Key Takeaways

- Exact steps, fees, and taxes vary by state — this is general information, not legal advice.
- An LLC is just the legal wrapper — you still need something to sell; making and selling your own products is one of the best ways to make it profitable.
- Many people form an LLC once their business is earning, to add legal protection and credibility.
If you're turning a side hustle or idea into a real business, you've probably heard you should “form an LLC.” A limited liability company is one of the most popular structures for small businesses because it's relatively simple to set up and it separates your personal finances from your business. This guide explains what an LLC is, how to start one step by step, and what to do once it's formed — including how to actually make it profitable.
Please note
This article is general educational information, not legal, tax, or financial advice. LLC requirements, fees, and tax treatment vary by state and change over time — always check your state's official filing office and consider consulting a qualified attorney or accountant for your specific situation.
What is an LLC?
An LLC (limited liability company) is a legal business structure that sits between a sole proprietorship and a corporation. Its defining feature is limited liability: the business is treated as separate from you personally, so if it owes money or is sued, your personal assets — home, car, savings — are generally protected. It's the most popular structure for small U.S. businesses because it's simple to run yet offers real protection.
Why do you need an LLC?
You don't always need one on day one — many people start as a sole proprietor and form an LLC once they're earning or taking on real risk. Here's what an LLC gives you:
- Personal-asset protection. Business debts and lawsuits generally can't reach your personal property.
- Credibility. An “LLC” after your name reassures customers, suppliers, and banks that you're a real business.
- Tax flexibility. Profits “pass through” to your personal return by default, but you can elect other treatments as you grow.
- Simplicity. Far less paperwork and fewer formalities than a corporation — ideal for solo founders and small teams.
- Easier banking & funding. A registered entity makes it simpler to open business accounts and access credit.
How do you start an LLC?
To start an LLC, choose a compliant business name, appoint a registered agent to receive legal documents, file your articles of organization with your state (and pay the filing fee), create an operating agreement that sets how the LLC is run, and obtain an EIN from the IRS so you can open a business bank account. Requirements and costs vary by state.
What do you need to start an LLC?
Forming an LLC is mostly paperwork. Before you file, line up these essentials:
- A compliant business name that's available in your state.
- A registered agent with a physical address in the state.
- Your articles of organization (the formation document) plus the state filing fee.
- An operating agreement setting out ownership and how the LLC is run.
- An EIN from the IRS and a dedicated business bank account.
Have these ready and the actual filing often takes under an hour.
How to start an LLC
With the essentials ready, here's the step-by-step. Rules, fees, and timelines vary by state — we've added a few California and New York examples to show how much they can differ.
Step 1: Choose a name
Pick a business name that's available and compliant with your state's rules. Most states require it to be unique among registered businesses and to include an indicator like “LLC” or “L.L.C.” Search your state's business registry to confirm availability, and check that a matching domain and social handles are free. Many states let you reserve a name while you prepare — California, for example, holds a name for 60 days for about $10.
Step 2: Name a registered agent
A registered agent (California calls it the “agent for service of process”) is the person or company designated to receive legal and official mail for your LLC, and must have a physical address in the state. You can act as your own agent, appoint someone you trust, or hire a registered-agent service — the last option adds privacy and makes sure documents are handled even when you're away.
Step 3: File your articles of organization
This step officially creates your LLC: you file the articles of organization (sometimes a certificate of formation) with your state's filing office and pay a fee. Fees and extras vary widely — and this is where LA and NYC diverge sharply. In California, filing is about $70, but every LLC then owes an $800 minimum annual franchise tax. In New York, filing is about $200, plus a publication requirement: you must publish formation notices in two newspapers for six weeks in your county — in Manhattan (New York County) that alone can run $1,000–$2,000+. Always check your own state's current fees before filing.
Step 4: Create an operating agreement
An operating agreement is an internal document setting out ownership percentages, how profits are split, voting rights, and what happens if a member leaves. Not every state requires one — but New York actually mandates it by law, and it's strongly recommended everywhere, even for a single-member LLC, because it reinforces the separation between you and the business.
Step 5: Get an EIN and open a bank account
Apply for an EIN (Employer Identification Number) from the IRS — it's free and acts as your business's tax ID, needed to hire, open accounts, and file taxes. Then open a dedicated business bank account. Keeping business and personal money separate is essential: it protects your limited-liability status and makes bookkeeping and taxes far easier.
