Updated August 7, 2026. Quick answer: for a lot of small side businesses, a sole proprietorship is fine and an LLC is an expense with a story attached. The honest test is not “does an LLC protect me” — it does, within limits — but “what is the specific thing I am protecting, and is insurance the better answer to it?”
What the shield actually does
An LLC separates business liabilities from personal assets. That is real, and it matters when the business can generate a claim larger than the business itself — customers on your premises, work that can damage property, employees, products people consume or rely on, or a lease or loan in the business’s name.
What it does not do is protect you from your own acts. If you personally do the negligent thing, you are personally liable whatever the entity is. It also does not survive a personal guarantee, which is what a landlord or lender will ask for from a new LLC with no history — and it does not protect you if the separation is not real in practice.
The question the affiliate sites do not ask
For most one-person service businesses, liability insurance is the more direct answer — it pays the claim, where an LLC only limits who the claim reaches. An LLC with no insurance still loses the business’s assets and your time. Insurance without an LLC still pays.
The strongest position is usually both, and the honest ordering is insurance first. That is the opposite of the ordering you will meet on sites paid per formation.
When the answer is genuinely yes
- You have a partner. Two people in business without an entity is a general partnership by default, with joint liability for each other’s acts. This is the strongest case on the list.
- You hold property or equipment in the business — particularly rental property: the mortgage question there is specific and important.
- A client or platform requires it to contract with you. Common, and a perfectly good reason.
- You are building something to sell or bring investors into.
- Your trade carries real physical risk to people or property.
And the cost is not the filing fee
The number to compare against is not the state’s formation fee. It is the five-year cost of ownership, which ranges from $135 to $4,130 across the exact-verified states — the full table, with the annual costs most fee lists omit. In a state at the top of that range, an LLC for a small side income can cost more than the income.
If the business is a side income rather than a livelihood, start with what the tax treatment actually is: the 1099-K reporting threshold, and remember that a single-member LLC changes almost nothing about how you are taxed by default — the IRS disregards it, and the income lands on your personal return exactly as it did before.

If the business starts after 60 it meets three systems a younger business does not — the earnings test, benefit taxation, and a Medicare premium set two years later.
Whichever way that comes out, one setup step is free and is worth doing either way: an EIN comes directly from the IRS at no charge, and a sole proprietor can get one without forming anything. The IRS’s own page says plainly that you never have to pay a fee for one.
And whichever way you go, the money question afterwards has a counter-intuitive answer: a single-member LLC owner takes draws rather than a salary, and is taxed on the profit whether or not any of it is withdrawn.
