warranty is enough on its own to push it outside first sale protection.
In practice, reselling a sealed, unaltered, in-date product is on solid ground.
Repackaging it, removing batch codes, implying you're an authorized retailer, or selling something the manufacturer's warranty no longer covers is where an infringement claim gets teeth.
When this happens, brands usually send a cease and desist rather than sue.
They can limit resale at the margins but rarely ban it outright, and filing false counterfeit complaints against legitimate resellers exposes them to penalties of their own.
Marketplace rules vs. actual law
A letter from a brand's lawyer is uncomfortable but usually negotiable. A suspension from eBay or Poshmark is neither, and nobody has to prove you broke a law to issue one.
Every marketplace has its own policy on top of the legal one, and those policies are consistently getting stricter.
Certain brands are restricted outright on some platforms. Some categories require invoices or documentation before you can list at all.
Accounts get flagged by automated systems that often can't tell a counterfeit from a legitimate item photographed under bad lighting.
These are not under a trademark law. It's a private company's terms of service, enforced however that company sees fit.
Most sellers burn energy worrying about legal exposure that's statistically remote while ignoring policy risk that's close to routine.
Nobody gets sued for reselling a Coach bag from an outlet. Plenty of resellers wake up to a suspended account and no explanation of why.
There's another version of this problem that has nothing to do with authenticity. Platform metrics are cumulative, which means operational mistakes add up.
If you list the same item on two marketplaces and sell it twice, you have to cancel on one of those buyers, and that cancellation damages your account standing even though everything you did was perfectly legal.
On eBay, the damage is financial as well, since sellers rated Below Standard pay an additional 6% on final value fees.
Now that we've separated what's illegal from what simply gets you removed, let's cover the obligations that apply to everyone.
Your tax obligations as a reseller
All profit from reselling is taxable income, whether or not a platform sends you paperwork.
The paperwork threshold has moved around for years and is now settled again.
As of 2026, the federal Form 1099-K reporting threshold is more than $20,000 in gross payments and more than 200 transactions.
The One Big Beautiful Bill Act of 2025 restored this threshold, reversing the planned $600 requirement.
You can still receive a form below that, and all income is taxable whether a form arrives or not.
So what does the threshold actually tell you? Only whether the marketplace files a form with the IRS.
There's one useful exception: selling a personal item at a loss, like your old jacket for less than you paid, isn't taxable income.
Buying inventory specifically to flip is a different activity, and it's treated like one.
Sales tax used to be the bigger headache, and mostly isn't anymore. Marketplace facilitator laws now require platforms like Amazon, eBay, and Etsy to charge and collect sales tax on behalf of the sellers using them in every state with a sales tax.
Sellers are still responsible for sales made outside a marketplace, such as through their own website or in person.
Two things still depend on where you live.
A resale certificate lets you buy inventory without paying sales tax on it, on the logic that tax gets collected when the item reaches the end buyer.
And whether you need a business license to resell legally varies by state and often by city, with no federal answer to fall back on.
For both, check your state's department of revenue rather than a forum thread.
The narrow cases where reselling really is illegal
A few categories break the general rule, and they're specific enough to avoid.
Price gouging is the main one.
Federal consumer protection law doesn't address price gouging, but many states have laws carrying civil and sometimes criminal penalties, often defining excessive pricing as a 10 to 15% increase above normal rates during a declared emergency.
The trigger is usually essential goods during a declared disaster, so flipping collectibles at a steep markup isn't gouging, while flipping generators after a hurricane may well be.
Tickets are the other.
No federal law prohibits ticket resale, so states set their own rules and they vary widely: Texas has no restrictions, while New Jersey caps resale markups.
The BOTS Act of 2016 makes it illegal to use automated software to buy tickets for resale, but it doesn't ban people from reselling above face value.
Beyond that, the restricted list is roughly what you'd expect: firearms, pharmaceuticals, and anything that needs a license to distribute in the first place.
Keeping your reselling business safe on both fronts
Reselling is legal, and staying legal is mostly a documentation problem.
Buy from sources you can verify, describe condition accurately, don't imply you're an authorized dealer, and keep records good enough to reconstruct any sale a year later.
The harder part is the middle layer.
You can mostly design around legal risks, but platform standing depends on execution, and execution is messier with every marketplace you add.
Managing your listings from one place, the way Crosslist does across 11+ marketplaces with autodelist pulling sold items automatically, removes the most common way sellers damage their accounts without doing anything wrong.
Start with Crosslist and protect your account standing without adding more hours to your week.
FAQ
Is retail arbitrage legal?
Yes. Buying from a retail store and reselling online is protected under the first sale doctrine, as long as the item is authentic and you describe it accurately. Brands can't stop you from reselling genuine products they already sold.
Can a brand sue you for reselling their products?
They can try, but only in specific circumstances.
Reselling genuine, unaltered goods is protected, while selling counterfeits, materially different products, or items outside the brand's quality control standards can support a trademark infringement claim.
Do you need a business license to resell?
It depends on your state and often your city, since there's no federal requirement.
Check your state's department of revenue, which also handles resale certificates if you want to buy inventory without paying sales tax upfront.