After you form your LLC: licenses, taxes, and staying compliant
Once your LLC exists, a few ongoing basics keep it in good standing:
- Licenses and permits — depending on your industry and location, you may need local business licenses or permits.
- Taxes — LLCs are flexible: by default profits “pass through” to your personal return, but you can elect other treatments; an accountant can advise what fits.
- Annual requirements — many states require an annual or biennial report and fee to keep the LLC active.
- Clean records — keep business finances separate and organized to preserve liability protection.
Again, specifics vary by state and situation — treat this as a starting checklist, not legal advice.
Bonus: decide what your LLC sells
An LLC is just the legal wrapper — the real question is what it sells. Here are the main categories, roughly from easiest to start to highest-margin.
Online services
Freelancing, consulting, design, marketing, or coding — sell your skills with almost no startup cost. An LLC adds the credibility that wins bigger clients and contracts.
Local & labor services
Cleaning, landscaping, repairs, trades, tutoring, or event help — hands-on work billed by the job or hour, usually the fastest route to first revenue.
Physical goods (resale)
Buy and resell, dropship, or stock inventory to sell online or locally. Simple to understand, though margins are typically slim and competition is high.
Digital products & designs
Templates, SVGs, presets, printables, and courses — create them once and sell forever, at margins approaching 100%.
DIY, custom & print-on-demand products
For many small LLCs this is the highest-margin route: make custom, personalized products people want — engraved gifts, signs, jewelry, decor, and apparel — and sell them on Etsy, your own store, or at local markets. A desktop craft machine turns your LLC into a genuine product business.
Make products with an affordable craft machine
A desktop laser cutter and engraver is the maker's most versatile tool — it cuts and engraves wood, acrylic, leather, and slate for personalized products. For apparel, an in-house DTF or DTG printer makes custom shirts. A compact all-in-one like the xTool O1 Omni covers several product types from one machine:
xTool O1 Omni
Most versatile starter
With UV, DTG, and DTF in one compact machine, the O1 Omni lets you offer a whole catalog — custom shirts, printed mugs and phone cases, engraved-look signs, and more — without buying separate equipment.
That flexibility makes it a smart first machine: you can test which products actually sell before you specialize, then reinvest profits into scaling the winners.

How much does it cost to start an LLC?
The main cost is your state's filing fee, which varies widely by state, plus optional costs like a registered-agent service or name reservation. Many states also charge a recurring annual report fee. Getting an EIN is free. You can file an LLC yourself directly with your state to keep costs down, or use a formation service for convenience — either way, check your state's current fees before you start.
Frequently asked questions
Do I need an LLC to start a business?
No — you can operate as a sole proprietor without forming anything, and many people start that way. An LLC becomes worthwhile when you want to protect your personal assets from business liabilities, add credibility, or formalize ownership. It's a common step as a business grows, but it isn't required to begin.
How much does it cost to form an LLC?
The primary cost is your state's filing fee, which varies significantly from state to state, plus any optional services like a registered agent. Many states also charge an annual or biennial fee to keep the LLC active. Getting an EIN from the IRS is free. Check your state's official site for current amounts.
Can I form an LLC myself?
Yes. You can file the articles of organization directly with your state's business office, usually online, and apply for a free EIN yourself. Formation services and attorneys can handle it for a fee if you prefer convenience or have a more complex situation, but a straightforward single-member LLC is often filed without help.
How are LLCs taxed?
By default, an LLC is a “pass-through” entity, meaning profits and losses flow to the owners' personal tax returns rather than being taxed at the business level. LLCs can also elect to be taxed differently in some cases. Tax rules are complex and vary, so consult a qualified accountant about the best treatment for you.
What's the difference between an LLC and a sole proprietorship?
A sole proprietorship is the default when you do business as an individual — simple, but with no separation between you and the business, so your personal assets are exposed. An LLC is a separate legal entity that provides limited-liability protection and more flexibility, in exchange for filing paperwork and paying state fees.
In short: forming an LLC is mostly a series of manageable paperwork steps — name, agent, articles, operating agreement, EIN, and bank account — with details that vary by state. But the LLC is just the container. What fills it with income is a product or service people want, and making and selling your own products is one of the most durable ways to get there.
