Most resellers don't form an LLC right away. You start with a garage sale haul, a few eBay listings, maybe a Poshmark closet. Money is coming in but you're not sure if this is a real business yet. Forming a legal entity feels like overkill.
At some point, that changes. Here's how to figure out when.
Selling as a sole proprietor
If you haven't set up any business entity, you're already operating as a sole proprietor by default. That's not inherently wrong — it's how most small resellers run things, and it works until it doesn't.
The core problem is personal liability. A buyer claims your vintage electronics started a fire. Someone sues over an item they say was counterfeit. You sell a kid's toy that gets recalled. Without an LLC, a successful claim doesn't stop at your business — it reaches your personal bank account, your car, whatever you own. An LLC puts a legal wall between your business and your personal life.
When the math starts to work
There's no official income threshold that triggers "now you need an LLC." But most tax professionals start suggesting it once reselling generates $5,000–$10,000 in annual profit. At that level, the cost of formation and annual maintenance starts to make sense.
A few situations that tend to accelerate the decision:
You want a proper business bank account. You can technically open one as a sole proprietor with a DBA (Doing Business As) filing, but presenting an LLC with an EIN is cleaner at most banks. It also makes your bookkeeping defensible — the IRS is more likely to accept business expenses as legitimate when they're running through a clearly separate account.
You're selling anything with physical risk. Electronics, children's items, tools, anything that plugs in or could theoretically injure someone. If a buyer makes a claim, you want it pointed at the LLC, not at you personally.
Reselling has become your primary income. At that point you're running a real business. Structure it like one.
Which state to form in
Delaware and Wyoming get recommended constantly because of their flexible LLC laws and low fees. That advice applies to tech startups seeking venture capital, not to someone selling sneakers on StockX.
If you live in Ohio and form in Delaware, you still have to register as a foreign LLC in Ohio — and pay Ohio's fees on top of Delaware's. Two annual reports, two sets of compliance requirements, no real benefit for a small operation.
Form in your home state unless you have a specific reason not to.
What you actually need
A registered agent. Required for every LLC — a person or company with a physical address in your state who can receive legal notices and official mail. You can serve as your own if you have a physical in-state address (a PO box doesn't qualify). Many resellers use a service specifically to keep their home address off public records, which are searchable online in most states.
Articles of organization. The document you file with your state to create the LLC. Most states have online portals now. For a single-member LLC with a straightforward structure, this takes under an hour.
An EIN. Your Employer Identification Number — basically a Social Security Number for your business. Free from the IRS website, takes about 10 minutes to get online. You'll need it to open a business bank account and for tax purposes.
An operating agreement. Not legally required in every state, but worth having regardless. It documents who owns the business, how decisions get made, what happens if you bring in a partner, and what happens if you wind it down. Without one, your state's default LLC rules fill the gap — which may not match what you'd actually want.
What it costs
State filing fees vary more than most people expect. Kentucky charges $40. Massachusetts charges $500. Most states land somewhere between $75 and $150. On top of the one-time filing fee, most states also charge an annual report fee to keep the LLC active — usually $25–$100/year.
A registered agent service runs $50–$300 a year depending on the provider. If you use a formation service to handle the paperwork for you (rather than filing directly with the state), budget an additional $0–$200 above state fees.
Realistic first-year cost for most resellers: $150–$600.
After you're set up
Get your EIN if you haven't already. Open a business bank account and run all reselling income and expenses through it. Don't pay personal expenses from the business account.
That last point isn't just good practice — it's legally important. A court can decide your LLC protection is void if you've been blending personal and business finances, a concept called "piercing the corporate veil." The protection holds as long as you treat the LLC as a genuinely separate entity. Blur that line consistently and the protection can disappear.
Protect your brand name
Once you've formed the LLC and picked your business name, consider whether it's worth trademarking it. An LLC protects your personal assets from business liability — a trademark protects the name itself. Without one, another seller can start using your brand name and there's not much you can do about it legally.
Trademarking your reselling brand? Markavo handles the trademark filing process for you — they file with the USPTO, monitor for conflicting applications, and follow up if issues come up. Worth looking at if you're serious about protecting your brand name long term.
Before you settle on a business name
If you're planning to operate under a brand name rather than your own name, check that the username is actually available on the platforms where you sell before it becomes your legal business name. There's nothing worse than filing LLC paperwork for "VintageVaultCo" only to find that username is already taken on Poshmark and Etsy.
Username Inspector checks availability across eBay, Poshmark, Depop, Etsy, Grailed, Vinted, Mercari, Whatnot, Bonanza, Ruby Lane, and Chairish at the same time — takes about ten seconds.
Frequently asked questions
Do I need an LLC to sell on eBay?
No. eBay doesn't require any particular business structure — you can sell as an individual. But once reselling generates real income, an LLC protects your personal assets from buyer disputes and liability claims, and makes business banking easier.
How much does it cost to form an LLC?
State filing fees run from about $50 to $500 depending on where you live, with most states between $75 and $150. Add $50–$300 per year for a registered agent service if you use one. Total first-year cost for most resellers: $150–$600.
Should I form my LLC in Delaware?
Probably not. Delaware's advantages are designed for companies raising outside investment. If you live elsewhere and form in Delaware, you'll still need to register as a foreign LLC in your home state, paying fees in both places. For most resellers, forming at home is cheaper and simpler.
What is a registered agent?
A registered agent receives official legal notices on behalf of your LLC — things like lawsuits, tax notices, and state correspondence. Every LLC needs one. You can be your own if you have a physical in-state address, but many resellers pay a service ($50–$300/year) to keep their home address out of public records.
Can I open a business bank account without an LLC?
Yes, some banks offer sole proprietor accounts with a DBA filing. But an LLC with an EIN is more straightforward — fewer questions at the bank, cleaner tax records, and a clearer separation between business and personal finances.
