Best LLC for eBay sellers: reselling, nexus and 1099-K
eBay's tax problem is not the sales tax — eBay handles that. It is that the form eBay sends the IRS reports everything that passed through your account, and proving what it cost you is entirely your job.
The short answer
A sole proprietorship is adequate for casual reselling. Form a single-member LLC once you are sourcing deliberately, holding real inventory value, or selling anything with a safety profile.
Published
Reselling is the purest version of a business that starts by accident. Nobody incorporates before clearing out a garage. The structure question arrives later, usually in the same month as a tax form that reports a much larger number than the seller thinks they earned.
The short answer
Sole proprietor while it is occasional. A single-member LLC once you are buying to sell, holding stock worth protecting, and generating profit you would miss. The LLC does not change the tax; it separates the business from your personal assets and makes the books defensible.
The 1099-K is gross, and your tax is not
eBay reports payments processed through your account on a Form 1099-K. That figure is gross receipts — before eBay's fees, before shipping, and crucially before what the item cost you. Your taxable profit can be a small fraction of it, or negative.
| Line | Example |
|---|---|
| Reported on the 1099-K | $48,000 |
| Cost of goods sold | $27,000 |
| Marketplace and payment fees | $6,500 |
| Shipping and packaging you paid | $4,200 |
| Actual taxable profit | $10,300 |
There is a separate rule worth knowing for personal items: selling something you owned for less than you paid produces no deductible loss, but it is also not income. Mixing personal clear-outs with sourced inventory in one account is what makes that distinction hard to prove later.
Sales tax is handled, mostly
eBay collects and remits US sales tax on your marketplace sales as a facilitator. Nothing to register, nothing to file. The exceptions are the same as on any marketplace: sales you make anywhere else are yours, and inventory stored in a state can still raise a registration question independently of who collects.
Where reselling has its own risks
- Authenticity claims. Selling counterfeits, even unknowingly, is an account-ending problem and a legal one. Sourcing at volume from unverified channels is how it happens.
- Condition disputes. eBay's buyer protection resolves most disputes toward the buyer. Detailed photographs and honest condition grading are the only real defence.
- Recalled and prohibited items. Children's products, certain electronics and anything under recall carry liability that resale does not remove.
- Item specifics for regulated goods. Some categories require compliance information you must actually have.
If you are not a US person
- No S-corp election — Section 1361 bars non-resident alien shareholders.
- Form 5472 with a pro-forma Form 1120 annually for a foreign-owned US single-member LLC, $25,000 penalty for failure to file.
- Holding inventory in the US is a meaningful connection. Selling your own country's stock to US buyers from abroad is a different position from operating a US-based warehouse.
When to revisit
| Trigger | What to reconsider |
|---|---|
| Buying deliberately to resell | Form the entity and start tracking cost of goods properly. |
| Net profit durably above ~$80,000 | Model the S-corp election. |
| Adding your own storefront | Sales tax becomes yours on those sales. |
| Moving into new or private-label goods | Product liability and importer obligations arrive. |
| Renting storage or a unit | Inventory in a state you may not have considered. |
