No, you do not need an LLC to legally sell online. You can sell as a sole proprietor from day one. An LLC is optional protection, not a permission slip. What it buys is a legal separation between your business debts and your personal assets, for a one-time state filing fee of $35 to $500 depending on the state (2026 state fee schedules; average US filing fee $132, LLC University, 2026). Here is when that is worth paying for and when it is not.
Current as of July 28, 2026. Data changes; this page is reviewed quarterly.
What you actually need to sell online
A sole proprietorship exists the moment you start selling. There is nothing to file to create one. What you may need, regardless of structure:
A sales tax permit in states where you have nexus and sell taxable goods. A local business license, which many cities require of sole proprietors too. An EIN, free from the IRS, required if you have employees and useful for opening a business bank account. A DBA if you trade under a name that is not your own, typically $10 to $100. None of these require an LLC.
What an LLC actually does, and does not do
Does: separates business liability from personal assets, so a business lawsuit or debt generally cannot reach your home or personal savings, provided you keep finances genuinely separate. Adds credibility with suppliers and some platforms. Offers tax election flexibility as you grow.
Does not: reduce your taxes by default, a single-member LLC is taxed exactly like a sole proprietorship unless you elect otherwise. Protect you from your own negligence or personal guarantees. Substitute for insurance. And it does not protect you at all if you run business money through a personal account, the behavior that collapses the separation courts look for.

Filing handled for you, registered agent available, and the state fee passed through at cost. Useful when you want the paperwork right the first time instead of learning your state's portal.
See MyCorp Filing Options →2026 filing costs, by state
State filing fees range from $35 in Montana to $500 in Massachusetts, per 2026 state schedules. Kentucky is $40, Arkansas $45, and a cluster of states including Arizona, Colorado, Hawaii, Iowa, Michigan, Minnesota, Mississippi, Missouri, and New Mexico charge $50. On the high end: Nevada $425, Tennessee $300, Texas $300. The US average is $132.
Ongoing costs matter more than the filing fee. The average LLC annual fee is $91 (LLC University, 2026), but the spread is enormous: Arizona, Missouri, New Mexico, and Ohio require no annual report at all, while California charges an $800 minimum franchise tax every year regardless of revenue. Registered agent service, if you use one, adds roughly $100 to $300 a year.
File in the state where you actually operate. Forming in a "cheap" state you do not live in usually means registering as a foreign LLC at home too, and paying both.
The honest decision rule
Skip the LLC for now if you are testing an idea, selling digital products or services with low liability, and earning under a few thousand dollars. The filing fee is better spent on inventory or ads until the business proves itself.
Form the LLC when any of these are true: you have real revenue, you carry inventory or physical risk, clients ask for it, you are signing leases or contracts, you have a partner, or you simply have personal assets you would hate to expose. Most sellers reach that line faster than they expect.

Open a business bank account immediately and route everything through it, this is what actually preserves the liability protection you just paid for. Get an EIN from the IRS, which is free and takes minutes. Calendar your state's annual report deadline, since most states dissolve non-compliant LLCs.

What people ask me
Do I need an LLC to sell online?
No. You can legally sell online as a sole proprietor with no filing at all. An LLC is optional liability protection, not a requirement to start selling.
How much does an LLC cost in 2026?
State filing fees range from $35 in Montana to $500 in Massachusetts, with a US average of $132. Annual fees average $91 but range from $0 in states like Arizona and New Mexico to $800 in California.
What do I actually need to sell online legally?
Possibly a sales tax permit where you have nexus, a local business license, an EIN if you have employees, and a DBA if you use a trade name. None of these require an LLC.
Does an LLC lower my taxes?
Not by default. A single-member LLC is taxed identically to a sole proprietorship unless you make a different tax election as the business grows.
When should I actually form an LLC?
When you have real revenue, carry inventory or physical risk, sign contracts or leases, take on a partner, or have personal assets you would not want exposed to a business claim.
Should I form my LLC in a cheaper state?
Usually no. File where you actually operate. Forming elsewhere typically requires registering as a foreign LLC in your home state as well, so you pay twice.