Do you have to pay taxes on reselling income?
Yes. All profit from reselling is taxable whether or not you receive a 1099-K.
The current federal threshold for platforms to issue one is more than $20,000 in payments across more than 200 transactions, but that only affects paperwork, not what you owe.

A letter from a brand's lawyer is uncomfortable but usually negotiable. A suspension from eBay or Poshmark is neither, and nobody has to prove you broke a law to issue one.
Every marketplace has its own policy on top of the legal one, and those policies are consistently getting stricter.
Certain brands are restricted outright on some platforms. Some categories require invoices or documentation before you can list at all.
Accounts get flagged by automated systems that often can't tell a counterfeit from a legitimate item photographed under bad lighting.
These are not under a trademark law. It's a private company's terms of service, enforced however that company sees fit.
Most sellers burn energy worrying about legal exposure that's statistically remote while ignoring policy risk that's close to routine.
Nobody gets sued for reselling a Coach bag from an outlet. Plenty of resellers wake up to a suspended account and no explanation of why.
There's another version of this problem that has nothing to do with authenticity. Platform metrics are cumulative, which means operational mistakes add up.
If you list the same item on two marketplaces and sell it twice, you have to cancel on one of those buyers, and that cancellation damages your account standing even though everything you did was perfectly legal.
On eBay, the damage is financial as well, since sellers rated Below Standard pay an additional 6% on final value fees.
Now that we've separated what's illegal from what simply gets you removed, let's cover the obligations that apply to everyone.
Your tax obligations as a reseller
All profit from reselling is taxable income, whether or not a platform sends you paperwork.
The paperwork threshold has moved around for years and is now settled again.
As of 2026, the federal Form 1099-K reporting threshold is more than $20,000 in gross payments and more than 200 transactions.
The One Big Beautiful Bill Act of 2025 restored this threshold, reversing the planned $600 requirement.
You can still receive a form below that, and all income is taxable whether a form arrives or not.
So what does the threshold actually tell you? Only whether the marketplace files a form with the IRS.
There's one useful exception: selling a personal item at a loss, like your old jacket for less than you paid, isn't taxable income.
Buying inventory specifically to flip is a different activity, and it's treated like one.
Sales tax used to be the bigger headache, and mostly isn't anymore. Marketplace facilitator laws now require platforms like Amazon, eBay, and Etsy to charge and collect sales tax on behalf of the sellers using them in every state with a sales tax.
Sellers are still responsible for sales made outside a marketplace, such as through their own website or in person.
Two things still depend on where you live.
A resale certificate lets you buy inventory without paying sales tax on it, on the logic that tax gets collected when the item reaches the end buyer.
And whether you need a business license to resell legally varies by state and often by city, with no federal answer to fall back on.
For both, check your state's department of revenue rather than a forum thread.
The narrow cases where reselling really is illegal
A few categories break the general rule, and they're specific enough to avoid.
Price gouging is the main one.
Federal consumer protection law doesn't address price gouging, but many states have laws carrying civil and sometimes criminal penalties, often defining excessive pricing as a 10 to 15% increase above normal rates during a declared emergency.
The trigger is usually essential goods during a declared disaster, so flipping collectibles at a steep markup isn't gouging, while flipping generators after a hurricane may well be.
Tickets are the other.
No federal law prohibits ticket resale, so states set their own rules and they vary widely: Texas has no restrictions, while New Jersey caps resale markups.
The BOTS Act of 2016 makes it illegal to use automated software to buy tickets for resale, but it doesn't ban people from reselling above face value.
Beyond that, the restricted list is roughly what you'd expect: firearms, pharmaceuticals, and anything that needs a license to distribute in the first place.
Keeping your reselling business safe on both fronts
Reselling is legal, and staying legal is mostly a documentation problem.
Buy from sources you can verify, describe condition accurately, don't imply you're an authorized dealer, and keep records good enough to reconstruct any sale a year later.
The harder part is the middle layer.
You can mostly design around legal risks, but platform standing depends on execution, and execution is messier with every marketplace you add.
Managing your listings from one place, the way Crosslist does across 11+ marketplaces with autodelist pulling sold items automatically, removes the most common way sellers damage their accounts without doing anything wrong.
Start with Crosslist and protect your account standing without adding more hours to your week.
FAQ
Is retail arbitrage legal?
Yes. Buying from a retail store and reselling online is protected under the first sale doctrine, as long as the item is authentic and you describe it accurately. Brands can't stop you from reselling genuine products they already sold.
Can a brand sue you for reselling their products?
They can try, but only in specific circumstances.
Reselling genuine, unaltered goods is protected, while selling counterfeits, materially different products, or items outside the brand's quality control standards can support a trademark infringement claim.
Do you need a business license to resell?
It depends on your state and often your city, since there's no federal requirement.
Check your state's department of revenue, which also handles resale certificates if you want to buy inventory without paying sales tax upfront.
Do you have to pay taxes on reselling income?
Yes. All profit from reselling is taxable whether or not you receive a 1099-K.
The current federal threshold for platforms to issue one is more than $20,000 in payments across more than 200 transactions, but that only affects paperwork, not what you owe.
