What Is an LLC?
A Limited Liability Company (LLC) is a business structure authorized by state law that combines the liability protection of a corporation with the tax simplicity of a sole proprietorship or partnership. The “limited liability” part means that your personal assets — your home, car, savings — are generally protected if your business is sued or owes debts.
Without an LLC (or other formal structure), operating as a sole proprietor means your personal and business assets are the same in the eyes of the law. A single lawsuit or unpaid debt could put your personal finances at risk. An LLC creates a legal barrier between you and the business.
LLCs are governed at the state level, which is why the process, costs, and requirements vary depending on where you form your LLC. Every state allows LLCs, but the rules differ.
Note: This guide covers the general process that applies in most states. Always verify specific requirements with your state’s Secretary of State office before filing. Requirements can change, and some industries have additional licensing requirements beyond basic LLC formation.
Benefits of an LLC
Personal Liability Protection
This is the primary reason most small business owners form an LLC. If your business is sued and a judgment is entered against it, the claimant can generally only go after business assets, not your personal savings, home, or car. This protection is not absolute — courts can “pierce the corporate veil” if you commingle personal and business funds or use the LLC fraudulently — but for most scenarios, it provides meaningful protection.
Pass-Through Taxation
By default, an LLC is taxed as a pass-through entity. This means the business itself does not pay federal income tax. Instead, profits and losses “pass through” to the owners, who report them on their personal tax returns. This avoids the double taxation that C-Corps face (where the corporation pays tax on profits, and shareholders pay tax again on dividends).
Tax Flexibility
An LLC can elect to be taxed as a sole proprietorship (default for single-member), partnership (default for multi-member), S-Corp, or C-Corp. This flexibility lets you optimize your tax treatment as your business grows without changing your legal structure.
Credibility and Professionalism
“John Smith LLC” or “Acme Consulting LLC” signals to clients, vendors, and banks that you are a legitimate business operation. Many enterprise clients and government contracts require vendors to be formally organized as an LLC or corporation.
Easier Business Banking and Credit
Banks and credit card companies prefer to work with formal business entities. An LLC with an EIN can open a business checking account, apply for business credit cards, and establish business credit — all of which are difficult or impossible as a sole proprietor.
Step-by-Step Registration Guide
Step 1: Choose Your State
Form your LLC in the state where you primarily do business. You might have heard that Delaware, Wyoming, or Nevada are “better” for LLCs. That advice is mostly relevant for larger corporations or companies with outside investors. If you are a small business owner operating in Texas, form in Texas. Forming in another state means paying that state’s fees plus registering as a foreign LLC in your home state anyway — double the cost and compliance.
Step 2: Choose and Check Your Business Name
Your LLC name must be unique in your state, must include “LLC,” “Limited Liability Company,” or an abbreviation thereof, and cannot include words that imply it is a government agency (like “FBI” or “Treasury”).
Search your state’s Secretary of State business name database (free, usually at sos.[state].gov) to confirm availability. Also check the USPTO trademark database and verify the domain name is available for your future website. Need a name? PrestoKit’s Business Name Generator can help you brainstorm and check availability.
Step 3: Appoint a Registered Agent
A registered agent is a person or company designated to receive official legal and tax correspondence on behalf of your LLC. Every state requires one. The agent must have a physical address in the state (not a P.O. box) and be available during business hours. You can be your own registered agent (if you have a physical address in the state), or use a registered agent service for $50-150/year.
Step 4: File Articles of Organization
Articles of Organization (called Certificate of Formation or Certificate of Organization in some states) is the official document that creates your LLC. You file it with your state’s Secretary of State. Most states offer online filing.
The form typically asks for: LLC name, registered agent name and address, principal business address, names of LLC members/managers, and purpose of the business (usually “any lawful business” is acceptable). Filing fees range from $50 to $500 depending on the state.
Step 5: Create an Operating Agreement
An operating agreement is an internal document that describes how your LLC will be managed. It is required by law in some states and strongly recommended in all others. Even for a single-member LLC, having one reinforces the legal separation between you and your business.
Key provisions include: ownership percentages, how profits and losses are distributed, how decisions are made, what happens if a member wants to leave, and what happens if the LLC dissolves. Use PrestoKit’s Contract Generator as a starting point for your business agreements.
Step 6: Get Your EIN
An Employer Identification Number (EIN) is your business’s federal tax ID. Apply free at irs.gov — the online application takes five minutes and your EIN is issued immediately. You need an EIN to open a business bank account, hire employees, and file business taxes. Even single-member LLCs with no employees should get one to keep your Social Security number off business documents.
Step 7: Open a Business Bank Account
Open a dedicated business checking account immediately after formation. This is non-negotiable. Commingling personal and business funds is the primary reason courts pierce the corporate veil and strip LLC liability protection. Bring your LLC formation documents, EIN, and a personal ID. Popular options include Mercury (online, no fees) and traditional banks like Chase or Bank of America.
Step 8: Obtain Necessary Licenses and Permits
Forming an LLC is separate from getting business licenses. Depending on your industry and location, you may need a general business license from your city or county, professional licenses (for regulated fields like law, medicine, real estate), sales tax permit if selling taxable goods, and zoning or home occupation permits if working from home. Check with your city and county business offices.

Filing Costs by State
The initial filing fee is just one cost. Many states also require annual or biennial reports with additional fees. Here are filing fees for major states:
Fees change periodically. Always verify current fees on your state’s official Secretary of State website before filing. New York’s publication requirement (requiring new LLCs to publish a notice in local newspapers for six weeks) is the most expensive quirk in the country — factor this in if forming in New York.
