How to Register a Business in 2026: LLC, Sole Proprietor, or Corporation?

Between sole proprietorships, LLCs, S-Corps, and C-Corps, choosing a business structure can feel overwhelming. For most small business owners in 2026, the decision comes down to two options — here's how to choose and register the right way.

One of the first decisions every new entrepreneur faces is also one of the most confusing: how do I legally set up my business? Between sole proprietorships, LLCs, S-Corps, and C-Corps, the options can feel overwhelming — especially when the internet gives conflicting advice about which structure is "best."

The good news: for the vast majority of small business owners in 2026, the decision comes down to two options. This guide explains each structure in plain English, walks you through the registration process step by step, and helps you choose the right structure for your situation.

What Are the Main Types of Business Structures?

The four main types of business structures in the United States are sole proprietorship, limited liability company (LLC), S-corporation, and C-corporation. Each differs in how the business is taxed, how much personal liability protection it offers, and how complex it is to set up and maintain.

Here's a quick comparison:

Structure	Liability Protection	Tax Treatment	Setup Complexity	Best For
Sole Proprietorship	None	Pass-through	Minimal	Testing ideas, freelancers
LLC	Yes	Pass-through (flexible)	Low	Most small businesses
S-Corp	Yes	Pass-through	Moderate	Profitable businesses with owner salary
C-Corp	Yes	Double taxation	High	Venture-backed startups

For most people reading this guide, the decision is: sole proprietorship or LLC. Let's dig into both.

What Is a Sole Proprietorship and Is It Right for Me?

A sole proprietorship is the default business structure for anyone who starts working for themselves without formally registering a business entity. It's the simplest structure — you can start one today, with zero paperwork and zero cost.

Advantages:

No registration required (you're automatically a sole proprietor when you start earning)
Simplest taxes: business income and expenses go on Schedule C of your personal tax return
Minimal administrative overhead

Disadvantages:

No personal liability protection. If your business is sued or can't pay its debts, your personal assets (savings, car, home) can be targeted.
Can be harder to open a business bank account or get business credit without a registered entity
May appear less professional to larger clients

When a sole proprietorship makes sense:

You're testing a business idea before committing fully
You're freelancing or consulting with minimal legal risk
Your work doesn't involve significant liability exposure (no physical locations, no employees, no high-stakes advice)

If you're a web developer freelancing for small businesses, a sole proprietorship might be fine to start. If you're running a cleaning business in someone's home, you want the liability protection of an LLC.

What Is an LLC and Why Do Most Small Businesses Choose It?

An LLC (Limited Liability Company) is a business structure that provides personal liability protection while maintaining pass-through taxation — meaning business profits flow directly to your personal tax return without being taxed at the business level first.

It's the most popular business structure for small businesses for good reason: it combines meaningful legal protection with relatively simple administration.

Key advantages of an LLC:

Personal liability protection. The LLC is a separate legal entity from you. If the business is sued or owes a debt, your personal assets are generally protected — the creditor can only go after business assets. This protection isn't absolute (courts can "pierce the corporate veil" if you comingle personal and business funds or commit fraud), but it's a significant shield for most situations.

Flexible taxation. By default, a single-member LLC is taxed like a sole proprietorship (Schedule C). A multi-member LLC is taxed like a partnership. You can also elect to be taxed as an S-Corp for potential self-employment tax savings once your business is profitable enough to justify it.

Credibility. "ABC Services LLC" signals to clients that you're a real, established business. This matters for landing larger clients and corporate contracts.

Operating flexibility. LLCs have minimal ongoing compliance requirements compared to corporations — no board meetings, no mandatory stock issuance, no complex governance documents required.

LLC disadvantages:

Setup cost ($50–$500 depending on state, plus annual fees)
Annual report or franchise tax requirements vary by state
Self-employment taxes still apply to LLC income (you pay both employer and employee portions of Social Security and Medicare taxes)

For most small business owners — consultants, service providers, e-commerce sellers, local businesses — an LLC is the right starting point.

