If you are making money online — freelancing, selling digital products, running a SaaS, dropshipping, affiliate marketing, or building tools — and you do not have an LLC, you are leaving yourself exposed. One lawsuit, one unhappy customer, one contract dispute, and your personal assets (bank account, car, home) are on the table.
Forming an LLC takes less than 30 minutes and costs as little as $35 depending on your state. This guide walks you through every step, compares formation services, and covers tax strategies that can save you thousands per year.
A sole proprietorship is the default when you start making money. There is no separation between you and the business. If someone sues the business, they sue you. Your personal bank accounts, your car, your savings — all exposed.
An LLC (Limited Liability Company) creates a legal wall between your personal assets and your business liabilities. Here is what you get:
If a customer sues your online business, they can only go after business assets — not your personal savings, home, or car. This is the single biggest reason to form an LLC. One lawsuit can wipe out everything you own as a sole proprietor.
An LLC can be taxed as a sole proprietorship (pass-through), an S-Corp, or a C-Corp. This flexibility lets you choose the structure that minimizes your tax burden as your income grows. The S-Corp election alone can save $5,000-15,000+ per year in self-employment taxes once you earn over $50,000.
Having "LLC" after your business name signals legitimacy to clients, partners, and banks. You can open a business bank account, accept business credit cards, and build business credit — all separate from your personal finances.
| Feature | Sole Prop | Single-Member LLC | LLC (S-Corp Election) |
|---|---|---|---|
| Liability Protection | None | Full | Full |
| Formation Cost | $0 | $35-500 | $35-500 + $0 IRS filing |
| Self-Employment Tax | 15.3% on all profit | 15.3% on all profit | 15.3% on salary only |
| Tax Filing | Schedule C | Schedule C | Form 1120-S + W-2 |
| Separate Bank Account | Optional | Required | Required |
| Best For | Hobby income | Under $50K profit | Over $50K profit |
LLC formation costs vary dramatically by state. Here are the 10 cheapest states to form an LLC in 2026:
| State | Filing Fee | Annual Report | State Tax | Total Year 1 |
|---|---|---|---|---|
| Kentucky | $40 | $15 | None | $40 |
| Arkansas | $45 | $150 | None | $45 |
| Mississippi | $50 | $0 | None | $50 |
| New Mexico | $50 | $0 | None | $50 |
| Wyoming | $100 | $60 | None | $100 |
| Montana | $70 | $20 | None | $70 |
| Colorado | $50 | $10 | None | $50 |
| Iowa | $50 | $60 (biennial) | None | $50 |
| Michigan | $50 | $25 | None | $50 |
| Delaware | $90 | $300 | None | $90 |
Most expensive states: California ($70 filing + $800 annual franchise tax), Massachusetts ($500 filing), Illinois ($150 filing + $75 annual report), New York ($200 filing + $9 publication requirement that costs $500-1,500 in NYC).
Popular advice says "form in Wyoming or Delaware." But if you live and operate in another state, you will need to register as a foreign LLC in your home state too — paying both states' fees. For most solo founders, forming in your home state is simpler and cheaper unless you have a specific legal reason (holding company, privacy, etc.).
Your LLC name must be unique in your state and include "LLC" or "Limited Liability Company." Search your state's business name database to check availability. Most states have a free online search tool on the Secretary of State website.
Brainstorm unique business names instantly. Check domain availability and get branding ideas.
Try It Free →Every LLC needs a registered agent — a person or service that receives legal documents on behalf of your business. You can be your own registered agent (free) or hire a service ($50-300/year). If you value privacy or work from home, a registered agent service keeps your home address off public records.
This is the actual LLC formation document. File it with your state's Secretary of State office. Most states offer online filing. You will need:
Even for a single-member LLC, an operating agreement is critical. It establishes that you treat the LLC as a separate entity (which protects your liability shield). It outlines ownership, profit distribution, management structure, and dissolution procedures.
Free from the IRS at irs.gov. Takes 5 minutes online. You need this for a business bank account, tax filings, and hiring contractors.
Never mix personal and business finances. This is the number one way people accidentally "pierce the corporate veil" and lose their liability protection. Open a separate business checking account using your EIN.
Track every business expense from day one. Use free tools or Wave (free accounting software). Keep receipts for everything.
Create a professional business plan for your LLC in minutes. Includes financial projections and market analysis.
Build Your Plan →You can form an LLC yourself for just the state filing fee, or use a formation service. Here is how the top services compare:
| Service | Base Price | Registered Agent | EIN Filing | Operating Agreement | Total Year 1 |
|---|---|---|---|---|---|
| DIY | $0 | $0 (self) | $0 (IRS) | Free template | State fee only |
| Northwest | $39 | $125/yr (free Y1) | Included | Included | $39 + state fee |
| ZenBusiness | $0 | $199/yr (free Y1) | $70 | Included | $0 + state fee |
| LegalZoom | $0 | $299/yr | $70 | $99 | $299 + state fee |
| Incfile | $0 | $119/yr (free Y1) | $70 | Included | $0 + state fee |
If you are comfortable with forms: DIY. It takes 30 minutes and saves you $100-300. If you want someone to handle it: Northwest Registered Agent. Best customer service, transparent pricing, no upselling. Avoid: LegalZoom's renewal pricing — that $299/year registered agent fee adds up fast.
The IRS provides EINs for free. Any website charging you $50-150 for an EIN is just filing the free IRS form on your behalf. Go directly to irs.gov.
Open a dedicated business checking account. You will need your EIN, Articles of Organization, and operating agreement. Good free options:
Once your LLC profit exceeds roughly $50,000-60,000 per year, electing S-Corp taxation can save you $5,000-15,000+ per year in self-employment taxes. Here is how:
As a default LLC, you pay 15.3% self-employment tax on all profit. With S-Corp election, you pay yourself a "reasonable salary" and only pay the 15.3% on that salary. The remaining profit passes through as distributions — exempt from self-employment tax.
| Annual Profit | SE Tax (Default LLC) | SE Tax (S-Corp, $50K Salary) | Annual Savings |
|---|---|---|---|
| $60,000 | $8,478 | $7,065 | $1,413 |
| $80,000 | $11,304 | $7,065 | $4,239 |
| $100,000 | $14,130 | $7,065 | $7,065 |
| $150,000 | $20,389 | $7,065 | $13,324 |
| $200,000 | $24,887 | $7,065 | $17,822 |
How to elect S-Corp: File IRS Form 2553 by March 15 of the tax year you want it to take effect (or within 75 days of forming your LLC). It is free to file. You will need to run payroll for yourself, which costs $0-40/month with services like Gusto or Wave Payroll.