Single-Member vs. Multi-Member LLC
Single-Member LLC
A single-member LLC has one owner. For tax purposes, the IRS treats it as a “disregarded entity,” meaning the LLC’s income and expenses are reported directly on the owner’s personal tax return (Schedule C), just like a sole proprietorship. Despite this tax simplicity, the LLC still provides the legal liability protection. This is the most common structure for freelancers, consultants, and solo entrepreneurs.
Multi-Member LLC
A multi-member LLC has two or more owners (members). By default, it is taxed as a partnership — the LLC files a Form 1065 information return, and each member receives a Schedule K-1 showing their share of income, deductions, and credits, which they report on their personal returns. Multi-member LLCs require a robust operating agreement that clearly addresses how profits are split, how decisions are made, and what happens when a member wants to exit.
Key Differences
LLC vs. S-Corp: Which Is Right for You?
The S-Corp vs. LLC question is actually a tax question, not a legal structure question. You can have an LLC that is taxed as an S-Corp. The question is whether the S-Corp tax election makes financial sense for your situation.
How S-Corp Taxation Works
With a standard LLC (sole proprietor or partnership taxation), all net business income is subject to self-employment tax (15.3%). With S-Corp election, you split your income into two categories: a “reasonable salary” (subject to payroll/FICA taxes) and “distributions” (not subject to self-employment tax). This can significantly reduce your tax burden at higher income levels.
Example: $120,000 Net Business Income
S-Corp Added Costs
S-Corp election adds complexity and cost: you must run payroll (cost: $50-150/month), file a separate business tax return (Form 1120-S, cost: $1,000-3,000+ per year from an accountant), and maintain more rigorous bookkeeping. The break-even point is generally around $80,000-100,000 in net profit per year. Below that, the added costs likely exceed the tax savings.
Our recommendation: Start with a standard LLC. Once your net profit consistently exceeds $80,000/year, consult a CPA about whether S-Corp election makes sense for your specific situation. Do not let the S-Corp conversation distract you from the more important work of building your business.
After You Register: Staying Compliant
Forming your LLC is the beginning, not the end of your compliance obligations. Most states require ongoing filings to keep your LLC in good standing.
- Annual or biennial reports. Most states require LLCs to file a periodic report (and pay a fee) to confirm the business is still active and update contact information. Missing this filing can result in your LLC being dissolved by the state.
- Separate finances. Always keep business and personal money separate. Never pay personal expenses from the business account. This is the single most important ongoing practice for maintaining liability protection.
- Update your registered agent if needed. If your registered agent changes, file the update with your state promptly. Missed legal notices can result in default judgments.
- Privacy policy for websites. If your LLC operates a website, most states require a privacy policy. PrestoKit’s free Privacy Policy Generator can help you create one.
- Business insurance. Liability protection from an LLC is important, but it is not a substitute for business insurance. General liability insurance ($500-2,000/year) covers claims that arise from your business operations.
Frequently Asked Questions
How long does it take to form an LLC?
Online filing is processed in 1-3 business days in most states. Some states like Delaware and Wyoming offer same-day processing. Others, like New York, can take 2-4 weeks. If you are in a hurry, most states offer expedited processing for an additional fee ($25-100).
Can I form an LLC in a different state than where I live?
Yes, but if you are doing business in your home state, you will also need to register as a foreign LLC in that state, paying additional fees and maintaining a registered agent there. For most small businesses, the simplest and cheapest approach is to form in the state where you primarily operate.
Do I need a lawyer to form an LLC?
No. The filing process is straightforward enough to do yourself in most states. Where a lawyer adds value: if you have multiple members and need a complex operating agreement, if you are in a highly regulated industry, or if you have specific asset protection concerns. For simple single-member LLCs, DIY filing plus a template operating agreement is sufficient.
What is the difference between an LLC and a corporation?
Both provide liability protection. A corporation (C-Corp) is a more formal structure with shareholders, a board of directors, required annual meetings, and double taxation (unless it elects S-Corp status). LLCs are more flexible, less formal, and typically better suited for small businesses. Corporations are generally preferred when planning to raise venture capital, issue stock to many investors, or eventually go public.
Can an LLC have employees?
Yes. An LLC can hire employees just like any other business entity. You will need an EIN, register with your state for employer taxes, and set up payroll. The LLC members themselves are not typically treated as employees for tax purposes (they receive distributions, not W-2 wages) unless the LLC has elected S-Corp tax status.
What happens if I do not maintain my LLC properly?
Failing to file annual reports can result in your LLC being dissolved by the state (administratively dissolved). More seriously, commingling funds or failing to maintain the LLC as a separate legal entity can allow courts to “pierce the corporate veil,” exposing your personal assets to business liabilities — defeating the entire purpose of forming an LLC.
Can I convert my sole proprietorship to an LLC?
Yes. Most states allow you to convert an existing sole proprietorship to an LLC by filing Articles of Organization. You will then transfer business assets to the LLC, open a new business bank account under the LLC, update vendor and client agreements to reflect the new entity, and get a new EIN. It is not automatic — you need to actively move business activity into the new LLC.
Is an LLC right for a side hustle?
It depends on your risk exposure. If your side hustle involves any client work, physical products, events, or activities where someone could get hurt or sue you, an LLC is worth the $100-500 filing fee. If you are just selling items on eBay or doing occasional odd jobs, the compliance overhead may not be worth it at low income levels. As your side hustle grows and involves more client contracts, an LLC becomes increasingly worthwhile.