What Is a Corporation (C-Corp vs S-Corp) and When Should I Use One?

A corporation is a more formal business entity that offers the strongest liability protection but comes with significantly more administrative complexity and cost. There are two main types relevant to small businesses: C-Corps and S-Corps.

C-Corporation:

The default corporate structure
Profits are taxed at the corporate level, then again when distributed to shareholders as dividends ("double taxation")
Required structure for venture capital funding
Best for startups planning to raise investment, go public, or grant stock options broadly
Most small businesses should not start as a C-Corp

S-Corporation:

A special tax election available to qualifying corporations or LLCs
Pass-through taxation like an LLC, but with a key difference: owner must pay themselves a "reasonable salary" (subject to payroll taxes), with remaining profits distributed as dividends (not subject to self-employment tax)
Can generate meaningful tax savings once your business earns $60,000+ in profit annually
Requires more administrative overhead (payroll, separate corporate formalities)
Cannot have more than 100 shareholders or foreign shareholders

When to consider an S-Corp election: If your LLC is consistently profitable and you're paying high self-employment taxes, converting to S-Corp taxation can save $5,000–$15,000 per year. Consult a CPA when your net profit consistently exceeds $50,000–$60,000 annually.

How Do I Choose Between an LLC and Sole Proprietorship?

Choose an LLC over a sole proprietorship if any of the following apply: your business could expose you to legal liability, you plan to hire employees, you want to open a business bank account easily, or you're working with corporate clients who prefer doing business with a registered entity.

A simple decision framework:

Choose a sole proprietorship if:

You're just starting and want to test the market before investing in setup costs
Your work is purely digital with minimal liability exposure
You're in a state with high LLC fees (California charges $800/year minimum franchise tax)

Choose an LLC if:

You'll be entering people's homes, handling others' property, or providing advice they'll act on
You have personal assets worth protecting (home equity, savings, investment accounts)
You want to build a business you might eventually sell
Your clients are businesses that require a W-9 or vendor registration

For most people, the $100–$300 LLC setup cost is a worthwhile insurance premium. You only need one liability incident to make it worth it.

How Do I Register an LLC Step by Step?

Registering an LLC involves five core steps: choosing a name, appointing a registered agent, filing Articles of Organization, creating an Operating Agreement, and getting your EIN. The entire process typically takes 1–5 business days and can be completed entirely online.

Step 1: Choose a business name

Your name must be unique in your state. Search your state's business registry (usually at the Secretary of State website) to confirm availability. The name must include "LLC," "Limited Liability Company," or an abbreviation.

Tips: choose something memorable, easy to spell, and available as a .com domain. Check trademark availability at the USPTO.

Step 2: Appoint a registered agent

A registered agent is a person or company authorized to receive legal documents on behalf of your LLC. The agent must have a physical address in the state of formation (not a P.O. Box).

You can be your own registered agent if you have a physical address in the state. Third-party registered agent services cost $50–$300/year and are worth it if you work from home (your home address becomes a public record otherwise) or if you may not always be available during business hours.

Step 3: File Articles of Organization

This is the official document that creates your LLC. Filed with your state's Secretary of State office (or equivalent). Most states allow online filing.

Required information typically includes:

LLC name and principal address
Registered agent name and address
Name(s) of the organizer(s)
Purpose of the business (can usually be "any lawful business purpose")
Management structure (member-managed or manager-managed)

Filing fees range from $50 (Kentucky) to $500 (Massachusetts). Processing time is usually 1–5 business days for online filings; expedited same-day processing is often available for an additional fee.

Step 4: Create an Operating Agreement

An Operating Agreement is an internal document that outlines how the LLC will be governed — how decisions are made, how profits are distributed, what happens if a member leaves, and how disputes are resolved.

Only a handful of states legally require Operating Agreements, but every LLC should have one regardless. Without one, you default to state LLC statutes, which may not match your intentions. For single-member LLCs, it also strengthens the case that your LLC is genuinely separate from you personally (relevant if liability ever comes into question).

