How to Start an LLC: A Step-by-Step Guide

What an LLC Is — and Why Founders Choose One

A limited liability company (LLC) is a business structure created under state law. It gives owners — called members — the personal asset protection of a corporation while keeping the tax simplicity and flexibility of a sole proprietorship or partnership.

The main reasons founders choose an LLC:

• Limited liability — your personal assets (home, savings, car) are generally shielded from business debts and lawsuits.

• Pass-through taxation — by default the LLC pays no federal income tax itself; profits flow to the members' personal returns.

• Credibility and flexibility — an LLC signals legitimacy to clients and banks, and it can elect different tax treatment as it grows.

How to Start an LLC, Step by Step

Formation happens at the state level, so exact forms, fees, and timelines vary from state to state. Most states, however, follow the same core sequence:

1. Choose a name. It must be distinguishable from other businesses registered in your state and usually must include an LLC designator (such as "LLC" or "Limited Liability Company"). Check availability on your state's Secretary of State website.

2. Appoint a registered agent. Every LLC needs one — more on that below.

3. Decide how it will be managed — member-managed (the owners run it) or manager-managed (appointed managers run it).

4. File the Articles of Organization (in some states called a Certificate of Formation or Organization) and pay the filing fee. This is the step that legally creates your LLC. Online filings are often approved within a few business days.

5. Create an operating agreement. Most states don't require it, but it's strongly recommended — it sets out ownership, profit sharing, and decision-making, and banks frequently ask for it. Even single-member LLCs should have one.

6. Get an EIN from the IRS. An Employer Identification Number is a free federal tax ID. Applying online usually returns it immediately, and you'll use it to open a bank account, hire employees, and file taxes.

7. Handle the rest — open a dedicated business bank account, obtain any required licenses or permits, and register for state taxes where applicable.

What Is a Single-Member LLC?

A single-member LLC (SMLLC) is simply an LLC with one owner. For federal income tax, the IRS treats it as a disregarded entity by default — meaning the IRS doesn't see it as separate from you. You report business income and expenses on your personal return (Schedule C), much like a sole proprietor.

A few distinctions matter:

• "Disregarded" is a tax label, not a legal one. Your LLC is still a separate legal entity, so the liability protection remains fully in place.

• Employment and excise taxes are treated differently. If your SMLLC has employees or owes certain excise taxes, it is treated as a separate entity and must use its own name and EIN.

• You can change the tax treatment. An SMLLC can elect to be taxed as a corporation or an S corporation by filing the appropriate IRS form — often to reduce self-employment tax once profits become substantial.

Does an SMLLC need an EIN? Strictly speaking, a disregarded SMLLC with no employees and no excise-tax liability can use the owner's Social Security number. In practice, most new owners get an EIN anyway — banks usually require one, and it keeps your SSN off business paperwork.

The Registered Agent: Your LLC's Official Point of Contact

Every LLC must name a registered agent in each state where it is formed or registered. The agent's job is to receive official mail on the LLC's behalf — legal documents (such as service of process in a lawsuit) and state notices.

The requirements are consistent across states:

• A physical street address in the state of formation (no P.O. boxes).

• Availability during normal business hours to accept documents in person.

Your options:

• Be your own agent — free, but your name and address become part of the public record, and you must be reliably available.

• Use a trusted individual — a friend, family member, or your attorney who meets the requirements.

• Hire a registered agent service — a modest annual fee that keeps your address private and forwards documents to you.

Costs and Staying Compliant

Ongoing obligations vary by state, but commonly include:

• The initial filing fee for the Articles of Organization.

• An annual (or biennial) report — sometimes called a statement of information — often with a small fee.

• In some states, a franchise tax or annual LLC tax.

• Your registered agent's fee, if you use a service.

Keep accurate records, file on time, and keep business and personal finances strictly separate — that separation is what preserves your liability protection.
