Do You Actually Need an LLC? A Plain-English Guide for Solo Founders

The LLC is the most over-sold product in the solopreneur economy. It's also, at the right moment, genuinely worth having. The trick is knowing which side of that line you're on.

What an LLC actually does

A Limited Liability Company does one headline thing: it separates your business's debts and legal problems from your personal assets. If the business gets sued or can't pay its bills, your house and savings are (with important exceptions) not on the table. By default it changes almost nothing about your taxes — a single-member LLC is taxed exactly like a sole proprietorship unless you elect otherwise.

What it doesn't do: magically reduce your taxes, make you look bigger than you are, or protect you from your own professional mistakes in many cases. Anyone selling it as a tax hack is selling.

When you genuinely want one

• Real liability exposure — clients can claim damages, you handle their data or money, you sell physical products, people set foot on your premises.
• Meaningful revenue — once the business clears hobby scale, the ~£/$100–500 all-in cost is cheap insurance.
• Contracts and clients that require it — many B2B clients simply won't onboard a sole proprietor.
• A co-founder — shared ownership without an entity and an operating agreement is a friendship time-bomb.

When it can wait

If you're pre-revenue, testing an idea, selling a low-risk digital product at small scale — a sole proprietorship plus a separate bank account is a perfectly respectable starting point (here's exactly what you can and can't do without an LLC). Forming an entity you don't need yet mostly buys you annual report fees and paperwork. Start simple; upgrade when one of the triggers above appears.

The honest cost breakdown

• State filing fee: roughly $50–500 depending on state (this is the only mandatory cost).
• Registered agent: $0 if you're your own, ~$100–150/year for a service (worth it if you value privacy or move around).
• Formation service: $0–300 on top, depending on tier.
• Ongoing: annual report fees and, in some states (looking at you, California's $800 franchise tax), real money every year.

DIY vs formation services

Filing yourself on your state's website is genuinely doable in an hour — the form is simpler than most people expect. A formation service (Northwest, ZenBusiness, and the rest of the crowd) earns its fee when you want a registered agent bundled in, hand-holding on the follow-up steps (EIN, operating agreement, compliance calendar), or you're a non-US founder navigating it remotely. Our full comparison of the major formation services covers who each one suits and where the "free" offers make their money, and Northwest vs ZenBusiness is the direct comparison.

One myth worth killing: the Delaware/Wyoming thing

For a solo founder, forming in a "famous" state you don't live in usually means paying two states instead of one — you'll still have to register where you actually operate. Delaware is for venture-backed startups. Form where you live; move later if the situation genuinely changes.

What is the owner of an LLC called?

Legally, a member. A solo owner is the sole member of a single-member LLC. Several owners each hold a membership interest, not shares. "Shareholder" and "partner" belong to other structures.

Most small LLCs are member-managed: the owners run the company. A member who does that is a managing member, which is the title banks and state forms usually expect. Manager-managed LLCs, where members appoint someone else to run the company, show up in family and property deals and rarely in a company of one.

CEO, founder, president, principal and owner are business titles an LLC can adopt. They are fine on an email signature. On a contract, sign as "Jane Smith, Member" or "Managing Member" of the LLC, on behalf of the company. That signature is part of keeping the liability separation intact. The operating agreement is where the members and their percentages are recorded. The person who filed the paperwork, the organizer, is not automatically an owner. A formation service often fills that role. A registered agent is not an owner at all.

Can you start a business without an LLC?

Yes. The moment you sell something with the intent to make a profit, you are a sole proprietor. No filing and no permission. You can invoice, take card payments, get an EIN, open a business bank account, file a DBA if you want a trade name, deduct expenses, hire and sign contracts. A single-member LLC is taxed like a sole proprietorship by default, so the entity is not a tax discount.

What you give up is liability separation: business debts and lawsuits are personal. Some business clients will not contract with a sole proprietor, and "LLC" on a proposal is a mild credibility signal. That is the list. You can also form an LLC before you have customers, to reserve a name or to hold a property. The state does not check that you are trading, but it keeps charging: annual reports, a registered agent, and in some states a flat tax whether you earned anything. California's franchise tax, about $800 a year, is the one people get surprised by.

An ignored LLC does not quietly disappear. Missed reports bring late fees, then loss of good standing, then administrative dissolution, which removes the liability protection, sometimes without the owner noticing. Some state taxes keep accruing until you formally dissolve. If you are finished with a dormant LLC, file the dissolution. If you are not ready to maintain an entity, staying a sole proprietor is the sensible sequence, not a delay.

Do you need an LLC for a blog, podcast or side hustle?

Form one when the project can hurt someone financially, or when it earns enough that its problems could hurt you. Until then the filing is mostly annual fees.

Side-hustle income is taxable from the first dollar either way. A separate bank account and a record of income come before the filing fee.

How do you get an EIN?

An EIN is the business's nine-digit federal tax ID. Banks ask for one to open a business account, and it keeps your Social Security number off the W-9s you give clients. You do not need employees to get one, and the IRS issues it for free.

• US founders. Use the IRS EIN Assistant (search "apply for an EIN" on irs.gov) on a weekday during the hours it posts. Have the legal name exactly as filed, the formation state, and the responsible party's name and SSN or ITIN. A single-member LLC takes about 15 minutes and the number is issued at the end. Save the CP 575 confirmation letter straight away. The bank will ask for it, and it is shown once. Apply after the state approves the LLC so the names match. One EIN per responsible party per day.
• Sole proprietors. Not required if you have no employees. Worth having so your SSN stays off client paperwork.
• Founders without a US Social Security number. The online assistant is closed to you. Form SS-4 by phone to the IRS international line, or by fax, is still free. A paid service in that case is buying help with the phone queue, not the right to a number.

Decline the $50 to $300 "EIN filing" add-on in a formation checkout if you have a US tax ID. It submits the same free form, often more slowly. The week the number arrives, open the business bank account and store the confirmation letter with the formation papers.

Form an LLC when the business is real enough to protect — not to make it feel real.

Frequently asked questions

Is it worth it to start an LLC?

It's worth it when the business has something to protect: real liability exposure, meaningful revenue, clients whose contracts require an entity, or a co-founder. Before any of those, the ~$100–500 cost plus annual fees mostly buys paperwork — a sole proprietorship with a separate bank account is a respectable start, and upgrading later takes about an hour.

How much does it cost to form an LLC?

The mandatory cost is your state's filing fee, roughly $50–500 depending on the state. Optional extras: a registered agent service (~$100–150/year) and a formation service ($0–300). Budget also for ongoing annual report fees — and note outliers like California's $800 annual franchise tax.

Do I need an LLC to start freelancing or selling online?

No. You can operate legally as a sole proprietor from day one in the US — income is reported on your personal return. An LLC becomes worth it when there's real liability exposure, meaningful revenue, a co-founder, or clients whose contracts require an entity.

Does an LLC save you money on taxes?

By default, no — a single-member LLC is taxed identically to a sole proprietorship. Tax advantages only appear later, at higher profits, via elections like S-corp status, which bring their own payroll and admin costs. Forming an LLC purely as a "tax hack" is a myth sold by people with formation packages to sell.

Should I form my LLC in Delaware or Wyoming?

Almost certainly not, as a solo founder. You'll still have to register (and pay) in the state where you actually live and operate, so the famous-state route usually means double fees for no benefit. Delaware's advantages are built for venture-backed corporations, not one-person businesses.