Free templates are available from your state's SBA office or legal sites. Hire a business attorney for multi-member LLCs where ownership stakes and voting rights could become contentious.

Step 5: Get an EIN

An Employer Identification Number (EIN) is a federal tax ID for your business — think of it as a Social Security number for your LLC. You need it to:

Open a business bank account
Hire employees
File business taxes
Apply for business credit

Apply at IRS.gov/ein — it's free, takes about 10 minutes, and you receive your EIN immediately.

How Much Does It Cost to Register a Business?

The cost to register a business varies by state and structure. For an LLC, expect to spend $50–$500 on the initial filing fee, plus $0–$300 annually for renewal and registered agent fees.

Cost Item	Typical Range
LLC filing fee	$50–$500 (one-time)
Annual report / franchise tax	$0–$800/year (varies widely by state)
Registered agent service	$0–$300/year
Operating Agreement (attorney)	$0–$1,000
EIN	Free
Business bank account	$0–$25/month
Business license (if required)	$20–$200

Lowest-cost states for LLCs: Kentucky ($40), Colorado ($50), Montana ($35) Highest-cost states: California ($70 filing + $800 minimum franchise tax/year), Massachusetts ($500), Tennessee ($300)

If you're in a high-fee state and your business is entirely online, some entrepreneurs form their LLC in Wyoming (low fees, strong privacy laws) and register as a "foreign LLC" in their home state when required. Consult a CPA or attorney before this approach.

Do I Need a Business License in Addition to Registering?

Yes, in most cases — a business license is separate from business registration. Registration creates your legal entity; a business license permits you to operate in a specific location or industry.

Types of licenses and permits:

General business license: Many cities and counties require any business operating locally to obtain a general business license ($20–$200/year). Check with your city clerk or county website.

Professional licenses: Certain occupations require state-issued licenses regardless of business structure: contractors, real estate agents, accountants, attorneys, healthcare providers, cosmetologists, and many others. Check your state's licensing board requirements.

Industry-specific permits: Food businesses need health department permits. Businesses that sell physical goods may need a sales tax permit. Firearms dealers, liquor stores, and transportation companies have federal requirements.

Home occupation permit: If you're running a business from home, your city may require a home occupation permit ($20–$100/year).

Use the SBA's Business License & Permits tool to find requirements specific to your business type and location.

What Is an EIN and Do I Need One?

An EIN (Employer Identification Number) is a unique nine-digit federal tax identification number assigned to your business by the IRS. It functions like a Social Security number for your business.

You need an EIN if you:

Have employees (required)
Operate as a corporation or partnership (required)
Are an LLC that elected corporate taxation (required)
Want to open a business bank account (almost all banks require it)
File certain excise taxes

Sole proprietors without employees can technically use their Social Security number instead of an EIN, but an EIN is still recommended to protect your SSN from unnecessary exposure.

Getting an EIN is free and instant through the IRS website. You can also apply by fax or mail, but online is the fastest option.

Should I Register My Business in My Home State or in Delaware/Wyoming?

Register your business in your home state unless you have a specific reason not to. The advantage of Delaware and Wyoming for small businesses is often overstated.

The Delaware myth: Delaware has a well-developed body of corporate law and is the preferred state for venture-backed C-corporations. For LLCs, most small businesses see minimal benefit from Delaware formation — and still need to register as a foreign entity in their home state if they operate there, paying fees in both states.

Wyoming's genuine advantages: Wyoming LLCs offer strong privacy (no public disclosure of member names), no state income tax, and low fees. This can be advantageous for online businesses operated by entrepreneurs who value privacy and mobility.

The practical answer: Unless you're raising VC funding (use Delaware C-Corp), running an entirely online business with privacy concerns (consider Wyoming), or have been specifically advised by a business attorney, form your LLC in your home state and avoid the complexity of multi-state registration.

Start Your Business the Right Way

Registering your business properly is a one-time investment that protects everything you build afterward. Once you're set up, focus on what actually grows a business: finding customers and delivering value.
